Patent GB-817007-A (GB)
Abstract: 817,007. Fixed resistors. ROSENTHAL. ISOLATOREN G.m.b.H. Nov. 22, 1955 [Feb. 16, 1955; June 28, 1955], No. 33497/55. Class 37. A heat-resistant insulated and protected wire-wound resistor is produced in which the wire is covered with a high melting-point material and in which at least two protective covers which are resistant to high temperature surround the wire, the material covering which is fused so that it connects together the protective covers and surrounds the wire so that it is embedded in an integral mass of protective material. Prismatic or cylindrical supports of glazing powder with or without a binding agent may be first pressed and then annealed or preannealed or sintered connection elements with flat pieces are fitted on which the winding is terminated by welding or hard-soldering. Cupshaped lamellµ or sleeves are pressed from the same glazing composition, the main winding support is placed between the sleeves and the unit is then annealed. The glazing is melted and fills all of the spaces between the sleeves so that the edges of the sleeves are fused together and the resistance wire is closely embedded and protected on all sides. As shown in Fig. 1, the resistance wire 2 may be wound around the plate 1 which is made of glazing powder, slots are provided in it to house the connecting-wires 5. The wound plate is then placed between flat or cup-shaped portions 6, 7, Fig. 2, and the whole then annealed. In a modification the resistance wire is wound in cavities in a supporting plate. When a low ohmic value resistance is required the wire may be bent into a zig-zag shape, Fig. 5 (not shown). Instead of a glazing substance glass or ceramic may be used.
