    摘要： A timepiece includes a mechanical oscillator, formed of a mechanical resonator, and a device for regulating the frequency of the mechanical oscillator. This regulation device includes an auxiliary oscillator, an electromechanical device for stopping the mechanical resonator, a sensor arranged to detect the passage of the mechanical resonator via the neutral position thereof, and a measuring device arranged to measure a time drift of the mechanical oscillator. The regulation device is arranged to stop, during a given alternation, the natural oscillation movement of the mechanical resonator selectively either momentarily during a first half-alternation occurring before the passage of the mechanical resonator via the neutral position thereof when the time drift measured corresponds to at least a certain gain, or prematurely during a second half-alternation occurring after the passage of the mechanical resonator via the neutral position thereof when the time drift measured corresponds to at least a certain loss.

    摘要： Synchronization apparatus for a motor comprising a maintenance circuit furnishing to the motor the necessary energy for its rotation and delivering a frequency fm proportional to its speed, and utilizing a precise frequency fp furnished, for example, by a quartz oscillator connected to a frequency divider. Connected to a bistable phase comparator are the output frequency f1 = fp/x of a divider by x, and the output of frequency f2 of a divider by x + .alpha. to the input of which divider there is added .alpha.y impulses to each cycle of the frequency fm. The output of the phase comparator acts on the maintenance circuit such as to interrupt or re-establish the distribution of the energy to the motor according to whether this output is in one state or the other such that f2 is equal and in phase with f1 and fm is sychronized to a mean value equal to fp/xy for which .alpha., x, and y are whole numbers.

    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： A MINIATURE TIMEPIECE DRIVEN BY A TUNING-FORK MOTOR WHOSE VIBRATORY ACTION IS ELECTROMAGNETICALLY SUSTAINED BY AN ELECTRONIC DRIVE CIRCUIT. TO REGULATE THE TIMING RATE OF THE MOTOR, A FREQUENCY STANDARD IS PROVIDED IN THE FORM OF A CRYSTAL OSCILLATOR WHOSE FREQUENCY IS AN EXACT MULTIPLE OF THE PRESCRIBED TIMING FREQUENCY OF THE MOTOR. THE MOTOR IS PRESET TO OPERATE AT A TIMING RATE DISPLACED TO ONE SIDE OF THE PRESCRIBED FREQUENCY TO A DEGREE DETERMINED BY THE MAXIMUM ANTICIPATED DEVIATION IN TIMING RATE CHARACTERISTIC OF THE MOTOR. TO EFFECT REGULATION, PULSES ARE DERIVED FROM THE ELECTRONIC CIRCUIT, THE PULSES HAVING A PERIODICALLY EQUAL TO THE OPERATING FREQUENCY OF THE FORK. THESE PULSE ARE COMPARED IN A COINCIDENCE CIRCUIT WITH THE STANDARD OSCILLATIONS TO PRODUCE AN ERROR SIGNAL ONLY WHEN THE PULSE ARE DISPLACED IN PHASE FROM THE PARTICULAR SUBMULTIPLE OF OSCILLATIONS WHICH CORRESPONDS TO THE PRESCRIBED FREQUENCY. THE ERROR SIGNAL ACTIVATES A FREQUENCY-CORRECTION CIRCUIT COUPLED TO THE ELECTRONIC DRIVE CIRCUIT ASSOCIATED WITH THE TUNING-FORK MOTOR, WHEREBY THE PHASE OF THE PULSE DERIVED FROM THE ELECTRONIC CIRCUIT SHIFTS IN A DIRECTION TO BRING ABOUT PHASE-LOCKING WITH SAID SUBMULTIPLE.

    摘要： A frequency-to-digital converter is disclosed wherein the frequency of an external signal is digitized by coupling the signal to a priority or program interrupt or signalling channel of a digital computer and connecting internal or external clock pulses to a memory increment or program interrupt channel. The computer is programmed to calculate the number of clock pulses between successive rises of the input signal. Thus, the number of clock pulses is a measure of the period of the input signal which is the reciprocal of the instantaneous frequency.
