Filed: 1965-03-17
Abstract: 1,048,418. Transistor switching circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 17, 1965 [March 18, 1964], No. 11232/65. Heading H3T. [Also in Division G4] In a switching circuit comprising a seriesconnected pair of transistors 31, 32 the breakdown voltage of the switch in its " open " condition is increased by the use of semiconductor devices such as 37, 38, 39 in series with the control signal. Fig. 1 shows a multiplexing system in which the outputs from transducers 10A . . . 10F are selectively switched by circuits 11A . . . 11F to an analogue-digital converter 13 under control of switching signals supplied to winding 33B of a transformer. It is shown that the breakdown voltage in the " off " condition is increased by diodes 37 or 39 and Zener diode 38. The latter may be replaced by a transistor (Fig. 2, not shown). The emitter/collector connections of transistors 31, 32 may be transposed so that the transistors operate in their normal mode.

Abstract: 1,043,472. Photographic cameras. COMPUR-WERK G.m.b.H. March 23, 1965 [April 10 1964], No. 12135/65. Heading G2A. The exposure period of the shutter of a photographic camera is controlled electrically by a pulse generator feeding a number of series connected frequency dividers whose outputs can be selectively connected to an amplifier controlling a solenoid in the path of the shutter operating mechanism. The frequency dividers can be flip-flops or pre-magnetized ring cores. The shutter is set by turning the blade ring 50 against the spring 52. Upon release by the lever 9, the shutter blades 46 are stopped in the open position by the core 36a of solenoid 36 engaging projection 50c on the ring. The shutter is held open for the preselected exposure until a pulse from the appropriate frequency divider operates solenoid 36 to release the shutter. A cam 50d engages a switch member 54 at the start of the shutter run down to make the electrical circuit operative. In an embodiment a camera for taking series pictures has a pivoted shutter blade controlled by two solenoids, one operated by a regular pulse and the other by a pulse from a frequency divider associated with the selected exposure time. In a further embodiment the camera shutter is electrically controlled to provide either series pictures or single pictures.
