Patent GB-2041678-A (GB)
Title: Phase locked loop control system
IPC: G01C19/06
Filed: 1979-02-08
Abstract: A phase-locked loop includes: a high frequency (e.g., 20 MHz) crystal controlled voltage controlled oscillator (VCXO); a divider (33b) for dividing the VCXO frequency down (e.g. by six decades); a phase comparator (35) for comparing the output of the divider with a low frequency reference signal; a loop filter (37) for filtering the output of the phase comparator so as to give the loop its desired dynamic response characteristic and bandwidth; and, a summing amplifier (39) for summing the output of the phase comparator with a modulation signal. The arrangement controls the frequency of the power applied to a gyroscope to rotate the seismic mass (wheel) of the gyro so as to compensate for movement of the gyro case about the spin axis of the gyro, the modulation signal having a voltage level linearly related to the rate of movement of the gyro case about its spin axis. This signal is obtained from a second gyro mounted so as to sense movement about the spin axis of the gyro whose power frequency is being modulated. <IMAGE>

Title: Flexible Self-sealing Wall Member
IPC: B32B7/04
Filed: 1979-02-13
Abstract: Layers 22 to 25 of natural or synthetic rubber are held together at spaced points by lines of drop thread stitching 28 or by spots of adhesive so that the sheets are free to move across each other between the points of connection. The wall may also include a reinforcing fabric web 21, and an outside barrier layer 20 and inside barrier layer 26, both layers being impermeable to fuel held in a tank of which the wall member may form a part. The wall member is self- sealing when penetrated by a projectile because the rubber layers then undergo large dynamic elongations but rapidly recover to close up the holes formed, these holes generally being out of alignment. <IMAGE>

Title: Flat Tube Heat Exchanger
IPC: F28D9/00
Filed: 1980-03-14
Abstract: A heat exchanger (Fig. 1) has nests (11, 11) of straight, flat tubes (21) with their broad sides adjacent and spaced apart to provide intermediate spaces. One medium, for example oil, flows through the tubes, and another medium, for example cooling air, flows in the intermediate spaces across the tubes. To provide a curved path (for instance an annular path) of flow of the one medium, yet using the straight, flat tubes, an angular connecting box (12) is used. Plates (23) with apertures (22) provide for connection of the nests of tubes to the angular connecting box. By the use of several such boxes and nests of tubes, an annular heat exchanger can be built up, with minimum waste of material during manufacture. <IMAGE>

Title: Body-implantable electromedical apparatus
IPC: A61N1/08
Filed: 1979-07-20
Abstract: A cardiac pacemaker includes a microprocessor 300 and a memory 302 capable of being programmed with a variety of processes for stimulating a heart and/of sensing and transmitting to an external device conditions of the heart or pacemaker. The microprocessor controls a multiplexer 306 to input signals from atrial and ventricular leads, the power source or a reed switch operable by an external magnet, on lines 338 a-f. The output comprises decoder 342 and latch 340 with output select switches 330 which are selectively operable to supply stimulation pulses to the leads or allow sensing. External apparatus 343 may transmit coded information to change the stored program or operation of the reed switch may select a different program starting address. The microprocessor 300 includes an address counter 307, and an auto reset oscillator circuit 344 periodically (e.g. every 0.5s) applies a reset signal to reset the address to the program starting address whereby if a noise signal (eg. from a defrillation pulse) causes an erroneous or meaningless memory location to be addressed the program will not 'hang up'. Reset circuit 344 is defeated during normal operation by a signal on line 346. <IMAGE>
