Title: Method and apparatus for establishing spread spectrum communications
Inventor: DIXON ROBERT CLYDE
IPC: H04B7/26
Filed: 1991-10-03
Granted: 1998-12-01
Abstract: A method for establishing communications between a master unit (50) and a plurality of node units (51-55). Of the plurality of node units, K node units are assumed to have established communications with a master unit. A first (K+ 1) node unit of the plurality of node units desires to establish communications with the master unit. The method includes transmitting from the master unit a base-station spread spectrum signal (CSn1) having a common-signalling chip code, transmitting from the first node unit a second spread spectrum signal (CSm) with a first identification code using the common-signalling chip code, transmitting from the master unit a third spread spectrum signal (CSn2) with a master unit identification code, using the common-signalling chip code. The method further includes generating at the first node unit using the master unit identification signal (CSn2) a master unit chip code for transmitting spread spectrum signals (CNMK+1) to the master unit. Additionally, the method includes generating at the master unit using the first identification code, a first node unit chip code for transmitting spread spectrum signals (CMNk+1) to the first node unit.

Abstract: A movement actuator includes an elongate filament made of a flexible material, and a strip of shape memory alloy disposed on the surface of one side of the filament. The shape memory alloy is responsive to actuation signals, heat or electrical signals, for changing its shape and when its shape changes, it causes the filament to move, i.e., bend, to accommodate the change in shape of the alloy. Also included is a signal supply device for selectively applying heat signals or electrical current to the strip of shape memory alloy to cause the alloy to change its shape and cause the filament to bend. Other patterns for the shape memory alloy could be disposed on the filament to cause other kinds of movements. For example, a helical pattern of the shape memory alloy about the filament would cause the filament to twist when the helical pattern were caused to shorten or lengthen.

Title: Identification of a data stream transmitted as a sequence of packets
Inventor: WENDORF JAMES W
IPC: H04N21/236
Filed: 1994-01-25
Granted: 2005-05-03
Abstract: The contents of a digital data file, interspersed as packets of data in a bit stream containing entertainment signals and/or other data files, are quickly identified without a high system overhead for identification of each packet. The data file is divided into packets, and sequential groups of packets making up the file are identified as segments. The first packet of each segment has a prefix containing a service identification number, a block number, a segment number, and possibly segment length information, followed by data contents. The following packets of the segment have only the service identification number and block number, followed by the data contents. Where the file data are transmitted repeatedly, often without change in many segments, receiver processing time or power can be greatly reduced by including a version number or toggle bit in the segment prefix, so that a receiver can ignore the unchanged data.

Title: Method for preparing automobile shredder residue-synthetic plastic material composite
Inventor: LAZARECK JACK
IPC: B29B17/04
Filed: 1995-07-07
Granted: 1997-03-18
Abstract: A method is provided for processing a mixture raw automobile shredder residue, and virgin and/or contaminated synthetic plastic material, e.g., raw post consumer plastic waste. By means of this method, automobile shredder residue produced by a conventional automobile shredder is formed into a first stream by being ground in a first granulating zone to a reasonable small granular size using conventional equipment. A second stream comprising virgin and/or contaminated synthetic plastics material is ground in a second granulating zone. The two streams are combined to provide a processable mixture. The processable mixture is introduced into a high intensity mixer. The processable mixture is transformed into a semi-molten discharge stream by the kinetic energy imparted to the processable mixture by the mixer, while the mixer is substantially-simultaneously vented to remove and recover particulates therefrom. The particulates so recovered are recycled to an inlet which is upstream of the mixer. The semi-molten mixture emerging from the mixer is introduced into an extruder, or a press, where it is formed into a mass of the desired shape, and is cooled. This method allows for the production of useful, shaped masses from two different classes of materials which have been otherwise treated as waste.

Title: Process for preparation of taxane derivatives and .beta.-lactam intermediates therefor
Inventor: OJIMA IWAO
IPC: C07D205/08
Filed: 1994-01-28
Granted: 2005-06-28
Abstract: Taxol TM is a complex diterpene which is currently considered the most exciting lead in cancer chemotherapy.      Taxol possesses high cytotoxicity and strong antitumor activity against different cancers which have not been effectively treated by existing antitumor drugs. However, Taxol has a problem with solubility in aqueous media, which may impose some serious limitation in its use. Taxotere seems to have antitumor activity superior to Taxol with better bioavailability. Taxotere has a modified Taxol structure with a modified C-13 side chain. This fact strongly indicates that modification on the C-13 side chain would provide a new series of Taxol and Taxotere analogues which may have higher potency, better bioavailability and less unwanted toxicity. The present invention provides efficient and practical methods for the syntheses of Taxotere and its analogues of the formula: (see formula I) through .beta.-lactam intermediates of the formula: (see formula II) and their coupling with a metal alkoxide baccatin III derivative of formula: (see formula III)
