Title: Down well pipe cutting device

Description:
BACKGROUND 
     Technical Field 
     The present invention relates to ultra-high pressure (UHP) cutting devices, and specifically to UHP cutting devices for sublevel use for cutting pipe casings and liners for example in the dismantling of existing oil, gas and/or utility well bores or lines. 
     Background Information 
     The abandonment of non-producing or uneconomic oil or gas wells presents a number of safety and environment issues. Typically, in the abandonment process, all production and surface wellbore casings along with conductor barrels and cement liners have to be removed to a depth of two meters below the surface. 
     A previous method for such removal required a large scale excavation of soil from around the existing wellbore. In order to do this, line location companies needed to be brought in to determine locations of any existing oil, gas and/or utility lines. Proper safety practices typically require that a very large area be excavated to allow a welder and an assistant to descend into the area to the required depth to cut the existing steel casings and cement liners. This cutting of the casing is done using a cutting torch. 
     Typically, the casing is cut horizontally and then vertically to remove the outer layer. Any cement present then has to be removed using either a jackhammer or sledge hammer. This allows access to secondary steel casings that are cut using the cutting torch again. 
     Throughout this process, a source of ignition, the cutting torch, is being used in an area wherein there is a possibility for the presence of explosive or flammable gases or liquids. This type of work environment may be referred to as a hot work area. A significant safety threat is inherent for the personnel in a hot work area and is further exasperated through the use of a cutting torch or any other heat based cutting tool. 
     One previous attempt at overcoming this issue was to provide a different type of tool consisting of a rotatable tube or hose that would be lowered inside the casing and then rotated about the central longitudinal axis. 
     More particularly, U.S. Pat. No. 8,820,396 provides an ultra-high pressure (UHP) cutting device for insertion into a wellbore for cutting the casing of the wellbore from within the wellbore. The cutting device of the &#39;396 patent comprises a UHP hose connector for connection with a UHP hose in communication with a fluid source; a rotatable UHP tube with a top end in fluid communication with the UHP hose connector and a bottom end opposite the top end; a rotating means in operational communication with the UHP tube for rotating the UHP tube during operation of the cutting device; and a cutter head in fluid communication with the bottom end of the UHP tube. 
     SUMMARY 
     Issues continue to exist with cutting devices for insertion into a wellbore. Particularly, previous cutting devices using UHP hoses, such as provided in the &#39;396 patent, require a complex system of connectors to effectuate the rotatable movement of the UHP hose. Thus, a need continues to exist for cutting devices using UHP hoses that are simpler in construction therefore less likely to fail.

The cutting head may vary between the first embodiment cutting device  10 A and the second embodiment cutting device  10 B and as such will be described in greater detail below with respect to each embodiment  10 A,  10 B. 
     As depicted in  FIG. 1 , cutting device  10 A includes an upper end  22  and a lower end  24 . Lower end  24  is configured to be inserted into a pipe  26  that is intended to be cut below the surface of ground  28 . A longitudinal axis  30  extends from the upper end  22  to the lower end  24  centrally within pipe  26 . Additionally, tubular support member  14  extends centrally along longitudinal axis  30  such that the inner bore  16  has an equal radius to all points within the inner surface of support member  14 . 
     Motor  12  is configured to drive a plurality of gears so as to effectuate the revolution of UHP hose  20  around the longitudinal axis  30 . In one version, the UHP hose  20  stays in substantially one position and revolves in unison with support member  14  which rotates about the axis  30  (See  FIG. 6A  and  FIG. 7A ). In another version, the UHP hose  20  revolves about the axis  30  while wrapping itself around the outside surface of tubular support member  14  (See  FIG. 6B  and  FIG. 76 ). Hose  20  includes its own axis  31  which is offset from central axis  30 . In one embodiment, a portion of the hose axis  31  is parallel to the longitudinal axis  30 . In another particular embodiment, the entirety of the hose  20  is offset parallel the longitudinal axis  30 . 
     In one embodiment, motor  12  is positioned above a circular disk or support plate  32  which has a diameter larger than the diameter of pipe  26  that is to be cut. Disk plate  32  includes an upwardly facing top surface  34  spaced apart from a downwardly facing bottom surface  36 . A circular edge  38  bounds the top surface  34  and the lower surface  36 . The perimeter of circular edge  38  depends on the diameter of disk plate  32 ; however, in one embodiment, the perimeter is substantially continuous and uninterrupted around the entire disk plate  32 . Disk plate  32  may further include an inner circular edge  40  defining a vertical through aperture extending from the first surface  34  to the second surface  36 . The central aperture is formed so as to define the disk plate  32  as a substantially annular planar plate. The upper surface  34  of disk plate  32  in between outer edge  38  and inner edge  40  creates a space upon which motor  12  is supported. In one particular embodiment, motor  12  is offset from longitudinal axis  30  so as to be positioned above the top surface  34 , disk plate  32  and not intersect the longitudinal axis  30 . In one embodiment, motor  12  is a hydraulic motor. 
     The aperture in disk plate  32  defined by inner edge  40  receives therethrough the tubular support member  14 , the abrasive feed line  18 , and the UHP hose  20 . A collar  42  is operatively connected to motor  12  adjacent the inner edge  40  of disk plate  32 . Collar  42  receives UHP hose  20  and tubular support member  14  therethrough. Collar  42  positions UHP hose  20  in an offset manner from longitudinal axis  30  so that no portion of UHP hose  20  intersects or is coaxial with longitudinal axis  30  of cutting device  10 A. In one particularly embodiment, collar  42  is fabricated from a substantially rigid material so as to be strong enough to support and carry the load of the tubular support member  14  extending therethrough. 
     Collar  42  is configured to rigidly secure the supportive member  14  therein. Additionally, the UHP hose  20  is secured in place in an eccentric manner relative to longitudinal axis  30 . The eccentric position of the hose  20  refers to the hose  20  not having its axis  31  (i.e., UHP hose axis  31 ) or other part placed centrally along longitudinal axis  30  Collar  42  is substantially concentric with longitudinal axis  30 . Thus, when motor  12  is turned on and in a drive mode, the collar  42  is driven by the motor and rotates about the longitudinal axis  30 . Additionally, the tubular support member  14  is also rotated around axis  30 . The UHP hose is carried by the collar  42  and positioned outside (and effectively carried by) the supportive member  14  so as to revolve around the longitudinal axis. Note: other embodiments are envisioned in other version in which the UHP hose may wrap around the tubular support member  14  and those alternatives are addressed in  FIG. 6B  and  FIG. 7B  (as well as  FIG. 9B  and  FIG. 10B  for device  10 B). 
