20100242773PROJECTILE HAVING IGNIT ABLE PAYLOAD WITH DELAY COLUMN IGNITER - A modified projectile round which is configured to function with a propellant cartridge such as described in U.S. Pat. No. 7,004,074. The projectile assembly uses a High-Low gas pressure cartridge to launch the projectile. When the high pressure cartridge is ignited, hot propellant gases rupture a burst cup and shoot propellant gases toward the aft end of the projectile. The hot propellant gases impinge against a delay carrier located in the aft end of the projectile. The contents of the delay carrier are thereby ignited. The delay carrier includes one or more delay columns ultimately terminating in an igniter charge. The delay columns burn as the projectile is in flight. A specified amount of time later, the igniter charge ignites an ignitable payload—such as a marker flare candle.09-30-2010

20120204750PRESSURE-RELIEF SYSTEM FOR GUN FIRED CANNON CARTRIDGES - A high velocity cartridge munition comprises a cartridge shell and a projectile inserted into it. A propulsion chamber within the cartridge shell receives a propulsive charge that may be ignited by a pyrotechnic igniter and that develops propulsive gases that act on the base of the projectile, driving it out of the cartridge shell. To prevent the pyrotechnic igniter from igniting spontaneously, and from igniting the propulsive charge due to the ambient temperature or because of a fire, which would cause the cartridge shell and projectile to be separated and fly apart, at least one exhaust channel between the propulsion chamber and the exterior of the cartridge shell is filled with a fusible material. The fusible material has a lower melting point than the ignition point of the igniter and of the propulsive charge. If the ambient temperature of the cartridge shell rises above the melting point of the fusible material, it melts, releasing the exhaust channels, so that, upon delayed ignition of the propulsive charge, it burns without pressure buildup, and the cartridge shell and projectile remain together. At least one non-fusible, rupturable member is positioned between the fusible material and the propulsive charge to provide mechanical support under normal conditions but to facilitate release of gases if the propulsive charge ignites.08-16-2012

20160091284Electro Control Hazing Device (ECHD) - An electronic conditioning device delivers electric shocks correlated with sounds or driven by a signal associated with a sound sequence. The sound sequence can be a few seconds of a recorded human voice, a siren, a single tone, and so forth. A sound generator emits the sound sequence audibly. A power supply is electrically connected to the various components and provides energy to a shock inducer or electrodes embedded in the skin of a target. The device administers voltage spikes and sounds in a coordinated fashion. The conditioning encourages the target to associate certain sounds with the electric shock. Power may be supplied by a battery, a piezoelectric flexible film or movable magnet that converts kinetic motion into electric energy. Preferably, the device is applied to a target by loading the device into a shotgun shell and firing the loaded shell at the target from a rifle, pistol or shotgun.03-31-2016
