Abstract

475,189. Television. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. May 15, 1936, No. 13794. Convention date, May 15, 1935. [Class 40 (iii)] The framing signals consist of a first part a, which acts as a preparatory signal, followed by a second part b which forms the actuating signal. The line-synchronizing signals set up a voltage across a filter F, which prevents the signals affecting a gas-discharge valve II and leaks away during the gap a. The second part b is then able to overcome the bias Eg and trigger the valve II.
