Title: Improvements in and relating to peroxidation
IPC: C01B15/08
Filed: 1960-07-11
Abstract: Alkali, or alkaline earth, metal, or ammonium monopersulphates are prepared by reacting the corresponding bisulphate and hydrogen peroxide at 50 DEG -110 DEG C. in the presence of an oxygen-containing inorganic acid in amount to provide 0,05-2 equivalents of hydrogen ion per kg. reaction mixture.  The bisulphate may be produced in situ from sulphate and sulphuric acid, or by hydrolysis of pyrosulphate.  Acids may be sulphuric, phosphoric, nitric, or perchloric acids.  The hydrogen peroxide and bisulphate should be in molar ratio 1:1 to 5:1.  The H2O2 should be at least 65% to ensure at least 1:1 ratio H2O2:H2O in the final reaction mixture, but the reaction may be effected under conditions to produce selective water removal.  The monopersulphate may be isolated by neutralizing acid and selectively dissolving, or by selective crystallization.  Stabilizers, e.g. dipicolinic acid, oxides of tin, or tetrasodium pyrophosphate, may be added to the mixture. Examples refer to the preparation of persulphates of sodium, potassium, ammonium calcium, and magnesium.
Patent GB-917038-A (GB)
Title: Manufacture of barium hydroxide
Inventor: UNWIN JACK TRASK
IPC: C01F11/10
Filed: 1960-07-11
Abstract: Barium hydroxide is produced by initially reacting in a vessel solutions of barium zincate and barium sulphide and thereafter alternately adding to the reaction mixture quantities of zinc oxide and barium sulphide solution and terminating the process after any one of the further additions of barium sulphide, the quantity of zinc oxide added at each stage being not more than will dissolve in the solution present at that stage, the interval of time between each zinc oxide addition and the next barium sulphide solution addition being at least sufficient to permit as much as possible of the zinc oxide to substantially dissolve, and the quantities of barium sulphide solution employed initially and in each subsequent stage including or excluding the terminating stage, being not more than the stoichiometric quantity required for reaction.  The initial reaction can be conducted either by adding the two solutions simultaneously to the reaction vessel or by forming the barium zincate solution in situ in the reaction vessel and then adding the barium sulphide solution. Preferably at the end-point of the precipitation reaction a slight excess of barium sulphide is added.  Before crystallization of the barium hydroxide but after separation of the precipitated zinc sulphide, the solution is treated with hydrogen peroxide at elevated temperature to eliminate the oxidizable sulphur.  The zinc sulphide separated is washed either with water or preferably with a dilute barium hydroxide solution, e.g. the sulphide may be washed with heated mother liquor obtained from the subsequent stage in which the barium hydroxide is crystallized.  The washed zinc sulphide which still contains 14% of barium hydroxide is calcined at 960 DEG C. to form zinc oxide, the barium impurity being converted to the sulphate. The calcined product may be dissolved in barium hydroxide solution; the zinc oxide dissolves to give more barium zincate but the barium sulphate remains in suspension. However preferably the hydroxide present with the washed uncalcined zinc sulphide is first converted to the chloride by adding 36% hydrochloric acid.  The barium chloride solution obtained may be used to slurry the zinc sulphide produced in the next cycle for treatment with hydrochloric acid.  After separation from the barium chloride solution, the zinc sulphide is washed with water and then calcined to produce zinc oxide as before. Instead of treating the washed zinc sulphide with hydrochloric acid, sulphuric acid may be used to produce a 70% lithopone, ZnS.BaSO4.  In this case the calcination temperature is 700 DEG  to 725 DEG C.

Title: Surface coating resin compositions
Inventor: MASSEY DEREK JAMES ROWLAND
IPC: C08L67/06
Filed: 1962-06-23
Abstract: A surface coating composition comprises an unsaturated polyester resin and a modified phenolic resin, the latter resin containing the units <FORM:0992345/C3/1> where R-O represents a phenolic residue forming part of a novolac resin molecule, said novolac resin being formed by condensing 1 mole of phenol with less than 1 mole of an aldehyde under conditions which give a thermoplastic soluble product; X represents a substituted or unsubstituted saturated aliphatic hydrocarbon group; Y represents an alkylene group having b -g -unsaturation with respect to the ether atom and n is the number of repeating units in the modified phenolic resin molecule. The terms "unsaturated polyester resin" and "modified phenolic resin" in both cases include the respective resin by itself and the resin together with a copolymerizable unsaturated liquid monomer.  Preferred proportions by weight of the resins are 10 to 80% of modified phenolic resin and 90 to 20% of unsaturated polyester resin.  The unsaturated polyesters are prepared by reacting polycarboxylic acids or anhydrides with polyhydric alcohols, one or more of which are ethylenically unsaturated, and they may be modified with monocarboxylic acids and monohydroxyalcohols.  In the modified phenolic resins X is preferably an aliphatic hydrocarbon group, the backbone chain of which has 3 carbon atoms and Y preferably contains 3 carbon atoms. The preferred phenolic resins are prepared either by (a) reacting under etherifying conditions a phenol novolak resin with a glycidyl ether containing an alkylene group having b -g -unsaturation or (b) preparing polyglycidyl ethers of the novolak resin with epichlorohydrin and then reacting the ethers with a b -g -ethylenically unsaturated alcohol.

Abstract: 837,951. Testing strength of hollow bodies. WHESSOE Ltd. July 17, 1958 [July 31, 1957], No. 24271/57. Class 106 (2). A body to be tested, e.g. the pressure vessel of a nuclear reactor, is filled with liquid under pressure and at the same time is immersed partly or completely in liquid. A preliminary test of the vessel is made with air supplied by a compressor 6. The vessel is then filled with water through a pipe 10, stand-pipes 24, 25 being closed after the water has overflowed from them, and a vent 26 being used to remove air from the very top of the vessel. At the same time the space between the biological shield 4 and the vessel is also filled with water through a pipe 11. By this means, the additional thrust on the supports 3 is relatively low. After being filled, pressurized water is supplied through a pipe 18, careful observation being kept on a pressure-gauge 20, on which leakage is indicated by a sudden fall in pressure. In modifications, Figs. 2 and 3 (not shown), the water in which the vessel 1 is immersed is contained in a steel tank erected within the biological shield 4.
