Abstract

863,566. Photo-electric aperture control. KAMERA-UND KINOWERKE DRESDEN VEB. May 28, 1959 [Oct. 31, 1958], No. 18198/59. Class 40(3) [Also in Group XX] A photo-electrically controlled camera diaphragm comprises two diaphragm blades 6, 7, separately pivoted. The blade 6 is controlled by a pin wheel 10 mounted on the axis 9 of a moving coil measuring system energized by a photo-cell. The blade 7 is controlled by a pin 14 attached to the blade 6 which engages with slot 15 in the blade 7.
