Abstract

1,031,863. Resistance heating elements. ROSEMOUNT ENGINEERING CO. Ltd. Oct. 20, 1964 [Dec. 4, 1963; Feb. 11, 1964], Nos. 47960/63 and 5738/64. Heading H5H. [Also in Divisions G1 H1 and H2] A resistance heater is made by joining end-toend at least one wire of uniform cross-section to a second wire of substantially uniform crosssection but having a different electrical property to the first wire to form a continuous conductor, putting an insulating sleeve on the conductor and drawing down an outer metal tube on to the insulating sleeve. In a specific embodiment, Fig. 1, a high-resistivity heating wire 12 is butt-jointed at its ends 16 to respective lengths of lower resistivity lead wire 13 of substantially the same cross-section. A woven insulating sleeve 14, e.g. of silica, is slipped over the wires and then an outer metal sheath 15 over the sleeve. A draw-wire may be used to facilitate sheathing. The assembly 11 is then passed through a series of dies and drawn down to give a compact device. The wires may also be joined by spigot, conical sleeve or scraf joints which may be soldered, brazed or fused. The wires may be exactly the same size or slightly different.
