Title: Apparatus for forming a yarn package
IPC: B65H54/80
Filed: 1963-07-17
Abstract: 1,019,096. Yarn coiling devices; yarn-treating apparatus. BANONEFT & SONS CO. July 17, 1963 [July 31,1962], No. 28357/63. Headings D1F and D1L.  A yarn package is built up by laying a series of overlapping coils of the yarn in an annular path around a central core on a base plate to form a continuous, helically advancing layer of coiled yarn which is packed between the base plate and a relatively axially movable cover plate, against suitable biasing means. The yarn is laid in substantially tensionless state and is therefore in a particularly suitable form for dyeing which may be effected as the yarn is being laid or after the package is completed. Yarn 104 is laid by means of a rotating distributor or nozzle 92 in a slowly rotating container comprising walls 29, 30, a central core tube 43 and extension thereof 49, and a bottom member 44 attached to the core tube 43. The container rotates with a central spindle 19, while the core tubes 43, 49 and bottom member44 are, in addition, slidable thereon and are loaded by counterweights 115 so that at the commencement of the yarn laying process the bottom member 44 is in a raised position adjacent a helically shaped cover plate 95. The yarn is fed to the nozzle 92 by feed rollers and by an air current supplied through tube 120 and is inserted in coil form in a gap between the leading edge of the plate 95 and trailing fingers thereof. Pins 100 serve to retain the initially-laid yarn in coil form. As the yarnlaying proceeds the package together with the core and bottom members are pressed downwardly until the bottom member 44 rests against a rotating support disc 26. At this stage yarn feed and rotation of the package are arrested. The cover plate 95 and yarn-laying head may be raised and rotated away from the package, the bracket 55 on which these items are supported being suitably mounted for this purpose on a central post 12, and a presser shoe 110 brought into position to compress the package into the height of the single wall member 29. A cover plate having a spring clip retainer is fitted during this step and the completed package may then be removed, comprising core member 43, bottom 44, outer wall 29 and the cover plate (Fig. 8 not shown). Since the core member 43 and outer wall 29 are perforated the package is in a suitable form for subsequent dyeing processes. Alternatively dye may be applied to the yarn or at least to the surface of the layer of coiled yarn as it is being laid by means of a dye applicator 130 mounted on the cover plate 95 (Fig. 4 and 10 not shown). The dye applicator comprises two compartments to which dye may be supplied by suitable supply pipes and from which it may be dispensed through perforations in the cover plate 95. The rate of supply and choice of colours for the compartments may be varied as desired.

Title: Hydrolysed interpolymers of vinyl fluoride with vinyl esters
IPC: C08F8/12
Filed: 1946-09-23
Abstract: Hydrolysed interpolymers are obtained by hydrolysing interpolymers of vinyl fluoride with a vinyl ester of an organic monocarboxylic acid free from non-benzenoid carbon-to-carbon unsaturation in which any carbon atom alpha to the carbon atom in the carboxyl group is attached to at least one but not more than three carbon atoms, wherein the mol. ratio of the vinyl fluoride to vinyl organic ester is within the range of from 1 : 30 to 1 : 6.  Specified esters are vinyl formate, acetate, propionate, butyrate, isobutyrate, stearate, benzoate, cyclohexanoate, hexadecanoate, tetradecanoate, toluate, naphthoate and chloroacetate.  Hydrolysis may be effected by cooling to 5 DEG -10 DEG  C. an aqueous dispersion of the interpolymer, mixing therewith a methanol-water solution of the theoretically required amount of caustic soda at the same temperature and heating the mixture to 80 DEG -85 DEG  C. until a clear solution is obtained. The solution is neutralised, e.g. with hydrochloric acid, filtered, the product precipitated by sodium chloride and filtered. Alternatively, the interpolymer, dissolved in a benzene-methanol mixture may be added to a refluxing methanol solution of caustic alkali, the mixture further refluxed, cooled and the precipitated product filtered.  Substantially completely hydrolyzed interpolymers are soluble in hot water and in hot mixtures of water and an alcohol of the general formula CnH2n+1 OH, where n=1, 2, 3 or 4 containing up to 25 per cent by weight of the alcohol.  On cooling, the resultant solutions form reversible gels.  These are suitable in photographic applications, as films, filaments which may be oriented by stretching, and fibres.  Interpolymers for use in the invention may be prepared by interpolymerizing one molar proportion of vinyl fluoride with from 6 to 30 molar proportions of the vinyl ester at temperatures of 70 DEG  C. or less, at pressures up to 300 lbs./sq. in. in the presence of a peroxy catalyst and in aqueous dispersions containing sodium lauryl sulphate and sodium dihydrogen phosphate.

Title: Improvements in or relating to the preparation of amides
Filed: 1954-10-04
Abstract: A process for preparing citrazinamide and the ammonium salt thereof comprises reacting a 1-4 C alkyl ester of citric acid with ammonia at an elevated temperature and under substantially anhydrous conditions in the presence of an alcohol solvent and, if desired, hydrolyzing the ammonium salt thus produced.  The mono-, di- and tri-alkyl esters formed by esterifying citric acid with an appropriate alcohol may be employed as starting materials, in particular trimethyl citrate.  The reaction is preferably conducted at 125-160 DEG  C. and under superatmospheric pressure, using a molar excess of ammonia.  The alcohol solvent preferably contains 1-5 carbon atoms, e.g. methanol. The ammonium salt of citrazinamide is hydrolysed to citrazinamide by dissolving in water and acidifying to a pH of 1 to 3.

Title: Photopolymerization of vinyl monomers by means of silver compounds as catalysts promoted by oxides
IPC: C08F2/50
Filed: 1959-08-20
Abstract: A normally liquid or normally solid vinyl monomer is polymerized by irradiating the monomer in the presence of water with radiation of a wavelength ranging from 10-1 to 10-10 cm., such as visible light, ultraviolet light, X-rays or gamma rays, using a catalytic amount of a radiationsensitive silver compound as catalyst, and promoting the catalystic activity of the silver compound with zinc oxide, zirconium dioxide, titanium dioxide or silicon dioxide, but excluding the use of a silver compound which is a very active oxidation agent. The monomer may be acrylamide, acrylonitrile, N-ethanol acryloamide, methacrylic acid, acrylic acid, calcium acrylate, methacrylamide, vinyl acetate, methyl methacrylate, methyl acrylate, ethyl acrylate, vinyl benzoate, vinyl pyrrolidone, vinyl methyl ether, vinyl butyl ether, vinyl isopropyl ether, vinyl isobutyl ether, vinyl butyrate, butadiene or mixtures of ethyl acrylate with vinyl acetate, acrylonitrile with styrene or butadiene with acrylonitrile.  The Specification contains a long list of suitable silver compounds, preferred compounds being silver nitrate, silver nitrite, silver sulphite, silver oxide, silver acetate and silver sulphamate.  The catalytic system may be made more effective by the presence of small amounts of optical sensitizing dyes such as erythrosin, rosin, pinacyanol and 1, 11-diethyl-2, 21-cyanine iodide.  There may also be present a small amount of a cross-linking agent such as N, N1-methylene-bis-acrylamide, triallyl cyanurate, divinyl benzene, divinyl ketone and diglycoldiacrylate.  Polymerization may be effected in bulk, in solvent solution or aqueous dispersion, and the process may be carried out in a continuous flow; when an organic solvent solution is employed there must be present a small quantity of water or a humectant such as ethylene glycol or glycerine.
