Temperature compensated microwave cavity

Claim 2

A TEMPERATURE COMPENSATED MICROWAVE CAVITY RESONATOR COMPRISING, A GENERALLY HOLLOW CYLINDRICAL CONDUCTING STRUCTURE HAVING A FIXED END WALL AND AN OPPOSITELY DISPOSED AXIALLY MOVABLE CONFRONTING END WALL, AN EXPANSIBLE AXIALLY MOVABLE PLUG DISPOSED ADJACENT SAID MOVABLE END WALL AND EXTERNALLY OF THE CAVITY RESONATOR DEFINED BETWEEN SAID FIXED AND MOVABLE END WALLS, MEANS FOR URGING ONE END OF SAID PLUG AND SAID MOVABLE END WALL INTO ENGAGEMENT, AND COOPERATING MEANS ON SAID PLUG AND ON SAID CYLINDRICAL STRUCTURE FOR FIXING A DIFFERENT EXPANSIBLE AXIAL LENGTH OF SAID PLUG FOR CONTROLLING THE AXIAL POSITION OF SAID MOVABLE END WALL IN EACH OF A PLURALITY OF CONTIGUOUS TEMPERATURE RANGES.

Claim 3

A TEMPERATURE COMPENSATED MICROWAVE CAVITY RESONATOR COMPRISING, A GENERALLY HOLLOW CYLINDRICAL STRUCTURE HAVING A FIXED END WALL, SUPPORT MEANS AFFIXED TO SAID CYLINDRICAL STRUCTURE AT THE END OPPOSITE SAID FIXED END WALL, A HOLLOW CYLINDRICAL EXPANSIBLE MEMBER EXTENDING AXIALLY INWARD FROM SAID SUPPORT MEANS TOWARD SAID FIXED END WALL AND FORMED AT ITS INNER END WITH AN OUTSTANDING CENTRAL HUB AND A OUTSTANDING SHOULDER CONFRONTING GENERALLY WITH THE INTERNAL DIMENSION OF SAID HOLLOW CYLINDRICAL STRUCTURE, A FLEXIBLE CONDUCTING MEMBER RIGIDLY SECURED AT ITS EDGE TO SAID SHOULDER AND NORMALLY URGED TOWARD AND CONTACTING SAID HUB AT ITS CENTER, THE INNER CONFRONTING FACES OF SAID FLEXIBLE MEMBER AND SAID FIXED END WALL DEFINING SAID CAVITY RESONATOR BETWEEN THEM, AND AN AXIALLY EXPANSIBLE ROD OF DIFFERENT TEMPERATURE COEFFICIENT OF EXPANSION EXTENDING AXIALLY THROUGH SAID HOLLOW CYLINDRICAL EXPANSIBLE MEMBER AND FIXED AT ONE END RELATIVE TO SAID SUPPORT MEANS, THE OTHER END OF SAID ROD EXTENDING THROUGH SAIDHUB INTO CONTAINING RELATION WITH SAID FLEXIBLE CONDUCTING MEMBER, WHEREBY IN ONE TEMPERATURE RANGE THE AXIAL DIMENSION OF SAID HOLLOW CYLINDRICAL EXPANSIBLE MEMBER SOLELY CONTROLS THE RELATIVE AXIAL POSITION OF SAID FLEXIBLE MEMBER WHILE IN A SECOND CONTIGUOUS TEMPERATURE RANGE SAID HOLLOW CYLINDRICAL EXPANSIBLE MEMBER AND SAID EXPANSIBLE ROD JOINTLY CONTROL THE RELATIVE AXIAL POSITION OF SAID FLEXIBLE MEMBER.

Claim 4

A TEMPERATURE COMPENSATED MICROWAVE CAVITY RESONATOR COMPRISING, A GENERALLY HOLLOW CYLINDRICAL STRUCTURE HAVING A FIXED END WALL, SUPPORT MEANS AFFIXED TO SAID CYLINDRICAL STRUCTURE AT THE END OPPOSITE SAID FIXED END WALL, A HOLLOW CYLINDRICAL EXPANSIBLE MEMBER EXTENDING AXIALLY INWARD FROM SAID SUPPORT MEANS TOWARD SAID FIXED END WALL AND FORMED AT ITS INNER END WITH AN OUTSTANDING CENTRAL HUB AND A OUTSTANDING SHOULDER CONFRONTING GENERALLY WITH THE INTERNAL DIMENSION OF SAID HOLLOW CYLINDRICAL STRUCTURE, A FLEXIBLE CONDUCTING MEMBER RIGIDLY SECURED AT ITS EDGE TO SAID SHOULDER AND NORMALLY URGED TOWARD AND CONTACTING SAID HUB AT ITS CENTER, THE INNER CONFRONTING FACES OF SAID FLEXIBLE MEMBER AND SAID FIXED END WALL DEFINING SAID CAVITY RESONATOR BETWEEN THEM, AND AN AXIALLY EXPANSIBLE ROD OF DIFFERENT TEMPERATURE COEFFICIENT OF EXPANSION EXTENDING AXIALLY THROUGH SAID HOLLOW CYLINDRICAL EXPANSIBLE MEMBER AND FIXED AT ONE END RELATIVE TO SAID SUPPORT MEANS, THE OTHER END OF SAID ROD EXTENDING THROUGH SAIDHUB INTO CONTAINING RELATION WITH SAID FLEXIBLE CONDUCTING MEMBER, WHEREBY IN ONE TEMPERATURE RANGE THE AXIAL DIMENSION OF SAID HOLLOW CYLINDRICAL EXPANSIBLE MEMBER SOLELY CONTROLS THE RELATIVE AXIAL POSITION OF SAID FLEXIBLE MEMBER WHILE IN A SECOND CONTIGUOUS TEMPERATURE RANGE SAID HOLLOW CYLINDRICAL EXPANSIBLE MEMBER AND SAID EXPANSIBLE ROD JOINTLY CONTROL THE RELATIVE AXIAL POSITION OF SAID FLEXIBLE MEMBER.