     Tubular support member  14  includes an upper first end  44  and a lower second end  46 . Tubular support member  14  includes a rigid cylindrical sidewall  48  extending from the first end  44  to the second end  46 . In one embodiment, the cylindrical sidewall  48  is fabricated from metal and is substantially rigid material so as to provide structural integrity to the cutting device  10 A when the cutting head is located down within pipe  26  to be cut below the ground surface  28 . Cylindrical sidewall  48  includes an outer surface  50  ( FIG. 4 ) and an inner surface  52  ( FIG. 4 ) defining the central bore  16 . Along the length of the tubular support member  14 , the UHP hose  20  is positioned externally of the outer surface  52  along all points of the tubular support member  14 . In another embodiment, there may only be a portion of the UHP hose positioned externally of the outer surface  52  of tubular support member  14 . The abrasive feed line  18  is positioned internally within the bore  16  offset from the inner surface  50  of cylindrical sidewall  14  along the longitudinal length of the tubular support member  14 . Stated otherwise, a slight gap is formed between abrasive feed line  18  and the inner surface  52  of cylindrical sidewall  48  tubular support member  14 . A cutting head  54  is connected with the lower second end  46  of tubular support member  14 . 
       FIG. 2  depicts that tubular support member  14  defines a longitudinally extending channel  56  along its outer surface  50 . UHP hose  20  may reside within channel  56  along the longitudinal length of tubular support member  14 . In one embodiment, channel  56  has an arcuate cross-section complementary to that of the radius of curvature of the exterior surface of UHP hose  20 . However, it is understood that channel  56  may have differing cross-sections so as to not be complementary to that of UHP hose  20 . Furthermore, tubular support member  14  may not include a channel formed on the outer surface  50  thereof such that UHP hose  20  may be positioned externally to outer surface  50  and freely hang in slight contact or at a slight offset from tubular support member  14 . In each instance, commonality is in the fact that the UHP hose  20  revolves around the longitudinal axis  30  and is exterior to the outer surface  50  of tubular support member  14  and not located within the central bore such that no portion of UHP hose  20  is able to rotate about longitudinal axis  30 . 
     A collar  58  and a flange  60  rigidly connected with cylindrical sidewall  48  near lower second end  46 . Collar  58  is a substantially annular member extending around the outer surface  50  of cylindrical sidewall  48  and defines an arcuate cutout  82  to define a portion of channel  56 . Flange  60  is an annular member extending around the outer surface of cylindrical sidewall  48  and includes an arcuate cutout  84  complementary to that of channel  56 . Flange  60  may further include a plurality of through holes extending from the top surface of flange  60  therethrough to the bottom surface of flange  60  eccentric and spaced apart offset from longitudinal axis  30  adapted to receive screws or other fasteners therethrough to connect flange  60  with portions of cutting head  54 . While collar  58  and flange  60  are spaced apart from each other in a longitudinal manner, it is contemplated that other embodiments may only include flange  60 . 
       FIG. 2  depicts further components of cutting head  54  that effectuate the cutting of pipe  26  below the ground surface  28  while revolving UHP hose  20  about the longitudinal axis  30  while remaining, at least partially, exterior to outer surface of tubular support member  14 . With continued reference to  FIG. 2 , cutting device  54  located at the lower end  24  of cutting device  10 A includes a nipple  62 , a threaded couple  64 , a rigid body  66 , a focus tube  68 , an annular plate  70 , and a connector  72 . 
     As depicted in  FIG. 2  and  FIG. 3 , a first end  74  of nipple  62  threadably connects with a lower terminal end  76  of UHP hose  20 . The tubular body of nipple  62  is positioned within the lower end of channel  56  below UHP hose  20 . The body of nipple  66  is positioned in the channel so as to extend through the arcuate cutout of collar  58  and the arcuate cutout of flange  60 . The lower second end  78  of nipple  62  threadably connects with rigid body  66  at a bore  80  and is vertically aligned but offset from longitudinal axis  30 . In one embodiment, the radius of curvature associated with the outer surface of nipple  62  is complementary to that of the arcuate cutout  82  formed and defined by collar  58  which is aligned with channel  56 . In this instance, the arcuate cutout  84  formed by flange  60  is complementary to the outer surface of nipple  62 . Collar  58  and flange  60  engage and support nipple  62  so as to brace the same against forces of the UHP tube as it revolves about longitudinal axis  30  during the cutting of pipe  26  below ground  28 . 
     Threaded couple  64  is rigid a hollow body member including threads at both ends that define a bore therethrough and is substantially centered about longitudinal axis  30 . Threaded couple  64  extends into the bore  16  adjacent the lower end  46  of cylindrical sidewall  48  on tubular support member  14 . Threaded couple  64  is coaxial and aligned with longitudinal axis  30  and fluidly couples with the abrasive feed line  18  within the bore  16 . In one embodiment, portions of the threaded couple  64  may engage inner surface  52  of tubular support member  14 . A threaded upper end  86  of threaded couple  64  may threadably connect with the lower end of feed line  18 . However, other connections are entirely possible. The lower threaded end  88  of threaded couple  64  threadably couples with a central hole  90  on rigid body  66 . Central hole  90  is aligned coaxial with longitudinal axis  30 . This effectively enables abrasive feed line  18  to be coaxial along the length of longitudinal axis  30 . Stated otherwise, abrasive feed line  18  is not offset from longitudinal axis  30 . 
     Rigid body  66  includes an annular top surface  92  and a bottom surface  94 . A generally cylindrical sidewall  96  extends between the top surface  92  and the bottom surface  94 . Focus tube  66  is oriented perpendicular to longitudinal axis  30  so as to extend through an aperture formed in and extending through the cylindrical sidewall  96  of rigid body  66 . Annular plate  70  includes an annular top surface  98  spaced apart from an annular bottom surface  100  and a cylindrical sidewall  102  extending therebetween. The annular top surface  98  contacts the bottom surface  94  of rigid body  96 . In one embodiment, a central aperture  102  extending from the bottom surface  100  to the top surface  98  of annular plate  70  is aligned coaxial and centered with longitudinal axis  30 . The diameter of annular plate  70  is larger than that of rigid body  66 . However, the vertically aligned thickness or height of annular plate  70  is less than that of rigid body  66 . Annular plate  70  may be utilized in some embodiment to center the cutting head within the pipe  26  to be cut. Aperture  104  receives fastener  72  therethrough which includes a threaded top end  106  to threadably connect with rigid body  66 . Fastener  72  includes a stepped out portion  108  which has a similar diameter to that of aperture  104  formed in annular plate  70 . Fastener  72  extends along the longitudinal axis  30  and intersects the same and includes an enlarged head having a diameter greater than the diameter of aperture  104  preventing the fastener  72  from passing therethrough. The enlarged head of fastener  72  is positioned outwardly and below the lower second surface  100  of annular plate  70 . While not shown, it is entirely possible for a second annular or circular plate to be attached to the rigid body  66  above the focus tube  68 . In one instance, the second plate connects with a bracket located near the bottom end of the tubular support member  14 . Both annular plates cooperate to center the device within the pipe to be cut, which is helpful in the event the tubular support member  14  ever is bent. 
