CROSS REFERENCES TO OTHER APPLICATIONS 
     This application claims the benefit of U.S. provisional application No. 61/067,646, filed on Mar. 1, 2008, which is incorporated herein by reference. 
    
    
     BACKGROUND 
     The present invention generally relates to a device that may be used to connect to a duct (such as a length of pipe or tubing or a container spout), and in some embodiments, to an object (such as a pipe fitting, a piece of equipment, a tank or other container, or another duct), as well as kits and methods of use related to the device. More specifically, the device may be used to connect to ducts having different sizes and characteristics. In a preferred embodiment, the device acts as a coupling device to connect containers together where the containers&#39; spouts have a range of different sizes and shapes. Thus, the coupling device may be used to transfer the contents of one container to another container without spillage. 
     There are coupling systems known in the relevant art that are comprised of variable connecting means designed for use with different sizes and shapes of ducts (such as pipes and tubing). In these systems, a single connector may be used to connect to ducts having a variety of different sizes and shapes within a predetermined range. For example, a single connector having variable connecting means may be used to connect to a standard garden hose, a ¾″ nominal diameter steel pipe having NPT threads, or a 1″ Type L copper pipe. Examples of these types of connectors and systems are disclosed in U.S. Nonprovisional patent application Ser. No. 11/522,607 filed on Sep. 18, 2006, Ser. No. 11/879,346 filed on Jul. 17, 2007, Ser. No. 12/012,954 filed on Feb. 6, 2008, and U.S. Provisional Patent Application No. 61/062,428 filed on Jan. 25, 2008, and Ser. No. 61/066,258, entitled MODULAR COUPLING SYSTEM filed on Feb. 19, 2008, all of which also name as inventor the inventor of the present invention. The entire disclosure of each of these patent applications is incorporated herein by this reference. 
     There are instances, however, where it may be desirable to connect a coupling device to a duct (such as a length of pipe or tubing or a container spout) having multiple sizes, thread types, or compositions (such as steel, plastic or copper) in circumstances where thrust loads tending to blow the duct out from the coupling device are relatively small. In these circumstances, it may also be desirable to have a coupling device that is relatively simpler to operate and cheaper to manufacture. In addition, it may be desirable to have a coupling device that is designed more specifically for only temporary connection to ducts and objects. In such cases, it may also be desirable for the coupling device to be reusable, so that it can be used multiple times for connecting to ducts and objects having a variety of sizes and shapes. For example, the user of the coupling device may desire to fill a container with water from a garden hose. After the few seconds or minutes it takes to fill the container, both the container and the hose may be disconnected from the coupling device. It is desirable in this case that the coupling device be capable of being quickly and easily connected to and removed from the garden hose and the container. The user of the coupling device may then desire to use it to transfer the contents of one container to another container. In these cases, the containers may have different spout sizes and shapes, so that they cannot be directly connected together. For example, the user may desire to transfer milk from a milk bottle to a canteen, where the spout on the milk bottle is larger than the spout on the canteen. Again, because the connection is to be of short duration, it is desirable that the connection to and disconnection from the coupling device be quick and easy. 
     Further, because the reusable nature of the desired coupling device permits it to be used with ducts carrying different types of fluids, it may also be desirable that the coupling device be easily disassembled and reassembled for purposes of cleaning the coupling device. Alternatively, or in addition, the coupling device may have features that assist it in not being easily contaminated by such fluids. Further still, it may be desirable to have a coupling device that regulates the flow between the duct and the object. For example, it may be desirable to have a way to regulate the flow between the milk bottle and the canteen and to stop the flow of milk once the canteen is filled to the desired level. A coupling device having these features would be advantageous over other devices and methods that are not as flexible with respect to the variety of ducts and objects that may be connected. It would also be more advantageous over other methods and devices (such as use of a funnel) that are more difficult to use and more prone to spillage of the transferred fluid. 
     SUMMARY 
     The present invention is directed to a device and system, as well as related kits and methods of using the device and system, which meet the needs discussed above in the Background section. As described in greater detail below, the present invention, when used for its intended purposes, has many advantages over other devices known in the art, as well as novel features that result in a new device, kits and methods of using the device that are not anticipated, rendered obvious, suggested, or even implied by any prior art devices or methods, either alone or in any combination thereof. 
     In a preferred embodiment of the present invention, a device is disclosed that is adapted for connecting to a duct comprising a duct open end and a duct exterior surface adjacent to the duct open end having a size and shape adapted to be variable within a predetermined range. The device is comprised of a casing member and adjustable connecting means. The adjustable connecting means may be further comprised of one or more adjusting connector members. In some embodiments, different adjusting connector members may be adapted to be connected to different ranges of sizes and shapes of ducts. In these embodiments, the adjusting connector members may be part of a modularized system of adjusting connector members, all of which may be used interchangeably in their operation with the casing member. In this preferred embodiment, the adjusting connector member is further comprised of duct sealing means, a bracing member, thread engaging means, and adjusting member internal connecting means, all of which are described in more detail below. The duct sealing means may be comprised of a hollow duct seal member, which is adapted to be positioned adjacent to a portion of the duct exterior surface while the duct is connected to the duct seal member. The duct seal member may also be comprised of an inlet seal flange portion, an outlet seal flange portion, and a seal sheath portion extending between them that is shaped approximately as an hourglass (a portion of which is also approximately shaped as a hyperboloid). The bracing member supports the duct sealing means (described in more detail below) in operation of the device. In this preferred embodiment, the bracing member is approximately tubular in shape and has an inlet open end and an outlet open end. The duct seal member is positioned within the bracing member with the inlet seal flange portion positioned approximately adjacent to the open end of the bracing member. The positioning is “approximate” because other members, such as a portion of the thread engaging means, may be positioned between them. The adjusting member internal connecting means (described in more detail below) are for operatively connecting (which includes both removably or permanently connecting) the duct seal member, the bracing member, and the thread engaging member together. In some embodiments, the adjusting member internal connecting means may be comprised of an adhesive, adhesive tape, glue or epoxy, so that the volume between the duct seal member and the bracing member is sealed from the outside environment. In some embodiments, a compressible insert (described in more detail below) may be positioned in this volume between the duct seal member and the bracing member. Also in this preferred embodiment, the adjusting connector member is further comprised of thread engaging means (described in more detail below), at least a portion of which are positioned between the duct and the duct seal member while the duct is connected to the device. The thread engaging means are adapted for engaging any threads on the duct, as described in more detail below. 
     In this embodiment, the casing member is further comprised of casing connecting means, which are described in more detail below, adapted for connecting the casing member to the adjusting connector member. The casing connecting means may also be adapted to be connected to at least one additional adjusting connector member, so that the adjusting connector member is interchangeable with the at least one additional adjusting connector member in its operation with the casing member. The casing member may also be comprised of object connecting means, which are adapted to connect the casing member to an object, as described in more detail below. In another embodiment, the casing member is comprised of a case body, a case cap, and case cap connecting means, which are described in more detail below. The case body has a casing interior space and at least one case body open end adjoining the casing interior space. The case cap has a connector opening, which is adapted to receive the duct when it is connected to the device. The case cap connecting means removably or permanently connect the case cap to the case body at the case body open end, as described in more detail below. In these embodiments, the adjusting connector member may be adapted to be positioned approximately within the case body opening while the case cap is connected to the case body. In some of these embodiments, the case cap connecting means are comprised of a threaded portion on the case body adjacent to the at least one case body open end and a threaded portion on an opening of the case cap, so that the case cap is adapted to be screwed down onto the case body. In other embodiments of the present invention, the casing member is further comprised of a case body conduit section, a case body connecting section, case body section connecting means for operatively connecting the at least one case body conduit section to the case body connecting section (which are described in more detail below), and casing connecting means for connecting the at least one case body conduit section to an adjustable connector member. The case body connecting means may also comprise flow regulating mechanisms in some embodiments. In these embodiments, the case body section connecting means are adapted to connect at least one additional case body connecting section to the at least one case body conduit section and at least one additional case body conduit section to the case body connecting section so that all of such sections and additional sections are interchangeable as part of a modularized system. Generally, a method of using the device comprises connecting the at least one adjusting connector member to the casing member using the casing connecting means. Another method comprises operatively inserting the duct into the device. The present invention also includes a kit comprising the casing member and the at least one adjusting connector member, as well as a kit comprising the at least one adjusting connector member and the at least one additional adjusting connector member. 
     Thus, if the user of the system desires to connect two containers having different spout sizes together so that fluid may be transferred from one container to another, the user may unscrew the case cap from one end of the case body, place an adjusting connector member adapted to receive the size of one container spout in the case body open end, and then screw the case cap down onto the open end until the adjusting connector member is sealed between them. The user may then unscrew the case cap from the other end of the casing member, place another modular adjusting connector member adapted to receive the size of the other spout in the open end, and then screw the cap down onto the end until the adjusting connector member is sealed between them. The user may then connect each of the spouts to the device in the manner described in more detail below. Once the user has finished using the device, the spouts may be removed. The adjusting connector member and the casing member may then each be disassembled for cleaning and then reassembled for another use of the device. It is to be noted that this summary does not describe other embodiments of the present invention, which are described in more detail below. 
     In another embodiment of the present invention, the device may comprise a duct seal member, at least a portion of which is adapted to be positioned adjacent to a portion of the duct exterior surface, and thread engaging means adapted for drawing the duct down into the duct seal member by engaging any threads on the duct exterior surface, as described in more detail below. At least a portion of the thread engaging means may be positioned between the duct and the duct seal member while the duct is operatively connected to the device. In yet another embodiment, the device may comprise an adjusting connector member and casing connecting means for operatively connecting the adjusting connector member to a casing member, as described in more detail below. In this embodiment, the adjusting connector member is further comprised of a duct seal member, a bracing member, and adjusting member internal connecting means for operatively connecting the duct seal member to the bracing member, as described in more detail below. The duct seal member may be further comprised of an inlet seal flange portion and a seal sheath portion, which extends from the inlet seal flange portion and is shaped approximately as an hourglass. The devices of these two embodiments may also further comprise the casing member. In still another embodiment, the device comprises a casing member, a plurality of duct support members, adjustable connecting means, and casing connecting means, all of which are described in more detail below. The casing member may have a casing interior space and comprise at least one open end in fluid communication with the casing interior space. In this embodiment, the plurality of duct support members extend away from the casing member and are adapted for holding the duct in place relative to the casing member. The adjustable connecting means are adapted for connecting to a duct, and the casing connecting means are for connecting the adjustable connecting means to the casing member at the at least one open end, all as described in more detail below. In all of such embodiments, the duct may typically comprise a duct open end and a duct exterior surface adjacent to the duct open end, wherein the duct exterior surface has a size and shape adapted to be variable within a predetermined range, so that the adjustable connecting or adjusting connector member are adapted to be operatively connected to ducts within the predetermined range. 
     Therefore, the coupling system and device of the present invention meet the requirements described above in the Background section. The coupling device has a simple, easy to use and reuse design that allows its connection to ducts having multiple sizes, thread types, or compositions (such as steel, plastic or copper) in circumstances where thrust loads tending to blow the duct out from the coupling device are relatively small. In addition, the coupling device is designed more specifically for only temporary connection to ducts. Ducts may be quickly and easily connected to and then removed from the coupling device. The device may also be simpler to manufacture than other variable connecting means. The coupling device may also be easily disassembled and reassembled for purposes of cleaning the coupling device. In some embodiments, the coupling device may have features that assist it in not being easily contaminated by fluids transferred through the device, such as by sealing the volume between the duct seal member and the bracing member. Further still, the coupling device may regulate the flow between the duct and the object. The coupling system should also reduce spills of fluid because of the seal adapted to be formed between the duct and the device. The coupling device therefore possesses features that make it advantageous over other devices and methods that are not as flexible with respect to the variety of ducts and objects that may be connected. 
     There has thus been outlined, rather broadly, the more primary features of an embodiment of the present invention. There are additional features that are also included in the various embodiments of the invention that are described hereinafter and that form the subject matter of the claims appended hereto. In this respect, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the following drawings. This invention may be embodied in the form illustrated in the accompanying drawings, but the drawings are illustrative only and changes may be made in the specific construction illustrated and described within the scope of the appended claims. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of the description and should not be regarded as limiting.

     DETAILED DESCRIPTION 
     Reference will now be made in detail to the preferred aspects, versions and embodiments of the present invention, examples of which are illustrated in the accompanying drawings. While the invention will be described in conjunction with the preferred aspects, versions and embodiments, it is to be noted that the aspects, versions and embodiments are not intended to limit the invention to those aspects, versions and embodiments. On the contrary, the invention is intended to cover alternatives, modifications, portions and equivalents, which may be included within the spirit and scope of the invention as defined by the appended claims. 
     One embodiment of the present invention  15  is illustrated in  FIG. 1 , which presents a partially exploded perspective view of the device  15 . In this illustrated embodiment of the present invention, the device  15  is comprised of a casing member  20  and adjustable connecting means (described in more detail below) that are adapted for connecting the device  15  to at least one duct (pipe  70  in the case of adjusting connector member  30 , but not illustrated for adjusting connector member  40 ). In various embodiments, the adjustable connecting means may be comprised of at least one adjusting connector member (adjusting connector member  30  in this embodiment). The casing member  20  is further comprised of casing connecting means, which are described in more detail below, adapted for connecting the casing member  20  to the at least one adjusting connector member (adjusting connector member  30 ). In the illustrated embodiment, the at least one adjusting connector member (adjusting connector member  30 ) is further comprised of casing connecting means for connecting the at least one adjusting connector member (adjusting connector member  30 ) to the casing member  20 . The casing member  20  is also adapted to be connected to at least one additional adjusting connector member (adjusting connector member  40  in this embodiment) that comprises the same operative casing connecting means (described in more detail below) as that comprising the at least one adjusting connector member (adjusting connector member  30 ). Thus, the at least one adjusting connector member (adjusting connector member  30 ) is interchangeable with the at least one additional adjusting connector member (adjusting connector member  40 ) in its operation with the casing member  20  as part of a modularized system of interchangeable adjusting connector members (adjusting connector members  30 ,  40 ). Generally, the at least one adjusting connector member (adjusting connector member  30 ) is capable of connecting to ducts (pipe  70 ) that have a different range of sizes and shapes as the range of ducts that may be connected to the at least one additional adjusting connector member (adjusting connector member  40 ). As is also illustrated in  FIG. 11A  through  FIG. 11C , the at least one adjusting connector member (adjusting connector member  30 ) is further comprised of duct sealing means (duct seal member  31  in this embodiment), a bracing member  32 , thread engaging means (thread engaging member  33  in this embodiment), adjusting member internal connecting means for operatively connecting the duct seal member  31  to the bracing member  32  and the thread engaging member  33  (an adhesive, which is not illustrated, in this embodiment), and casing connecting means for connecting the at least one adjusting connector member (adjusting connector member  30 ) to the casing member  20 , all of which are described in more detail below. In operation of the device  15 , and referring again to  FIG. 1 , the duct (pipe  70 ) is inserted into the at least one adjusting connector member (adjusting connector member  30 ), so that a portion of the duct seal member  31  is positioned adjacent to the exterior surface of the duct (pipe  70 ) around its perimeter, preferably forming a fluid-tight seal between the duct (pipe  70 ) and the at least one adjusting connector member (adjusting connector member  30 ), all as described in more detail below. As is also described in more detail below, at least a portion of the thread engaging member  33  is positioned between the duct (pipe  70 ) and the duct seal member  31  while the duct (pipe  70 ) is connected to the device  15 . The thread engaging member  33  may generally serve to guide the duct (pipe  70 ) into the at least one adjusting connector member (adjusting connector member  30 ) when the duct (pipe  70 ) is inserted into the device  15 , or it may assist in holding the duct (pipe  70 ) in place relative to the device  15  while the duct (pipe  70 ) is connected to the device  15 , or both. The bracing member  32  generally serves to support the duct seal member  31 , as described in more detail below. It is to be noted that in various embodiments, the present invention may comprise any embodiment of the adjusting connector member  30 ,  40  or the casing member  20  individually, as well as in combinations. 
