Title: An improved friction clutch
IPC: F16D13/04
Filed: 1934-10-30
Abstract: 441,897. Friction clutches ; variablespeed gearing. BOLTON, A., 182, Radford Road, Coventry, and ENGLISH, J., North Leam, Felling, Gateshead-on-Tyne. Oct. 30, 1934, No. 31043. [Class 80 (ii)] In a friction clutch, a pair of cones b, b<1>, mounted loosely on the driving shaft e and cooperating with a hollow double-conical member c, c<1> splined on the driven shaft i, have V- shaped projections b<2> coacting with similar projections a3 on a pair of members a, a<1> which are interposed between the cones b, b<1>, are splined on the shaft e, and are urged apart by springs d. The clutch pressure thus increases automatically with the torque transmitted in either direction. The cones b, b<1> are caused to turn in unison by means of dowels f <1> extending thereinto from a loose ring f. The clutch is disengaged by moving a collar m, splined on the shaft e, towards the member b, the collar having V-shaped teeth m<1> coacting with similar teeth on the member b. The cone b<1> is adapted to abut against a collar r fixed on the shaft e; this collar may also have V-shaped teeth coacting with similar teeth on the member b<1>. The collar m is controlled by a fork n fitted with friction material o, so that on disengagement of the clutch the shaft e is braked. When used as the tail clutch of a motor-vehicle gear-box, the fork n is connected with the main clutch pedal in such a way that the main clutch disengages first, but the tail clutch engages first. According to the Provisional Specification, the members a, a<1> are formed as a single member fixed to the shaft e, the springs d being replaced by springs arranged between the cones b, b<1>, and the clutch may be arranged between the gear-box and the main clutch, which latter may be replaced by a fluid coupling.

Title: Bis (1-aminocycloalkylmethyl) amines
Filed: 1956-10-12
Abstract: Bis - (1 - aminocycloalkylmethyl) amines are prepared by catalytic hydrogenation of bis-(1-nitrocycloalkylmethyl) amines. The process may take place in the presence of a suitable solvent, e.g. methanol, ethanol, isopropanol, dioxane, benzene, cyclohexane, and petroleum ether, also mixtures of an alkanol containing 1-3 carbon atoms and water, e.g. 50/50 mixture of ethanol and water.  Suitable catalysts are Raney nickel, nickel oxides, finely-divided metals of Group VIII of the Periodic Table, e.g. nickel, iron, cobalt, platinum, palladium or rhodium, Group VIII metals or copper supported on pumice, asbestos, kieselguhr, alumina, silica gel or charcoal, copper supported on palladium or platinum black, finely-divided copper, colloidal palladium or platinum and platinum sponge.  Quantities of catalyst from one part per million parts of nitro compound may be used.  The reaction preferably takes place at a temperature between the freezing and boiling point of the mixture under reaction conditions.  Pressures from 1-1000 atmospheres may be used.  The bis-(1-aminocycloalkylmethyl) amines may be separated from the reaction mixture by filtering off the catalyst and insoluble material, distilling off the solvent, and thereafter distilling the residue at reduced pressure.  The process may be carried out continuously or in combination with the process described in Specification 790,608 by which bis-(1-nitrocycloalkylmethyl) amines are prepared.  Examples are given of the preparation of bis-(1-aminocyclohexylmethyl) amine under various conditions of temperature and pressure.ALSO:Bis - (1 - aminocyclohexylmethyl) amine is used as a curing agent for epoxy resins.

Title: Novel elastomers and adhesive compositions containing them
Inventor: ENNIS ROYCE ELTON
IPC: C09J123/28
Filed: 1969-06-19
Abstract: 1,263,484. Chlorinated olefin/acid copolymers; adhesive compositions. E. I. DU PONT DE NEMOURS & CO. 19 June, 1969 [25 June, 1968], No. 31121/69. Heading C3P. Solvent-soluble elastomers comprise a chlorinated copolymer of an α-olefin and acrylic acid or an α-alkyl derivative thereof having up to 8 carbon atoms, which has a chlorine content of from 15-45% by weight (but excluding chlorinated ethylene-acrylic acid copolymers), the base polymer (i.e. non-chlorinated form) containing from 0À15-0À85 mole per cent of the acid monomer units and having a melt index of 0À1-20. Ethylene is preferred as the α-olefin component; propylene is also useful. The substituted acrylic acid may be α-ethylacrylic or α-propylacrylic acid but methacrylic acid is preferred. The elastomers can be prepared by chlorinating the base polymer, or by copolymerizing the acid monomer with a chloro-olefin such as vinyl chloride. In the example an ethylene-methacrylic acid copolymer is reacted with chlorine in carbon tetrachloride/chloroform using azodiisobutyronitrile as a catalyst for the reaction. The elastomers can be used to form adhesive compositions by dissolving the elastomer in an organic solvent therefor together with sufficient water and an alcohol (C 1 -C 4 ) to prevent a large increase in viscosity. A basic adjuvant (e.g. an amine or metal oxide, hydroxide or salt) capable of reacting with the carboxyl groups of the elastomer may optionally be present; magnesium oxide is a preferred adjuvant. Suitable solvents for the elastomers include hexane, heptane, octane, benzene, toluene, xylene, methyl ethyl ketone, methyl isobutyl ketone, diethyl ketone, ethyl acetate, methyl acetate and mixtures thereof.

