Title: Process for increasing the effectiveness of catalysts for the production of polymerisati on products
IPC: A61K6/00
Filed: 1955-02-28
Abstract: The process of the parent Specification for increasing the effectiveness of organic sulphur-containing polymerization catalysts in the manufacture of resinous polymers by the addition of a halogen compound containing an ionically-linked halogen atom as activator is modified by utilizing a pseudo-halide instead of, or in addition to, the halogen compound.  A pseudo-halide is a compound containing a pseudohalogen radical, i.e. a radical with physical and chemical properties very similar to those of halogens, e.g. ammonium thiocyanate, the dibutyl amine salt of thiocyanic acid, potassium cyanide, or azides.  The polymer may be made by polymerizing in bulk methyl methacrylate in the presence of polymethyl methacrylate. Sulphur-containing catalysts mentioned are sulphinic acid, toluene sulphinic acid, and di-(p-toluene-sulphone-methyl)-ethylamine.  The polymerizable mix may also contain a small amount of methanol and an extremely small amount of copper.

Title: Improvements in and relating to the manufacture of nitric acid by oxidation of ammonia
IPC: C01B21/26
Filed: 1931-02-27
Abstract: Gases escaping from the absorption columns for nitric acid produced by oxidation of ammonia under pressure are heated to such a temperature that they can be expanded in expansion machines without their condensation point being reached.  Since no acid liquor condenses, the expansion can take place in centrifugal machines made of ordinary materials, provided with outside bearings to avoid contact of the gases with lubricating oil.  The heating may be effected indirectly as with steam, or preferably directly by the combustion in the gas of a liquid or gaseous fuel. In an example, the moist gases at a pressure of 7 kilos and containing 3.5 per cent oxygen and 0,15 per cent nitrogen oxides are dried and heated under pressure to about 450 DEG  C. by atomized oil, introduced by a pump without primary air or atomizing steam. The hot combustion gases pass to a regenerating turbine.
