DEFINITION

Classification: 331/55

(under subclass 46) Subject matter wherein at least one of a plurality of oscillators is provided with means for coupling the oscillator, or oscillators, to a periodic source of synchronizing or triggering potential to drive to lock the period of the oscillator, or oscillators, to the period of the source or to some multiple or submultiple thereof.

SEE OR SEARCH THIS CLASS, SUBCLASS:

18+, for oscillators of the automatic frequency stabilized type synchronized with respect to a standard or reference frequency source.

41, for beat frequency oscillators that are locked to synchronize with a standard or reference frequency.

50+, for cascade or tandem connected oscillators.

87, for magnetron type oscillators with means to pulse the oscillator.

145, for multivibrators with synchronizing, triggering or pulsing circuit. 149, for blocking oscillators with synchronizing, triggering or pulsing circuits.

153, for relaxation oscillators in general with synchronizing, triggering or pulsing means.

172+, for oscillators in general with synchronizing, triggering or pulsing means.
