Abstract

459,302. Valve generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London, and BANKS, G. B., Highfields, First Avenue, Chelmsford. July 5, 1935, No. 19309. [Class 40 (v)] A saw-tooth-voltage generator comprises a condenser 3 from which the voltage is derived and which is continuously charged through a resistance 4 (preferably a saturated diode or a tetrode) and is shunted by the anode-cathode path of a back-coupled tetrode valve to the screen of which the synchronizing impulses are applied. A bias battery ensures that the valve is normally nonconducting, but when the condenser voltage reaches a sufficiently high value, or a synchronizing impulse is received and current does flow in the anode circuit, the back-coupling ensures that it will increase and so discharge the condenser rapidly.
