Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
140 words
THE METHOD OF MAKING A MULTIPLICITY OF IDENTICAL ELECTRICAL RESISTANCE ELEMENTS, WHICH METHOD COMPRISES THE SEQUENCE OF STEPS OF CONTINUOUSLY MOVING A CONTINUOUS LENGTH OF WIRE IN LENGTHWISE DIRECTION THROUGH A PLURALITY OF ZONES IN A PRODUCTION LINE, EXTRUDING ONTO THE WIRE A CONTINUOUS MASS OF RESISTANCE MATERIAL IN THE FORM OF A STRIP PROVIDED WITH SUBSTANTIALLY FLAT PARALLEL OPPOSITE SIDES WITH THE WIRE EXTENDING LENGTHWISE THERETHROUGH, TRANSVERSELY NOTCHING THE STRIP AT OPPOSITE SIDES IN A COMMON PLANE TO SUBDIVIDE THE STRIP INTO PARTIALLY CONNECTED MASSES OF IDENTICAL SHAPE AND SIZE, FIRING THE MASSES TO CAUSE THE SAME TO HARDEN AND BE ADHERED TO THE WIRE, SECURING A TRANSVERSELY EXTENDING ELECTRO-CONDUCTIVE LEAD TO BOTH SIDES OF EACH MASS, AND FINALLY SEPARATING THE ADJACENT MASSES AT THE NOTCHES AND SERVERING THE WIRE AT THE NOTCHES TO PRODUCE THE INDIVIDUAL RESISTANCE ELEMENTS.
