Patent number: 6308633Abstract: A method and a device for destroying drifting sea mines (5). According to the invention, a capture-and-destroy device (11) is brought into the vicinity of the drifting sea mine (5) with the aid of a buoyant body (12, 22) having a coupled-on drive system (13) or a drive device (24), and the mine is captured in that the sea mine (5) is surrounded by deployment of a capture net (16) normally located in a capture unit (11.1) of the capture-and-destroy device (11). A motorized element (17) disposed in the capture unit (11.1) draws the capture net (16) together automatically until the captured sea mine (5) rests directly against a destroyer unit (11.2) with a destructive charge (15). The destructive charge (15) is then automatically detonated to destroy the mine.Type: GrantFiled: January 14, 2000Date of Patent: October 30, 2001Assignee: Rheinmetall Landsysteme GmbHInventors: Hermann Grosch, Werner Hasse, Uwe Eisenkolb

Patent number: 6298764Abstract: A muzzle flash and blast suppressor comprising a body of reticulated refractory foam generally surrounding the projectile path adjacent the muzzle of a device. One side of the body of foam is exposed to the pressure within the projectile path just behind the projectile, and the other side is exposed to the unconfined ambient pressure. The foam is required to be possessed of sufficient structural strength to permit its exterior side to be exposed without confinement to the ambient environment. Hot exhaust gasses flowing laterally of the projectile path pass through the body from the high to the low pressure side. In such passage the gasses are cooled by expansion and by contact with the interstices of the body. Debris is filtered out and the pressure is substantially reduced. Typically, the refractory foam has from approximately 30 to 100 pores per inch and is from approximately 90 to 50 percent void volume.Type: GrantFiled: January 14, 2000Date of Patent: October 9, 2001Assignee: UltrametInventors: Andrew J. Sherman, Jerry Brockmeyer, Gregory Peters, Robert H. Tuffias

Patent number: 6298595Abstract: A washer shaped chum that can be secured to a fishing line that is particularly designed to release scent in a controlled release manner, the controlled release mechanism allows an extension of the time the fish would be attracted to the region surrounding the bait and the hook, said chum being composed essentially of fishmeal, fish oil, an inorganic salt, an organic hydrophobic substrate and a glident.Type: GrantFiled: June 2, 1999Date of Patent: October 9, 2001Inventor: Bert J. Friedlob

Patent number: 6286408Abstract: An energy-absorbing countermass assembly for a weapon has a crushable section, a piston at the forward end of the crushable section, and at the rearward end of the crushable section. The countermass can be a rupturable enclosure filled with a dispersible material.Type: GrantFiled: January 4, 2000Date of Patent: September 11, 2001Assignee: The United States of America as represented by the Secretary of the NavyInventors: Matthew Sanford, Thomas A. DelGuidice

Patent number: 6282833Abstract: A device for repelling insects from the vicinity of a support surface for the repelling device. The repelling device has a base which can be placed against an upwardly facing support surface to thereby maintain the repelling device in an operative position, a first arm connected to the base and in an elevated position above the upwardly facing surface on which the repelling device is maintained in the operative position and rotatable around a vertically extending axis, a first element depending from the first arm and rotatable with the first arm around the vertically extending axis, and a drive which is operable to rotate the first arm around the vertically extending axis to thereby cause the first element to trace an annular path around the vertically extending axis.Type: GrantFiled: December 9, 1999Date of Patent: September 4, 2001Inventor: Daynin Dashefsky

Patent number: 6272996Abstract: An in-line initiator and firing device assembly includes a shock tube assembly. An in-line initiator is provided for initiating a shock wave along the shock tube assembly, and includes an end sleeve having a bore extending between input and output ends. At least a portion of a surface defining the bore toward the output end of the end sleeve is threaded for threadably receiving and forming threads on an outer surface of the input end of the shock tube assembly. A first retaining device is associated with the end sleeve for receiving a shock wave triggering device and securing the triggering device to the input end of the end sleeve. A firing device assembly is activated by a shock wave transmitted through the shock tube assembly. The firing device includes a barrel having a bore extending between input and output ends. The input end of the barrel communicates with the output end of the shock tube assembly and the output end communicates with a firing device.Type: GrantFiled: September 28, 1999Date of Patent: August 14, 2001Assignee: Shock Tube Systems, Inc.Inventors: John P. O'Brien, Stephen W. Bartholomew
