Title: Process for the production of caustic alkalies from alkali metal sulphate liquors
IPC: C01D1/04
Filed: 1967-06-16
Abstract: 1,129,427. Caustic alkalies. INVENTA A.G. FUR FORSCHUNG UND PATENTVERWERTUNG. 16 June, 1967 [17 June, 1966], No. 27948/67. Heading C1A. Caustic alkalies are produced by atomizing aqueous alkali-metal sulphate liquor in a burner flame, mixing with hydrocarbon vapour and subjecting to a temperature of 1000-1400‹ C. for 60-180 seconds, the hydrocarbon undergoing thermal cracking to provide sulphatereducing compounds in excess of the amount required for reduction. A suitable hydrocarbon is a high-boiling naphthenic petroleum. Combustion of cracked hydrocarbon may provide some of the heat required for reaction. As shown, oil vapour, compressed air and sulphate liquor are preheated in heat-exchanger 12. Gas burner 2 is supplied with recycled cracked gas, air and sulphate liquor via conduits 10, 3, 4. Atomized liquor is mixed at 5a with oil vapour from conduit 5; alkali metal hydroxide is produced in reaction chamber 1, and withdrawn at 8 after separation from gases in reactor sump 6 and cyclone 7. Part of the gas stream passes to conduit 10 for use in burner 2; the remainder is burnt at 11 with air from 14 to provide heat for exchanger 12. In the example, the sulphate liquor is a spent liquor contaminated with hydrocarbons and originating from an organic synthesis.

Title: Improvements in or relating to grinding machines and tool head units therefor
Inventor: SLATER FRED
IPC: B24B53/04
Filed: 1951-11-29
Abstract: 734,269. Trueing grinding-wheels. BROCKHOUSE & CO., Ltd., J. Dec. 1, 1952 [Nov. 29, 1951], No. 27980/51. Class 60. A trueing unit is removably or displaceably secured to a grinding machine and includes means for reciprocating a trueing tool 65 along a rectilinear path which lies in a plane diametrical with respect to the axis of the grinding-wheel 14 and means for adjusting the angular relationship between the path and the axis. The tool, which may be a diamond, is mounted on a part-cylindrical holder 34 having rack teeth in engagement with a gear 58 or a sector which is oscillated by a handle 64 to reciprocate the tool along its trueing path. To enable the angle of this path to be varied the holder is mounted in a guide on a sector-shaped carrier 32 pivotally connected to a ribbed supporting plate 16 by a flanged bush (not shown) concentric with the gear 58. Angularlyspaced bushings 42 co-operate with one of two spring-loaded plungers 43 mounted in the plate 16 to lock the carrier in the required position. The bushings may be spaced at angular intervals of 10 degrees while the angular relationship between the two plungers is such that angular settings of the carrier at intervals of 5 degrees may be obtained. The plate 16 is formed with a rectangular recess to receive upper and lower bars 24 secured by screws 25. These bars form a dovetailed slideway for a member 15 along which the plate 16 may be adjusted by a screw and nut device 27. The member 15 is clamped to the tool spindle casing 10 by bars similar to those shown at 24 and may be adjusted radially of the tool spindle by loosening one of these bars. An integral facing 13 enables the tool spindle casing to be connected to a part of the machine tool such as a compound slide system. Frusto-conical wheels having their smaller ends directed away from the tool spindle casing may be trued by mounting the holder 34 for movement in a direction at right angles to that shown and providing it with a bracket having a series of holes in any one of which the trueing tool may be secured by a set-screw. Alternatively, the range of angular movement of the carrier may be sufficient to enable it to be positioned for trueing of wheels mounted either way. In the latter case, the member 15 may be parallel with the tool spindle and have a horizontal slideway for the trueing tool holder at or near its lower end. The trueing device is intended for use with slideway grinders. Specification 734,340 is referred to.

Filed: 1922-06-29
Abstract: 191,348. Stott, J. H. June 29, 1922. Laminar springs.- To cause the overhanging type of leaf springs, and particularly of the springs described in Specifications 188,428 and 190,537, to bend uniformly under load, they are shaped in breadth only, in depth only, or in both breadth and depth. If tapered in depth only, they are shaped to approximate to a curve in which the depth of any section varies as the cube root of the distance of that section from the extremity. If shaped in breadth only, the shape is that of an isosceles triangle with the apex widened into a rectangle, as shown in Fig. 4; the rectangular tip may be slightly tapered. The tip may alternatively be shaped as in Fig. 5, where two isosceles triangles with their apices extended are placed side by side, or as shown in Fig. 6, where the tip is formed of two half triangles. If the tips are shaped in both breadth and depth, the depth curve is modified accordingly. When applied to springs as described in Specification 190,537, the rectangular tip ends are made of sufficient length to form attachments for the bearing-strips or rollers. Specifications 21869/14, 118,176, [Class 79 (iii), Motor vehicles, Arrangement &c. of parts of], and 118,293, are also referred to.

