Abstract

390,170. Light-sensitive cells. SCHNEIDER ET CIE, 42, Rue .d'Anjou, Paris. Sept. 29, 1931, No. 27067. Convention date, Nov. 27, 1930. [Class 40 (iii).] In a photo-electric device for use as a transmitter in electric signalling systems or a circuitclosing device in control systems, a. rotating pencil of light co-operates with an annular light-sensitive cell 12.
