Abstract: 1311356 Electro-mechanical oscillators for timepieces. BUNKER-RAMO CORP 18 May 1970 [6 June 1969 11 March 1970] 23907/70 Heading G3T An electro-mechanical oscillator e.g. for a timepiece comprises a non-magnetic balance wheel 20, Fig.1, biased by a spring 26 and carrying a permanent magnet 18 and counterweight 24. The magnet co-operates with drive coil 16 and sensing coil 14 coaxially disposed on a non-ferrous or air core and connected in series opposition. The balance wheel staff 22 is provided with a ladder escapement for driving a timepiece gear train. The oscillator system may be started by physically displacing the balance wheel or by momentarily connecting the emitter and collector of a transistor 4 by means of a switch (not shown) whereby a current pulse from a source 8 through the drive coil 16 repels magnet 18. As the magnet moves past the coil a decreasing field induces e.m.f. in sensing coil 14 which renders Tr 4 conductive causing current to flow in the drive coil 16 and thus further decreasing the field linking sensing coil 14 and increasing the e.m.f. induced therein. This further increases the base voltage of Tr 4 and drives the transistor to saturation. A pulse of energy from drive coil 16 is applied to the balance wheel system to maintain it in operation. As soon as the induced e.m.f. drops to a low level the electrical oscillation ceases and the transistor becomes non-conductive.

[Classes 35 and 38 (iv)] [See also Groups XXXVII and XL] Machines with vapour or like rectifiers in place of commutators.-In a ship propulsion system, propeller motors 40, 41, are supplied from engine-driven alternators 19-22 through grid-controlled discharge devices 38, 39, 42, 43, and speed-controlled by controlling the grids of these devices in two stages so that for one stage the armature currents remain constant, while the field strengths are varied, and for the other stage, the field strengths remain constant while the armature currents are varied. During the former controlling stage ammeters in the armature circuits may actuate contacts controlling a servo-motor which adjusts grid-controlling devices 45, 46, to maintain the armature currents constant. The anodes of the discharge devices 38, 39, may be divided into two groups, control being first effected on both groups, and then with one group carrying no current the control is repeated on the other group. The system is applicable to motors in which commutation is effected by grid-controlled discharge devices. In this case different phases of the motors may be rendered currentless for the several speed stages. For low speed operation the motors may be supplied in series from one of the grid-controlled discharge devices 38, 39, only. Also for power factor improvement certain of the alternators are uncoupled from their engines and run as wattless current machines.
