Abstract
480,944. Television. PRIESS, W. H. June 25, 1936, No. 2594/38. Convention date, July 13, 1935. Divided out of 480,673. [Class 40 (iii)] Each of light sources G<2>, R<2> emits differently coloured light, which is modulated by signals from a corresponding photo-electric cell at a transmitter, and the rays are synthesized by a fixed prism p<2>as a single beam on a scanner M<2>, which forms an image in colour. The mirror M<2> is vibrated simultaneously in two directions at right-angles. The light sources are gas or vapour discharge lamps giving red and blue-green colours respectively. A diaphragm I<2> is interposed between the light source and the prism.
