Title: Method and system for enhanced data transmission in a cellular telephone system
Inventor: ROBERT V JENNESS
IPC: H04M7/00
Filed: 1992-11-26
Granted: 1993-11-11
Abstract: A method and system are disclosed for enhanced data transmission within a cellular telephone system having multiple assigned voice channels separated by adjacent buffer voice channels. A data processing terminal is utilized to divide the data stream into multiple relatively short data packets which are then sequentially transmitted within alternate adjacent buffer voice channels. By switching from one adjacent buffer voice channel to a subsequent adjacent buffer voice channel, in a predetermined and repetitive order, as each data packet is transmitted, the amount of interference experienced in any one assigned voice channel is minimized. Synchronization between adjacent data packets may be achieved by either utilizing adjacent buffer voice channels in a predetermined and repetitive order or by concatenating an indication of the next buffer voice channel utilized with each data packet. A synchronization packet may also be included with each data packet to permit synchronization between adjacent data packets at the receiver.

Title: Reverse rotation prevention for scroll compressors
Inventor: Stephen l shoulders
IPC: F04C28/22
Filed: 1995-11-29
Granted: 1998-01-01
Abstract: A scroll compressor device (10) includes a pair of scrolls (12, 14) one of which being an orbiting scroll (12), a slider block (20) and a crankshaft (30). The orbiting scroll has a hub (12-2) with a bore which has an axis (B-B) and which receives the slider block. The crankshaft has an axis of rotation (A-A) and a drive pin (30-1) that is received in a bore (20-1) in the slider block. Either the pin or the slider block has a flat surface (20-2, 30-2) and is normally engaged by the other. The bore in the slider block is larger than the pin and generally coaxial with the bore in the hub. The drive pin acts through the slider block to drive the orbiting scroll during normal operation and the orbiting scroll tends to act through the slider block to drive the drive pin and crankshaft during reverse operation and pressure equalization through the compressor at shutdown. Reverse rotation prevention method comprises the following. The orbiting scroll and the slider block are movable with respect to the drive pin along the flat surface between a first position, in which the orbiting scroll engages the other one of the pair of scrolls during normal operation, and a second position in which the orbiting scroll is separated from the other one of the pair of scrolls upon slowing down and any tendency for reverse operation and pressure equalization. Centrifugal force produced solely by movement of the orbiting scroll and the slider block during normal operation tends to keep the orbiting scroll and the slider block in the first position. Device (36-() for causing the orbiting scroll and the slider block to move along the flat surface from the first position to the second position under conditions associated with slowing down and reverse operation whereby the pair of scrolls is separated, an unimpeded flow path is established through the compressor and reversing torque caused by gas loads is decreased by reduction of orbit radius.

Title: Rubber devulcanization process
Inventor: MYERS RONALD DAMIAN
IPC: C08J11/16
Filed: 1997-01-13
Granted: 2002-07-11
Abstract: A process for devulcanizing and functionalizing a rubber vulcanizate by desulfurization involves suspending a rubber vulcanizate crumb in a solvent which preferably swells the rubber vulcanizate before or during the devulcanization reaction and adding an alkali metal, such as sodium, to the suspension. The alkali metal cleaves mono-, di- and polysulfidic cross-linkages in the rubber vulcanizate to liberate rubber polymer having a molecular weight substantially equal to that of the rubber polymer prior to vulcanization. Functional groups derived from the solvent molecules bond to the devulcanized rubber's polymeric backbone. In addition to the functionalized devulcanized rubber polymer, carbon black may also be recovered for re-use in accordance with the process of the present invention. The functionalized devulcanized rubber may be subjected to a re-vulcanization reaction without separation of rubber polymer from the solvent by addition of an appropriate curing mixture.

Title: Multiple exposure masking system for forming multi-level resist profiles
Inventor: ULRICH BRUCE DALE
IPC: H01L21/027
Filed: 1997-06-06
Granted: 2000-06-11
Abstract: A method is provided for forming multi-level profiles from a photoresist mask.  The method includes exposing selected areas of a photoresist layer to two or more different patterns of light at different light dosage levels. For example, one pattern will be exposed to a relatively low dose of light, or to light for a short duration, and a second pattern will be exposed to a relatively high dose of light, or for a greater duration. The plurality of different exposures at different dosage levels occur prior to developing the photoresist. When the photoresist layer is developed, the pattern exposed to a lower dose of light will be etched substantially more slowly than the areas of the photoresist exposed to higher dose of light.  By controlling the development process to completely remove the resist in the areas exposed to a high dose of light and only partially remove the resist in the areas exposed to a lower dose of light, a multi-level photoresist profile is formed. Such a multi-level profile can then be used in subsequent semiconductor processing, for example, the formation of interconnects and vias.

Title: Method and equipment to correct error of a heterodyne interferometer
Inventor: RINN KLAUS
IPC: G01B9/02
Filed: 1997-07-17
Granted: 1999-06-11
Abstract: This invention describes a method to determinate the periodic error of a heterodyne interferometer. A repeated caliber-measure of a constant caliber-track that is divided into two track parts is carried out, where one part is, measured with said interferometer and the other part is measured with additional path-measuring system, which has no periodic error in the measure-track. Before each caliber-measure, each track part measured from said interferometer will be insignificantly changed. The 2nd track part is modified accordingly in the opposite direction. The sum of the track-change of a track part must at least correspond to an optical path-length-change in interferometer about the measure-light-wavelength. From the different caliber-measure result for the constant caliber-track, the periodic error part will be separated and a wavelength-dependent error curve can be plotted to correct any interferometer measurement.

Title: Apparatus for winding a thread onto a bobbin
Inventor: FAH THEO HOF
IPC: B65H54/28
Filed: 1997-12-08
Granted: 2000-02-11
Abstract: A bobbin winding machine has a winding advance device for winding a thread onto a bobbin having a thread guide which executes a traversing motion in a longitudinal direction of the bobbin. The thread guide is connected to a traversing element, which is operated by means of a motor-drivable driving wheel and guide pulleys. To compensate tension variations, the traversing element is conveyed via a preloading organ supported at right angles thereto. The guide pulleys are mounted in a fixed manner on a common carrier, and the preloading organ is formed by the driving wheel, which is supported on a tongue-like bracket carried by bending supports. By virtue of said arrangement, dynamic variations of the traversing element in the region of the points of reversal of motion are absorbed so that a very high traversing speed and a likewise very high positioning accuracy of the thread guide is achieved.