     Referring to the device  15  illustrated in  FIG.1  and the device  915  illustrated in  FIG. 19  as an example, the ducts (pipes  70 ,  870  and bottle spout  875   a ) that are connected to the device  15 ,  915  may have a tubular shape and may be comprised in whole or in part of conduit, tubing (including medical or food grade tubing), pipeline, duct, hose, channel, vent or other similar objects or combinations of such objects that may be currently known in the relevant art or that may be developed in the relevant art in the future. The ducts (pipes  70 ,  870  and bottle spout  875   a ) may also have other shapes in other embodiments. For example, the ducts (pipes  70 ,  870  and bottle spout  875   a ) may have a cross-section that is approximately elliptical, triangular, square, rectangular, pentagonal, hexagonal, another polygonal shape, or another shape or combination of such shapes. The ducts (pipes  70 ,  870  and bottle spout  875   a ) may also be comprised of any materials suitable for constructing conduit, tubing, pipeline, duct, hose, channel, vent, containers, or similar objects. Examples include metals (such as steel, steel alloys, aluminum, copper, brass, or other metals or metal alloys), polymers (such as polyvinyl chloride (PVC), polyethylene, acrylonitrile butadiene styrene (ABS), rubber, synthetic rubber (including NEOPRENE), silicon, and other polymers), wood, glass, fiberglass, carbon-based and other composites, or other materials or a combination of such materials. Further, the ducts (pipes  70 ,  870  and bottle spout  875   a ) may have a variety of different thread types on the end thereof. For example, the ducts (pipes  70 ,  870  and bottle spout  875   a ) may have American Standard Pipe Taper Threads (NPT), American Standard Straight Coupling Pipe Threads (NPSC), American Standard Taper Railing Pipe Threads (NPTR), American Standard Straight Mechanical Pipe Threads (NPSM), American Standard Straight Locknut Pipe Threads (NPSL), American Standard Pipe Taper Threads (Dryseal; NPTF), American Fuel Internal Straight Pipe Thread (NPSF), British Standard Pipe Threads (tapered—BSPT, and parallel—BSPP), or any other type of threads. Alternatively, the duct (pipes  70 ,  870  and bottle spout  875   a ) may have no threads or a different type of connector means (such as a VICTAULIC® groove) on the end thereof. It is also to be noted that the device  15 ,  915  of the present invention may be used for ducts (pipes  70 ,  870  and bottle spout  875   a ) transporting gases or liquids or both, so that references to a “fluid” herein are intended to refer to both gases and liquids, as they may be carried by the ducts (pipes  70 ,  870  and bottle spout  875   a ) in each case. In still other embodiments, the ducts (pipes  70 ,  870  and bottle spout  875   a ) may comprise fittings or other connecting devices. 
     In the embodiment of the present invention illustrated in  FIG. 1 , the device  15  is generally comprised of a casing member  20 , two adjusting connector members  30 ,  40 , and casing connecting means, all of which are described in more detail below. In the illustrated embodiment, the casing member  20  is further comprised of a case body  21 , a case cap  22 ,  23  positioned at each end of the case body  21 , and case cap connecting means, which are described in more detail below. Case cap  23  may have any of the characteristics, features, structure, functions and operation as case cap  22 , as described in more detail elsewhere herein. The case caps  22 ,  23  each have a connector opening  22   a ,  23   a , respectively, positioned therein. The case caps  22 ,  23  may be removably or permanently connected to the case body  21  by the case cap connecting means, which are described in more detail below. Although the casing member  20  is comprised of portions that are approximately tubular-shaped and conically-shaped in the illustrated embodiment, the casing member  20  may have other shapes in other embodiments of the device  15 , preferably so that the casing member  20  has an interior space  20   a  and a connector opening  22   a  (and other connector openings  23   a  in some embodiments) adjoining the interior space  20   a , wherein the connector openings  22   a ,  23   a  are of a size and shape adapted to cooperate with the adjusting connector members  30 ,  40  in operation of the device  15 , all as described in more detail below. As an example of an alternate shape, a portion of the exterior surface of the casing member  20  may be hexagonal in shape when viewed in cross-section from above an end of the casing member  20 . As other examples, the casing member  20  may also have approximately elliptical, triangular, square, rectangular, pentagonal, another polygonal shape, other shapes having arcuate or linear portions, or another shape or combination of such shapes, as long as the casing member  20  cooperates with the adjusting connector members  30 ,  40  in operation of the device  15 , all as described in more detail below. 
     Further, as illustrated in the device  15  of  FIG. 1 , the case body  21  may be comprised of two or more case body sections and case body section connecting means for removably or permanently connecting the case body sections together, which means are described in more detail below. For example, in the illustrated embodiment, the case body  21  is comprised of two case body conduit sections  21 ′,  21 ″ and a case body connecting section  21   i . The case body conduit section  21 ′ is comprised of an end component  21   a  and a case body channel component  21   b . The case body end component  21   a  is comprised of an open end  21   c  and threads  21   d  that are adjacent to the open end  2   c . Preferably, the case body end component  21   a  is comprised of a suitable rigid or semi-rigid material so that it is rigid enough to support the adjusting connector member  30  in operation of the device  15  while the adjusting connector member  30  is connected to the device  15 . For example, the case body end component  21   a  may be comprised of metal (such as steel, steel alloys, aluminum, copper, brass, or other metals or metal alloys), polymers (such as PVC, polyethylene, polypropylene, ABS, and other polymers), wood, fiberglass, carbon-based or other composites, or other materials or a combination of such materials. The case body channel component  21   b  is preferably comprised of a flexible or semi-flexible material, so that the case body channel component  21   b  may bend, but is rigid enough so that it doesn&#39;t collapse or become unduly constricted while being bent or in other operation of the device  15 . Examples include rubber, synthetic rubber (including NEOPRENE), elastomers or other elastic polymers (such as silicone), or combinations of such materials, along with a combination that may including cloth, fabric, metal mesh, or other flexible or semi-flexible materials. In other embodiments, the case body channel component  21   b  may be comprised of a rigid or semi-rigid material, such as that comprising the case body end component  21   a . Referring to the device  15  illustrated in  FIG. 1  as an example, in each case, the preferred material is dependent upon a number of different factors, such as the anticipated size, shape and type of the ducts (pipe  70 ), the type of connection to be made to the ducts (pipe  70 ), the size, shape, material composition and configuration of the adjusting connector members  30 ,  40 , the anticipated operating or installation temperatures of the device  15 , the type of fluid carried by the ducts (pipe  70 ), the desired wall thickness and weight of the case body  21 , the preferences of the user of the device  15 , and other factors. The case body conduit section  21 ′ may be fabricated using any suitable means. For example, a case body end component  21   a  constructed of PVC may be formed by injection molding and a case body end component  21   a  constructed of a metal alloy may be formed by metal injection molding. As another example, a case body channel component  21   b  constructed of rubber or silicone may be cast in a mold. The case body end component  21   a  and the case body channel component  21   b  may be connected together by any appropriate means, such as a threaded connection, clasps, clamps, clips, pins, hinges, adhesives, adhesive tapes, epoxies, welding, fusing, nails, screws, nuts, bolts, or other types of fasteners or connectors, either alone or in conjunction with one another in different combinations. Alternatively, the case body end component  21   a  and the case body channel component  21   b  may be fabricated together as a single piece. It is to be noted that the case body end component  21   a  and the case body channel component  21   b  may each have a different shape in other embodiments. For example, the case body end component  21   a  and the case body channel component  21   b  may each have different cross-sectional shapes or may be longer or shorter than as illustrated in  FIG. 1 . In the case of a device  15  designed for room temperature domestic use and capable of accommodating ducts (pipe  70 ) in the range of ¾″ to ½″ nominal diameter, the case body end component  21   a  is preferably constructed of PVC and has the illustrated shape with a major inside diameter of approximately 1½ inches reducing down to a minor inside diameter of approximately ½″. In such cases, the case body channel component  21   b  is preferably constructed of rubber, with a more rigid portion (such as harder rubber or PVC) adjacent to the case body connecting section  21   i , and has the illustrated shape with a uniform inside diameter of approximately ½″. The case body conduit section  21 ″ is comprised of an end component  21   e  and a case body channel component  21   f . The case body end component  21   e  is comprised of an open end  21   g  and threads  21   h  that are adjacent to the open end  21   g . Preferably, the case body end component  21   e  and the case body channel component  21   f  are comprised of the same type of materials as, and have features substantially the same as, the case body end component  21   a  and the case body channel component  21   b , respectively. 
     In the illustrated embodiment, the case body connecting section  21   i  is positioned between the two case body conduit sections  21 ′,  21 ″ and serves to connect the two case body conduit sections  21 ′,  21 ″ together in embodiments comprising such sections  21 ′,  21 ″. In various embodiments, the case body connecting section  21   i  may also perform other functions in operation of the device  15 . For example, as illustrated in  FIG. 1  and  FIG. 2 , the case body connecting section  21   i  is further comprised of a valve mechanism. The valve mechanism may be used to regulate the flow, or to completely stop the flow, of fluids through the device  15  when and as desired. This feature may greatly enhance operation of the device  15 , as described in more detail below and illustrated in connection with  FIG. 19 . In such cases, the case body connecting section  21   i  may comprise any type of valve or flow regulating mechanism currently known in the relevant art or that may be developed in the relevant art in the future. For example, the case body connecting section  21   i  may comprise a check-valve, gate valve, ball valve, pressure regulator, backflow prevention device, needle valve, or a combination of such devices. In other embodiments, as illustrated in  FIG. 3 , the case body connecting section  121   i  may be comprised of an orifice mechanism. This type of mechanism may slow the flow of fluid through the device  115 , but not in a manner that is typically adjustable by the user of the device  115 . In yet other embodiments, as illustrated in  FIG. 4 , the case body connecting section  221   i  may be comprised of a tubular section that merely acts to connect the two case body conduit sections  221 ′,  221 ″ together. In other embodiments, and referring to  FIG. 1  as an example, the case body connecting section  21   i  may take the form of almost any suitable type of fitting or connecting device. For example, the case body connecting section  21   i  may be in the form of a tee, a “Y” connector, or a 90 degree elbow. Case body connecting sections  21   i  shaped as an elbow may also have bends of 45 degrees, 22½ degrees, or another bend angle. Where the case body connecting section  21   i  is in the form of a tee or a “Y” connector, the case body connecting section  21   i  may be used to join a third case body conduit section (not illustrated) to the device  15 , so that the contents of a third duct (not illustrated) may also be transferred through the device  15 . Further, almost any suitable mechanism may be incorporated as a part of the case body connecting section  21   i.  For example, the case body connecting section  21   i  may incorporate flow meters, temperature sensors, pressure sensors, material composition sensors, alarms, and other devices, monitors and mechanisms. Further still, the case body connecting section  21   i  may have a different shape in other embodiments. For example, the case body connecting section  21   i  may have a different cross-sectional shape or may be longer or shorter than as illustrated in  FIG. 1 . 
     Continuing to refer to the device  15  illustrated in  FIG. 1  as an example, the case body connecting section  21   i  may be comprised of almost any suitable material or combination of materials depending upon the nature of the features incorporated as a part of the case body connecting section  21   i . In embodiments where mechanisms are incorporated, the case body connecting section  21   i  may be comprised of a suitable rigid or semi-rigid material to support the incorporated mechanism in operation of the device  15 . For example, the case body connecting section  21   i  may be comprised of metal (such as steel, steel alloys, aluminum, copper, brass, or other metals or metal alloys), polymers (such as PVC, polyethylene, polypropylene, ABS, and other polymers), wood, fiberglass, carbon-based or other composites, or other materials or a combination of such materials. In other embodiments, it may be preferred that the case body connecting section  21   i  be comprised of a flexible or semi-flexible material, so that the case body connecting section  21   i  may bend, but is rigid enough so that it doesn&#39;t collapse or become unduly constricted while being bent or in other operation of the device  15 . In such embodiments, the case body connecting section  21   i  may be comprised of rubber, synthetic rubber (including NEOPRENE), elastomers or other elastic polymers (such as silicone), or combinations of such materials, along with a combination that may including cloth, fabric, metal mesh, or other flexible or semi-flexible materials. In each case, the preferred material is dependent upon a number of different factors, such as the anticipated size, shape and type of the duct (pipe  70 ), the type of connection to be made to the duct (pipe  70 ), the size, shape, material composition and configuration of any incorporated mechanism, the anticipated operating or installation temperatures of the device  15 , the type of fluid carried by the duct (pipe  70 ), the desired wall thickness and weight of the case body  21 , the preferences of the user of the device  15 , and other factors. The case body connecting section  21   i  may be fabricated using any suitable means. For example, and referring to  FIG. 3 , a case body connecting section  121   i  constructed of PVC may be formed by injection molding and a case body connecting section  121   i  constructed of a metal alloy may be formed by metal injection molding. Referring again to  FIG. 1 , in the case of a device  15  designed for room temperature domestic use and capable of accommodating ducts (pipe  70 ) in the range of 1″ to ½″ nominal diameter, the case body connecting section  21   i  is preferably constructed primarily of PVC and has a ball valve mechanism incorporated as a part thereof with a passage diameter of approximately ½″. 
     In embodiments of the device  15  comprising case body conduit sections  21 ′,  21 ″ and a case body connecting section  21   i , case body section connecting means are used to permanently or removably connect the case body conduit sections  21 ′,  21 ″ to the case body connecting section  21   i . For example, as illustrated in  FIG. 2 , the case body section connecting means are comprised of threads  21   j ,  21   k  on the case body connecting section  21   i  and corresponding threads ( 21   l  for  21 ″, but not illustrated for  21 ′) on case body conduit sections  21 ′,  21 ″. Thus, the case body conduit sections  21 ′,  21 ″ and the case body connecting section  21   i  may be removeably connected together by screwing the case body conduit sections  21 ′,  21 ″ onto, and by unscrewing them from, the case body connecting section  21   i . Similarly, as illustrated in  FIG. 3 , the case body section connecting means are comprised of threads  121   j ,  121   k  on the case body connecting section  121   i  and corresponding threads ( 121   l  for  121 ″, but not illustrated for  121 ′) on case body conduit sections  121 ′,  121 ″. In embodiments where the threads  121   j ,  121   k  on the case body connecting section  121   i  are the same as the threads  21   j ,  21   k  on the case body connecting section  21   i  (as illustrated in  FIG. 2 ), which is the preferred embodiment, the user of the appliances  15 ,  115  may use the case body connecting sections  21   i ,  121   i  interchangeably with each of the devices  15 ,  115 . Thus, the device  15 ,  115  preferably incorporates a modularized system of interchangeable case body connecting sections  21   i  that may be used with the devices  15 ,  115  comprising the present invention. The modular system provides the user of the device  15 ,  115  with flexibility in that the user has the ability to use different case body connecting sections  21   i ,  121   i  incorporating different types of mechanisms, shapes and sizes when operating the device  15 ,  115  in different circumstances. In other embodiments, the case body section connecting means may take another form or forms. For example, as illustrated in  FIG. 4 , the case body section connecting means may take the forms of hose bard connectors  221   j ,  221   k  positioned on the ends of the case body connecting section  221   i , which are adapted to fit adjacent to the interior surfaces of the case body channel components  221   b ,  221   f , respectively. Referring again to  FIG. 1  as an example, in yet other embodiments, case body section connecting means for connecting the case body connecting section  21   i  to the case body conduit sections  21 ′,  21 ″ may be comprised of any appropriate means, such as clasps, clamps, clips, pins, hinges, adhesives, epoxies, welding, fusing, nails, screws, nuts, bolts, or other types of fasteners or connectors, either alone or in conjunction with one another in different combinations. In addition, the case body section connecting means may also comprise a sealing compound (such as pipe dope) or another sealing mechanism, such as TEFLON tape, or a combination thereof. Preferably, the case section connecting means are comprised of a modularized system of threads  21   j ,  21   k  on the case body connecting section  21   i  and corresponding threads ( 21   l  for  21 ″, but not illustrated for  21 ′) on the case body conduit sections  21 ′,  21 ″. 
     Continuing to refer to the device  15  illustrated in  FIG. 1  as an example, it is to be noted that the device  15  may be comprised of more than one case body connecting section  21   i . For example, if the case body channel component  21   b  and the case body channel component  121   b  (illustrated in  FIG. 3 ) are opposite ends of the same component, then the case body connecting section  21   i  and the case body connecting section  121   i  would be connected together in series between the case body conduit sections  21 ″,  121 ″. In this case, the interconnecting segment  21   b ,  121   b  would also be considered to be a case body conduit section, except that instead of having one end adapted to be connected to the adjusting connector member  30 , both ends would be adapted to be connected to the adjoining case body connecting sections  21   i ,  121   i . Conceivably, any number of such case body connecting sections  21   i ,  121   i  could be connected together in this manner. In addition, in embodiments where the case body connecting section  21   i  takes the form of a tee or a “Y” connector (not illustrated), one or more of the case body conduit sections  21 ′,  21 ″ may also be connected to a case body connecting section  21   i , so that, for example, each case body conduit section  21 ′,  21 ″ would have a valve mechanism to regulate the flow of fluid through such case body conduit sections  21 ′,  21 ″. Thus, there are many potential combinations of case body connecting sections  21   i ,  121   i  that may be connected together with case body conduit sections  21 ″,  121 ″. All of such combinations are within the spirit and scope of the present invention as defined by the appended claims. 
