Abstract
Abstract An assembly for use in electrolysis cells including a permanent, rigid, inert and reusable base which has the form of a square open tank with only three sidewalls; and, an anodic aggregate set down on this base without an fastening means. This aggregate is composed of graphite anodic plates, anodic bars and the fourth sidewall of the base. All metallic parts of the assembly are protected by a covering which also embodies the fourth sidewall. The tightness between the fourth sidewall and the base is insured by a flexible seal.
