Patent GB-2141186-A (GB)
Title: Manually actuated pump having pliant piston
Inventor: CORSETTE DOUGLAS FRANK
IPC: B05B11/00
Filed: 1984-06-05
Abstract: A dispensing pump of the pressure accumulating type includes an assembly (10) of a pump body (12) and a separate piston member (16) with a lip seal (23), the body including a closure cap (12) for securing the assembly in fluid tight communication with the opening of a container of flowable product to be dispensed, a plunger/accumulator (25) forming a variable volume pump chamber (26) together with the piston and being reciprocable relative thereto, and a plunger head surrounding the plunger. The plunger has a vent seal (48) for opening and closing a vent chamber (49) defined around the piston. The closure cap is of a hard and durable material, while the separate piston is softer and more compliant which gives its lip seal (23) good definition which avoids pump chamber leakage as it precisely conforms to the inner diameter of the plunger and to any irregularities thereof. Likewise, the plunger head is of a rigid and durable material, while the plunger is softer and more compliant so that its vent seal (48) will better conform to the vent chamber wall, which it slidingly engages, to avoid leakage of product through the closed vent chamber. The piston has an inlet valve (21) thereon which may be of a wide variety of types. <IMAGE>

Title: Explosive devices
Inventor: HEWITT ROBERT ARNOLD
IPC: F42B1/02
Filed: 1984-06-28
Abstract: An explosive device comprises two axially symmetric liners 2 and 3 between which a single main charge 4 is disposed. The liners 2 and 3, each of which can form a penetrative jet, each have an crenelated periphery and a respective explosive layer 7 and 8, disposed on the side of the liner remote from the main charge, extends into the crenelations. One or other of the explosive layers is detonated by a detonator 9 or 10 and each produces for the main charge a respective detonation pattern which causes the formation of the opposite liner into a penetrative jet. <IMAGE>

Title: Missile control systems
Inventor: DAROGA NADER DADABHOY
IPC: F41G7/34
Filed: 1984-09-10
Abstract: A military offensive or defensive missile control system comprises drones or pilotted aircraft transmitting photographs of the battle zone to a receiving station (15, 16, 17, 20) where the photographs are suitably coded, identified and stored. A transfer mechanism (21) transfers a target image to each of a number of cruise missiles in launchers (22) mounted on a transporter (24). The missile when launched follows a set trajectory based on flight data recorded in its auto-pilot. The target image is suitably processed during flight to generate images of the target in various lanes and differing angles of approach. On nearing the target area, the photograph received by the missile's optical system is processed likewise by a master computer which also matches the two sets of images so as to lock the missile on to the target. The control system is housed underground beneath a reinforced concrete bunker roof (11). <IMAGE>

Title: Receiver circuit with a temperature compensated demodulating stage
Inventor: RYDEL CHARLES
IPC: G06K7/00
Filed: 1991-04-05
Abstract: The receiving circuit for a pulsed amplitude modulated carrier, eg bi-phase NRZ signal, comprises, in succession: a bop antenna (L0) tuned to the carrier frequency by a capacitor (C3); a demodulating stage (T1, R1, R4, R3, R5) connected directly to the antenna and having a bi-polar transistor (T1), and a semiconductor temperature compensating means T3 thermally insulated from the bi-polar transistor, a voltage amplifying stage (T6, R36, R34, R10, R9); and a re-shaping stage (S1) for the output signals from the amplifying stage. The non-linearity of the base-emitter junction of the demodulating transistor (T1) generates by distortion a signal at the frequency of the modulating signal, and its limited pass band eliminates the carrier frequency. The receiving circuit may be contained in a battery operated self-contained device, for example a motor vehicle driver's personal module, in the form of a credit card for remote operation of the doors or other components of a vehicle.
