The spherical shaped structure has a hollow inner core that is symmetrically disposed about an ax... | 03/20/2007 |
| 7168367 | Submunition fuze An improved fuze for a submunition grenade designed to be launched from a cargo projectile comprising a fuze, a charge and a casing; the improved fuze comprising a fuze housing; a threaded firing pin having a pointed tip, oriented coaxially with the sub... | 01/30/2007 |
| 6705231 | Safing and arming device for artillery submunitions A safing and arming device is provided for a warhead or round which is to be launched by a rifled gun and which includes submunitions. A slider is disposed in a housing between a detonator and lead cup and is movable between a first, safe position wherein the slider... | 03/16/2004 |
| 6568329 | Microelectromechanical system (MEMS) safe and arm apparatus A MEMS type safe and arm apparatus for a fuze includes a setback slider responsive to a first setback acceleration, the setback slider moving linearly in response to the first setback acceleration; a setforward slider responsive to a first setforward acce... | 05/27/2003 |
| 6564716 | Fuzes having centrifugal arming lock for a munition A fuze for a munition adapted to prevent unintended arming thereof. The fuze incorporates an arming screw having a keyed portion and a centrifugal locking mechanism for preventing rotation of the arming screw unless the fuze mechanism is in a rapidly spin... | 05/20/2003 |
| 6237495 | Self-destructing impact fuse A self destructing impact fuse including a cylindrical firing pin having a hollow centrifugal chamber for holding a number of spheres and a number of radial openings on its surface for exposing portions of the spheres when the chamber is spun. At one end ... | 05/29/2001 |
| 4694751 | Explosive system for guided missiles and rocket projectiles An explosive system for use in projectiles such as guided missiles and rocket projectiles, includes an explosive charge and an ignition booster for igniting the explosive charge. A detonator is provided for igniting the booster. An ignition transfer devic... | 09/22/1987 |
| 4622898 | Spin activated mechanism The mechanism consists of a one coil spring disposed a spaced distance about the inner circumference of a cylindrical housing; and a lever pivotally attached to said housing. When the device is subjected to centrifugal forces the coil is forced outward to... | 11/18/1986 |
| 4612858 | Fuse for a satellite projectile The invention relates to a fuse for a satellite projectile that is expelled from a carrier projectile.
