Patent GB-663097-A (GB)
Title: Manufacture of quaternary salts
IPC: C07D401/12
Filed: 1948-11-05
Abstract: Quaternary sulphates and sulphonates of substituted pyrimidylaminoquinolines useful as trypanocides, are obtained by heating the corresponding halogen acid di-quaternary salts with lower alkyl esters of sulphuric acid, or sulphonic acids, preferably in a solvent having a higher boiling-point than the alkyl halide formed. In examples, methochlorides or methiodides of pyrimidylaminoquinolines joined in the 4-pyrimidyl-position to the -NH- link, and substituted in the 2-pyrimidine position by amino, in the 6-position by methyl, and in the quinoline nucleus by 4-amino and methylamino, and methyl, and joined in the 6-position to the -NH-, are converted into methomethylsulphate, methomethanesulphonate, and metho - p - toluenesulphonate. Generally, the compounds may be substituted in the 2-, 4- or 6-position by amino or lower alkyl amino, attached to the linking -NH- group at another of these positions and further substituted in the remaining 2-, 4- or 6-position by lower alkyl, amino, or lower alkylamino.  4 - Amino - 6(21-aminopyrimidyl - 41 - amino) quinoline monohydrate is obtained by the action of 4 : 6-diaminoquinoline on 4-chloro-2-aminopyrimidine, in presence of hydrochloric acid, rendering alkaline and crystallizing, and may be converted via di-methylsulphate and sodium chloride to the di-methochloride trihydrate.

Patent GB-490576-A (GB)
Title: Improvements in or relating to apparatus for vapourization of fuel, especially heavy mineral oils
IPC: F23C99/00
Filed: 1937-10-25
Abstract: 490,576. Oil-gas generation. SVENSKA AKTIEBOLAGET GASACCUMULATOR. Oct. 25, 1937, No. 29078. Convention date, Nov. 10, 1936. [Class 55 (ii)] [Also in Group XI] In a liquid-fuel vaporizing-apparatus in which the fuel is delivered through parts below the fuel-vaporizing temperature on to a surface above the fuel-vaporizing temperature, an oxygen-containing dilution gas delivered to the vaporizing chamber in a comparatively cold state is mixed with the vapour so rapidly that the mixture is completed before any appreciable increase in temperature of the dilution gas takes place, the mixing and fuel delivery devices being so arranged that the fuel passes through the mixture before reaching the vaporizing surface. Fig. 2 shows a vaporizing chamber 1 receiving heat from a part 2 of a combustion apparatus and maintained at less than atmospheric pressure by connection for example, to the combustion device. Part of the vapour produced by fuel dropping from a pipe 8 through a pipe 7 on to the bottom of the chamber 12 mixes with air drawn through a nozzle 4 and passes through a nozzle 5 to a pipe 6 leading to the pipe 7, the remainder of the vapour mixed with air escaping to the combustion device. The nozzles 4, 5, are so dimensioned that the mixture circulating in the pipes 6, 7, has a dew-point lower than the lowest temperature of the pipe 8 and its mounting 10 and is too rich to ignite spontaneously when entering the vaporizing chamber. The mounting 10 is provided with cooling flanges 9. In a modification the injector device is arranged in a passage connected to the vaporizing chamber and delivers directly into the pipe 7 to which the pipe leading to the combustion device is also connected. In another modification the fuel and air mixture from the nozzles 4, 5 is directed upwardly so as to flow around the fuel delivery nozzle and to circulate in the vaporizing chamber itself. In a further modification shown in Fig. 5, the mixture issuing from the vaporizing chamber rotates a propeller 20 driving a propeller 18 which mixes air and vapour drawn through channels 3, 16 and discharges them through an outlet 17 towards the nozzle 11 of the fuel pipe 8. Specification 490,573, [Group XI], is referred to.

Abstract: 813,177. Strengthening edges. STEVENS, G. W. H. Oct. 5, 1956 [Oct. 14, 1955], No. 29339/55. Class 42 (1). [Also in Groups VII and XIV] The folds of a curtain or skirt when it is draped or hung in use are formed by variations of stiffness along a line or region lower than that of the support, the stiffness varying in a prescribed pattern of three or more sets of maximum and minimum values. The variation in stiffness may be provided by lengths of woven mesh of plasticized cellulose or other plastic filaments sewn to the fabric in overlapping relationship, a continuous member of varying width and/or thickness, a member of uniform stiffness augmented at intervals by shorter members, or lengths of steel strip, wire, stranded cable or other elastic metal which overlap by less than half their length and are covered by a plastic material such as nylon, polythene or polyvinylchloride. The plastic covering may be applied by extrusion or the lengths of metal may be held in overlapping relationship by adhesive tape to enable them to be threaded into a plastic tube. Alternatively, each length of metal may be threaded into a shorter length of tube and its projecting ends threaded into adjacent tubes to form the overlaps. A swaged soft metal alloy sleeve, welding or an adhesive may be used to form joints in the tube. A number of parallel members with corresponding regions of augmented stiffness may be used. Skirts may be triangular or square or the shape shown. In the latter case, the undulations may be uniform and the depth of the drape may or may not vary along the length of the skirt which may be supported on the foundation described in Specification 695,446, [Group VII], when there are more than four regions of augmented stiffness. Specifications 695,540 and 731,920, [both in Group VII]. also are referred to.

