Patent GB-727088-A (GB)
Title: Preparation of titanium from alkali metal titanium double fluorides
IPC: C25C3/28
Filed: 1953-02-02
Abstract: Titanium is produced by reacting an oxidic titanium compound with an alkali metal fluoride to form a double fluoride of titanium and alkali metal which is then incorporated in a fused halide salt bath, electrolyzing the resultant fused bath to decompose the double fluoride and cathodically deposit metallic titanium, separating the metallic titanium from the spent bath and using the spent bath as a source of alkali metal fluoride for reaction with oxidic titanium compound.  The titanium compound may be ilmenite or other ores, titanium oxides, meta-titanic acids, slags containing high percentages of titanium dioxide and titanium sulphate.  When ilmenite is used the iron content is first reduced by carbon, a reducing gas or furnace atmosphere or by the addition of scrap iron and sulphuric acid and the alkali metal fluoride then added.  In one example of batch production, scrap iron and sulphuric acid are added to ilmenite and the insolubles, e.g. silicates, are removed.  To the hot solution alkali metal fluorides are added, if desired, with alkali metal chloride from the electrolysis in proportions of one mole of titanium sulphate to 2 moles of fluoride and 4 of chloride, a slight excess of fluoride being preferred.  The alkali metal titanium fluoride may be crystallized from the solution.  Two-thirds of the total fluoride addition may first be added to the titanium sulphate, the product filtered and the remaining one-third added.  This double fluoride is then electrolyzed.  The titanium is removed as a spongy mass from the cathode.  Alternatively, the process may be a continuous one, alkali metal fluoride with some alkali metal chloride from the bath being recycled continuously to form the double fluoride.

Patent GB-998973-A (GB)
Title: Novel method for curing polyepoxides
IPC: C08L63/00
Filed: 1962-01-26
Abstract: Polyacids containing at least two thioether groups and at least two carboxylic groups are obtained by reacting a mercapto acid with a compound containing terminal olefinic double bonds.  In examples mercapto acetic acid is reacted with (B), dicyclopentadiene; (F) 10-undecenoic acid; (G) diallyl ether; (H) diallyl maleate and (I) diallyl phthalate.  The products are used as curing agents for polyepoxides (see Division C3).ALSO:A polyepoxide is cured with a stable polyacid containing at least two thioether groups each connected through a carbon chain with a carboxylic acid group. Suitable curing agents are adducts of polymers or copolymers (e.g. with styrene) of butadiene (e.g. known under the Trade names "Buton," "Butareg" or "Naugapol") and mercapto acids (Examples A, C, D, E, K); or adducts of mercapto acids with diallylether (Example G) or with polyallyl ethers of alcohols such as mannitol, sorbitol, glycerol or starch, or with polyallyl esters of acids such as phthalic, maleic, citric, or pyromellitic acid (Examples H, I), or with polyallyl esters of the copolymer of maleic anhydride and styrene, or with unsaturated polyesters, e.g. from glycols and maleic or fumaric acid (Example J), or with an unsaturated acid, e.g. 10-undecenoic acid (Example F), or with dicyclopentadiene (Example B).  The preferred mercapto acids are mercaptoacetic, mercaptopropionic, mercaptobutyric and mercaptopentanoic acids. Polyepoxides specified are: condensates of bisphenol A with epichlorohydrin (e.g. EPON 828, 1001); polymers of allyl glycidyl ether; glycidyl ethers of phenol-formaldehyde condensates; glycidyl ethers of polyhydric alcohols; 1,2-epoxy-3,4-epoxy-butane; diglycidyl ether; limonene diepoxide; diepoxy-dicyclopentadiene; epoxidized glycerides; epoxidized butadiene polymers; vinyl cyclohexene dioxide.  A number of examples are given, the polyepoxides and curing agents being generally dissolved in a suitable solvent, e.g. methyl isobutyl ketone, or dibutoxyethyl adipate.  Example 9 includes Neoprene WRT in the mixture to be cured.ALSO:In Example 4, films of methyl isobutyl ketone solutions of various polyepoxides with a curing agent formed from a butadiene-styrene copolymer and mercaptoacetic acid are coated on glass plates, dried and cured.  Polyepoxides used are the glycidyl ether of bis(4-hydroxyphenyl)-dimethyl methane; 4-vinyl cyclohexene di-epoxide; limonine diepoxide; dicyclopentadiene diepoxide; epoxidized soya oil; and an epoxidized butadiene polymer known as "Oxiron 2000".  In Example 9, a mixture of a polyepoxide known as "Epon 1001", "Polyacid K" formed from a commercial rubber product and mercaptoacetic acid, and "Neoprene WRT" is dissolved in toluene, coated on a primed film of oriented polyethylene terephthalate, dried and cured to a flexible coated film.

Abstract: 180,631. Compagnie des Forges et AciÚries de la Marine et d'HomÚ- court. May 26, 1921, [Convention date]. Ordnance, multi-charge; breech mechanism; chambers.-In order to adjust the size of the powder chamber when charges of different sizes are fired, one or more laterally disposed auxiliary chambers 2, Fig. 4, are provided which open directly into the normal chamber 3 in rear of the base of the projectile. The auxiliary chambers are plugged when not in use, but receive metalcased cartridges or loose charges when the range is to be increased by increasing the charge. The auxiliary charge is ignited by the flash from the main charge. The Specification as open to inspection under Sect. 91 (3) (a) also describes safety means, such as a vertically sliding rod 11 bearing on the main breech-block 9, to prevent the operation of the lever 14 for opening the auxiliary breech-block 10 when the block 9 carrying the firing gear is in firing position. The rod 11 is also prevented from rising by a stop surface x on the lever 14 when the block 1C is open, thereby arresting the closure of the block 9 under danger conditions. As shown in Fig. 9 (Cancelled), a conical, or alternatively a stepped cylindrical chamber may be provided, a portion of the chamber being plugged by a member 21a when the small chamber 18<a> is in use. Obturation is effected either bv the cartridge cases or by separate members 27a of the metal or plastic type provided on the breechclosure 17. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in percussion fuses for projectiles
IPC: F42C1/02
Filed: 1927-02-03
Abstract: 265,955. Brandt, E. W. Feb. 9, 1926, Projectile fuzes.- The firing pin is deformed on striking a screen between it and the percussion cap if the impact is weak, as when it occurs by accident, so that penetration of the percussion cap cannot then occur, whereas on impact at high speed, such as happens when the projectile strikes a target, no appreciable amount of deformation takes place, and the firing pin is able to penetrate and fire the percussion cap. In a modification, the blow of the impact may be transmitted to the deformable firing pin I<3>, Fig. 10, by air pressure from a plunger X. When this is driven in quickly, flap valves R close up and a strong pressure is transmitted to the firing pin; but a slow movement of the plunger, caused by a weak impact, is unable to close the valves R, and cannot therefore impart a sufficient blow to the firing pin. In another modification, Fig. 7, the firing pin I<2> is stayed by lateral masses S if the impact is strong; but, if the impact is weak, the masses S move sideways, and the firing pin collapses and fails to fire the percussion cap L<2>.
