Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
27 words
A process as claimed in claim 1 wherein the wires are passed through a layered zone of said granular conductor at each end of the electrolytic bath.
Claim 2
Dependent Claim
37 words
A process as claimed in claim 1 wherein said plurality of wires are transported at substantially parallel spaced intervals in a planar group through said bath and said at least one layered zone of the granular conductor.
Claim 3
Dependent Claim
35 words
A process as claimed in claim 3 wherein the granular conductor consists essentially of particles having a size larger than the diameter of the individual wires but smaller than the interval between adjacent parallel wires.
Claim 4
Dependent Claim
29 words
A process as claimed in claim 1 wherein said wires are transported horizontally through said granular conductor at a substantial distance below the upper surface of the layered zone.
