Abstract

1,135,530. Ignition systems. FORD MOTOR CO. Ltd. Oct. 12, 1967 [Nov. 9, 1966], No.46574/67. Heading F1B. An ignition system comprises an electronic oscillator 40 switchable from an oscillating state to a quiescent state, the oscillator comprising a transistor 44 having an input circuit and an output circuit, a feedback means providing a feedback path from the output circuit to the input circuit and comprising a magnetic circuit with a transformer having a gap 43 therein and timed means rotated by the engine for interrupting the feedback path in timed relationship to the engine, to switch the oscillator to a quiescent state and comprising a rotating vane 68 of diamagnetic material with cut out portions 74 rotatable through the gap in the transformer so as to interrupt the magnetic circuit. In a modification (not shown) an amplifier circuit couples the oscillator to the coil primary winding.
