Abstract
An electrode comprises an outer tube (1) containing a spiral inner electrode (5) which surrounds a rod (4) held at its ends by fittings (E1, E2) in the ends of the tube.
Claims12
An electrode comprising a generally tubular body having an external surface, the tube including an elongate rod having at least one end fitting, a power supply conductor being present in the annulus between the rod and the inner surface and in contact with that surface, and in use, in connection with a power supply.
An electrode according to any preceding Claim, wherein the at least one fitting comprises a cap present at one of the ends of the body to close that end, the cap having an inner end portion shaped to hold and contribute to centralisation of the end cap within the body.
An electrode according to any preceding Claim, wherein the cap has a socket to receive the respective end of the rod.
An electrode according to any preceding Claim, including means to seal the interior of the body.
An electrode comprising a generally tubular electrode body, an elongate support member extending axially through the electrode body, spacer means between the electrode body and the support member for maintaining the inner surface of electrode body spaced from the support member, and electrical conductor means in the space between the support member and said inner surface and electrically connected to said inner surface characterised in that the electrical body (1) is made of relatively brittle material and, to support the electrode body while limiting radial and axial force applied thereto, said spacer means (E1, E2) comprises at least one spacer member engaged with a respective end of the electrode body via resilient engagement means (13) and coupled to the support member (4) by locating means (15) defining the position of the spacer member along the support member, said electrical conductor means comprising resilient connection means (5) for resiliently contacting the inner surface of the electrode body at a plurality of positions axially spaced along the electrode body.
