Circulator-modulator frequency control system

Claim 1

IN A FREQUENCY STABILIZING SYSTEM THE COMBINATION COMPRISING: A SECTION OF WAVEGUIDE ADAPTED TO SUPPORT ELECTROMAGNETIC WAVE ENERGY IN A PLURALITY OF LINEAR POLARIZATIONS; A FIRST POLARIZATION-SELECTIVE CONNECTION AT A FIRST LOCATION ALONG SAID WAVEGUIDE COUPLED TO A GIVEN ONE OF SAID POLARIZATIONS AT SAID FIRST LOCATION; A SOURCE OF LINEARLY POLARIZED WAVE ENERGY CONNECTED TO SAID FIRST CONNECTION; A SECOND POLARIZATION-SELECTIVE CONNECTIUON AT A SECOND LOCATION ALONG SAID WAVEGUIDE COUPLED TO A POLARIZATION OF LINEARLY POLARIZED WAVE ENERGY THEREIN RELATED BY A FIRST ANGLE TO THE POLARIZATION OF SAID FIRST CONNECTION; COUPLING MEANS FOR SAMPLING A PORTION OF WAVE ENERGY IN SAID SECOND CONNECTION; FERROMAGNETIC MEANS CARRIED BY SAID WAVEGUIDE BETWEEN SAID FIRST AND SECOND LOCATIONS FOR ROTATING THE PLANE OF POLARIZATION OF INCIDENT ELECTROMAGNETIC WAVE ENERGY THROUGH A SECOND ANGLE SUBSTANTIALLY EQUAL TO SAID FIRST ANGLE; FREQUENCY DISCRIMINATOR MEANS CONNECTED BETWEEN SAID COUPLING MEANS AND SAID FERROMAGNETIC MEANS FOR VARYING SAID SECOND ANGLE OF ROTATION IN ACCORDANCE WITH FREQUENCY VARIATIONS OF ENERGY IN SAID COUPLING MEANS; AND MEANS CONNECTED TO SAID WAVEGUIDE DISPOSED BETWEEN SAID SOURCE AND SAID SECOND CONNECTION FOR SELECTIVELY ADJUSTING THE PHASE OF ENERGY PROPAGATED TOWARD AND INCIDENT ON SAID SOURCE.
