Patent GB-690464-A (GB)
Title: Winding and setting mechanism with rocking-bar for watch or clock movements
IPC: G04B27/06
Filed: 1951-09-26
Abstract: 690,464. Timepieces. EBAUCHES SOC. ANON. Sept 26, 1951 [March 7, 1951]. No. 22481/51. Class 139. A winding and setting mechanism of the rocking-bar type is characterized in that the square head of the winding stem is so shaped that during the return motion of the winding stem from the setting position to the winding position the intermediate setting wheel pivoting on the rocking bar cannot actuate the hands of said watch or clock movement nor prevent the return movement of the rocking bar. In the first example, Fig. 1, the winding stem 9 has a square head 10 of helicoidal form so that when the stem is depressed, from the setting position to the winding position the ,crown pinion 8 is rotated slightly to impart through the transmission wheel 7 a clockwise movement to the intermediate setting wheel 3 thus cancelling out the simultaneous counterclockwise movement of the wheel caused by its rolling on this wheel 7 as the rocking bar 1 moves back. No movement is therefore imparted to the minute wheel 6 as the setting bar 1 rocks clockwise. In a second example, Fig. 2, the square head 16 of the winding stem 9 is the shape of a truncated pyramid so that when the stem is depressed the pinion 8 has a sufficient play to allow the transmission wheel to yield and prevent rotation of the intermediate setting wheel.

Abstract: 945,405. Transistor bi-stable circuits. WESTINGHOUSE ELECTRIC CORPORATION. June 23, 1961 [July 18, 1960], No. 22866/61. Heading H3T. [Also in Division H2] A control circuit for supplying steep-fronted pulses to controllable rectifier elements in a rectifier bridge comprises a magnetic amplifier MA1 having output windings WO1, WO2 which provide signals to control the conduction of transistors TR1, TR2 in a bi-stable flip-flop circuit which includes feedback resistors R12, R13 and an output transformer T2. As shown an A.C. supply L1, L2 is fed to a rectifier bridge whose arms comprise diodes D3, D4 and semi-conductor controlled rectifiers TN1, TN2 in series with diodes D1, D2. Pulses from secondary windings T251, T252 are fed to the gate-cathode circuits through diodes D9, D10 which suppress negative signals. Diodes D59, D69 across TN1, TN2 suppress reverse potentials. The A.C. supply is also fed to a transformer T1 which supplies through diodes D39, D49 a D.C. supply for the transistors and a variable D.C. bias for the magnetic amplifier. The transistors are cross-coupled through the resistors R12, R13. Output windings WO1, W02 are connected in series with diodes D19, D29 and resistors R5, R6 to the A.C. supply. A current is set through winding WC to control the instant in the positive half-cycle when winding WO1 develops a pulse to provide a voltage across diode 15 to cut-off transistor TR1 which is at that time conducting. Transistor TR2 is switched on and an output pulse of 30 degrees duration is developed in the windings T251, T252 of the output transformer. During the next half-cycle winding WO2 develops a pulse. The pulse instant is variable through 160 degrees of the half-cycle. In a modification (Fig. 3, not shown), provision for operation of the bi-stable circuit in the absence of a signal from the magnetic amplifier is provided by a saturable transformer T3 fed from the A.C. supply through a phase-shifting network, the transformer supplying signals to block the conducting transistor. In Fig. 3, each arm of the rectifier bridge includes a controllable rectifier.
