Abstract

351,178. Reproducing recorded sound. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and PETERS, W. H., of General Electric Co., Wembley, Middlesex. May 8, 1930, No. 14167. [Class 40 (ii).] Optical apparatus.- In reproducing sound from optical records a plurality of light-sensitive cells are simultaneously influenced by one beam, or by several beams passing through the same part of the record so that reproduction is not arrested by a breakdown of one of the cells. In one arrangement, a beam directed through a film record falls on an inclined glass plate or on inclined mirrors whereby a part of the beam is directed on to one cell and part on to another. In another arrangement, separate beams 12, as in the Figure, inclined to one another are directed through the same part 15 of the sound record 16 on to different cells 18, the beams emanating from separate light sources 13 or from a single source.
