Granted: 1991-01-15
Abstract: TITLE HEAT RESISTANT CHLOROPRENE COPOLYMERS      ABSTRACT OF THE DISCLOSURE Mercaptan, dialkyl xanthogen disulfide or sulfur modified chloroprene based copolymers are disclosed.  At least 92% of the chloroprene derived units present in the copolymer have a 1,4-trans configuration.  The copolymer comprises units derived from chloroprene, up to 20 parts and preferably 2 or more parts per 100 parts chloroprene derived units of units derived from 2,3-dichloro-1,3-butadiene, and 2 to 25 parts per 100 parts of chloroprene and 2,3-dichlorobutadiene of randomly distributed units derived from styrene;  -methyl styrene; acrylonitrile; methacrylonitrile; acrylic acid; methacrylic acid; maleic acid; fumaric acid; and lower alkyl acrylamides, methacrylamides, acrylates, methacrylates, maleates or fumarates.

Title: Flexible composite ultracentrifuge rotor
Inventor: BRESLICH FRANCIS N JR
IPC: B04B9/08
Filed: 1986-12-02
Granted: 1991-05-21
Abstract: TITLE        FLEXIBLE COMPOSITE ULTRACENTRIFUGE ROTOR                 ABSTRACT OF THE DISCLOSURE        An ultracentrifuge rotor is characterized by a  hub  having  radially  outwardly  extending  curved spokes.  The outer ends of the spokes are received in a groove defined on the inner peripheral surface of an annular rim.  Sample carriers are affixed to the rim at circumferentially spaced locations defined between adjacent pairs of spokes. As the rotor rotates the disparity in physical properties between the hub and the rim as well as the flattening of the curvature of the  spokes  causes the  hub to  grow to  an extent  at least equal to that of the growth of the rim.

Title: Method and structure for forming a reaction product
Inventor: KRIJGSMAN PIETER
IPC: C01B13/18
Filed: 1987-07-02
Granted: 1992-08-11
Abstract: METHOD AND STRUCTURE FOR FORMING           A REACTION PRODUCT Pieter Krijgeman ABSTRACT OF THE DISCLOSURE     A reaction product is formed by a process which involves the transfer of the reaction product from an autoclave to a receiving vessel at a substantially constant flow rate.  Just prior to this transfer, the pressure in the receiving vessel is brought up to the pressure in the autoclave by passing gas from the autoclave to the receiving vessel.  The flow of gas from the autoclave to the receiving vessel is then stopped, and the pressure in the receiving vessel is allowed to drop due to transfer of heat from the gas to the walls of the receiving vessel.  The resulting pressure difference between the autoclave and the receiving vessel is used to initiate the transfer of the reaction products from the autoclave to the receiving vessel.  A pressure release valve on the receiving vessel is then controlled by means a signal derived from a flow meter which measures the flow rate of the reaction products flowing from the autoclave to the receiving vessel to maintain constant this flow rate.

Abstract: PHN 11.853 ABSTRACT:          Data processing device composed of four data processing modules of substantially identical construction, with protection both against simultaneous single-bit failures in a plurality of data processing modules and against failure of a single data processing module.     A data processing device is composed of four data processing modules (100, 102, 104, 106) which include mutually corresponding processing means (12, 14, 16, 18) and storage modules (28, 30, 32, 34) which are connected thereto, which data processing system includes an interconnection network (82, 84, 86, 88) which is fed by the respective data processing modules in order to apply bytewise generated processing results from any data processing module to any other data processing module. Each data processing module comprises an input decoder (54, 56, 58, 60) for receiving such intercommunicated processing result and therefrom reconstructing a correct bytewise processing result from mutually incongruent processing results so received even in case of failure of one data processing module for feeding to the local processing processing means. Error protection codes are presented that guarantee the correct operation of the device even if one of the data processing modules fails in an arbitrary manner or, alternatively, up to three single bit errors occur in any particular 32-bit code word. If one data processing module is ignored as an erasure symbol, one bit error may be corrected in the partial 24-bit code word.

Inventor: RALSTON JOHN D
IPC: H01L21/263
Filed: 1987-10-06
Granted: 1990-12-04
Abstract: ABSTRACT          A multilayer semiconductor structure, formed of two or more separate layers of different materials can be selectively intermixed so as to become compositionally modified, such that the distinction between the different original materials is lost, at least partially.  This intermixing process employs irradiation with a pulsed or rapidly scanned laser or electron beam, generally at ambient conditions of temperature and pressure, at energy levels which avoid physical damage to the layered structure.  The intermixing may be more complete when multiple pulses from the laser or electron beam are employed.

Abstract: METHOD TO ACHIEVE A LINEAR STANDARD CURVE         IN A SANDWICH IMMUNOASSAY                         Abstract A method for obtaining an actual linear standard curve in a sandwich type of immunoassay where a first antibody bound to an insoluble support and a second unbound labelled antibody complex with the antigen contained in a test sample to form an insoluble antibody: antigen:labelled antibody complex which is then detected.  Unbound unlabelled first antibody and/or unbound unlabelled second antibody are added to the reaction mixture to divert excess antigen away from the desired end-product complex, thus rendering the antigen of interest the rate-limiting factor in the overall immunoreaction.  This results in a pseudo first-order reaction which produces an actual linear standard curve.

Patent CA-1330122-C (CA)

Granted: 1994-06-07
Abstract: ABSTRACT                         VIDEO CODER        A coder assembles bursts of blocks of  image data  (eg transform coded  coefficients)  and  associated overhead data into a sequence of data which are then transmitted.   Both the transform coded coefficients and the overhead data are initially stored in separate FIFO memory   stores.      The   blocks   of   transform   coded coefficients have a 'last coefficient' flag accompanying the  last  coefficient,  and  the  overhead  information contains  a  unique  word  SWITCH,   after  the  header information but  before  the  'end-of-block'  flag.    The 'last  coefficient'   flag  and  the  SWITCH  word  are recognized by  a  toggle  controller which  controls  the reading of the stores so that the coefficient data and overhead data are selectively passed to a buffer in a desired sequence.   The buffer is followed by a variable length coder which supplies the output of the coder at a constant bit rate.   Provision is made to calculate the quantity of output data represented at any time by the contents of the buffer and the result is used to control the rate of generation of image data.

Title: Automatic speech recognition using echo cancellation

Filed: 1988-11-25
Granted: 1994-01-11
Abstract: AUTOMATIC SPEECH RECOGNITION                USING ECHO CANCELLATION     Abstract A customer inquiry unit that allows the recognition of human speech in the presence of a initial prerecorded message transmitted by the customer inquiry unit via a telephone network.  The customer inquiry system is designed to be utilized to respond to inquiries received via the telephone network.  The system functions by responding to a telephone call received via the network to transmit an initial speech message to the customer.  Due to a variety of network problems, a portion of the speech energy of the message is reflected back to the inquiry system.  This reflected energy is commonly referred to as an echo.  If the customer starts to speak before the inquiry system has finished the initial message, the system utilizes an echo canceler to remove the echo received back from the telephone network and only transfers the speech response to a recognition subsystem.  The echo canceler adapts to the telephone network during the initial portion of the initial speech message before the customer can respond.
