Patent GB-2013296-A (GB)
Title: Power-operated boosters
IPC: B60T13/14
Filed: 1979-01-24
Abstract: A pedal-operated brake booster incorporates a valve mechanism for controlling pressurisation of a boost chamber 52. The valve mechanism comprises a pedal-operated piston 5 and a pressure-responsive valve spool 19 which is coupled to the piston 5 for limited relative movement in a longitudinal direction within a working chamber 54 in the piston 5. The spool 19 is movable with the piston 5 (by ring 26 abutting shoulder 65) in an initial brake-applying direction in which the spool 19 is operative to isolate (at bores 35, 36) the boost chamber 52 from an exhaust port 38 and the piston 5 is operative (by its shoulder 15) to place an inlet port 12 in communication with the working chamber 54. This causes the spool 19 to move relatively away from the piston 5 in response to pressure fluid in the working chamber 54 which fluid is admitted (via passages 29, 66 and 33) to the boost chamber 52 hence providing a greater movement of a master cylinder piston 8 than of the piston 5 unless there is a pressure supply failure when the piston 5 actuates the piston 8 directly. The pistons 7 and 8 may be separate or integral. <IMAGE>

Patent GB-2064262-A (GB)
Title: Arrangement for controlling listening room reflections produced by loudspeaker systems
IPC: H04R1/26
Filed: 1979-10-24
Abstract: The employment of two or more separate, but closely adjacent speaker/systems, having within their separate frequency responses a common frequency range (or ranges), but with differing radiation patterns (and hence differing rates of attenuation with distance from the source) for the same frequencies within the range(s) considered allows "Far-Field" sound cancellation while at the same time leaving the "Near- Field" virtually unaffected in sound level. As the listener in a normal small domestic listening room lies within the "Near-Field" condition relative to the direct sound from the combined systems, but lies within the "Far-Field" condition relative to the reflected sound, the latter can be considerably reduced in volume level without significantly affecting the former.

Patent GB-2083300-A (GB)
Title: Electronic flash equipment
IPC: H05B41/32
Filed: 1980-06-27
Abstract: The unit comprises a charging control circuit which is a solid state switching circuit effective to delay the recharging of main flash tube capacitor or capacitors, after discharge through the flash tube A, to allow the flash tube to quench completely. When capacitors B discharge through the tube A, capacitor C discharges rendering transistor G conductive and transistor F nonconductive so that triac D cannot conduct in the negative phase of the AC cycle. The similar components C', G' and F' prevent triac D conducting in the positive phase of the cycle thus the main storage capacitors B are not recharged until the charge on C, C' is dissipated. The same solid state switching circuit can be used to stabilise the voltage on the flash tube capacitors B at any of a number of desired charge levels. The flash tube A can be mounted with a tungsten-halogen lamp 33 in a single housing. <IMAGE>
