Electric discharge tube equipped with anode cooled by the boiling cooling principle

Claim 1

AN ELECTRIC DISCHARGE TUBE EQUIPPED WITH AN ANODE WHICH IS COOLED BY THE BOILING COOLING PRINCIPLE, THE TUBE COMPRISING, IN COMBINATION: A TANK, AND AN ANODE ARRANGED IN SAID TANK, SAID ANODE BEING CONSTITUTED BY TWO VERTICALLY ORIENTED CONCENTRIC CYLINDERS WHICH ARE CONNECTED TOGETHER ACROSS THE TOP, THEREBY TO FORM AN ANODE OF INVERTED U-SHAPED CROSS SECTION, THERE BEING ARRANGED WITHIN THE ANNULAR SPACE FORMED BETWEEN SAID TWO CYLINDERS A CATHODE THAT EMITS RADIALLY IN BOTH DIRECTIONS; A PLATE CLOSING THE LOWER END OF THE INNER OF SAID TWO CONCENTRIC CYLINDERS FOR FORMING A VACUUM TIGHT SEAL FOR THE ANODE AND CATHODE; THERE BEING AN OUTER COOLANT CHAMBER FORMED BETWEEN THE OUTER SURFACE OF THE OUTER ONE OF SAID TWO CONCENTRIC CYLINDERS AND THE INNER SURFACE OF SAID TANK WITHIN WHICH SAID ANODE IS ARRANGED, AND THERE BEING AN INNER COOLANT CHAMBER FORMED WITHIN THE CYLINDRICAL SPACE DEFINED BY THE INNER SURFACE OF THE INNER OF SAID TWO CONCENTRIC CYLINDERS AND SAID PLATE; SAID OUTER CYLINDER BEING PROVIDED, IN THE REGION OF SAID OUTER SURFACE THEREOF, WITH A PLURALITY OF CIRCUMFERENTIALLY DISTRIBUTED, AXIALLY EXTENDING COOLING CHANNELS WHOSE LOWER ENDS COMMUNICATE WITH SAID OUTER COOLANT CHAMBER; AND SAID INNER CYLINDER BEING PROVIDED, IN THE REGION OF SAID INNER SURFACE THEREOF, WITH A PLURALITY OF FURTHER CIRCUMFERENTIALLY DISTRIBUTED, AXIALLY EXTENDING COOLING CHANNELS WHOSE LOWER ENDS COMMUNICATE WITH SAID INNER COOLANT CHAMBER; IN CONSEQUENCE OF WHICH COOLANT IN SAID COOLANT CHAMBERS WILL, UPON HEATING UP OF SAID ANODE CYLINDERS AND THE RESULTANT VAPORIZATION OF SOME OF THE COOLANT IN SAID CHANNELS, BE DRAWN INTO SAID CHANNELS.
