Abstract
Abstract An anode assembly having upstanding anode plates either clamped between metallic beams or on metallic bars between the metallic beams. The beams and the bars are covered with fluid-tight caps made of a sheet material with downwardly bent marginal edge portions disposed on longitudinal grooves on the sides of the beams and bars. These grooves extend axially of the beams and bars and are open to the sides and to the top of the individual beams and bars. The grooves of two next successive beams define a dovetail groove narrower at the top adjacent the caps and are filled with a sealing material to define sealing joints so that the assembly has a fluid-tight upper surface of the base.
