Title: Manufacture of a composite comprising a metal alloy and a  carbonaceous material
IPC: B23K5/00
Filed: 1972-08-08
Abstract: 1439329 Welding UNITED KINGDOM ATOMIC ENERGY AUTHORITY 8 Aug 1973 [8 Aug 1972] 36884/72 Heading B3R In making a composite body formed of a metal alloy and carbonaceous material, i.e. carbon fibres, graphite fibres, diamonds, diamond abrasive particles or refractory metal carbides, e.g. titanium or tungsten carbide, bonded to the metal alloy, the carbonaceous material is contacted with the molten metal alloy which includes a carbide forming constituent but not in sufficient quantity to allow the alloy to substantially wet or react with the carbonaceous material the alloy is allowed to solidify and then the assembly is heat treated to cause the carbide forming constituent to diffuse through the alloy and form a carbide with the carbonaceous material which bonds the alloy to the carbonaceous material. The carbonaceous material may be incorporated within the metal alloy which latter expression includes a solid solution, a compound, an intermetallic compound or combinations of these forms. Suitable carbide forming constituents are Sc, Ca, Mn, V, Zr, Cr, W, Nb, Ta, Hf and Ti and suitable parent metals of the alloy include copper, copper alloys, aluminium, aluminium alloys, lead, tin, lead-tin alloys, zinc and zinc alloys. The molten alloy is allowed to solidify before the heat treatment is commenced and the alloy is reheated or held at a temperature at which it remains solid. In an example an alloy of copper and 0À001% V or 0À01% Cr is forced under pressure into the interstices of a bundle of carbon fibres. The alloy is allowed to solidify and the assembly is then heat treated to effect diffusion for a few minutes or several hours. The molten alloy may be caused to infiltrate the interstices between loosely backed carbide particles or diamonds to produce a grinding wheel.

Title: Improvements in and relating to fluid cooling systems
IPC: F25B49/02
Filed: 1938-12-20
Abstract: 522,911. Refrigerating. BRITISH THOMSONHOUSTON CO., Ltd. Dec. 20, 1938, No. 37079. Convention date, Dec. 23, 1937. [Class 29] In fluid cooling systems utilising two compression refrigerating machines, control means are provided for selecting the driving motors for operation in accordance with the load on the system, determined by suction pressure. As shown applied to an air cooling - system, evaporators 18, 19, Fig. 1, are arranged in a duct 10 through which fresh air and used air are drawn through inlets 11, 12 with filters 13, 14 by a fan 15 and discharged through an outlet 17. The evaporators are supplied through pipe 22 and thermostatic expansion valves 36, 37 from two machines 20, 21. When there is a demand for cooling, a thermostat element 35 in the enclosure to be conditioned moves to the right energizing a coil 40 to connect the motor and control circuit across the supply lines 42 by a switch 43. Motor 32 is thereby energized through switches 45, 46 and a line 47. The switch 45 is operated by the armature 53 of a coil 48 connected across the lines 44 through a switch 49, the switches 49, 46 being operated by pressureresponsive members 52, 50 connected with the common suction line 23 of the two compressors. In its upper position the switch 45 energizes the motor 34 through a line 55 and connects a pressure-operated switch 62 in series with the motor 32. To prevent operation of the machine 21 if'the machine 20 can satisfactorily carry the load a time delay dashpot 56 is provided for delaying operation of the switch 45. If the machine 20 reduces the pressure in the suction line 23 sufficiently before the armature 53 operates the switch 45 the pressure element 52 opens the switch 49 de-energizing the coil 48 and preventing actuation of the switch 45. If the pressure in the suction line is below a predetermined value when the machine 21 is operating, the switch 62 is opened by a pressure element 63 to stop the machine 20 so that the machine 21 carries the entire load. In a modification, Fig. 2, evaporators 72, 74, in the air duct 64 are separately supplied by machines 73, 75 driven by motors 77, 86. On operation of the thermostat 94 the motor 77 is energized through switches 101, 102 responsive to the pressures in the suction pipes 84, 91 respectively and the motor 86 is energized through a switch 103 responsive to the pressure in the suction pipe 91. The switch 102 is arranged to close at. pressure substantially. higher than that at which it opens, and when the pressure in the suction line 91 falls below a predetermined value the switch 102 opens and stops the machine 73. The entire load is then carried by the machine 75 and the evaporator 74. The switch 102 may be replaced by a switch responsive to pressure in the suction line 81 adapted to operate a time delay switch in the circuit of the motor 86 so that if the load is initially sufficiently low to be carried by the machine 73 the motor 86 of the unit 75 will not be started.

Title: Method of and machine for making blown hollow articles
Inventor: STRONG BERNARD
IPC: B29C49/28
Filed: 1959-11-02
Abstract: 902,008. Blow-moulding hollow articles. SHIPTON & CO. Ltd., E. Nov. 2, 1960 [Nov. 2, 1959], No. 37156/59. Class 87(2). Lengths of downwardly extruded tube 47 are gripped by a pair of gripping members 17 below the bottom faces of extrusion nozzles 4 and carried down between the open parts of a multipart mould 6a, 6b to position the lower end of the tube over upwardly directed blowing nozzles 28. The mould is closed pinching the upper ends of the tubes and pressing the lower ends on to the blowing nozzles, and the tubes blown to conform with the inside of the mould, after which the mould is opened and the moulded article ejected. The grippers 17, which are water cooled are mounted on a transfer carriage 18 slidable up and down on bars 19 by means of a double acting air cylinder 21a, Fig. 1. The grippers 17 are opened and closed by a double acting air cylinder 26 operating through bell crank levers pivoted at 23. The movement of the transfer carriage is limited by stops 19a which allow the grippers to move from a point just below the nozzles 4 to a point just above the mould. The mould parts 6a, 6b are mounted on bolsters 7, 8, respectively. The bolster 7 and a member 12 are fixed to longitudinally slidable bars 9, while the bolster 8 is slidable on the bars. The bolster 8 and the member 12 are pivotally connected by levers 13, 14 to the piston rod 15 of a double acting air cylinder 16. Raising of 15 will cause the bolster 8 and member 12 to move apart and so the mould is closed. The blowing nozzles 28 are mounted on the upper end of a piston rod of a double acting air cylinder 31, so that in their upper position they project through bores 36, 37 in a stripper bar 35 and a water cooled tank 38. The stripper bar is slidable on bars 33 and is connected by a lostmotion connection 40, 40b, to the blowing nozzle support 29. The movement is such that the nozzles 28 are never allowed to leave the bores 36. After the mould has opened the blowing nozzles are lowered and the blown articles remain thereon bringing the stripper bar down with them until the bar 35 reaches the stops 41 when the articles are stripped from the nozzles 17. The support 29 continues its downward movement so that the nozzles retract into the bores 37 and at the bottom of its stroke it moves a pivoted lever 42 connected to an ejector bar 43 to eject the articles to a shoot 57. The machine can be controlled manually or by an automatic mechanism using trip switches 50 ... 56 operated by movement of the various machine parts and time switches (not shown). This mechanism includes devices to prevent the mould being closed until the blowing nozzles are in the raised position and to prevent the mould being opened while the blowing air is still applied. The gripper plates 17 have chamfered edges and are held closed below the nozzles 4 for a short time determined by a time switch. The resulting build-up of pressure in the nozzles ensures that the ends of the tubes remain fully open.
