Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
95 words
In an anode used for electrolytic protection of metal construction from corrosion, which anode includes an anode material cast onto a supporting metal structure for suspending or securing the anode to the construction to be protected, the improvement wherein: said supporting metal structure comprises; main support means extending along one side of and beyond said anode material, and an expansible network of metal bonded to at least a portion of said one side of said anode material, and operable to hold said main support means in position while expanding and contracting with said anode material.
Claim 2
Dependent Claim
95 words
