Ferrite modulators for deviating magnetrons

Claim 1

IN COMBINATION, A WAVEGUIDE ADAPTED TO RECEIVE MICROWAVE ENERGY, A FIRST ROTATING ELEMENT FOR ROTATING SAID MICROWAVE ENERGY THROUGH AN ANGLE OF FORTY-FIVE DEGREES CONNECTED TO ONE END OF SAID WAVEGUIDE, FIRST AND SECOND T-SECTIONS OF WAVEGUIDE EACH HAVING A PAIR OF CROSSPOLARIZED INPUT ARMS AND AN OUTPUT ARM, AN INPUT ARM OF THE FIRST OF SAID SECTIONS ADAPTED TO BE CONNECTED TO THE OUTPUT OF SAID FIRST ROTATING ELEMENT, SAID WAVEGUIDE ROTATED A PREDETERMINED ANGULAR DISTANCE WITH RESPECT TO ONE OF THE POLARIZATIONS OF MICROWAVE ENERGY IN SAID FIRST T-SECTION, A LOAD CONNECTED TO THE OUTPUT ARM OF SAID SECOND SECTION, A SECOND ROTATING ELEMENT INTERPOSED BETWEEN AND CONNECTED TO THE OUTPUT ARM OF SAID FIRST SECTION AND AN INPUT ARM OF SAID SECOND SECTION, A RETURN SECTION OF WAVEGUIDE CONNECTING AN INPUT ARM OF SAID FIRST AND SECOND SECTIONS OTHER THAN THE ARMS TO WHICH SAID ROTATING ELEMENTS ARE ALREADY CONNECTED, SAID SECOND ROTATING ELEMENT ADAPTED TO PROVIDE A FIXED ROTATION OF A PREDETERMINED NUMBER OF DEGREES, AND AN ALTERNATING MAGNETIC FIELD APPLIED TO SAID SECOND ROTATING ELEMENT WHEREBY A PORTION OF THE MICROWAVE ENERGY IN SAID SECOND ROTATING ELEMENT IS RETURNED TO SAID FIRST ROTATING ELEMENT.
