Patent CA-2192701-A1 (CA)
Inventor: SURINAK JOHN J
IPC: F16L37/26
Filed: 1996-12-11
Abstract: In a pitless well adapter, an adapter insert from which a flow pipe and pump depends, is normally vertically, slidably and removably held by wedge ribs in an adapter housing.  The top surfaces of the adapter insert and adapter housing are similarly formed such that sliding the adapter insert out of engagement with the adapter housing will enable the adapter insert to be deflected into the casing in a manner which will spare damage to the adapter insert.  The bottom surface of the adapter insert and the adapter housing are of matching contours so as to permit proper seating of the adapter insert in the adapter housing.  The uppermost portion of the wedge ribs are tapered to form a guide surface engageable with the adapter insert upon installation of the adapter insert in the adapter housing.
Patent CA-2193229-A1 (CA)
Title: Ball-contacting pad for sport shoe
Inventor: TIEFENBACHER KONRAD
IPC: A43B5/02
Filed: 1996-04-18
Abstract: A sport shoe having ball-contacting pads mounted thereon for increasing kicking performance without appreciably decreasing ball feel is disclosed. The pads include a top layer separated from a bottom layer by interconnecting elastic elements or webs. The top and bottom layers are substantially planar and elongate. The pad is arranged on the shoe so that when, for example, a soccer player kicks a ball, reaction forces from the impact will displace the top layer longitudinally, substantially parallel to the bottom layer, thus stretching the elastic interconnecting elements, storing potential energy. As the ball leaves the player's shoe, the reaction forces are diminished, and the potential energy in the interconnecting elements moves the top layer to again move longitudinally, but in an opposite direction. This return movement imparts a tangential force on a ball, thus enabling a player to kick the ball with substantial spin, a key tactic during many parts of a soccer game.

Patent CA-2199185-A1 (CA)
Inventor: CHRISTIAN GARY
IPC: H01H27/06
Filed: 1997-03-05
Abstract: A vehicle anti-theft device is disclosed. The anti-theft device provides a key operated switch that makes or breaks the electrical continuity of four electrical circuits. These electrical circuits are essential to the operation of the vehicle; therefore their discontinuity prevents vehicle operation. A lock housing carries a lock having a rotating spindle. The spindle carries a perpendicular dive pin which engages a bushing having a helix shaped groove in its interior surface. A tab-like raised key sliding in a keyway slot in the housing prevents the bushing from rotating. Therefore, rotation of the spindle creates art axial movement of the bushing. A male contact block, carrying four U-shaped solid contact pins may be extended by the axial movement of the bushing to engage a female contact block carrying eight female socket contacts which are connected to eight in-coming wires. When extended, each U-shaped pin creates electrical continuity between a pair of wires. When retracted, the four circuits are electrically discontinuous, and the vehicle operation is prevented

Patent CA-2206925-A1 (CA)
Title: Constant current needle annealing
Inventor: SCHOB GEORGE
IPC: H05B3/56
Filed: 1997-06-04
Abstract: A constant current annealing device for annealing a wire or surgical needle is disclosed. The device includes amplitude and time setting devices, such as thumb-wheel switches. A constant current source is connected to the current setting device. The constant current source is switchable, through a switch for example, in response to a timing signal to provide a constant current for a predetermined duration. A pair of spaced apart electrodes are clamped on the needle and a switching device is connected between the constant current source and the pair of electrodes. The voltage drop across the switching device varies to compensate for load variations, thus keeping the anneal current constant in the anneal ON mode. In the anneal OFF mode, where current is not provided to the needle, the switching device shunts a residual current away from the electrodes. The time setting device include a programmable logic controller (PLC) and a solid state relay to provide an accurate timing signal. A current measuring and monitoring device is connected to another PLC, which shuts down the annealing device after a predetermine number of alarms or after the constant current amplitude deviates by a predetermined amount.

Title: Forming solutions of cellulose in aqueous tertiary amine oxide
Inventor: QUIGLEY MICHAEL
IPC: D01D1/00
Filed: 1996-01-09
Abstract: A method is described for forming a solution of cellulose in a tertiary amine oxide (such as N-methylmorpholine N-oxide) and a non-solvent for cellulose (such as water). The method involves the preparation of a mixture containing excess non-solvent, and removing the excess by heating the mixture to a temperature in excess of the boiling point of the non-solvent at a predetermined sub-atmospheric pressure, and feeding the heated mixture into the introduction zone of a mixing chamber at the predetermined sub-atmospheric pressure, so as to cause flash evaporation of some of the excess non-solvent.  The mixture in the mixing chamber is then agitated by a rotor and transported through the mixing chamber whilst further evaporation of the non-solvent occurs. The cellulose solution thus formed is extracted from the mixing chamber, and the evaporated non-solvent withdrawn in cocurrent mode from the same end of the mixing chamber. Apparatus for carrying out the method is also described.

Title: Rolling membrane stent delivery device
Inventor: KUSLEIKA RICHARD S
IPC: A61F2/958
Filed: 1996-02-26
Abstract: A device for deploying radially self-expanded stents and other radially expandable stents includes an inner catheter (28, 82, 130, 142), an outer catheter (18, 88, 132, 146) surrounding the inner catheter, and a tubular stent retaining sheath (22, 92, 118, 150) formed of a rolling membrane. The sheath is doubled over upon itself to provide an inner sheath layer (46, 104, 120, 156) attached to the inner catheter, and an outer sheath layer (48, 108, 122, 162) attached to the outer catheter. The sheath layers extend along and surround a radially self-expanding stent (56, 102, 124, 160), to maintain the stent distally of the inner catheter and in a radially compressed, axially elongated state. Distally of the stent, the inner and outer sheath layers converge and are narrowed in the distal direction to define a tapered distal tip (26, 106, 128, 164). To release the stent, the outer catheter is moved proximally to roll the membrane away from its surrounding relation to the stent, whereupon the stent radially self-expands progressively, beginning at its distal end. When completely retracted after stent release, the sheath surrounds a distal region of the inner catheter, and can provide a protective layer between arterial tissue and a dilatation balloon (58, 110, 148) supported along the distal region. As an alternative, a stent formed of a recovery metal can be plastically deformed into a reduced radius state for delivery, which facilitates use of a more flexible stent retaining sheath. A  further alternative involves securing the sheath proximally of the dilatation balloon, so that sheath retraction leaves the dilatation balloon exposed, rather than covered by the sheath.
