Status In Force
Filing Date 2017-05-09
Publication Date 2017-11-16
Owner AMTEC LESS LETHAL SYSTEMS, INC. (USA)

Abstract

A firearm cartridge with a specially-configured token disc added to its base. The token includes an outer section and a central strike plate. The strike plate includes a strike ball at its center. The presence of the token increases the effective length of the cartridge and thereby prevents the closure of the bolt of a conventional firearm. As a result, the inventive cartridge cannot be fired in a conventional firearm.

Abstract

In a multi-burst diversionary device (10) containing a number of pyrotechnic cartridges (22) arranged in a series and a firing arrangement (14), a first of the cartridges is ignited by the firing arrangement, the remaining cartridges are each ignited sequentially by the flash of pressure and heat (hot gasses) produced when a previous cartridge in the series deflagrates. The device has a housing (12) defining a number of compartments (20) in which the cartridges are received. The housing defines flow paths interconnecting the compartments in series and the first compartment with the firing arrangement. Each compartment is also fluidly connected with atmosphere.

Abstract

A grenade firing mechanism (12) includes a body (24) containing a firing pin (20) and a firing pin actuator mechanism (22). A safety system includes twist to arm collar (70) and a safety interlock (92). The collar is movable between an unarmed position and an armed position and the safety interlock is movable between a collar locking position, a collar release position and a firing position. When the collar (70) is in the unarmed position and the safety interlock (92) is in the collar locking position, actuation of the firing pin (20) is inhibited and the safety interlock (92) inhibits movement of the collar to the armed position. When the safety interlock (92) is in the collar release position, the collar (70) is able to be moved between said unarmed and armed positions and actuation of the firing pin is inhibited. When the collar (70) is in the armed position and the safety interlock (92) is in the firing position, actuation of the firing pin is enabled.

Abstract

A diversionary device has a housing containing a pyrotechnic cartridge (24) with an ignitable fuse (52). A firing arrangement includes an ignition cap (60) containing a primer charge (54). Passageways (74, 82) in the housing and ignition cap define a first flow path from the primer charge to a region of the housing in which the fuse (52) is located through which flash from the primer charge can flow to ignite the fuse (52). A further flow path connects said region of the housing with the exterior of the housing to supply the fuse with oxygen for reliable burning. The device may be a multi-burst device containing a plurality of cartridges (24) and the first flow path may include a flash divider (86) for directing a proportion of the flash from a primer charge on to the fuse (52) of each cartridge. The housing may be separable to allow replacement of the cartridges (24).