Title: A milk powder and composition for addition to flour used in the baking of bread, buns and the like
IPC: A23C1/12
Filed: 1958-09-15
Abstract: A soluble milk base powder is prepared by dissolving or dispersing fats and sugars including honey and dextrose, in milk and evaporating the mix under reduced pressure to a concentrate which is then cooled, impregnated with inert gas, e.g. nitrogen, in a closed vessel, spread out or layered, and dried at reduced pressure to yield a cellular mass, which is reduced to powder, e.g. by milling, containing preferably 30 to 40% milk solids and about twice this amount of fats and sugars.  To produce an additive for flour, the powder is admixed with an emulsion of fruit juices containing pectin, malt, ascorbic and/or lactic acid, and lecithin, as described in Specification 780,333, and to which amino acids have been added, either alone or embodied in a specially prepared sodium caseinate.  The emulsion/caseinate mixture may be dried to a powder, e.g. by inert-gas impregnation treatment similar to that described above for the milk base powder, before mixing with the milk base powder.  If dried in an ordinary fashion, however, the emulsion/sodium caseinate powder, or a concentrate thereof, may be incorporated in the milk base mixture before this is gas-impregnated and dried.  Preferably about 75 to 80% milk base powder is combined with about 20 to 25% of the emulsion/caseinate powder, by weight.  An apparatus for effecting the gas impregnation and subsequent layering is described.

Abstract: 1,009,753. Bearings. LANDIS & GYR A.G. Aug. 1, 1962 [Aug. 14, 1961], No. 29529/62. Heading F2A. A magnetic suspension for a rotor shaft 11 about its axis includes a pair of permanent magnets 30, 35 (Fig. 1) of a material having a coercive force of at least 650 oersteds, the magnet 30 being carried by the shaft 11 and the magnet 35 being fixed, and each having annular pole faces 41, 42 around the axis, directly opposite to and facing like pole faces 38, 39 of the other, the pole faces of each magnet being separated by grooves 43, 40, respectively, of not more than 3 mm. radial width, the faces 41, 42, 38, 39 being of approximately equal area or any difference in area between the outer pole faces 38, 41 and the respective inner pole faces 39, 42 not exceeding 40%, and the magnets 30, 35 being similarly magnetized for repulsion. The magnets are preferably formed of powder composed of the alloy Alnico VII moulded with a thermosetting synthetic plastics material. In a modification (Fig. 4) the upper magnet 82 is also associated concentrically with another cylindrical magnet 90, with pole faces 87, 88 and opposite like pole faces 91, 92, respectively, spaced apart by a groove 89 and 93 not more than 3 mm. wide, and magnetized similarly for mutual repulsion towards concentricity. In the form of Fig. 1 the magnets are stabilized by a partial demagnetization so that in their closest proximity they are not demagnetized further and together support the rotor with an axial gap between them at least as great as the radial width of the groove, having a temperature stability wherein the gap varies no more than 0À003 inch from - 40‹ to 90‹ C. To magnetize the magnet 30 of the magnetic suspension of Fig. 1, it is placed in full face-to-face contact with an electromagnet 51 (Fig. 5) with two magnetizing pole faces 53, 55 matching the pole faces 41, 42 of the magnet 30, passing an initial magnetizing current to the electromagnet 51, then centring the axis of the shaft 11 exactly with respect to the electromagnet pole faces 53, 55 and perpendicular to the plane thereof, and passing a demagnetizing current to the electromagnet 51 strong enough to partially demagnetize and stabilize the magnet 30 to compensate for any deviation of the plane of the pole faces 41, 42 from the normal to the axis of the shaft 11 resulting in some loss of the face-to-face contact upon centring of the shaft axis, so that the stabilized field of the magnet 30 is homogeneous in a plane normal to the shaft axis. The electromagnet 51 has its energizing coil 57 in a gap 56 between the pole faces 53, 55, the windings being close to the plane thereof or from 0À005 to 0À150 inch from that plane. An alternative apparatus to magnetize the magnets of Fig. 1, an apparatus for magnetizing the shaft magnet 82 of Fig. 4 and an apparatus for ring magnet 90 are described.
