Application No. 08/854,332
According to appellants, the invention is directed to a
metal anode useful in a galvanic or impressed current cathodic
protection system for a steel reinforced concrete article which
is a strip or ribbon having a plurality of louvers defining a
plane or planes at the lateral extremities of said louvers
(Brief, page 5). Illustrative independent claim 1 is reproduced
below:
1. In a galvanic or impressed current cathodic
protection system comprising a plurality of porous, metal
anodes, the improvement wherein each of said anodes
comprises a unitary, porous, metal strip comprising a
plurality of louvers formed on a first plane of said metal
strip having a largest area, said louvers having a lateral
and a long dimension, and said louvers defining a second
plane or both a second plane and a third plane at the
lateral extremities of said louvers.
