Inventor: RAPSON FREDERICK LIONEL
IPC: B60S9/22
Filed: 1918-04-30
Abstract: 129,055. Rapson, F. L. April 30, 1918. Stands or supports for vehicles. - Lifting-jacks are attached to the vehicle by hinge or swivelling joints and are automatically locked in the operative and inoperative positions. The swivelling connexion shown in Fig. 2 is secured to the axle 6 by the' screwed extensions 8 of the device 5 and the plate 9, and spring-pressed plungers or balls 11 engaging in recesses 12, 13 of the plate 4 secure the jack 1 automatically in a vertical position or an horizontal position close in to the axle or under the vehicle springs. The jack is detachably held in its inoperative position by a spring clip 14. When the jack element 1 is secured to the rear axles, it is swivelled at its upper end, and the spring clip 14 may be carried off a bracket formed on the swivel attachment device 5. The swivelling device may be arranged at right-angles to the axles of the vehicle, and it may be arranged on the vehicle spring 15 as shown in Fig. 8. A brace handle may be used to operate the jacks, and the handle may be formed with a hook or recess to aid in lifting or lowering the jacks. The feet of the jacks may be spoon-shaped or fitted with bolts or rollers. Any form of jack element may be used, such as the jacks described in Specifications 122,216, 122,389, [Class 78 (iii), Lifts &c.], and 129,053.

Title: Oil and varnish colours miscible with water
IPC: C09D5/02
Filed: 1921-03-07
Abstract: 183,177. G³nter, F. March 7, 1921. Water paints.-Paints which may be diluted with water for use comprise a pigment, a medium such as a drying oil, or a solution of resin, water, and a stabilizing-agent soluble in water and in the medium. The stabilizing- agent may be a volatile substance such as alcohol, pyridin, acetone, or naphthenic acid, with or without an admixture of a less volatile agent such as glycerine or Turkey red oil, or it may be an ammonia or alkali soap of a resinous acid or of a drying fatty acid.. When alkali soaps are used as stabilizing-agents, an oxidizable non-metallic element such as sulphur, phosphorus, or selenium is added, thereby producing acids which act on the soaps and produce insoluble compounds. The fatty acids set free from the soap by this reaction may themselves function as the binding medium, Oils partly hydrotyzed by means of enzymes such as are found in castor oil seeds may be used as media, the free glycerine present acting as stabilizing- agent. The ingredients may be initially mixed without water, and the stabilizing-agent may also be omitted and dissolved instead in the water used for dilution. Suitable binding-agents are linseed oil, hemp-seed oil, poppy oil, walnut oil, and wood oil.

Abstract: 1441044 Black iron oxide pigment LAPORTE INDUSTRIES Ltd 10 Feb 1975 [21 Feb 1974] 7882/74 Heading C1A A process for the production of black iron oxide pigment having a blue undertone comprises two or more stages, each comprising firstly treating an aqueous solution of FeSO 4  with a neutralizing agent to precipitate, in the first and any interemediate stage, a part only of the Fe values therein and then oxidizing the, precipitate formed in the first and any intermediate stage to a Fe<SP>+2</SP> : Fe<SP>+3</SP> ratio above 1 : 2 by treating a suspension thereof with an oxidizing gas, wherein the precipitate in the second and any succeeding stage is formed and oxidized in the presence of the oxidized precipitate(s from the preceding stage(s), the oxidation at each stage being conducted at a temperature at least 50‹ C. if the pH is in the range 2-5, and oxidizing the final combined precipitates to black iron oxide. The starting material is preferably a solution of copperas, e.g. from the sulphate preparation of TiO 2 . The initial solution preferably has a Fe<SP>+2</SP> concentration of 10-60 g./l. The quantity of neutralizing agent used in the first stage is preferably sufficient to react with 30-95% of FeSO 4  and is preferably used in excess, e.g. of up to 20% in the final stage. Ammonia is the preferred neutralizing agent, preferably in the form of aqueous NH 4 OH. The precipitation is suitably conducted in each stage with stirring at 50-90‹ C. Each stage, other than the last, employs sufficient neutralizing agent to react with 70-95% of the sulphate. The oxidation is suitably accomplished by bubbling the gas, e.g. air upwardly through the aqueous medium containing the precipitate for 1-4 hours at 50-95‹ C. The precipitate formed in the first and any intermediate stage are preferably oxidized to a Fe<SP>+2</SP> : Fe<SP>+3</SP> ratio of 1-2 : 1, particularly 1À3-1À7 : 1. The combined oxidized precipitates may be allowed to settle or be recovered by filtration and are preferably washed until free of SO 4 . The product may be dried at 50-120‹ C. or spray-dried, the dry product is suitably milled to produce a pigment.

Title: Preparation of organopolysiloxanes containing silicon-bonded carboxyalkyl radicals
IPC: C08G77/14
Filed: 1958-03-12
Abstract: Siloxane copolymers are made by effecting reaction between an aqueous solution of a carboxyalkylpolysiloxane and a silane of the formula RmSi(OR1)4-m, where each R is a monovalent hydrocarbon or halogenated hydrocarbon radical, each R1 is a lower alkyl radical, and m is 1, 2 or 3.  The preparation of the carboxyalkylsiloxanes and the corresponding cyanoalkylsilanes from which they are made, are described.  The water-soluble carboxyalkylsiloxane is preferably used in amount of from 0,1 to 95 mol. per cent.  In making the copolymer, the siloxane and silane are dissolved in water and warmed to a temperature within the range of 30 DEG  to 75 DEG C. to give an intercondensed product which is isolated by removing the water under vacuum.  This product will further condense, by heating, e.g. at 125 DEG  to 200 DEG C., to the cured solid state.  Examples are given. Uses: as emulsifying or surface active agents; for waterproofing fabrics or for moulding purposes; and as intermediates in making esters which are useful as plasticizers for other siloxane rubbers and resins.
