Electric discharge device

Claim 2

AN ARC DISCHARGE DEVICE COMPRISING AN ENVELOPE, AN ANODE IN SAID ENVELOPE, A LIQUID POOL CATHODE IN SAID ENVELOPE, MEANS FOR VAPORIZING THE MATERIAL OF SAID CATHODE TO EFFECT AN ARC DISCHARGE BETWEEN SAID ANODE AND CATHODE, MEANS FOR COOLING SAID ENVELOPE TO CONDENSE THE VAPORIZED CATHODE MATERIAL, AND A QUANTITY OF GETTER MATERIAL ADAPTED FOR REVERSIBLY SORBING HYDROGEN AND HYDROGEN-CONTAINING GASES IN A PREDETERMINED TEMPERATURE RANGE SUPPORTED ON THE INNER SURFACE OF SAID ENVELOPE, SAID ENVELOPE HAVING A RELATIVELY LARGE PORTION OF THE INTERNAL SURFACE THEREOF OPERABLE DURING OPERATION OF SAID DEVICE AT AN ELEVATED TEMPERATURE IN THE EFFECTIVE GAS DESORPTION RANGE OF SAID GETTER MATERIAL, SAID GETTER MATERIAL COVERING SUBSTANTIALLY LESS THAN ALL OF SAID INNER SURFACE OF SAID ENVELOPE, AND MOST OF SAID PORTION OF SAID INTERNAL SURFACE BEING FREE OF GETTER MATERIAL.

Claim 3

AN ARC DISCHARGE DEVICE COMPRISING AN ENVELOPE ON THE INNER SURFACE OF WHICH LIQUID IS CONDENSED DURING OPERATION, MEANS FOR COOLING SAID SURFACE TO FACILITATE CONDENSATION OF SAID LIQUID, AN ANODE AND A LIQUID-POOL CATHODE ARRANGED IN MUTUALLY INSULATED COOPERATING RELATION IN SAID ENVELOPE, MEANS FOR VAPORIZING THE MATERIAL OF SAID CATHODE AND ESTABLISHING AN ARC BETWEEN SAID ANODE AND AN ACTIVE PORTION OF SAID CATHODE, WALL MEANS IN SAID ENVELOPE INTERCEPTING CONDENSATE DRAINING FROM THE INNER SURFACE OF SAID ENVELOPE AND ANY OTHER MATERIAL CARRIED THEREBY AND MAINTAINING SAID INTERCEPTED CONDENSATE SEPARATE FROM SAID LIQUID-POOL CATHODE, SAID WALL MEANS HAVING BARRIER MEANS ASSOCIATED THEREWITH TO PROVIDE ADDITIONAL SEPARATION OF SAID INTERCEPTED CONDENSATE INTO TWO PORTIONS SO THAT FLOW OF SAID CONDENSATE FROM ONE PORTION TO THE OTHER MUST TAKE PLACE BELOW SAID BARRIER IN SAID CONDENSATE, SAID BARRIER MEANS CONFINING SAID OTHER MATERIAL TO ONE OF SAID PORTIONS, SAID WALL MEANS HAVING OPENING MEANS THEREIN SPACED ABOVE THE LOWER END OF SAID BARRIER TO PROVIDE FLOW OF CONDENSATE FROM THE OTHER OF SAID PORTIONS INTO SAID LIQUID-POOL CATHODE, SAID BARRIER MEANS CONFINING SAID OTHER MATERIAL ADJACENT SAID COOLED WALL AND REMOTE FROM SAID ACTIVE CATHODE.

Claim 4

AN ARC DISCHARGE DEVICE COMPRISING AN ENVELOPE ON THE INNER SURFACE OF WHICH LIQUID IS CONDENSED DURING OPERATION, MEANS FOR COOLING SAID SURFACE TO FACILITATE CONDENSATION OF SAID LIQUID, AN ANODE AND A LIQUID-POOL CATHODE ARRANGED IN MUTUALLY INSULATED COOPERATING RELATION IN SAID ENVELOPE, MEANS FOR VAPORIZING THE MATERIAL OF SAID CATHODE AND ESTABLISHING AN ARC BETWEEN SAID ANODE AND AN ACTIVE PORTION OF SAID CATHODE, WALL MEANS IN SAID ENVELOPE INTERCEPTING CONDENSATE DRAINING FROM THE INNER SURFACE OF SAID ENVELOPE AND ANY OTHER MATERIAL CARRIED THEREBY AND MAINTAINING SAID INTERCEPTED CONDENSATE SEPARATE FROM SAID LIQUID-POOL CATHODE, SAID WALL MEANS HAVING BARRIER MEANS ASSOCIATED THEREWITH TO PROVIDE ADDITIONAL SEPARATION OF SAID INTERCEPTED CONDENSATE INTO TWO PORTIONS SO THAT FLOW OF SAID CONDENSATE FROM ONE PORTION TO THE OTHER MUST TAKE PLACE BELOW SAID BARRIER IN SAID CONDENSATE, SAID BARRIER MEANS CONFINING SAID OTHER MATERIAL TO ONE OF SAID PORTIONS, SAID WALL MEANS HAVING OPENING MEANS THEREIN SPACED ABOVE THE LOWER END OF SAID BARRIER TO PROVIDE FLOW OF CONDENSATE FROM THE OTHER OF SAID PORTIONS INTO SAID LIQUID-POOL CATHODE, SAID BARRIER MEANS CONFINING SAID OTHER MATERIAL ADJACENT SAID COOLED WALL AND REMOTE FROM SAID ACTIVE CATHODE.
