Abstract: 639,178. Electric heating resistances. STRONG, H. V. and EISLER, P. Feb. 2, 1943, Nos. 23842/48, (divided out of 639,111) and 5379/43. [Class 39 (iii)] [Also in Groups XXXV, XXXVI and XL (a)] Electric heating resistances are formed in position upon insulating supports by making an imprint on a resistant metal foil in an ink which serves as a resist and then treating the foil so as. to leave a resistant patern on an insulating support. The foil may have temporary backing, for example waxed paper, and the pattern then printed on the foil, those portions thereof which are not covered by the printed pattern being removed, as by etching. The resulting metallic pattern 51 is then transferred from the paper backing to the final insulating support 52, such as fabric, wall paper or the like. If desired an ornamental design 53 may be printed over the resistance 51 in an insulating ink, the sheet then being made the cathode in an electrolytic bath in which copper is deposited on the exposed portions of the resistance. The part of the heater within the design 53 is thus of higher resistance than the remainder. When used on fabric the material may be dyed with a dye which changes colour as the temperature rises. The conducting surface may finally be insulated by means of a layer of varnish. Specification 639,111 is referred to.
