Patent GB-2021683-A (GB)
Title: A two-speed pump assembly
IPC: F04B53/10
Filed: 1979-05-25
Abstract: A hand or foot operated hydraulic press tool has an actuating plunger 56 fast with a low pressure piston 82 and a high pressure piston 162 mounted concentrically within the piston 82. The plunger 56 is reciprocated, and the pistons operate in unison to draw liquid from a reservoir 80 through respective check valves 128 and 174 and deliver liquid under pressure to an output device through a conduit 88. As pressure increases the low pressure pump is effectively disabled by a pressure relief valve 90 and further liquid under pressure is then delivered by the high pressure pump working alone up to a limit set by a high pressure relief valve 112. When the required pressure has been achieved, relief is effected by operating a manual release valve 116. <IMAGE>

Patent GB-2029101-A (GB)
Title: Charge coupled device
IPC: H01L29/762
Filed: 1979-08-24
Abstract: The transport velocity and the transport efficiency in a charge coupled device are increased by applying the voltages to connections (6A, 6B, 6C, 6D) provided at regular distances along a continuous strip- shaped resistor (2) which is situated above the transport channel. Each of the CCD electrodes is formed by a part of the resistor (2) between two successive connections (e.g. 6A and 6B). Since a voltage drop occurs between the successive connections (6A, 6B, 6C, 6D) drift fields are generated in the semiconductor material below the intermediate strip-shaped resistors which form the CCD electrodes so that charge packets are transported more rapidly in the transport channel. The resistor (2) may be of low- doped substantially homogeneous polycrystalline silicon, and the connections (6A, 6B, 6C, 6D) may be highly doped polycrystalline silicon or aluminium. Two-, three- and four-phase CCD arrangements are described. <IMAGE>

Title: Tape recorder
IPC: G11B15/18
Filed: 1980-01-08
Abstract: A mechanism which links a magnetic head mounting chassis 20, 21 for movement with a playback mode selector 16 includes a spring 25 acting to bias the rear (right hand) end of the head chassis away from a main chassis 11 and the front (left hand) end of the head chassis towards chassis 11. The ends of the head chassis engage a T-shaped member 51 and a projection 71 both on chassis 11. Spring 25 also connects metal part 20 of the head chassis electrically to the metallic playback selector 16 so that members 20, 16 do not form a capacitor with the intermediate plastics chassis 11 which might interfere with recording. Heads 22, 23 (Fig. 3a) are mounted on a plastics part 21 of the head chassis, the part 21 including a elastic part 213 engaging under a member 111 on chassis 11 in the operative position, a part 551 to retract pinch roller arm 29 and prevent it coming off pivot 28, and a port 56 supporting a pinch roller bias spring 58. An autostop has a lever 24 (Fig. 11) pivoted on member 21 and movable by increased tape tension to swing a gear 76 into mesh with a gear 77 rotating with a capstan flywheel 44, whereby a projection 761 on gear 76 shifts a mode selector locking bar 38 to the release position. <IMAGE>
Patent GB-2068426-A (GB)
Title: Pinned component for textile machinery and method
IPC: D01G19/10
Filed: 1980-02-05
Abstract: A pinned component for use in textile finishing machines and other purposes has a plurality of pins projecting from the surface of its metallic body and the surface of the body is given a textured finish by means of a sandblasting or chemical etching process. The sandblasting or etching removes unwanted burrs or the like from the surface of the body and if the pins are secured in their apertures with adhesive will also remove excess adhesive, thereby allowing the component to operate more efficiently. A typical component which would incorporate the invention would be an opening roller for an open end spinning machine.
Patent GB-2042655-A (GB)
Title: Torque Limiting Clutch
IPC: F16D7/08
Filed: 1980-02-08
Abstract: A torque limiting clutch includes a driving member (9), a driven member (4), first biasing means (14) and second basing means (11), torque being transmitted from the driving member (9) to the driven member (4) through balls (10) located in slits in the driving member (9) and extending into recesses (24) in the driven member (4). When a predetermined torque is exceeded the balls (10) roll out of the recesses (24) causing momentary compression of the spring (14) and move to a non- torque transmitting position, (shown dotted), such movement causing an increase in the potential energy state of spring (11) which, once the speed of revolution of the driving member is reduced, causes the balls (10) to take up their torque transmitting position in recesses (24), the movement of the balls (10) into their torque transmitting position from their non- torque transmitting position not affecting the potential energy state even momentarily of the first biasing means (14). Thus the clutch can be automatically re-engaged merely by slowing down or stopping the drive shaft. A detent (18) may be provided to maintain the clutch in its disengaged condition. <IMAGE>

Title: Adaptive OCR front-end system
IPC: G06V30/10
Filed: 1980-04-09
Abstract: A light source 26 illuminates an information area on a document, the reflected light being detected by a sensor 38. A filter circuit equalizes the outputs of the sensor to produce an equalized video signal. The equalized video signal is then registered in a memory to represent the background signature of the information area. The registered background signature is then used as a reference for comparison with subsequent equalized video signals to produce corrected video signals, the registered background signal being updated as necessary in response to sensed white areas of the document. <IMAGE>

Patent GB-2070305-A (GB)
Title: Supervisory assembly including a television receiver
IPC: G08B13/00
Filed: 1981-02-19
Abstract: A supervisory assembly incorporates a sensing means operatively associated with a TV set, so that one of the options available to the user is that when the sensing means detects someone it responds by altering the TV output. For example it may blank the screen, cut the TV power supply, or use the TV to make an alarm noise. 
<??>The sensing means has a detecting device (1), the output of which passes through a signal processing circuit (2) so as to operate a switch element (4). The switch element can operate a TV control means (6), to affect the TV output. Other, conventional, alarms (5,7) may also be operated by the switch element (4). 
<??>The assembly has use as a burglar alarm, and also for warning that someone is closer to the TV than a safe watching distance. In the latter case it is useful if the assembly's response is delayed slightly, so as to prevent it from giving the alarm when e.g. someone changes TV channel. 
<??>The sensing means may operate by emitting a signal (eg. ultrasonic) and detecting any reflection of it.

Title: Process for the production of high-strength and high-modulus carbon fibers
Inventor: OYABU MIKIO
IPC: D01F9/155
Filed: 1982-08-27
Abstract: A process for the production of high-strength and high-modulus carbon fibers involves melting and spinning a mesophase pitch containing 1 to 40% by weight of a mesophase, rendering the resulting fiber infusible in air, carbonizing the resulting infusible fiber in an atmosphere of an inert gas, and optically graphitizing the carbonized fiber.
