  • Patent number: 11015906
    Abstract: An aerial projectile apparatus provides a means for marking terrestrial and marine locations for identification from afar, as by aerial reconnaissance. The projectile is launched from ground level at a location where identification is desired. When the projectile is lofted to an appropriate elevation, it disperses a spray of marker substance in the form of droplets or solid particles. When the sprayed marker substance settles to ground level, it leaves a mark on the landscape or marine surface indicating the location for identification by aerial reconnaissance.

  • Patent number: 7261037
    Abstract: The pyrotechnic animal dispersal device includes an aerodynamic stabilizer for attachment to a pyrotechnic rocket cartridge and a connector sleeve for joining an explosive cartridge to the rocket cartridge. The connector sleeve has an annular disc disposed therein so that slow burning fuel from the rocket cartridge can pass through the disc and detonate the explosive cartridge when the rocket cartridge nears the end of its flight, thereby extending the range of the explosive cartridge. The cartridges are of the pyrotechnic variety launched from a handheld launcher.

  • Patent number: 6912958
    Abstract: A fireworks artillery shell for use as a consumer firework which may be propelled by the use of a mortar is provided which includes a casing, a lift charge, an effects charge, a timing fuse and an ignition fuse, and seals. The seals are provided within the casing above and below the effects charge to increase the burst effect of the effects charge. The lift charge is positioned within the casing and below the lower seal, and upon ignition, lifts the fireworks artillery shell into the air. The seals promote a harder break and more explosive effect from the effects charge without interfering with the lifting charge.

  • Patent number: 6889612
    Abstract: A long-distance blast banger including a cartridge loaded with a blast banger made up from plastic material. The blast banger encompasses a sound explosives cup and a delay cup. The sound explosives cup is loaded with a sound explosives agent having components including perchloryl potassium, magnesium powder and aluminum powder. A sufficient sound value is acquired through appropriate compacting of the sound explosives cup, and therefrom realizes uniform shattering of the cup into small fragments that are insufficient to cause injury. Furthermore, at least two helical grooves extending from a bottom to a top of the cartridge are defined on an inner wall thereof, and ear attachments are configured on a base of an outer wall of the blast banger so as to correspond with the helical grooves, thereby engendering a spinning stability effect during flight time of the blast banger, reducing wind resistance, and thus increasing flight range.

  • Patent number: 6324955
    Abstract: An explosive countermeasure device is designed to negate an electro-optical seeker system of a missile at least temporarily so that it loses lock on a target aircraft. The device has a central explosive charge with a detonator and a container surrounding the charge for holding a noble gas under pressure. When the charge is detonated, the resultant explosive shock wave will heat the gas to a temperature sufficient for it to emit a short, intense flash of light before the container disintegrates, blinding the electro-optical seeker system at least temporarily.

  • Patent number: 4457233
    Abstract: A new aerial bomb for uses such as scaring birds and other such creatures away from airport runways, farmer's fields, and the like, is disclsoed. When detonated in a shotgun, the aerial bomb provides two reports; the first occurring when the propelling powder in the shotgun shell is ignited, and the second occuring when the ignited projectile bomb explodes several seconds later. A unique fuse is provided such that no physical connection is necessary in the shotgun shell between the propellant powder and the explosive projectile fuse. Furthermore, the casing of the shell is provided with visual observation means and the projectile is provided with position indicator means, so that the fully assembled aerial bomb may be readily inspected to verify proper installation of the projectile in the casing.
