Abstract
441,558. Television. HALL, C. P., 64, Palmers Avenue, North Cheam, Surrey, and FLYNN, H., 56, Balcombe Street, Dorset Square, London. July 25, 1934, No. 21794. [Class 40 (iii)] Complementary vision and sound signals are recorded by two correspondingly modulated beams of light directed simultaneously on a moving light-sensitive film 12. The object 1 is scanned by a mirror drum 5 or an apertured disc, Fig. 2 (not shown). The object may be a kinema film, Figs. 3 and 5 (not shown), scanned by a cathode-ray tube, Fig. 4 (not shown). The recording-film is run first in a forward direction, shifted laterally, and run in the reverse direction to provide four recorded tracks, Fig. 6 (not shown). For reproduction, two light beams pass through the vision and sound records respectively and are incident on light-sensitive cells connected to a television receiver and a reproducer of sound, Fig. 7 (not shown).
