Title: Method and System for the Injection Molding of Plastic Articles Utilizing a Fluid Compression Unit
Inventor: HENDRY JAMES WATSON
IPC: B29C45/17
Filed: 1991-05-16
Abstract: A method of and apparatus for injection molding plastic articles. The apparatus includes a resin injection nozzle, a mold having an injection aperture and a mold cavity for receiving molten resin from the nozzle. The gas compression unit (37') includes a gas booster (58) which pressurizes a first charge of gas to the pressure setting of a pressure switch (71). The gas receiver (72) stores the first charge of pressurized gas at a pressure level within a predetermined range of pressures. A first fluid pressure redu-cing valve (74) reduces the pressure of the gas as it is communicated from the fluid receiver (72) to an orifice in the mold to an acceptable level for molding the article. A second fluid pressure reducing valve (79) allows a relatively low holding pressure in the article sufficient to complete the article and hold any thick sections of the article from sinking. The gas compression unit (37') is capable of servicing several injection molding machines and corresponding molds when a plurality of such first and second pres-sure reducing valves (74, 74', 74", 79) are provided.

IPC: B60R21/2165
Filed: 1994-01-25
Abstract: CONTROLLED DEPLOYMENT DRIVER'S SIDE AIR BAG     ABSTRACT OF THE DISCLOSURE         A driver's side vehicle air bag, including releasable stitching for controlled deployment, comprises circular front and rear panels joined at their peripheries.  A central inlet opening in the rear panel is flanked by parallel lines of releasable stitching  to  form  a  central  region  and  lateral  lobes. Interruptions of the stitching adjacent the inlet opening produce passageways for direct flow of inflation gas to the lateral lobes.  The air bag is folded in accordian folds perpendicular to  the  stitch  lines,  and  thereafter  in  packing  folds perpendicular to the accordian folds.   During the inflation, outward deployment of  the  front panel  is  retarded by the stitching and the lateral lobes inflate to create a broad frontal surface.  The stitches release prior to full inflation.

Patent CA-2116075-A1 (CA)
Inventor: BROWN WILLIAM J
IPC: A47F7/00
Filed: 1994-02-21
Abstract: A sheet restraint for a sheet shipping rack includes a first elongated tube rotatably mounted on a second elongated tube.  The second tube has U-shaped member secured to each end to capture the first tube on the second tube while allowing the first member to rotate relative to the second member.  A resilient elongated sheet engaging member is secured to the first member.  A pair of spaced pins are mounted on the first member and engageable with the U-shaped member to limit rotation of the first member about the second member so that the rotational path of the sheet engaging member and first tube is limited.  The engaging members on the second tube are slideable mounted to spaced standards at the front of a rack.  In this manner the front restraint moves toward the base into engagement with the outermost sheet of a stack of sheets on the rack to maintain the sheets as an integral pack.  During shipment, the movement of the sheets and rack by the transportation forces and any space resulting from such movement is taken up by the front restraints as it moves downwardly toward the base. To unload the sheets from the rack the front restraint is urged upward away from the base and removable from the standards at the front of the rack.

Title: Cutting clamp for connecting an insulated connecting wire
Inventor: STEINER EWALD
IPC: H01R4/24
Filed: 1992-11-02
Abstract: The clamping slot (3), produced by shearing, of the insulation piercing connecting device (1) extends in a jagged shape. One of the two clamping legs is deformed at the end of its foot in such a way that its free end is shortened or lengthened. As a result, the clamping legs are offset with respect to one another in the region of the clamping slot and are partially constricted or widened. The pressed-in connecting wire (6) is thus securely held in the clamping slot (3).
