Abstract

267,120. Holweck, F. March 3, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Copying-telegraphs; television. - At each of several receiving stations a cathode ray or other oscillograph is arranged to explore a phosphorescent surface or screen in synchronism due to the action of different frequencies either of the same carrier wave or of two carrier waves of different frequencies emitted by a control station, and at a transmitting station, which may or may not be the control station, a similar svnchonized oscillograph explores the picture to be transmitted in conjunction with a photo-electric cell to transmit a wave modulated in accordance with the light intensities of the successive picture areas. The " picture may be a stationary document or a moving kinematograph film, and the images on the receiving screens may be recorded photographically.
