Patent GB-464356-A (GB)
Title: Improvements in or relating to the manufacture of plastic materials derived from mercaptans and mercaptides
IPC: C08G75/14
Filed: 1935-11-12
Abstract: Plastic material is prepared by treating an aliphatic compound, comprising at least two terminally situated mercaptan or mercaptide groups, in an alkaline solution with an oxidizing agent.  In examples, the mercaptan is treated with a sufficient amount of an alkaline hydroxide to form the mercaptide, a dispersing agent, e.g. gelatinous magnesium hydroxide, is added, and the mixture is oxidized by the addition of chlorine or bromine water, or by a blast of air. The product may be purified by washing and the polymer may be coagulated by acidification.  The plastic may be compounded with carbon black, clay, or metallic oxides, may be combined with sulphur by heating, preferably in the presence of a metallic oxide, and undergoes a change similar to the vulcanization of rubber when heated with zinc oxide. Specified mercaptans used are dimercapto-ethyl ether, b  - mercapto - ethoxy - mercapto - ethyl ether, ethylene p dimercaptan, and di-, tetra-, and hexa-methylene dimercaptans, mixtures thereof, such as a mixture of ethylene dimercaptan and dimercapto-ethyl ether, and a mixture of dimercapto - ethyl ether and dimercapto-ethylthio ether.  Specification 26928/10, [Class 2 (iii)], is referred to.  b  - mercapto - ethoxy - mercapto - ethyl ether is derived from b -chloroethoxychloroethyl ether and sodium hydrosulphide.  Tri-, tetra- and hexamethylene dimercaptans are prepared by treating the corresponding dihalogen compound with a metallic hydrosulphide or by treating the corresponding glycol with phosphorus pentasulphide.  The Specification as open to inspection under Sect. 91 comprises also the use of an alkaline polysulphide, preferably the tetra- or pentasulphide, instead of the oxidizing agent, and describes the production of plastic materials from aromatic compounds (other than thiohydroquinone) having at least two mercaptan or mercaptide groups in the p-position, e.g. p-xylylene mercaptan (which may be made by the interaction of p-xylylene dichloride and sodium hydrosulphide).  This forms the subject-matter of Specification 465,786 and does not appear in the Specification as accepted.

Abstract: 534,914. Making wire resistances. VEREINIGTE GLUHLAMPEN UND ELEKTRIZITATS AKT.-GES. Dec. 1, 1939, No. 31306. Convention date, Dec. 1, 1938. [Classes 83 (ii) and 83 (iv)] [Also in Group XXXVI] Cores and fillings ; drawing.-In the manufacture of iron-hydrogen resistances the iron wire is coated with nickel before it is coiled, to resist oxidation and the tendency to adhere to the copper core on which it is subsequently coiled. The nickel-coated wire of low-carbon iron, such as flower wire with less than 0.2 per cent. of carbon, is drawn down through die nozzles to the required cross-section, during which operation it is lubricated with an aqueous suspension of colloidal graphite. The wire is then wound on a metal (preferably copper) core, the pitch of the helix being about 3 per cent. less than is intended for the finished coils. Spaces may be provided at intervals so as to form separate coils. The core wire is then elongated by about 2 to 3 per cent whereby the core wire is straightened so that, after having been cut to the required length, the coils may be easily removed from the core. The coils are then annealed for five minutes in quartz tubes at 800‹C. in an inert atmosphere and are mounted in a frame and sealed into a bulb. This is then exhausted and filled with hydrogen under a low pressure which, however, exceeds by several mm. of mercury that which would be necessary when using a pure iron wire resistance.
