Abstract: 963,392. Protecting aircraft tyres. DUNLOP RUBBER CO. Ltd. Jan. 10, 1961 [Jan. 26, 1960], No. 2742/60. Heading B7C. Tubeless aircraft-wheel tyres are protected from blow-out under braking heat by means of a bush 4 sealed to a hole in the wheel rim base 2 and containing a slidable plunger 11 which is air-tightly sealed in the bush by a rubber disc 12 and is retained therein by a plug 8 of fusible metal designed to melt rapidly at a predetermined temperature, preferably slightly higher than that likely to cause tyre failure, so that the plunger 11 is expelled from the bush by the inflation pressure of the tyre, taking with it the portion of the plug 8 blocking the bush passage, to deflate the tyre. As shown, the bush has a hexagon head 5 and a screw-threaded shank to screw into the rim base from outside the tyre. The bush is bored to provide intercommunicating axial bores 6, 7 of different diameters, the larger bore 7 nearer the head 5 being screw-threaded to receive the fusible metal plug 8 and the smaller bore 6 housing the plunger 11 sealed therein by the disc 12. In alternative arrangements the bush head 5 may be adjacent the smaller plunger-housing bore 6, the bush being screwed into the rim with the head inside the tyre space, or the fusible plug may take the form of a rod passing through holes in the plunger 11 and bush wall, or the form of a circlip engaging a necked portion of the plunger and a step in the bush bore. Alternatively, the fusible plug may be slidably retained in the larger bore by a member force-fitted therewithin.

Title: Improvements relating to polishing or like apparatus suitable for operating on the bores of tubes or on other articles
IPC: B24B33/08
Filed: 1959-01-27
Abstract: 873,133. Valves. CHAFFEY, S. J. Jan. 27, 1960 [Jan. 27, 1959], No. 2836/59. Class 135. [Also in Group XXIII] Polishing or like apparatus comprises a hollow member adapted to be connected to a pressure fluid supply source and adapted to have secured thereto in a removable manner a polishing or like unit provided with pressure fluid-operated cutting elements, the hollow member incorporating a valve which is biased into a closed position to prevent the passage of the pressure fluid through the hollow member to the polishing or like unit and which valve is adapted to be opened by the pressure fluid from the supply source operating against the bias to permit passage of the pressure fluid to the polishing or like unit to operate the cutting elements of the unit. A polishing tool 10 is secured by an adaptor 13 to a hollow driving spindle 17. A piston 19 is movable in a chamber 20 in the spindle 17, a spring 34 being interposed between the piston 19 and an end face 36 of the adaptor 13. The piston 19 is formed with a seat for the head 27 of a valve, the stem of which has a part 28 passing through a duct 26 in the piston 19 and a part 29 guided in a bore 30 in the adaptor 13. A spring 31 is interposed between the piston 19 and a stop peg 32 extending through an enlarged diameter portion 33 of the valve stem. The valve is thus closed when the piston 19 is in its upper position. When fluid pressure is admitted to the interior of the spindle 17, the piston 19 is moved towards the adaptor 13; eventually the portion 33 abuts the face 36 of the adaptor whereafter the valve is opened by further movement of the piston 19 which movement is limited by abutment of the piston 19 with the adaptor 13. The fluid then passes through the duct 26 in the piston 19 and through ducts 37 in the adaptor 13 to the interior 38 of the tool 10 and moves the working elements 49 outwardly into contact with the wall of the workpiece. When the fluid pressure is reduced or cut off the spring 34 moves the piston 19 away from the adaptor 13 allowing the spring 31 to shut the valve. The continued movement of the piston 19 away from the adaptor 13 reduces the pressure in the interior 38 allowing the working elements 49 to move inwardly out of contact with the wall of the workpiece so that the tool can be withdrawn axially without scoring or flaring the end of the workpiece. The tool is substantially the same as that described in Specification 873,132 [Group XXIII].

