Abstract

953,359. Transistor oscillator circuits. PYE Ltd. Nov. 15, 1961 [Nov. 23, 1960], No. 40280/60. Heading H3T. The recurrence frequency of a saturable core transistor blocking oscillator is varied by altering the value of a direct current passing through a control winding on the core. As described, the core has three parallel limbs with primary winding P and secondary windings on the middle limb and control windings W1, W2 on the outer limbs, the current in the control limbs determining the point at which the core saturates. The control current may be varied by connecting the windings in series with a variable resistor R3 across the power supply. Alternatively the current may be varied automatically.