     Focus tube  68  is positioned intermediate the top surface  92  and the bottom surface  94  of rigid body  66 . In one embodiment, focus tube  68  is located approximately midway between the top surface  92  and the bottom surface  94 . However, other vertical positions of the focus tube  68  relative to the rigid body  66  are envisioned. Focus tube  68  includes a portion thereof that is embedded within rigid body  66  and retained at a shoulder. Additionally, focus tube  68  includes a portion that extends outwardly in a cantilevered manner from a rigid connection with the cylindrical sidewall  96  of rigid body  66 . In another embodiment, the focus tube  68  extends outwardly in a cantilevered manner from the rigid body  66 . However, in this alternative example, there is no rigid connection established therebetween so as to enable the focus tube to slideably fit and move in a transverse direction relative to rigid body  66 . This may effectuate the adjustment of focus tube  68  so as to enable the offset from the pipe  26  to be cut to be optimized. Optimizing the offset depends on the pressure within UHP hose  20  and feed line  18 . Fluid pressure exiting the focus tube  68  is what cuts pipe  26 . In one embodiment, the length of focus tube  68 , particularly the exposed portion of focus tube  68  that is not embedded within rigid body  66 , has a transversely aligned length that is less than the radius of plate  70  relative to axis  30 . In other embodiments, the focus tube  68  may have a transversely aligned length that is greater than the diameter of plate  70  such that the outermost end of focus tube  68  is the widest portion of the cutting head  54 . Alternatively, the diameter of plate  70  may have the largest outer diameter of cutting head  54  as shown on  FIG. 2 . and  FIG. 3 . 
       FIG. 4  depicts an assembled cross-section of the cutting device and the lower end  46  of tubular support member  14 . When assembled, the UHP hose  20 , the nipple  62 , and the rigid body  66  define a conduit for which UHP fluid can flow through the UHP hose  20 , then through the nipple  62  then into a vertically aligned bore  110  in operative communication with nipple  62 . Bore  110  is vertically aligned and offset from longitudinal axis  30 . A lower region of bore  110  may act as a well to trap some portions of fluid moving through hose  20 . An outlet  112  to bore  110  is aligned perpendicularly (i.e., transverse) thereto and in fluid communication with the bore  114  defined by focus tube  68 . The outlet  112  is positioned above the bottom of bore  110  acting as a well. The outlet  112  is defined by a jewel or gem  115 , sometime diamond or sapphire, which is able to withstand the immense pressure of the fluid moving through the outlet  112 . When UHP fluid flowing through UHP hose  20 , nipple  62 , and bore  110  exits outlet  112  into bore  114  of focus tube  68 . UHP fluid intersects the longitudinal axis  30  in a perpendicular manner. Stated otherwise, UHP fluid never flows coaxial the longitudinal axis  30 . The UHP fluid movement is offset parallel to longitudinal axis  30 , and the only time UHP fluid intersects longitudinal axis  30 , it is in a perpendicular manner when in the focus tube  68 . 
     With continued reference to  FIG. 4 , the abrasive feed line  18  extends coaxial with longitudinal axis  30  such that a significant portion of the flow of abrasive fluid moving along feed line  18  is coaxial with longitudinal axis until the abrasive fluid flows through threaded couple  64  and into the bore  114  so as to mix with the UHP fluid in the focus tube  68  in a mixing region which acts a venturi region  113 . The venturi mixing region  113  enables the high pressure fluid to pull the abrasive down along line  18  and outwardly through bore  114 . Thereafter the mixed UHP fluid and abrasive fluid exit the bore  114  of the focus tube  68  at outlet  116 . 
     Mixture of the UHP fluid and the abrasive fluid exiting the bore have a sufficiently high pressure and abrasion combination so as to effectuate a cut to the pipe  26 . In one embodiment, the pressure may exceed 40,000 psi so as to be suitable for cutting both cement and stainless steel pipes  26 . The pressure may be controlled by computer module that can be supplied with the device  10 A,  10 B. The computer module may further include at least one non-transitory computer readable storage medium having instructions encoded thereon that when executed by one or more processors inside the computer module, implement operations to effectuate the cutting of the pipe  26  by revolving UHP hose  20  around the outside of tubular support  14 . The operations may include driving the motor  12  as determined by the set of instructions at a desired speed or revolution. The operations may further include revolving the UHP hose around the outside of the tubular support  14  in a manner determined by the instructions contained on the at least one non-transitory computer readable storage medium. Operations may further include effectuating cutting the pipe  26  through the combination of UHP fluid and abrasive fluid exiting the focus tube  68  at a pressure and speed determined by the instructions encoded on the at least one non-transitory computer readable storage medium. 
       FIG. 5 - FIG. 10  depict varying operational views of device  10 A having cutting head  54  attached to the lower end  24  thereof. The cutting device  10 A effectuates the cutting of pipe  26  along a cut line  118 . When the pipe  26  is cut along cut line  118 , it is severed into two sections. An upper section of pipe  26 A may be removed from the ground  28  and the lower section of pipe  26 B may remain subsurface or below the ground surface  28  and can be capped in order to seal the pipe  26  safely within the ground. The cutter head  54  uses a combination of abrasive fluid and ultrahigh pressure liquid to effectuate the cut of pipe  26  along cut line  118 . 
       FIG. 5  and  FIG. 8  depict the cutting head  54  in a first position, which may also be referred to as a home position or a neutral position or a first position or a starting position (or something to a similar effect). The focus tube  68  is near the inner surface of pipe  26  and is offset a close distance from the inner surface of pipe surface  26  where the cut line  118  is to be established. Typically the cut line  118  is located in a range from about 4 feet to about 8 feet below ground surface  28 . However, other distances are entirely possible. In order to establish the distance that the cut line  118  is below the ground surface depends on the length of the tubular support member  14 . Thus, if the cut line  118  needs to be deeper below the ground surface  28 , a longer tubular support member  14  can be utilized. Thus, as seen in  FIG. 1 , symbolic break lines  120  are depicted so as to not limit the length of tubular support member  14  insofar as it may vary depending upon the required depth of the pipe to be cut at cut line  118 . 
