Title: Improvements in ball joints
IPC: B60G7/00
Filed: 1961-06-15
Abstract: 945,331. Laminates. FORD MOTOR CO. Ltd. June 15, 1961 [June 15, 1960], No. 17438/61. Addition to 924,972. Heading B5N. [Also in Divisions B2 and E2] A bearing liner for a ball joint comprises a layer 34 of low friction fabric knitted from fibres of low friction synthetic resin material, e.g. polytetrafluoroethylene or linear polyethylene, and an outer layer 36 of elastomeric material, e.g. rubber. The elastomeric material may be applied to the fabric layer by dipping, spraying or moulding. The fabric layer is knitted in sock form so that at each stage in the knitting the most recently formed row of stitches lies on a closed contour, the length of the contour decreasing either at the beginning or the end of the knitting or both, and can therefore be made slightly undersize so that it will stretch to hug the ball tightly. A back-up layer 38 made from plastic material which will shrink upon moulding is injection moulded into the joint between the liner and the socket parts 30, 32. Suitable materials are epoxy resins and nylon reinforced with glass fibre. Alternatively, the back-up layer may be moulded separately from thermoplastic material to a generally cup-shape. With this construction the joint is assembled by stretching the liner over the ball, snapping the heated back-up layer over the liner, and securing the socket parts about the back-up layer. The mouth of the cup has several axial slits to facilitate assembly.

Title: Aromatic carboxylic acids
Inventor: O'NEILL WILLIAM ALEXANDER
IPC: C07C51/265
Filed: 1957-06-05
Abstract: Aromatic carboxylic acids are prepared by oxidizing an alkyl substituted aromatic hydrocarbon in the liquid phase in an organic acid medium by means of oxygen or an oxygen-containing gas in the conjoint presence of a metal and bromine, e.g. a metal bromide, and in the presence of a ketone or other organic compound which forms a peroxide under the conditions of the oxidation reaction.  The reaction may take place using at least 5% and preferably about 20%, by weight of the aromatic compound, of a ketone or other compound such as methyl ethyl ketone, acetaldehyde, benzaldehyde or nitromethane at a temperature lower than usual, e.g. about 80 DEG  C. The use of these four peroxide-forming compounds is exemplified in the oxidation of p-xylene, m-xylene and toluene in an acetic acid medium using oxygen as the oxidizing gas at 80 DEG  or 100 DEG  C. in the presence of cobalt, manganese or barium bromides, or a mixture of cobalt acetate and barium bromide.

Inventor: MILLER ROBERT ARTHUR
IPC: H02K17/36
Filed: 1962-05-09
Abstract: 1,048,762. Control of A.C. motors. PLESSEY CO. Ltd. Aug. 9, 1963 [May 9, 1962], No. 17903/62. Heading H2J. An electric motor comprises two three-phase rotor assemblies on a common shaft, the rotor windings being interconnected through rectifiers 5, 6, 7, associated with resistor 8. The stator windings 3, 4 are energized from a polyphase source through voltage controllers 9, 10, the torques produced by the two stator windings being in opposition. Maximum torque is produced at standstill by advancing the phase of the rotor current with regard to the rotating magnetic field. This is effected by dividing each stator phase winding into two parts, each part of each phase winding being seriesconnected with one of the parts of the next following phase winding. The rotor windings may be arranged similarly. The resistor 8 may be replaced by an inductance, or an additional full-wave rectifier network may be connected between the star-points of the rotor windings 1, 2. In another arrangement, each phase winding on the stator or rotor is divided into three parts, each phase winding being series connected with parts of each of the other two phases.

