Title: Improvements in the manufacture of artificial silk
IPC: D01F2/00
Filed: 1930-03-25
Abstract: In order to obtain modified elasticity and strength a filament or thread formed from cellulose or a derivative or compound is treated so as to change the nature of the outer layers while leaving an unchanged or only partially changed core, and then subjected to the action of a medium adapted to swell the core more than the outer layers and thus produce an expanding pressure which will cause the crystallites of the outer layer to be re-arranged with their long axes substantially transverse to the axis of the thread.  Stretching may be applied before, during, or after the above treatment.  Viscose may be spun into 20 per cent sulphuric acid, with or without neutral salts such as sodium sulphate, under such conditions as to leave a core of xanthate in the threads, which are subjected to the action of a base such as sodium carbonate or acetate, but not caustic alkali or ammonia.  The neutralized threads are washed and passed through a caustic alkali solution not exceeding 20 DEG  Tw. or a 1-20 per cent ammonia solution, whereby the core is caused to swell.  The threads are then carried through an acid bath and finished in the usual way. Cellulose nitrate or acetate solution may be spun into threads which are converted superficially into cellulose; this may be done by treating the nitrate with a sulphide solution of more than 10 per cent strength, or the acetate with caustic soda lye of similar strength; not more than 50 per cent of the acetate should be converted.  A solvent, partial solvent, or swelling agent is then applied, for instance an aqueous solution of acetone of more than 40 per cent strength.  Solvents soluble in water are preferred, e.g. acetone, formic, acetic, or lactic acid, or formalin.  After the treatment, the threads may be insolubilized and purified.  The Provisional Specification states that the invention is applicable to filaments of cellulose ethers or of the compounds described in Specifications 264,261, 286,331, 286,332 [all in Class 2 (ii), Cellulose &c.].  Specifications 8083/02, [Class 120, Spinning], 135,205, 166,931, 192,214, 274,521, 298,548, and 309,053, [all in Class 2 (ii), Cellulose &c.], also are referred to.

Title: A process for producing approximately pure manganese compounds from initial substances of a manganese nature
IPC: C01G45/00
Filed: 1938-03-29
Abstract: 511,877. Extracting manganese-containing substances. THORNTON, A. A. (Kohle und Eisenforschung Ges.). March 29, 1938, No. 9576. Drawings to Specification. [Class 1(iii)] In the extraction of manganese-containing substances with sulphur dioxide or gases containing it in the presence of water, the manganese is extracted in two stages, extraction being effected to the greatest possible extent in the first stage, and the solution of manganese sulphate and dithionate thus obtained being caused to react with fresh manganese-containing substances in the second stage, without adding fresh sulphur dioxide, in order to convert the previously formed dithionate into sulphate. Alternatively, only such amounts of sulphur dioxide may be added during the second stage that the temperature does not exceed 35 ‹C., there being always sufficient excess of the fresh manganese substances that part remains unreacted. The temperature during the second stage is preferably above 25‹C., and the sulphur dioxide added at this stage may be the gases escaping from the first stage. The partly reacted ore of the second stage may be subsequently extracted in a first stage. In the case of more slowly reacting ores, these are extracted.in a first stage, and the solution obtained is mixed with a more rapidly reacting ore. A quantity of the ore which is incompletely extracted in the first stage is added to the sludge partly extracted in the second stage. The process is described with reference to the use of two dissolving tanks and a washing tank. The material is stirred therein by agitators and by causing the sulphur dioxide to issue through jets. The process may also be operated by passing the manganesecontaining substances in counterstream to water and sulphur dioxide gases. The manganesecontaining substances should be disintegrated prior to extraction. The manganese sulphate obtained by evaporation of its solution is dehydrated at 300-500‹C. and then roasted at 900-1100‹C. in a weakly oxidizing or weakly reducing atmosphere, the gases leaving the furnace preferably containing no or very little free oxygen. The sulphur dioxide evolved is re-employed. Directly or indirectly-heated furnaces may be used. The material should be stirred during decomposition. Two examples of extracting a manganese ore are given. U.S.A. Specification 2,000,211 is referred to.

Abstract: 351,956. Photographic processes &c. SOC. INDEPENDANTE DE TELEGRAPHIE SANS FIL, 76, Route de Chatillon Malakoff, Seine, France. March 26, 1930, No. 9654. Convention date, March 27, 1929. [Class 98 (ii).] Toning and after treatment.-The metal forming a photographic sound record image on a combined sound and motion-picture film is converted into barium chloride which is opaque to invisible radiation and especially to infra-red radiation. The process is particularly applicable to sound records produced in superimposition with a motionpicture record over the whole width of a film. The silver image may, for example, be treated with a solution of barium chloride acidified with formic acid, the resulting barium oxide or hydrate being then converted by treatment with hydrochloric acid into barium chloride. Or the image may be converted into double chloride of silver and barium by treatment with a solution of barium chloride and hydrochloric acid or cerium sulphate, the silver chloride being then dissolved out. Or the image may be converted first into silver ferrocyanide by treatment with potassium ferricyanide, and then into barium ferrocyanide by treatment with a solution of barium chloride and sodium hyposulphite, and finally into barium chloride by treatment with a solution of potassium chloride or of ammonia acidified with hydrochloric acid. The Specification as open to inspection under Sect. 91 (3) (a) refers also to the conversion of the metal of the sound record image into an alkaline or alkaline-earth metal or a compound or derivative thereof. This subject-matter does not appear in the Specification as accepted.

Abstract: A heat exchanger for cooling hot crude gas containing aggressive components and for heating the pure gas obtained from the crude gas has a housing (1) formed by two lateral walls (2, 3) and upper and lower tubular bottoms (4, 5) . Partitions (8, 9) are linked to the lateral walls (2, 3) in order to form an inner cavity. In the upper and lower tubular bottoms (4, 5) are inserted the ends of a plurality of mutually parallel exchanger tubes (10) that extend parallel to the lateral walls. The hot crude gas flows through the exchanger tubes (10) and the pure gas flows through the housing (1) transversely to the exchanger tubes (10). The invention should ensure that the lateral walls of the heat exchangers are better protected against corrosion. For this purpose, an underpressure is applied to the cavities (6) formed between the lateral walls and the partitions, and the noxious gases of the pure gas that diffuse through the partitions into the cavities are fed by a duct into the stream of pure gas. Alternatively, an overpressure can be applied in the cavities formed between the lateral walls and the partitions.
