Abstract
Abstract Wire is cleaned by passing it through an electrolytic cleaner then through an ultrasonic rinse. The electrolytic cleaner comprises a graphite tube through which the wire passes, an alkaline aqueous solution between the wire and the graphite tube, and an electric current, at least half D.C., between the wire and the graphite tube.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
58 words
A method of cleaning wire comprising 1. passing said wire through a graphite tube; 2. providing an alkaline aqueous solution between said tube and said wire; 3. passing an electric current which is at least half direct current between said wire and said graphite tube with said graphite tube as the anode; and 4. ultrasonically rinsing said wire.
Claim 2
Independent Claim
58 words
A method of cleaning wire comprising 1. passing said wire through a graphite tube; 2. providing an alkaline aqueous solution between said tube and said wire; 3. passing an electric current which is at least half direct current between said wire and said graphite tube with said graphite tube as the anode; and 4. ultrasonically rinsing said wire.
Claim 3
Dependent Claim
60 words
A method according to claim 1 wherein said alkaline aqueous solution has a pH of about 9 to about 11 and is a solution of a water soluble compound selected from the group consisting of salts of a weak acid, a hydroxide, and mixtures thereof, at a concentration of about 2% up to the solubility in water of said compound.
Claim 4
Dependent Claim
32 words
A method according to claim 2 wherein said compound is about 0 to about 95% carbonate and about 5 to about 100% phosphate at a concentration of about 5 to about 40%.
Claim 5
Dependent Claim
14 words
A method according to claim 1 wherein said current is entirely a direct current.
Claim 6
Dependent Claim
18 words
A method according to claim 1 wherein said current is about 100 to about 1000 amps/ft 2 .
Claim 7
Dependent Claim
51 words
A method according to claim 1 wherein the walls of said graphite tube are at least about 1/4 inch thick, said tube is about 2 to about 10 feet long, and of sufficient inside diameter to provide a clearance between it and the wire of about 1/2 to about 1 inch.
Claim 8
Dependent Claim
27 words
A method according to claim 1 wherein said wire passes downwardly through a first vertical graphite tube, under a sheave, then upwardly through a second graphite tube.
Claim 9
Dependent Claim
15 words
A method according to claim 1 wherein said wire passes horizontally through said ultrasonic rinse.
Claim 10
Dependent Claim
22 words
A method according to claim 8 wherein in said ultrasonic rinse water moves in the direction opposite to that of said wire.
Claim 11
Dependent Claim
25 words
A method according to claim 1 wherein the frequency of said ultrasonic rinse is from above the frequency of audible sound to about 40 kilohertz.
Claim 12
Dependent Claim
32 words
A method according to claim 1 including drying said wire after it has passed through said ultrasonic rinse, and coating said wire in an electrostatic fluidized bed after it has been dried.