     Another embodiment of a casing member  320  is illustrated in the device  315  of  FIG. 5 , in which the case body  321  is comprised primarily of rigid or semi-rigid materials. Thus, the case body conduit sections  321 ′,  321 ″ (which comprise case body end components  321   a ,  321   e , respectively, but not case body channel components) may be comprised of a rigid or semi-rigid material, such as that comprising the case body end components  21   a ,  21   e , as described in more detail above and illustrated in connection with  FIG. 1 . In addition, case body section connecting means may be used to removably or permanently connect the case body conduit sections  321 ′,  321 ″ to the case body connecting section  321   i , which further comprises a valve mechanism in this embodiment. In other embodiments, the case body connecting section  321   i  may comprise substantially the same structure, features, characteristics, functions and operation as the case body connecting section  21   i  described in more detail above and illustrated in connection with  FIG. 1 . Preferably, the case body section connecting means are operatively the same as the case body section connecting means described above and illustrated in connection with  FIG. 1  so that both devices  15 ,  315  are part of a modular system combining different embodiments of case body conduit sections  21 ′,  21 ″,  321 ′,  321 ″ and case body connecting sections  21   i ,  321   i  that may be operatively connected together interchangeably. In other embodiments, the case body conduit sections  321 ′,  321 ″ and the case body connecting section  321   i  may be constructed as a single component. In the device  315  illustrated in  FIG. 5 , the case body  321  is further comprised of a swivel connector  321   m  positioned on each case body end component  321   a ,  321   e . Considering the case body end component  321   a  receiving the adjusting connector member  330  as an example, the swivel connector  321   m  is comprised of a sealing mechanism (not illustrated) that allows the portion  321   a ′ of the case body end component  321   a  adjacent to the adjusting connector member  330  to rotate relative to the remaining portions  321   a ″ of the case body end component  321 . Thus, in using the device  315 , the duct (not illustrated) and all portions of the casing member  320  except the portion  321   a ′ adjacent to the adjusting connector member  330  may be held stationary, while the portion  321   a ′ adjacent to the adjusting connector member  330  is rotated in order to connect the device  315  to the duct. To assist in this type of operation, the device  315  may be further comprised of case body tab portions  321   n ,  322   c ,  323   c  that may be used to rotate the various components comprising the device  315  relative to one another. In other embodiments, the case body tab portions  321   n ,  322   c ,  323   c  may not be present or may take another form, shape or configuration. Swivel connectors  321   m  of the type utilized in the device  315  are well known in the relevant art. In other embodiments, the swivel connector  321   m  may comprise any other type of swivel connector  321   m  currently known in the relevant art or that may be developed in the relevant art in the future. For example, rather than allowing the adjoining portions  321   a ′,  321   a ″ to rotate only circumferentially, the swivel connector  321   m  may allow the adjoining portions  321   a ′,  321   a ″ to move in almost any direction relative to one another. 
     Yet another embodiment of a casing member  420  is illustrated in  FIG. 6  and  FIG. 7 .  FIG. 7  illustrates the case body  421  of the device  415  illustrated in  FIG. 6 , showing hidden lines of the case body  421  in phantom. In this embodiment, the casing member  420  does not have a case body connecting section similar to that  21   i  illustrated in  FIG. 1 . Instead, the casing member  420  is comprised of two case body end sections  421   a ,  421   e  that are connected together by a case body conduit section  421   b . Preferably, the case body conduit section  421   b  is comprised of any flexible material that may comprise the case body channel components  21   b ,  21   f  described in more detail above and illustrated in connection with  FIG. 1 . In this embodiment, the casing member  420  may be bent into a U-shape during its operation. Thus, it is possible to connect the adjusting connector member  430  of the device  415  to a first container spout (not illustrated) while the first container is resting on a surface (such as a table or counter top). The spout of a second container (also not illustrated) may then be connected to the other adjusting connector member  440  while the second container is also resting on the same surface without the need to move the first container. 
     In the embodiment of the device  15  illustrated in  FIG. 1 , the case caps  22 ,  23  are approximately cylindrical in shape and may be permanently or removably attached to the open ends  21   c ,  21   g  of the case body  21  adjacent to the case caps  22 ,  23  by the case cap connecting means, which are described in more detail below. Considering the case cap  22  as an example, the case cap connecting means are comprised of threads  21   d  on the outside surface of the portion of the case body  21  adjacent to the open end  21   c  of the case body  21  and corresponding threads  22   b  on the interior surface of the tubular portion of the case cap  22 . Thus, the case cap  22  may be placed over the open end  21   c  of the case body  21 , and may then be screwed down onto the case body  21 . In this embodiment, when the case cap  22  is screwed down onto the case body  21 , a portion of the adjusting connector member  30  is compressed between the case cap  22  and the case body  21 , holding the adjusting connector member  30  in place relative to the casing member  20  and forming a fluid-tight seal between the adjusting connector member  30  and the case body  21 , all as described in more detail below. In other embodiments, the threads  21   d ,  22   b  may be oriented in a different configuration. For example, the threads  21   d  on the case body  21  may be positioned on the interior surface of the case body  21 , and the corresponding threads  22   b  of the case cap  22  may be positioned on the exterior surface of a disc-shaped case cap  22 . In this embodiment, the case cap  22  is screwed into the case body  21 , holding the adjusting connector member  30  in place relative to the casing member  20  and forming a fluid-tight seal between the adjusting connector member  30  and the case body  21  in a manner similar to that described above. 
     In other embodiments, the case cap  22  may have a different shape, as long as the case cap  22  cooperates with the case body  21  and the adjusting connector member  30  to accommodate the operation of the device  15 , as described in more detail herein. For example, the case cap  22  may facilitate a fluid-tight seal between the case body  21  and the adjusting connector member  30  in this embodiment, as described in more detail below. In addition, the connector opening  22   a  may be of almost any size and shape, as long as it cooperates with the casing connecting means (described in more detail below) in connecting the adjusting connector member  30  to the case body  21  and permitting the adjusting connector member  30  to be connected to the duct (pipe  70 ), which means that the duct (pipe  70 ) may be inserted into the casing member  20  and the adjusting connector member  30  in this embodiment. The connector opening  22   a  is generally of a size and shape adapted to have the duct (pipe  70 ) positioned within the connector opening  22   a . The case cap  22  may generally be comprised of any materials or combinations of materials that may be used to construct the case body  21 , as described in more detail above and illustrated in connection with  FIG. 1 . Although the case cap  22  need not be constructed of the same material as the case body  21 , the case cap  22  is preferably constructed of the same material comprising the case body end component  21   a , as described in more detail above. The case cap  22  may be fabricated using any suitable manufacturing means. For example, a case cap  22  comprised of PVC may be formed by injection molding and a case cap  22  comprised of a metal or metal alloy may be formed by metal injection molding. In some embodiments, as illustrated in  FIG. 6 , the case caps  422 ,  423  may have protruding ridges on the exterior surface thereof that assist the user in gripping the case cap  422 ,  423 , particularly when the case cap  422 ,  423  is being screwed onto or off of the case body  421  or when the duct is being connected to the device  415 . 
     In addition, and referring again to the embodiment of the present invention illustrated in  FIG. 1 , the case cap connecting means may be comprised of means other than the illustrated threads  21   d ,  22   b , as long as they cooperate with the casing connecting means (described in more detail below) in connecting the adjusting connector member  30  to the case body  21  and are adapted to cooperate with the adjusting connector member  30  in operation of the device  15 , all as described in more detail below. In the illustrated embodiment, such operation means, among other things, that the case cap connecting means permit the connector opening  22   a  to be of a size and shape adapted to receive the duct (pipe  70 ). For example, other case cap connecting means that may be used to removably connect the case cap  22  to the case body  21  comprise clasps, clamps, clips, pins, hinges, other pivoting connectors or other types of connectors, either alone or in conjunction with one another in different combinations. Examples of case cap connecting means that may be used to permanently connect the case cap  22  to the case body  21  include adhesives, epoxies, welding, fusing, nails, screws, nuts, bolts, or other fasteners or a combination of such means. Where the adjusting connector member  30  may be positioned within the interior space  20   a  of the casing member  20  other than through the open end  21   c  of the case body  21 , the case cap  22  may also be fabricated as a part of the case body  21 . It is to be noted, however, that the case cap connecting means may or may not be utilized to facilitate a fluid-tight seal between the adjusting connector member  30  and the case body  21 . In some embodiments, a fluid-tight seal may be inherent in the type of case cap connecting means used (such as welding or fusing), or it may be created in whole or in part by the casing connecting means (as described in more detail below) or additional sealing means, such as o-rings, gaskets, flanges, washers, or other similar types of means or combinations of such means, as described in more detail below. The preferred characteristics of the case cap  22  and case cap connecting means are dependent upon a number of different factors, such as the anticipated range of shapes and sizes of the duct (pipe  70 ), the size, shape, material composition and configuration of the adjusting connector member  30 , the type of casing connecting means (which are described in more detail below), the anticipated operating pressures of the device  15 , the materials comprising and the shape of the case body  21 , the preferences of the user of the device  15 , and other factors. More preferred, the case cap  22  is generally of the shape illustrated in  FIG. 1  and has the illustrated threaded case cap connecting means. It is to be noted that the case cap  23  may have substantially the same structure, features, characteristics, functions and operation as the case cap  22  described above and illustrated in connection with  FIG. 1 . The case cap  23  may be permanently or removably connected to the case body  21  at the case body open end  21   g  using case cap connecting means (threads  21   h ,  23   b ) and may cooperate with the adjusting connector member  40  in substantially the same manner as described above for case cap  22  and its associated adjusting connector member  30 . 
     In some embodiments, as illustrated in  FIG. 8A  through  FIG. 8B , the case cap  522  is further comprised of duct holding means adapted for holding the duct (not illustrated) in place relative to the device (not illustrated). In this embodiment, the case cap  522  may generally have substantially the same structure, features, characteristics, functions, and operation as the case caps  22 ,  23  described in more detail above and illustrated in connection with  FIG. 1 , except that the case cap  522  may have a greater length in the longitudinal direction of the case body (not illustrated) in order to accommodate the duct holding means. The case cap  522  is connected to the case body using case cap connecting means, which comprise the threads  522   b  in this embodiment. In this embodiment, the duct holding means are comprised of a plurality of duct support members  522   e ,  522   f ,  522   g  extending away from the casing member (case cap  522  in this embodiment), which are further comprised of holder brackets  522   e , release tabs  522   f , and holder supports  522   g . Each holder support  522   g  is further comprised of a bracket connector  522   g   1 , a support arm  522   g   2 , and a support brace  522   g   3 . The holder brackets  522   e  are positioned on the outside surface of the case cap body  522   d . Each bracket connector  522   g   1  is positioned within a holder bracket  522   e  and is held in place there by a pin, dowel, bolt or other pivoting fastener so that the bracket connector  522   g   1  is free to pivot within the holder bracket  522   e . Each bracket connector  522   g   1  also has a series of ratchet-type teeth around its outside surface. Each release tab  522   f  is an approximately U-shaped tab that is generally cut into the surface of the case cap body  522   d . On the end of each release tab  522   f , there is a protruding ridge (not illustrated) that is adapted to engage the teeth on the exterior surface of the bracket connector  522   g   1 . The protruding ridge works in conjunction with the bracket connector  522   g   1  in a ratchet-type manner, as described in more detail below. The bracket connector  522   g   1  is connected to the support arm  522   g   2 . In this embodiment, the support arm  522   g   2  is further comprised of two telescoping support arm members  522   g   2 ′,  522   g   2 ″. Thus, the support arm member  522   g   2 ″ may be retracted into the support arm member  522   g   2 ′ as desired to store the duct holding means when not in use or to adapt such means to hold ducts (or objects) of varying size and shape. A support brace  522   g   3  is attached to each support arm  522   g   2  at the distal end of the support arm  522   g   2 . The support braces  522   g   3  and the support arms  522   g   2  are together adapted to engage the duct (or an object of which the duct is a part, such as a bottle or another container) in a manner so that the duct is held in place by the support brace  522   g   3  and the support arm  522   g   2 . One or more of the support braces  522   g   3  or the support arms  522   g   2  or both may have a layer of a material having a relatively high level of tackiness on the surfaces facing the duct in order to assist the holder supports  522   g   3  in holding the duct in place. Support braces  522   g   3  need not be present or may have a different shape, size or configuration in different embodiments of the duct holding means. 
     In operation of the embodiment of the case cap  522  illustrated in  FIG. 8A  through  FIG. 8B , the holder supports  522   g  may be retracted against the case cap body  522   d  when not in use, as illustrated in  FIG. 8B . When the user of the device desires to use the duct support members ( 522   d  through  522   g   3  in this embodiment), the user may lift the holder support  522   g  away from the case cap body  522   d . As this happens, the teeth on the bracket connector  522   g   1  slide past the protruding ridge portion of the release tab  522   f  as the bracket connector  522   g   1  rotates within the support bracket  522   e . The user may also extend the support arm  522   g   2  by pulling on the support arm member  522   g   2 ″ so that it telescopes out from the support arm member  522   g   2 ′ the desired distance to engage the duct. The holder support  522   g  is moved until it is in the desire position relative to the duct, at which point the teeth of the bracket connector  522   g   1  engage the protruding ridge on the release tab  522   f , so that the holder support  522   g  cannot move back in the direction of the outside surface of the case cap body  522   d . Considering a bottle with a spout that comprises the duct as an example (not illustrated), the three holder supports  522   g  are fully or partially extended, as illustrated in  FIG. 8A , so that they are positioned against the outside surface of the bottle in a manner that operatively holds the bottle tightly against the surfaces of the support braces  522   g   3  or the support arms  522   g   2  or both. When the user no longer needs the duct support members ( 522   d  through  522   g   3  in this embodiment), he or she may press down on the tab releases  522   f  (from the outside surface of the case cap body  522   d ), which causes the protruding ridge of the release tabs  522   f  to disengage from the teeth on the bracket connectors  522   g   1 . This allows the bracket connectors  522   g   1  to rotate within the support brackets  522   e  (as long as the release tabs  522   f  are being depressed) in a manner that permits the holder supports  522   g  to be retracted back against the outside surface of the case cap body  522   d.    
     It is to be noted that there are many potential variations on the duct holding means. For example, and referring to  FIG. 8A  through  FIG. 8C  as an example, there may be more or fewer holder supports  522   g  in other embodiments. In addition, some or all of the support arms  522   g   2  may not have a telescoping feature. Further, the holder supports  522   g  may have a different size, shape or configuration in other embodiments. For example, the support arms  522   g   2  may have a greater or lesser angle of curvature or a longer or shorter length (or both) depending upon the size of ducts (or other objects) that are anticipated for use with the duct holding means. In fact, various embodiments of the duct holding means may be comprised of various members having almost any combination of size, shape, and configuration depending upon the nature of the anticipated use of the duct holding means. Further still, the means of connecting the holder supports  522   g  to the case cap body  522   d  may be different than in the illustrated embodiment. For example, the connecting means may comprise a support bracket  522   e , but the bracket connector  522   g   1  may be held in place in the support bracket  522   e  by a bolt with a wing nut that compresses the sides of the support bracket  522   e  against the bracket connector  522   g   1 . Almost any type of suitable fastening means currently known in the relevant art or that may be developed in the relevant art in the future may be used to make this connection, such as clamps, clips, nuts, bolts, screws, dowels, pins, or other fastening means or a combination of such means. In the embodiment of the case cap  522  illustrated in  FIG. 8A  through  FIG. 8C , the support bracket  522   e  and the release tab  522   f  are preferably constructed of the same material as the case cap body  522   d  (and the same as material as the case caps  22 ,  23 , as described in more detail above and illustrated in connection with  FIG. 1 ), but this need not be so in every embodiment. The holder supports  522   g  are also preferably constructed entirely of the same material, but this need not be so in every embodiment. The holder supports  522   g  may be constructed of any suitable rigid or semi-rigid material. Examples include metal (such as steel, steel alloys, aluminum, copper, brass, or other metals or metal alloys), polymers (such as PVC, polyethylene, polypropylene, ABS, and other polymers), wood, fiberglass, carbon-based or other composites, or other materials or a combination of such materials. In the illustrated embodiment, the holder supports  522   g  are preferably comprised entirely of a rigid polymer material, such as PVC or ABS. The case cap  522  may be constructed using any suitable means, such as injection molding for a case cap body (including support brackets  522   e  and release tabs  522   f ) and holder supports  522   g  constructed of PVC. Where any of such components are assembled from subcomponents, suitable connecting means may be used in the assembly process, such as adhesive, glue, epoxy, welding, fusing, clamps, clips, or other fastening means or a combination of such means. 
