Abstract
643,347. Super - regenerative receivers. HAZELTINE CORPORATION. Aug. 25, 1947, No. 23466. Convention date, Sept. 24, 1946. [Classes 40 (v) and 40 (vi)] In a super-regenerative receiver having a separate quench oscillator a voltage developed from the quench oscillation supply dependent upon the amplitude of the quench oscillation is applied to the super-regenerative amplifier to offset variations in quench oscillation amplitude. As shown, the receiver comprises an amplifier valve 10 regeneratively connected to a tuned circuit 11, 12 coupled to the aerial and a detector valve 41 connected to the anode circuit of the valve. The quench voltage is generated by a separate oscillator valve 25 and applied through a capacitor 32. Part of the self-bias developed across grid resistor 29 is applied through resistor 35 to the grid of valve 10 to compensate for changes in the amplitude of the quench oscillation. In an alternative and more effective arrangement (Fig. 2, not shown), the compensating bias is obtained from a similar connection but the quench oscillation obtained from the grid is used as the anode supply for the super-regenerative amplifier. It is also suggested that the bias may be obtained by separately rectifying the quench oscillation.
