Patent number: 7344610Abstract: Sulfur free propellant compositions for use as a blackpowder substitute in firearms, munitions, and pyrotechnics to form combustion byproducts that are water soluble and are free of corrosive sulfur compounds. Formulations include an ignition aid of a gluconic acid salt or an alkali metal nitrobenzoate salt or a mixture of the two salts in combination with various known oxidizing and reducing agents and with various known propellant additives. The oxidizing and reducing agents may be selected from the group consisting of carbon, lactose, potassium nitrate, potassium perchlorate, sodium benzoate, and mixtures thereof. The propellant additives may be selected from the group consisting of binders, burning rate modifiers, flow agents, colorants, coating agents, moisture retardants and mixtures thereof.Type: GrantFiled: January 28, 2003Date of Patent: March 18, 2008Assignee: Hodgdon Powder Company, Inc.Inventors: G. Dean Barrett, John A. Conkling

Patent number: 5945627Abstract: In-hole and surface detonators are provided which are essentially free from primary explosives. The detonators utilize a high energy pyrotechnic mixture of a fuel and an oxidizer for initiation of a base charge enclosed in the detonator, or for the initiation of an adjacent shock tube. Improved safety during manufacture of detonators is achieved.Type: GrantFiled: September 19, 1996Date of Patent: August 31, 1999Assignee: ICI CanadaInventors: Jean-Luc Arpin, Rejean Aube, John A. Conkling

Patent number: 5811726Abstract: The present invention provides a multi-component explosive composition coising 2-ethylhexyl nitrate and a granular solid oxidizer. An optional additional component is a second fuel, e.g., aluminum. An optional component in the absence of the second fuel is azodicarbonamide. Methods for making the explosive are provided.Type: GrantFiled: February 28, 1996Date of Patent: September 22, 1998Assignee: The United States of America as represented by the Secretary of the NavyInventors: Jerry S. Brown, John A. Conkling

Patent number: 5627339Abstract: Energetic compositions and the process for obtaining same for use as the itable composition in infrared-emitting decoy flares, for high-temperature ignition compositions, and the like, are disclosed. These compositions are attained by combining a fluorinated hydrocarbon, either in a liquid state or as a water emulsion, with a powdered metal fuel such as aluminum, magnesium, titanium or zirconium to yield volatile solvent free energetic compositions.Type: GrantFiled: March 28, 1996Date of Patent: May 6, 1997Assignee: The United States of America as represented by the Secretary of the NavyInventors: Jerry S. Brown, John A. Conkling

Patent number: 5392713Abstract: The invention relates to a shock insensitive explosive train initiating dce including a thin elongated metal casing containing a quantity of hydrated metal picrate therein, a thermite igniter composition disposed adjacent to the hydrated metal picrate charge and an ignition means selected from ignition means consisting of an electric match and a length of fuze cord. In a specific example, the hydrated metal picrate charge is barium picrate hydrate which may be disposed in an open (FIG. 1) or a sealed (FIG. 2) copper or aluminum casing. In the embodiment of FIG. 3, a tin/zinc alloy, protective, safety cover is disposed over a portion of the hydrated metal picrate. This safety cover has a low melting point (200.degree. C.) and is adapted to melt in the event of a fire to thereby "unconfine" the hydrate metal picrate charge prior to it reaching explosion temperature of approximately 341.degree. C.Type: GrantFiled: February 14, 1994Date of Patent: February 28, 1995Assignee: The United States of America as represented by the Secretary of the NavyInventors: Jerry S. Brown, John A. Conkling