     In other embodiments, the duct holding means may take an entirely different form, as illustrated in the case cap  622  of  FIG. 9 . In this embodiment, the case cap  622  may generally have substantially the same structure, features, characteristics, functions, and operation as the case caps  22 ,  23  described in more detail above and illustrated in connection with  FIG. 1 , except that the case cap  622  may have a greater length in the longitudinal direction of the case body (not illustrated) in order to accommodate the duct holding means. The case cap  622  is also adapted to be connected to a case body (not illustrated) using case cap connecting means (threads  622   b ), as described above and illustrated in connection with  FIG. 1 . In this embodiment, the duct holding means are comprised of a plurality of duct support members  622   g  extending away from the casing member (case cap  622  in this embodiment), which are further comprised of holder supports  622   g  that are rigidly connected to the case cap body  622   d . The holder supports  622   g  are comprised of a material or materials that allows them to flex, but only with a considerable amount of force being exerted against them to do so. Thus, in this embodiment, the user of the case cap  622  may exert pressure against the holder supports  622   g  in order to bend them until they rest against the duct (or other object). Once the pressure is released from the holder supports  622   g , they tend to retain that position until a relatively substantial force is applied to move them. Generally, this force is cumulatively greater than the force that is anticipated to be necessary to operatively hold the duct in place relative to the case cap  622  by the holder supports  622   g . In various embodiments, the holder supports  622   g  may have almost any combination of sizes, shapes, and configurations depending upon the nature of their anticipated use. In this embodiment, the holder supports  622   g  may be constructed of any materials that permit the holder supports  622   g  to operate as intended. For example, the holder supports  622   g  may be constructed entirely of a semi-rigid polymer or metal or metal alloy. As another example, the holder supports  622   g  may be comprised of a length of metal or metal alloy cable that is encased within a semi-rigid polymer. Examples of other materials include metal (such as steel, steel alloys, aluminum, copper, brass, or other metals or metal alloys), polymers (such as PVC, polyethylene, polypropylene, ABS, and other polymers), wood, fiberglass, carbon-based or other composites, or other semi-rigid materials or a combination of such materials. In the illustrated embodiment, the holder supports  622   g  are preferably comprised entirely of a semi-rigid polymer material. The case cap  622  may be constructed using any suitable means used to construct the case caps  22 ,  23 , as described in more detail above and illustrated in connection with  FIG. 1 . Holder supports  622   g  constructed of a semi-rigid polymer may be constructed by injection molding. Where the case cap body  622   d  and the holder supports  622   g  are fabricated separately, they may be assembled using any suitable connecting means, such as adhesive, glue, epoxy, welding, fusing, clamps, clips, or other fastening means or a combination of such means. Referring to the device  715  illustrated in  FIG. 10 , although the duct holding means may be incorporated as a part of the case body  721 , rather than the case cap  722 , the duct sealing means are preferably incorporated as a part of the case cap  522 ,  622 , as described in more detail above and illustrated in connection with  FIG. 8A  through  FIG. 9 , because this provides the user of the device with the choice as to whether to have the duct sealing means present or not in operation of the device. 
     Yet another embodiment of a casing member  720  is illustrated in the device  715  of  FIG. 10 . This embodiment illustrates that the duct holding means (duct holder supports  721   o  in this embodiment) may also be incorporated as a part of the case body  721 , rather than the case cap  722 . In various embodiments, the duct holding means (duct holder supports  721   o ) incorporated as a part of the case body  721  may comprise any of the duct holding means described above and illustrated in connection with  FIG. 8A  through  FIG. 9 , as long as the duct holding means (duct holder supports  721   o ) do not unduly interfere with the operation of the device  715 . Although the illustrated positioning of the duct holding means (duct holder supports  721   o ) on the case body end component  721   a  is the preferred positioning, the duct holding means (duct holder supports  721   o ) may be positioned on other portions of the case body  721  in other embodiments. The embodiment of the device  715  of  FIG. 10  also illustrates that the casing member  720  need not be comprised solely of openings adapted for receiving adjusting connector members (such as adjusting connector member  730 ). In such embodiments, the casing member  720  may be further comprised of an object open end  723   a  and object connecting means (MIP adapter  723  in this embodiment) that are used to connect an object (not illustrated) to the casing member  720  at the object open end  723   a . The object may generally comprise any of the structures, features, characteristics, functions and operation of the ducts (pipes  70 ,  870  and bottle spout  875   a ) described in more detail herein and illustrated in connection with  FIG. 19 . In addition, the object may be comprised in whole or in part of equipment, machinery, containers, tanks, or other objects or a combination of such objects to which it may be desirable to connect one or more ducts in a manner that provides for fluid communication between the interior space of the object with the interior space of the duct, as described in more detail below. In the embodiment of the device  715  illustrated in  FIG. 10 , the object connecting means are comprised of a male iron pipe (MIP) adapter  723  fabricated as a part of, and positioned at one end of, a case body  721 . Also, in this embodiment, the MIP adapter  723  is positioned on the case body  721  so that the longitudinal axis of the MIP adapter  723  is collinear with the longitudinal axis of the case body  721 . In other embodiments, the MIP adapter  723  (or other object connecting means) may be positioned on a different portion of the case body  721  or have a different orientation relative to the case body  721 , as long as the position does not adversely affect the operation of the device  715 , as described in more detail herein. For example, the MIP adapter  723  may extend from the sidewall of the case body  721  (as opposed to from the end of the case body  721 ) and may be oriented at a 45 degree angle relative to the longitudinal axis of the case body  721 . In the illustrated embodiment, the MIP adapter  723  may be fabricated as a part of the case body  721 , which is the preferred means of fabrication, or it may be fabricated separately from the case body  721  and attached to the case body  721  by any suitable means, such as adhesives, epoxies, welding, fusing, nails, screws, clips, clamps, nuts, bolts, or other fasteners or a combination of such means. 
     Referring to the embodiment of the device  715  illustrated in  FIG. 10  as an example, the object connecting means (MIP adapter  723 ) may be comprised of almost any suitable means, and preferably means that may be used for making a fluid-tight connection. For example, the object connecting means may be comprised of a female iron pipe (FIP) adapter. As other examples, the object connecting means may be comprised of welding, fusing, adhesives, glues, epoxies, a garden hose connector, a connector having any type of the threads (male or female), luer lock fittings, SWAGELOK® fittings, quick connect/disconnect fittings, hose barbs, stepped tubing connectors, bushings, flanges, compression fittings, tubing and hose connectors, SPEEDFIT® connectors, couplings for connection using clamps or adhesives, or other means or a combination of such means. In addition, the object connecting means may be comprised in whole or in part of a segment of conduit, tubing (including medical or food grade tubing), pipeline, duct, hose, channel, vent, a spout or other outlet or inlet member, or other similar objects or a combination of such objects extending from a portion of the casing member  720 . The preferred object connecting means for use with any particular embodiment of the device  715  depends upon a number of factors, such as the anticipated size, shape and type of materials comprising the object, the anticipated operating pressures of the device  715 , the anticipated operating or installation temperatures of the device  715 , the materials comprising and the shape and size of the casing member  720 , the preferences of the user of the device  715 , and other factors. More preferably, for an MIP adapter  723  comprised of PVC that is used to connect a pipe (not illustrated), the MIP adapter  723  is positioned and oriented as illustrated in  FIG. 10  and is fabricated as a part of the case body  721  by injection molding. 
     Continuing to refer to  FIG. 10 , the object connecting means may also be used to connect the casing member  720  to the side wall of another pipe. Further, the object connecting means may also be comprised in whole or in part of another adjustable connecting means (which are described in more detail below) of the present invention. Further still, the object connecting means may be comprised in whole or in part of the object, such as a tank, container, machine or item of equipment or any portion of the same. For example, the object connecting means may be comprised of the case body  721  being a part of or affixed to the side wall of a tank (not illustrated), so that the device  715  connects a duct (not illustrated) to the interior space of the tank (which would comprise the object in this embodiment). As another example, the case body  721  may be a part of or affixed to a panel on a piece of machinery or equipment (panel  750  in the illustrated embodiment), so that the device  715  connects the duct to the portion of the machinery that utilizes fluid supplied by the duct. An embodiment of this type of connection is illustrated in  FIG. 10 , in which another object connecting means of the device  715  is comprised of a collar member  721   p  that extends around the circumference of the case base  721  at the case body end component  721   e . In this embodiment, the equipment panel or the boundary wall of a container  750  has an opening  750   a  therein. The case body  721  is inserted into the opening  750   a  in the panel or boundary wall  750  until it abuts up against the collar member  721   p . In this embodiment, the panel or boundary wall  750  and a washer  721   r  are held in place against the collar member  721   p  by a lock nut  721   s . The lock nut  721   s  has threads  721   s ′ that correspond to threads  721   q  on the case body  721  adjacent to the collar member  721   p , so that the lock nut  721   s  is screwed down onto the case body  721  threads  721   q  until the panel or boundary wall  750  and the washer  721   r  are held tightly between the collar member  721   p  and the lock nut  721   s . In other embodiments, the panel or boundary wall  750  may be held in place against the collar member  721   p  by any suitable means, such as clasps, clamps, clips, pins, dowels, adhesives, epoxies, welding, fusing, nails, screws, nuts, bolts, flanges or other means or a combination thereof. Alternatively, the case body  721  and the panel or boundary wall  750  may be fabricated together as a single component. The washer  721   r , which assists in forming a fluid-tight seal between the panel wall  750  and the case body  721 , need not be present in all embodiments of the present invention. 
     Generally, and referring to the device  15  illustrated in  FIG. 1  and in  FIG. 11A  through  FIG. 12C  as an example, the at least one adjusting connector member (adjusting connector member  30 ) is capable of connecting to ducts (pipe  70 ) that have a different range of sizes and shapes (relatively larger ducts) than the range of sizes and shapes of ducts (not illustrated, but relatively smaller ducts) that may be connected to the at least one additional adjusting connector member (adjusting connector member  40 ). Considering adjusting connector member  30  as an example for purposes of the present description, the adjusting connector member  30  (as adjustable connecting means in this embodiment) of the device  15  is positioned approximately within the open end  21   c  of the case body  21 . By positioning “approximately within the case body open end  21   c ,” it is meant that the adjusting connector member  30  is generally intended to be positioned adjacent to and within the space bounded by the portion of the case body  21  adjacent to the case body open end  21   c , but that in some embodiments the adjusting connector member  30  may be positioned slightly above or below or within such case body adjacent portion or that there may be other members, such as a washer (not illustrated), also placed in the case body open end  21   c  so that the adjusting connector member  30  may be slightly displaced from the case body open end  2   c . As described in more detail below and illustrated in connection with  FIG. 19 , the end of the duct (pipe  70 ) is inserted into the device  15 , so that the duct (pipe  70 ) extends into the adjusting connector member  30  as well. As is also illustrated in  FIG. 11A  through  FIG. 11C , the at least one adjusting connector member (adjusting connector member  30 ) is further comprised of duct sealing means (duct seal member  31  in this embodiment), seal bracing means (bracing member  32  in this embodiment), thread engaging means (thread engaging member  33  in this embodiment), adjusting member internal connecting means for operatively connecting the sealing means (duct seal member  31 ), the seal bracing means (bracing member  32 ), or the thread engaging means (thread engaging member  33 ) or all of them together in various embodiments, and casing connecting means for connecting the at least one adjusting connector member (adjusting connector member  30 ) to the casing member  20 , all of which are described in more detail below. 
     In the embodiment of the adjusting connector member  30  illustrated in  FIG. 11A  through  FIG. 11C , the duct sealing means are adapted to conform to the shape of and adhere to the exterior surface of the duct (pipe  70 ) while the duct (pipe  70 ) is inserted into the adjusting connector member  30  (and the device  15  of  FIG. 1 ), preferably forming a fluid tight seal between the duct (pipe  70 ) and the adjusting connecting means (adjusting connector member  30  in this embodiment). In the illustrated embodiment, the duct sealing means are generally comprised of a duct seal member  31 , which is further comprised of an inlet seal flange portion  31   a , a seal sheath portion  31   b  that extends from the seal flange portion  31   a , and an outlet seal flange portion  31   c  that is positioned at the distal end of the seal sheath portion  31   b . The duct seal member  31  is further comprised of a seal interior surface  31   d  and a seal exterior surface  32   e . The seal sheath portion  31   b  also has a plurality of holes  31   f  positioned therein, which cooperate with the thread engaging member  33 , as described in more detail below. In the illustrated embodiment, the duct seal member  31  is generally shaped as an hourglass, which also means that at least a portion of the duct seal member  31  is approximately shaped as a hyperboloid. In other embodiments, the duct sealing means (duct seal member  31  in the illustrated embodiment) may have a different shape, size or configuration. For example, as illustrated in  FIG. 13 , the duct seal member  61  may have an approximately hyperboloid shape, as described in more detail below. As another example, the duct seal member  461 ,  464  illustrated in  FIG. 17A  and  FIG. 17B  may have an approximately hyperboloid shape and may be comprised of two components  461 ,  464 , as described in more detail below and illustrated in connection with  FIG. 17A  and  FIG. 17B . In various embodiments, the duct seal member  31  may have any size, shape or configuration suitable to fulfill an intended function of being positioned adjacent to the exterior surface of the duct (pipe  70 ) while the duct (pipe  70 ) is operatively connected to the device  15 . 
     The duct sealing means (duct seal member  31 ) are generally constructed in whole or in part of materials that permit them to change shape (typically expanding) to conform to the exterior surface of the largest size of duct (pipe  70 ) that may be connected to the duct seal member  31 , while still maintaining the structural integrity of the duct seal member  31  during operation of the device  15 . In addition, the materials are preferably compatible with the type of fluid anticipated to be carried by the duct (pipe  70 ). For example, the duct seal member  31  may be comprised of any suitable elastic material, such as rubber, synthetic rubber (including NEOPRENE), elastomers or other elastic polymers, or combinations of such materials, along with a combination that may including cloth, fabric or other flexible or semi-flexible materials. It is to be noted, however, that the duct seal member  31  need not be constructed entirely of flexible or elastic materials. For example, all or a portion of the inlet seal flange portion  31   a , or another portion of the duct seal member  31 , or any combination thereof, may be comprised of a rigid or semi-rigid material, such as wood, ceramic, metal, fiberglass, carbon-based or other composites, rigid or semi-rigid polymers (such as polyvinyl chloride and polycarbonate), or other rigid or semi-rigid materials or a combination of such materials. This may assist in facilitating a fluid-tight seal between the inlet seal flange portion  31   a , the thread engaging member  33 , the bracing member  32 , the case body  21  or a combination thereof in some embodiments. The duct seal member  31  may be constructed using any suitable means. For example, a duct seal member  31  constructed entirely of synthetic rubber may be cast in a mold. As another example, a duct seal member  31  comprised of one or more materials may have various components assembled utilizing adhesives, welding, fusing or any other suitable means. Preferably, for devices  15  utilizing the duct seal member  31  of the illustrated embodiment and designed for use with tubular ducts (pipe  70 ) having a nominal diameter in the range of ½″ to ¾″ carrying potable water for domestic use, the duct seal member  31  has the configuration illustrated in  FIG. 11A  through  FIG. 11C  and is constructed entirely of NEOPRENE having a thickness in the range of 1/16 inch to ⅛ inch. It is also to be noted that in various embodiments of the present invention, the duct sealing means may have any structure, characteristics, features, functions, and operation disclosed for the sealing member and its ancillary members in U.S. patent application Ser. No. 11/879,346 filed on Jul. 17, 2007, Ser. No. 12/012,954 filed on Feb. 6, 2008, and U.S. Provisional Patent Application No. 61/062,428 filed on Jan. 25, 2008, and No. 61/066,258, entitled MODULAR COUPLING SYSTEM filed on Feb. 19, 2008. The full disclosure of each of these patent applications is incorporated herein by this reference. 
