Patent CA-2143056-A1 (CA)
Title: Walk-Through Flat Barn Parlor
Inventor: HOPPMAN DAVID P
IPC: A01K1/12
Filed: 1995-02-21
Abstract: A walk-through flat barn parlor comprises a number of modular stalls for managing dairy cows.  Each module has a frame to which a pair of gates are mounted.  The axes of rotation for the gates make compound angles with the vertical such that the gates are biased by gravity to rotate from a closed mode to a ready open mode.  A control mechanism is actuated by a cable mechanism from a milking station to unlock the gates for automatic rotation by gravity from the closed mode to the ready open mode.  A cow walks to the ready open gates and pushes them to the closed mode, where she is constrained for milking.  After completion of milking, the farmer actuates the cable mechanism to unlock the gates and enable the cow to push them to an exit open mode.  When the cow has cleared the gates, they automatically rotate by gravity back toward the closed mode.  A pawl on a bar connecting the gates co-acts with the control means to enable the gates to rotate past the closed mode all the way to the ready open mode.  The cable means includes a reversing mechanism that enables the farmer to actuate the control mechanism in a consistent manner regardless of the side of the stall his milking station is located.

Patent CA-2146938-A1 (CA)
Inventor: SHENOY VIVECK N
IPC: D01F4/00
Filed: 1995-04-12
Abstract: In accordance with the present invention, it has been discovered that the stability of collagen fibers is altered upon treatment of a solution or dispersion of the collagen fibers with a chemical reagent for the inactivation of infectious agents. This fiber destabilization makes it difficult to formulate the collagen fibers to final product when the formulation contains an ingredient which alters the destabilized collagen fibers. Collagen fiber stability in a collagen dispersion can be controlled using either a physical fiber-stabilizing agent or a chemical fiber-stabilizing agent. The physical fiber-stabilizing agent is used to protect the stability of the assembled fibers, without providing for covalent bonding between fibrils which make up the fibers. The chemical fiber-stabilizing agent is used to provide covalent bonding between fibrils, whereby the fibers are stabilized. A stabilized dispersion of collagen fibers is achieved by the presence of a physical fiber-stabilization means comprising a polymeric material of the kind which is capable, at sufficient concentration, of causing collagen fibers to precipitate from solution. Preferred polymeric materials are water soluble or water miscible. Preferably the water soluble or water miscible polymeric material is biocompatible, such as a polyethylene glycol or derivatives thereof. A stabilized dispersion of collagen fibers is also prepared by using a chemical fiber-stabilizing agent which crosslinks fibrils within the fiber, stabilizing the fiber. A preferred method of stabilizing the collagen fiber produced from a solution ora dispersion of collagen treated with an agent for the inactivation of infectious agents is to stabilize the collagen fiber subsequent to the treatment, by using one of the physical or chemical fiber-stabilizing means.
Patent CA-2147063-A1 (CA)
Title: Tool for maintaining wellbore penetration
Inventor: LABONTE RAYMOND
IPC: E21B17/07
Filed: 1995-04-13
Abstract: A tool for connection in a wellbore drill string for maintaining penetration of a drilling bit attached to the drill string when the drill string becomes stuck or hung up during drilling operations. The tool has a telescoping outer member and innermember which form an annular chamber between them which contains a plurality of springs that are selected to provide a desired amount of contraction of the tool when a predetermined axial compressive load is applied through the tool to the drilling bit. The tool also includes interlocking splines on the outer member and the inner member which inhibit rotational movement of the outer member and inner member relative to each other, and the chamber is filled with hydraulic fluid which is pressurized to the hydrostatic pressure of the wellbore adjacent the tool by a floating piston which is movably located in the chamber. In operation, the tool contractswhen an axial compressive load is applied through the tool during drilling operations. If the axial compressive load is decreased due to sticking or hangup of the drilling string, the springs operate to extend the tool, thus maintaining a force on the drilling bit which causes the drilling bit to maintain an amount of penetration in the wellbore.
Patent CA-2147652-A1 (CA)
Title: Selectively actuatable lighter
Inventor: MCDONOUGH JAMES M
IPC: F23Q2/16
Filed: 1993-10-22
Abstract: A selectively actuatable lighter device (10) is disclosed which includes a body defining reservoir (12) for containing a com-bustible gaseous medium such as butane, and having a valve (20) arranged to be selectively actuated between a normally closed position and an open position which permits the exit of the gaseous medium.  Such lighter (10) can selectively produce sparks at a location (19, 22) proximate to the gaseous medium exit to ignite the gaseous medium. Such lighter device (10) embodies a resi-liently releasable valve actuator (14) which normally prevents actuation of the valve (22). The valve actuator (14) includes an inter-fering portion (14A) which is selectively movable to a position (figure 14) out of interference with an interfering portion (27) of the lighter body, so that the gaseous medium may be released and ignited by the sparks. Once the valve actuator (14) is depressed and released, it returns to its closed or latched position to prevent actuation of the valve to the open position. To "re-use" the ligh-ter, the valve actuator (14) must again be moved to an unlatched position so that the valve (22) can be actuated for subsequent ig-nition of the gaseous medium.

Title: Improved fumigation of particulate commodities
Inventor: WINKS ROBERT GORDON
IPC: A23L3/3409
Filed: 1994-06-15
Abstract: When fumigating a bulk particulate commodity stored in a top-vented vertical silo (10) by slowly passing a gas containing a low concentration of a gaseous fumigant through the bulk mass, differences between the temperature, Tg, in the bulk mass (11) and the ambient temperature, Ta, outside the silo cause a "chimney effect" within the silo, and possible unwanted dilution of the fumigant. The chimney effect also occurs in other top-vented storage structures containing particulate commodities.  To overcome the chimney effect, the fumigant-containing gas is supplied through a duct (18) to the base of the storage structure at a flow rate Qf(in m3 sec-1) determined by the relationship (I) where g is the acceleration due to gravity (approximately 9.8 m sec-2); Pa is the atmospheric pressure expressed in Pascals; Ra is the gas constant for air (= 287 J kg-1 K-1); T. is in K; Tg is also in K; R is a resistance factor (in Pascals sec m-2) which depends upon the nature of the commodity in the storage structure; and A is the horizontal cross-sectional area of the storage structure, in square metres. This technique can also be used to maintain effective fumigation of a plurality of storage structures in a storage facility, from a single source of gaseous fumigant.
