Patent GB-2069104-A (GB)
Title: Solenoid valve
IPC: F16K31/06
Filed: 1981-02-02
Abstract: A three-way solenoid operated valve has a coil 10, a core 12 and an axially movable armature 18. One end of the armature engages a stem 52 which passes through the core and actuates a venting valve mechanism 48, 56. The other end of the armature actuates a main valve mechanism 26, 32. The armature is normally biassed by a spring 54 to close the main valve mechanism 26, 32. In this position a chamber 28 on the outlet side of the main valve is vented to an outlet 66 via passageways 36, 38, 40, 42 and 44. When the solenoid coil 10 is actuated the armature 18 opens the valve mechanism 26, 32 and closes the valve mechanism 48, 56. Fluid may then flow from an inlet 34 through the valve orifice 32 and through passageways 84, 74, 72 and 76 to outlet 30. <IMAGE>

Patent GB-2075694-A (GB)
Title: Method of measuring root-mean-square value of voltage
IPC: G01R19/02
Filed: 1979-10-30
Abstract: A method of measuring the root-mean-square value of voltage consists in converting the measured voltage into a heat flow, converting a reference voltage into a cooling flow, adjusting the reference voltage so that the heat flow resulting from the measured voltage is compensated by way of its absorption in the cooling flow resulting from the reference voltage, under the conditions of thermal insulation from the influence of the environmental medium, and in determining the root-mean-square value of the measured voltage on the value of the reference voltage.

Patent GB-2084359-A (GB)
Title: Apparatus and Methods for Controlling Three Phase Induction Motors
IPC: H02P23/00
Filed: 1981-09-25
Abstract: When a three phase induction motor is connected by three wires only, and its power factor is controlled by triggering triacs or other thyristor arrangements in response to deviation from a required value, a triac may cease to conduct prematurely because no other triac is conducting. Also the phase lag monitoring for control purposes may be incorrect through premature triac turn-off. If a triac 50 for one phase receives a trigger signal from a generator 16 and at the same time another triac 51 or 52, depending on direction of motor rotation, also receives a trigger signal from one of gates 75 and 76, the effect of premature turn-off is overcome by a further firing. Gates 84 and 85 are used to suppress erroneous phase-lag monitor signals from the comparator 21 when current in another phase, selected according to direction of motor rotation, has ceased. Other phases have similar arrangements. <IMAGE>

Title: Hand weapon with firing hammer and firing pin
Inventor: RALL DIETER
IPC: F41A3/72
Filed: 1983-05-06
Abstract: A hand weapon, particularly a self-loading hand weapon, such as a rifle has a firing hammer (66) acted on by a firing spring (67) and a firing pin (21) which is thrown by the hammer against the detonating compound of a cartridge, particularly a caseless cartridge, which is disposed in a cartridge chamber of the weapon.
