Abstract
476,777. Optical sound-reproducing apparatus. ZEISS IKON AKT.-GES. Oct. 15, 1936, Nos. 28056 and 28057. Convention dates, Oct. 22, 1935 and Nov. 6, 1935. [Class 40 (ii)] [Also in Group XL] An optical sound-film reproducing-apparatus is provided with a photoelectric cell 30 having an envelope of horse-shoe shape so as partly to embrace the hub of the drum 3, the cell being secured by its contacts 33, 34 to terminals 35, 36 separated by insulation 37 and mounted with insulation on a carrier 38 secured to the housing 1. A metal strip 39 provided with a light-beam aperture 41 is secured round the cell and electrical connections by a screw 40.
