Claim 1
Independent Claim
110 words
THE METHOD OF CONCENTRATING A PARTICULAR ISOTOPE OF AN ELEMENT SELECTED FROM THE GROUP CONSISTING OF BORON AND OXYGEN WHICH COMPRISES FORMING A LIQUID COMPLEX COMPOUND CONTAINING BORON AND OXYGEN THAT IS CAPABLE OF DISSOCIATING REVERSIBLY IN THE VAPOR PHASE AND HAS SUBSTANTIALLY THE SAME CHEMICAL COMPOSITION IN THE LIQUID AND VAPOR PHASE, HEATING SAID COMPLEX COMPOUND TO CONVERT A PORTION THEREOF INTO THE VAPOR PHASE, AND ESTABLISHING A COUNTERCURRENT FLOW OF SAID LIQUID PHASE AND SAID WET VAPOR PHASE WHILE MAINTAINING SAID LIQUID AND SAID VAPOR IN INTIMATE CONTACT WITH ONE ANOTHER, WHEREBY ONE OF SAID ISOTOPES OF ONE OF SAID ELEMENTS TENDS TO CONCENTRATE IN THE VAPOR PHASE.
