Patent GB-801246-A (GB)
Title: Processing an aqueous phosphorus emulsion
IPC: C01B25/12
Filed: 1956-11-09
Abstract: Phosphorus pentoxide is produced by burning a mixture of an aqueous phosphorus emulsion and substantially pure liquid yellow phosphorus, preferably at a temperature of 80-90 DEG  C.  Admixing may be effected at the same temperature by a stirrer or by injection of an inert gas.  The mixture may be covered with a layer of water in which case stirring may be by a slowly operating blade stirrer.  The mixture may be stored in a tank kept at a constant temperature by means of a heating jacket.  The emulsion may be a phosphorus sludge obtained by precipitating with water previously dust-freed phosphorus vapour from a phosphate reduction furnace.  Such sludge may contain 25-75 per cent of phosphorus and 2-4 per cent of solid impurities. It is preferred to use a sludge containing 40-60 per cent of phosphorus and 2 per cent of solid impurities.  The proportion to sludge to pure phosphorus may be 1 : 1-10 and is preferably 1 : 5. The sludge is preferably washed with water before admixing.  The phosphorus pentoxide produced may be hydrated to produce an anhydrous phosphoric acid and may be further diluted to any desired concentration. Suspended impurity in the aqueous phosphoric acid may be removed by filtration.

Title: Improvements in or relating to hardenable epoxide resinous compositions
Inventor: BLOXHAM ERIC JOHN
IPC: C08L63/02
Filed: 1958-10-29
Abstract: A hardenable resinous composition comprises a glycidyl ether containing more than one 1, 2-epoxy group per average molecule and as hardening agent the product obtained by reacting a phenol, an aldehyde and a polyamine containing at least four hydrogen atoms bonded to nitrogen atoms, either by the addition of the aldehyde to the phenol/polyamine mixture or by the addition of the phenol to an aldehyde/polyamine mixture, in such proportions that the reaction product contains at least "three active hydrogen atoms" (which denotes hydrogen atoms which will react with the epoxy groups in the glycidyl ether).  Preferred glycidyl ethers are those obtained by reacting polyphenols such as diphenylol propane with epichlorhydrin or chemically related compounds such as dichlorhydrin or 1, 2-dichloro-3-hydroxy-propane.  In the preparation of the hardening agents there may be used phenol, xylenol or diphenylol propane or a mixture of phenols; formaldehyde, acetaldehyde, paraldehyde and furfuraldehyde; diethylene triamine, triethylene tetramine, tetraethylene pentamine and 1, 6-hexamethylene diamine.  Preferably the phenol and aldehyde are used in equimolecular amounts.  In examples hardening agents are prepared by (a) slowly adding two molecular equivalents of formalin to a mixture of two equivalents of phenol and one equivalent of tetraethylene pentamine at 45 DEG C.; (b) similarly reacting equimolecular proportions of xylenol, 1, 6-hexamethylene diamine and formaldehyde.  The hardening agents can be modified by reaction with ethylene oxide or acrylonitrile. In examples a liquid epoxide resin of epoxide equivalent 190, prepared from diphenylol propane and epichlorhydrin, is hardened with (1) hardening agent A; (2) cyanoethylated hardening agent A; (3) a mixture of hardening agent A and tetraethylene pentamine. The compositions can be used as coating compositions and in glass fibre laminates, brush setting cements, adhesives, foundry patterns, flexible sealing compounds and cable jointing.

Abstract: 304,442. Marks, E. C. R., (Soc. Hardoll- Etablissements Hariveau & Dolimier & R. Porte & Compagnie Reunis). Dec. 23, 1927. Liquid-meters. - Apparatus for delivering measured quantities of petrol &c. comprises two alternately acting measuring chambers 1, 2, and a reversing valve 10, the movement of which is controlled by a piston 8 exposed on its opposite faces to the pressures in the chambers 1, 2, so that the valve cannot move until one vessel is completely full and the other completely empty. The liquid is fed to the chambers 1, 2 through a pipe 13 by a pump 12 and is delivered through a pipe 14. An air pump 15 delivers compressed air through a pipe 16 into the discharging chamber so that the pressure in this chamber on the piston 8 balances the pressure in the filling chamber on the other face of the piston, and prevents the valve 10 from being reversed until the discharging chamber is completely empty and the pressure therein is released through the pipe 14. When the filling chamber is full, the excess liquid supplied by the pump escapes through an overflow valve 18 to the suction side of the pump 12. A non-return valve 20 and a relief valve 21 may be arranged in the air pipe 16. In another form, the valve 10 is of rotary form and is controlled by a pivoted catch operated by the piston 8 and engaging a notched disc on the valve. In another form, the rotary valve has a notched disc engaged by a pin carried by a lever which is connected to a diaphragm exposed on opposite sides to the pressures in the two chambers 1, 2.
