发明名称 PROCEDIMENTO E DISPOSITIVO PER LA SINCRONIZZAZIONE DI UN OROLOGIO PRINCIPALE E OROLOGI SECONDARI COMANDATI DA ESSO
摘要 The invention relates to a method and a device for time distribution, consisting of a quartz master clock, which is characterized in that this master clock determines the time in absolute value with the change in instantaneous time and, on the other hand, sets the slave clocks by sequential steps, in particular in the case of the stoppage or change of time, and which has a first main counter (6) which enables the change of the instantaneous time, and a second, follow-up counter (12) which controls the slave clocks in a temporally resettable fashion by successive steps, the said follow-up counter (12) being supplied via an electric circuit (13) which serves it, and its displays are continuously controlled with those of the main counter (6) by means of a comparator (15), provided for this purpose, in such a way that the follow-up counter (12) follows the main counter (6). <IMAGE>
