Abstract
An electrode comprises an outer tube containing a spiral inner electrode which surrounds a rod held at its ends by fittings in the ends of the tube.
Claims14
An electrode for use in an electrochemical treatment process, the electrode comprising:
- (i) an elongate generally tubular electrode body made of relatively brittle material, said body having an interior having an inner surface and an axis extending through the interior of the electrode body;
- (ii) an elongate support member parallel to said axis within said interior of the electrode body;
- (iii) spacer means coupled between the elongate support member and the electrode body for locating radial and axial positions of the electrode body relative to the elongate support member, the spacer means comprising resilient portions engaged with the electrode body for resiliently maintaining radial spacing between the electrode body and the elongate member;
- (iv) electrical conductor means in the interior of the electrode body for making electrical contact with the inner surface of the electrode body at a plurality of positions spaced along said axis.

An electrode for use in an electrochemical treatment process, the electrode comprising:
- (i) an elongate generally tubular electrode body having a longitudinal axis and an inner surface and made of relatively brittle electrically conductive ceramic material;
- (ii) two end fittings made of plastics material and having respective plug portions extending into respective ends of the tubular electrode body arid having respective shoulder portions in axial engagement with the ends of the electrode body;
- (iii) an elongate support rod extending through the electrode body and coupled to said two end fittings;
- (iv) locating means at respective ends of the elongate support rod and operable to fix axial positions of the end fittings relative to the elongate support rod and avoid stress applied axially to the electrode body;
- (v) resilient support means connected between said plug portions and the inner surface of the tubular electrode body for supporting the electrode body radially and maintaining radial spacing between the end fittings and the electrode body while avoiding radial stress on the electrode body;
- (vi) an elongate electrically conductive member coiled around the elongate support rod between the elongate support rod and the electrode body and in electrical contact with the inner surface of the electrode body at a plurality of positions along said axis.