     With continued reference to  FIG. 5  and  FIG. 8 , when the cutting head  54  is in the home position, abrasive fluid may be fed through feed line  18  and ultrahigh pressure liquid may be fed through UHP hose  20 . The mixture of abrasive fluid and UHP liquid or fluid occurs inside rigid body as depicted in  FIG. 4 . The combination of the mixed UHP fluid and abrasive material exists the outlet  116  on focus tube  68  and directed towards the inner surface of pipe  26  at cut line  118 . As the fluid begins to contact and cut pipe  26  at cut line  118 , the motor  12  effectuates the revolution of UHP hose  20  around the longitudinal axis  30 . This in turn causes the focus tube  68  to move around the inner surface pipe  26  along cut line  118 . 
       FIG. 6A  and  FIG. 9A  depict a one-half revolution of UHP hose  20 . Stated otherwise, the UHP hose  20  has revolved about 180° or half way wrapped around the longitudinal axis  30 . In this half-revolution position, cut line  118  extending through pipe  26  would have an approximate radius of curvature of about 180°. Near the half way position, revolution of UHP hose  20  remains substantially straight and elongated relative to tubular support member  14 . The fixed collar  42  effectuates the substantial stationary relative position of the hose  20  to the support member  14 . During the rotation of tubular support member  14 , the UHP hose  20  remains within the channel  56  defined by the outer surface  50  of cylindrical sidewall  48  on tubular support member  14 . Thus, in one instance, the arcuate curvature of channel  56  may include large enough sidewalls to stabilize the UHP hose  20  to remain the channel during the revolution of the hose  20  around axis  30  when the device  10 A is cutting the tube  26  along cut line  28 . 
       FIG. 6B  and  FIG. 9B  depict an alternative version that may include different components but would also operate within the scope of the present disclosure utilizing a one-half revolution of UHP hose  20 . Stated otherwise, in this alternative version the UHP hose  20  has revolved about 180° to be partially or half way wrapped around the tubular support member  14 . In this half-wrapped position, cut line  118  extending through pipe  26  would have an approximate radius of curvature of about 180°. Near the half way position, revolution of UHP hose  20  approximates 180° about the outer surface of tubular support member  14 . During the revolution of UHP hose  20 , the UHP hose  20  may exit the channel  56  defined by the outer surface  50  of cylindrical sidewall  48  on tubular support member  14 . Thus, in this instance, the arcuate curvature of channel  56  may include shallow sidewalls to encourage and enable the UHP hose  20  to leave the channel during the revolution of the same when the device  10 A is cutting the tube  26  along cut line  28 . More particularly shown at  FIG. 9 , the one-half revolution or the one-half wrap of UHP hose  20  around the outer surface  50  of cylindrical sidewall  48  is depicted generally at  122 . 
     As depicted in  FIG. 7A  and  FIG. 10A , the motor  12  may continue to revolve the UHP hose  20  around longitudinal axis  30  by remaining in a fixed relative position to tubular support member  14  so as to complete a 360° revolution of the UHP hose  20  around axis  30  while tubular support member  14  is rotating. This effectuates a full 360° cut of cut line  118  of pipe  26 . When the full revolution  124  of hose  20  has occurred around the longitudinal axis  30  carried by tubular support member  14 , still no portion of the UHP hose  20  intersects the longitudinal axis  30  of device  10 A. 
     As depicted in  FIG. 7B  and  FIG. 10B  (which correspond to the alternative version of  FIG. 6B  and  FIG. 96 ), the motor  12  may continue to revolve the UHP hose  20  around the outer surface  50  of tubular support member  14  so as to complete a 360° revolution of the UHP hose  20  around tubular support member  14 . This effectuates a full 360° cut of cut line  118  of pipe  26 . The 360° wrap or the full revolution wrap of hose  20  is indicated generally at  124 . When the full revolution  124  of hose  20  has wrapped around the outer surface  50  of tubular support member  14 , still no portion of the UHP hose  20  intersects the longitudinal axis  30  of device  10 A. 
     With continued reference to  FIG. 5 - FIG. 10 , a method of use for the cutting device  10 A may include a method of cutting a pipe, such as pipe  26 , comprising the steps of inserting a distal and (the second end  24 ) of a pipe cutting device, such as device  10 A,  10 B, into a pipe  26  wherein the cutting head  54  is located near the distal end  24 . Thereafter revolving the UHP tube or hose  20  around the longitudinal axis  30  while remaining exterior to outer surface  50  of a tubular support member  14  carrying the cutting head while the cutting head moves about a longitudinal axis  30  of the device  10 A,  10 B wherein the UHP hose  20  does not rotate about axis  30 . The step of revolving the UHP hose  20  around the outer surface of the tubular support member  14  occurs simultaneous to the pressurized fluid flowing along the UHP hose  20  parallel to longitudinal axis  30 . Stated otherwise, as the UHP hose  20  revolves around axis  30 , no portion of the fluid flow moving therethrough is coaxial to longitudinal axis  30 . The fluid exits UHP hose  20  near the second end  76  and enters nibble  62 . Thereafter, the UHP fluid moves through the vertically aligned bore of nipple  62  in a manner that is parallel and offset to longitudinal axis  30 . The UHP fluid then enters bore  110  which is vertically aligned and coaxial with that of nipple  62 . The UHP fluid exits the bore  110  in cutting head  54  through a transversely aligned outlet  112  that is offset from longitudinal axis  30 . The UHP fluid exits the outlet  112  and crosses the longitudinal axis in a perpendicular manner. Near longitudinal axis  30 , the abrasive fluid flowing through feedline  18  is mixed within the bore  114  that is transversely aligned perpendicular to axis  30 . Thereafter, the combined and mixed abrasive fluid and ultra-high pressure fluid exits bore  114  at outlet  116  and is directed towards the inner surface of pipe  26  which is intended to be cut along cut line  118 . The ultra-high pressure fluid and abrasive fluid mixture is able to cut through the pipe regardless of the pipe material construction, which is typical concrete or metal.

