Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
114 words
In a process of treating a filament of steel having a brass coating thereon with a reagent reactive with the brass and/or any exposed surface of the steel filament, the improvement characterized by (A) continuously passing a steel filament having a microscopically porous brass coating thereon through the vapors of molten benzotriazole and (B) subjecting the treated filament to a water vapor treatment; wherein said benzotriazole vapor is heated to a temperature of up to about 180° C., to form primarily a monomolecular coating on said filament so as to promote both corrosion resistance to said filament and aged adhesion between a cord thereof of such stranded filaments and adjacent, adherent sulfur vulcanized rubber.
Claim 2
Dependent Claim
114 words
In a process of treating a filament of steel having a brass coating thereon with a reagent reactive with the brass and/or any exposed surface of the steel filament, the improvement characterized by (A) continuously passing a steel filament having a microscopically porous brass coating thereon through the vapors of molten benzotriazole and (B) subjecting the treated filament to a water vapor treatment; wherein said benzotriazole vapor is heated to a temperature of up to about 180° C., to form primarily a monomolecular coating on said filament so as to promote both corrosion resistance to said filament and aged adhesion between a cord thereof of such stranded filaments and adjacent, adherent sulfur vulcanized rubber.
Claim 3
Dependent Claim
117 words
In a process of treating a stranded cord comprised of filaments of steel having a brass coating thereon with a reagent reactive with the brass and/or exposed surface of the steel filaments, the improvement characterized by (A) continually passing a cord of stranded steel filaments having a microscopically porous brass coating thereon through the vapors of molten benzothiazole and (B) subjecting the treated stranded cord to a water vapor treatment; wherein said benzotriazole vapor is heated to a temperature of up to about 180° C., to form primarily a monomolecular coating on the filaments of said cord so as to promote both corrosion resistance thereto and aged adhesion between said cord and an adherent sulfur vulcanized rubber.
Claim 4
Dependent Claim
117 words
