Patent number: 11307012Abstract: An explosive threat mitigation unit (TMU) stands ready to receive a suspected bomb, enclose it, and contain the explosion if one occurs. An operator protects bystanders and surroundings by putting the suspected bomb in a TMU and then closing the TMU. If the bomb goes off, the TMU mitigates the effects of both the blast and the fragments. One variation has a container, a tube, a cap, and a door. The container includes an opening. The tube, arranged in the container, aligns with the opening. The cap slides through the opening and over the tube. The door slides into place to close the opening and enclose the cap within the container.Type: GrantFiled: July 20, 2021Date of Patent: April 19, 2022Assignee: The Government of the United States of America, as represented by the Secretary of Homeland SecurityInventors: Chian-Fong Yen, Ashiq A. Quabili, Chih-Tsai Chen, Nelson Carey, Robert P. Kaste, Patrick O'Connor, Jian H. Yu

Publication number: 20110068208Abstract: A process for forming a prestressed structure that includes: winding a plurality of fibers around a structure in order to compressively prestress the structure; wherein the winding is achieved by a fiber tensioning device that includes: a plurality of axles rotatably supported by the frame, each axle having a drum that engages the plurality of aligned fibers, each axle also having a sprocket; a chain for coupling each of the sprockets; a brake connected to the chain which opposes the motion of the chain thus increasing the tension in the plurality of aligned fibers that are in contact with said drums; and whereby the aligned fibers are wound onto the structure under increased tension thus imparting compressive pressure between the aligned fibers on to the wound structure.Type: ApplicationFiled: November 22, 2010Publication date: March 24, 2011Applicant: US GOVERNMENT AS REPRESENTED BY THE SECRETARY OF ARMYInventors: RYAN P. EMERSON, ROBERT P. KASTE

Publication number: 20080272221Abstract: A fiber tensioning device, including a frame, two or more axles rotatably supported by the frame, each axle having a drum that engages the fiber, each axle also having a wheel, a belt for coupling each of the wheels, and a brake for controlling the belt.Type: ApplicationFiled: May 1, 2007Publication date: November 6, 2008Inventors: Ryan P. Emerson, Robert P. Kaste

Patent number: 5644100Abstract: A shotgun shell includes a sabot with a tubular portion extending from a e, a chamber disposed within the tubular portion in communication with an opening in the base, a load of shot disposed within the tubular portion around the chamber, and a valve disposed between the chamber and the opening to control the flow of propellant gases into and out of the chamber. The valve can be a choke with a flow constricting orifice that delays pressurization and depressurization of the chamber. Alternatively, or in addition to a choke valve, a movable valve member can be disposed between the chamber and the opening to seal with a valve seat in order to capture high pressure propellant gases which, upon emergence of the sabot from the gun barrel, will assist in creating a highly dispersed shot pattern at close range. Also disclosed are a number of ways in which the sabot can be modified to control the stiffness of the tubular portion in order to change the shape of the shot pattern to suit specific applications.Type: GrantFiled: August 19, 1996Date of Patent: July 1, 1997Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Lawrence J. Puckett, Robert P. Kaste

Patent number: 5313889Abstract: A double ramped, saboted, kinetic energy assembly automatically aligns a jectile in a gun tube. The assembly has an acceleration activated device consisting of a split centering ring causing alignment during the early phase of the shot motion of the projectile. The assembly also includes a series of small protrusions or a continuous expandable ring which forces and maintains the projectile into a straight aligned position during its traversal of the gun tube. The assembly may have either a smooth bore or a rifled bore gun tube. The disclosure also include a method related to the assembly.Type: GrantFiled: January 4, 1993Date of Patent: May 24, 1994Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Stephen A. Wilkerson, Robert P. Kaste, Bruce P. Burns

Patent number: 5103735Abstract: An improved segmented doubled ramp sabot for launching a sub-caliber projile, comprising a plurality of longitudinal ribs disposed on the forward and aft ramp sections of the sabot, and a plurality of longitudinal ribs disposed between an obturating band seat and a conical borerider. The combined cross sectional area of the double ramp segments, together with the combined cross sectional area of the ribs, are such that the sum of these areas is approximately equal to the cross sectional area of a double ramp sabot representative of prior art. As a result, axial stiffness is unaffected, and uniform shear traction forces between the sabot and projectile are maintained. In addition, the transverse bending stiffness of the sabot is improved, thereby reducing in-bore vibration and shot dispersion while allowing maximum energy transfer to the projectile. Use of a stiffer material for the ribs further improves transverse bending stiffness and performance.Type: GrantFiled: June 20, 1991Date of Patent: April 14, 1992Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Robert P. Kaste, Bruce P. Burns, Stephen A. Wilkerson, Peter Plostins

Patent number: 4845995Abstract: A material tester which allows for material characterization under hydrodmic loading including very high rates of loading such as found in ballistic applications, and which includes various interchangeable fittings to allow the tester to simultaneously subject a test specimen to (1) radial compression and axial tension, or (2) radial compression and axial compression, or (3) radial compression and axial shearing stress.Type: GrantFiled: July 14, 1988Date of Patent: July 11, 1989Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Robert P. Kaste, Robert E. Tompkins

Patent number: 4499811Abstract: The present invention discloses a blank firing attachment for gun tubes of utomatic or semi-automatic weapons when firing blank cartridges. The attachment includes a flash suppressor having milled axial slots threadably attached to the gun tube, a slidable cam pivotally mounted to a collar threadably attached to a shaft containing a restricted passage for gas flow from the gun tube, and a number of locking lugs pivotally connected to the collar. Axial movement of the shaft causes the lugs to engage the axial slots and the shaft to engage the gun tube end, thereby restricting gas flow from the gun and providing back pressure to permit automatic or semi-automatic firing of the weapon when using blank ammunition. Thus, the attachment is made compact and is fireable in all modes for various weapons, including M231 weapon.Type: GrantFiled: October 11, 1983Date of Patent: February 19, 1985Assignee: The United States of America as represented by the Secretary of the ArmyInventor: Robert P.
