A further embodiment (Fig. 2, not shown) again has the extra plies 21 but also has two further extra plies which are similar to the plies 21 except that their radially inner regions are disposed between two carcass plies. In another embodiment (Fig. 3, not shown) two extra plies (27) are provided which each begin at a point axially outward of the associated beadwire and follow a sinuous path in cross-section, the radially inner regions of these extra plies being disposed between the carcass plies. The extra plies may, if there is more than one carcass ply, be extensions of one of the carcass plies rather than being separate from the carcass plies as shown. The carcass cords may be elastic and in this case the calendering elastomer of the carcass ply or plies may have a lower modulus of elasticity than that of the extra plies, the moduli respectively being, e.g. 115 g./mm<SP>2</SP>. and 400 g./mm.<SP>2</SP> (at 100% elongation). The cords of the extra plies may differ from those of the carcass ply or plies with regard to material, structure or disposition, e.g. the cords of the extra plies may be disposed at up to 45 degrees to the circumferential direction. The cords of the extra plies and the carcass ply or plies may each comprise three, 1680 denier, strands of polyamide. The tyre may have a breaker assembly composed of steel cord plies 16-19, and there may be a stiffening strip 30 in each bead region consisting of metal cords inclined at 30 degrees to the circumferential direction.

Title: Improvements in and relating to Powder Spray Apparatus.
Inventor: WEBB JOHN
IPC: B05B7/14
Filed: 1965-11-19
Abstract: 1,172,824. Spray-producers. AEROSTYLE Ltd. 16 Feb., 1967 [19 Nov., 1965], No. 49251/65. Heading B2F. [Also in Division B8] Powder is supplied to a spray gun by apparatus comprising an air-tight - container- 1 containing an endless belt 6 partially immersed in powder and adapted to register in succession a plurality of holes 30 therein containing powder with the inlet end of a discharge conduit 31, the air in the container being under pressure so that the powder is blown out of each hole and into the conduit 31. The belt is mounted on pulleys 7, 9, the pulley 7 being rotated by a motor 13 via a shaft 8. Air is introduced via conduits 25 into the bearing 11 of the shaft 8 to prevent fouling with powder. The shaft 10 of the pulley 9 may be provided with a similar bearing. The belt is provided with teeth (29), Fig. 2 (not shown), which engage recesses in the pulleys. A nut 30a prevents air being blown directly into the conduit 31. The pulley 9 preferably comprises a plurality of spaced rings 33 to prevent packing of the powder. A flexible diaphragm 37 forming the base of the container may be vibrated at an adjustable rate by a motor 39 having an eccentrically loaded shaft. The diaphragm itself is eccentrically loaded by a weight 42. Air fluidization through a perforated plate forming the base of the container may alternatively be used to prevent packing of the powder. In a modification the rotary disc of Specification 1096683 is replaced by an endless belt and the powder is blown from the holes therein by air from a nozzle located within the container. The powder may be heated and may be deposited electrostatically.

