Abstract
462,782. Television. COMP A G N I E POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. March 20, 1936, No. 8432. Convention date, March 29, 1935. [Class 40 (iii)] In a television transmitter for kinema films employing a cathode-ray tube and fluorescent screen, the scanning is effected in lines, e.g. horizontal, at right-angles to the direction of travel of the film, which is advanced uniformly, while the cathode-ray has imparted to it a component velocity at right-angles to the scanning lines, e.g. vertical, equal to and in the opposite direction to the movement of the film. In this way each image after the first is analyzed twice in succession, but the horizontal scanning velocity is made double that usually employed, so that each image is framed twice, instead of once, as normally, in <1>/25 sec., the ultimate effect being that use is made of the whole fluorescent screen, while at the same time the film is advanced at the normal rate of 25 images per sec.
