Abstract

863,626. Photo-electric exposure meters. KAMERA-UND KINOWERKE DRESDEN VEB. May 30, 1958 [Feb. 20, 1958] No. 17310/58. Addition to 835,778. Class 40(3) In an exposure meter comprising a photocell 19 and a spring-controlled moving coil galvanometer 11, 14, the pointer 21a when displaced from its central position engages a contact 23a or 24a to start an electric motor 27 which drives an exposure controlling member 1 to restore the pointer to its central position. In a modification, the motor controls a mask in front of the photo-cell.
