Title: Improvements in or relating to the production of artificial fibres, filaments, and yarns
Inventor: JONES EVAN ISLWYN
IPC: D01F6/18
Filed: 1952-09-15
Abstract: A grafted acrylonitrile polymer is dissolved in a mixture of ethylene carbonate and water and the solution is extruded into an aqueous coagulating bath so as to form fibres, filament, or yarns, and ethylene carbonate is recovered from the used coagulating bath by freezing some or all of the liquor so that at least some of the ethylene carbonate accumulated therein separates out.  The ethylene carbonate so obtained may be used to form further quantities of spinning solution and the supernatant liquid may be returned to the coagulating bath.  Separation of ethylene carbonate from the aqueous solution may be effected by cooling to about -2.5 DEG  C. and the residual liquid may contain about 10 per cent of ethylene carbonate. The grafted polymer is obtained by polymerization of monomeric acrylonitrile with or without a minor proportion of another monomeric vinyl compound in the presence of a polymeric substance of another kind which is capable of entering into chemical combination with the acrylonitrile.  In an example, a grafted acrylonitrile polymer containing 85 per cent of acrylonitrile and 15 per cent of a partially hydrolysed polyvinyl acetate is dissolved in an aqueous solution of ethylene carbonate containing 75 per cent of ethylene carbonate.  The solution is extruded at 80 DEG  C. into an aqueous solution of ethylene carbonate of 25 per cent concentration at 75 DEG C.  The filaments so obtained are passed through the coagulating bath and then directed through a second bath consisting initially of water and maintained at 85 DEG  C.  The yarn is wound on a bobbin, washed on the bobbin, dried, and then drawn 6 times its original length. When the concentration of ethylene carbonate in the first coagulating bath has reached 40 per cent, the liquor is removed and cooled below 0 DEG  C. so as to cause flakes of ethylene carbonate to be deposited.  The mother-liquor is decanted off and returned p  to the coagulating bath.  The flakes still wet with mother-liquor are added to the solvent and used for making more spinning solution.  Liquid in the coagulating bath may be caused to flow slowly towards the spinneret so that the more concentrated ethylene carbonate solution may eventually be withdrawn from the spinneret end of the bath and passed through a freezing chamber. The ethylene carbonate which separates can then be removed and used for making spinning solution, and the supernatant liquid may be passed back to the end of the bath from which the yarn emerges. Specifications 715,914 and 718,137 are referred to.

Title: Improvements in photographic reliefs
IPC: G03C7/25
Filed: 1932-08-18
Abstract: 392,785. Photographic reliefs. TECHNICOLOR MOTION PICTURE CORPORATION, 110, Brookline Avenue, Boston, U.S.A.-(Assignees of Troland, L. T. and Eaton, R. D. ; 110, Brookline Avenue, Boston, U.S.A.) Aug. 18, 1932, No. 23190. Convention date, Sept. 4, 1931. Drawings to Specification. [Class 98 (ii).] A photographic gelatine relief, particularly for imbibition printing, comprises substantially interconnected image-forming elements of dyeabsorbing gelatine embedded in a body of relatively non-dye-absorbing gelatine having approximately the same thickness at any point of the relief, the surface of the relief being substantially smooth. Such a relief is obtained by developing a silver halide emulsion with a hardening developer, e.g. pyrogallol or pyrocatechin, without reducer, and then subjecting it to a controlled oxidation treatment to oxidize the unexhausted developer in such a manner as to produce a body of non-dye-absorbing but relatively soluble gelatine filling the spaces between the particles of developer-hardened gelatine. Oxidation may be effected by vigorous washing in water containing dissolved air, or by oxidizing agents such as potassium bichromate or ferricyanide ; oxidation being controlled by regulation of the length and pH of the oxidizing wash, the concentration and pH of the bichromate or ferricyanide, and the pH of the developer. In an example, an exposed film is treated in a continuous developing machine for 3¢ minutes at 64 F. in a developer comprising 0-8 per cent pyrogallol, 0-3 per cent sodium hydroxide, 0-15 per cent ammonium chloride, 0.15 per cent potassium bromide, and 0-02 per cent citric acid. After development, the film is passed to a wash tank through which water is circulated so as to be changed completely in about 10 minutes, the water entering at 64 F. with a pH of 6-5. The film is treated for 2 minutes and is next treated for 1¢ minutes in a bath of ferricyanide of 14 per cent strength, kept at a pH of 3-7 and a temperature of 65 F., which oxdizes any remaining developer and bleaches the silver image. After a further wash for 1¢ minutes in water at 65 F. and with a pH of 6-5, the film is fixed by treatment in a non-acidic sodium thiosulphate solution of normal strength and then etched by water at 130 F.
