Abstract
Abstract Provides an imperforate valve metal blanket between the cell base of a electrolysis cell and the cell can, which acts as a conductor from the positive current leads to dimensionally stable anodes and provides hollow anodes with perforate and imperforate sections to promote anolyte circulation within the cell.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
69 words
An anode structure for electrolysis cells comprising a planar, electrically conductive blanket to be supported on the cell base and a plurality of vertical hollow, dimensionally stable anodes electrically connected to the blanket provided with an electrocatalytic coating, the said hollow anodes being provided with a plurality of perforations from near the bottom to some distance from the top and an upper imperforate section near the open-ended top thereof.
Claim 2
Dependent Claim
69 words
An anode structure for electrolysis cells comprising a planar, electrically conductive blanket to be supported on the cell base and a plurality of vertical hollow, dimensionally stable anodes electrically connected to the blanket provided with an electrocatalytic coating, the said hollow anodes being provided with a plurality of perforations from near the bottom to some distance from the top and an upper imperforate section near the open-ended top thereof.
Claim 3
Dependent Claim
17 words