     For the methods of use detailed in  FIG. 6B  and  FIG. 9B  (as well as  FIG. 16B  and  FIG. 19B  introduced below), this embodiment or another embodiment may provide wrapping the UHP hose at least 180° around the outer surface  50  of the elongated member  14 . This embodiment or another embodiment may provide wrapping the UHP hose about 360° around the outer surface of the elongated member in the wrapped second position. With continued reference to this version utilizing the wrapping of hose  20 , subsequent to the steps of cutting pipe  26 , entire device  10 A may be removed from pipe  26 . After removing the device  10 A, which is still in the fully wrapped position  124 , the device  10 A may be unwound so as to return the UHP hose  20  back to the home position. Alternatively, the unwinding of UHP hose  20  from the wrapped position  124  back to the home position may occur within the tube  26  prior to the removable of device  10 A from tube  26 . In this instance, after the cut has been made, the device  10 A may be unwound so as to return to the home position and the device  10 A removed from the pipe  26  in the home position. 
     For the version of the device depicted in  FIG. 6A  and  FIG. 9A , subsequent to the steps of cutting pipe  26 , entire device  10 A may be removed from pipe  26 . The hose  20  will remain inside channel  56  during the removal of the device from pipe  26 . After the device  10 A has been removed from the pipe  26 , a machine may be positioned above the ground surface near the top end of the first section  26 A of pipe  26  and can be rigidly connected thereto. Connection of the machine (not shown) to pipe  26 A is used to extract the top section  26 A from the ground. In one scenario, there is no need to dig into the ground near the surrounding areas of the top section  26 A of pipe  26 . However, it is contemplated that to assist the removal of top section  26 A, an excavator or shovel may be used to dig away portions of the earth or the ground to ease the removal of top section  26 A. The bottom section  26 B which remains in the ground may be capped to completely seal off pipe  26  below the ground surface. Capping of lower section  26 B of pipe  26  may be done with a plug or other cap device that effectuates a permanent seal therewith. Permanent seal of the cap to the lower section  26 B may be welded or permanently adhered or connected in other known manners. Thereafter the space above the capped section of pipe  26 B, which was previously occupied by the top section  26 A, may be backfilled with earthen material. The ground may be leveled so as to leave no visible signs of the underground capped section of pipe  26 B above the ground. 
       FIG. 11  depicts the second embodiment of cutting device  10 B which includes some similar components to that of cutting device  10 A wherein the similar components are identified by similar reference numerals and are not repeated herein for brevity. Cutting device  10 B differs from cutting device  10 A in that it includes a differing cutting head  126 . 
     As depicted in  FIG. 12 ,  FIG. 13 , and  FIG. 14 , cutting head  126  of cutting device  10 B includes a generally rectangular rigid body  128 , a lower annular plate  130 , a threaded couple  132 , an elbow  134 , a focus tube  133 , a second threaded couple  138 , an extension tube  140 , and a fastener  142 . 
     Rectangular rigid body  128  includes an upwardly facing top surface  144  opposite a downwardly facing bottom surface  146 . Rectangular rigid body  128  includes four sidewalls extending from the first surface  144  to the second surface  146  at right angles thereto and at right angles relative to each other. Body  128  defines a first longitudinally extending bore  148  which is coaxial with longitudinal axis  30 . In one particular embodiment, bore  148  is centered relative to the first surface  144  and the second surface  146  such that the sidewalls of rigid body  128  are all equal relative their longitudinal axis  30 . The longitudinal bore  148  extends fully through rigid body  128  from the first surface  144  to the second surface  146 . A transverse second bore  150  is defined by rigid body  128  and extends from a first sidewall  152  fully transverse through rigid body  128  to a second sidewall  154 . Transverse second bore  150  has a diameter that is larger than the diameter of the longitudinally extending first bore  148 . The transverse second bore  150  is centered along a transverse axis  156  perpendicularly intersects longitudinal axis  30  within rigid body  128 . Rigid body  128  may further define a slot  158  in open communication with the longitudinal first bore  148  and the transverse second bore  150  such that the slot  158  interrupts the first sidewall  152  and interrupts the top surface  144  of rigid body  128 . 
     Rigid body  128  may further define a plurality of laterally extending bores  160  which are formed as through holes that laterally extend through a third sidewall  162  rigid body  128 , wherein the third sidewall  162  is parallel and offset from a fourth sidewall  164 . The third sidewall  162  and the fourth sidewall  164  are perpendicularly intersect and form corner unions with the first sidewall  152  and the second sidewall  154 . The lateral bores  160  are configured to receive a fastener, such as a screw, therethrough which engages in a frictional interference fit an outer surface of a collar  137  operatively connected with tube  133 . When assembled, the collar  136  slideably received within a portion of transverse second bore  150 . This enables the focus tube to be slideably adjusted along transverse axis  156  to provide a desired offset from the inner surface of pipe  26  to be cut by abrasive fluid and ultrahigh pressure fluid moving through focus tube and the extension tube  140 . 
     With continued reference to  FIG. 12 ,  FIG. 13 , and  FIG. 14 , an upper threaded end  168  of first couple  132  is threadably connected with lower end  76  of UHP hose  20 . Lower end  170  of couple  132  is threadably connected with elbow  134 . First couple  132  defines a bore therethrough for fluid from UHP  20  to move therethrough when the couple  132  is threadably connected with lower end  76 . The bore  172  of couple  132  extends from first end  168  to threaded second end  170 . 
     Tube  133  is oriented transversely and includes a cylindrical body  174  defining an opening  176  aligned with the bore  172  of couple  132  within the elbow  134 . Elbow  134  defines a transversely extending bore  178  that receives the cylindrical body  174  of tube  133  therethrough. When the cylindrical body  174  of tube  133  is disposed within the transverse bore  178  of elbow  134 , the opening  176  is positioned vertically below the longitudinally extending bore  172  of couple  132 . An open fluid communication is established through the bore  172  such that ultrahigh pressure liquid or fluid may flow from hose  20  through the couple  132  into the bore  180  defined by cylindrical tube  174  of focus tube  133 . A threaded forward end  182  on cylindrical body  174  is configured to mate with a gland nut  135  and collar  137  and an additional coupler  145 . An insert  139  has a transversely tapered opening that is in fluid communication with the end  184  of tube  133 . Insert  139  enables high pressure fluid to flow into a venture mixing chamber  141 . 
