Title: Improvements relating to the purification of nitrogen containing hydrocarbon liquids
IPC: C10G17/06
Filed: 1960-03-29
Abstract: A process for the complete or partial removal of nitrogen compounds from a liquid mixture of hydrocarbons which contains unsaturated hydrocarbons and which boils in the gasoline range, or from an oil obtained by heating oil-containing shale, or from a distillation product obtained in working-up tar, e.g. crude benzene, comprises passing the hydrocarbon mixture concurrently with sulphuric acid of at least 65% concentration over a hydrophilic contact bed of solid inert material with a contact time of less than 30 seconds, so that no substantial polymerization of the unsaturated hydrocarbons occurs in the bed. Suitably gasoline to be treated is a cracked gasoline having an A.S.T.M. boiling range of 40 DEG  to 205 DEG C. or 110 DEG to 210 DEG C.; such gasolines may be obtained by thermal or catalytic cracking or by thermal reforming.  The contact bed may consist of ceramic material, coke pretreated with an organic solvent, glass, pumice, or an ion exchange resin, e.g. of the sulphonated polystyrene type, and may be in the form of Raschig rings, Berl saddles, Dixon packing, beads or fibres, the particle size being 0,5 to 10 mm.; the bed suitably consists of layers, each layer being formed of particles of about the same size, and the particles of the different layers differing in size.  If acid of 98% concentration is used for treating gasoline, the contact time is less than 10 seconds, but with acid of any strength the contact time is preferably greater than 1 second whatever the feed.  The entire surface of the contact bed is preferably wetted with sulphuric acid before the hydrocarbon mixture is passed through, and the mixture of hydrocarbons and acid are thereafter passed into the bed in such quantities and in such directions, preferably downwards to prevent acid collecting at the bottom of the bed, that the two liquids leave the bed as continuous phases.

Abstract: 945,093. Vehicle theft alarms. COMPAGNIA ITALIANA WESTINGHOUSE FRENI E SEGNALI, and GISBERTO PRETINI. March 29, 1960 [April 6, 1959], No.11070/60. Heading G4N. [Also in Division F1] An anti-theft alarm device for vehicles is operated pneumatically and comprise means for (1) automatically closing a door or doors of storage recesses provided in the vehicle (2) operating a siren (3) interrupting the vehicle fuel supply or ignition circuit. The apparatus of Fig. 1 is for a diesel vehicle having four storage recesses closed by doors connected with valves 13,14,15, 16, to vehicle doors being connected with valves 64, 65, 66, 67. Setting of apparatus. Lever of valve 11 is depressed, connecting actuators 20,21,22,23 which can lock the recess doors to atmosphere. Compressed air from reservoir 3 is supplied to a cylinder 38 the piston in which releases that of a fuel supply valve. Pipes 40, 40<SP>1</SP> connected to actuators 20 .. 23 are exhausted and compressed air is admitted to a timing reservoir 35. The lever of valve 11 can now be released. After closure of the vehicle and recess doors and opening of a lock 28 the apparatus is fully set. Operation of apparatus. The opening of a vehicle door causes one of valves 64-67 to open and connect pipes 27<SP>1</SP>, 27 to atmosphere, then causing valve 7 to assume its "release" position in which pipe 31 is cut off and pipe 24 connected to supply pipe 6. Compressed air is, therefore, supplied to actuators 20-23 to lock the recess doors. After a delay due to reservoir 35,valve 10 releases to operate a pneumatic switch 42 to energize alarm siren 43. Compressed air is also supplied to cylinder 39 to cut off the fuel supply. The arrangement is such that attempted simultaneous opening of two or more of the recess doors will operate the alarm lock the recess doors and cut off the fuel supply, even though the vehicle doors are open and the isolating cock 28 turned off, for instance on arrival at a destination. The recess doors must be opened (or closed) one after the other a short time delay to avoid actuation of the alarm. A further arrangement (Fig. 2, not shown) includes only one recess, and the ignition circuit is interrupted.

Title: Thickened liquids, pastes, sludges and suspensions
IPC: A61Q11/00
Filed: 1955-04-18
Abstract: Natural substances containing free or combined silica are treated in aqueous suspension at 150-280 DEG  C. under elevated pressure with an alkaline earth metal hydroxide, the solid : liquid ratio in the suspension being at most 1 : 6, whereby improved silicate products are obtained, which are used to thicken liquids.  In a modification, the products are after-treated with an acid or acidic agent, e.g. sulphur dioxide or carbon dioxide, to form neutral or acid silicates, or silica.  Initial materials mentioned are clay (bentonite), kaolin, loam, sand, kieselguhr and quartz powder; in the examples, the hydrothermal process used is that described in Specification 804,834. Liquids may in general be thickened until they are of a paste-like consistency or are in the form of powders, but acid liquids are not successfully thickened.  The silicate or silica may be mixed with other thickening agents such as pyrogenically prepared oxides, and may be loaded with an organic amine or alcohol.  They may be used in an amount of only 10 per cent.  Liquids referred to are paraffins, waxes, resins, bitumens, asphalts and sealing tars, in addition to liquid soap solutions (e.g. soft soaps), bleaching agents and detergents for dry bleaching, oils and liquid greases for solid lubricants or gel greases and the liquids used in lacquers.  When used in the latter compositions, the settling of pigments and fillers is delayed, and a matting effect is obtained. Examples refer to (1) the thickening of water, by materials obtained from bentonite and quartz, some of which were subsequently extracted with hydrochloric acid; (2) thickening of paraffin oil with acid-extracted bentonite and quartz products and an unextracted quartz product; (3) sedimentation retarding of lithopone with and without blancfixe and of micaceous iron ore, in lacquer linseed oil media, with acid-extracted bentonite and sand products.ALSO:Adhesives are thickened and sedimentation of fillers, e.g mineral fillers, therefrom is retarded by the addition of a silicate obtained by hydrothermal treatment of a silica-containing natural substance with an alkaline earth metal hydroxide, or of a silicate or silica thus produced and subsequently reacted with an acid or acidic substance (see Group III).  Specification 804,834 [Group III] is referred to.ALSO:Liquids such as glycol or glycerine suitable for use in cosmetics or in dentifrices, and ethereal oils suitable for use as additives to powder, may be thickened by the addition of a silicate obtained by hydrothermal treatment of a silica-containing natural substance with an alkaline earth metal hydroxide, or thickened with a silicate or silica thus produced and subsequently reacted with an acid or acidic substance (see Group III).  Specification 804,834, [Group III], is referred to.
