Title: Improvements in and relating to the production of polyacrylonitrile films, threads, filaments, fibres and the like
Inventor: FURNESS VERA ISABELLA
IPC: D01F6/18
Filed: 1954-08-12
Abstract: Polyacrylonitrile threads of improved dyeing properties are produced by extruding a polyacrylonitrile solution containing a dyeable additive into a coagulating bath to form a thread and treating the thread, before it is dried and while it is in a wet swollen state, with a solution of a protein.  Polyacrylonitrile films may be similarly produced, the solution being extruded into or cast in the coagulating bath.  The term "polyacrylonitrile" includes copolymers containing a predominating proportion of acrylonitrile.  A "dyeable additive" is defined as a substance capable of combining with an acid dyestuff; it is added in minor proportion to the polyacrylonitrile solution so that it becomes incorporated in the threads or films as an integral part thereof. The protein solution may be aqueous, aqueousalcoholic or alcoholic and the protein may be gelatine, zein, lactic or vegetable casein or egg albumen.  Preferred dyeable additives are the resinous condensation products obtained by condensing epichlorhydrin with a primary or a di-secondary amine such as butylamine, isopropylamine or piperazine (see Group IV (b)).  In an example, a solution of 15 parts of a 94/6 mol. per cent acrylonitrile-methyl acrylate polymer, 0.6 part of a piperazine-epichlorhydrin condensation product, 38 parts of sodium thiocyanate, 23.5 parts of methanol and 23.5 parts of water is extruded into a coagulating bath at 20 DEG  C. consisting of 4 parts of water and 1 part of the sodium thiocyanate-methanol-water mixture used as the solvent in the spinning solution.  The resultant threads are withdrawn from the bath, washed with hot water, stretched to 7 times their original length in steam at 100 DEG  C. and then immersed in a 0.2 per cent solution of gelatine in water at room temperature for 1 hour.  Excess gelatine solution is removed by squeezing and the threads are dried in air at 35 DEG  C. In another example, 15 gm. of the acrylonitrile-methyl acrylate and 0.6 gm. of an isopropyl amineepichlorhydrin reaction product are dissolved in sufficient dimethylformamide to give a total volume of 100 c.c. and a film is cast from this solution by immersing a thin layer of the solution, spread on a metal block, in ethanol at 20 DEG  C.  The wet, swollen film is allowed to soak for 2 hours in a 0.2 per cent solution of zein in an aqueous-alcoholic solution containing 90 per cent alcohol, and then dried at 80 DEG  C.ALSO:Epichlorhydrin is condensed with a primary or a di-secondary amine, such as butylamine, isopropylamine or piperazine, to yield products useful as additions to polyacrylonitrile spinning solutions (see Group IV (a)).  Examples are given of the preparation of products from isopropylamine and piperazine.

Title: Method of manufacturing sintered metallurgical products
Inventor: BIAIS ROGER
IPC: C22C1/04
Filed: 1962-06-19
Abstract: A sintered metal product having a uniform metallographic structure is produced by treating a metal powder having a particle size up to 1 mm. (16 mesh) to form a film of a compound on the surface of each particle, which film reduces diffusion, degassing the treated powder by heating in vacuum, compacting the hot powder in vacuum and then shaping the compact by plastic deformation.  The starting powder may be Al, Mg or their alloys, or Fe, Ni, stainless steel or copper and the compound barrier film may be formed either by mixing the ingredients together, by oxidation, fluoridation or by evaporation coating.  In one example an Al alloy powder containing 0.05-4% of Fe and/or Ni is heated above 150  DEG C., cold pressed at a low pressure of 70-210 p.s.i., sealed in a container which is evacuated to 10-2 mm. Hg. and degassed at 600  DEG C.  The enclosed degassed compact is then compacted at 250-600  DEG C. at a pressure of 570-1420 p.s.i. and after removal from the enclosure is hot drawn.  Mg powder may also be oxidized by heating in air and then degassed, compacted and worked.

Filed: 1928-08-15
Abstract: 321,688. Wilson, P. Aug. 15, 1928. Magnetic instruments; photographic recorders and pick-ups. -In an electromagnetic loud - speaker, gramophone pick - up, recorder or the like, the reed is so mounted and the magnetic system is so arranged that as the armature moves towards the pole pieces' and so varies the length of the air gap, the attractive force on the reed is opposed by a restoring force set up in the magnetic system by the displaced reed. Preferably a magnetic plunger mounted in a bore in each pole piece exerts on the armature a restoring force which increases as the armature approaches the pole piece. The reed 10, Fig. 7, pivoted at 28, vibrates between pole pieces 25, which are bored to receive magnetic sliding members 14 carrying damping members 13 of rubber or felt. Fibre spacing members 17, bearing against adjusting screws 18 locate the members 14 in the bore. The reed, when displaced, moves the magnetic member 14 into the bore, and the attractive force of the pole piece on the reed is opposed by the magnetic force on the member 14 tending to move it towards the armature. A number of plungers 14a, 14b, 14<c>, Fig. 6, may be used. The gramophone pick-up, Fig. 2, has the leads from the coil 6 carried to terminals 5 mounted on an ebonite plate 4 fixed to the permanent magnet 1. Specification 307,767 is referred to.
