Abstract: A projectile of non-lethal composition includes an outer casing that is substantially sealed prior to impact with a target both when the projectile is in a static condition and when the projectile is in a dynamic condition. A marking material is encapsulated within the outer casing prior to impact. The outer casing is configured to deform and unseal upon impact such that the marking material disperses forward via hydraulic action.

Abstract: A remote pyrotechnic ignition system includes a power supply for producing an electrical current in a transmitting induction coil to induce an electrical current in a receiving induction coil for igniting a pyrotechnic device. Thus, a wireless ignition communication section allows pyrotechnic mortars to be reused and substantially reduces set-up time by eliminating the wiring of fireworks normally required for a pyrotechnic production. Optionally, a capacitor is charged by the power source via a charging circuit and discharged via a firing circuit to produce the electric current in the transmitting coil in a pulse. The capacitor provides a two-stage firing safety feature. An electronic control device such as a circuit board may be mounted on the pyrotechnic device for controlling ignition of the pyrotechnic device and is especially useful in controlling ignition sequencing and overall ignition timing of a lift charge and burst charge of the pyrotechnic device.

In one embodiment, one liner provides various “legs” of liner material and the other liner provides various open receptacle areas, into which such legs may come to rest when the liners are slid together and/or rotated relative to one another. Various recessed and/or raised areas of liner material can thus be randomly created by such adjustments, which lead to select fragmentation of the warhead upon detonation.

Abstract: A less than lethal projectile and method of producing the same comprising of a sealed filled polymeric pouch containing a shot within. The sealed filled polymeric pouch is formed in a form, fill, and seal machine. An automatic loading ammunition machine is fed empty shell casings; the ammunition machine automatically loads the empty shell casing with pre-determined quantities of wad, primer, and gun powder, and subsequently moves the sealed filled polymeric pouch into a projectile compartment of the empty shell casing producing a fully-loaded shell casing to be loaded into a barrel of an ammunition. The polymeric pouch is capable of being inserted into various shell casings depending on the intended use thus allowing for officers and soldiers to select from an array of munitions when confronted with a situation where less than lethal means are required.

The safety device (1) is characterized by a prestressed tube sensor/slide (6) that is connected between the sabot (4), the ignition transmission charge (5) and the explosive material container (2) such that it can release or re-close an ignition channel (13) disposed between the ignition transmission charge (5) and the explosive material.

Abstract: A pyrotechnic training system includes a firing block assembly housed in a first container, a pressure-armed trigger module having two triggers housed in a second container, and a power pack/switch system that connects the firing block assembly and triggers. The first and second containers are remote from each other, and may be made from common objects that might be found in combat zones. Quick-release pins inserted through components of the firing block prevents their separation by exploding ordinance within the firing block, maintaining close electrical contacts within the firing block. The pressure-armed triggers employ a mechanical system that energizes an electrical circuit when pressure is released. Such triggers are arranged such that opening or moving the container triggers an explosion at the remote firing block assembly.

The primer (24) is located inboard of the second end (16) and the base seal (26) to reduce the likelihood of accidental activation. Seals (30) are formed about the body (12) for maintaining gas pressure of deflagrating propellant. The seals (30) may be formed integrally with the body (12) or separately from the body (12) and seated in respective grooves (40) formed circumferentially about the body (12).
