Abstract: A system for extracting threats buried underground includes a housing, a shaped charge coupled to the housing at one end, and an explosive projectile disposed in the housing and spaced-apart from the shaped charge. The explosive projectile includes an open-ended pipe, a detonation line wrapped about the pipe and extending away therefrom and through the housing, an explosive material disposed about and in contact with the detonation line wrapped about the pipe. The explosive projectile also includes a first donut-shaped plate at one end of the pipe, a second donut-shaped plate at another end of the pipe, and a third donut-shaped plate coupled to and spaced-apart from the second donut-shaped plate. A flow path extends through the plates and the pipe.

Abstract: An EOD disruptor system for penetrating steel encased explosive devices has a barrel and a blank cartridge loaded in the EOD disruptor. A water column is disposed in the barrel in front of the blank cartridge. A water plug is disposed in front of the water column. A muzzle-loaded projectile is disposed in front of the water plug. The projectile includes a shaft portion at least partially disposed in the barrel and a front portion disposed outside of the barrel. The shaft portion may have a length from about four inches to about eighteen inches. The projectile may have a weight from about four ounces to about two pounds. The ratio of the length of the shaft portion of the projectile to the inner barrel diameter may be in a range of about two to about 50.

Abstract: An apparatus for lifting a buried explosive device includes a T-shaped base including a flange member and a web member. The web member has one end fixed at a right angle to the midpoint of the flange member. A vertical upright member is fixed at one end to the midpoint of the flange member. A diagonal member is fixed at one end to the other end of the vertical upright member and fixed at another end to a second end of the web member that is distal the flange member. The vertical upright member is at least twice a length of the web member. The flange member, the web member, the vertical upright member and the diagonal member are L-channel members made of carbon fiber.

Abstract: A support gasket for use with a concrete panel mold system comprises an inner stiffener bar and engagement structure, attached to or formed integrally with the stiffening bar. The engagement structure is operable to engage an adjacent material. A pliable gasket material is disposed about the inner stiffening bar and is positively engaged with the engagement structure to secure the gasket material to the stiffening bar.

Abstract: A form for creating a pattern in uncured concrete during a vertical column casting process includes an end wall and at least one side wall, extending from an edge of the end wall with the side wall and end wall cooperatively defining a corner therebetween. A pliable liner is attached to the end wall and the side wall and operably joins the side wall to the edge of the end wall to define a mold cavity. At least one patterned surface is formed on or in the pliable liner and is operable to form a corresponding pattern into concrete disposed in an uncured form in the old cavity. A notch is formed in the pliable liner and extends along the corner and forms a pivotable joint between the end wall and the side wall to facilitate removal of the form device from about the concrete after the concrete has at least partially cured.

Abstract: A form for creating a pattern in uncured concrete during a casting process includes a support frame and a perforated reinforcing structure coupled adjacent to at least a portion of the support frame. The perforated reinforcing structure includes a plurality of apertures defined therein. A pliable liner is disposed at least partially within the plurality of apertures and at least partially about the perforated reinforcing structure adjacent the support structure. The pliable liner has a patterned surface formed thereon for creating a corresponding pattern in uncured concrete poured adjacent the form.
