Patent number: 6889594Abstract: A recoil mitigation apparatus for a projectile-firing device, such as an explosives disrupter, is provided. At least one brake shoe is positioned proximate the projectile-firing device and means are provided for urging the at least one brake shoe toward the projectile-firing device. The urging of the at least one brake shoe provides a frictional force to mitigate the recoil of the projectile-firing device. In a preferred embodiment, at least one pair of brake shoes are provided. In a further preferred embodiment, the each of the at least one pair of brake shoes are positioned in a facing, spaced apart relationship and the at least one pair of brake shoe combination is positioned in a coaxial relationship to the projectile-firing device.Type: GrantFiled: February 28, 2003Date of Patent: May 10, 2005Assignee: Battelle Memorial InstituteInventors: Harvey Nelson Ebersole, Jr., Bradley G. DeRoos

Patent number: 6851171Abstract: A multi-channel device fabrication process and multi-channel devices made therefrom wherein two ribbons of sheet material edge webs and, optionally, additional webs and/or support members are secured to a ribbon of sheet material base web. The resulting partial laminate is separated into subassemblies, each subassembly comprising a base and two edge strips and, optionally, additional strips which cooperate to define a plurality of open channels with, optionally, support members. A plurality of subassemblies may stacked together with an end plate to form a complete stack, the edges of each subassembly being attached together to form a complete unit. One or more headers or manifolds may be attached to the outside of the complete unit to provide combined fluid inlet to, and egress from, the unit.Type: GrantFiled: November 27, 2002Date of Patent: February 8, 2005Assignee: Battelle Memorial InstituteInventor: Stephen C. Schmitt

Patent number: 6789456Abstract: A braking system is provided for mitigating the linear or rotational motion of an object having an axis, the linear or rotational motion being coaxial with the axis. In particular, the motion is the type which is the result of an impulse imposed over a short period of time, typically less than one second. The object whose linear or rotational motion is to be mitigated is disposed coaxially within a tube. The braking system includes at least one brake shoe positioned within an annular free space defined by the outer surface of the object and the inner surface of the tube. The at least one break shoe may be urged against the outer surface of the object or the inner surface of the tube to effect the mitigation.Type: GrantFiled: February 28, 2003Date of Patent: September 14, 2004Assignee: Battelle Memorial InstituteInventors: Bradley G. DeRoos, Harvey N. Ebersole, Jr.

Patent number: 6745663Abstract: A recoil-mitigated projectile-firing device comprising a firing assembly, the firing assembly comprising the projectile-firing device secured within a tube and the recoil-mitigated projectile-firing device further comprising a brake assembly surrounding a portion of the tube. The brake assembly comprising at least one brake shoe supported within a frame and means for urging the at least one brake shoe against the outer surface of the tube. When the projectile-firing device is discharged, the firing assembly moves relative to the brake assembly and the frictional force mitigates the recoil.Type: GrantFiled: February 28, 2003Date of Patent: June 8, 2004Assignee: Battelle Memorial InstituteInventors: Harvey N. Ebersole, Paul T. Ratajczak, James F. Mank

Patent number: 6344146Abstract: A portable, self-contained, fully integrated water purification device which includes a receptacle modified to accommodate a filtration assembly for purifying water, and to store water following purification. The receptacle provides separate openings for water intake, and water outflow. The filtration assembly includes a pump and a multistage filter cartridge. Pump action draws water into the water purification device and forces the water through the multistage filter and into the receptacle. Purified water may be stored in the receptacle until consumption.Type: GrantFiled: December 9, 1999Date of Patent: February 5, 2002Assignee: Battelle Memorial InstituteInventors: John S.
