Claim 1
Independent Claim

THE METHOD OF OPERATING AN ELECTRIC MELTING FURNACE WHICH INCLUDES THE STEPS OF GENERATING AN ELECTRIC ARC ZONE AT AN ELEVATED TEMPERATURE BY ENERGIZING A CIRCUIT INCLUDING THE CONTENTS OF THE FURNACE AND AN ELECTRODE, INJECTING A STREAM OF MONATOMIC GAS AT INCREASED PRESSURE INTO THE ELECTRIC ARC ZONE THROUGH THE ELECTRODE SO THAT THE MONATOMIC GAS MOLECULE COLLIDE WITH THE ELECTRONS IN THE ARC ZONE TO SUBSTANTIALLY INCREASE THE TEMPERATURE OF THE ARC ZONE, AND GRAVITATIONALLY INJECTING MATERIALS TO BE MELTED THROUGH SAID ELECTRODE INDEPENDENTLY OF SAID STREAM OF MONATOMIC GAS INTO SAID ZONE.
