Patent CA-2050001-A1 (CA)
IPC: A47F5/08
Filed: 1991-08-27
Abstract: A peg board hanger comprises two extents diverging at an acute angle which meet at a bight, the two extents being adapted to the approximately parallel to one side of a peg board.  Each extent extends from the bight toward a free end.  At each free end there is an extension curved through approximately 90° in a plane generally perpendicular to the longitudinal axis of the extent. Each extent is curved in the same sense.  The extension is dimensioned to pass through the peg board so that the free end is on the opposite side of the peg board from the extent.  The arrangement is such that when the hanger has the extensions passing through spaced holes in a peg board, the hanger cannot be easily detached by accidental vibrations.

Title: Plasticizing apparatus for use in an injection molding machine
Inventor: HEHL KARL
IPC: B29C45/62
Filed: 1991-10-01
Abstract: ABSTRACT PLASTICIZING APPARATUS FOR USE IN AN INJECTION MOLDING MACHINE          In the plasticizing cylinder the plasticized plastic material is transported by a rotating feed screw into a space which is in front of the feed screw and the plastic material is subsequently injected into the injection mold of the injection molding machine by an axial discharge stroke of the feed screw. During that stroke a backflow-preventing valve is effective to seal a high-pressure space from a low-pressure space, which contains the feed screw. The plasticizing cylinder is composed of a cylinder head, which always completely encloses the high-pressure space and the backflow-preventing valve, and a cylinder shank, which encloses the low-pressure space and the feed screw. Even when the feed screw is in its rearmost initial position will the high-pressure space not be adjoined by a joint which leads to the outside of the plasticizing cylinder so that the problems previously encountered in connec-tion with the sealing of the high-pressure space are avoided.

Abstract: A combination air cleaner/noise silencer consisting of a two piece housing having a series of converging-diverging venturi.  A conically-shaped cone directs the flow of air axially along and between a generally cylindrically shaped pleated paper type filter element.  Optionally, a perforated member positioned downstream of the filter element reflects induction noise back to the engine source and aligns the air stream into a nearly uniform and parallel flow so as to be accurately measured by a mass air flow sensor.  Both the perforated member and cone act to reflect engine generated induction noise back toward the engine.
Patent CA-2057919-A1 (CA)
Inventor: GREIFF PAUL
IPC: G01C19/5719
Filed: 1991-03-14
Abstract: A semiconductor chip gyroscopic transducer (10) is disclosed in which a semiconductor element (47) is supported in an outer element by a flexible linkage system which is in turn supported in a frame of semiconductor material (16) by another flexible linkage system which permits the element to vibrate about two axes relative to the frame. Balanced torque forces are provided by a system of buried (50, 52, 54, 56) and bridge (58, 60, 62, 64) electrodes. The stress and tension resulting from doping of these elements are released by a flexure beam (20, 22, 36, 38). The inertial mass of the inner element is balanced by formation in a central pit and on-chip electronics avoids the capacitive loading effects of long ru ns from high impedance sources. Flexure footings are integrated with the structure adding stability to flexures connecting the supported gyroscopic resonator element to the supporting structure, offsetting a rippling effect inherent in the oxide structure. Flexure grooves provide selective stiffness in the flexure. The bridge electrodes (58, 60, 62, 64) are additionally electrically isolated fo r electrical compatibility with gyroscope electronics.
