Title: Method of producing plates and the like from refractory metals
IPC: B21C37/02
Filed: 1923-06-15
Abstract: 221,295. Marks, E. C. R., (Deutsche Gluhfadenfabrik R. Kurtz und Dr Ing. P. Schwarzkopf Ges.). June 15, 1923. Plates and sheets; electric fittings. -Plates, strips &c. are made from bars of tungsten, molybdenum or other refractory metal by mechanical treatment which produces a greater lengthening of the bar in a transverse than in a longitudinal direction. For this purpose, the bar may be crossrolled, or hammered simultaneously over its full length by a transversely moving hammer, or passed through a series of dies having apertures of the same width as the bar-length and of decreasing depths. The bar may be strengthened by slightly stretching it in the longitudinal direction, as by transverse hammering, prior to the working to increase the lateral dimension of the bar. The method is stated to be particularly adapted for producing contact-pieces and anti-cathodes for R÷ntgen apparatus. Fig. 6 shows an anti-cathode made by cross-rolling a bar s between profiled rolls.

Title: Improvements in or relating to, and to methods of making, stiffeners for boots or shoes
IPC: A43B23/08
Filed: 1930-05-24
Abstract: 355,349. Boot &c. stiffeners. BRITISH UNITED SHOE MACHINERY CO., Ltd. Union Works, Belgrave Road, and MacDONALD, D. B., 132, Regent Road, both in Leicester. May 24, 1930, No. 16010. [Class 17 (ii).] Shoe stiffener blanks, more particularly toe puffs, comprising a fibrous base, such as swansdown or felt, impregnated with a stiffening material, such as celluloid, in a volatile solvent, are treated with another substance which reduces temporarily, at least at the surface, the solvent capacity of the solvent and removes the sticky character from the blanks to permit them to be readily handled for skiving or storage. The blanks may, after impregnation with a stiffening material, such as thick celluloid solution containing a solvent mixture of say, acetone or ether and industrial alcohol, as well as a certain amount of a solvent of relatively low volatility, such as diacetone alcohol, be passed through a water bath or otherwise treated with water or water vapour. A considerable amount of the solvent and water may be pressed out from the blanks and recovered and the blanks when so treated are limp and non-sticky. The solvent of low volatility comes into action when the huff is being lasted after the remaining water has evaporated. The blanks may be charged on one or both faces with a finely divided absorbent material, such as wood meal, either before or after the treatment. A solvent mixture of a celluloid solvent and a diluent of the usual kind employed in toe puff making, such as acetone and benzol mixture, may be used as the celluloid solvent. In this latter case, the puffs before storage may be surface dressed with a low volatility celluloid solvent diluted bv, say, acetone and benzol, and pressed to expel liquid released by the dressing. Specification 340,603 is referred to.
