Abstract

730,616. Electric immersion heaters. WAUGH, A. K. Feb. 11, 1954 [Feb. 19, 1953], No. 4707/53. Class 39 (3). In an immersion heater of the type comprising an outer cylindrical casing c containing coiled resistances wires a supported by removable refractory material b, the. outer casing is a solid drawn tube and has V grooves d machined in its outer surface lying adjacent to each other and extending over the whole or substantially the whole of the surface. The machined V grooves are formed as a continuous thread, as a series of adjacent annular grooves, or as parallel longitudinal grooves.
