Abstract
386,183. Non-contact-making relays. AMERICAN TELEVISION LABORATORIES, Inc., 7160, Santa Monica Boulevard, Hollywood, California, U.S.A. April 14, 1932, No. 10732. Convention date, April 24, 1931. [Class 40 (iv).] In a combined picture and sound wireless transmission in which the received picture transmission is recorded before reproduction whereas the sound transmission is directly reproduced, a " delay circuit is provided between the receiver 75 and loud-speaker 73 to compensate for the time interval the record strip 11 occupies between a recording block 14 and projector 52. The necessary delay action is provided by a coiled wire 80 of a calculated length interposed between the armatures 79, 81 of two relays 78, 82, the vibratory motion imparted to the armature 79 by the incoming sound signals being communicated mechanically to the armature 81.
