Abstract: A switching arrangement and method for setting or adjusting a time-measuring device comprising at least two counters connected one after the other and connected in certain cases with indicator devices, of which one counter changes the counter position thereof by count-pulses emitted by a generator circuit at successive intervals of time and of which the other counter respectively upon transition of the said one counter from one defined counter position into another defined counter position receives a signal fed from the said one counter, which brings about its onward count, and a control device for resetting the said one counter, characterized in that the counting-range of the said one counter is divided up into two partial ranges of preferably at least approximately equal size, in one of which the said one counter emits a defined first output signal and in the other of which the one counter in question emits a defined second output signal, and that the control device resets the one counter in question out of

Abstract: A circuit for synchronizing an electrodynamic clockwork drive including two inductors and two permanent magnet assemblies which are moved relative to a clockwork drive by a mechanical oscillation system having the inherent frequency f and the first inductor is disposed in the operating circuit of a switching transistor and the second inductor is disposed in its control circuit so that current pulses induced in the second inductor trigger the switching transistor.
