Abstract: DETECTION LOGIC AND SIGNAL PROCESSING METHOD AND APPARATUS FOR THEFT DETECTION SYSTEMS                     ABSTRACT Improvements in theft-detection or surveillance systems of the type in which an alternating electromagnetic field is established across a doorway or other portal and is monitored to detect the presence within the field of a marker or tag member comprising a small strip of permalloy or like material of high permeability hidden or otherwise carried on merchandise or other articles and objects to thereby "mark" such merchandise or objects, i.e., to make them readily detectable even though hidden from view.  The improvements reside in signal-processing electronic circuity which increases detection sensitivity and accuracy while at the same time reducing erroneous detection results.  In par-ticular, the circuitry utilizes summing and differencing techniques to improve signal-to-noise ratios and eliminate previously-unsuspected sources of error, and additionally utilizes the concept of frequency spectrum-content ratios as a determinant in distinguishing between apparent detection of true markers from other objects or structures whose response to the alternating interrogation field closely resembles that of the true markers and would normally produce erroneous detection indications.  In doing so, detection signals are processed by use of sampling techniques representative of both marker-presence and marker-absence, comparison of these samples through summing, differencing and peak-integrating techniques, as well as other more particular approaches for reducing or eliminating the effects of error and/or noise signals resulting from or introduced by causes not previously understood or appreciated.

Abstract: HIGH PURITY SILANE AND SILICON PRODUCTION            Abstract of the Disclosure Silicon tetrachloride, hydrogen and metallurgical sillcon are reacted at about 400-600°C and t pressures excess of 100 psi, and specifically from about 300 up to about 600 psi to form di- and trichlorosilane  that is subjected to disproportionation in the presence of an anion exchange resin to form high purity silane. By-product and unreacted materials are recycled, with metallurgical silicon and hydrogen being essentially the only consumed feed materials. The silane product may be further purified, as by means of activated carbon or cryogenic distillation, and decomposed in a fluid bed or free space reactor to form high purity polycrystalline silicon and by-product hydrogen which can be recycled for further use.  The process results in simplified waste disposal operations and enhances the overall conversion of metallurgical grade silicon to silane and high purity silicon for solar cell and semiconductor silicon applications.

Abstract: Abstract:                METHOD OF ASSEMBLING AN ACTUATING            LEVER TO A POTENTIOMETER      A method of assembling an actuating lever (10) to a potentiometer (12) for use in electronic engine control systems for  internal combustion engines as a throttle position sensor to generate electrical signals indicating the angular position (A°) of the throttle blade.  In such systems, there is usually one known or "home" position from  which  the  position  of  the  throttle  blade  is determined in order to determine the injection demands of the engine.  The method herein is for accurately locating an actuating lever (10) to the moveable contact of the potentiometer (12) so that at the home position, signal generated by the potentiometer is a known valve.   In addition, the potentiometer only needs to be adjusted on the throttle body once it is assembled thereto to account for  throttle  body  tolerances,  thereby  satisfing  rigid engine control requirements which require the positioning of the potentiometer to be accurately known.

Abstract: HIGH CURRENT LOW VOLTAGE HEATING METHOD AND APPARATUS FOR   PRODUCING A SMOOTH FINISH SURFACE ON INJECTION MOLDED FOAMED   RESIN PRODUCTS          ABSTRACT OF THE INVENTION    The invention comprises a method and apparatus to quickly heat a mold cavity surface or portions thereof just prior to the injection of a foamable plastic resin.  The apparatus comprises one or more thin metal surface sheets or bands of high electrical resistivity in the mold cavity covering those portions of the mold where a smooth surface finish on the product is desired.  In an alternative form the surface sheets may be plated or sprayed metal of high resistivity on a layer of thin electrically non-conducting plastic in turn adhered to the mold cavity surface.    The thin metal surface sheet is resistance heated approximately 300°F in a few seconds or less by a low voltage high current source of electric power just prior to the injection of the foamable plastic.          The high current passing through the metal of high resistivity causes conversion of electrical energy into sensible heat very quickly to accomplish quick heating of the mold cavity surface sheet.  The low voltage eliminates the need for substantial electrical insulation between the thin metal surface sheet and the bulk metal of the mold.  Where steel molds and steel surface sheets are employed, the normal oxide coating on the steel serves as the insulation at the interface of the surface sheet and the mold.    To reduce or minimize arcing in the electrical switch gear employed to momentarily connect the high current low voltage source to the surface sheet, a water cooled electric heating pipe bypass is employed as an electrical energy sink during the portion of the molding process that does not employ heating of the surface sheet.

Abstract: AUTOMATED CATALYST REGENERATION IN A REACTOR          ABSTRACT OF THE DISCLOSURE            A technique, including an apparatus, for automatically regenerating a catalyst used in a process for obtaining a product in an exit stream from a raw material in a feed stream of a reactor, comprises determining the concentration of raw material in the feed and exit stream and obtaining a value for the catalyst selectivity as a function of the difference between the concentrations.  When a selected selectivity is reached, which is indicative of the need for the catalyst to be regenerated, regenerator equipment if activated for regenerating the catalyst in the reactor.  To continue the process, the feed stream is transferred to an auxiliary reactor during regeneration of the primary reactor, which contains regenerated or fresh catalyst.  When used in reactors for the hydrogenation of acetylene to ethylene, the concent-ration of hydrogen in the feed stream is also calculated with the selectivity equaling the concentration of hydrogen divided by the difference in concentrations for the acetylene in the feed and exit streams respectively.

Abstract: ABSTRACT OF THE DISCLOSURE     Strict care must be taken in the mass production of high packing density, disc-shaped information carriers such as repre-sented, for example, by the manufacture of compact discs, that no mix-ups occur of workpieces having different informational content during the production sequence.  Proceeding on the basis that disc magazines are employed for conveying the disc-shaped workpieces from one work station to the next, it is proposed that the disc magazines have a processing sequence for the workpiece stack they contain which is rigidly defined for all work stations by means of fitting parts.  Also, each workpiece stack and thus each disc magazine accepting a workpiece stack therein is accompanied by an identifier disc whose shape corresponds to the shape of a workpiece.  The identifier disc thus assumes the initial position in the rigidly defined hierarchy of a workpiece stack within a disc magazine.  This identifier disc is read first at an input side of a work station by means of a read unit before the working-off of the workpiece stack contained in the disc magazine is undertaken in the prescribed sequence.

Abstract: ABSTRACT OF THE DISCLOSURE     A vehicle wheel on which can be mounted a pneumatic tire which essentially comprises rubber or rubber-like synthetic material, and has a carcass with load-carrying cords which are anchored in the bead regions of the tire by means of inextensible core rings.  The wheel has a rigid rim with laterally outwardly disposed rim flanges; disposed axially in-wardly of these rim flanges on the radially outer side of the rim are seating surfaces for the tire.  To minimize disrupting effects on the tire tread, while at the same time improving the emergency operating conditions, a support member is disposed axially inwardly of the seating surfaces on the rim.  This support member has a diameter which is greater than the diameter formed by the rim flanges.  In the region of a given rim flange, the tire wall extends laterally outwardly from a given core ring in a substantially flat manner, and in particular in an angular range of from 0° to 20° relative to the axis of rotation of the tire.  The carcass neutral line passes through the same region of a given rim flange in such a way as to avoid a turning point.  The core rings are eccentrically disposed in their bead regions in such a way that when the tire is mounted, the inner diameter of the tire in these bead regions is less than it is during mounting of the tire.
