摘要： 686,496. Sparking plugs. GENERAL MOTORS CORPORATION. Feb. 19, 1951 [Feb. 28, 1950], No. 3922/51. Class 7 (iv). In an igniter plug for a gas turbine engine comprising a casing 2, Fig. 1, haying an aperture 10. ,in its wall and an insulator 4, Fig. 2; with a centrally disposed electrode 32 mounted in the casing, the casing and insulator are arranged in spaced relationship along a part of the length of the plug to form an air duct 52 in Communication with the aperture 10 and having converging wall portions adjacent the end thereof to provide a restricted outlet 56, adjacent the spark gap, from the air duct 52; the casing may be cylindrical and have a plurality of inturned tapered electrodes 13, Fig, 1, as well as embodying a mounting flange 6. The insulator 4, Fig. 2, has a enlarged part 18 forming two shoulders 20 and 22 by which it is secured in the plug casing through a connector 14, gaskets being interposed between the shoulders and the casing, the upper one of which is in contact with the lower edge of the connector 14. The upper portion of the insulator 4 is recessed at 30 to accommodate the ignition' lead, not shown, whilst the lower part of the insulation is tapered and spaced from the casing by the cooling air duct 52, which duct communicates at the active end of the plug with the spark gap and at an intermediate point with the radial inlet aperture 10. The centre electrode 32, Fig. 2, has a knurled part 38 engaging the bore in the insulator 4, the lower surface of which is recessed at 34 for cooling purposes; the electrode 32 is connected with a terminal 42 in the upper insulator recess 30 by a conductive element 44. In a modification, the plug casing is formed in two parts which are joined together just above the upper insulator shoulder.

摘要： 695,302. Sparking plugs. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 22, 1950 [Nov. 30. 19491, No. 28559/50. Class. 7 (iv) [Also in Group XI] An electric-ignition device for combustion apparatus to which a pressure fluid is supplied during normal operation and discontinued when the apparatus is shut down e.g. a gas turbine, comprises a cylindrical body portion 6 having one open end and a central aperture 7a in its other end, means e.g. apertured flanges 7 for removably securing the body portion to a wall of a combustion chamber, a cylindrical piston member 9 axially slidable within the body portion, the piston including a skirt portion 17 and an end member including a protrusion 10 adapted to extend through the aperture 7a, ignitor and an end member including a protrusion 10 adapted to extend through the aperture 7a, ignitor means 15 including first and second insulated electrode assemblies 15b, 15a connected by telescoping electrodes 23, 24, an end cap 8 for the open end of the body portion 6 and having a central opening adapted to house the first electrode assembly 15b, the protrusion 10 on the piston end having a longitudinal opening 19, adapted to house the second electrode assembly 15a, this assembly having an outwardly extending electrode 40 defining an ignitor point 11, resilient means 22 for normally biasing the piston member 9 to an axially extended position so that the protrusion 10 and the ignitor point are located in the combustion chamber, the body 6 being adapted to be secured to the combustion apparatus with the protrusion 10 subjected to pressure within the combustion chamber for automatically forcing the piston 9 into the body portion 6, whereby the protrusion 10 and ignitor point 11 are withdrawn from the combustion chamber during normal operation of the apparatus after a self sustaining combustion has been initiated.' A second ignitor point 11 is carried directly by the protrusion 10. Three flat surfaces 10a are provided on the protrusion 10 and when shoulders 21 at the upper ends of the flats 10a clear the aperture 7a. gas pressure can act on the whole base area of the piston 9. The result is that the protrusion 10 is first withdrawn slowly since gas pressure can only act on its comparatively small cross-sectional area and after the shoulders 21 have cleared the aperture 7a it is rapidly retracted. Atmospheric pressure is maintained above the piston by the provision of apertures 16 in the cap 8.

摘要： 620,805. Lighting burners. PARSONS & CO., Ltd., C. A., and JEFFERSON, J. L. Jan. 24, 1947, No. 2304. [Class 75(iii)] A low-tension arc igniter, particularly for a combustion chamber of a gas turbine, comprises a central electrode 5 of steel or other material of high electrical conductivity, sliding in an insulating bush 4 in a tubular conductor 3 of steel or other suitable material, the electrode 5 having an insulating handle 7 through which passes a flexible connection 8 to the electricity supply. The igniter is operated by bringing the electrode 5 into contact with a projection on the end of the tube 3 by pushing in the handle 7 against the pressure of a spring 11, which, on releasing the handle 7, moves the latter quickly outwards to cause sparking between the said projection and the electrode 5. The body 3 may be mounted in a tubular guide attached to the shell of the combustion chamber so that after ignition has been effected the igniter may be withdrawn out of the combustion space.
