Patent CA-1280467-C (CA)
Inventor: TANAKA KANJI
IPC: H04B1/16
Filed: 1986-12-17
Granted: 1991-02-19
Abstract: ABSTRACT OF THE DISCLOSURE In an AM stereo receiving apparatus for decoding an AM stereo broadcasting signal of an ISB system, an envelope detecting circuit detects an output of an intermediate frequency amplifying circuit and a DC removing circuit removes a DC component therefrom, so that a stereo sum signal (L + R) is obtained.  A quadrature detecting circuit detects quadrature of the output of the intermediate frequency amplifying circuit.  A multiplying circuit multiplies the stereo sum signal (L + R), which is amplified a times as much by a first amplifying circuit, and the output of the quadrature detecting circuit.  An addition circuit adds the output of the quadrature detecting circuit, which is amplified b times as much by a second amplifying circuit,  and the output of the multiplying circuit.  The output of the addition circuit becomes  a  stereo difference  signal  (L  -  R)  by appropriately setting the amplification factor a of the first amplifying circuit and the amplification factor b of the second amplifying circuit.

Title: Process for producing laminated resin foam and mold therefor
Inventor: KITA TETSUO
IPC: B29C44/04
Filed: 1986-12-24
Granted: 1992-10-27
Abstract: ABSTRACT OF THE DISCLOSURE            An improved process for producing a laminated resin foam composed of two resin foam layers of different charac-teristic properties wherein the layers are integrally bonded together.  A first foamable resin liquid for forming flexible foam is poured into a first space in a foam processing mold on one side of a barrier projecting from the wall of the mold and pouring a second foamable resin liquid for forming a foam less flexible than the first flexible foam into a second space in said foam processing mold on the other side of said barrier.          The two foamable resin liquids foam beyond the barrier into contact with each other to form the two laminated foam layers.          One improvement in the process includes wetting a substantial portion of the mold cavity with the first foamable resin liquid.  Various shapes of molds and barriers will produce different  shapes and characteristics of the resultant foam pad, such as for a car seat.

Title: Satellite communications system employing frequency reuse
Inventor: ROSEN HAROLD A
IPC: H01Q25/00

Granted: 1990-12-18
Abstract: SATELLITE COMMUNICATIONS SYSTEM    EMPLOYING FREQUENCY REUSE                    ABSTRACT OF THE DISCLOSURE                   A satellite communications system employs separate subsystems for providing broadcast and point-to-point two-way communications using the same assigned frequency band. The broadcast end point-to-point subsystems employ an integrated satellite antenna system which uses a common reflector (12). The point-to-point subsystem achieves increased communication capacity through the reuse of the assigned frequency band over multiple, contiguous zones (32, 34, 36, 38) covering the area of the earth to be serviced. Small aperture terminals in the zones are serviced by a plurality of high gain downlink fan beams (29) steered in the east-west direction by frequency address. A special beam-forming network (98) provides in conjunction with an array antenna (20) the multiple zone frequency address function. The satellite (10) employs a filter interconnection matrix (90) for connecting earth terminals in different zones in a manner which permits multiple reuse of the entire band of assigned frequencies. A single pool of solid state transmitters allows rain disadvantaged users to be assigned higher than normal power at minimum cost. The intermodulation products of the transmitters are geographically dispersed.

Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus for the discharge of powder by a fluidic propellant is suitable for use as a fire extinguisher, the apparatus including a container wherein powder and propellant is pressurized prior  to  use  of  the apparatus.    Discharge of the powder and the propellant from the. container is accomplished by means of a diaphragm in a wall of the container, there being a gas generator contained within a well of the container for providing an overpressure which, in combination with the pressure to which the propellant has been charged, fractures the diaphragm,  Thereupon, the propellant and the powder exits the container in a homogeneous stream The overpressure is less than approximately 30 per cent, preferably 20 per cent of the  pressure to which the propellant and the powder are subjected during a charging of the container with the powder and the propellant.  The charge pressure is in the range of 400 - 600 p.s.i. so as to be many times greater than the pressure of an environment external to the container. A battery operated circuit may be connected between a fire sensor and the gas  generator for activation of the generator in a modular self-contained form of fire extinguisher.
