Abstract: 651,570. Generating high-frequency oscillations; pulsing carrier frequencies. BRITISH TABULATING MACHINE CO., Ltd. Dec. 20, 1949, No. 32620. Convention date, Dec. 29, 1948. [Class 40 (v)] A ringing oscillator comprises a resistor 16, rectifier 17, and resonant L.C. tank circuit 10, connected in series from a voltage supply line 15 to a voltage supply line 18 having a lower potential than the line 15, the rectifier offering its lower resistance to current flow from the line 15, whereby a steady current normally flows through the tank circuit. A double triode 20, which is normally biassed to cut-off, has its anodes connected together and to the junction of resistor 16 and rectifier 17, and its cathodes connected together and earthed, the control grids being connected through resistors 22 to a source of gate pulses. When a gate pulse is applied to the valve 20 it becomes conductive and the potential at point 21 is reduced, to interrupt the flow of current in the tank circuit and shock it into oscillation, removal of the gate pulse causing the tank circuit to be critically damped and the steady flow of current resumed. The load is connected at 14 and may be an acoustic delay line, the input capacitance of the load being represented by capacitor 12, and the rectifier 17 may be a germanium crystal diode.
