Title: Improvements in and relating to the production of artificial filaments, yarns, threads and the like from viscose
IPC: D01D5/22
Filed: 1956-05-08
Abstract: Regenerated cellulose filaments are produced by extruding viscose, to which has been added 1.0-10 per cent by weight, based on the weight of the cellulose in the viscose, of a polyethylene oxide of average molecular weight 300-10,000, preferably 1000-3000, at a sodium chloride salt point of 5-18 into an aqueous coagulating bath containing a proportion of sulphuric acid 0.8-1.5 times that of the caustic soda in the viscose and 3-20 per cent of zinc sulphate. The optimum concentration of polyethylene oxide for producing yarns of normal denier by the "hot stretch" process, as described in Specification 467,500, [Group IV], is 1 to 4 per cent, based on the weight of the cellulose. When spinning yarns and rayon staple of higher denier, higher concentrations of polyethylene oxide are desirable. The preferred salt point for good yarn properties is 6-16 and for good cord properties 8-13, the best all-round properties being obtained when the salt point is 9.5-11 and the viscose contains 7-7.5 per cent of cellulose. In an example, viscose containing 7.0 per cent of caustic soda, 7.5 per cent of cellulose, 41 per cent based on cellulose of carbon disulphide and 1.5 per cent based on cellulose, of a polyethylene oxide having an average molecular weight of 1000 is extruded at a salt figure of 10.2 and at 55 DEG C. into an aqueous coagulating bath containing 8.0 per cent of sulphuric acid, 14 per cent of sodium sulphate and 6 per cent of zinc sulphate. The yarn thus formed is stretched 87 per cent in an aqueous bath at 95 DEG C. containing 3 per cent of sulphuric acid, 0.8 per cent of sodium sulphate and 0.4 per cent of zinc sulphate, and is subsequently treated in a hot aqueous acid bath of the same constitution. Cords made from yarns produced by the process of the invention have greater fatigue life. Textile yarns similarly produced have an increased resistance to abrasion and soiling. Specifications 557,218, [Group IV], 634,868 and 786,319 also are referred to.

Title: Kanamycin a separation process
Filed: 1959-09-12
Abstract: Kanamycin is separated from a mixture comprising kanamycin A and kanamycin B by feeding the mixture to a column containing a porous, strongly basic, anion exchange resin on the hydroxyl cycle and removing the kanamycin A separate from kanamycin B from the column with an eluting solvent consisting of water or an aqueous solution of an organic solvent. It is preferred to use a purified kanamycin mixture and solutions containing 5 to 50% solids and the equivalent of 1g of kanamycin per 50 ml resin. Aqueous solutions of water-miscible organic solvents, e.g. alcohols or ketones may be used, especially 5% aqueous methanol. The fractions from which the kanamycin A is recovered are selected by reference to the measurement of (a) the resistivity of the eluate or (b) the refractive index of the eluate. The resin may be of the quaternary amine type. Specification 817,385 is referred to.

Patent ES-337881-A1 (ES)
Title: Device for the production and confinement of ionized gases
IPC: B01J19/08
Filed: 1967-03-11
Abstract: In a nuclear fusion device, an ionisable gas is injected into a plasma confinement chamber which contains both A.C. and D.C. magnetic fields. The D.C. fields are formed by both external and internal solenoids while the A.C. fields are produced by a waveguide antenna injector aligned with the chamber longitudinal axis and having cooled windows. The internal solenoids form a radial magnetic field. Highfrequency energy is transferred to the plasma through the waveguides and circular polarization antenna and ionization is effected by the cyclotron motion of the electrons. The radial velocity of the ions is converted to axial velocity by the axial magnetic field. The plasma is confined by the magnetic fields and the charged particles oscillate between the magnetic mirrors at the ends of the confinement zone to effect fusion.

Title: Cyclic adsorptive separation processes
IPC: B01D53/047
Filed: 1967-04-05
Abstract: In a cyclic vapour phase adsorption-desorption separation process using a fixed bed of solid selective adsorbent, the desorption is effected by forming a partial vacuum on the adsorption bed by directly condensing, with a quench liquid, the affluent vapours from the bed during the desorptive step. A purge step may be interposed between adsorption and desorption which is also effected by forming a partial vacuum by condensation of effluent from the purge step wherein the pressure is reduced to a level intermediate the adsorption and desorption stage pressures. The process is particularly suitable for separation of n-hydrocarbons from iso- and cyclo-hydrocarbons by application to the process of Specification 1,026,116. The selective adsorbent may be molecular seive.
