Patent CA-2110394-A1 (CA)
Inventor: KROSCH KARL
IPC: B29C43/04
Filed: 1993-03-12
Abstract: PCT No. PCT/DE93/00225 Sec. 371 Date Nov. 30, 1993 Sec. 102(e) Date Nov. 30, 1993 PCT Filed Mar. 12, 1993 PCT Pub. No. WO93/19917 PCT Pub. Date Oct. 14, 1993.The recycling of used polyurethane foam is made possible by a process in which the starting material is first dried to a moisture content of 2 to 4% and is then filled into a multi-part mold (16, 17, 18) that defines the molded part (32). The parts of the mold (16, 17, 18) are then, with generation of the necessary compression pressure of below 20 N/mm2, pressed together and locked. These molds (16, 17, 18) that are subject to the compression pressure are heated in a tunnel furnace (20) so that the molding material reaches a temperature of approximately 130 DEG  C. After a predefined holding time, the molds (16, 17, 18) can be opened under pressure and the molded parts (32) can be removed. Molded parts (32) with a thickness of 42 mm and of corresponding size have been produced successfully with this process. Instead of the molds (16, 17, 18), it is also possible that a two-part tool is used. Also possible is the use of turntables (14, 41, 44), whereby the pressing and holding time can be shortened by adding an accelerator. The process, which comprises only one pressing step, enables an approximately continuous operation.

Inventor: GOTTLIEB MARK
IPC: F02N11/08
Filed: 1994-01-11
Abstract: An automatic vehicle starter in which a temperature sensor may sense a temperature of the engine.  The vehicle starter may then remotely crank a starter motor of the vehicle.  The duration of time that the starter motor is cranked will be based on the sensed temperature.  In this way, a vehicle can be cranked for an appropriate amount of time without requiring any tachometer sensing operation.          Also, to insure that the vehicle has been properly started, after a signal to remotely start the vehicle is transmitted, a first battery voltage is measured.  Then, the ignition to the vehicle is turned on so that all turned on accessories will have power supplied thereto.  A battery voltage is then again measured, this battery voltage representing the battery voltage with a load applied thereto from the turned on accessories having power supplied thereto.  The vehicle is then automatically started.  The battery voltage is then continuously measured and, if it determined that the battery voltage falls below a predetermined value, it will indicate that the vehicle has stalled.  The vehicle can then automatically be restarted to insure proper starting or can be turned off.

IPC: A61F2/06
Filed: 1992-11-06
Abstract: A system and closure (22) for determining the position of a blood vessel (26) via a percutaneous puncture (24) and for sealing the percutaneous puncture in the blood vessel. The system includes an introduces sheath (28, 28') and associated positioning de-vice.(200, 300, 400, 600), a hemostatic puncture closure (22), and a deployment instru-ment (20). The positioning device (200, 300, 400, 600) enables the introduces sheath (28) to be positioned at a desired position within the vessel (26). The deployment instrument (20) includes a tubular carrier (100) storing the closure (22). The carrier (100) has a dis-tally located free end (104) to be extended via an introducer (28, 28') through the punc-lure (24) and its associated tract (24A). The closure (22) comprises a radiopaque rigid anchor (32, 32'), a compressed collagen plug (30), and a thin filament (34) connecting the two in a pulley-like arrangement. The carrier (100) ejects the anchor (32, 32') through the introducer (28, 28') and puncture (24) and then draws it against the free end of the introducer. The instrument (20) and introducer (28, 28') are then withdrawn to-gether to pull the anchor against the tissue contiguous with the puncture inside the ar-tery. Further withdrawal draws the plug (30) out of the carrier (100) into the puncture tract (24A), whereupon the plug (30) moves with respect to the anchor (32, 32') into en-gagement with the outside of artery wall to seal the puncture or incision (24). A tension-ing device (116, 118, 120, 122) limits the force applied to the filament (34).  The carrier (100) also includes a tamper (130) which is used to mechanically deform the plug (30) within the tract (24A). Once positioned hemostasis occurs rapidly, thereby locking the closure (22) in place.

Patent CA-2136460-A1 (CA)
Inventor: TOPPER ROBERT T
IPC: A23G9/28
Filed: 1994-11-23
Abstract: A reciprocating piston with an integral valve moves in a first direction within a cylinder to pressurize viscous material contained therein, such as ice cream or the like, thereby pushing it out of a dispensing nozzle located at one end of the cylinder while simultaneously extracting viscous material from a collapsible container into the other end of the cylinder by suctioning the material from the container.  When the piston moves in a second direction, the integral valve opens to allow the piston to pass through the previously suctioned viscous material then within the cylinder.  The dispensing nozzle includes a normally closed, spring-biased valve opened by the force of the pressurized material, closing of the valve being assisted by a transient suction force occurring as the valved piston begins to move in the second direction through the material. Suctioning the material from the collapsible container, as opposed to compressing the container to expel the material, is preferable when the material contains entrapped gas, as is the case with ice cream, since repeated compression of such containerized material can diminish its quality.
Patent CA-2138946-A1 (CA)
Inventor: COUTTS GRAEME F
IPC: F16K17/04
Filed: 1993-05-27
Abstract: A pressure relief valve (10) is described which includes an apertured ball valve element (28), which is spring-loaded, and which is rotatably and axially mounted in the valve bore so that when an over-pressure situation arises fluid forces the ball (28) off a ball valve seat (50) against a spring force (40) and causes the ball valve (28) to rotate such that the aperture (32) in the ball valve (28) connects the inlet bore (20) and outlet bore (22) of a valve housing (16) so that fluid can flow through the pressure relief valve (16). When pressure at the inlet falls beneath a predetermined value, the spring force (40) forces the ball (28) to rotate and move back against the valve seat (50), thus closing the valve (10). With this arrangement there is minimal pressure exerted on the valve housing (16) and the valve (10) will operate with a back-pressure up to 50 % of the inlet pressure. This means that much smaller bore outlet piping can be used with savings in weight and, consequently, cost. For example, 3 in. piping may be used instead of 8 in. or larger piping for the equivalent rated valves.
