Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 62 words
A COMPOSITE FORMED BY VULCANISING A RUBBER ARTICLE CONTAINING STEEL REINFORCEMENT COMPRISING A STEEL CENTRAL CORE, AND AN INNER COATING OF A METALLIC MATERIAL FOR SAID CORE OF A BRASS ADAPTED TO BOND TO SAID RUBBER ARTICLE AND AN OUTER COATING OF A GROUP IV METAL OF THE PERIODIC TABLE, SAID OUTER COATING HAVING A THICKNESS FROM ABOUT 0.001 TO 0.14 MICRONS.
Claim 2
Dependent Claim 62 words
A COMPOSITE FORMED BY VULCANISING A RUBBER ARTICLE CONTAINING STEEL REINFORCEMENT COMPRISING A STEEL CENTRAL CORE, AND AN INNER COATING OF A METALLIC MATERIAL FOR SAID CORE OF A BRASS ADAPTED TO BOND TO SAID RUBBER ARTICLE AND AN OUTER COATING OF A GROUP IV METAL OF THE PERIODIC TABLE, SAID OUTER COATING HAVING A THICKNESS FROM ABOUT 0.001 TO 0.14 MICRONS.
Claim 3
Dependent Claim 76 words
A PROCESS FOR FORMING A TIRE OF A METALLIC MATERIAL AND VULCANIZED RUBBER WHICH COMPRISES CONTACTING A BRASS COATED STEEL CORE METALLIC MATERIAL AND AN UNVULCANIZED RUBBER AND UNIFYING THEM BY VULCANIZATION CHARACTERIZED IN THAT THE BRASS COATED METALLIC MATERIAL IS COATED WITH A FILM FROM ABOUT 0.001 TO 0.14 MICRONS THICK OF A MTEAL SELECTED FROM THE METALS OF GROUP IV OF THE PERIODIC TABLE PRIOR TO CONTACTING THE METALLIC MATERIAL WITH THE UNVULCANIZED RUBBER.
Claim 4
Dependent Claim 76 words
A PROCESS FOR FORMING A TIRE OF A METALLIC MATERIAL AND VULCANIZED RUBBER WHICH COMPRISES CONTACTING A BRASS COATED STEEL CORE METALLIC MATERIAL AND AN UNVULCANIZED RUBBER AND UNIFYING THEM BY VULCANIZATION CHARACTERIZED IN THAT THE BRASS COATED METALLIC MATERIAL IS COATED WITH A FILM FROM ABOUT 0.001 TO 0.14 MICRONS THICK OF A MTEAL SELECTED FROM THE METALS OF GROUP IV OF THE PERIODIC TABLE PRIOR TO CONTACTING THE METALLIC MATERIAL WITH THE UNVULCANIZED RUBBER.
