Title: Treating workpieces
Inventor: REEDMAN DAVID C
IPC: G05B19/18
Filed: 1987-10-27
Granted: 1994-08-09
Abstract: Abstract TREATING WORKPIECES        A system for identifying workpeices by scanning them and "reading" details of their configuration is adapted for applying a desired pattern of material in liquid form (e.g. ink) or in powder form (e.g. toner material or a hot melt adhesive) to the workpieces regardless of their location and orientation on a workpiece support (18, 118).  This is achieved by the pattern data (relating to the desired pattern) selected from a store being modified in accordance with positional data (relating to the location and orientation) obtained during scanning (Figure 2).  Where the applied material is liquid a suitable tool is a pen (152) or other liquid applicator: where ini powder form, a suitable tool is an electrostatic printer (36) e.g. an ionographic printer.

Abstract: A partially crosslinked thermoplastic elastomer composition excellent in the heat bondability is obtained by dynamically heat-treating (i.e., kneading in a molten state) a blend of a peroxide-crosslinking olefin copolymer rubber and an olefinic plastic with an unsaturated epoxy monomer or an unsaturated hydroxy monomer in the presence of an organic peroxide. The peroxide-crosslinking olefin copolymer rubber is for example, ethylene/propylene rubber, ethylene/propylene/diene rubber and the olefinic plastic is for example polyethylene or polypropylene. The resulting partially crosslinked thermoplastic elastomer has improved heat-bondability to resins and to metals and may be used for producing molded articles.

Title: Retainer ring
Inventor: BARNES THOMAS C
IPC: F01D11/00
Filed: 1987-12-10
Granted: 1992-03-03
Abstract: RETAINER RING ABSTRACT OF THE DISCLOSURE A retainer ring clamps, for example, a turbine cooling plate to a rotatable turbine disc. The retainer ring has a wedge-shaped channel that engages annular flanges on the cooling plate and the disc.  The wedge-shaped channel converts radial forces on the ring to axial clamping forces which secure the cooling plate to the disc.  Special tooling is not required to assemble the retainer ring to the cooling plate and turbine disc, and preloading of the cooling plate against the disc is not necessary.  An angled or slanted gap in the ring eases assembly and disassembly of the retainer ring onto the annular flanges of the cooling plate and turbine disc and ensures that axial and radial movement of the retainer ring is required for disassembly of the ring from the flanges.

Abstract: STAIN AND SCRATCH RESISTANT RESILIENT SURFACE COVERINGS                   Abstract The present invention relates to surface coverings, and in particular to coverings which comprise treated polyurethane or other wear layers.  A coating comprising a urea aminoplast which is at least partially etherified with alkyl groups comprising 4 to 10 carbon atoms, a vinyl modifier resin, a polyol, and an acid catalyst is formed on a release surface and thermally cured.  A crosslinkable wear layer composition is then cast on the cured layer and crosslinked, and the composite is transferred to a support surface.  Surface coverings are produced which exhibit surprising resistance to common household stains, and also improved scratch resistance.

Title: High speed data-clock synchronization processor
Inventor: AVANEAS NAPOLEON G
IPC: F02D45/00
Filed: 1988-01-05
Granted: 1991-03-26
Abstract: ABSTRACT OF THE DISCLOSURE The present invention generates a data clock for data processing circuitry by developing an optimum locally generated clock signal which is selected with each received data message.  This is achieved by utilizing a local crystal clock which serves as an input to a multiple active parallel tap delay line.  A register has the various delay signals input to it and a window generator strobes the inputs to the register so as to process the strobed levels of the various delayed clock signals.  This is done to detect a level transition in any of the clock phases.  Gating circuitry then chooses an optimum clock phase which has undergone a transition in a desired direction during the time window when the various clock phases were strobed.  As a result of the present invention, utilized bandwidth may be increased and data distortion is minimized so that the number of stations connected to a data bus provided with the data clock of the invention may be increased substantially.

Abstract: A multi-user speech recognition system includes several speech recognisers which are shared between many user terminals.  When a user terminal is activated, one of the recognisers is assigned to deal with voiced instructions received via that user terminal.  This recogniser requests the respective "templates" from a memory device.  A controller handles requests from the recognisers on a first-come first-served basis, and prevents later requests from interrupting earlier ones.

Abstract: ABSTRACT OF THE DISCLOSURE          A method and belt composition for improving the performance and flatness of thin revolving flexible casting belts of continuous casting machines wherein at least one wall of the moving mold is provided by a thin flexible endless metallic casting belt having a permanent insulative coating with fluid-accessible porosity in this permanent coating. Contrary to prior methods and apparatus which have sought to protect the wide thin casting belts, the present method for improving belt flatness and performance involves providing a Helium-containing gaseous film between the metal and the front face of the casting belt which is coated with a permanent insulative porous coating. For significantly improved results, this gaseous film contains at least 8 per cent and preferably 15 per cent and optimally 20 per cent or more of Helium by volume and is non-reactive with the metal being cast, resulting in a controlled increase In the rate of heat transfer and for causing such heat transfer to become more nearly uniform and stabilized across the width of the flexible casting belt than in prior continuous casting machines of the same moving mold cross-sectional shape and size. The freezing rate advantageously becomes stabilized at a substantially higher and more uniform rate, the belt flatness becomes stabilized and the cast metallic product is thereby substantially improved both in metallurgy and surface appearance. Also, copper or copper alloy casting belts are used in certain embodiments for enhancing heat-transfer effects and belt flatness. During casting at a given speed, the freezing rate and exit temperature of the metal being continuously cast can be controlled by varying the helium percentage in the gaseous film itself. In twin-belt machines, relative heat-transfer rates into upper and lower belts are controlled by adjusting the relative helium percentages in their respective gas films.
