Abstract

671,117. Making electric heaters. BRITISH THOMSON-HOUSTON CO., Ltd. April 19, 1949 [April 30, 1948], No. 10355/49. Classes 83 (ii) and 83 (iv). [Also in Group XI] Mandrels.-A resistance heating wire is coiled helically on a mandrel comprising a rod 1 with detachable outwardly tapering parts 2 thereon, so as to give a helical coil, with end parts of greater diameter than the central part, the latter being elongated by stretching. The coil is placed in a metal tube then filled with magnesium oxide which is finally compacted by rolling, drawing or swaging to form an electric heating element (see Group XI).
