Title: Improvements in or relating to the production of finely divided metal oxides
Inventor: MAS ROBERT JEAN
IPC: C01B33/18
Filed: 1962-07-17
Abstract: Finely divided metal oxides are produced by feeding hot, burnt gases from an auxiliary flame in a separate combustion chamber, as a rectilinear moving stream into an elongated reaction chamber in a direction along or substantially parallel to the axis of the reaction chamber, and injecting a mixture of metal chloride vapour and oxygen into the periphery of the stream from a plurality of directions, each of which intersects the axis of the feed of the burnt gases (e.g. at 45 DEG -90 DEG ).  Chlorides which may be used are those of Ti, Zr, Al, Sn, Cr, Fe, Si, HP, and Nb.  The auxiliary flame is preferably a CO flame, and the chloride/oxygen mixture may be initially at 120 DEG -150 DEG  C., while the burnt gases into which the mixture is injected may be at 1900 DEG  C.  Steam may be added to the O2 or CO, or AlCl3 or SiCl4 may be added to the chloride stream.  The process is described in relation to apparatus described in Specification 1,047,714.

Patent GB-297839-A (GB)
IPC: C07D473/04
Filed: 1928-09-27
Abstract: 297,839. Glucksmann, E. Sept. 29, 1927, [Convention date]. Salts of halogen-substituted aliphatic tetraammonium bases such as the salts of (C2H5)3N (OH).C2H4Br are made by reacting a salt of such base with a metal salt of the desired acid, the metal being preferably one which forms an insoluble salt with the anion of the initial tetraammonium salt. In order to avoid the decomposition of the product the carbon-bound halogen atom is protected from the action of hydroxylions, especially those produced by the dissociation of the salt itself, for instance by adding an excess of the acid to be bound to the tetra-ammonium base, in which case the product may be separated by evaporation and crystallization; or by precipitation of the product before the hydrolysis has attained an appreciable extent, for instance by reacting upon the hydrohalogen salt of the tetraammoninum base with the silver salt of the acid to be bound in aqueous solution and precipitating the product (after separating the silver halide) with acetone, or, when an alcoholic solution is used, with ether. Alternatively the halogenide of the tetra-ammonium base may be reacted with silver sulphate, the resulting sulphate being then reacted with a salt of the desired acid with a metal such as barium which forms an insoluble sulphate; the product may be recovered by precipitation or evaporation or cooling to a very low temperature. When an acid salt of a polybasic acid is to be produced, the double decomposition is effected with an acid salt of the acid to be bound to the tetra-ammonium base, or a molecule of the acid is added to the neutral salt.

Filed: 1928-09-27
Abstract: 307,045. Dugelay, P. March 3, 1928, [Convention date]. Cylinders receiving liquid fuel. - In engines wherein ignition in a cylinder is normally effected by a small hot charge from a cylinder preceding it in igniting order, elongated combustion chambers 109 are used. A valve-controlled connection with. a companion cylinder 107 is formed in a short pipe; the charges in cylinder 107 are ignited by a flame from the cylinder 108. Liquid fuel is admitted to the combustion chamber through a nozzle 112 and air enters by a valve 114. When working with combustible mixture the valve 114 serves as an admission valve for the combustible charge. By suitably timing the valve 111 scavenging air from one cylinder may enter a companion cylinder, the passage of the air freeing the combustion chamber of burnt gases. At starting, ignition is effected by a sparking-plug 113 or by the heat of compression.

Abstract: 534,745. Detergents. CROSFIELD & SONS, Ltd., J. Oct. 13, 1939, No. 27815. Convention date, Oct. 31, 1938. [Class 91] Alkali ,metal silicate detergents are made from anhydrous alkali metal silicates obtained by fusing a mixture of sand and an alkali metal salt, by finely pulverizing the silicate, mixing therewith a finely divided compatible alkaline detergent compound which is more quickly soluble than the silicate, agitating the mixture in the presence of a small amount of water sufficient thoroughly to moisten the mixture and to produce a cementing action, and continuing the agitation at hardening temperatures until the moist mass is converted into dust-free granules comprising an aggregate of anhydrous silicate particles embedded in a matrix of the detergent compound. The silicate compound is represented by the formula Me 2 O(SiO 2 ) x where Me is an alkali metal and x preferably lies between 0.5 and 2.0; in the examples sodium meta silicate, prepared by fusing soda ash with sand, is used. The preferred alkaline detergent compounds are alkali metal hydroxides, carbonates, borates, phosphates and soaps. In the examples, caustic soda flakes, soda ash, and trisodium phosphate are used as the alkaline detergent compounds.
