Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
121 words
THE METHOD OF MAKING A TAPERED WIRE BY MEANS OF A PLURALITY OF ELECTROLYTIC CELLS ARRANGED IN A ROW, SAID WIRE INCLUDING TWO SECTIONS EACH EQUAL IN LENGTH TO THE LENGTH OF SAID ROW, WHICH CONSISTS IN INSERTING THE FIRST OF SAID SECTIONS IN SAID CELLS, PASSING CURRENT THROUGH SAID CELLS WITH SAID WIRE FUNCTIONING AS THE ANODE, PULLING SAID FIRST SECTION AXIALLY OUT OF SAID CELLS AND THE SECOND SECTION AXIALLY INTO SAID CELLS AT CONSTANT SPEED, THEREBY TAPERING SAID FIRST SECTION, AND PULLING SAID SECOND SECTION AXIALLY OUT OF SAID CELLS AT A PREDETERMINED SLOWER CONSTANT SPEED SUCH THAT A TAPER IS PRODUCED ON THE SECOND SECTION HAVING THE SAME SLOPE AS THE TAPER PRODUCED ON THE FIRST SECTION.

Claim 3
Dependent Claim
113 words
APPARATUS FOR THE TAPERING OF A MOVING CONDUCTOR BY ANODIC REDUCTION, SAID APPARATUS COMPRISING, IN THE DIRECTION OF CONDUCTOR MOVEMENT, A COMPARTMENT CONTAINING AN ELECTROLYTE, A COMPARTMENT CONTAINING WASH WATER, AND A COMPARTMENT CONTAINING MERCURY, SAID COMPARTMENTS HAVING SLOTTED WALLS TO PERMIT SAID CONDUCTOR TO BE PULLED THROUGH ON A STRAIGHT LINE, TWO COMPARTMENTS LOCATED BELOW SAID STRAIGHT LINE AND BETWEEN SAID ELECTROLYTE COMPARTMENT AND SAID WASH WATER COMPARTMENT FOR RECEIVING ELECTROLYTE AND WATER, RESPECTIVELY, WHICH LEAKS THROUGH THE SLOTS IN THE WALLS OF THE ELECTROLYTE AND WASH WATER COMPARTMENTS, A CATHODE IMMERSED IN SAID ELECTROLYTE, AND A METALLIC MEMBER IN SAID MERCURY COMPARTMENT ELECTRICALLY CONNECTED TO SAD CONDUCTOR BY THE MERCURY THEREIN.
