Patent number: 9255774Abstract: A series of small explosive charges are used to preferentially crack the casing of a warhead to provide for a controlled fragmentation of the warhead. During detonation of the warhead's explosive fill, the casing will break early in the process along pre-determined lines resulting in very large fragments that are projected towards the ground and away from innocent civilians. A fragmentation control collar which contacts these charges can be fitted on the outside of existing warheads. An annular liner within the warhead aids in the controlled fragmentation.Type: GrantFiled: June 25, 2009Date of Patent: February 9, 2016Assignee: BATTELLE MEMORIAL INSTITUTEInventors: Thomas E.

Patent number: 8904938Abstract: A blasting cartridge includes a generally cylindrical blasting container, a blasting substance filled in the blasting container, a pair of leadwires contained in the blasting container, and a single thin metal wire connected to tip portions of the pair of leadwires. The leadwires and the thin metal wire are positioned within the blasting substance within the blasting container. The blasting substance is nitromethane, and the thin metal wire is formed of tungsten. With an electric discharge impact blasting apparatus, since the thin metal wire has a higher heating value than a copper wire because of its higher resistance and vaporizes at higher temperatures, it is possible to obtain a greater blasting force at lower voltages than with a blasting apparatus using a copper wire.Type: GrantFiled: September 1, 2010Date of Patent: December 9, 2014Assignee: Hitachi Zosen CorporationInventors: Katsuya Sasaki, Hideaki Kitajima, Ryo Sakamoto, Takaaki Ohnishi

Patent number: 8887640Abstract: A safety fuze includes a magneto striker generator (MSG) as its a power generation source. The MSG provides energy to energize an electronic unit and a safety and arming device. The safety fuze allows safety and arming of military hand grenades, with a fully out-of-line explosive initiator and an integrated power generation means, for improving safety and performance. The MSG includes a striker and a receiving bobbin that houses a conductive coil. The striker comprises a permanent magnet that is mounted on a pivot mechanism for allowing a rotational displacement of the permanent magnet, into the bobbin, in order to generate an electrical current. As the permanent magnet is being inserted inside the bobbin, the magnetic flux change induces an electric current in the coil, creating the necessary energy for the fuze operation.Type: GrantFiled: September 10, 2012Date of Patent: November 18, 2014Assignee: The United States of America as Represented by the Secretary of the ArmyInventors: Ryan R.

Patent number: 8869701Abstract: The present invention describes an improved cartridged projectile (100). The cartridged projectile (100) comprises a projectile (110) seating at a mouth of a cartridge case (130). The cartridge case (130) has a base (134) that houses a high pressure chamber (150). A side of the high pressure chamber (150) is capped by a pressure disc (170), which is secured onto the base of the cartridge case by a nozzle ring (160). The nozzle ring (160) has a tapered or conical surface that allows the pressure disc (170) to flex, and a surface (171) of the pressure disc (170) exterior of the high pressure chamber has intersecting V-shaped grooves (172). When propellant in the high pressure chamber (150) is burned efficiently, high pressure gases developing inside the high pressure chamber cause the pressure disc (170) to rupture at a predetermined pressure along the grooves (172) so that the gases propel the projectile (110) out of a barrel at a higher speed of about 100 m/s or more.Type: GrantFiled: September 26, 2011Date of Patent: October 28, 2014Assignee: Advanced Material Engineering Pte LtdInventors: Cheng Hok Aw, Chee Keong Yak, Soo Chew Sie, Renjie Xie