     As is best illustrated in  FIG. 11A  through  FIG. 11C , the bracing means are adapted to (among other things) allow a portion of the duct seal member  31  (as duct sealing means) to change shape to conform to the shape of the exterior surface of the duct (pipe  70 ) at the end thereof, while the bracing means may also provide structural support to assist in holding the duct (pipe  70 ), the duct sealing means (duct seal member  31 ), and the thread engaging means (thread engaging member  33 ) operatively in place relative to one another and, in some embodiments, the casing member  20 , all as described in more detail below. In the illustrated embodiment, the bracing means are comprised of a bracing member  32  having a brace inlet open end  32   a  and a brace outlet open end  32   b . Also in the illustrated embodiment, the bracing member  32  is a tubular-shaped shell that is connected to the thread engaging member  33  and the duct seal member  31  by the adjusting member internal connecting means, which are described in more detail below. At least a portion of the bracing member  32  may be positioned approximately adjacent to the duct seal member  31 . By “approximately adjacent,” it is meant that the bracing member  32  is intended to be positioned directly or indirectly adjacent to the duct seal member  32 , but that other members (such as washers, gaskets, or the thread engaging member  33  in the illustrated embodiment) may be positioned between them. The bracing member  32  may have a different size and shape in other embodiments of the present invention. For example, where the case base  21  has a hexagonal cross-section, it may be necessary or desirable for the bracing member  32  to be hexagonal to facilitate its connection to the case base  21 . The bracing member  32  may also be of a different shape as necessary to permit its operable connection to the duct seal member  31  or the thread engaging member  33  or both. As another example, the bracing member  32  may have one or more channels, openings, or other protrusions that are a part thereof. As yet another example, as described in more detail below and illustrated in connection with  FIG. 13 , the bracing member  62  may be combined with the thread engaging means  62   a ′. Referring again to  FIG. 11A  through  FIG. 11C , and as described in more detail below, the bracing member  32 , the duct seal member  31 , and the thread engaging member  33  preferably cooperate to form a fluid-tight seal between one another and the case body  21  (see  FIG. 1 ). The bracing member  32  may be constructed of any suitable material, preferably so it is capable of performing its functions of allowing a portion of the duct seal member  31  (as duct sealing means) to change shape to conform to the shape of the exterior surface of the duct (pipe  70 ) at the end thereof, while also providing structural support to assist in holding the duct (pipe  70 ), the duct sealing means (duct seal member  31 ), or the thread engaging means (thread engaging member  33 ), or any combination thereof, in place relative to one another and the casing member  20 , all as desired and as described in more detail below. Preferably, the bracing member  32  is comprised of a rigid or semi-rigid material, such as metal (e.g., spring steel, copper, brass, aluminum, another steel, or steel or metal alloy), wood, ceramic, fiberglass, carbon-based or other composites, rigid or semi-rigid polymers (such as PVC, NYLON or NYLON/glass combination, and polycarbonate), or other rigid or semi-rigid materials or a combination of such materials. In addition, it is preferred that the material comprising the bracing member  32  be compatible with the fluid carried by the duct (pipe  70 ). The bracing member  32  may be constructed using any suitable means. For example, a bracing member  32  constructed entirely of PVC may be formed by injection molding. The bracing member  32  is preferably fabricated of one material as a single component. Alternatively, the bracing member  32  may be constructed of more than one component or of different materials or a combination of materials, which may be connected to one another by a suitable joining means, such as an adhesive, adhesive tape, glue, epoxy, welding, fusing, brazing, or other joining means or a combination of such means. 
     In the embodiment of the device  15  illustrated in  FIG. 1 , and as best illustrated in  FIG. 11A  through  FIG. 11C , the thread engaging means are generally comprised of a thread engaging member  33 . In addition to performing other functions, the thread engaging means (thread engaging member  33  in this embodiment) allow a portion of the duct sealing means (duct seal member  31 ) to change shape to conform to the shape of the exterior surface at the end of the duct (pipe  70 ), while also engaging any threads  70   a  on the exterior surface of the duct (pipe  70 ), which also may assist in holding the duct (pipe  70 ), the duct sealing means (duct seal member  31 ), and the bracing means (bracing member  32 ) in place relative to one another and the casing member  20 , all as described in more detail below. In the illustrated embodiment, the thread engaging member  33  is comprised of a thread engaging flange member  33   a  and at least one thread engaging tab member  33   b  that extend from the interior perimeter of the thread engaging flange member  33   a  into the vicinity of the exterior surface  31   e  of the duct seal member  31 . By “into the vicinity of the exterior surface  31   e  of the duct seal member  31 ,” it is meant that the at least one thread engaging tab member  33   b  may be positioned adjacent to the exterior surface  31   e  of the duct seal member  31  or may be positioned so that all or a portion of the at least one thread engaging tab member  33   b  is not adjacent to the duct seal member  31 , as long as at least one thread engaging tab member  33   b  is close enough to such exterior surface  31   e  so that a portion of the at least one thread engaging tab member  33   b  extends through the duct seal member  31  enough so that such extending portion is adapted to engage any threads on the duct (pipe  70 ), as described in more detail below. Portions of the thread engaging tab members  33   b  extend through openings  31   f  in the duct seal member  31 . Thus, as the duct (pipe  70 ) is inserted into the device  15  (and the adjusting connector member  30 ), the threads  70   a  on the duct (pipe  70 ) engage the portions of the thread engaging tab members  33   b  that extend through the openings  31   f  of the duct seal member  31 . After initially engaging the thread engaging tab members  33   b , the duct (pipe  70 ) may be twisted or rotated as it continues to be inserted into the adjusting connector member  30 . This twisting or rotating motion, accompanied by the thread engagement between the threads  70   a  and the thread engaging tab members  33   b , may cause the duct (pipe  70 ) to be drawn down into the duct seal member  31 . The thread engaging means may also tend to assist in operatively holding the duct (pipe  70 ) in place in the duct seal member  31  once the duct (pipe  70 ) insertion is complete. Preferably, there is an approximately fluid-tight seal formed between the portions of the thread engaging members  33   b  that extend through the openings  31   f  in the duct seal member  31  and such openings  31   f . It is to be noted that the seal need not be completely fluid-tight in every embodiment, as described in more detail below. This approximately fluid-tight seal may be accomplished by a relatively tight fit between each of such portions  33   b  and its corresponding opening  31   f , or it may be accomplished by means of an adhesive, adhesive tape, epoxy, welding, fusing, clamps, clips, or other fastening or joining means or a combination of such means. 
     The thread engaging member  33  may have a different size and shape in other embodiments of the present invention. For example, where the case base  21  has a hexagonal cross-section, it may be necessary or desirable for the thread engaging flange member  33   a  to be hexagonal as well to facilitate the connection of the adjusting connector member  30  to the casing member  20 . As another example, the thread engaging tab members  33   b  may have a different shape than that illustrated, which shape may allow them to conform to a different shape of opening  31   f  in the duct seal member  31 . In other embodiments, there may be more or fewer thread engaging tab members  31   b  (rather than the three illustrated) or the thread engaging tab members  31   b  may have more or fewer portions extending through the openings  31   f  in the duct seal member  31 , or both. For example, as illustrated in  FIG. 12A  through  FIG. 12B , each thread engaging tab member  43   b  has three portions extending through the openings  41   f  in the duct seal member  41 , as compared to four portions for each thread engaging tab member  33   b  in the embodiment illustrated in  FIG. 11A  through  FIG. 11C . The thread engaging member  33  may be comprised of any suitable rigid or semi-rigid material, such as metal (such as steel, steel alloys, aluminum, copper, brass, or other metals or metal alloys), polymers (such as PVC, polyethylene, polypropylene, ABS, NYLON and NYLON/glass combinations, and other polymers), wood, fiberglass, carbon-based or other composites, or other materials or a combination of such materials. Although the thread engaging flange member  33   a  and the thread engaging tab members  33   b  are preferably comprised of the same material, they may be comprised of different materials in various embodiments. The thread engaging member  33  may be fabricated using any suitable means, such as injection molding for a thread engaging member  33  comprised of polymers and metal injection molding for a thread engaging member  33  comprised of metal. Preferably, the thread engaging member  33  is fabricated as a single piece from one material. Alternatively, the thread engaging tab members  33   b  may be separately fabricated and attached to the thread engaging flange portion  33   a  using any suitable means, such as adhesive, adhesive tape, glue or epoxy, welding, fusing, clasps, clamps, or other suitable attachment means or a combination of such means. More preferably, the thread engaging member  33  has the geometry illustrated in  FIG. 11A  through  FIG. 11C , and is comprised of a NYLON/glass combination, which may be fabricated using injection molding. It is to be noted that there may be more than one thread engaging member  33  utilized in some embodiments of the present invention. 
     Adjusting member internal connecting means are used to operatively connect the components (duct seal member  31 , bracing member  32 , and thread engaging member  33  in the device  15 ) comprising the adjusting connecting member  30  together. In the embodiment of the device  15  illustrated in  FIG. 1  and  FIG. 11A  through  FIG. 11C , the components (duct seal member  31 , bracing member  32 , and thread engaging member  33 ) comprising the adjusting connecting member  30  may initially be in an unassembled form. The user of the device  15  may position the thread engaging member  33  adjacent to the exterior surface  31   e  of the duct seal member  31 , so that the thread engaging flange member  33   a  is also adjacent to the inlet seal flange portion  31   a . A portion of each of the thread engaging members  33   b  also extends through the openings  31   f  in the duct seal member  31 , so that at least a portion of the thread engaging means (thread engaging tab members  33   b  in this embodiment) is adapted to be positioned between the duct (pipe  70 ) and the duct seal member  31 . Preferably, there is a relatively tight fit between the thread engaging tab members  33   b  and the openings  31   f , so that there is a fluid-tight seal between them. The user may then position the duct seal member  31  and the thread engaging member  33  within the bracing member  32  by slightly deforming the outlet seal flange portion  31   c  and then inserting that end of the duct seal member  31  into the bracing member  32 . The user may then slide the duct seal member  31  along the interior surface of the bracing member  32  until the thread engaging flange member  33   a  is adjacent to the inlet open end  32   a  of the bracing member  32 , and the outlet seal flange portion  31   c  of the duct seal member  31  is adjacent to the outlet open end  32   b  of the bracing member  32 . Preferably, the size and shape of the duct seal member  31 , the thread engaging member  33 , and the bracing member  32  is such that the inlet seal flange portion  31   a  of the duct seal member  31  and the thread engaging member  33   a  fit tightly against one another and the inlet open end  32   a  of the bracing member  32 , so that an approximately fluid-tight seal is formed between them within the anticipated operating pressure of the device  15 . In addition, the size and shape of the duct seal member  31 , the thread engaging member  33 , and the bracing member  32  is preferably such that the outlet seal flange portion  31   c  of the duct seal member  31  fits tightly against the outlet open end  32   b  of the bracing member  32 , so that an approximately fluid-tight seal is formed between them within the anticipated operating pressure of the device  15 . In these embodiments, the adjusting member internal connecting means are comprised of the force and friction that holds the components (duct seal member  31 , bracing member  32 , and thread engaging member  33 ) comprising the adjusting connecting member  30  in place relative to one another. 
     As illustrated in  FIG. 1 , the user may then connect the assembled adjusting connector member  30  to the casing member  20  using the casing connecting means, which are described in more detail below. The user may then insert the duct (pipe  70 ) into the device  15  illustrated in  FIG. 1  and  FIG. 11A  through  FIG. 11C . As the duct (pipe  70 ) is inserted, it impinges upon the interior surface  31   d  of the duct seal member  31 . In addition, if the duct (pipe  70 ) has threads  70   a  on its exterior surface at the end thereof, the threads  70   a  may impinge (or engage) upon the portions of the thread engaging tab members  33   b  that extend through the openings  31   f  in the duct seal member  31 . In order to maximize thread  70   a /thread engaging tab member  33   b  engagement, the user may twist or rotate the duct (pipe  70 ) in a manner that causes the threads  70   a  to interlock with the thread engaging tab members  33   b . It may not, however, be necessary to rotate the duct (pipe  70 ) in all embodiments of the present invention. As the duct (pipe  70 ) is rotated, the thread engaging tab members  33   b  may draw the duct (pipe  70 ) down into the duct seal member  31 . As the duct (pipe  70 ) is drawn into the duct seal member  31 , the duct seal member  31  changes shape (which may also typically involve expanding) to conform to the exterior surface of the duct (pipe  70 ). Preferably, the duct (pipe  70 ) is drawn into the duct seal member  31  a distance that is beyond the openings  31   f  so that a fluid-tight seal is formed between the duct seal member  31  and the duct (pipe  70 ) around the perimeter of the duct (pipe  70 ) exterior surface. In some embodiments, the portions of the thread engaging tab members  33   b  that extend through the openings  31   f  in the duct seal member  31  may retract into the openings  31   f  as the duct seal member  31  conforms to fit the duct (pipe  70 ) as the duct (pipe  70 ) is being inserted. In these embodiments, this retraction allows the interior surface  31   d  of the duct seal member  31  to be positioned adjacent to the exterior surface of the duct (pipe  70 ), while still preferably maintaining a fluid-tight seal between the openings  31   f  and the thread engagement tab members  33   b . As fluid is transferred from the duct (pipe  70 ) through the device  15  in operation of the device  15 , there are no leaks that allow fluid to escape from the device  15  or the interfaces between the duct (pipe  70 ) and the device  15 . When the user is finished using the device  15 , the adjusting connector member  30  may be removed from the casing member  20 . The adjusting connector member  30  may then be disassembled for cleaning and reassembled for future reuse. 
     Although the embodiment of the adjusting connector member  30  described immediately above is the preferred embodiment, the adjusting member internal connecting means may take other forms in other embodiments. For example, rather than the compressive force and friction between the components (duct seal member  31 , bracing member  32 , and thread engaging member  33 ) holding them together relative to one another, one or more of the components may be connected to any combination of other components by removable means, such as friction, clasps, clamps, clips, pins, hinges, other connectors or other types of connectors, either alone or in conjunction with one another in different combinations. In addition, the adjusting member internal connecting means may connect one or more of the components (duct seal member  31 , bracing member  32 , and thread engaging member  33 ) together, or to any combination of other components by permanent means, such as adhesives, epoxies, welding, fusing, nails, screws, nuts, bolts, or other fasteners or a combination of such means. Alternatively, in some embodiments, the components (duct seal member  31 , bracing member  32 , and thread engaging member  33 ) may be fabricated as a single component, either alone or as a part of the casing member  20 . It is to be noted, however, that the case cap connecting means may or may not be utilized to facilitate a fluid-tight seal between the adjusting connector member  30  and the case body  21 . In some embodiments, a fluid-tight seal may be inherent in the type of adjusting member internal connecting means used (such as welding or fusing), or it may be created in whole or in part by the casing connecting means (as described in more detail below). The preferred characteristics of the adjusting member internal connecting means are dependent upon a number of different factors, such as the anticipated range of shapes and sizes of the duct (pipe  70 ), the size, shape, material composition and configuration of the adjusting connector member  30 , the type of casing connecting means (which are described in more detail below), the anticipated operating pressures of the device  15 , the materials comprising and the shape of the case body  21 , the preferences of the user of the device  15 , and other factors. 
     It is to be noted that the adjusting connector member  40  illustrated in  FIG. 12A  through  FIG. 12C  may have substantially the same structure, characteristics, features, functions and operation as any of the embodiments of the adjusting connecting member  30  illustrated in  FIG. 11A  through  FIG. 11C , except that adjusting connector member  40  is adapted to receive ducts (such as pipe  70 ) that are generally smaller than for use with the adjusting connector member  30 . In the illustrated embodiment, the shape and exterior dimensions of the adjusting connector member  40  are substantially the same as those for adjusting connector member  30 , so that they are interchangeable in use with the casing member  20 , as described in more detail below. Thus, in the illustrated embodiment, the adjusting connector member  40  is generally comprised of a duct seal member  41 , a bracing member  42 , a thread engaging member  43 , and adjusting member internal connecting means for operatively connecting such components together, which means may comprise any of the embodiments of the adjusting member internal connecting means described above and illustrated in connection with  FIG. 11A  through  FIG. 11C . The duct seal member  41  is further comprised of an inlet seal flange portion  41   a , a seal sheath portion  41   b  that extends from the seal flange portion  41   a , and an outlet seal flange portion  41   c  that is positioned at the distal end of the seal sheath portion  41   b . The duct seal member  41  is further comprised of a seal interior surface  41   d  and a seal exterior surface  42   e . The seal sheath portion  41   b  also has a plurality of openings  41   f  positioned therein, which cooperate with the thread engaging member  43  in the same manner as the thread engaging member  33  cooperates with the openings  31   f  of the duct seal member  31 , as described above and illustrated in connection with  FIG. 11A  through  FIG. 11C . In the illustrated embodiment, the duct seal member  41  is also generally shaped as an hourglass (so that at least a portion is also shaped approximately as a hyperboloid), and the bracing member  42  has a brace inlet open end  42   a  and a brace outlet open end  42   b . Also in the illustrated embodiment, the bracing member  42  is a tubular-shaped shell member. In the illustrated embodiment, the thread engaging member  43  is comprised of a thread engaging flange member  43   a  and at least one thread engaging tab member  43   b  that extends from the interior perimeter of the thread engaging flange member  43   a  into the vicinity of the exterior surface  41   e  of the duct seal member  41 . Portions of the thread engaging tab members  43   b  extend through openings  41   f  in the duct seal member  41 . Thus, as the duct (such as pipe  70 ) is inserted into the device  15  (and the adjusting connector member  40 ), any threads on the duct engage the portions of the thread engaging tab members  43   b  that extend through the openings  41   f  of the duct seal member  41  in the same manner as for the thread engaging member  33 , as described above and illustrated in connection with  FIG. 11A  through  FIG. 11C   
     In other embodiments, the adjusting connector members  30 ,  40  may have different shapes, sizes, features and characteristics. For example, as illustrated in  FIG. 13 , the adjusting connector member  60  is comprised of a duct seal member  61  (as duct sealing means), a bracing member  62  (as bracing means), and adjusting member internal connecting means for connecting such components together, which means may comprise any of the adjusting member internal connecting means described above and illustrated in connection with  FIG. 11A  through  FIG. 11C . In this embodiment, the duct seal member  61  is further comprised of an inlet seal flange portion  61   a  and a seal sheath portion  61   b  that extends from the seal flange portion  61   a . The seal sheath portion  61   b  has a plurality of openings  61   f  positioned therein, which cooperate with the bracing member  62  in the manner described in more detail below. In this embodiment, the duct seal member  61  is generally shaped as a hyperboloid, but not as an hourglass, illustrating (among other things) how the duct sealing means may have a different shape and configuration in various embodiments of the present invention. Also in this embodiment, the bracing member  62  is semi-transparent and is comprised of a bracing flange member  62   a , a bracing shell portion  62   c  that extends from the bracing flange portion  62   a , at least one duct stop member  62   d , and thread engaging means (thread engaging tab members  62   a ′ in this embodiment), which allow a portion of the duct sealing means (duct seal member  61 ) to change shape to conform to the shape of the exterior surface at the end of the duct (not illustrated), while also engaging any threads on the exterior surface of the duct, which also may assist in holding the duct, the duct sealing means (duct seal member  61 ), and the bracing means (bracing member  62 ) in place relative to one another and the casing member (not illustrated), all in a manner similar to that described for the thread engaging means described in more detail above and illustrated in connection with  FIG. 11A  through  FIG. 11C . In the illustrated embodiment, the thread engaging means are comprised of at least one thread engaging tab member  62   a ′ that extends from the interior perimeter of the bracing flange member  62   a  into the vicinity of the exterior surface of the duct seal member  61 . In other embodiments, the at least one thread engaging tab member  62   a ′ may extend from another portion of the bracing member  62  and the bracing member  62  may not have a bracing flange portion  62   a . Portions of the thread engaging tab members  62   a ′ extend through openings  61   c  in the duct seal member  61 , and the thread engaging tab members  62   a ′ operatively cooperate with the duct seal member  61  in substantially the same manner as the thread engaging tab members  33   b  cooperate with the duct seal member  31 , as described in more detail above and illustrated in connection with  FIG. 11A  through  FIG. 11C . Thus, as the duct is inserted into the adjusting connector member  60 , any threads on the duct may engage the portions of the thread engaging tab members  62   a ′ that extend through the openings  61   c  of the duct seal member  61  in substantially the same manner as the thread engaging tab members  33   b  engage the threads  70   a  of the duct (pipe  70 ), as described in more detail above and illustrated in connection with  FIG. 11A  through  FIG. 11C . The embodiment of the adjusting connector member  60  illustrated in  FIG. 13  illustrates, among other things, how the bracing means and the thread engaging means may be combined into a common structural element (bracing member  62  in this embodiment). It is to be noted that there are other combination structures that may also be utilized, all of which are included within the spirit and scope of the invention as defined by the appended claims. The at least one duct stop member  62   d  is adapted to stop the travel of the duct into the adjusting connector member  60  at a predetermined position. The at least one duct stop member  62   d  may have a different size, shape or configuration in other embodiments. For example, the at least one duct stop member  62   d  may not extend across the entire width of the interior space of the bracing member  62 . In addition, other embodiments of the bracing means (such as bracing members  32 ,  42 ,  162 ,  262 ,  362 ,  462  illustrated in  FIG. 11A  through  FIG. 17A ) may also incorporate one or more duct stop members (such as duct stop member  62   d ) as a part thereof. In other embodiments, the casing member (such as casing members  20 ,  320 ,  420 ,  720 ,  820 ,  820 ,  920 ,  1020  described in more detail above and illustrated in connection with  FIG. 1  through  FIG. 10  and  FIG. 18  through  FIG. 20 ) may also incorporate one or more duct stop members (such as duct stop member  62   d ) as a part thereof. 
