Abstract : The patent describes a low frequency astable blocking oscillator composed of a transistor with a first transformer winding in the collector circuit and a second transformer winding in the base circuit to provide regenerative feedback between the collector and the base. A capacitor is connected to the transistor and is charged by a constant current source to initiate operation of the blocking oscillator when a predetermined voltage is reached. A voltage breakdown device is coupled to the transistor to raise the voltage required by the capacitor before blocking oscillator action commences thereby providing low frequency operation.
