Claim 1
Independent Claim
120 words
A METHOD OF FORMING A COMPOSITE CONDUCTOR COMPRISING THE ORDERED STEPS OF GROUPING TOGETHER A PLURALITY OF WIRES INTO A STRAND HAVING SUBSTANTIALLY A UNIFORM DIAMETER, APPLYING SAID STRAND THROUGH A DIE HAVING A THROAT DIAMETER SMALLER THAN THE DIAMETER OF SAID STRAND AND THROAT WALLS WORKING AND MILKING BACK INCREMENTAL DIFFERENCES IN THE LENGTHS OF SAID STRAND WIRES, ADVANCING A TAPE ADJACENT SAID STRAND AT A SLOWER SPEED THAN THE APPLICATION SPEED OF SAID STRAND TO SAID DIE, FOLDING SAID TAPE LOOSELY OVER SAID STRAND TO FORM A SHEATH, SECURING ABUTTING EDGES OF SAID TAPE TO FORM A SEAL, AND APPLYING SAID SHEATH STRAND THROUGH ANOTHER DIE HAVING THROAT WALLS WORKING SAID SHEATH INTO THE INTERSTICES OF SAID STRAND.
Claim 2