     Yet another embodiment of an adjusting connector member  160  is illustrated in  FIG. 14 . In this embodiment, the adjusting connector member  160  is comprised of a duct seal member  161  (as duct sealing means), a bracing member  162  (as bracing means), a thread engaging member  163  (as thread engaging means), and adjusting member internal connecting means for operatively connecting such components together, which means may comprise any of the adjusting member internal connecting means described above and illustrated in connection with  FIG. 11A  through  FIG. 11C . In this embodiment, the duct seal member  161  is further comprised of an inlet seal flange portion  161   a , a seal sheath portion  161   b  that extends from the seal flange portion  161   a , and an outlet seal flange portion  161   c  positioned at the distal end of the seal sheath portion  161   b . This embodiment of the seal sheath portion  161   b  does not, however, have any openings (such as openings  61   f  illustrated in  FIG. 13 ), illustrating how the duct seal member  161  need not have such openings in all embodiments of the present invention. Also in this embodiment, the bracing member  162  is a semi-transparent, tubular-shaped shell member having a brace inlet open end  162   a  and a brace outlet open end  162   b . The duct seal member  161  and the bracing member  162  operatively cooperate in substantially the same manner as the duct seal member  61  and the bracing member  62 , as described in more detail above and illustrated in connection with  FIG. 11A  through  FIG. 11C , except that the thread engaging member  163  is not positioned between the inlet seal flange portion  161   a  and the brace inlet open end  162   a . In this embodiment, the thread engaging member  163  is comprised of a thread engaging flange member  163   a  and thread engaging tab members  163   b  that extend from the interior perimeter of the thread engaging flange member  163   a  into the vicinity of the interior surface  161   d  of the duct seal member  161 , so that at least a portion of the thread engaging means (thread engaging tab members  163   b  in this embodiment) is adapted to be positioned between the duct (not illustrated) and the duct seal member  161 . The thread engaging flange member  163   a  is positioned approximately adjacent to the inlet seal flange portion  161   a . By “approximately adjacent,” it is meant that the thread engaging flange member  163   a  is generally intended to be positioned adjacent to inlet seal flange portion  161   a , but that in some embodiments the thread engaging flange member  163   a  may be positioned adjacent to another portion (such as the interior surface of the seal sheath portion  161   b ) of the duct seal member  161 , or there may be other members placed between the thread engaging flange member  163   a  and the inlet seal flange portion  161   a.    
     This embodiment illustrates how the thread engaging means (thread engaging member  163 ) may be positioned on the surface (interior surface  161   d ) of the duct seal member  161  opposite of the bracing means (bracing member  162 ). The thread engaging tab members  163   b  are adapted to engage any threads on a duct (not illustrated) that may be inserted into the adjusting connector member  160 . Thus, if the duct has threads on its exterior surface at the end thereof, the threads may impinge (or engage) upon the thread engaging tab members  163   b . The user may twist or rotate the duct in a manner that causes the threads to interlock with the thread engaging tab members  163   b , so that the thread engaging tab members  163   b  draw the duct down into the duct seal member  161  as the duct is rotated. As the duct is drawn into the duct seal member  161 , it changes shape (which may also typically involve expanding) to conform to the exterior surface of the duct, preferably forming a fluid-tight seal between the duct seal member  161  and the duct around the perimeter of the duct exterior surface. In cases involving relatively small duct sizes, the duct may impinge upon the interior surface  161   d  of the duct seal member  161  without engaging the thread engaging tab members  163   b . In such cases, friction alone may be used to hold the duct in place relative to the duct seal member  161 . 
     Yet another embodiment of an adjusting connector member  260  is illustrated in  FIG. 15A  and  FIG. 15B . In this embodiment, the adjusting connector member  260  is comprised of a duct seal member  261  (as duct sealing means), a bracing member  262  (as bracing means), at least one compressible insert  265  (as a portion of the bracing means), and adjusting member internal connecting means for connecting such components together, which means may comprise any of the adjusting member internal connecting means described above and illustrated in connection with  FIG. 11A  through  FIG. 11C . In this embodiment, the duct seal member  261  is further comprised of an inlet seal flange portion  261   a , a seal sheath portion  261   b  that extends from the seal flange portion  261   a , and an outlet seal flange portion  261   c  positioned at the distal end of the seal sheath portion  261   b . This embodiment of the seal sheath portion  261   b  does not, however, have any openings (such as openings  61   f  illustrated in  FIG. 13 ). Also in this embodiment, the bracing member  262  is a semi-transparent, tubular-shaped shell member having a brace inlet open end  262   a  and a brace outlet open end  262   b . The duct seal member  261  and the bracing member  262  operatively cooperate in substantially the same manner as the duct seal member  61  and the bracing member  62 , as described in more detail above and illustrated in connection with  FIG. 11A  through  FIG. 11C , except that there is not a thread engaging member positioned between the inlet seal flange portion  261   a  and the bracing inlet open end  262   a . In this embodiment, the bracing means are further comprised of one or more compressible inserts  265  positioned in the space between the duct seal member  261  and the bracing member  262 . As the duct (not illustrated) is inserted into the adjusting connector member  260 , the duct seal member  261  generally changes shape (typically expanding radially outward), exerting pressure against the compressible insert  265 . As the compressible insert  265  is compressed, it creates a counter force that exerts pressure radially inward against the duct seal member  261 , which is forced against the exterior surface of the duct, tending to hold the duct in place relative to the duct seal member  261 . In various embodiments, the compressible insert  265  may have almost any shape or combination of shapes, as long as the shape of the compressible insert  265  allows it to perform an intended function of exerting radial inward pressure against the duct seal member  261 . As is illustrated in  FIG. 15A  and  FIG. 15B , one compressible insert  265  may extend circumferentially around the entire adjacent exterior surface (not illustrated because it is covered by the compressible insert  265 ) of the duct seal member  261 . Alternatively, one or more compressible inserts  265  may be placed adjacent to only a portion of such exterior surface of the duct seal member  261 . In the illustrated embodiment, the compressible insert  265  is used without thread engaging means (such as the thread engaging tab members  62   a ′,  163   b  illustrated in  FIG. 13  and  FIG. 14 , respectively). In other embodiments, the adjusting connector member  260  may further comprise thread engaging means (such as the thread engaging member  163  illustrated in  FIG. 14 ), so that such thread engaging means may operate in conjunction with a compressible insert  265 . 
     In some embodiments, as illustrated in  FIG. 15A  and  FIG. 15B , the at least one compressible insert  265  may be comprised of a resilient porous or open-cell foam material (such as polyurethane foam or another type of open cell foam material or a combination of such foam materials) that is compatible with the fluid to be carried by the duct (not illustrated). In addition, the compressible insert  265  may have voids, channels or other passages or a combination of the same positioned within the foam that collapse when the duct is inserted into the adjusting connector member  260 . In some embodiments, the foam comprising the compressible insert  265  may be covered with a thin layer or covering of flexible material, such as rubber or another flexible polymer, to isolate the compressible insert  265  from the fluid carried by the duct. In other embodiments, the at least one compressible insert  265  may be comprised of one or more hollow, inflatable bladders that contain a compressible fluid, such as air or nitrogen. In this case, the bladders may be constructed in whole or in part of rubber, synthetic rubber, another flexible polymer, cloth, fabric, or other flexible materials or a combination of such materials. In yet other embodiments, the compressible inserts  265  may be comprised of semi-flexible materials that have a structure allowing them to be compressed, while exerting a counter force against compression. For example, the compressible inserts  265  may be comprised of a semi-flexible polymer, such as silicone, having a “honeycomb” pattern of voids or channels therein. It is to be noted that many different combinations of materials and structures may be utilized in conjunction with the at least one compressible insert  265 , all of which are included within the spirit and scope the present invention as defined by the appended claims. The compressible insert  265  may be fabricated using any suitable means, which are well known in the relevant art. The various components comprising the adjusting connector member  260  may be assembled by deforming the outlet seal flange portion  261   c  of the duct seal member  261 , inserting the deformed end of the duct seal member  261  into and through the interior open space of the compressible insert  265 , and then also deforming the end of the compressible insert  265  adjacent to the outlet seal flange portion  261   c  and inserting the deformed end into and through the inlet open end  262   a  of the bracing member  262 . 
     Yet another embodiment of a duct seal member  361  is illustrated in  FIG. 16 . In this embodiment, the duct seal member  361  is comprised of an inlet seal flange portion  361   a , a seal sheath portion  361   b  that extends from the inlet seal flange portion  361   a , and an outlet seal flange portion  361   c  positioned at the distal end of the seal sheath portion  361   b . This embodiment of the seal sheath portion  361   b  does not, however, have any openings (such as openings  61   f  illustrated in  FIG. 13 ). Instead, the duct seal member  361  further comprises thread engaging means (thread engaging tab members  361   e  in this embodiment), illustrating how the duct seal member  361  may incorporate such means in some embodiments of the present invention. In this embodiment, the thread engaging means are comprised of at least one thread engaging tab member  361   e  that extends from the interior surface of the duct seal member  361 , so that at least a portion of the thread engaging means (at least one thread engaging tab member  361   e  in this embodiment) is positioned between the duct (not illustrated) and the duct seal member  361 . In the illustrated embodiment, the thread engaging tab members  361   e  are adapted to engage any threads on a duct (not illustrated) that may be inserted into the duct seal member  361 . Thus, if the duct has threads on its exterior surface at the end thereof, the threads may impinge (or initially engage) upon the thread engaging tab members  361   e . The user may twist or rotate the duct in a manner that causes the threads to interlock with the thread engaging tab members  361   e , so that the thread engaging tab members  361   e  draw the duct down into the duct seal member  361  as the duct is rotated. As the duct is drawn into the duct seal member  361 , the duct seal member  361  changes shape (which may also typically involve expanding) to conform to the exterior surface of the duct, preferably forming a fluid-tight seal between the duct seal member  361  and the duct around the perimeter of the duct exterior surface. In cases involving relatively small duct sizes, the duct may not engage the thread engaging tab members  361   e . In such cases, friction alone may be used to hold the duct in place relative to the duct seal member  361 . The duct is preferably inserted into the duct seal member  361  a distance beyond the thread engaging tab members  361   e , so that the thread engaging tab members  361   e  do not unduly interfere with the formation of a fluid-tight seal between the duct seal member  361  and the exterior surface of the duct. The thread engaging tab members  361   e  are preferably constructed from the same material as the duct seal member  361  and are fabricated as a single piece, such as by casting in a mold. Alternatively, the thread engaging tab members  361   e  may be constructed from a different material, such as a rigid or semi-rigid polymer, and may be connected to the interior surface  361   d  of the duct seal member  361  by any suitable connecting or fastening means, such an adhesive, adhesive tape, epoxy, welding, fusing, or other fastening or connecting means or a combination of such means. Further, there may be fewer or more thread engaging tab members  361   e  than as illustrated, and the thread engaging tab members  361   e  may have a different shape in other embodiments, as long as they are adapted to perform their intended function of engaging any threads present on the duct, as described in more detail above. 
     Another embodiment of adjustable connecting means (adjusting connector member  460  in this embodiment) is illustrated in  FIG. 17A  and  FIG. 17B . Generally, this adjustable connecting means may comprise any of the aspects, features, characteristics, structures, functions and operations of any of the inventions disclosed in U.S. Nonprovisional patent application Ser. No. 11/879,346 filed on Jul. 17, 2007, Ser. No. 12/012,954 filed on Feb. 6, 2008, and U.S. Provisional Patent Application No. 61/062,428 filed on Jan. 25, 2008, which also name as inventor the inventor of the present invention. The entire disclosure of each of these patent applications is incorporated herein by this reference. In this embodiment, the adjustable connecting means are comprised of an adjusting connector member  460 , which is further comprised of duct sealing means, bracing means, and adjusting member internal connecting means to connect such means operatively together, all of such means being described in more detail below. The duct sealing means are generally comprised of a hollow internal seal member  461 , a hollow external seal member  464 , and seal connecting means to operatively connect them together, as described in more detail below. In this embodiment, the internal seal member  461  is comprised of an internal seal flange portion  461   a  adjacent to an internal seal inlet  461   e  and an internal seal sheath portion  461   b  that extends from the internal seal flange portion  461   a . The internal seal sheath portion  461   b  is further comprised of an internal seal interior surface  461   c  and an internal seal exterior surface  461   d , which are bounded by the internal seal inlet  461   e  and an internal seal outlet  461   f . The internal seal sheath portion  461   b  also has an internal seal slit  461   g  that runs from the interior seal outlet  461   f  along the internal seal sheath portion  461   b  a portion of the way toward the interior seal inlet  461   e . The portions  461   b ′ of the internal seal sheath portion  461   b  adjacent to the internal seal slit  461   g  are generally tapered so that the thickness of the internal seal sheath portion  461   b  is gradually reduced to zero thickness at the internal seal slit  461   g . In this embodiment of the adjusting connector member  460 , the external seal member  464  is comprised of an external seal flange portion  464   a  adjacent to an internal seal inlet  464   e  and an external seal sheath portion  464   b  extending from the external seal flange portion  464   a . The external seal sheath portion  464   b  is further comprised of an external seal interior surface  464   c  and an external seal exterior surface  464   d , which are bounded by the external seal inlet  464   e  and an external seal outlet  464   f . The external seal sheath portion  464   b  also has an external seal slit  464   g  that runs from the external seal outlet  464   f  along the external seal sheath portion  464   b  a portion of the way toward the external seal inlet  464   e . The portions  464   b ′ of the external seal sheath portion  464   b  adjacent to the external seal slit  464   g  are generally tapered so that the thickness of the external seal sheath portion  464   b  is gradually reduced to zero thickness at the external seal slit  464   g.    
