Abstract: 1,112,228. Oscillators. R. W. REICH. 9 Feb., 1967 [22 March, 1966], No. 6142/67. Heading H3T. [Also in Division G3] In a timepiece including an electronic blocking oscillator circuit for maintaining the oscillations of a mechanical oscillator, e.g. a balance wheel, carrying a magnet, the oscillator circuit comprises a transistor 3 having connected to its base a capacitor 11 in series with a pick-up coil 2, a driving coil 1 connected to its collector, a capacitor 6 connected between its emitter and collector, and a resistor 5 through which the capacitor 7 is charged to render the oscillator circuit oscillating. The magnet is arranged to couple the coils 1, 2 when at its centre of oscillation which position it occupies when at rest. The timepiece is self-starting when the power supply is switched on when the capacitor 7 charges up through the resistor 5, and the capacitor 6 charges up through the coil 1 to induce a current impulse in the coil 2. The potential of the transistor base is thus changed rapidly to render the transistor conducting. A further current pulse passes to the coil 1 and the circuit oscillates in the manner of a blocking oscillator, the pulses in the driving coil 1 impelling the magnet until the latter has swung away from the coils 1, 2 to remove the coupling between the latter so that the oscillations cease. A diode 4 is connected in parallel with the driving coil 1 and a resistor 8 between the emitter and the power supply for temperature and voltage stabilization. The transistor may be of either the NPN or the PNP type.
