Filed: 1997-12-25
Granted: 2005-05-10
Abstract: A container (10) for storing two components separately and then mixing them prior to use includes a housing (12) having an opening (14) and a neck portion (16), a displaceable member (20), and a closure member (48). The housing (12) is formed with a first compartment (18) and a second compartment (38) intercommunicating at the neck portion. The displaceable member (20) has a partition wall (22) for sealing the neck portion (16). The displaceable member (20) is formed such that the partition wall (22) moves from a non-sealing position in which the first (18) and second (38) compartments intercommunicate to a sealing position in which the neck portion (16) is sealed. The displaceable member (20) also may feature at least one conduit for allowing introduction of a component through the opening into the housing. The closure member (48) seals the at least one conduit of the displaceable member and/or the opening of the housing (12). The displaceable member (20) may be moved by rotating, pushing or pulling and may be moveable by a portion exterior to the housing (12). The seal formed by the partition wall (22) of the displaceable member (20) may be reformable, i.e., capable of being resealed. A pre-packaged, single use, two compartment container (10) according to some embodiments of the invention have an unremovable closure member (12), an unreformable seal, an unfastenable closure member (48) after it has been removed or is constructed in a manner or of materials which allow only a single use. The two-compartment container (10) may also include a dosing assembly for dispensing a predetermined quantity of mixed formulation.

Abstract: An improved method and apparatus for extracting resin from plant material. Conventionally, plant resins, which are useful in many products, are extracted using chemical solvents, which may alter the extract, and may produce a byproduct or residue that may be unusable or problematic. The present invention overcomes these drawbacks by using cold water in a wash process to cause the resins to become brittle, while the remaining plant material becomes more flexible. Separation is accomplished using an extractor (10) having a washing chamber (12) with an open top (14) and a screen filter (16) disposed above a settling chamber (18). A collection bottle (24) is placed below a valve (22), and may include a filter (26) to separate resin particles from the solute. The washing chamber is first filled with cold water and then a quantity of plant material (P) is placed therein, followed by an ice layer (30). An agitator (32) is then actuated to mix the contents to separate the resins. The settled resin is thereafter captured by the filter (26) upon opening the valve (22).

Abstract: A method of gas liquefaction wherein the refrigeration to cool and liquefy an essentially water-free feed gas is provided by a single recirculating mixed refrigerant cycle in which refrigeration is provided by the vaporization of two mixed refrigerant streams of different compositions at a lower and higher pressure levels respectively. A lower pressure level vaporizing refrigerant cools the feed gas stream in a first cooling zone and a higher pressure level vaporizing refrigerant further cools and condenses the cooled gas in a second cooling zone to provide the final liquid product. The lower pressure level vaporizing refrigerant is provided by one or more liquids obtained by ambient cooling of compressed mixed refrigerant vapor. The vaporized lower pressure level refrigerant can be returned to the refrigerant compressor at a temperature below ambient, without further warming, and this cool refrigerant is compressed and combined with the vaporized higher pressure level refrigerant, which is returned at about ambient temperature.

Abstract: An indexable insert is located on a toolholder with reference to bearing surfaces on the insert and the toolholder which are proximate to the active cutting edge.  These bearing surfaces are internal to the peripheral (side) flanks of the insert. Location of the insert in the toolholder is substantially independent of the relation between the toolholder pocket sidewalls and the peripheral flanks of the insert, thereby eliminating sources of error from insert manufacture and pocket manufacture. The insert and toolholder have locating units disposed thereon adapted to matingly engage each other when the insert is placed in the toolholder. At least one of the locator elements has a bearing surface or surfaces that extends through 360° and resulting in less movement of the insert during use.

Abstract: Apparatuses for and methods of installing ear tags are provided. One embodiment of the invention is defined as an ear tag installation tool and which makes use of a pair of handle members (12, 14) which control the insertion of an inserting member (30) through an opening formed in the ear of an animal. The inserting member has attached to it a portion of the ear tag during the insertion process. The inserting member may be disposable and separate from the handle members after the insertion process is complete. In a second embodiment, the ear tag installation tool is an elongate tool having a handle (52) and a distal tip for receiving the inserting member. In a third embodiment of the invention, an ear tag installer (110) is provided which has some elements directly attached to the ear tag. The ear tag installer also includes a driving tool (60) which forces the inserting member (114) through the ear. In this third embodiment, the ear tag installation tools of the first and second embodiments can be used as preferred forms of the driving tool. In another embodiment of the invention, the elements of the third embodiment attached to the ear tag can be separately defined as a modified ear tag with inherent installation capability. In yet another embodiment, the distal ends of the handle members may be modified so that biasing forces are used to enhance the method of installing the ear tags.

Title: Method and device for the sequential supply of articles to be processed
Inventor: SEILER RICO
IPC: B65H29/60
Filed: 2002-08-16
Granted: 2010-10-05
Abstract: For allowing a reduction in the processing capacity to be accommodated without delay in a system, in which articles are supplied and transferred to an article processing device (8) from an article delivering device (4) in a regularly clock cycled supply stream, articles are not transferred to the article processing device when there is no processing capacity. Instead they are conveyed onwards along a return track (9) and are re-introduced into the supply stream at a return point (6) upstream of the transfer point (7). For each re-introduction of a returned article into the supply stream, a gap is produced in the supply stream in a gap formation point (5) upstream of the return point (6). For synchronizing returned articles and gaps, the length (in clock cycles) of the return track (9) is matched to the length (in clock cycles) of the supply track (3) from the gap formation point (5) to the return point (6) and to a time difference (in clock cycles) between a non-transfer and formation of a corresponding gap. The system is suitable in particular for supplying main products from a web-fed printing press to a stacking/packaging device where normal packages and peak packages are produced.  The main products are completed prior to being stacked and packed. In this application it is possible to operate the article supply regularly clock cycled although no separate processing device for producing the peak packages is provided and although no completed products are to be removed from the system.
