Filed: 1974-07-26
Abstract: 1450849 Cameras FUJI PHOTO OPTICAL CO Ltd 26 July 1974 [28 July 1973] 33198/74 Heading G2A A light emitting indicator 6, for indicating in a camera view-finder the output of a photo-detector 1 exposed to object light, is energized by a square wave from an oscillator 8, the duty cycle of the square wave being controlled by a modulator 7 connected to the photo-detector 1, whereby the brightness of the indicator 6, as seen by the user, depends on the brightness of the object to be photographed. Thus for instance with a bright object the brightness of indicator 6 is increased so that it is distinguishable against the object in the camera view-finder. A prior art arrangement is described in which the brightness of the indicator is controlled by a second photo-detector. Preferably indicator 6 comprises numeral-shaped lightemitting diodes for indicating shutter speed. Other details are described in Specification 1450848.

Abstract: 788,998. Koepe pulley controls. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 28, 1955 [Nov. 18, 1954], No. 33458/54. Class 78 (5). A Koepe pulley in a mine hoist has the actuating member S1 of the protective control gear PG releasably coupled with the Koepe pulley KP, the position of the member being adjustable by means SM responsive to the position of the conveyance whereby the said member is automatically returned to its correct positional relationship with the mine cage, thus compensating for " creep " in the operating cable. As shown, Koepe pulley KP is driven by motor MW, the protective control gear (e.g. Lilly controller) PG being coupled to said motor through shaft S1, lost-motion drive LM, and gearing G. Insulating drum D is coupled to said protective gear PG, the drum carrying slip rings R1, R2, R3 co-operating with brushes B1, B2, B3 and forming part of the electric circuit. When the mine cage reaches its stopping position it actuates switch CS and if slip has occured, one of the slip rings R2, R3 engages one of the brushes B2, B3 and thus energizes one of the relay coils OCF, OCR. This in turn operates two relay switches, either F1, F2 or R1, R2. The armature and appropriate field winding of reversible motor SM is therefore energized and the thrustor T is also caused to disengage clutch C, so that the motor SM drives the protective control PG to reset the latter relative to the Koepe pulley to allow for the slippage of the cable which has occurred. Alternatively the drum D may be replaced by cams. Specification 757,623 is referred to.
