Title: Bedding materials for animals
Inventor: BALLARD LARRY
IPC: A01K1/015
Filed: 1994-08-26
Abstract: ABSTRACT OF THE DISCLOSURE A degradable, reusable, partially synthetic and partially non-synthetic bedding material for animals includes a plurality of flexible monofilaments formed from a blend of a thermoplastic polymer and starch. An effective amount of at least one transition metal salt may also be added to enhance ultraviolet and/or thermal degradation. The partially synthetic animal bedding has an appearance, texture and sound very similar to that of natural straw, but can be cleaned and reused repeatedly. The partially synthetic straw-like material is inert as far as digestibility and is degradable when exposed to sunlight and dry heat, and is biodegradable and compostable thereby providing for relatively easy disposal.

Abstract: CO2 jet spray cleaning apparatus (10) that monitors CO2 snow plume characteristics. The present invention is a CO2 jet spray cleaning system (10) that comprises a holding tank (12) for containing liquid CO2 (15), a spray nozzle (14) coupled to the holding tank (12), a valve (13) coupled between the holding tank (12) and the spray nozzle (14), and a temperature sensor (11) coupled to the nozzle (14) for sensing the temperature of a plume (16) of CO2 that is sprayed by the nozzle (14) and for providing a signal indicative thereof. The system (10) may also comprise a display (17) coupled to the temperature sensor (11) for displaying the temperature of the plume (16) of CO2 to an operator, or an alarm (18) coupled to the temperature sensor (11) for alerting an operator that the temperature of the plume (16) of CO2 has risen to a predetermined level. Either the displayed signal or the alert signal indicates that the quality of the plume (16) has diminished and that the liquid CO2 (15) in the holding tank (12) should be replenished. The present CO2 jet spray cleaning system (10) and CO2 snow plume sensor (11) provide an indication of the proper CO2 snow characteristics to an operator so that the system (10) cleans in a proper manner.

Patent CA-2142579-A1 (CA)
Inventor: COLUMBUS PETER S
IPC: C08K7/02
Filed: 1995-02-15
Abstract: A cross-linkable water-based wood adhesive comprised of a critical mixture of from 0.10 to 0.75 by weight of a water-soluble, high-viscosity thickening agent polymer such as hydroxyethylcellulose, 0.05 - 0.40% by weight of a defoamer to dissipate foam quickly during manufacture, 25.00 to 45.00% by weight of solids of a self-cross-linking polyvinyl acetate polymer (treated with N-methylolacrylamide) dispersed in water, the polymer having a molecular weight of about 30,000 to about 300,000, 1.00 - 3.00% by weight of a plasticizer/coalescing agent such as 2,2, 4-trimethyl-1,3 pentanediol monoisobutyrate, 0.50 to 1.00% of an acidic catalyst, such as aluminum chloride, 4.00 to 12% by weight of fine particle-size wood fibers (soft or hard wood fibers or a mixture of both) and 0.10% by weight of a preservative.The viscosity of this adhesive gel will "break-down" when its container, e.g. a squeeze-bottle or flexible tube is finger-pressed resulting in a sufficiently low viscosity to allow for easy extrusion from the small orifices, approximately 0.10 inch diameter or a rectangular slit opening such as approximately 1/16" wide by 5/16"long of the adhesive application tips attached to such squeeze-bottles and flexible tubes. When pressure is released after the desired amount of adhesive flows out of the container, the adhesive quickly reverts very closely to its original gel state so that it will not "run" on vertical surfaces nor "spill" when used as a general purpose wood adhesive. This adhesive has sufficient wet tack to hold two pieces of wood together while still allowing repositioning of the pieces of wood before drying. In addition, since this product contains real wood fibers, its dry film is stainable and easy to sand.
Patent CA-2143560-A1 (CA)
Title: Sterile occlusion fasteners and instrument and method for their placement
Inventor: FOGELBERG MARK
IPC: A61B17/122
Filed: 1995-02-28
Abstract: A clip, clip applier and method for ligating a tissue structure is provided. The applier has a two stage actuation. In the first stage, a tissue structure is positioned into the jaws of the clip applier The jaws close and lock to a preset force to compress and temporarily occlude the tissue structure. If satisfactorily positioned, the second stage is initiated in which a clip is advanced through the shaft of the clip applier in a closed position. At the distal end of the clip applier, the clip is opened slightly to capture the pre-compressed tissue structure, and is placed over the structure. The clip is then dissociated from the business end of the instrument. Preferably the clip comprises two leg members disposed in close proximity to one another joined from opposing directions by a connecting element. The connecting element restricts separation of the leg members with opposing spring members so as to provide substantially uniform parallel deflection of the leg members from each other.

