Abstract An electrode assembly is provided for an electrolytic cell which comprises a substantially horizontally extending foraminate titanium structure carrying on at least a part of its surface a coating comprising an operative anode material, an array of parallel spaced rods approximately covering the area of said foraminate structure, each rod having a titanium casing which is rigidly and conductively connected along its length to the upper surface of said foraminate structure and is also attached to the titanium casing of at least one rectangular bar which passes transversely over said rods by welds which enclose in fluid-tight manner intercommunicating openings through the juxtaposed areas of the casings of said rod and said bar, the casing of each said rectangular bar having an opening in its upper face, and attached in fluid-tight manner to said upper face to enclose said opening an upstanding wall of titanium sheet, the space within said upstanding wall and the titanium casings of said bar and said rods being substantially filled by a continuous core of aluminum or an aluminum alloy, said core being bonded to the surrounding titanium surfaces by an inter diffusion layer of an alloy formed between the core metal and the surrounding titanium metal.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
53 words
An anode assembly acCording to claim 1, wherein the opening in the upper face of the casing is a rectangular opening and the upstanding current lead-in casing enclosing said opening is attached to the said upper face by a continuous weld around the periphery of the said opening to form a rectangular enclosure.
Claim 2
Dependent Claim
19 words
An anode assembly according to claim 1, wherein the foraminate titanium structure is a sheet of expanded titanium metal.
Claim 3
Dependent Claim
38 words
An anode assembly according to claim 3, wherein each of the said tubes is connected to the expanded titanium metal sheet by a series of titanium studs, each of which is welded to the tube and the sheet.
Claim 4
Dependent Claim
31 words
An anode assembly according to claim 1, wherein the foraminate titanium structure has been built up from longitudinally extending titanium members spaced apart with their long axes parallel to each other.
Claim 5
Dependent Claim
32 words
An anode assembly according to claim 1, wherein the anode material is a material selected from the group consisting of a platinum group metal and an oxide of a platinum group metal.
Claim 6
Dependent Claim
26 words
