Abstract: A flat electric match includes a substrate having a surface. A first electrical lead and a second electrical lead each having an end, are carried by the substrate on the surface. The ends of the electrical leads are spaced apart on the surface. A bridge wire is coupled between the ends of the electrical leads and carried by the substrate on the surface. A pyrotechnic material is carried by the substrate on the surface, with at least a portion of the pyrotechnic material contacting the bridge wire.

Abstract: The method of precoating surfaces to be brazed without the use of corrosive flux by the application of a mixture of silver particulates, binder and solvent followed by solvent evaporation and heating for depolymerization of the binder. The heating results in a silver film formed on the surface prior to brazing.

Abstract: Demonstration apparatus for showing the process of vapor phase deposition and extractive metallurgy is disclosed wherein a vacuum vessel is provided with an inner vessel containing a resistive heater and source material. A condenser is utilized to promote deposition of material on the inner vessel in a controlled manner. A furnace containing a resistive heater and the source material is supported in the inner vessel.

Abstract: This application relates to the art of pyrotechnics and specifically concerns an improvement in the process for preparing granulated pyrotechnic compositions.

Abstract: This invention relates to propellants and in particular to a method for safely forming a binary propellant.More specifically, this invention relates to a method for safely forming a Binary Propellant useful as a propellant replacement for Black Powder.

Abstract: Fire igniting apparatus comprising a shaving stock member formed of a shavable magnesium base alloy and a pyrophoric element secured to the shaving stock member and defining an exposed or exposable surface thereof.The method of igniting a fire which burns with a dazzling white flame by forming finely divided particulates of a magnesium base alloy, consolidating the particulates in close proximity to combustible kindling and striking a pyrophoric element so as to produce a spark which contacts and ignites the particulates causing the same to burn with a dazzling white flame and ignite the combustible kindling.

Abstract: Increased optical transmission is provided for a body of light transmissive polycrystalline alumina body treated at elevated temperatures with a molten flux composition. A tube of the flux polished material which can be used as the light transmissive envelope for high intensity discharge lamps especially sodium vapor lamps, improves light output from the lamp as the result of increased in-line transmission for the treated envelope member. A method of chemically polishing polycrystalline alumina material in this manner is also disclosed.
