Abstract: A spark igniter for gas burners includes a gas collector having a passage extending between open front and rear ends. The open front end is substantially larger than the open rear end, and is positionable adjacent a gas burner for receiving gas therefrom. Gas flows into the open front end of the collector and mixes with air to form a combustible mixture. A spark igniter mounted within the gas collector passage ignites the mixture to produce a flame for igniting the gas burner. The gas collector is metal and forms the ground electrode for the spark igniter, and has an integral mounting bracket thereon.

Abstract: A flame cutting machine includes an ignition system for igniting the fuel gas which is connected by a transverse bore to a longitudinal bore parallel to the blend canal of the machine.

Abstract: The high voltage transformer for the ignition system of an oil burner and the control system for the oil burner are packaged together in a single housing. The duty cycle of the transformer is discontinuous. The transformer core is of symmetric U-I configuration but the coil arrangement is asymmetric with a single primary coil being provided. The transformer is not potted, the core ends are free of coils, and one core end overlaps a circuit board for the control system to thereby foreshorten the overall package. Although the transformer is not potted, tight constraints against shorting of the high voltage secondary leads are maintained by provision of an insulator bushing means which is positioned in apposition to the transformer secondary coils by means of a bracket which also provides a mounting for the transformer core, the high voltage leads being drawn through the insulator bushing means and secured at terminal contacts at the lower ends of the bushing means.

Abstract: An ignition torch for a gas turbine comprising a cylindrical body which is closed at one end and open at another end. Fuel and air are separately fed into the cylindrical body and mixed with each other therein by an appropriate means to give a uniform fuel-air mixture near the open end of the cylindrical body. The mixture is electrically ignited to continuously emit a stable torch flame.

Abstract: An electric gas ignitor is disclosed having a gas igniting fiber comprising a core of conductive refractory material and an outer, high strength, oxidation resistant coating. One aspect of the invention concerns a primary current path defined by at least a portion of the fiber core and comprising a material having a highly uniform resistance per unit length. A substantially uniform temperature distribution is thereby promoted on the fiber surface and the formation of localized "hot spots" is inhibited. The primary current path is preferably an anisotropic material having a preferred crystal orientation which uniformly conducts electricity along the fiber length.A second aspect of the invention is directed to the inclusion of a diffusion-barrier material between the fiber core and the oxidation-resistant coating to prevent diffusion of the core and coating, which changes the fiber operating temperature and decreases its operating life.

Abstract: A pilot assembly for a furnace burner includes a housing having a first port capable of mating with a flame detector which can monitor the pilot or main flame of the furnace burner. The housing further includes an air-fuel mixture inlet port coaxially disposed with respect to a second port, which serves the purpose of mating with a spark ignition means. The axes of the fuel mixture inlet port and second port are substantially perpendicular to the axis of the first port. The second port is adapted such that any portion of the spark ignition means extending through the second port and into the housing will not interfere with the monitoring performed by the flame detector means. The housing further includes a third port which can accommodate means for visually sighting the pilot flame. The third port can also serve the purpose of providing manual ignition of the pilot burner.

Abstract: A grill for cooking has a gas burner, a gas igniter adjacent that burner, and a piezo electric spark source. The grill has a metal casting; and the igniter has a bracket that mechanically secures and electrically connects that igniter to that casting, and also constitutes one arcing contact of that igniter. One contact of the spark source is electrically connected to the casting; and a wire connects the other contact of that spark source to a second arcing contact of the igniter. A shielding portion of the igniter overlies the confronting ends of the arcing contacts to keep fat, meat juices and other drippings from engaging those confronting ends.

Abstract: A start flame igniter of the combustion chamber of a gas-turbine engine has a housing with an injector for spraying fuel supplied to a combustion chamber of the igniter. Located inside the igniter housing are a spark plug in such a way that a discharge zone of the spark plug contacts the fuel sprayed by the injector and a cylindrical bushing which is coaxial to the spark plug and partially embraces said spark plug at the side where the spark plug discharge zone is situated. The length of the bushing is sufficient to ensure a direct contact with the fuel sprayed by injector at a minimum cone of the fuel spray relative to the operation duty of the injector. The bushing butt facing the sprayed fuel has an inclination which coincides approximately with a generatrix of the minimum cone of the fuel spray. The bushing butt is provided with a plate following the shape of a half of butt nearest to the injector. The plate along the axis has a recess embracing the discharge zone of the spark plug.

Abstract: An igniter for acetylene torches having ignition means protectively housed in a box-like metal enclosure that has an inwardly depressible hinged wall, depression of which activates the ignition means. A guarded opening through the depressible hinged wall provides a passageway through which gas issuing from a torch may be projected into the vicinity of the ignition means, so that by positioning the nozzle of the torch to project the jet of gas issuing therefrom into the inlet of the guarded opening and, at the same time, applying inward pressure on the hinged wall, the torch is ignited. Located within the enclosure are two solenoid-actuated valves which control the admission of gas and oxygen to the torch, and an upwardly biased depressible torch supporting hook on the exterior of the enclosure holds a normally closed switch that controls energization of the solenoids of the valves, in its open condition as long as the torch is supported by said hook.

Abstract: A device having a two piece housing on the cover of which are mounted the electrical components of an arc producing circuit including a sparkplug projecting upwardly through the cover.

The system is adapted to accommodate heavier and lighter than air combustible gases.

Abstract: A main burner oil gun in which hard to ignite liquid fuels can be burned, including an ignition means for the oil gun which will reliably light the oil gun time after time. The oil is sprayed from the oil gun tip in the shape of a hollow cone. Air is introduced surrounding the oil gun, and flows over a baffle plate located transversely of the oil gun, creating eddies of air, some of which break through the curtain of fuel issuing from the tip in a conical shape. This current of air that breaks through the fuel carries some fine droplets of fuel along with it, and forms a recirculation zone extending back to the oil gun tip. The ignition means is located within the hollow conical fuel flow, along the inner edge of the recirculation zone, so that the initial flame established is carried back to a point directly in front of the oil gun tip.

Abstract: A combustion chamber is provided with a fuel source and an igniter for initiating combustion. The igniter projects into the combustion chamber and into proximity with the fuel source. A heated tip portion of the igniter initiates burning and is cooled by means of cooling air passing through a plurality of air passages defined by a plurality of channels near the external surface of the igniter housing and further defined by a surrounding ferrule. Certain of the channels extend axially of the housing while at least one channel extends circumferentially thereabout and intersects the former channels. An opening in the ferrule provides communication between preselected of the channels and the interior of the combustion chamber.

Abstract: A liquid fuel burning heater for use in vehicles comprising a burner unit enclosed within a burner housing which in turn is surrounded by the heater housing. A lateral head extending from the heater housing encloses within a hermetically sealed space the connecting end of the ignition plug, a duct leading from this head space either to the atmosphere outside the vehicle, or to the intake side of the burner unit, thereby evacuating leaked exhaust gases.

Abstract: A gas diffuser screen surrounding a pilot burner and with one of the perforated walls of the screen slanted outwardly at an angle approximately forty-five degrees from the vertical and overlying an electrode spark igniter to ignite the gas supplied to the burner. The slanted wall forms a pocket of gas beneath the wall thereby permitting greater latitutde in placement in any direction of the electrode igniter outside the screen with respect to the pilot burner without adversely affecting the spark ignition of the gas supplied to the pilot burner.
