20080245252 | NON-TOXIC PERCUSSION PRIMERS AND METHODS OF PREPARING THE SAME - A percussion primer composition including at least one explosive, at least fuel particle having a particle size of about 1500 nm or less, at least one oxidizer, optionally at least one sensitizer, optionally at least one buffer, and to methods of preparing the same. | 10-09-2008 |
20090145320 | Projectile - A projectile ( | 06-11-2009 |
20100005993 | FUZE FOR A PROJECTILE - A fuze for a projectile has a firing assembly for firing a main charge of the projectile and a delay detonator for firing the firing assembly after a delay time which is defined by a burning distance of a delay charge. The delay detonator has a housing with a fuze half in which it is fired and a detonator half which contains a detonator charge for firing the firing assembly. In order to prevent the projectile from misfiring as a result of premature detonation of the delay detonator, the housing has a relief opening in the fuze half, with an opening cross section that can be passed through freely in the firing state of the delay detonator. | 01-14-2010 |
20100251917 | DETONATOR SYSTEM HAVING LINEAR ACTUATOR - Disclosed is a detonation initiator that can form part of a demolition assembly. The detonation initiator can include a linear actuator assembly having a core with a permanent magnet disposed with respect to a coil, and a firing pin coupled to the core and disposed along a longitudinal axis of the linear actuator assembly. A capacitor can be used to store electrical energy derived from an electrical pulse received by the detonation initiator. An electrical circuit can be used to monitor the charge on the capacitor and to discharge the capacitor through the coil of the linear actuator assembly to propel the core along the longitudinal axis of the linear actuator assembly when the charge on the capacitor reaches a charge threshold. | 10-07-2010 |

20110239887 | NON-TOXIC, HEAVY-METAL FREE SENSITIZED EXPLOSIVE PERCUSSION PRIMERS AND METHODS OF PREPARING THE SAME - A non-toxic, non-hydroscopic percussion primer composition and methods of preparing the same, including at least one explosive component that has been traditionally considered a moderately insensitive explosive or secondary explosive, and at least fuel particle component having a particle size of about 1.5 microns to about 12 microns, which allows the use of moderately active metal oxidizers. The sensitivity of the primer composition is created by the interaction between the moderately insensitive explosive and the fuel agent such that traditional primary explosives such as lead styphnate or DDNP are not needed. The primer composition also eliminates the risks and dangers associated with traditional nano-sized fuel particles. | 10-06-2011 |
