Abstract
372,348. Television. FERNSEH AKT.- GES., Goerz-Allee, Zehlendorf, Berlin. Feb. 2, 1931, No. 3333. Convention date, Feb. 5, 1930. [Class 40 (iii).] In television, a synchronizing signal of constant frequency and duration transmitted at the end of each line, is selected by suitable filters at the receiver, rectified, and supplied to a synchronous motor, e.g. a La Cour wheel. The La Cour wheel responds only to the line frequency and not to the frequency of each individual signal. The synchronizing signals may be produced by scanning a grating placed at one side of the object or by impressing an oscillation from a generator directly on the transmitter at the end of each line. At the receiver, the selecting circuits may damp the oscillations so that they just reach their maximum during their duration.
