Abstract

923,155. Photo-electric exposure control. KAMERA-UND KINOWERKE DRESDEN VEB. Aug. 21, 1961, No. 30228/61. Class 40 (3). [Also in Group XXXVI] The battery supplying the electric circuit of a camera is tested by depressing switch 2 so as to put the battery in circuit with resistance 3 and the exposure meter galvanometer 5 the pointer of which will engage contact 6 if the battery voltage is sufficiently high and allow energization of self-holding relay 7 so that the circuit including a photo-cell 12 and/or resistance 14 is then connected to the battery as well as the motor 17 operating the camera.
