Granted: 1994-10-04
Abstract: A film bonding apparatus in which a film cut to a length corresponding to that of a base plate is bonded to the surface of the plate by the application of heat and pressure with a bonding roller.  The film is provided from a continuous roll and is cut to appropriate size, the trailing edge of the film being held tightly to avoid film wrinkling or air bubbles by the suction action of an edge holding member whose effective length is not less than the maximum width of the films to be bonded by the apparatus.  The holding member is moveable, at a speed equal to or slightly less than the rotative circumferential velocity of the pressure  roller,  the  speed  being  automatically adjusted to maintain appropriate tension on the film.          Coordinated movement between the film holding member and  the  pressure  roller  is  provided  by  a  gear mechanism.

Title: Power feed circuit for digital communications terminal equipment
Inventor: BULAN SERGIU
IPC: H04Q11/04
Filed: 1990-10-03
Granted: 1994-08-23
Abstract: Integrated Services Digital Network (ISDN) terminal equipments (TEs) are remotely powered from a central source via line interface circuits.  One function of the line  interface circuit is that of conducting energizing direct current for the associated telecommunications terminal equipment while providing effective over current protection in spite of widely variable load current requirements which occasionally may mimic a faulty over current condition.  The line interface circuit includes first and second power terminals for connection to a source of power, first and second line terminals for supplying said energizing direct current, and a current control means, being connected between a one of the first and second power terminals and a respective one of the first and second line terminals, for temporarily switching OFF an inrush current in excess of a dynamic limit, and permanently switching OFF a load current in excess of a static limit until a virtual open circuit condition occurs across the first and second line terminals.

Granted: 1995-05-16
Abstract: A flexible, laminated material for reforming into packages for contents of the type such as oxygen-and flavour-sensitive liquid foods, for example fruit juices.     The material displays a carrier layer of paper or paper-board and a preferably extruded layer applied to one face of the carrier layer (corresponding to the inside of the finished package), this layer consisting of a mixture of polyethylene and ethylene vinyl alcohol copolymer.     Since the barrier layer thus includes both a polar (the ethylene vinyl alcohol copolymer) and a non-polar (polyethylene) component, the material possesses barrier properties against both polar and non-polar flavour components, at the same time as the material moreover displays tightness properties vis-à-vis oxygen.

Title: Variable rate encoding and communicating apparatus
Inventor: YOSHIKAWA HIDETAKA
IPC: H04B1/66
Filed: 1990-12-20
Granted: 1995-12-12
Abstract: In a transmitter in the present invention, an input signal is input to a QMF (QUADRATURE MIRROR FILTER) bank 102 where the input signal is divided to a plurality of frequency bands to form corresponding band signals.  A distributed bit calculating unit 109 calculates respective bit rates with which the corresponding band signals are encoded on the respective power values of the band signals.  Quantizers 104-1, 104-2, ..., 104-n encode the respective band signals at the corresponding bit rates and input the resulting correspond-ing band codes to a cellulating unit 111 which incorporates the respective band codes into a cell as an information unit and sends the cell.  In a receiver, a cell is decomposed to obtain the respective band codes, which are then dequantized to form the corresponding band signals. These band signals are synthesized to form a signal for the entire band, and the signal for the entire band is output as a decoded sig-nal.
Patent CA-2032909-C (CA)
Title: Csk communication system
Inventor: ENDO KAORU
IPC: H04B1/707
Filed: 1990-12-21
Granted: 1995-10-10
Abstract: The present invention provides new arrangements for various components of a CSK communication system:  modulator, correlators, demodulator, carrier detection circuit, and synchronization control circuit.  The various improvements provide more accurate demodulation of data from the received signal in the presence of noise and signal deterioration.  A modulator configuration permits the CSK system to use two M series codes in which the second code is simply a phase shifted version of the first code.  The PN correlators, via shift-registers, efficiently output two correlation signals.  The demodulator accepts two correlation signals from the correlators, detects auto-correlation peaks in the correlation signals, and uses the peaks to accurately determine whether the received bit has a value of "1" or "0".  The carrier detecting circuit detects the presence of data in the received signal.  A carrier detecting circuit conveniently allows demodulation of data without exact synchronization of the center of demodulator's monitoring window to auto-correlation peaks.  The synchronization control circuit generates accurate timing pulses that mark the start and end of each data bit.  If auto-correlation peaks appear consistently in one location for the duration of N consecutive data bits, subsequent timing pulses are delayed in accordance with weighted averages of the stored locations of auto-correlation peaks.  In one embodiment, separate correlation signal monitoring windows for demodulation and synchronization tracking may be set independently of each other, enabling the demodulator to clearly distinguish between an actual auto-correlation peaks and an inter-correlation peak, and the synchronization control circuit to attain stability by "averaging" out temporal effects of noise.

Title: Logical mapping of data objects using data spaces
Inventor: FECTEAU JEAN GILLES
IPC: G06F12/109
Filed: 1991-11-12
Granted: 2000-05-23
Abstract: Method and means are provided for simulating a contiguous data space within a computer memory, and for placing and accessing data objects of various sizes within the simulated contiguous data space. Multiple, sub-data spaces are concatenated in such a way that each page and each sub-data space in the contiguous data space are uniquely identified. Data objects are placed in the contiguous data space and at the first reference to a page of the data object, only the segment containing the referenced page in the contiguous data space is mapped to the database storage disk. Once a data space page is mapped, the operating system can read the page into memory without requesting a disk operation from the database manager. On modifying a page, if the database disk page location is changed, the contiguous data space page is re-mapped without changing the page address in the data space. Also, modified data pages are re-written to the database storage disk in an ongoing manner set by the user, instead of at intervals set by the operating system.

Granted: 2000-08-01
Abstract: The production which is customary in practice of monoazo compounds based on dichloro- and trichloroanilines or disazo compounds of the chlorinated biphenyl series by conventional coupling methods meets with difficulties in that the resulting pigments are contaminated by traces of polychlorinated biphenyls.      According to the invention, it has now been found that by addition of water-soluble olefins of the type (see above formula) (R=H, C1-C4-alk or C1-C4-Oalk; X = -COOR1, -CONHR2,or -NR3COR4, wherein R1 is hydrogen or optionally substituted C1-C4-alkyl, R2 is hydrogen or optionally substituted C1-C4-alkyl, R3 is hydrogen or C1-C4-alkyl and R4 is C1-C4-alkyl) in the azo coupling, the side reactions which form PCBs can be decidedly suppressed during synthesis of the pigments.
