Abstract: A blast containment system for trash cans includes a donut-shaped bag having a sealed donut-shaped bottom positioned at the base of the trash can, and an open donut-shaped top positioned and retained at a top periphery of the trash can. An open-ended tubular region extends through the bag between its donut-shaped top and donut-shaped bottom. A rigid container having an open top is disposed in the tubular region of the bag with its open top being coupled to the donut-shaped top of the bag. A liquid fills the bag. A ballistic fabric is situated inside of the trash can and outside of the donut-shaped bag.

Abstract: A blast containment system for trash cans includes a liquid-impervious flexible bag having a sealed bottom positioned at a base of a trash can, and an unsealed top positioned and retained at a top periphery of the trash can. A ring-shaped boot is positioned at the sealed bottom of the flexible bag. A rigid container has a closed bottom press-fit into a central opening of the boot. The rigid container extends from its closed bottom to an open top adapted to be approximately aligned with the top periphery of the trash can. An annular volume is defined between the rigid container the flexible bag. The rigid container has side walls that include ballistic materials. A liquid fills the annular volume.

Abstract: A warhead device of an ordnance including a body of a high strength material, where the body includes a plurality of depressions; an explosive material, where the explosive material fills the body; and a plurality of reactive materials, where each reactive material fills a corresponding depression of the plurality of depressions on the body. The high strength material is configured to endure an internal stress, a first stress caused by the plurality of reactive materials, and a second stress caused by another component of the ordnance. The internal stress, the first stress, and the second stress are in response to acceleration of the ordnance.

Abstract: An adhesive may bond a plastic bonded explosive to a metal surface. The adhesive may include a mixture of hydroxyl-terminated polybutadiene (HTPB) and isophorone di-isocyanate (IPDI) in a weight ratio in the range of about 5 to 1 to about 10 to 1. The adhesive may include a solvent and/or a catalyst.

Abstract: A planar omni-directional inlet assembly is provided for installing on a device, such as a dry filter unit, that draws a fluid medium, such as ambient air, to collect particulate matter suspended in the fluid medium onto a filter. The inlet assembly includes an annular platform removably positionable on the device; an annular nozzle to direct the air from the platform; an annular impactor disposed downstream of the nozzle; a housing that disposes the filter downstream of the impactor; and an exit for passing the air from the filter to the device. The impactor presents a flow obstacle for a portion of the particulate matter. The housing directs the air through the filter. The housing includes a base with a first cavity and a lid with a second cavity such that the filter is disposable between the first and second cavities.

Abstract: This invention relates to a device for accurately delivering a ballistically stable, monolothic projectile at repeatable velocities to a specified target using an explosive event without causing deformation or fragmentation of the projectile. In its most preferred embodiment, the invention will deliver a projectile using an explosive event without substantial deformation or altering of the geometric shape of the projectile. This invention was specifically developed as a preferred device to render safe the firing train of the fuze mechanism of unexploded ordnance (UXO) to dispose of the UXO more safely.
