Patent number: 7789983Abstract: A method is provided for making blast explosive molding powder. According to an aspect of the invention, energetic solids and a metal powder are suspended in a bulk phase fluid. Lacquer is added to an energetic solids and metal powder suspension to achieve a super-saturated solution. Final granulation of the super-saturated solution is optimized to form a fluidized metallized energetic molding powder. The fluidized metallized energetic molding powder is distilled to remove an organic solvent component of the lacquer, which is reclaimed through distillation. The bulk phase fluid is decanted to recover a wet metallized energetic molding powder. The bulk phase fluid is reclaimed through distillation. The wet metallized energetic molding powder is dried to form a dry metallized energetic molding powder. This method is especially useful in making insensitive enhanced blast explosive molding powders with high metal powder content.Type: GrantFiled: April 13, 2005Date of Patent: September 7, 2010Assignee: The United States of America as represented by the Secretary of the NavyInventors: Kirk E.

Patent number: 7398734Abstract: A MEMS resettable timer including a primary inertial element and at least one secondary inertial element, which includes a camming surface. When the secondary inertial element moves, its camming surface engages the camming surface of a locking element to remove it from the notch of a subsequent inertial element.

Patent number: 7145003Abstract: A process for synthesizing 1,5-Dinosyl-3,3,7,7-tetrakis(difluoramino) octahydro-1,5-diazocine (DNTDFD) by reacting tetrahydro-1,5-bis(4-nitrobenzenesulfonyl)-1,5-diazocine-3,7-(2H, 6H) dione with HNF2/oleum initially approximately between ?5 and 0 degrees C., and allowing the temperature to rise to between 10 degrees C. and ambient temperature during said reaction to initiate difluoramination producing product DNTDFD. A 2:1 mixture of FREONĀ® 11 refrigerant and pentane or cyclopentane, or pentane alone is used as a diluent and absorbent for the reagent difluoramine. The present invention reduces the time required to produce DNTDFD from about two weeks to one to three days and reduces the need to use relatively large quantities of FREONĀ® 11, a compound which is damaging to the environment.Type: GrantFiled: November 24, 2003Date of Patent: December 5, 2006Assignee: The United States of America as represented by the Secrectary of the NavyInventors: Horst G.

Patent number: 7063810Abstract: The invention comprises a continuous, integrated process to produce a multiple layered energetic material where the layers comprise energetic materials having, at least, two different burning rates. The process uses at least two twin-screw extruders to process at least two different energetic materials. These energetic materials are extruded into a co-extrusion die that, first, thins each energetic material flow into layers, and, then, combines the layers into a multiple layered energetic material. One embodiment of the invention also includes a remote take away system that completes processing the multiple layered energetic material after it leaves the co-extrusion die. The outer edges of the multiple layered material are first trim cut, then rolled into wrapped spools. Finally, the wrapped spools are cut into specified lengths for final use. These cutting, trimming and rolling steps are all done automatically, with no personnel handling required.Type: GrantFiled: November 27, 2002Date of Patent: June 20, 2006Assignee: The United States of America as represented by the Secretary of the NavyInventors: Constance Murphy, John Brough, Richard S.

Patent number: 6966263Abstract: The invention comprises a device that uses a flexible material, preferably in a mostly square shape. An explosive charge, usually in the form of a sheet of explosives, is cut to fit on the top side of the flexible material. A cutting plate, having orthogonal grooves on the top, is placed under the flexible material. An initiating means is connected to the explosive charge so that upon initiation, the grooves focus the explosive charge so that the cutting plate forms a plurality of petals that press into a soft metal container to create a fragment-free opening in the soft metal target material.Type: GrantFiled: March 18, 2004Date of Patent: November 22, 2005Assignee: The United States of America as represented by the Secretary of the NavyInventors: Michael L. Greene, Samuel J. De Vane

Patent number: 6964699Abstract: A wet scrubber having a series of chambers for capturing and cooling exhaust gases generated during static test firing of rocket motors. Exhaust gas enters an inlet to a first chamber and is cooled and slowed by a spray solution. HCL gas is condensed and absorbed by the spray solution and precipitates to a liquid slurry at the bottom of the device. The remaining exhaust products enter a demister chamber where nozzles continue to spray the gasses as they pass upward and through a mesh-style demister at the top of the vessel. The demister filters liquid and solid waste particles from the gas stream, and the clean, dry gases are accelerated through a centrifugal fan into the atmosphere. A deflector is positioned within the inlet to the first chamber for containing parts in the event of a motor mal-function.Type: GrantFiled: June 5, 2002Date of Patent: November 15, 2005Assignee: The United States of America as represented by the Secretary of the NavyInventors: Richard H. Carns, Gerald Armstrong, Robert H. Rast, Dennis R. Mitchell

Patent number: 6962113Abstract: The present invention comprises a warhead designed to provide a number of spiraling tendrils composed of segmented rods that move in an increasing radial arc in order to defeat a target. The warhead comprises a substantially cylindrical explosive charge having a plurality of rod segments arranged circumferentially around the explosive charge in a plurality of horizontal layers. As the horizontal layers descend down the explosive charge, the rod segments are offset from those directly above and below them to create a pattern that appears to be twisted columns. The number of columns is equivalent to the number of rod segments in each horizontal layer.Type: GrantFiled: May 9, 2003Date of Patent: November 8, 2005Assignee: The United States of America as represented by the Secretary of the NavyInventors: Victor John Carlson, Timothy S.

Patent number: 6895871Abstract: A portable, re-usable, elevated platform that provides a large, non-slip, grated surface on which an individual wearing a fully-encapsulated, hazardous materials suit may stand, and turn as needed to ensure thorough on-site decontamination. The platform generally comprises a top grate and two folding/pivoting support leg assemblies. The elevated design of the platform allows for the collection of the hazardous material runoff in a containment vessel deployed underneath. The platform is fabricated of impervious, strong, lightweight materials to prevent absorption of any hazardous materials and to provide sufficient structural strength while keeping its overall weight reasonable. The design is simple and straightforward, and can be economically manufactured.Type: GrantFiled: January 15, 2003Date of Patent: May 24, 2005Assignee: The United States of America as represented by the Secretary of the NavyInventors: William G.
