Abstract

863,601. Photo-electric exposure control. GOSSEN & CO. G.m.b.H., P. Nov. 23, 1959 [Aug. 20, 1959], No. 39699/59. Class 40(3) Diaphragm blades forming a camera aperture are given identical motion by a single photoelectrically controlled pin. Pin 8 attached by arm 7 to a moving coil 4 receiving current from a photo-electric device, enters overlapping slots 18, 19, in diaphragm blades 9, 10 which are pivoted on bridge 13 and control the aperture of optical system 17.
