Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
126 words
IN A DEVICE FOR FORMING METAL BY MAGNETIC PRESSURE, ENERGY SOURCE MEANS FOR GENERATING A SLOWLY RISING CURRENT, A FIRST CONDUCTOR RESPONSIVELY CONNECTED TO SAID ENERGY SOURCE MEANS TO PROVIDE A SLOWLY RISING MAGNETIC FIELD CORRESPONDING TO SAID SLOWLY RISING CURRENT, AN ELECTRICALLY CONDUCTIVE METAL WORK PIECE POSITIONED WITHIN SAID MAGNETIC FIELD TO HAVE A CURRENT INDUCED THEREIN CORRESPONDING TO SAID SLOWLY RISING MAGNETIC FIELD, A SECOND CONDUCTOR POSITIONED WITHIN SAID MAGNETIC FIELD, MEANS FOR DISCONNECTING SAID FIRST CONDUCTOR FROM SAID ENERGY SOURCE, SAID MAGNETIC FIELD COLLAPSING WHEN SAID FIRST CONDUCTOR IS DISCONNECTED FROM SAID ENERGY SOURCE, SAID COLLAPSING MAGNETIC FIELD INDUCING CURRENTS IN SAID METAL WORK PIECE AND SAID SECOND CONDUCTOR WHICH INTERACT WITH SAID MATNETIC FIELD TO CREATE MAGNETIC PRESSURE ON SAID WORK PIECE.