Patent GB-345167-A (GB)
Title: Improvements relating to compositions of matter for making tools and the like
IPC: H01R4/48
Filed: 1930-06-11
Abstract: Tools such as drawing-dies, extrusion dies, highspeed drills, cutters, saws, &c., and dressing-tools such as grinding-stones, knife-sharpeners, and the like are made of a substance comprising finely divided particles of cutting-agent such as tungsten carbide and a binding-agent such as cobalt, the binding-agent being coated with metal.  In one example the cobalt is pulverized so that it will pass a 200-mesh screen and is then coated with copper either by immersing it in a solution of copper or by electro deposition from a copper solution.  The copper may constitute from ,2 per cent to 20 per cent of the cobalt and is preferably between 2 and 5 per cent. The coated particles are then mixed with a cutting-agent or a mixture of cutting-agents such as tungsten carbide, vitrified zirconium oxide or silicon carbide and the whole mixture subjected to heat and pressure.  The cobalt binding-agent may be replaced by iron or by an alloy steel such as high-speed steel.  Instead of coating the binding-agent with copper, it may be coated with chromium or nickel or first with one of these metals and then with another.  When the binding-agent is coated with copper and chromium, the copper should constitute from ,10-1 per cent-preferably from 1-2 per cent-of the binding-agent, and the chromium should constitute from 1-10 per cent-preferably from 1-3 per cent of the binding-agent.  In one example, the copper constitutes 1,25 per cent of the chromium, about 2 per cent by weight of the binding-agent.  The proportions of the cutting and binding agents may be varied according to the product required.  If brittleness in the product is immaterial 95 per cent of cutting-agent may be used, while if strength and toughness are required in the product 95 per cent of the binding-agent may be used. For cutting-tools the cutting-agent should constitute at least 80 per cent of the composition.  The mixture is heated in a reducing or neutral atmosphere to a p  temperature of about 2800 DEG  F.  The pressure for shaping the article may be exerted either before, during or after heating. Where tungsten carbide is employed, a carbide having approximately 6 per cent of carbon combined with tungsten is utilized.

Title: Improvements in or relating to methods of preparing gels
IPC: C08J9/30
Filed: 1964-04-30
Abstract: A gel which contains gas bubbles is prepared by incorporating a surface-active foaming agent or a gas-evolving agent in an aqueous solution of a macromolecular water-soluble gel-forming substance so as to form small air or other gas bubbles, converting the gas-containing solution into individual particles in a manner such as to retain the gas bubbles in the particles, and treating said particles with a hardening or coagulating liquid to form gel particles containing gas bubbles.  Suitable gel-forming substances are alginates, carboxymethyl cellulose, cellulose ethers and esters, guar gum, starch or viscose.  The surface-active foaming agent may be a fatty alcohol sulphate, an alkyl aryl sulphonate or a polyglycol ether and the gas evolving agent, which is described as being a substance which evolves a gas when it is incorporated in, and is thereby brought into intimate contact with, the aqueous solution, may be aluminium powder.  The individual particles may be formed by centrifuging or spraying the gel forming substance into the hardening or coagulating liquid.  In an example, a solution of calcium hydroxide is used to coagulate droplets of an aqueous solution of sodium alginate.  The gas-containing gel particles may be used as a pore-forming additive either alone or in conjunction with foaming or gas-evolving additives in hydraulic cement compositions such as concrete, gypsum and gas-accumulator compounds, in asbestos cement, building board or tiles of wood, glass or mineral fibres, plastic compounds, ceramic compounds of clay and fireclay and also in tamping compounds.ALSO:Small gas-containing gel particles, in particular those of substantially spherical or spheroidal shape may be employed as pore-forming additives in hydraulic cement compositions such as concrete, gypsum and gas accumulator compounds, in asbestos cement, in ceramic compounds of clay and fireclay and in tamping compounds. The gas-containing gel particles can also be coated or impregnated with Portland cement, gypsum and ceramic compounds, which after drying, and in the case of clay products firing give small hollow beads which can be used as loose insulating material. Suitable compounds from which the gel particles may be formed are alginates, carboxymethylcellulose and other cellulose ethers and esters, guar gum, starch and viscose.

Title: Controlling device for gears
IPC: F16H3/60
Filed: 1923-07-13
Abstract: 201,165. Matteucci, R. July 18, 1922, [Convention date]. Controlling variable-speed gear; reversing-gearing.-A gear member 10 is moved to and held in two extreme gear positions by two co-operating doubly-inclined parts 14, 17. The parts 14 are in the shape of a ring surrounding the parts 17, which are in the shape of teeth upon a set of pivoted levers 16 spring-pressed outwards by a sliding cone 18. The teeth 17 are wedging the member 10 towards the right. To effect change, striking-means engaging a groove 12 thrusts the member 10 positively towards the left. The ring 14 thrusts the levers 16 inwards, the teeth 17 riding up until they engage a groove 15 in a cylindrical part of the ring. This is neutral position. Further movement towards the left brings the other sides of the teeth 17 into action to complete the changing movement. The invention is described as applied to reversing-gearing, the member 10 carrying friction rollers 6 engaging a gear 7 on a driving-shaft 8, and a split internal gear 4 wedged into a cone 2 secured to a driven shaft 3. The levers 16 are pivoted upon the cone 2 and the split gear 4 is connected through a disc 5 and rod 21 to the collar 20 against which the main spring 19 abuts, with the effect that the thrust of this spring tends to wedge the friction gearing into close engagement. This pressure may be supplied by a fluid, by electricity, or by gravity, and the tooth levers may be replaced by balls, rollers, pins or the like.
