Magnetron device with output coupling

Claim 1

IN COMBINATION, A RECTANGULAR WAVEGUIDE SECTION, A MAGNETRON DEVICE INCLUDING A PLURALITY OF ANNULAR INSULATORS AND A PLURALITY OF GENERALLY ANNULAR TERMINALS ARRANGED IN ALTERNATE BUTT-SEALED RELATION AND PROVIDING A GENERALLY CYLINDRICAL ENVELOPE FOR SAID DEVICE, ON OF SAID TERMINALS BEING RIGID AND THE OTHER RELATIVELY FLEXIBLE, SAID WAVEGUIDE SECTION HAVING AN APERTURE THERETHROUGH DEFINING A PAIR OF RIM SURFACES, EACH SAID TERMINAL MAKING CIRCUMFERENTIAL CONTACT WITH A RESPECTIVE RIM OF SAID APERTURE IN SAID WAVEGUIDE FOR THEREBY R.F. COUPLING SAID DEVICE TO SAID WAVEGUIDE SECTION, AN ANODE STRUCTURE SUPPORTED FROM SAID RIGID ONE OF SAID TERMINALS WITHIN SAID ENVELOPE AND COMPRISING A PLURALITY OF CIRCUMFERENTIALLY SPACED RADIALLY EXTENDING SEGMENTS, R.F. OUTPUT MEANS COMPRISING A CONDUCTIVE ELEMENT INTERCONNECTING THE INNER PORTION OF SAID FLEXIBLE TERMINAL AND SAID ANODE STRUCTURE AND COOPERASTING WITH ONE OF SAID ANODE SEGMENTS TO DEFINE A TRANSMISSION LINE EXTENDING RADIALLY TOWARD THE INSULATOR BETWEEN SAID TERMINALS AND COAXIALLY ALIGNED WITH THE LONGITUDINAL AXIS OF SAID WAVEGUIDE SECTION, AND SAID INSULATION BETWEEN SAID TERMINALS HAVING THE SURFACE THEREOF COMPLETELY COATED WITH A CONDUCTIVE MATERIAL EXCEPT FOR AN AXEA AXIALLY ALIGNED WITHE SAID TRANSMISSION LINE AND WAVEGUIDE SECTION AND CONSTITUTING AN R.F. OUTPUT WINDOW THEREBETWEEN.
