Title: Apparatus for the manufacture of artificial threads by the wet-spinning method
IPC: D01D5/06
Filed: 1959-04-06
Abstract: <PICT:0864765/IV (a)/1> <PICT:0864765/IV (a)/2> In wet-spinning apparatus of the type in which the filaments travel from a spinneret to a thread guide through a spinning tube open at both ends and completely submerged in a coagulating bath, the centre of the spinneret face, the axis of the tube and the point of contact of the filaments with the thread guide being in alignment, the portion of the spinneret holder adjoining the spinneret face is substantially hemispherical in external shape, the inlet of the spinning tube is provided with a cup-shaped mouth into which the spinneret holder extends, and the inner surface of this mouth is hemispherical in shape.  This hemisphere has a diameter greater than that of the substantially hemispherical portion of the spinneret holder, and the centre of the latter lies between the centre of the hemispherical interior of the tube mouth and the plane of the junction of this mouth with the inlet end of the tube.  The substantially hemispherical portion of the spinneret holder is spaced from the tube mouth inner surface to leave a clearance through which coagulating liquid can flow into the tube.  The distance between the centres of the two hemisspherical surfaces is preferably equal to 1/8 to 1/7 of the radius of the inner surface of the cup, and the ratio between the radius of the hemispherical surface of the spinneret holder and that of the inner surface of the cup is preferably about 5 : 8.  As shown in Fig. 2, the cup-shaped mouth 8 of the inlet end 5 of a spinning tube has a hemispherical inner surface 9 and into the mouth 8 extends the hemispherical surface 19 of the cap nut 18 of the spinneret holder 10.  The cap nut 18 embraces the spinneret 17 and is so far screwed on the externally screw-threaded sleeve 13 surrounding the spinning solution feed pipe 11 that rubber rings 14, 15 and filter cloth 16 are compressed to give a liquid-tight seal between the cap nut and the flange 12 of the pipe 11.  The centre of the spherical surface 19 of the cap nut 18 lies between the centre of the spherical surface 9 and the plane of the junction of the tube 5 with the mouth 8. As a result, the distance between the spherical surfaces 9 and 19 decreases in the direction of the tube 5, and turbulence of the coagulating liquid in the space in front of the spinneret 17 is reduced.  To fix the correct mutual distance between the spinneret 17 and the junction of the tube 5 with the mouth 8, four spokes 20 (Figs. 2 and 3) are provided on the cap nut 18, the free ends of the spokes co-operating with slots 21, 22, 23 inside the mouth 8. Specifications 655,516 and 784,896 are referred to.

Title: Improvements in or relating to the distillation of methylamine mixtures
Filed: 1934-04-19
Abstract: Pure trimethylamine or dimethylamine is isolated from mixtures containing mono-, di-, and tri-methylamines by distilling the mixture without added ammonia at elevated pressure until a portion of one of the amines is isolated.  The effect of the pressure is to cause the mixture to distil in two fractions one consisting of pure di- or tri-methylamine according to the pressure used while the other portion comprises an azeotropic mixture of the amines. After one of the amines has been isolated the pressure is lowered and the other amine distilled off.  The range for the higher pressure distillation lies between 75 and 250 lbs. per sq. inch and for the lower pressure distillation between 15 and 25 lbs. per sq. inch absolute pressure. Specification 355,867 is referred to.ALSO:<PICT:0436874/III/1> Pure trimethylamine or dimethylamine is isolated from mixtures containing mono-, di-, and tri-methylamines by distilling the mixture without added ammonia at elevated pressure until a portion of one of the amines is isolated.  The effect of the pressure is to cause the mixture to distil in two fractions one consisting of pure dimethyl or trimethylamine according to the pressure used while the other portion comprises an azeotropic mixture of the amines.  After one of the amines has been isolated the pressure is lowered and the other amine distilled off.  The range for the higher pressure distillation lies between 75 and 250lbs. per sq. inch and for the lower pressure distillation between 15 and 25lbs. per sq. inch absolute pressure.  A column 1, 40ft. high and packed with carborundum is mounted on a still 3 heated electrically and the distillation pressure is controlled automatically by regulating the flow of cooling water through a condenser 6 by means of a manometer 7 one end of which opens into the still and the other end forms a contact with an electrical circuit 8 operating a motor driven valve 9 controlling the flow of water to the condenser 6.  Liquid ammonia is used as cooling medium in the low pressure phase.  16 kilograms of stock obtained in the manufacture of methylamine as described in Specification 355,867 was charged into the still and refluxed under a pressure of 105lbs. per sq.inch for an hour.  After venting any ammonia, 2,4 kgs. monomethylamine were distilled off at 50,8 DEG  C. and collected in a receiver 12.  The temperature was then increased to 68 DEG  C. and a mixture of the amines distilled off leaving pure trimethylamine in the still.  The mixture was redistilled at atmospheric pressure and between 6,8 and 6,9 DEG  C. a distillate comprising 99 per cent dimethylamine was obtained.
