Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
66 words
A process of treating a filament of steel which comprises continually passing a steel filament having a microscopically porous brass coating thereon through the vapor of benzotriazole to form primarily a monomolecular coating thereof on said filament where said filament is at a temperature lower than the temperature of said vapor so that the vapor is condensed on the surface of the wire while interacting therewith.
Claim 2
Dependent Claim
66 words
A process of treating a filament of steel which comprises continually passing a steel filament having a microscopically porous brass coating thereon through the vapor of benzotriazole to form primarily a monomolecular coating thereof on said filament where said filament is at a temperature lower than the temperature of said vapor so that the vapor is condensed on the surface of the wire while interacting therewith.
Claim 3
Dependent Claim
84 words
A process of treating a stranded cord which comprises continually passing a cord of stranded steel filaments, said filaments having a microscopically porous brass coating thereon, through benzotriazole vapor to form primarily a monomolecular coating thereon, through benzotriazole vapor to form primarily a monomolecular coating thereof on the filaments of said cord, where said cord is at a temperature lower than the temperature of said vapor so that the vapor is condensed on the surface of the filaments of the cord while interacting therewith.
