Abstract: 628,126. Valve generating circuits. O'BRIEN, W. J. Aug. 26. 1946, No. 25490. Convention date, Aug. 27, 1945. [Class 40 (vi)] The frequency of an oscillator comprising a resonant circuit coupling the anode and control grid of a valve is rendered substantially independent of variations of space charge within the valve by means of a cathode resistor which is common to the input and output circuits and a capacitor which couples the cathode to the resonant circuit. In the figure the inductor 7 is tuned by capacitors 17, 18, 20, capacitor 20 having a negative temperature/capacity coefficient to compensate for the normal positive co-efficient of capacitors 17, 18. Negative feedback is provided in the circuit by the large un-byepassed cathode resistor 3, the R.F. voltage across which is fed back to both ends of the resonant coupling circuit by the split stator capacitor 24a which is adjusted until the oscillator frequency is rendered substantially independent of changes in the anode voltage of the valve. Inductor 7 is specially wound and impregnated as described in Specification 607,160, [Group XXXV], to minimise the effect of temperature changes upon its inductance and distributed capacity. In a modification, Fig. 2 (not shown), the control grid of the valve is coupled to the tuned anode circuit by a separate inductor and a capacitor coupling the cathode of the valve to either the control grid or anode circuits is adjusted to render the frequency of oscillation substantially independent of the anode voltage.