Title: Derivatives of dihydrosantonin
Filed: 1954-10-04
Abstract: The invention comprises compounds of the formula <FORM:0768729/IV(b)/1> in which R is hydrogen or methyl, Z is a carboxyl, esterified carboxyl, carbonamido, cyano or acyl group and the lactone ring is trans fused, and their preparation by treating a compound of the formula <FORM:0768729/IV(b)/2> where U is an acyloxy group and Y is a carboxyl, esterified carboxyl, carbonamido or cyano group with an oxidizing agent. Suitable oxidizing agents are hydrogen peroxide and organic peracids such as performic, peracetic, perphthalic and perbenzoic acids.  Preferably the oxidizing agent is produced in situ from an organic acid or anhydride and hydrogen peroxide.  The reaction is suitably carried out in a solvent such as a carboxylic acid, alcohol, acetone or dioxane and may be catalysed by ferrous sulphate.  Compounds of the general formula (I) in which Z is other than carboxyl may be converted to the carboxylic acid by hydrolysis.  The products may be converted into santonin or its derivatives by dehydrogenation of the octahydronaphthalene ring at the 3- and 4-positions by treatment with selenium dioxide or by halogenating or acyloxylating at the 3-position followed by treatment to eliminate hydrohalic acid or the acid corresponding to the acyl group.  In examples (2 - acyloxy - 1 : 10 - dimethyl - 3 : 4 : 5 : 6 : 7 : 10 - hexahydro - 7 - naphthyl) - malonic acid or corresponding esters, amides, nitriles or acyl acetic acids of the general formula (II) above are oxidized by hydrogen peroxide in the presence of a carboxylic acid or its anhydride to give the trans fused lactones of methyl hydrogen (2 - keto - 8 - hydroxy - 1 : 10 - dimethyl 2 : 3 : 4 : 5 : 6 : 7 : 8 : 10 - octahydro-7-naphthyl)-methylmalonate; ethyl hydrogen (2 - keto - 8 - hydroxy - 1 : 10 - dimethyl-2 : 3 : 4 : 5 : 6 : 7 : 8 : 10 - octahydro - 7 - naphthyl)-methylmalonate, which is converted into the free acid by hydrolysis and ethyl hydrogen (2 - keto - 8 - hydroxy - 1 : 10 - dimethyl - 2 : 3 : 4 : 5 : 6 : 7 : 8 : 10 - octahydro-7-naphthyl)-malonate.

Abstract: 988,546. Printing apparatus. TIMSONS (HOLDINGS) Ltd. July 24, 1963 [July 26, 1962], No. 28693/62. Heading B6C. In a rotary offset printing machine in which a web W is simultaneously printed on both sides by printing couples 3, 4 and is subsequently dried by gas flames ejecting from burners 18 in a drying chamber 17, the printing and drying operations are automatically stopped should the web movement cease or slow down from a predetermined speed. The combined offset impression cylinders 3 and the inking forme rollers 10 with their associated inking drums 9 are adapted to be swung away from the web and the associated plate cylinder 4, respectively, by solenoid actuated lever and linkage mechanisms 11, 13 on the receipt of an appropriate electrical signal at a box 12. This signal is derived from an electrical electronic control system 29 which acts in response to the voltage generated by a generator 28 driven through a chain drive from a roller 26 over which the web moves. The control system, which also effects the operation of gas valves 20 in the burner supply conduits 22, comprises a transistorized circuit which causes the relays to be fully energized very quickly. This tends to prevent the chattering and sparking at the relay contacts, which is normally present at the breaking and making voltages in most relay circuits. The system also acts to automatically re-start the printing and drying operations as the web regains its normal and predetermined operating speed. Specification 869,903 is referred to.

Title: Improvements in coating compound and method for production thereof
Filed: 1936-10-23
Abstract: A coating-composition is produced by blending a partially condensed thermo-setting phenol-formaldehyde resin with a metal-adherent resin in a common solvent containing at least 5 per cent (reckoned on the phenolformaldehyde resin) of a high-boiling solvent.  Specified metal-adherent resins are fatty-acid modified or blown castor-oil modified polyhydric alcohol-polybasic acid resins, e.g. glycerol-phthalic anhydride resin modified by non-drying or drying oil fatty acids such as linseed and wood-oil acids; natural gum fossil resins, e.g. Kauri; and the gasoline-insoluble portion of oxidized abietic acid known under the Registered Trade Mark "Vinsol." The high-boiling solvent may be a phenol, e.g. cresol or xylenol, cyclohexanone, methyl cyclohexanone, cyclohexanol, benzyl alcohol. The composition may be used as a primer; as a coating on concrete and metals such as galvanized iron or aluminium; for the coating or impregnation of rubber and fibrous materials, e.g. wall, gypsum, or open-pore insulating boards, to protect them against termites or fungi; and may be mixed with white lead.  In an example: m- or other cresol is condensed with formaldehyde, or a polymer thereof, e.g. paraformaldehyde, in the presence of caustic soda until a sample cooled to room temperature is a stiff gel, the resin is separated from the water of condensation, and there is added 10 per cent of m-cresol and 20 per cent of denatured ethyl alcohol followed by 10 per cent of fatty-acid modified polyhydric alcohol-polybasic acid resin, as solid or in solution, (all percentages being reckoned on the phenol-formaldehyde resin).
