Filed: 1973-03-12
Abstract: 1431908 Production of MgO and HCl CHEMIEANLAGENBAU - UND MONTAGEKOMBINAT LEIPZIG VEB 12 March 1973 11800/73  Heading C1A MgO and HCl are produced by thermal decomposition of hydrated or anhydrous MgCl 2  in the presence of gases produced by simultaneous or previous combustion of H 2  with O 2  and/or Cl 2 . When anhydrous MgCl 2  is used the H 2  must be combusted in O 2  or in O 2  + Cl 2 . The MgCl 2  may be freed from inert gases by evacuation or by washing with pure O 2  or possibly H 2  and may be pre-heated and possibly dehydrated using the gases produced by the reaction. The H 2 , O 2  and/or Cl 2  may be pre-heated by heat exchange with the gases produced. The H 2  may be in the form of plasma. Sintered MgO may be produced by feeding the MgCl 2  downwardly counter current to the upward flowing gas. The product gases may be dried with MgCl 2  solution (any MgO in the gas being absorbed as MgCl 2 ) and the solution may be used to produce the MgCl 2 .H 2 O for the thermal decomposition. The MgO produced is cooled and washed with the H 2 , O 2  or Cl 2 .

Title: Improvements in and relating to the acceleration of the vulcanisation of natural andartificial varieties of rubber
IPC: C08K5/00
Filed: 1931-04-23
Abstract: 379,683. Vulcanization accelerators. CARPMAEL, A., 24, Southampton Buildings, London.-(1. G. Farbenindustrie Akt.- Ges. ; Frankfort-on-Main, Germany.) April 23, 1931, No. 12083. [Class 70.] The acceleration of the vulcanization of natural and artificial rubber is effected by the application of products obtainable by replacing at least one hydrogen atom attached to nitrogen in aliphatic-, aliphatic-aromaric, hydroaromatic or heterocyclic bases, guanidines or beguanides, by the residue RS- of an aryl compound RSH which does not exert an accelerating action. The accelerators thus produced contain the grouping =N-S-C=, and possess a favourable critical temperature, particularly when used in conjunction with other accelerators. They may be obtained by the action of N-halogen compounds of aliphatic-, aliphatic-aromatic, hydroaromatic- and heterocyclic bases, guanidines or biguanides on aromatic compounds RSH which do not exert an accelerating action ; thus N-chlorpiperidine is reacted with p-thiocresol sodium salt to give p-thiocresol-piperidine. Alternatively a suitable amino base is reacted with an aromatic sulphur halide derived from a compound RSH which does not accelerate.; thus dibutylamine is reacted with p-nitrophenylsulphur chloride in benzene to give p-nitrothiophenol-dibutylamide, and diphenylguanidine is reacted with p-nitrophenyl sulphur chloride in acetic ether to give a thioamide derivative. In examples (1) details are given illustrating the accelerating properties of the reaction products from p-nitrophenyl sulphur chloride and dibutylamine, piperidine, s-diphenylguanidine and o-tolylbiguanide in a rubber mix containing stearic acid, and also of the reaction product of chloropiperidine and p-thiocresol ; (2) details are given showing the accelerating properties of p-nitrothiophenol-dimethylamide, p-nitrothiophenol-ethylcyclohexylamide, p-nitrothiophenol-dibenzylamide, used in conjunction with dibenzthiozyl-2-2<1>-disulphide, p-nitrothiophenol-dicyclohexylamide used in conjunction with dibenzthiozyl-2-2-disulphide, p-nitrothiophenol-pentamethyleneamide used in conjunction with dibenzthiazyl-2-2<1>-disulphide, and also in conjunction with mercaptobenzthiazole. Similar results are obtained by using the reaction products of piperidine and o-nitrophenylsulphur chloride, and of piperidine and phenylsulphur chloride-o-carboxylic acid. Artificial rubber masses derived from butadiene hydrocarbons may similarly be vulcanized.

[Also in Group XI] Tubular fabrics are set by a process comprising the steps of continuously drawing the fabric over a stretcher shaped to the desired final dimensions of the fabric, the fabric being first heated and then cooled during its passage over the stretcher. As shown in Fig. 1, the fabric 7 is drawn on to a rectangular sheetmetal stretcher plate 1 by grooved rollers 3 cooperating with a frame 9 comprising the lower end of the stretcher, is heated by resistance elements 5 within a reflector box 6, and is allowed to cool before being drawn off the stretcher by rollers 4 and fed to a reciprocating folding device 12. The stretcher in the embodiment illustrated in Fig. 3 comprises a central cylindrical portion 16 surrounded by circular resistance elements within a cylindrical reflector box 6, together with upper and lower portions 17 and 18 which gradually taper to form extended straight edges 20 and 19, respectively. The stretcher of each embodiment is such that its circumference at every point along its length equals the desired peripheral length of the set fabric, and in each case provision is made for varying the size of the reflector box 6 to accommodate stretchers of varying sizes.

Abstract: 289,412. Imray, O. Y., (Elektrizitõtswerk Lonza). April 26, 1928. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 27, 1928]. Nitrogen oxides are absorbed from gaseous mixtures such as those obtained by the oxidation of nitrogen or ammonia by treatment in stages with nitric acid of increasing concentration at temperatures below 0 C. and preferably at -20 C. to -30 C. In the first stages the lower oxides of nitrogen decompose the nitric acid to form nitrogen peroxide which is absorbed in concentrated nitric acid in the final stage. The liquid from the first stages may be reconverted into nitric acid by treatment with oxygen, and that from the final stage may be separated by fractional distillation into concentrated nitric acid and pure nitrogen peroxide. Nitric acid vapours in the effluent from the final stage may be absorbed to produce solid nitrates or may be absorbed in water to produce dilute nitric acid. The treatment of the gases with nitric acid may be effected in centrifugal washers.
