  • Nozzles for pyrophoric IR decoy flares
    Patent number: 5866840
    Abstract: A decoy flare for infrared (IR) seeking missiles comprises a tubular shell with a cover member hermetically sealed to an outer front edge of the tubular shell to form a container for a pyrophoric liquid. The cover member has a central rupturing disc that ruptures at a predetermined pressure, a nozzle cap with a nozzle opening being attached to the cover member adjacent an exterior surface of that rupturing disc. Pressure applied by a mechanism to the pyrophoric liquid can rupture the rupturing disc and eject the pyrophoric liquid through the nozzle. A pre-heating chamber formed by an enclosure surrounds the nozzle opening in order to provide for more reliable ignition of the pyrophoric liquid at high altitudes and low flow rates, that enclosure having an outer surface containing a number of perforations through which air can enter the pre-heating chamber and through which pyrophoric liquid can be ejected from the chamber into the atmosphere.

  • XDM pyrophoric countermeasure flare
    Patent number: 5631441
    Abstract: A decoy flare for infrared (IR) seeking missiles comprises a tubular outer shell with a first rupturing disc sealing a rear end of the outer shell and a cover member with a second rupturing disc sealing a front end of the outer shell. These form a sealed container for a pyrophoric liquid. A nozzle cap is attached to the cover member with a nozzle being located in front of the second rupturing disc. A piston in the container adjacent the first rupturing disc separates the pyrophoric liquid from the disc. A holder for a gas generator, a disc of energetic material, is connected in sealed relationship to the container to position the gas generator adjacent the first rupturing disc and form a gas generating chamber between the holder and that disc. That holder contains an ignition mechanism for the gas generator and a seal to prevent gases from escaping via the ignition mechanism after it is activated.

  • Method and assembly for igniting a burner assembly
    Patent number: 5832999
    Abstract: A method and assembly for igniting a burner using a pyrophoric liquid. A quantity of pyrophoric liquid is first transported from a container to a slug launching chamber and then transporting into a fuel gas stream for the burner. The slug launching chamber is flushed with a hydrocarbon liquid to remove any of the quantity of pyrophoric liquid from the launching chamber, while the assembly can be purged with an inert gas prior to removing the pyrophoric liquid container and replacing it with a new container.

  • SYSTEM AND METHOD FOR DELIVERY OF PRECURSOR MATERIAL
    Publication number: 20090263257
    Abstract: The present invention relates to a method for distributing products, in particular pyrophoric, from a storage point to a use point. According to the invention, an inert gas is bubbled through the product, in particular pyrophoric, to be purified in the liquid state in order to generate a mixture, the mixture is preferably routed close to the use point, the product, in particular pyrophoric, is separated from the inert gas and from some light impurities, to generate a purified final product, in particular pyrophoric, in liquid or solid form. The purified product is supplied in a quantity just necessary to the use point, particularly when it is solidified in the heat exchanger after the transport of the mixture.

  • Method and apparatus for ignition of downhole gas generator
    Patent number: 5163511
    Abstract: A downhole gas generator can be ignited downhole by an ignitor mixture combining with an oxidant. The ignitor mixture is provided by an ignitor subsystem. In one embodiment, the ignitor subsystem bubbles gaseous fuel through a chamber of liquid pyrophoric. The chamber is heated, wherein the fuel obtains a vapor content of the pyrophoric, forming a gaseous ignitor mixture. In another embodiment, gaseous fuel is turbulently injected into a chamber. Liquid pyrophoric enters the chamber through an orifice. The fuel passes through a nozzle wherein its pressure is reduced. This pressure drop is imposed on the pyrophoric, wherein the pyrophoric is drawn into the chamber. The fuel mixes with and atomizes the pyrophoric to form an ignitor mixture.

  • Pyrophoric flame composition
    Patent number: 4230509
    Abstract: A low viscosity liquid pyrophoric composition, which provides good safety der ordinary handling conditions but ignites rapidly when disseminated into the atmosphere, consists essentially of about from 50% to 85% by weight of a homogeneous solution of polyisobutylene in triethylaluminum and about from 15 to 50% of a saturated aliphatic hydrocarbon of 5 to 12 carbon atoms, said composition having a viscosity ranging about from 30 to 150 centistokes at 40.degree. C. When explosively disseminated into the atmosphere, the composition generates a fireball having a controlled ignition delay, which permits essentially complete vaporization of the hydrocarbon prior to ignition of the TEA, thereby producing rapid pulses of intense thermal radiation having a temperature as high as 1200.degree. C. (2192.degree. F.) and higher.

  • Production of metallic powders
    Patent number: 4191557
    Abstract: The process of producing a metallic powder from a metal compound such as nickel chloride comprising the steps of: first forming a slurry of (1) a compatible, non-aqueous liquid in which the metal compound is completely or partially soluble, and (2) a reactive metal which occupies a position in the electromotive series above the position of the metal constituent in the metal compound, i.e. has a single electrode potential more negative than that of the metal constituent in the metal compound. The metal compound is then added to the solvent in the slurry, e.g. forming a slurry of pyrophoric aluminum powder in methyl ethyl ketone (MEK) and then adding nickel chloride to the MEK. The reactive metal can be in a pyrophoric state prior to introduction of the metal compound, or it can be made to be pyrophoric in the presence of the metal compound, so that it reduces the metal constituent of the dissolved metal compound as metal compound solution contacts the pyrophoric metal surface.
