Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
131 words
A METHOD OF PRODUCING CLAD METAL COMPRISING THE STEPS OF SPRAYING A NON-REFRACTORY MOLTEN METAL SELECTED FROM THE GROUP CONSISTING OF NICKEL, COPPER AND MIXTURES THEREOF ON AT LEAST ONE SURFACE OF A METAL PLATE OF THE CLASS CONSISTING OF CARBON AND LOW ALLOY STEELS, SAID MOLTEN METAL BEING SPRAYED UNDER A COVER OF GAS, FORMING A PACK FROM SAID PLATE AND AT LEAST ONE OTHER METAL PLATE WITH THE SPRAYED METAL INTERPOSED BETWEEN SAID PLATES, SUBSTANTIALLY SEALING SAID PACK, ELEVATING THE TEMPERATURE OF SAID SEALED PACK BY HEATING TO A TEMPERATURE OF SAID EVOLVE CARBON MONOXIDE GAS, CONTINUING SAID ELEVATED TEMPERATURE IN SAID PACK UNTIL SAID CARBON MONOXIDE GASES HAVE REDUCED THE OXIDES WITHING SAID PACK AND WHEREBY SAID SPRAYED METAL CONSOLIDATES AND BONDS TO SAID FIRST MENTIONED METAL PLATE.
Claim 2
Independent Claim

Claim 3
Independent Claim
124 words
A METHOD OF PRODUCING CLAD STEEL COMPRISING THE STEPS OF SPRAYING A NON-REFRACTORY MOLTEN METAL SELECTED FROM THE GROUP CONSISTING OF NICKEL, COOPER AND MIXTURES THEREOF ON AT LEAST ONE SURFACE OF A METAL PLATE, SAID MOLTEN METAL BEING SPRAYED UNDER A COVER OF GAS, FORMING A PACK FROM SAID PLATE AND A LEAST ONE OTHER METAL PLATE FROM THE CLASS CONSISTING OF CARBON AND LOW ALLOY STEELS WITH THE SPRAYED METAL INTERPOSED BETWEEN SAID PLATES, SUBSTANTIALLY SEALING SAID PACK, ELEVATING THE TEMPERATURE OF SAID SEALED PACK TO A TEMPERATURE OF ABOUT 2000*-2350*F., CONTINUING SAID ELEVATED TEMPERATURE IN SAID PACK UNTIL CARBON MONOXIDE GASES HAVE REDUCED THE OXIDES WITHIN SAID PACK AND WHEREBY SAID SPRAYED METAL CONSOLIDATES AND BONDS TO SAID FIRST MENTIONED PLATE.
