Title: Improvements in or relating to welding
IPC: B23K35/04
Filed: 1928-03-22
Abstract: 301,687. International Nickel Co., Pilling, N. B., and Schoener, J. G. March 22, 1928. Uniting by fusion.-In welding nicked or alloys thereof, such as that sold under the Registered trade mark as " Monel " metal, and containing preferably up to 0.2 per cent of an alkaline earth metal such as magnesium or calcium to render them malleable, the parts are subjected to fusion by an electric arc and the malleabilizing substance is maintained in the melt so as to eliminate any sulphur present and prevent the formation of blowholes. The electrode comprises a nickel or nickel alloy electrode containing an alkaline earth metal such as magnesium or calcium, and preferably also manganese, silicon or carbon, and these elements are retained in the melt by providing a coating or core for the electrode containing a highly reducing metal of high boiling point, such as titanium or a low melting alloy thereof such as ferro titanium, and a metal of relatively low boiling point, such as calcium, preferably in the form of calcium silicon, to form a reducing atmosphere round the arc. Titanium alloys containing from 10 to 30 per cent of titanium, e.g. a low carbon ferrotitanium containing 25 per cent of titanium, together with a calcium alloy containing 15 to 35 per cent of calcium, e.g. calcium-silicon containing 25 per cent of calcium, may be used. The proportion of titanium to calcium may he about 3 to 1 or the titanium content may be 25 to 95 per cent of the combined titanium and calcium contents. The alloys are ground to a fine powder and mixed with liquid binding material such as shellac, and applied to the electrode by dipping or brushing. A suitable coating contains 19 parts by weight of titanium, 6 parts of calcium, 5 parts aluminium, 17 parts of silicon, and 53 parts of iron. The titanium content may aggregate from 0.1 to 10 per cent and the calcium content 0.1 to 8 per cent of the weight of the electrode. Specification 259,967 is referred to.

Abstract: 1,255,777. Metal reinforced plastics. DUNLOP HOLDINGS Ltd. 18 Feb., 1969 [23 Feb., 1968], No. 8849/68. Heading E1K. [Also in Division C3] Metals are bonded to thermoplastic polymers or elastomeric block copolymers by contacting in the presence of compounds capable of reacting to form an aldehyde condensation resin and heating to react them, the compounds being mixed with the polymer before application to the metal. Additionally, the metal can be coated with the compounds. The metal may be continuous sheet, fibres, filaments or cords. The reactant compounds. are (a) a formaldehyde-generator, preferably hexamethylene tetramine, although other compounds are. mentioned, e.g. encapsulated paraformaldehyde, and various melamine and pyridine derivatives, and (b) an aromatic hydroxy compound, (e.g. resorcinol, 1-3 or 1-5 dihydroxynaphthalene) a novolak resin, or melamine or urea, optionally alkylated. Suitably 0.1-10 parts by wt. both of hexamethylenetetramine and of resorcinol are used per 100 parts by wt. polymer. Specified metals are steel, zinc, copper, aluminium, tin and alloys thereof, e.g. brass, "Duralumin" (R.T.M.) Exemplified polymers are polyvinyl chloride, polyvinyl acetate, copolymers of ethylene/ vinyl acetate, and ethylene/ethyl acrylate, and ionomeric ethylene/methacrylic acid copolymers.

Title: Improvements in or relating to the manufacture or treatment of lithium aluminium hydride addition products
Inventor: SCHAEFFER GEORGE WASHINGTON
IPC: C07F5/06
Filed: 1957-03-18
Abstract: The invention comprises the solid 1 : 1 molar addition product of lithium aluminium hydride and a lower tertiary alkylamine, "lower" here and subsequently meaning containing 1-3 carbon atoms in each alkyl radical.  The addition products may be prepared by reacting equimolar amounts of the components, e.g. by contacting the gaseous amine with solid Li Al H4 or by passing the gaseous amine into a solution of Li Al H4 in a suitable dialkyl ether; and by reacting lithium hydride with a 1 : 1 molar addition product of AP H3 with the amine.  By reacting an impure lower tertiary alkylamine containing up to a total of 10% by weight of water, ammonia, lower primary alkylamines and/or lower secondary alkylamines with at least a molar amount of Li Al H1, based on tertiary alkylamine and impurities, separating the addition product from the impurities by evacuating the latter at low temperature, and then decomposing the addition product under vacuum, preferably at room temperature, purified tertiary alkylamine is obtained.ALSO:Lithium aluminium hydride containing aluminium hydride as impurity, e.g. in amounts of 1/2 -10% by weight, is separated therefrom by reacting the mixture with a molar amount, based on LiAlH4 and AlH3, of a tertiary alkylamine containing 1-3 carbon atoms in each alkyl radical while the reactants are in admixture with a dialkyl ether containing 1-3 carbon atoms in each alkyl radical, thereby forming a precipitate of the 1:1 molar addition product of LiAlH4 and the amine, and decomposing the addition product under vacuum, preferably at room temperature, to separate the components thereof.  The reaction and decomposition may be effected by treating the ether solution of LiAlH4 and AlH3 with the gaseous amine, and removing excess amine by distillation through a column containing lithium hydride, which converts the volatile AlH3:tertiary amine addition product into the LiAlH4:tertiary amine addition product.  Removal of ether by fractionation leaves pure LiAlH4 as residue.

In a preferred embodiment, the foam web is supported by a textile web, e.g. a woven or knitted fabric or a tangled fibre fleece or another sheet-like material on the surface thereof remote from the film.
