An improved anode and base assembly for diaphragm type electrolytic cells is disclosed. In the present embodiment, downwardly facing annular portions at the base of the anode risers of dimensionally stable anodes of the type well-known in the art are welded from below directly to a metal cell base cover which seals the electrolyte contained within the cell from the cell base which is generally of copper or aluminum, thereby eliminating corrosion problems associated with leaks in the rubber gaskets or blankets formally used between the anode risers and the cell base.

Anode and base assembly for electrolytic cells

A new and improved swimming pool chlorinator which facilitates the provision of a higher strength hypochlorite solution over a wide concentration range than can be obtained from prior swimming pool chlorinators. The new and improved chlorinator utilizes a membrane type cell having opposed catholyte and anolyte chambers including a cathode and an anode member, respectively, disposed in a close spaced relationship to each other and separated by a substantially hydraulically impermable cation exchange membrane. The products of electrolysis in the catholyte and anolyte chambers are combined exteriorally of the cell to obtain sodium hypochlorite which may then be conveyed to the swimming pool water. Means are provided to selectively vary the electrical current in the cell to control the amount of sodium hydrochlorite ultimately produced.
