摘要： Synchronizable clock with a mechanical resonator as regulator, especially receiver clocks synchronized by wireless signals and synchronous clocks driven by alternating current having a mechanical regulator forming a principal part of a running reserve. A coupling is provided between the resonator and the hand mechanism, which only transmits one half of the counting impulses. There is also a regulating mechanism which is connectable to the resonator and which alters the spring force in the resonator according to intensity and position in proportion to the oscillating masses in such a manner that a reversal of the motion of the oscillating masses occurs in the region of the normal dead center.
摘要翻译：具有作为调节器的机械谐振器的同步时钟，特别是通过无线信号同步的接收器时钟和由交流电驱动的同步时钟，其具有形成运行储备的主要部分的机械调节器。在谐振器和手机构之间提供耦合，其仅传输计数脉冲的一半。还有一种调节机构，其可连接到谐振器，并且根据与振荡块成比例的强度和位置改变谐振器中的弹簧力，使得振荡块的运动反转在该区域中发生的正常死亡中心。

摘要： AN ELECTRONIC CLOCK CONTROLLED BY PERIODIC WIRELESS TIME SIGNALS, THE SIGNALS COMPRISING MODULATIONS OF A CARRIER WAVE, THE MODULATIONS OCCURRING ONCE EVERY SECOND, AN ADDITIONAL MODULATION OCCURRING IN THE FIRST SECOND OF EVERY MINUTE IN ORDER TO MARK THE BEGINNING OF THE MINUTE, THE ELECTRONIC CLOCK FURTHER COMPRISING A HF RECEIVER, A DETECTOR TO TRANSFORM THE MODULATIONS INTO A SECOND PULSE EVERY SECOND AND INTO A SECOND PULSE FOLLOWED BY MINUTE PULSE AT THE BEGINNING OF EVERY MINUTE, A STEP-BY-STEP MOTOR DRIVING MEANS, THE MOTOR DRIVING MEANS INCLUDING MEANS FOR VISUALLY INDICATING THE TIME, THE DETECTOR INCLUDING MEANS FOR CONTROLLING THE MOTOR MEANS, CIRCUIT MEANS FOR ADJUSTING THE INDICATING MEANS IN THE EVENT OF LACK OF SYNCHRONIZATION BETWEEN THE SIGNALS AND THE TIME INDICATIONS, THE CIRCUIT MEANS INCLUDING MEANS FOR SELECTING THE MINUTE PULSES FROM THE SECOND PULSES, THE SELECTING MEANS INCLUDING TWO INPUTS AND AN OUTPUT, MEANS FOR REPRODUCING A MINUTE PULSE AT THE OUTPUT WHEN THE SELECTING MEANS IS SIMULTANEOUSLY EXCITED BY A MINUTE PULSE AT ONE INPUT AND BY A PULSE COMPLEMENTRY TO ONE OF THE SECOND PULSES AT THE OTHER INPUT, THE ADJUSTING CIRCUIT INCLUDING MEANS FOR TRANSDUCING THE SELECTED MINUTE PULSES INTO SIGNALS COMPARABLE WITH THE POSITION OF THE TIME INDICATING MEANS SO AS TO DETECT A LACK OF SYNCHRONIZATION.