Title: Downhole gas-liquid separator for wells
Inventor: WEINGARTEN JEAN S
IPC: B01D17/00
Filed: 1994-04-20
Abstract: A downhole gas-liquid separator (36) for multiphase fluid producing wells (10) includes a tubular member (39) with a spiral baffle (42) disposed therein and a duct (48) including an inlet (50) disposed adjacent the discharge end (46) of the spiral baffle (42).

Gas is drawn off at the discharge end (46) of the spiral baffle (42) and discharged into the wellbore annulus (26) while liquid and a small amount of gas pass on through the separator (36) and the production tubing (22) to the surface. The spiral baffle (42) may be disposed in the wellbore between the distal end (23) of the production tubing string and the point of entry (20) of gas and liquid into the wellbore. The separator (36) may inlcude a retrievable tubular body (80) inserted in a ported nipple (66) interposed in the tubing string (22).

Abstract: A low profile door handle having interior and exterior parts is disclosed. The interior part of the door handle comprises a body and a handle portion having upper and lower ends attached to the body. The handle portion has a top having a high area at its center and low areas at its upper and lower ends. The distance between the top of the handle portion and the body gradually and continuously decreases from the center to the upper and lower ends so that the top curves downward smoothly from the high area to the low areas. The contour of the body is similarly curved so that the door handle may be used in conjunction with horizontal blinds without interfering with operation of the blinds or creating a large bulge.

Abstract: L'invention concerne une composition d'amorce qui comprend une solution ou une dispersion de: (a) 2 % à 30 % en poids d'une résine filmogène; (b) 2 % à 80 % en poids d'un produit de réaction d'unépoxy silane et d'un amino silane. L'amino silane contient au moins deux groupes d'amines par molécule, et on le prépare (1) en mettant en contact un amino silane et un époxy silane dans des quantités telles que le rapport molaire de l'époxy silane et de l'amino silane dans le mélange de réaction soit inférieur à 1,8:1,0 et (2) on ajoute ensuite l'époxy silane supplémentaire au mélange de réaction de sorte que le rapport molaire de l'époxy silane et de l'amino silane soit au moins de 2:1 dans un solvant volatil. On a découvert que l'amorce de l'invention renforce la fixation d'un substrat non poreux, tel que du verre, sur un second substrat, notamment lorsqu'il est utilisé conjointement avec une colle "à durcissement rapide" se composant d'un prépolymère fonctionnel d'isocyanate et d'un dimorpholinodiéthyle éther. De plus, ces amorces peuvent être préparées plus facilement que les amorces qui nécessitent une "cuisson" du silane comprenant un produit de réaction d'un polyisocyanate et d'un ou plusieurs composés contenant du silane.

Title: Slag granulation
Inventor: FEATHERSTONE WILLIAM BARRY
IPC: B01J2/02
Filed: 1994-08-11
Abstract: A granulator for granulating molten material comprises a rotary atomiser to which the molten material is supplied. Without the assistance of fluid jets, the molten material is broken up into globules which are caused to pass through an air curtain containing entrained granules. This has the effect of accelerating the cooling rate of the globules to form granules and also of reducing the kinetic energy of the granules so that the length of their flight path is reduced thereby allowing the overall size of the granulator enclosure to be reduced.