Abstract: 1,071,961. Shaping metal foil receptacles. REYNOLDS METALS CO. Aug. 4, 1964 [July 31, 1963], No. 31345/64. Heading B6J. [Also in Divisions B3 and B8] A sheet (46), Fig. 7, of metal foil is embossed by means of upper and lower dies 47, 48 respectively, to form a receptacle (32), Fig. 4, having a flange strengthened by a peripheral channel and bead (39). Members 67 and 90 of the lower die are fixed. The upper die 47 is lowered, taking with it rings 77, 71 and 86 of the lower die, and cutting out a circular blank as an upper ring 63 passes the ring 90. Ring 54 of the upper die and ring 71 of the lower die are halted by the shoulder 75 of member 67. After further movement, the ring 77 is arrested by a shoulder 79 of the now stationary ring 71, the ring 54 being moved relative to upper die member 49 against the action of a spring (61), Fig. 9, thus forming the channel in the receptacle flange. The ring 63 continues down with the lower ring 86 thereby drawing the foil into co-operating bead-forming portions of these members. The rings 63 and 86 then rise, by fluid pressure acting on the ring 86, to complete the bead (39). The die member 49 is also raised, the ring 54 being temporarily held by the stepped part (42), Fig. 11, of the receptacle, against the action of the spring (61). The lower die members are halted when a flange 72 on the ring 71 engages a shoulder 74 on the fixed member 67. Thereafter, the upper die member 49 and ring 63 rise from the lower die, enabling the spring (61) to act on the ring 54 to eject the finished receptacle.

Title: Improvements relating to clamping and cutting mechanism for circular knitting machines
IPC: D04B9/26
Filed: 1939-12-08
Abstract: 533,879. Knitting - machines. SCOTT & WILLIAMS, Inc. Dec. 8, 1939, No. 31813. Convention date, Dec. 23, 1938. [Class 74 (ii)] Relates to means for automatically gathering, clamping and cutting wrap yarns in a circular knitting machine and returning them to position for the wrap yarn fingers to reintroduce the yarns. The gathering &c. keeps the space inside the cylinder clear for bights of other yarn to sweep round the knitting area without becoming entangled with inactive wrap yarns. The invention is described in connection with a machine for knitting half hose with elastic tops. The clamping means is located in the middle of 'the needle cylinder below the wrap hand and is moved vertically by the pattern mechanism to carry out the necessary manipulations of the wrap yarns. Revolubly mounted inside a central shaft is a clamp tube 126 on the lower end of which is a clamp plate 127. Inside the tube 126 is a rod 128 which is revoluble with relation to the tube. A disc 129 and a spiral 130 are fixed to the end of the rod. In order that it may gather the yarns to be clamped, the outer end of the spiral extends outwards to a point radially beyond the operating edge 32 of a separator 30. The wrap yarn fingers 766 are above the separator so that the wrap yarns Y pass radially inside the edge 32 and contact with the edge of the plate 129. If the spiral be kept stationary relatively to the wrap yarn fingers, each of the wrap yarns in turn is caught in the opening 132. To clamp the yarns the parts 127, 130 are pressed together. The parts are lifted to clamping position by a pattern-controlled arm 185 acting on a spring-pressed collar 190. A stop 196 limits the upward movement of the rod 128 and separates the spiral and clamp. When the arm 185 is raised the upward end 184 engages a collar 193 and stops the rotation of the rod 128 and spiral. An intermediate stop 199 is used in connection with the release of the wrap-stripe yarns after patterning begins. The rotary motion of the clamp tube is transmitted to the spiral 130, except when gathering wrap yarns by means of four radial pins 145 one of which is engageable by a vertical pin 146 on the spiral. When the spiral and clamp are separated to gather the yarns the pin 146 clears the radial pins 145. The cutter blade 204 is pivoted to a lever 200 and is engaged by a pin 206 when in idle position. Specifications 12722/13, [Class 74 (ii)], 362,899, 362,916 and 383,840 are referred to.

Abstract: 894,277. Semi-conductor devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 16, 1960 [Sept. 19, 1959], No. 31943/60. Class 37. A layer containing aluminium is formed in a body comprising silicon by heating the body in contact with alumina to cause diffusion of aluminium therefrom into the body. The heating may be carried out in hydrogen, inert gas, or vacuum. In an example a number of 1 ohm cm. N-type silicon bodies 5 are embedded in powdered alumina mixed with 1 % by weight of pure powdered silicon in molybdenum container 4 in a quartz tube 1. The silicon bodies are then raised to 1200‹ C. for an hour by high-frequency heating of the molybdenum tube 2 while a stream of dry hydrogen flows through the tube. The powdered silicon counteracts evaporation of the surface of the silicon bodies. After cooling, the bodies, which now have a P-type surface layer 6, 12 to 15 Á thick, may be fabricated into transistors, diodes, or photo-electric cells. In an alternative method one of the slower diffusing donor impurities antimony, arsenic and phosphorus in the form of oxide is added to the alumina. Simultaneous diffusion of the aluminium and donor in this case produce a P- layer overlain by an N-layer.