     Extension tube  140  is oriented transversely and includes a cylindrical body  184  that extends through second couple  138  along the transverse second axis  156 . The extension tube  140  is aligned with cylindrical body  174  of tube  133  along second axis  156  and is retained in place by fastener  142  within the second bore  150  of rigid body  128 . The cylindrical body  184  of extension tube  140  defines a bore  186  and is in open fluid communication with bore  180  ( FIG. 14 ) of focus tube  133  via the venture mixing chamber  141 . The open fluid communication of bore  186  with bore  180  effectuates the transition of UHP fluid from focus tube  133  to the extension tube  140  while drawing abrasive through line  18  which is also in fluid communication with mixing chamber  141 . More particularly, fluid flows through bore  180  defined by cylindrical body  174  through mixing chamber  141  where it draws abrasive out from line  18  and the mixture flows through bore  186  defined by cylindrical body  184 . Similar to the previous embodiment, within cutting device  10 B, the ultrahigh pressure fluid is never flowing along longitudinal axis  30 , rather when the ultrahigh pressure fluid is within UHP hose  20 , it is offset parallel to axis  30 . After passing through the elbow  134 , the UHP fluid only intersects longitudinal axis  30  in a perpendicular manner and is never coaxial therewith. The abrasive fluid moving along abrasive line  18  extends centrally in a coaxial manner along longitudinal axis  30  and is mixed with UHP fluid inside rigid body  128  in chamber  141  by moving through a hole  188  formed in second couple  138 . The lower end  88  of couple  64  connects with rigid body  128  to create an open fluid communication of the couple  64  with the hole  188  of second couple  138  through bore  148 . 
     While not shown, it is entirely possible for a second annular or circular plate (in addition to plate  130 ) to be attached to the rigid body  128  above the focus tube  133 . In one instance, the second plate connects with a bracket located near the bottom end of the tubular support member  14 . Both annular plates ( 130 , and the second annular plate) cooperate to center the device within the pipe to be cut, which is helpful in the event the tubular support member  14  ever is bent. 
       FIG. 14  depicts a mixing bowl  147  located within couple  138  and held in position by a tapered member  149  defining a transversely aligned bore that receives tube  140  therethrough. The mixing bowl  147  is in direct fluid communication with venture chamber  141 . Mixing bowl includes a tapered wall  151  that narrows to an opening for moving the mixture of UHP fluid and abrasive through tube  140 . 
     When the tube  133  and the extension tube  140  are connected together, they may move transversely along the axis  156  and may be secured in place by fasteners extending laterally through bores  160  on rigid body  128 . This effectuates and enables an operator or user to vary the offset distance of the end of the extension tube  140  relative to the inner surface of the pipe  26  to be cut. Thus, if the pipe has a narrower diameter, the focus tube and extension tube  140  would be adjusted to move the outer end  190  of extension tube  140 . Alternatively, if the pipe  26  to be cut has a larger diameter, the outer end  190  of extension tube  140  would be moved in a direction opposite that as previously described. The directional sliding movement of the outer end  190  is represented by movement arrows A in  FIG. 13 . This indicates that the outer end  190  may slide along transverse second axis  156 . 
       FIG. 15 - FIG. 20  depict similar positions of the UHP hose  20  as it revolves around the longitudinal axis  30  while remaining outside of tubular support member  14  as indicated above with reference to  FIG. 5 - FIG. 10 .  FIG. 15  and  FIG. 18  depict cutting device  10 B in the first position, which also may be referred to as the neutral position or the home position. In this scenario, the cutting head  126  may be oriented in a manner such that the end  190  of extension tube  140  is aligned with a cut line  118  of pipe  26 . As the UHP fluid moving through hose  20  and the abrasive fluid moving through feed line  18  mix within rigid body  128  exits the outer end  190  of extension tube  140 , it is directed towards the cut line  118  and cuts the same into the first section of pipe  26 A and the second section of pipe  26 B to be capped and left in the ground. 
       FIG. 16A  and  FIG. 19A  depict the one have revolution position wherein the collar  42  effectuates the fixed relative relationship of the hose  20  and the tubular support member  14 . As the tube member  14  rotates (as driven by motor  12 ), the hose  20  is carried by collar  42  so as to revolve around the axis  30 . The motor is capable of driving the revolution from the home position to the one have revolution position. The motor may drive the revolution from the one half position to a full revolution position, or alternatively, the motor may reverse directions and drive the revolution from a one half revolution position to a reverse one have revolution position (i.e., from 180° to −180°). 
       FIG. 16B  and  FIG. 19B  depict the alternative version where the hose  20  is wrapped around the member  14  to accomplish to revolution of hose  20  around axis  30 . More particularly, the half wrap  122  of the hose  20  makes a 180° revolution about the outer surface  50  of tubular support member  14 . Motor  12  may continue to drive cutting head  126  to move it along the cut line  118  fully therearound such that, as shown in  FIG. 17B  and  FIG. 20B , the full wrap or full revolution  124  of UHP tube is effectuated around the outer surface  50  of tubular support member  14 . Thus, device  10 A and  10 B operate in a similar manner, but may be accomplished with different styles of cutting heads located at the lower end  46  of tubular support member  14 . 
       FIG. 21 - FIG. 23  depict a drive assembly utilized to effectuate the revolution of UHP hose  20  in cutting device  10 B. The drive assembly includes hydraulic motor  12 , a 90° worm gear reducer  200 , a reducer shaft  202 , a gear reducer mount  204 , a pinion gear  206 , a split clamp  208  of the collar  42 , the top plate  32 , a spur gear  210 , a middle plate  212 , a hub  214 , a bearing  216 , and a bottom plate  218 . 
     Shaft  202  includes an upper end  220  in operative communication with the hydraulic motor being positioned within the 90° worm gear reducer  200 . Hydraulic motor  12  drives shaft  202  via worm gear reducer  200 . Longitudinal axis of shaft  220  is offset parallel to longitudinal central axis  30  of device  10 B. Shaft  202  extends through an aperture  222  formed in gear reducer mount  204 . The gear reducer mount  204  is located above the upwardly facing top surface  34  of top plate  32  above an aperture  224  formed extending through the top surface  34  of top plate  32 . Aperture  224  is offset from the inner edge  40  such that the aperture  224  is eccentric to central aperture  226  defined by inner edge  40 . Pinion gear  206  extends through aperture  224  is in direct communication with a lower end  228  of shaft  202 . Pinion gear  206  rotatably mates with gear  210 . 
     Middle plate  212  is generally annular in shape and includes an upwardly facing top surface  230  and a downwardly facing bottom surface  232 . Middle plate  212  further includes an outer perimeter edge  234  and an inner edge  236  defining a central aperture  238 . Inner edge  236  is interrupted by an arcuate cutout  240  defining a smaller second aperture  242 . Aperture  242  is sized to receive the lower end of pinion gear  206  therein. When assembled, the middle plate  212  is closely adjacent the top plate  32  such that the lower surface  236  of the top plate engages the upwardly facing top surface  230  of the middle plate  212 . The central aperture  226  of top plate  32  has a smaller diameter than the central aperture  238  of middle plate  212 . The spur gear  210  is positioned within the central aperture  238  of the middle plate  212 . 
