A powdered metal control plate is integrally formed with an external gear located within the ring gear, and the ring gear has two teeth with leading and trailing surfaces in simultaneous contact with corresponding trailing and leading surfaces on the external gear for preventing backup of the spool. The cable passes through a downstop pawl which pivots to engage a notch within the spool when the cable is fully extended, and in a modification a projecting end portion of the shaft is provided with a one-way anti-theft drive coupling. A torque limiting clutch as a one-piece powdered metal clutch cam which is integral with an eccentric drive cam, and an adjacent powdered metal clutch plate carries a set of wire springs which drive the clutch cam.

Title: Corrosion resistant high temperature contacts or electrical connectors and method of fabrication thereof
Inventor: BELL JAMES A E
IPC: C25D3/12
Filed: 1992-05-25
Abstract: CORROSION RESISTANT HIGH TEMPERATURE CONTACTS OR ELECTRICAL CONNECTORS AND METHOD OF FABRICATION THEREOF     ABSTRACT   The invention provides a composite material specifically adapted for use as high temperature corrosion resistant electrical connectors. A conductiblenickel-base substrate alloy having corrosion resistance, strength and creep resistance is used to hold shape at 200°C. An interlayer of substantially pure nickel is electrolytically plated over the nickel-base substrate. A noble metal surface isdiffusion bonded to the electrolytic nickel interlayer. The noble metal surface cannot be hardened by organic additives which accelerate corrosion at 200°C. Alternatively, if a copper-base substrate is used, a layer of wrought pure nickel is bonded to the substrate then a layer of electroplated nickel is used to overplate the wrought nickel and the copper-base substrate. A noble metal surface is then diffusion bonded to the electrolytic nickel layer.

Title: Extrudable polyvinyl alcohol compositions containing polyethylene oxide
Inventor: FAMILI AMIR
IPC: C08L71/02
Filed: 1992-10-09
Abstract: An extrudable polyvinyl alcohol composition useful for packaging and molding applications is prepared by melt blending polyvinyl alcohol and thermoplastic polyethylene oxide to provide a product which has improved pH stability and salt solution solubility. Useful extruded articles prepared from such compositions include films and containers.      A method for extruding the polyvinyl alcohol composition comprises: adding sufficient energy to the polyvinyl alcohol composition to both melt it and essentially eliminate the polyvinyl alcohol crystallinity in the melt, and simultaneously removing energy from the melt at a rate sufficient to avoid decomposition of the polyvinyl alcohol.      The thermoplastic polyethylene oxide may be added to the polyvinyl alcohol before the polyvinyl alcohol is melted and its crystallinity eliminated or blended with the thus thermally treated polyvinyl alcohol and then melt extruding the polyvinyl alcohol/polyethylene oxide blend.

Abstract: A drawbar assembly includes a self-locking bushing which is supported from the drawbar mounting bracket by a conventional nut and bolt fastener. Each end of the bushing includes radial line projections which bite into the mounting bracket and into a washer interposed between the nut and the bushing when the nut is threaded onto the bolt.  By capturing both bushing ends, the bushing cannot rotate to loosen the nut or wear against the mounting bracket and washer.  The bushing is formed as a single component with the radial line projections by a powdered metal process and hardened to provide wear resistance.  Dissimilar metals in the bushing and the drawbar at the pivotal connection reduce wear.

Title: Method of processing image data
Inventor: NAKAGAWA YOSHIHIRO
IPC: H04N1/23
Filed: 1992-12-21
Abstract: At a data output apparatus side, raster image information, which is obtained by means of performing an exclusive OR operation between raster image information on the preceding line and raster image information on the current line, is compression-processed in a raster direction and then transmitted to a data processing apparatus. In the data processing apparatus, the received image information is expansion-processed, an exclusive OR operation between image information after the expansion and image information on the preceding line is carried out, and a processing for recording and the like is performed taking the thus obtained information as the raster image information on the current line. Thus it is possible to provide a higher compression rate of the image information with a simple processing and to improve a processing speed.
