Abstract
1339224 A.C. logic circuit; oscillator LICENTIA PATENT - VERWALTUNGS GmbH 1 March 1972 [4 March 1971] 9603/72 Heading H3T In an A.C. logic system A.C. signals at an output terminal A are delayed with respect to A.C. input signals at E by a unijunction transistor timing circuit which operates after a period to trigger a blocking oscillator circuit into generating pulses. The pulses may be amplified by a transistor 6. The input A.C. signals are rectified and smoothed at the secondary of transformer 1 and provide power to the timing and blocking oscillator circuits. When capacitor 19 is sufficiently charged, unijunction transistor 20 conducts to discharge the capacitor through resistor 24 and trigger the blocking oscillator comprising transformer 4 and transistor 5.
