  • Patent number: 10183898
    Abstract: The use of exploding targets has become a popular practice aid in the military, law enforcement and consumer levels. The inventor has conceived and reduced to practice, in a preferred embodiment of the invention, a safe explosive target formulation that is initiated by low-velocity impact. This formulation represents a binary explosive in that the fuel and oxidizer are packaged separately until directly prior to use. Safe, explosive targets for high velocity applications are common. A formulation for low velocity projectile applications which employs an aluminum/magnesium alloy fuel and a potassium perchlorate/ammonium nitrate oxidizer is described.

  • Patent number: 9982983
    Abstract: A hydrogen-propelled projectile for using with a firearm eliminates cleaning the firearm and a method of making the projectile eliminates storing explosive propellant. The projectile has a cylindrical brass body closed at top and sealed at bottom with a primer and a brass seal. When the projectile is used with the firearm, the primer ignites hydrogen in the presence of oxygen, producing water vapor and energy that propels projectile toward a target. To make the projectile a salt water solution is electrolyzed to produce hydrogen and oxygen. A mixture of hydrogen and oxygen is then fed to a loader. The loader fills up the projectile, attached at a gas outlet, with gas by exerting pressure on gas using a load piston and channeling gas to the projectile. Finally, the loader seals the projectile with the primer by pressing a primer ram and affixing the primer at bottom of the projectile.

  • Patent number: 8257523
    Abstract: An apparatus and process for making thermite compositions. The process includes providing a fuel-based slurry and at least one oxidizer-based slurry, formulating combination of fuel-based slurry and oxidizer-based slurry in a solvent to a desired energetic dose depending on nanocomposites' use, circulating the fuel-based slurry/oxidizer-based slurry combination in a mixing device operating semi-continuously during mixing and dispensing cycles forming a homogeneous mixed slurry, agitating ultrasonically or by high shear rate mixers the mixed slurry, and drying of the mixed slurry forming compact structures.

  • Patent number: 8257521
    Abstract: The present invention relates to the field of propellant devices and more particularly to the propellant devices used in weapon systems and munitions. The invention has the two advantages of minimizing the risk associated with accidental attack to which propellant devices may be exposed thanks to the filling of the central channel commonly provided along the core of the cylindrical explosive charge and of greatly increasing the effectiveness of these propellant charges by the use of explosive materials having a very high burn rate.

  • Patent number: 8241443
    Abstract: An electrically initiated security device includes a first energetic sheet, a second energetic sheet, and a corrugated energetic sheet disposed between the first energetic sheet and the second energetic sheet. A first surface of the corrugated energetic sheet defines at least one channel and a second surface of the corrugated energetic sheet defines at least one channel. The electrically initiated security device further includes a first constituent portion disposed in the at least one channel defined by the first surface and a second constituent portion disposed in the at least one channel defined by the second surface. The first constituent portion and the second constituent portion, when mixed, comprise an energetic material.

  • Patent number: 8206522
    Abstract: 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.