     In this embodiment, the internal seal member  461  is positioned within the external seal member  464 , so that the internal seal exterior surface  461   d  faces and may be adjacent to the external seal interior surface  464   c . The internal seal flange portion  461   a  is also positioned adjacent to the external seal flange portion  464   a  and the two are operatively connected by the seal connecting means. Preferably, the seal connecting means connect the internal seal flange portion  461   a  and the external seal flange portion  464   a , as portions of the internal seal member  461  adjacent to the internal seal inlet  461   e  and of the external seal member  464  adjacent to the external seal inlet  464   e , respectively, in a manner that forms a fluid-tight seal between them. This fluid-tight seal (and the seal connecting means generally) may be formed by compression of the internal seal flange portion  461   a  against the external seal flange portion  464   a  or by use of other suitable means, such as adhesive, adhesive tape, glue, epoxy, welding, fusing, clasps, clamps, fasteners or other suitable attachment means or a combination of such means, in each case as applied to all or a portion of the internal seal flange portion  461   a  or the external seal flange portion  464   a  or both. In addition, the internal seal slit  461   g  is preferably positioned so that it is on approximately the opposite side of the duct sealing means from the external seal slit  464   g . Further, the duct sealing means (internal seal member  461  and external seal member  464 ) are generally constructed in whole or in part of materials that permit them to expand to conform to the exterior surface of the largest size of duct (not illustrated, but which may be similar to pipe  70 ) that may be connected to the adjusting connector member  460 , while still maintaining the structural integrity of the internal seal member  461  and the external seal member  464  during operation of the adjusting connector member  460 . In addition, the materials are preferably compatible with the type of fluid anticipated in the interior space of the duct. For example, the internal seal member  461  and the external seal member  464  may each be comprised of any suitable elastic material, such as rubber, synthetic rubber (including NEOPRENE), elastomers or other elastic polymers, or combinations of such materials, along with a combination that may including cloth, fabric or other flexible or semi-flexible materials. It is to be noted, however, that the internal seal member  464  and the external seal member  464  need not be constructed entirely of flexible or elastic materials. For example, the internal seal flange portion  461   a  and the external seal flange portion  464   a , or a portion of the internal seal sheath portion  461   b  and the external seal sheath portion  464   b  adjacent to the internal seal flange portion  461   a  and the external seal flange portion  464   a , respectively, or any combination thereof, may be comprised of a rigid or semi-rigid material, such as wood, ceramic, metal, fiberglass, carbon-based or other composites, rigid or semi-rigid polymers (such as polyvinyl chloride and polycarbonate), or other rigid or semi-rigid materials or a combination of such materials. This may assist in facilitating a fluid-tight seal between the internal seal flange portion  461   a , the external seal flange portion  464   a , the bracing member  462 , and the case body (not illustrated) in some embodiments. 
     Thus, as the duct is inserted into the internal seal member  461  and the external seal member  464 , the internal sheath member  461   b  and the external sheath member  464   b  change shape to conform to the shape of the exterior surface of the duct at the end thereof so that they are adapted to fit tightly against the exterior surface of the duct. In order to accommodate a larger size of duct, the internal seal sheath portion  461   b  and the external seal sheath portion  464   b  may also expand radially in a manner that causes the internal seal exterior surface  461   d  to slide circumferentially along the external seal interior surface  464   c . As this expansion occurs, the internal seal slit  461   g  and the external seal slit  464   g  may also increase in size. Because the internal seal slit  461   g  and the external seal slit  464   g  are on approximately opposite sides, the seal slits  461   g ,  464   g  do not overlap as they widen, so that portions of the internal seal sheath portion  461   b  and the external seal sheath portion  464   b  are positioned adjacent to the duct around the duct&#39;s entire circumference. This preferably forms a fluid-tight seal between the exterior surface of the duct and portions of the internal seal member  461  and the external seal member  464 . It is to be noted that the duct sealing means of this embodiment (internal seal member  461  or external seal member  464  or both) may have a different configuration in other embodiments. For example, the internal seal member  461  may not have a slit. Similarly, the external seal member  464  may not have a slit. Alternatively, both the internal seal member  461  and the external seal member  464  may not have a slit. In other embodiments, either or both slits  461   g ,  464   g  may have a different shape. For example, either or both of the slits  461   g ,  464   g  may be longer or shorter or may have a curved shape. As yet another example, the portion of the internal seal sheath portion  461   b  or the external seal sheath portion  464   b  or both adjacent to the slits  461   g ,  464   g , respectively, may not be tapered. As still another example, the placement of the slits  461   g ,  464   g  relative to one another may be different (i.e., they may not be placed on opposite sides). Further, there may be more than one slit  461   g ,  464   g  in either or both of the internal seal member  461  and the external seal member  464 , respectively. Further still, although it is preferable that the internal seal sheath portion  461   b  and the external seal sheath portion  464   b  are not attached to one another so that they can move relative to one another, in some embodiments they may be attached at one or more portions thereof. In yet other embodiments, the internal seal sheath portion  461   b  and the external seal sheath portion  464   b  may not be positioned adjacent to one another over their entire facing surfaces  461   d ,  464   c . In yet other embodiments, the internal seal member  461  and the external seal member  464  may be fabricated together as a single component. The internal seal member  461  and the external seal member  464  may be constructed using any suitable means. For example, internal seal members  461  and external seal members  464  constructed entirely of synthetic rubber may be cast in a mold. As another example, an internal seal member  461  and an external seal member  464  comprised of one or more materials may have various components assembled utilizing adhesives, welding, fusing or any other suitable means. Further, the seal connecting means are utilized in connecting the internal seal member  461  and the external seal member  464 , as described in more detail above. 
     In the embodiment of the adjusting connector member  460  illustrated in  FIG. 17A  and  FIG. 17B , the adjusting connector member  460  is further comprised of a bracing member  462  (as bracing means), and adjusting member internal connecting means for operatively connecting the duct sealing means (internal seal member  461  and external seal member  464 ) to the bracing member  462 . In this embodiment, the adjusting member internal connecting means may be comprised of any embodiment of the adjusting member internal connecting means described above and illustrated in connection with  FIG. 11A  through  FIG. 11C . Also in this embodiment, the bracing member  462  is a semi-transparent, tubular-shaped shell member having a brace inlet open end  462   a  and a brace outlet open end  462   b . The bracing member  462  may generally have any of the structures, features, characteristics, functions and operation as any of the bracing members  32 ,  42 ,  62  described in more detail above and illustrated in connection with  FIG. 11A  through  FIG. 13 . The duct sealing means  461 ,  464  and the bracing member  462  operatively cooperate in substantially the same manner as the duct seal member  61  and the bracing member  62 , as described in more detail above and illustrated in connection with  FIG. 11A  through  FIG. 11C , except that thread engaging means are not positioned between the external seal flange portion  464   a  and the brace inlet open end  462   a . In addition, the adjusting connector member  460  may also utilize at least one compressible insert (not illustrated), similar to the at least one compressible insert  265  described in more detail above and illustrated in connection with  FIG. 15A  and  FIG. 15B . Preferably, for adjusting connector members  460  utilizing internal seal members  461  and external seal members  464  of the illustrated embodiment and designed for use with tubular ducts having a nominal diameter in the range of ½″ to ¾″ carrying potable water for domestic use, the internal seal member  461  and external seal member  464  have the configuration illustrated in  FIG. 17A  and  FIG. 17B  and are constructed entirely of NEOPRENE having a thickness in the range of 1/16 inch to ⅛ inch. 
     It is to be noted that in some embodiments, as illustrated in  FIG. 18 , the adjusting connector members  830 ,  840  may comprise various combinations of components. For example, adjusting connector member  830  is comprised of a duct seal member  831 , a compressible insert  835 , and a thread engaging member  833 . Each of these components  831 ,  835 ,  833  may comprise any of the structures, features, characteristics, functions, and operation as the corresponding components  161 ,  261 ,  265 ,  263 , respectively, described in more detail above and illustrated in connection with  FIG. 14  through  FIG. 15B . In this embodiment, however, the adjusting connector member  830  does not include any bracing means. Instead, the casing member  820  (and the case body  821  in particular) serves to perform the function of a bracing member. In other embodiments, the adjusting connector member  830  may comprise the duct seal member  831  alone. In still other embodiments, the adjusting connector member  830  may comprise the duct seal member  831  in combination with either the compressible insert  835  or the thread engaging member  833 , but not both. As another example, the adjusting connector member  840  is comprised of a duct seal member  841 , a thread engaging member  843 , and a washer  845 . The duct seal member  841  and the thread engaging member  843  may comprise any of the structures, features, characteristics, functions, and operation as the corresponding components  61 ,  33 , respectively, described in more detail above and illustrated in connection with  FIG. 11A  through  FIG. 11C  and  FIG. 13 . The washer  845  may be used to assist in forming a fluid-tight seal between the thread engaging member  843  and the case body  821  in some embodiments. Once again, the adjusting connector member  840  does not include any bracing means. Instead, the casing member  820  (and the case body  821  in particular) serves to perform the function of a bracing member. In other embodiments, the adjusting connector member  840  may comprise the duct seal member  841  alone, but without any openings  84   c . Alternatively, the adjusting connector member  840  may comprise the duct seal member  841  in combination with only the thread engaging member  843 . The adjusting connector members  830 ,  840  are held in place within the open ends  821   c ,  821   g  of the case body  821  by the case cap connecting means, which comprise the threaded connections  821   d ,  822   b ,  821   h ,  823   b  in this embodiment. Although the embodiment of the device  15  illustrated in  FIG. 1  and  FIG. 11A  through  FIG. 12C  is the preferred embodiment, it is to be noted that there are numerous potential variations in the structure, features, characteristics and operation of the present invention. In each of these various embodiments, the adjusting member internal connecting means, as described above and illustrated in more detail in connection with  FIG. 1  through  FIG. 17B , may be used to operatively connect one or more of the components comprising the adjusting connector member  830 ,  840 . 
     Referring again to the embodiment of the device  15  illustrated in  FIG. 1  and  FIG. 11A  through  FIG. 12C , each of the adjusting connector members  30 ,  40  is positioned approximately within an open end  21   c ,  21   g  of the case body  21  and operatively connected to the casing member  20  by casing connecting means, which are described in more detail below. By “approximately within,” it is meant that at least one component comprising the adjusting connector members  30 ,  40 , such as the thread engaging flange member  33   a  or the inlet seal flange portion  41   a , respectively, are generally intended to be positioned adjacent to the case body open ends  21   c ,  21   g , respectively, but that other items, such as washers, o-rings or other members, may be positioned between such at least one component and the case body open ends  21   c ,  21   g , respectively, in some embodiments. For example, in the case of adjusting connector member  30 , it may be desirable in some cases to position a washer (not illustrated, but similar to the washer  845  illustrated in  FIG. 18 ) between the thread engaging flange member  33   a  and the case body open ends  2   c . This may be desirable because the thread engaging flange member  33   a  and the case body  21  may both be comprised of rigid materials that require a more flexible material between them (such as the washer) in order to form a fluid-tight seal between them. In contrast, as is the case with adjusting connector member  40 , the duct seal member  41  (which may be comprised of a flexible or elastic material) may alone provide for the formation of a fluid-tight seal between the other components of the adjusting connector member  30  (or the case cap  23  in some embodiments) and the case body  21 . In the illustrated embodiment, as the case cap  22  is screwed down onto the case body  21 , the case body open end  21   c  and the portion of the case cap  22  adjacent to the connector opening  22   a  are pressed against the inlet seal flange portion  31   a  of the duct seal member  31  and the thread engaging flange member  33   a  of the thread engaging member  33 . This compression, acting as casing connecting means to operatively connect the adjusting connector member  30  to the casing member  20 , may also provide a fluid-tight seal between the adjusting connector member  30  and the casing member  20 . In addition, the inlet seal flange portion  41   a  of the duct seal member  41  is compressed between the case body open end  21   g  and the portion of the case cap  23  adjacent to the connector opening  23   a  as the case cap  23  is screwed down onto the case body  21 , which may form a fluid-tight seal between the adjusting connector member  40  and the casing member  20 . Thus, a fluid-tight chamber (not illustrated) may be formed, which is bounded by the interior surfaces  31   d ,  41   d  of the duct seal members  31 ,  41 , respectively, the internal surfaces of the case body  21 , and the internal surfaces of the ducts (pipe  70 ). In other embodiments, the casing connecting means may be comprised of any other suitable means for operatively, as well as permanently or removably, connecting the adjusting connector members  30 ,  40  to the casing member  20 . For example, one or more components comprising the adjusting connector members  30 ,  40  may be connected to the case cap  22 ,  23 , respectively, or the case body  21  or both by an adhesive, adhesive tape, glue or epoxy or a combination of the same. Other possible casing connecting means may include welding, fusing, clasps, clamps, hinges, pins, dowels, screws, nuts, bolts, or other suitable attachment or fastening means or a combination of such means. 
     Generally, and continuing to refer to the device  15  illustrated in  FIG. 1  and  FIG. 11A  through  FIG. 12C  as an example, the casing connecting means may also comprise a modular aspect, which creates a modular system of interchangeable casing members  20  and adjusting connector members  30 ,  40 . For example, both the adjusting connector members  30 ,  40  of the device  15  and the casing member  20  are comprised of casing connecting means adapted for operatively connecting the adjusting connector members  30 ,  40  to the casing member  20 . In the illustrated embodiment, the casing connecting means of the adjusting connector member  30  are further comprised of the inlet seal flange portion  31   a , the thread engaging flange member  33   a , and the bracing member  32  that cooperate with the portion of the case body  21  adjacent to the case body open end  21   c  and the portion of the case cap  22  adjacent to the connector opening  22   a  to permit the adjusting connector member  30  to be connected to the casing member  20 . In this embodiment, the casing connecting means may also comprise a washer (not illustrated, but similar to the washer  845  illustrated in  FIG. 18 ) that assists in forming a fluid-tight seal between the adjusting connector member  30  and the casing member  20  so that fluids contained within the device  15  do not leak out through the seams formed between the adjusting connector member  30  and the casing member  20 . Although a fluid-tight seal is preferably formed between the adjusting connector member  30  and the case body  21 , a fluid-tight seal need not be formed in all embodiments. In the illustrated embodiment, the inlet seal flange portion  31   a  and the thread engaging flange member  33   a  are each generally shaped approximately as an annulus, while the bracing member  32  is approximately tubular in shape. The portion of the case cap  22  adjacent to the connector opening  22   a  is approximately annular in shape, while the portion of the case body  21  adjacent to the case body open end  21   c  is annularly shaped at its open end  21   c , with a cylindrical portion bounding the case body interior space  20   a  that extends away from such end  2   c . The shapes and sizes of these components (adjusting connector member  30 , case body  21 , and case cap  22 ) is such that the bracing member  32  fits within the cylindrical portion of the case body  21  adjacent to the casing interior space  20   a , while the inlet seal flange portion  31   a  and the thread engaging flange member  33   a  (including any washer) of the adjusting connector member  30  is positioned adjacent to and compressed between the annular portion of the case body  21  adjacent to the case body open end  21   c  and the annular portion of the case cap  22  adjacent to the connector opening  22   a . Thus, the adjusting connector member  30  is connected to the casing member  20  by the casing connecting means, which generally comprise the size and shape of the components (adjusting connector member  30 , case body  21 , and case cap  22 ) and the case cap connecting means operating in cooperation with one another. 
     The casing member  20  and the other adjusting connector member  40  of the embodiment of the device  15  illustrated in  FIG. 1  and  FIG. 11A  through  FIG. 12C  incorporate the same casing connecting means described above with respect to adjusting connector member  30 , so that adjusting connector member  40  is interchangeable with adjusting connector member  30  in operation of the device  15 . For example, the portion of the case body  21  adjacent to the other open end  21   g  of the case body  21  and the case cap  23  have features and characteristics that are operatively the same as those for the portion of the case body  21  adjacent to the open end  21   c  of the case body  21  and the case cap  22 , respectively, described above. In addition, the adjusting connector member  40  is also comprised of an inlet seal flange portion  41   a , a thread engaging flange portion  43   a , and a bracing member  42  that cooperate with the portion of the case body  21  adjacent to the case body open end  21   g  and the portion of the case cap  23  adjacent to the duct opening  23   a  to permit the adjusting connector member  40  to be connected to the casing member  20 . Thus, the inlet seal flange portion  41   a  and the thread engaging flange portion  43   a  are shaped approximately as an annulus, while the bracing member  42  is approximately tubular-shaped, and all of them are generally of the same cross-sectional size and shape as the inlet seal flange portion  31   a , the thread engaging flange portion  33   a , and the bracing member  32 , respectively. The portion of the case cap  23  adjacent to the connector opening  23   a  is approximately annular in shape, while the portion of the case body  21  adjacent to the case body open end  21   g  is annularly shaped at its open end  21   g , with a cylindrical portion bounding the casing interior space  20   a  that extends away from such end  21   g . The shapes and sizes of these components (adjusting connector member  40 , case body  21 , and case cap  23 ) is such that the inlet seal flange portion  41   a  and the thread engaging flange portion  43   a  fit within the cylindrical portion of the case body  21  adjacent to the casing interior space  20   a , while the inlet seal flange portion  41   a  and the thread engaging flange portion  43   a  (including any washer) of the adjusting connector member  40  are positioned adjacent to and compressed between the annular portion of the case body  21  adjacent to the case body open end  21   g  and the annular portion of the case cap  23  adjacent to the duct opening  23   a . As a result, the adjusting connector member  40  is connected to the casing member  20  by casing connecting means that are operatively equivalent to the casing connecting means used to connect adjusting connector member  30  to the casing member  20 . Consequently, adjusting connector member  40  may be connected to the casing member  20  at the open end  21   c  of the case body  21 , and adjusting connector member  30  may be connected to the casing member  20  at the other open end  21   g  of the case body  21 , in each case using the casing connecting means described above and illustrated in connection with the device  15  illustrated in  FIG. 1  and  FIG. 11A  through  FIG. 12C . 
