Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
113 words
THE METHOD OF PROCESSING HIGH TEMPERATURE FUSING MINERAL MATERIAL INCLUDING DELIVERING THE MATERIAL IN BATCH FORM INTO AN OPEN RECEPTACLE, HEATING THE MATERIAL IN AN UPPER REGION OF THE RECEPTACLE BY ELECTRIC ENERGY INDEPENDENTLY OF THE RECEPTACLE TO MELT THE MATERIAL UNDER CONDITIONS AVOIDING CONTAMINATION OF THE MOLTEN MATERIAL BY REFRACTORY, CONTINUOUSLY DISTRIBUTING THE BATCH MATERIAL OVER THE OPEN AREA OF THE RECEPTACLE TO MAINTAIN A LAYER OF THE BATCH MATERIAL OF UNIFORM THICKNESS ON THE MOLTEN MATERIAL, CONTINUOUSLY DISCHARGING THE MOLTEN MATERIAL FROM A LOWER REGION OF THE RECEPTACLE, AND TRANSFERRING HEAT FROM THE MOLTEN MATERIAL TO PROGRESSIVELY REDUCE THE TEMPERATURE OF THE MOLTEN MATERIAL IN ITS DOWNWARD MOVEMENT THROUGH THE RECEPTACLE.
Claim 2
Dependent Claim
139 words
APPARATUS FOR PROCESSING HIGH TEMPERATURE FUSING MINERAL MATERIAL INCLUDING, IN COMBINATION, A WALLED MELTING CHAMBER HAVING AN OPEN UPPER REGION, A CURRENT CONDUCTING ELEMENT EXTENDING ACROSS AN UPPER ZONE OF THE CHAMBER AND ELECTRICALLY INSULATED FROM THE WALLS OF THE CHAMBER, MEANS FOR FEEDING BATCH MINERAL MATERIAL INTO THE OPEN REGION OF THE CHAMBER AND DISTRIBUTING THE MATERIAL IN COMMINUTED FROM SUBSTANTIALLY UNIFORMLY OVER THE ENTIRE AREA OF THE OPEN REGION OF THE CHAMBER, MEANS FOR SUPPLYING ELECTRIC ENERGY TO SAID ELEMENT TO REDUCE THE BATCH MATERIAL TO A MOLTEN STATE, A STREAM FEEDER IN COMMUNICATION WITH THE MELTING CHAMBER ARRANGED TO DISCHARGE STREAMS OF THE MOLTEN MATERIAL, CONTROL MEANS FOR REGULATING ELECTRIC ENERGY FLOW TO THE CURRENT CONDUCTIVE ELEMENT, AND MEANS ASSOCIATED WITH SAID CHAMBER FOR TRANSFERRING HEAT FROM THE MOLTEN MATERIAL AS IT MOVES THROUGH THE CHAMBER.
