Abstract
490,523. Television. STOLL, SIR O. Jan. 13, 1937, No. 1060. [Class 40 (iii)] An optical image is projected on a photoelectric surface 3 forming a mosaic of lightsensitive elements from which the resultant currents are taken by a commutator 5 and are mixed with currents from a microphone 9; at the receiver the sound and vision signals are separated by differentiation of carrier frequencies. The sound signals are led to a loud-speaker 14 and the vision signals by a commutator 12 to a bank of neon tubes which are activated successively. An associated reflector 14a projects the picture on a screen. Specifications 225,553 and 297,152, [both in Class 40 (iii)], are referred to.