Title: Gas turbinen engine with facilities for blowing through the fuel injector
IPC: F02C7/232
Filed: 1969-10-08
Abstract: 1,250,033. Liquid spray burners. MOTORENUND TURBINEN-UNION MUNCHEN G.m.b.H. 8 Oct., 1969 [8 Oct., 1968], No. 49532/68. Heading F4T. [Also in Division F1] A gas turbine engine comprises a compressor 1, combustion equipment 4 having a fuel injector 9, a turbine 3 driving the compressor through shaft 2, an air preheater 5, and apparatus oper. able during shut-down of the engine to blow through the injector with a gas at a temperature substantially lower than that of the preheated air supplied to the combustion equipment so as to tend to prevent a build-up of fuel deposits in the injector. In Fig. 2 the fuel injector comprises a fuel supply device 15 to which fuel is supplied through inlet 20 and duct 30 and issues through ports 34 and 18 into the combustion chamber. Air under pressure from the air preheater 5 enters the casing 16 through inlet 16a and passes through passage .17 to discharge through port 18. A control device 19 is associated with the fuel injector and comprises a piston 24 disposed in cylinder 22, the piston being urged by spring 26 against stop 33. When fuel is supplied through inlet 20 the fuel acts on the small diameter portion 23 of the piston. As the piston moves upwardly the pressure acts on the full area of the piston which moves past the duct 30 so that fuel now passes to the injector 9; as the piston moves upwardly the valve member 31 carried by the piston closes off the port 32. When the engine is shut-down, the fuel supply is shut-off and the piston 28 is moved downwardly by the spring 26 and the valve 31 moves away from the port 32. Air from the compressor is passed through the passage 12 thus by-passing the air preheater and flows through inlet 16a and acts to blow any remaining fuel back through the injector 15, through the duct 30 and port 32 to atmosphere. In Fig. 3 the control .unit comprises a piston 38 similar to the piston 24 of Fig. 2, the piston carrying a ball valve 43<SP>1</SP> on a tappet 43, the ball valve closing off port 44 when the piston is in its upper position when fuel is flowing to the injector 9. When the fuel is shutoff the piston is moved downwardly so that the port 44 and passage 30<SP>1</SP> are opened. Air under pressure taken from the compressed air braking system of a vehicle in which the engine is mounted now flows through line 45 port 44 and passage 30<SP>1</SP> to blow any fuel remaining in the injector into the combustion chamber.
Patent GB-499698-A (GB)
Abstract: 499,698. Thermally - actuated valves. SYLVEN, G. April 11, 1938, Nos. 11056 and 11057. Convention dates, July 21, 1937 and Jan. 25, 1938. [Class 135] In gas cookers, stoves, &c. comprising main and ignition burners, a thermo-sensitive element heated at least by the ignition burner and actuating a control valve between the main gas supply and the ignition burner, a manuallyoperated control valve, and a byepass conduit between the main supply and the ignition burner out of control of the heat - actuated valve, the manually operated control valve opens and closes directly all gas conduits leading to the main burner and, in the closed state of the heat-actuated valve, all gas conduits leading to the ignition burner and the byepass conduit. As applied to a gas cooker, the main and auxiliary jets of a burner 3, Fig. 2, are supplied through concentric passages 8, 9 and the burner is disposed adjacent a thermo-sensitive element 13 heated also by an ignition burner 4. The thermostat comprises a bent bi-metallic strip secured centrally to a rod 16 which carries at its other end a needle valve 20, Fig. 5, controlling a gas inlet 18. The needle valve 20 operates in a chamber 19 communicating by a passage 36 with a gas valve 6 shown in the closed position in Figs. 3 and 5. A quarter turn in an anticlockwise direction brings the valve to the igniting position in which a circumferential groove 43 in the lower part of the valve bridges passages 44, 45 in the valve housing 5 to permit gas from the inlet 18 to byepass the valve 20 and reach a conduit 10 leading to the ignition burner 4. On igniting the burner, the thermo-sensitive element is heated and opens the valve 20. The valve 6 is now turned the opposite way, a passage 46 between the chamber 19 and the passage 45 maintaining the supply to the ignition burner irrespective of the position of the valve 6. In the position a quarter of a turn beyond that shown, the valve places a transverse passage 35 in line with passages 36, 37 leading to the conduit 8 for the main burners. Simultaneously, a longitudinal passage 39 leading from the transverse passage 35 in the valve conducts gas to a conduit 40 connected to the conduit 9 of the auxiliary burners. On further rotation of the valve 6, the main burners are cut off and horizontal passages 42, 41 in the valve connect the passage 36 with the passages 35, 39 in the valve to maintain the supply to the auxiliary burners. If both the burners 3, 4 are inadvertently extinguished, the thermo-sensitive element 13 cools and cuts off the supply to both by closing the valve 20. The valve 6 is locked in the position of closure by a pin 30, on a spring-pressed plunger 28 in the valve, engaging a recess in a horizontal slot in the valve housing 5.
