Abstract
514,021. Television. KERBER, K. H. Aug. 27, 1938, No. 25228. Convention date, Sept. 11, 1937. [Classes 39 (i) and 40 (iii)] To obtain signals corresponding to the colours of successive elements of the picture, the brightness of those elements is kept constant by controlling the illumination with signals corresponding to the brightness. Signals corresponding to brightness and to colour are transmitted alternately by controlling the respective amplifiers VH, VF with square-topped oscillations from shaping valves 9. During the transmission of the brightness signals, these signals are also stored on the mosaic of a cathode-ray tube 13. During the next revolution of the scanning disc 1, the stored signals control a Kerr cell 12, or iris diaphragm or the source of light 15, Fig. 3 (not shown), to keep the intensity of each element of the picture 2 constant. The sensitivity of photo-electric cells 5, 6 increases or decreases lineally over the spectrum, and the signals therefore represent the colours of successive elements. According to a modification, a double electronic image dissector is used with two photo-electric plates, focusing systems and collectors.
