Filed: 1939-09-20
Abstract: 532,786. Magnesium sulphate. OCEAN SALTS (PRODUCTS). Ltd., and ADAMS, B. A. Sept. 20, 1939, No. 26251. [Class 1 (iii)] In the preparation of magnesium sulphate from magnesium hydroxide prepared from sea water or other natural waters, the magnesium ions are separated from impurities by the use of an organic base exchange material, e.g. that described in Specification 450,308. The washed magnesium hydroxide is dissolved in an acid and the solution is passed through the base exchange body, which has been previously treated with an acid. The magnesium ions are adsorbed in place of hydrogen ions. The material is then washed with water to remove chlorine ions and the magnesium is dissolved out with sulphuric acid. Free acid in the resulting solution may be neutralized with magnesium hydroxide or adsorbed by an amino resin as described in Specification 450,309. The acid displaced by the magnesium from the base exchange body may be used for dissolving further, quantities of magnesium hydroxide.

Patent GB-656286-A (GB)
Title: Improvements in or relating to the manufacture of fibres and yarns of regenerated cellulose from viscose
IPC: D01F2/06
Filed: 1948-10-13
Abstract: Regenerated cellulose fibres and yarns are obtained by extruding a normal viscose composition, to which there has been added 1-5 per cent of an organic water-soluble material consisting essentially of urea, into an aqueous acid coagulating and regenerating bath.  Normal viscose is stated to be one having a sodium hydroxide content of 6-8 per cent, based on the weight of the viscose, a cellulose content of 6-8 per cent, and a salt point of 3-6.  The fibres and yarns produced have high breaking toughness and low average stiffness (ratio of the tensile strength at break to the elongation at break).  The urea may be added immediately after the production of the viscose, or during ripening, or immediately before spinning.  The spinning bath may contain 8-12 per cent of sulphuric acid, 2-5 per cent of zinc sulphate, and 16-20 per cent of sodium sulphate, and the temperature of the bath may be 45-55 DEG  C.  In an example, 2.5 per cent of urea is added to viscose having a salt point of 3, and the solution is then spun into a bath containing sulphuric acid and zinc and sodium sulphates.  The yarn obtained is stretched by 75 per cent.  In other examples, the viscose has a salt point of 5.1-5.9.  The fibres and yarns obtained may have tensile strength of 2.7-3 grams per denier and elongation of 17-23 per cent. They may be used in making tyre cords.
