Patent GB-372835-A (GB)
Title: Improvements in the manufacture of artificial filaments, threads and the like
IPC: D01D5/247
Filed: 1931-02-19
Abstract: Hollow artificial silk &c. of more or less low lustre is made by the dry spinning method by applying a precipitant to the filaments at an early stage of their drying, and subsequently producing a rapid evaporation of the solvent.  The precipitant which is preferably applied to the filaments immediately on extrusion, may be employed in the form of vapour, but is preferably employed as a liquid; and it may be applied as a spray either to the filaments or to the spinning nozzle, or carried by the additional evaporative medium injected into the region of the spinning nozzles according to the methods of Specifications 325,233, [Class 2 (ii), Cellulose &c.], and 341,075, or the liquid precipitant may be applied as a film to the spinning nozzle according to the method of Specification 371,360, the spinning being carried out either downwardly or upwardly.  The necessary rapid evaporation of the solvent may be produced by means of heating devices grouped below the point of application of the precipitant, or by increasing the rate of flow of the evaporative medium at this point as by the use of the collector devices of Specifications 300,998, 304,674, and 326,232, [all in Class 2 (ii), Cellulose &c.]. The method is particularly applicable for the production of filaments &c. from solutions of cellulose acetate and other organic esters of cellulose, and of cellulose ethers.  Precipitants that may be used with acetone-soluble cellulose acetate are alcohols such as ethyl and amyl alcohols, esters such as butyl acetate and propionate, and ethers such as dipropyl ether, but it is preferred to employ liquids of very high precipitating power such as benzene, toluene, xylene and other cyclic hydrocarbons, and aliphatic hydrocarbons, for example, petroleum fractions boiling between 60 and 120 DEG  C.; the action of the precipitant is improved in some cases by the addition of water thereto or to the spinning solution, or the precipitant may be added to the spinning solution.  It is preferred to employ a precipitant which is less volatile than the solvent of the spinning solution, and in producing the rapid evaporation of the solvent to employ temperatures above its boiling-point but below the boiling-point of the precipitant.  The filaments may be improved in strength or their lustre may be modified by treatment either continuously with their manufacture or otherwise, according, for example, to the processes of Specifications 277,089, 323,790 and 336,217, [all in Class 2 (ii), Cellulose &c.], the filaments being stretched with or without the application of solvents or swelling agents which may be derived from the spinning solution or may be incorporated in the precipitant liquid.  The spinning solutions may contain substances that modify the lustre of the filaments, for example, the substances specified in Specifications 338,490, [Class 2 (ii), Cellulose &c.], 341,897, 343,949, 346,678 and 346,793. Specifications 314,404, 327,740, [both in Class 2 (ii), Cellulose &c.], 355,652, and 355,720 also are referred to.

Abstract: 248,377. Ges. fiir Linde's Eismaschinen Akt.-Ges. Feb. 24, 1926. Separating gaseous mixtures by liquefaction.- The most volatile components are separated from gas mixtures, e.g. a mixture of hydrogen and nitrogen is produced from gases containing carbon monoxide &c., by partial condensation under pressure; the compressed gas is cooled in counter current heat exchange with the separated constituents; the components less volatile than, nitrogen are partially liquefied to bring the hydrogen content approximately to that desired in the final mixture; the remaining gas is washed with liquid nitrogen under pressure so that nitrogen gas replaces carbon monoxide etc.; the gas is ex. panded in a motor after previous heating by ex. change with the unwashed gases, the cold of expansion liquefying the nitrogen used in the proÀ cess, which reheats the expanded gases to nearly their initial temperature. Gas passes by a pipe 1 through a heat exchanger 2; any liquefied portion, e.g. methane, is separated, expanded by a valve 12, and passed back through the exchanger. The remaining gas is cooled in an exchanger 4, the liquid formed being separated or passed with the gas into the lower part of a column 6 in which the gas is washed by liquid nitrogen. The gas leaving the column passes through the exchanger 4 to an expansion motor 7, where it is cooled, and through a column 8 where it cools and liquefies the nitrogen for supplying the column 6 through the valved pipe 10. Between the exchanger 4 and the expansion motor, the gas may passthrough a cooling coil in a bath of liquid from the base of the column 6. or of liquid nitrogen boiling at a regulated pressure. From the column 8, the hydrogen gas passes away through the exchanger 2. In a modification, the gas from the motor passes through the exchanger 4, and thecold gas from the colum 6 passes through the exchanger column S.

Filed: 1958-02-18
Abstract: 884,231. Material flow-indicators. BAILEY METERS & CONTROLS Ltd. Feb. 18, 1958, No. 5306/58. Class 78 (1). To distinguish between the flow and non- flow of coal down a shoot 3, a probe 1 is partinserted into the shoot as shown, being carried at its nodes by plates 5, rubber rings 7, and steel sleeve 2, from casing 4 bolted at 4b to the shoot. The mechanical vibrations caused by coal impinging on the probe are transformed by piezo-electric unit 10 into electrical vibrations which are passed through an amplifying circuit such that, when the downflow ceases, due to blockage, a relay is operated to give a warning, or to vibrate the hopper whence the coal comes so as to restart the flow. A resonance circuit is included in the electrical system so that the vibrations of the probe are amplified more than extraneous vibrations; and chokes serve to cause a time delay in the working of the relay so that temporary stoppages cause no alarm to be given.

Abstract: 752,365. Pyrotechnic igniters and compositions. MOSER, H. H. Feb. 24. 1954 [Sept. 1, 1953], No. 5469/54. Drawings to Specification. Classes 9(1) and 9(2) [Also in Groups XI and XII] A contact igniter operates by the holding of two bodies in surface contact with one another, one body being of oxidizing material and the other body being.a contact material therefor such that on surface contact between the two bodies there occurs a reaction with a relatively small generation of heat, the igniter comprising a third material which is ignitable through the surface contact of the two bodies and reacts thereby to increase the generation of heat whereby a combustible body can be ignited. Materials employed are hydrazine derivatives, particularly hydrazine salts, and hydroxylamine salts which are brought into contact with oxidizing materials such as permanganates, for example potassium or silver permanganate, iodic acid, silver difluoride, persulphuric acid and the higher oxides of silver in admixture.with semi-pyrophoric iron which acts as the third material. The materials are deposited, for example by impregnation or coating, on carrier substances such as fibrous substances, for example paper or cardboard, and/or thermoplastic synthetic substances, for example polyisobutylene or polymeric polyvinyl compounds in the form of polyvinyl ethers. The igniter may be applied to a fuse cord, wick, match, or the like for explosives, fireworks, torches, combustible materials, candles, firelighters, cigarettes, or an ignition strip of flash-light 'or a mixture of aluminium powder with an iron oxide as used for welding. In all cases at least, a part of the body to be ignited or caused to glow is coated or impregnated with a mixture of the oxidizing agents and the semi-pyrophoric iron and the ignition is effected by bringing the coated or impregnated part of the body into contact with a surface, for example the surface of a piece of cardboard, coated or impregnated with for example hydrazine salts. In an example 3.6 parts by weight of very finely pulverized potassium permanganate and 1.5 parts by weight of semi-pyrophoric iron are mixed in a mixing drum and made into a thin paste with a solution of polyvinyl acetate in benzene as an adhesive and comprising about 3 per cent of the mass.