     An outer perimeter  244  of spur gear  210  is closely adjacent the lower end of pinion gear  206  residing in the cutout aperture  242 . Spur gear  210  is rigidly connected to collar  42 . Accordingly, when hydraulic motor  12  drives shaft  202  which rotates the pinion gear  206 , the spur gear  244  is rotated about longitudinal axis  30  to effectuate the revolutional movement of the UHP hose  20  which is held in place by an eccentric edge  246  of spur gear  210  (and the collar  42 ). Spur gear  210  is positioned above the hub and bearing  214 ,  216  within the central aperture  238  of the middle plate. The hub and bearing  214 ,  216  effectuate movement of the spur gear  210  in response to driven movement of pinion gear  206 . The hub and bearing  214 ,  216  are located centrally about longitudinal axis  230  and are retained within the bearing retainer  252 . Lower plate  218  includes an upwardly facing top surface  248  which mateably engages the downwardly facing lower surface  232  of middle plate  212 . Lower plate  218  further includes a downwardly facing bottom surface  250 . The bearing retainer  252  may extend downwardly from the bottom surface  250  of lower plate  218 . Bearing retainer  252  retains bearing  216  therein. Additionally, a channel  254  may be formed in upwardly facing top surface  248  configured to receive an O-ring or gasket seal. 
     Lower support plate  218  may also qualify as a centering device  258  in accordance with one aspect of the present disclosure. A centering device utilizing lower support plate  218  may be used with various aspects of either this disclosure or other disclosures which require a tool to be centered within a pipe  26  or within another cylindrical body. Thus, while the centering device  258  encompassed by the lower plate  218  is shown herein with respect to cutting device  10 B, it is to be understood that any utility tool on the down hole end of a tubular support member could be centered within the pipe  26  utilizing the centering device  258 . 
     Thus, centering device  258  may include plate  218  and a plurality of angled support arms  260  extending from the bottom surface  250  of plate  218 . In one embodiment, the centering device  258  may utilize three support arms  260 A,  260 B,  260 C oriented 120° apart from each other and viewed from above along the longitudinal axis. When viewed from the side, as depicted in  FIG. 22 , the three tapered support members  260 A,  260 B,  260 C each includes an upper end  262  and a lower end  264 . The upper end  262  is rigidly connected with the bottom surface  250  of plate  218 . The lower end of  264  of support member  260  may be connected with a collar  266  which is concentric about longitudinal axis  30 . In one embodiment, an angle  268  is defined between the tapered support  260  and the bottom surface  250  of bottom plate  218 . The angle  268  may be in a range from about 10° to about 80°. In one particular embodiment, the angle  260  is in a range from about 45° to about 60°. In another particular embodiment, the angle  260  is 60°. The upper end  262  is positioned radially outward a further distance from longitudinal axis  30  relative to lowered end  264 . Accordingly, the combination of the tapered supports  260 A,  260 B,  260 C allow the device  10 A,  10 B or another utility down hole tool device to be centered within pipe  260 . The tapered supports act as a centering cone to effectuate the centering of device  10 A,  10 B or another device relative to longitudinal axis  30 . 
     With continued reference to  FIG. 21 ,  FIG. 22 , and  FIG. 23 , centering device  258  is not limited to use strictly with the cutting heads  54 , 126 . It may be used to center any type of utility tool in the pipe  26  or tube when the utility tool at least partially is inserted therein. The centering device  258  may further provide that the first member  260 A include a first edge  261 A angled relative to the longitudinal axis  30  of the pipe  26  or tube. The second member  260 B may include a second edge  261 B angled relative to the longitudinal axis  30 . The third member  260 C may include a third edge  261 C angled relative to the longitudinal axis  30 .

Additionally, the first and second edges  261 A,  261 B are angularly contact the pipe  26  or tube in a slanted alignment. In one example, the first support member  260 A is spaced about 120° from the second support  260 B member relative to the longitudinal axis  30 . 
     The bottom plate  218  is rigidly connected with respective upper ends of the first, second, and third edges  261 A,  261 B, and  261 C. The first, second, and third edges  261 A,  261 B, and  261 C are sized to contact a portion of an upper circumferential edge  263  of the pipe  26  or tube. The lower ends  264  of support members  260 A,  260 B, and  260 C are positioned radially outward of the inner edge  265  ( FIG. 21 ) defining a central aperture  267  ( FIG. 21 ) relative to the longitudinal axis  30 . This enables and positions the an upper ends  262  on the first edge  261 A or the first support  260 A remain exterior to the pipe  26  or tube in response to revolution of a portion of the utility tool inside the pipe or tube. 
     With continued reference to  FIG. 22  and  FIG. 23 , the cutting device  10 B or  10 A may also be referred to as a device for effecting the pipe  26  or tube when the device  10 A,  10 B is at least partially inserted therein. The device  10 A,  10 B includes the elongated support member  14  including first and second ends, wherein the support member  14  is oriented similar to the longitudinal 30 axis of the pipe or tube. A utility tool, such as cutting head  54  or  126 , is coupled near the second end of the elongated support  14  adapted to be inserted into the pipe  26  or tube, and the utility tool performs a function that effects the pipe or tool (in this case cut the pipe, however other functions are entirely possible, such as clean the pipe or paint the pipe or weld the pipe). The centering device  258  is near the first end of the elongated support  14  for centering the device relative to the pipe  26  or tube. The centering device  258  includes the first edge  261 A that is angled between 10° and 80° relative to the longitudinal axis  30  and the first edge  261 A is adapted to contact at least a portion of an inner circumferential edge  263  of the pipe  26  or tube. The first edge  261 A on the centering device includes a first end (near  262 ) and a second end (near  264 ), wherein when the centering device  258  centers the device within the pipe  26  or tube, the first end of the first edge  261 A is exterior to the pipe  26  or tube and the second end of the first edge  261 A is interior to the pipe  26  or tube. The second edge  261 B on the centering device is spaced radially from the first edge  261 A relative to the longitudinal axis  30 , wherein the second edge  261 B is angled between 10° and 80° relative to the longitudinal axis and the second edge is adapted to contact at least a portion of the inner circumferential edge  263  of the pipe  26  or tube, wherein the second support includes a first end and a second end, wherein when the centering device centers the device within the pipe or tube, the first end of the second edge  261 B is exterior to the pipe or tube and the second end of the second edge  261 B is interior to the pipe or tube. The third support  260 C includes a first end and a second end, wherein when the centering device centers the device within the pipe or tube, the first end of the third edge  261 C is exterior to the pipe or tube and the second end of the third edge is interior to the pipe or tube. In one particular example, the first and second supports  260 A,  260 B on the centering device  258  are at an angle in a range from 30° to 60° relative to the longitudinal axis  30 . 
