Title: Method for the purification of brine
Inventor: SUZUKI HIDETOMO
IPC: C01F5/22
Filed: 1962-01-26
Abstract: A method for the purification of brine containing magnesium and possibly also calcium ions comprises adding to the brine sodium hydroxide, or slaked lime or a combination of sodium hydroxide and sodium carbonate, thereby precipitating the magnesium ion as magnesium hydroxide and the calcium ion, if sodium carbonate is used, as calcium carbonate, dissolving air under pressure in at least part of the treated brine, releasing the pressure to allow the air to be released from the brine as small bubbles which entrain the precipitate and bring it to the surface of the brine, and separating the precipitate thus accumulated at the surface of the brine.  The treatment is preferably effected at a brine temperature of up to 100 DEG C.  Coagulating or frothing agents may be added to the brine.

Title: Improvements in or relating to dyeing fibrous materials
Inventor: HANNAY RAMSAY JOHN
IPC: D06P3/04
Filed: 1952-02-05
Abstract: Fibrous materials e.g., wool, cotton, viscose rayon, nylon and artificial protein fibres, are dyed in an aqueous bath in the presence of an organic ester which has a sufficiently high and steady rate of hydrolysis and is present in a sufficient proportion and under such conditions of temperature and initial pH value as to ensure that hydrolysis of the ester takes place and that the acid formed by the hydrolysis is at least sufficient to prevent any increase of more than 0.2 of a unit of pH in the initial pH value of the dyebath during the dyeing.  Specified organic esters are diethyltartrate, -succinate, -fumarate, -malonate and -oxalate, ethyl lactate, triethyl citrate, phenyl acetate, monoacetin, triacetin and dibutyl oxalate.  Examples describe the dyeing of wool with acid and metachrome dyes and also the dyeing of nylon and cotton.
Patent GB-628844-A (GB)
Title: "process for the manufacture of cellulose esters"
IPC: C08B3/00
Filed: 1947-02-03
Abstract: Cellulose is esterified by means of an esterifying liquid capable of dissolving the cellulose ester obtained and, after some of the cellulose ester has been formed and has passed into solution, the solution is separated from the residue of the reaction mass and treated so as to prevent appreciable degradation of the cellulose ester.  Meanwhile, in the undissolved residue, the reaction continues until esterification and solubilisation of the whole of the cellulose takes place.  The reaction in the solution is stopped by destroying the excess esterifying reagent or by neutralizing the catalyst.  In example 1 cellulose, which has been pretreated with acetic acid, acetic anhydride and, if desired, sulphuric acid, is placed in an apparatus with stirring gear and treated with acetic acid, acetic anhydride and sulphuric acid.  After 45 minutes the material is fed on to a filtering network of wire gauze and felt made from textile materials which are not attacked by the esterifying liquid.  The reaction continues in the mass left on the filter since the cellulose swells and becomes impregnated with the esterifying liquid, whilst in the esterifying bath, and this absorbed liquid is not removed by filtering.  Thus this material also goes gradually into solution. Immediately on filtering the solution is treated with aqueous acetic acid solution and then the cellulose acetate is precipitated by the addition of a large excess of water.  In example 2 cellulose is esterified to cellulose aceto-butyrate, by a method similar to that given in example 1 for cellulose acetate, and after 40 minutes the dissolved ester is separated in a centrifugal filter whilst the reaction continues in the undissolved cellulose.  The ester solution is treated with a solution of potassium acetate in acetic acid to neutralize the sulphuric acid.  In example 3 cellulose is subjected to acetylation in a continuous acetylation apparatus of the type described in Specification 274,814, [Class 2 (ii)].  The mixture on emerging is pumped into a column furnished with stacks of wire gauze of increasingly fine mesh.  The undissolved fibres are retained until they go into solution.  The solution which emerges is treated with aqueous acetic acid and ripened until it has a titre of 55 per cent combined acetic acid.  The cellulose acetate is then precipitated by the addition of a large quantity of water.  Metallic turnings, Raschig rings &c. may be used instead of wire gauze.  In example 4 a mixture prepared as in example 3 is pumped into a high speed centrifuge.  Owing to the relative densities of the fibres and the bath the fibres are thrown to the periphery so that only the solution is evacuated from an outlet in the centre.
Patent GB-664340-A (GB)
Title: Dyeing process for cellulose ester or ether textile materials
Filed: 1949-12-15
Abstract: Textile material of a cellulose organic ester or ether is coloured by applying a finely-divided unreduced vat dye and subjecting the material to the action of an aqueous reducing liquor rendered alkaline with caustic soda and containing a water-miscible organic swelling agent; the leuco vat dye is thus fixed on the material and is finally oxidized to the vat dye.  The reducing bath may contain 0.2-1.2 per cent of caustic soda, 0.2-1.2 per cent of sodium hydrosulphite and 10-50 per cent of swelling agent.  Suitable swelling agents are lower aliphatic alcohols such as methanol, isopropanol, butanol and amyl alcohol, ketones such as acetone and methyl ethyl ketone and diacetone alcohol.  A dispersing agent may be used to form an aqueous dispersion of the vat dye, e.g. sodium alkyl-naphthalene-sulphonate or a sulphated or sulphonated fatty acid amide.  Examples show the process applied to cellulose acetate.  The Specification as open to inspection under Sect. 91 is not restricted as to the nature of the alkali in the aqueous reducing liquor.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the manufacture of glass to metal seals
Inventor: BOARDMAN KENNETH WILLIAM
IPC: C25B11/08
Filed: 1959-01-30
Abstract: A metal shroud for use in the formation of a glass-to-metal seal is oxidized by exposure to dry steam.  The shroud may be formed of a metal having good corrosion-resistance e.g. nickel-iron alloy, or of a metal having poor corrosion-resistance e.g. low carbon steel, that has been coated as by electro-plating with nickel, cobalt, chromium, gold, copper, platinum, palladium or tungsten.  As described, the shroud is de-greased, chemically cleaned by heating in dry hydrogen at 500 DEG -1200 DEG C., heated in wet hydrogen at 800 DEG -1200 DEG C., if coated, to diffuse the coating metal into the base, and then heated at 500 DEG -700 DEG C. in dry steam plus air.  It is stated that after forming the seal, the oxide layer on the exposed metal parts may be easily removed (e.g. by treatment with nitric or hydrochloric acid) since it contains an amount of lower valency oxide.
