[Also in Group XL(c)] In a timepiece the mechanical oscillator e.g. the balance, controls a transistor blocking oscillator which supplies the maintaining impulses. In the first example, Fig. 1, the blocking oscillator circuit includes a transistor T, two transformers 4, 5 each having two windings and providing normally balanced positive and negative feedback, a battery B, a blocking capacitor C, a voltage divider R1, R2 and a diode D which if it is of the semi-conductor type may be integral with the transistor which may be of silicon. A magnetic conductor 2 on the balance enters an air gap of the transformer 4 and thereby increases the inductance of the winding L1 to trigger the oscillator which impulses the balance. The maintaining impulses each comprise a driving component, and a braking component the difference between which constituting the effective impulse and being inversely proportional to the balance amplitude which is thus kept substantially constant. The core of the first transformer 4 may be constructed as shown in Fig. 4 to co-operate with lugs 1c on the balance 1. In a modification Fig. 6 (not shown) the lugs 1c are vertical and the transformer core comprises two U-shaped members. The balance may comprise three discs which co-operate with two pole shoes of the transformer core. The blocking oscillator circuit may be modified as shown in Fig. 7 to have only one negative feedback winding L3 and biasing resistors R1, R2 the latter of which comprises two components one of which has a negative temperature coefficient. The blocking oscillator may be arranged to have a constant feedback, the amplification of the transistor normally being insufficient for self-excitation but being triggered by the charging or discharging current of a capacitor C2, Fig. 9, an actuation of a switch S. The switch may comprise a piezo-electric crystal which is engaged by a cam on the balance staff. In another example Fig. 13, the switch S comprises a contact k1 carried by the balance roller to co-operate with the limbs Z1, Z2 of the forked end of the lever a. In the free swing of the balance the lever a is retained against a banking pin X1 or X2 by a magnet n on the lever. The lever a carries a driving pawl St which drives the gear Rd.
