Abstract

639,111. Electric heating resistances. STRONG, H. V., and EISLER, P. Feb. 2, 1943, No. 1749. [Class 39 (iii)] [Also in Groups XXXV and XXXVI] Resistances for electric heaters are made by producing a series of parallel conductive lines on a long strip of flexible insulating material the ends of which are shown at 55, 56 in Fig. 8. The conductors are joined in series by a corresponding set of conductive lines on a separate piece of insulating material 58 which is folded in half to bring the ends 55a, 56a in juxtaposition with the ends 55, 56 to which they are connected by soldering. The insulating material may be embossed, the conductors lying in the grooves, and the strip may be folded about its centre line 59 to produce a strip having double the number of lines in half the width. The lines are produced on the insulating material by covering the latter with metal foil and printing a series of parallel lines on the foil with an acid-resisting ink. The foil is then subjected to an etching process which removes the metal except at those parts not covered with ink which is then washed off. Specifications 639,178 and 639,179 are referred to.
