Abstract: A low temperature flameless aerosol producing fire extinguishing composition containing potassium nitrate and binding fuel is characterized by using cellulose-fibrous mass as a binding fuel, with potassium nitrate at 30-70% and fibrous cellulose mass making up the remainder. A production method for the composition is further provided.

Abstract: A propellant for guns includes at least one energy carrier, nitrocellulose and cellulose acetate butyrate. At least part of the nitrocellulose is alcohol-soluble nitrocellulose. The nitrocellulose serves as a binder and for that purpose is present in a concentration of at least 15% by weight in the propellant. A process for producing a propellant is also provided.

Abstract: A non-toxic, non-hydroscopic percussion primer composition and methods of preparing the same, including at least one explosive component that has been traditionally considered a moderately insensitive explosive or secondary explosive, and at least fuel particle component having a particle size of about 1.5 microns to about 12 microns, which allows the use of moderately active metal oxidizers. The sensitivity of the primer composition is created by the interaction between the moderately insensitive explosive and the fuel agent such that traditional primary explosives such as lead styphnate or DDNP are not needed. The primer composition also eliminates the risks and dangers associated with traditional nano-sized fuel particles.

Abstract: Propellant compositions are provided herein for use in small arms cartridges. Such propellant compositions include from about 70 to about 90% by weight of a cellulose-based organic fuel, from about 5 to about 30% by weight of a non-azide, nitrogen-containing primary organic oxidizer and from about 0.5 to about 10.0% by weight of a secondary nitrate, perchlorate, chlorate of peroxide oxidizer. Preferably, such compositions are in the form of extruded shaped hollow cylindrical grains having a length in the range of 0.030 to 0.200 inch, a diameter in the range 0.040 to 0.070 inch, and having a coaxial opening there through having a wall grain thickness in the range 0.008 to 0.016 inch. Ignition grains are also provided for use alone or in a mixture with the propellant compositions. When used in a small caliber firearm or muzzleloader, the temperature of combustion is at a level that ensures substantially complete combustion of the fuel during firing so that the products of combustion are mostly gaseous.

Abstract: Embodiments of the present subject matter provide an improved percussion primer composition and improved hot-wire igniter acceptor, wherein lead styphnate is replaced with a lead-free material, 4,6-dinitro-7-hydroxybenzofuroxan, potassium salt (KDNP). Embodiments of the percussion primer composition include KDNP, a sensitizer, an oxidizer, calcium silicide, a fuel, and a binder. Sensitizers may include tetracene. Oxidizers may include alkali or alkaline earth nitrates, oxides, or peroxides (such as barium nitrate). Fuel materials may include metals, metal sulfides, or other non-metallic materials. Common binders may include nitrocellulose based shellacs, gum arabic/poly vinyl alcohol mixtures, and guar gum/poly vinyl alcohol mixtures. Embodiments of the hot-wire igniter device include a bridgewire, an acceptor, and an output, where KDNP is the acceptor. Power supply may be in the form of constant current/voltage or current flow from a capacitor discharge.

Abstract: This disclosure considers the use of specifically-sized Nitrocellulose particles of 75 ml fineness, free of other chemicals, as a flame enhancer in a Diazodinitrophenol primer mixture that is free of heavy metal constituents.
