Abstract
6 0 1,6 3 0. Electric heating resistances. PYROTENAX, Ltd., and LEWIS, J. G. Sept. 27, 1945, No. 25083. [Class 39(iii)] [Also in Group XXXVI] In electric resistance elements comprising one or more conducting cores insulated from an outer conducting sheath, both the sheath and the core are harder than copper or aluminium, the sheath being at least as hard as the core, all the conductors being effectively annealed at the same temperature. The insulation is of pulverulent magnesia, either in powder or block form, and the composite work piece is reduced by drawing or swaging with intermediate and final annealing. The sheath may consist of iron, steel, an alloy of copper or nickel, or a copper-nickel alloy. The cores may consist of iron, soft steel, oxygen-free copper, or copper-manganese alloys such as " Manganin " (R.T.M.) or " Kumanal " (R.T.M.). A copper-nickel alloy may also be used, such as Constantan.
