Gas handling systems for radioactive gases

Claim 1

IN A GAS HANDLING SYSTEM ADAPTED FOR USE WITH A MIXTURE OF RADIOACTIVE ISOTOPES OF XENON AND KRYPTON, THE COMBINATION COMPRISING MEANS FOR HOLDING UP AND FOR COOLING SAID GASES FOR A TIME SUFFICIENT TO PERMIT SUBSTANTIAL RADIOACTIVE DECAY OF AT LEAST THE SHORTER-LIVED ISOTOPES IN SAID MIXTURE, A PLURALITY OF ADSORPTION TANKS, EACH OF SAID TANKS CONTAINING A QUANTITY OF ADSORPTIVE MATERIAL CAPABLE OF ADSORBING SUBSTANTIALLY ALL OF SAID XENON ISOTOPES BUT ONLY A PORTION OF SAID KRYPTON ISOTOPES, RADIOACTIVE GAS SISPOSAL MEANS, VALVED CONDUIT MEANS COUPLED TO ALL OF SAID TANKS FOR CONVEYING SAID ISOTOPES FROM SAID HOLDING AND COOLING MEANS TO A SELECTED ONE OF SAID TANKS FOR ADSORPTION THEREIN, AN ADDITIONAL ADSORPTION TANK CONTAINING A QUANTITY OF ADSORPTIVE MATERIAL FOR ADSORBING SAID ISOTOPES, ADDITIONAL VALVED CONDUIT MEANS COUPLED TO SAID FIRST:MENTIONED TANKS AND TO SAID ADDITIONAL TANK FOR CONNECTING SAID ADDITIONAL TANK IN TANDEM TO AT LEAST ONE OF SAID FIRST-MENTIONED TANKS AND TO SAID DISPOSAL MEANS, THE TOTAL QUANTITY OF SAID ADSORPTIVE MATERIAL IN THE TANDEMLY CONNECTED TANKS BEING SUFFICIENT TO ADSORB SUBSTANTIALLY ALL OF SAID XENON AND SAID KRYPTON ISOTOPES, SAID FIRST-MENTIONED VALVED CONDUIT MEANS AND SAID ADDITIONAL VALVED CONDUIT MEANS BEING COOPERATIVE FOR SELECTIVELY ISOLATING EACH OF SAID FIRST-MENTIONED TANKS FOR A TIME SUFFICIENT TO PERMIT SUBSTANTIAL RADIOCATIVE DECAY OF THE RADIOACTIVE ISOTOPES ADSORBED THEREWITHIN, AND MEANS FOR REGENERATING EACH OF SAID TANKS, WHEREBY EACH OF SAID FIRST-MENTIONED TANKS CAN BE CYCLICALLY OPERATED FOR THE PURPOSES OF ADSORPTION, ISOLATION FOR RADIOACTIVE DECAY, AND REGENERATION.
