Abstract
Abstract A process is disclosed for manufacturing corrosion resistant cable. In the process, a corrosion resistant, organic based, alkyl silicate-zinc coating solution is applied to wire as the wire is twisted into cable. The solution dries on the wire in air, leaving an inorganic silicate-zinc coating on the wire. The cable is then coated with a plastic. The process is particularly useful for manufacturing brake cables.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
85 words
A process for manufacturing corrosion resistant wire cable comprising: completely coating every wire for comprising the cable with a corrosion resistant coating solution comprising an alkyl silicate-zinc mixture in an organic base as the wire is twisted to form the cable; allowing said coating on said wire comprising said cable to dry by allowing said organic base to evaporate and said alkyl silicate to hydrolyze and polymerize to form a film of inorganic silicate and zinc on said wire; and coating said cable with plastic.
Claim 2
Dependent Claim
85 words
A process for manufacturing corrosion resistant wire cable comprising: completely coating every wire for comprising the cable with a corrosion resistant coating solution comprising an alkyl silicate-zinc mixture in an organic base as the wire is twisted to form the cable; allowing said coating on said wire comprising said cable to dry by allowing said organic base to evaporate and said alkyl silicate to hydrolyze and polymerize to form a film of inorganic silicate and zinc on said wire; and coating said cable with plastic.
Claim 3
Dependent Claim
19 words
The process of claim 1 wherein said wire is galvanized prior to coating with said corrosion resistant coating solution.
Claim 4
Dependent Claim
27 words
The process of claim 1 wherein said wire is cleaned free of oil, grease and other similar contaminants prior to coating with said corrosion resistant coating solution.
Claim 5
Dependent Claim
25 words
The process of claim 1 wherein said coating on said wire, when dry, essentially consists of inorganic silicate and about 80% to about 90% zinc.
Claim 6
Dependent Claim
11 words

Claim 7
Dependent Claim
21 words
The process of claim 5 wherein the period of time for said drying is about 12 hours to about 72 hours.
Claim 8
Dependent Claim
29 words
The process of claim 1 wherein said drying is in an oven, vented to air, at a temperature in the range of about 250° F. to about 450° F.
Claim 9
Dependent Claim
20 words
The process of claim 7 wherein the period of time for said drying is about 3 to about 10 hours.
Claim 10
Dependent Claim
25 words
The process of claim 1 wherein said coating solution is applied to the wire at a rate that will provide even coating of the wire.
Claim 11
Dependent Claim
29 words
The process of claim 1 wherein said coating solution further comprises a fluorescent dye in an alcohol base for monitoring said coating of said wire for comprising the cable.
Claim 12
Dependent Claim
71 words
A process for manufacturing an automobile brake cable comprising: providing galvanized strands of metal wire, free of oil, grease and similar contaminants, for comprising the cable; completely coating said strands with an organic based alkyl silicate-zinc solution just as the strands are beginning to be twisted into cable; completely twisting said strands into cable; allowing said coating on said strands comprising the cable to dry; and coating said cable with plastic.
Claim 13
Dependent Claim
71 words
A process for manufacturing an automobile brake cable comprising: providing galvanized strands of metal wire, free of oil, grease and similar contaminants, for comprising the cable; completely coating said strands with an organic based alkyl silicate-zinc solution just as the strands are beginning to be twisted into cable; completely twisting said strands into cable; allowing said coating on said strands comprising the cable to dry; and coating said cable with plastic.
Claim 14
Dependent Claim
34 words
A corrosion resistant wire cable comprising wire completely coated with inorganic silicate and zinc, wherein said zinc comprised about 80% to about 90% of said coating, and further comprising an outside coating of plastic.
Claim 15
Dependent Claim
34 words
A corrosion resistant wire cable comprising wire completely coated with inorganic silicate and zinc, wherein said zinc comprised about 80% to about 90% of said coating, and further comprising an outside coating of plastic.
Claim 16
Dependent Claim
14 words
The corrosion resistant wire cable of claim 12 wherein said wire is also galvanized.
Claim 17
Dependent Claim
29 words
