Coaxial transmission line termination employing tubular resistor cooled by internal and external annular water films

Claim 1

A MICROWAVE ENERGY DISSIPATING APPARATUS COMPRISING, A TUBULAR FILM-TYPE RESISTOR WHICH INCLUDES A RESISTANCE FILM AT THE OUTER WALL OF A TUBE OF INSULATING MATERIAL, A HOLLOW TAPERED OUTER CONDUCTOR BODY SURROUNDING SAID RESISTOR AND ELECTRICALLY CONNECTED THERETO AT ONE END, A TAPERED SOLID DIELECTRIC BODY HAVING AN AXIAL BORE THERETHROUGH POSITIONED WITHIN THE TAPERED OUTER CONDUCTOR BETWEEN THE TAPERED OUTER CONDUCTOR AND RESISTOR, THE WALL OF SAID BORE BEING SPACED FROM THE SAID RESISTANCE FILM TO FORM A THIN ANNULAR PASSAGE, SAID TAPERED SOLID DIELECTRIC BODY SUBSTANTIALLY COMPLETELY FILLING THE SPACE BETWEEN SAID TAPERED OUTER CONDUCTOR AND SAID TUBULAR RESISTOR EXCEPT FOR SAID THIN ANNULAR PASSAGE, A GENERALLY CYLINDRICALLY SHAPED ROD OF DIELECTRIC MATERIAL COAXIALLY POSITIONED WITHIN SAID TUBULAR RESISTOR AND SPACED THEREFROM TO FORM A THIN ANNULAR PASSAGE, MEANS FORMING A PASSAGE INTERCONNECTING SAID THIN ANNULAR PASSAGES ADJACENT ONE END OF SAID RESISTOR, AND FIRST AND SECOND MEANS FORMING PASSAGES FOR INTRODUCTION AND DISCHARGE, RESPECTIVELY, OF A STREAM OF DIELECTRIC LIQUID TO AND FROM SAID THIN ANNULAR PASSAGES.