     It is to be noted that any of the embodiments of any of the adjusting connector members  60 ,  160 ,  260 ,  360 ,  460 ,  830 ,  840  described in more detail above and illustrated in connection with  FIG. 13  through  FIG. 18  may also comprise the same casing connecting means, so that any of such adjusting connector members  60 ,  160 ,  260 ,  360 ,  460 ,  830 ,  840  may be operatively connected to the casing member  20  at the open ends  21   c ,  21   g  of the case body  21  as part of a modular system of interchangeable adjusting connector members  30 ,  40 ,  60 ,  160 ,  260 ,  360 ,  460 ,  830 ,  840  and casing members  20 ,  320 ,  420 ,  720 ,  820 ,  920 . It is also to be noted that the shape and configuration of each adjusting connector member  30 ,  40 ,  60 ,  160 ,  260 ,  360 ,  460 ,  830 ,  840  and each casing member  20 ,  320 ,  420 ,  720 ,  820 ,  920 , in each case comprising the casing connecting means, need not be exactly the same in order to provide for a modular system. For example, as illustrated in  FIG. 1  and  FIG. 18 , the adjusting connector members  30 ,  40  have one shape and configuration (which includes a bracing member  32 ,  42 ), while the adjusting connector members  830 ,  840  have a different shape and configuration (which do not include a bracing member, and have a different shape and configuration of thread engaging means  833 ,  843 ). Nevertheless, the adjusting connector members  830 ,  840  may be adapted to be interchangeable with the adjusting connector members  30 ,  40  as part of a modular system. It is also to be noted that there are many potential variations in the casing connecting means that may be utilized in the modular coupling system of the present invention. Generally, any suitable means currently known in the relevant art or developed in the relevant art in the future may be used, as long as such means are used consistently in a manner that accommodates the connection of all of the adjustable connecting means comprising the modular coupling system to all of the casing members comprising the modular coupling system. Thus, and referring to the device  15  illustrated in  FIG. 1  as an example, the adjusting connector members  30 ,  40  and the casing member  20  may have interacting portions of almost any shape or size, as long as the shape and size of such interacting portions cooperate to ensure that the adjusting connector members  30 ,  40  of the system can be operatively connected to the casing member  20 . For example, the adjusting connector members  30 ,  40  and the casing member  20  may have a hexagonal shape, as is disclosed in U.S. Provisional Patent Application No. 61/066,258, entitled MODULAR COUPLING SYSTEM filed on Feb. 19, 2008. Another example is presented in the device  1015  illustrated in  FIG. 20 , in which the adjusting connector member  1040  has a ridge portion  1042   e  positioned on the bracing member  1042 . The ridge portion  1042   e  fits into and operatively cooperates with a slot  1021   g ′ positioned in the open end  1021   g  of the case body  1021  that comprises the casing member  1020 . In this embodiment, if the adjusting member internal connecting means provide a permanent means of attachment, then the ridge portion  1042   e  and the slot  1021   g ′ tend to prevent the adjusting connector member  1040  from rotating within the case body open end  1021   g  if the duct (not illustrated) is rotated during its insertion into the device  1015 . 
     A method of operating a device  915  of the present invention to connect to ducts (pipe  970  and bottle spout  975   a ) of various sizes and shapes is illustrated by reference to  FIG. 19 . One duct (pipe  970 ) is connected to an adjusting connector member  940 , which is comprised of a duct seal member  941 , a thread engaging member (not illustrated), and a bracing member (not illustrated), but which have substantially the same structure, features, characteristics, functions, and operation as the duct seal member  41 , the thread engaging member  43 , and the bracing member  42 , respectively, described in more detail above and illustrated in connection with  FIG. 1  and  FIG. 12A  through  FIG. 12C . The other duct (bottle spout  975   a ) is inserted into an adjusting connector member  930 , which is comprised of a duct seal member  931 , a thread engaging member (not illustrated), and a bracing member (not illustrated), but which have substantially the same structure, features, characteristics, functions, and operation as the duct seal member  31 , the thread engaging member  33 , and the bracing member  32 , respectively, described in more detail above and illustrated in connection with  FIG. 1  and  FIG. 11A  through  FIG. 11C . 
     In operation, the end of the duct (pipe  970 ) is inserted into (and received by) the connector opening  923   a  of the casing member  920  and the adjusting connector member  940 . In this embodiment, the duct (pipe  970 ) has a generally cylindrical shape and an outside diameter within a predetermined range. For example, the pipe  970  in some embodiments may have an outside diameter within the range of 0.8 inches to 1.0 inches. In addition, the duct (pipe  970 ) may have a variety of different thread types (not illustrated) on the end thereof, or no threads at all, as described in more detail above. Thus, the device  915  is capable of connecting to a variety of different types and sizes of ducts (pipe  970 ). As the duct (pipe  970 ) is being inserted into (and received by) the device  915 , if the outside diameter of the duct (pipe  970 ) is the minimum acceptable diameter of the duct (pipe  970 ) the distal end of the duct (pipe  970 ) may travel down the longitudinal axis of the adjusting connector member  940  with only minimal contact against the portion of the thread engaging member extending through the duct seal member  941   b . The duct (pipe  970 ) is advanced into the device  915  until a portion of the duct seal member  941  has changed shape, and possibly expanded, to conform to and be positioned adjacent to the exterior surface of the duct (pipe  970 ). In other embodiments, all or any combination of the duct sealing means or the thread engaging means (which are described in more detail above and illustrated in connection with  FIG. 11A  through  FIG. 17B ) may be used to hold the pipe  970  operatively in place in the device  915 . In embodiments of the device  915  that comprise at least one duct stop member (not illustrated, but similar to the at least one duct stop member  62   d  described in more detail above and illustrated in connection with  FIG. 13 ), the duct (pipe  970 ) may be inserted into the device  915  until the duct (pipe  970 ) open end abuts against the at least one duct stop member. Where the duct (pipe  970 ) has threads and is large enough to engage the thread engaging member of the adjusting connector member  940 , the thread engaging member may engage the threads of the duct (pipe  970 ) in substantially the same manner as the thread engaging members  33 ,  43  engage the threads  70   a  of the duct (pipe  70 ), as described in more detail above and illustrated in connection with  FIG. 11A  through  FIG. 12C . 
     With respect to connection to the other duct (bottle spout  975   a ), the end of the duct (bottle spout  975   a ) is inserted into (and received by) the connector opening  922   a  of the casing member  920  and the adjusting connector member  930 . In this embodiment, the duct (bottle spout  975   a ) is the spout of a bottle  975  that may have a variety of different sizes and shapes. The duct (bottle spout  975   a ) has a generally cylindrical shape and an outside diameter within a predetermined range. For example, the bottle spout  975   a  in some embodiments may have an outside diameter within the range of 0.8 inches to 1.3 inches. In addition, the duct (bottle spout  975   a ) may have a variety of different thread types (not illustrated) on the end thereof, or no threads at all, as described in more detail above. Thus, the device  915  is also capable of connecting to a variety of different types and sizes of bottles or other containers having spouts  975   a  of varying sizes and shapes. As the duct (bottle spout  975   a ) is being inserted into (and received by) the device  915 , if the outside diameter of the duct (bottle spout  975   a ) is the maximum acceptable diameter of the duct (bottle spout  975   a ) the distal end of the duct (bottle spout  975 ) will impinge upon the portion of the thread engaging member of the adjusting connector member  930  extending through the duct seal member  931   b . If the duct (bottle spout  975   a ) has threads, the thread engaging member may engage the threads of the duct (bottle spout  975   a ) in substantially the same manner as the thread engaging members  33 ,  43  engage the threads  70   a  of the duct (pipe  70 ), as described in more detail above and illustrated in connection with  FIG. 11A  through  FIG. 12C . The duct (bottle spout  975   a ) also impinges upon the duct seal member  931 , and as the duct (bottle spout  975   a ) is advanced into the device  915 , a portion of the duct seal member  941  changes shape, generally expanding radially, to conform to and be positioned adjacent to the exterior surface of the duct (bottle spout  975   a ). In other embodiments, all or any combination of the duct sealing means or the thread engaging means (which are described in more detail above and illustrated in connection with  FIG. 11A  through  FIG. 17B ) may be used to hold the bottle spout  975   a  operatively in place in the device  915 . In embodiments of the device  915  that comprise at least one duct stop member (not illustrated, but similar to the at least one duct stop member  62   d  described in more detail above and illustrated in connection with  FIG. 13 ), the duct (bottle spout  975   a ) may be inserted into the device  915  until the duct (bottle spout  975   a ) open end abuts against the at least one duct stop member. Preferably, once the duct (bottle spout  975   a ) is in position in the device  915 , the duct support members  922   g  may be deformed radially inward until they are positioned adjacent to a surface of the bottle  975 , so that the duct support members  922   g  together are adapted to hold the bottle  975  in place relative to the device  915  while the duct (bottle spout  975   a ) is connected to the device  915 . In embodiments where the case body connecting section  921   i  comprises a valve mechanism, as is illustrated in  FIG. 19 , the valve mechanism may initially be closed, so that fluids do not flow through the casing member  915 . Once the ducts (pipe  70  and bottle spout  975   a ) are connected to the device  915 , the valve mechanism may be opened the desired amount to produce the desired rate of fluid flow and is then closed when the desired amount of fluid has been transferred through the device  915 . Thus, the user of the device  915  may be provided with more control over fluid flow through the device  915  than other means (such as a funnel or siphon) used to transfer fluids. 
     Continuing to refer to the embodiment of the device  915  illustrated in  FIG. 19 , in some cases, supplemental duct sealing means may be utilized to provide or enhance the seal between the duct seal member  931  and the duct (bottle spout  975   a ). This may be the case where the device  915  may be operating at relatively high pressure, or where only minimal contact may be present between the duct seal member  931  and the exterior surface of the duct (bottle spout  975   a ) because of minimum duct (bottle spout  975   a ) size, or where the thread engaging member of the adjusting connector member  930  is not adequate to hold the duct (bottle spout  975   a ) in place in the device  915 . The duct sealing means may include adhesive, glue, epoxy or other joining compound or a combination of such means that is stored in a container or other receptacle, which is then positioned as a film  990  on a portion of the duct sealing means (duct seal member  931 ) or the duct (bottle spout  975   a ) or both prior to connecting the duct (bottle spout  975   a ) to the device  915 . The adhesive film  990  may provide for a relatively permanent attachment of the duct seal member  931  to the duct (bottle spout  975   a ), which is not preferred, so that the duct seal member  931  is not easily removed from the duct (bottle spout  975   a ). An example of this type of adhesive is Cyanoacrylate(methyl-2-cyanoacrylate), which may be typically sold under the trademark SUPERGLUE. Alternatively, the adhesive film  990  may provide for non-permanent attachment of the duct seal member  931  to the duct (bottle spout  975   a ), which is preferred, so that the duct seal member  931  is relatively easily removed from the duct (bottle spout  975   a ) after use of the device  915  is completed. An example is an adhesive similar to rubber cement made from a polymer (such as latex) mixed in a solvent such as acetone, hexane, heptane or benzene to keep the polymer fluid prior to use. In addition, the adhesive film  990  may be comprised of an adhesive layer  990  with a peel-off strip (not illustrated) positioned over the adhesive layer  990 , which is removed prior to insertion of the duct (bottle spout  975   a ) into the device  915 . For example, this type of adhesive layer  990  and peel-off strip may be comprised of double coated urethane, vinyl or polyethylene adhesive tapes with release liners, such as those manufactured by the 3M Company. 
     Thus, referring to the embodiment of the device  15  illustrated in  FIG. 1  and  FIG. 11A  through  FIG. 12C  as an example, as is apparent from the foregoing description, the preferred type and structure of each of the duct seal members  31 ,  41 , the bracing members  32 ,  42 , the thread engaging members  33 ,  43 , and the adjusting member internal connecting means, as well as other members comprising the device  15 , are dependent upon numerous different factors. In addition, the preferred types and structure of the casing member  20 , the adjusting connector members  30 ,  40 , and the casing connecting means (which are described in more detail above), are also dependent upon numerous different factors. A device  15  having a particular combination of features appropriate for one type of operating condition may not be appropriate for other types of operating conditions. In addition to the preferences described above, in the case of a device  15  designed for use with room temperature domestic potable water and capable of accommodating pipes  70 ,  75  in the range of ¾″ to ½″ nominal diameter, the type of casing member  20  described above and illustrated in connection with  FIG. 1  is preferred, and the preferred casing connecting means are that which is a part of the adjusting connector member  1040  illustrated in  FIG. 20 . 
     The present invention also includes kits (not directly illustrated) that comprise various combinations of components of the present invention, such components being described in more detail elsewhere herein. For example, a kit may comprise two or more adjusting connector members  30 ,  40 ,  60 ,  160 ,  260 ,  330 ,  360 ,  430 ,  440 ,  460 ,  730 ,  830 ,  840 ,  930 ,  940 ,  1040 , as described in more detail above and illustrated in connection with  FIG. 1 ,  FIG. 5 ,  FIG. 6 , and  FIG. 10  through  FIG. 20 , comprising any combination or combinations of any embodiments of such adjusting connector members. In addition, a kit may comprise two or more of the duct sealing means, bracing means, or thread engaging means, as such means are described in more detail above and illustrated in connection with  FIG. 1 ,  FIG. 5 ,  FIG. 6 , and  FIG. 10  through  FIG. 20 , or any combination or combinations of any embodiments of such duct sealing means, bracing means, or thread engaging means. Further, a kit may comprise one or more adjusting connector members  30 ,  40 ,  60 ,  160 ,  260 ,  330 ,  360 ,  430 ,  440 ,  460 ,  730 ,  830 ,  840 ,  930 ,  940 ,  1040  along with any combination or combinations of any embodiments of one or more of the duct sealing means, bracing means, or thread engaging means, as all are described in more detail above and illustrated in connection with  FIG. 1 ,  FIG. 5 ,  FIG. 6 , and  FIG. 10  through  FIG. 20 , or any combination or combinations of any embodiments of any of the above.

A kit may also include one or more of the case caps  22 ,  23 ,  322 ,  323 ,  422 ,  423 ,  522 ,  622 ,  722 ,  822 ,  823 ,  922 ,  923 , one or more of the case body conduit sections  21 ′,  21 ″,  121 ′,  121 ″,  221 ′,  221 ″,  321 ′,  321 ″,  421 ′,  421 ″,  721 ′,  721 ″,  821 ′,  821 ″,  921 ′,  921 ″,  1021 ″, or one or more of the case body connecting sections  21   i ,  121   i ,  221   i ,  321   i ,  921   i , as all are described in more detail above and illustrated in connection with  FIG. 1  through  FIG. 10  and  FIG. 18  through  FIG. 20 , in any combination or combinations of any embodiments of any of the above with one another. In addition, a kit may comprise one or more casing members  20 ,  320 ,  420 ,  720 ,  820 ,  820 ,  920 ,  1020 , as described in more detail above and illustrated in connection with  FIG. 1  through  FIG. 10  and  FIG. 18  through  FIG. 20 , in any combination or combinations with any embodiment of one or more of the case caps  22 ,  23 ,  322 ,  323 ,  422 ,  423 ,  522 ,  622 ,  722 ,  822 ,  823 ,  922 ,  923 , one or more of the case body conduit sections  21 ′,  21 ″,  121 ′,  121 ″,  221 ′,  221 ″,  321 ′,  321 ″,  421 ′,  421 ″,  721 ′,  721 ″,  821 ′,  821 ″,  921 ′,  921 ″,  1021 ″, or one or more of the case body connecting sections  21   i ,  121   i ,  221   i ,  321   i ,  921   i , as all are described in more detail above and illustrated in connection with  FIG. 1  through  FIG. 10  and  FIG. 18  through  FIG. 20 .