Abstract: 1535833 Infra-red decoys SOC E LACROIX 26 Jan 1976 [29 Jan 1975] 02852/76 Heading F3A A decoy 30 for diverting an infra-red guided missile from a ship or like target having a relatively large surface area and low temperature compared with e.g. an aeroplane, comprises a water-tight ease 32 provided with floats 40, a core 66 of a pyrotechnic composition having a sufficiently high calorific effect, a liquid aerosol 64 and means for controlling ignition of the core. The calorific energy provided by ignition of the pyrotechnic core is diluted in a large volume cloud of fine droplets so that the dominant factor of the infra-red spectrum is at a wavelength of 8 to 14Á. To prolong the protection and to simulate a moving ship a plurality of decoys may be spread, preferably in a straight line, and set off in sequence. To this end the decoys 30 may be launched in sequence from a rocket 18 (Fig. 2) about which they are arranged in cells 28 formed by radial fins 22 and transverse partitions 24. Preferably the rocket rotates on its axis and a timing device triggers the ejection of a decoy 30 each revolution, suitably vertically downwards. The decoy illustrated in Fig. 3 is ejected by ignition of pyrotechnic charge 48 either electrically or by pyrotechnic band 52. Ejection triggers electronic timing circuit whereby after a set time primer 70 is ignited and thereafter composition 66, which may be aluminium or boron powder and potassium perchlorate. Aerosol 64 may be titanium or tin tetrachloride. Preferably cover 60 of the container for the pyrotechnic composition breaks instantaneously on ignition, whereas cover 58 of the aerosol container is constructed so that it undergoes some elongation first.

Title: Improvements in or relating to electric surface-heating units adapted to support cooking vessels or the like
IPC: F24C15/10
Filed: 1954-02-01
Abstract: 746,911. Electric hot plates. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Feb. 1, 1954 [Feb. 4, 1953], No. 2892/54. Class 39(3). An electric heater for cooking vessels comprises a tubular sheathed element 14 supported on a spider and wound in a spiral having at its centre a metal disc member 44. A thermistor 42 is mounted beneath and in good thermal relation with the disc 44, and, with control means (not shown), serves to regulate heating of the element 14. A cup shaped member 38, which may be of copper, aluminium or one of their alloys, forms a heat shield between the element 14 and the thermistor. With no vessel on the heater, the disc member 44 and the cup heat shield are urged upwardly above the upper surface of the element 14 by springs 57, 59. Placing a vessel on the heater causes the disc 44, the flange 41 of the heat shield and the upper surface of the element 14 to make good thermal contact with the bottom of the vessel, slight fitting of the disc and shield being possible to allow for any unevenness of the bottom of the vessel. Stray heat from the element 14 in the direction of the thermistor is absorbed through the outer edge of the flange 41 and the surface of the tubular wall 40 of the shield and is conducted to the vessel through the top surface of the flange. A drip sleeve 66 and an annular membrane 61 of heat insulating material, e.g. polymerized silicone rubber, protect the thermistor from spillage. A reflector is provided, Fig. 2 (not shown). In a modification, Fig. 6 (not shown), the annular membrane is dispensed with, the metal disc member sliding in a vertical bore of an insulating annular member with a minimum of side play. Specification 746,796, [Group XXXV], is referred to.

Abstract: 563,234. Making grid electrodes. STANDARD TELEPHONES & CABLES, Ltd. Feb. 26, 1943, No. 3163. Convention date, April 7, 1942. [Classes 83 (ii) and 83 (iv)] . Welding; knurling.-A grid electrode for an electric - discharge device is made by embossing the surface of the support wire with a number of parallel closelyspaced, and preferably longitudinal, grooves with intermediate ridges tapering to knife edges, placing the grid wire in contact with the knife edged parts, passing a welding current between the parts and pressing them into engagement with each other to complete the weld. By grooving the large diameter support wire an excessive heating of the relatively small grid wire during welding is prevented while obtaining an effective weld. The support wires and preferably also the grid wires may be made of a metal of high melting point, such as molybdenum, tungsten or nickel. The support wires 2 are provided with grooves with knife-edged ridges 14, the spacing between which is small relatively to the diameter of the grid wire 3, by passing them between a pair of hand-driven grooved rollers in one of which the groove is provided with a number of V-shaped cutting edges 12.