     The first ends  262  of the first support  260 A and the second support  260 B are both positioned along an imaginary circumferential curve associated with circumferential edge  263  defined by X 2 +Y 2 =R 2 , wherein a R is a first radius of inner surface  269  of the pipe  26  or tube relative to the longitudinal axis  30  and a second radius of the first ends  262  of the first and second supports  260 A,  260 B relative to the longitudinal axis  30  is greater than the first radius so as to position the first ends  262  exterior from the inner surface  269  of the pipe  26  or tube. 
     In one example the motor  12  revolves UHP hose  20  or tubing around the elongated support member  14  including an outer end that is positioned radially outward from the first ends of the first support and the second supports on the centering device. However, other embodiments of the present disclosure may provide a motor that effect revolutionary movement of a portion of the utility tool while an outer end of support  14  that is positioned radially outward from the first ends  262  of the first support  260 A and the second support  260 B on the centering device. 
     As depicted in  FIG. 21 ,  FIG. 22 , and  FIG. 23 , the centering device  258  is generally conical in shape. More particularly, the centering device  258  is shaped in an inverted frustoconical configuration. 
       FIG. 24  represents a drive system in accordance with another aspect of the present disclosure utilized on cutting device  10 A. A majority of the features of the drive system depicted in  FIG. 25  are similar to those depicted in  FIGS. 21-23 , except that it does not have a centering device utilizing the tapered supports identified above. Rather, the centering device utilized with cutting device  10 A has an annular collar or cylindrical member  270  which would have an outer diameter that is slightly less than the pipe  26  to be cut. Accordingly, the collar nests within the pipe so as to effectuate a centering of the drive device and the cutting device  10 A about longitudinal axis  30 . It is envisioned that the embodiment of the drive system utilizing the centering collar  270  shown in  FIG. 24  is best utilized with smaller diameter pipes in a range from about four to six inches. The centering device  258  shown with respect to  FIG. 21 ,  FIG. 22 , and  FIG. 23  is envisioned to be best utilized on pipes having a diameter larger than about six inches. 
       FIG. 25  depicts and alternative annular plate  231  which is connected to the cutting head so as to center the same when the cutting head is located within a pipe  26  to be cut. Plate  231  include one or more edges  233  that define cutout regions  235  that interrupt the perimeter  237  of plate  231 . Plate  231  may further define longitudinally extending holes  243  extending fully through plate  231 . Together, the cutout regions  235  and holes  243  form passageways for fluid and debris to pass through when the cutting device  10 A or  10 B is in its operational mode. The passage of debris through the passageways enables the high pressure fluid that cuts pipe  26  to flow way from the cutting head to prevent clogging. Plate  231  may further include adjusting screws  245  spaced in intervals around the pate  231 , specifically around the perimeter  237 . The screws  245  may be manually adjusted to contact the inner surface of pipe  26  so as to center the plate  231  relative to the pipe. 
       FIG. 26  is a side elevation view of cutting head  126  depicting that coupler  64  has a smaller diameter than slot  158  so as to enable the coupler  64  to slide into and out of the slot  158 .  FIG. 27  depicts a centering collar  247  extending downwardly from bearing retainer  252 . Centering collar  247  may substitute the centering device  258  form  FIG. 21  when smaller diameter pipes need to be cut. For example, when a 4″ pipe needs to be cut, the centering collar  247  may be inserted into the pipe to center the cutting assembly therein. Accordingly, centering collar  247  may have an outer diameter that is slightly less than or equal to about four inches to enable the same to slide within a four inch inner diameter pipe. The centering collar  247  defines radially extending holes  249 . The radial holes  249  are design to receive centering screws therethrough (similar to set screws  245 ). When the device needs to cut a pipe with a smaller diameter, such as an outer diameter of two inches, the centering collar  247  may be slipped over the outside of the tube to be cut. Then, centering screws may be threaded through holes  249  to center the cutting assembly inside the pipe to be cut by screws contacting the outer surface of the pipe when the centering collar  247  is positioned radially exterior therefrom. 
     Additionally, other embodiments of the cutting heads  54 , 126  are to be fabricated in a manner that includes at least two focus tubes for directing the mixture of UHP fluid and abrasive towards the inner surface of the pipe to be cut. For example, the cutting heads  54 , 126  could each have two focus tubes rotatable at least 180° in opposite directions at the same or near the same time. This could effective reduce the cutting time for the machine in half (as opposed to a single focus tube performing a complete 360° turn. 
     Also, various inventive concepts may be embodied as one or more methods, of which an example has been provided. The acts performed as part of the method may be ordered in any suitable way. Accordingly, embodiments may be constructed in which acts are performed in an order different than illustrated, which may include performing some acts simultaneously, even though shown as sequential acts in illustrative embodiments. 
     All definitions, as defined and used herein, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and/or ordinary meanings of the defined terms. 
     The indefinite articles “a” and “an,” as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.” The phrase “and/or,” as used herein in the specification and in the claims (if at all), should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc. As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e. “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of,” or “exactly one of.” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law. 
     As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc. 
     In the claims, as well as in the specification above, all transitional phrases such as “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” “holding,” “composed of,” and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases “consisting of” and “consisting essentially of” shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures. 
     An embodiment is an implementation or example of the present disclosure. Reference in the specification to “an embodiment,” “one embodiment,” “some embodiments,” “one particular embodiment,” or “other embodiments,” or the like, means that a particular feature, structure, or characteristic described in connection with the embodiments is included in at least some embodiments, but not necessarily all embodiments, of the invention. The various appearances “an embodiment,” “one embodiment,” “some embodiments,” “one particular embodiment,” or “other embodiments,” or the like, are not necessarily all referring to the same embodiments. 
     If this specification states a component, feature, structure, or characteristic “may”, “might”, or “could” be included, that particular component, feature, structure, or characteristic is not required to be included. If the specification or claim refers to “a” or “an” element, that does not mean there is only one of the element. If the specification or claims refer to “an additional” element, that does not preclude there being more than one of the additional element. 
     In the foregoing description, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be implied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed. 
     Moreover, the description and illustration of the preferred embodiment of the disclosure are an example and the disclosure is not limited to the exact details shown or described.
