Patent number: 8720341Abstract: A multiple output and effect grenade is provided, in which an exothermic delay column is utilized to initiate a series of primers via the application of heat to the strike faces thereof, thereby providing a reliable and relatively safe grenade to ship and store. In particular, a multiple output and effect grenade comprised of an exothermic delay column disposed within a central cavity, operable to initiate a series of primers disposed in primer cavities located within the main body of the grenade. The primer cavities may be arranged in a symmetrical or asymmetrical configuration, so as to produce a firing signature resembling an automatic weapon or random gunfire, respectively. In addition, effect charges, such as illuminants, sound agents, chemical irritants, etc., may be disposed within the primer cavities, as desired by the user.Type: GrantFiled: January 17, 2013Date of Patent: May 13, 2014Inventor: Michael Brunn

Patent number: 7908972Abstract: A flare-bang projectile is comprised of a weighty ballast in the front leading edge, a flash-bang charge, a transfer charge and a flare charge that is lit by a starter composition located at the rear of the flare charge. When the flare charge is ignited such that it burns during the flight of the projectile, an the projectile path is indicated to thereby provide warning signaling.Type: GrantFiled: July 12, 2007Date of Patent: March 22, 2011Inventor: Michael Brunn

Patent number: 7866265Abstract: A flare apparatus constructed of a flare case with a primer functionally coupled to a propellant charge. Loaded within the flare case is a flare cup, having within, a starter composition, a flare composition, and a flash charge. The flare composition is functionally coupled to the flare starter composition, and the flash charge is functionally coupled to the flare composition. Upon primer activation the propellant charge is ignited. Flame and hot gasses from the propellant charge propel the flare cup out of the flare case and downrange while also igniting the flare starter composition within the flare cup. The flare starter composition ignites the flare composition, which produces a visual artifact and subsequently ignites the flash charge which produces a visual and audible artifact at or near the end of its flight.Type: GrantFiled: June 29, 2007Date of Patent: January 11, 2011Inventors: Jacob Kravel, Michael Brunn

Patent number: 7712418Abstract: A closure wad is placed at the mouth of the launching end of a shotgun cartridge before the mouth is crimped down to seal the launching end of the cartridge. Both the walls of the closure cap and the walls at the mouth of the plastic envelope are crimped down together, thereby forming a substantially impermeable seal at the launching end of the cartridge. In addition, the inventive closure cap substantially reduces the detritus which is sometimes expelled when a launcher cartridge is fired.Type: GrantFiled: December 5, 2008Date of Patent: May 11, 2010Assignee: Combined Systems, Inc.Inventor: Michael Brunn

Patent number: 7293492Abstract: In a multiple projectile launcher system, cartridges are securely held within a cassette that can be loaded into a locking and priming mechanism in a base of a multiple projectile launcher. Once the cassette is loaded into the locking and priming mechanism, the cartridges in the cassette may be primed by moving the locking and priming mechanism (which is holding the cassette) such that electric igniter contacts in the launcher base are in contact with electric igniters at the priming end of each cartridge. Once the cassette is locked (thereby priming the plural cartridges held in the cassette), the cartridges may be fired singly, severally, and/or all at the same time, using an electrically initiated fire control system. The multiple projectile launcher is particularly effective in crowd and/or riot control, where the payload of the cartridges comprise non-lethal and/or less-lethal munitions, such as tear gas grenades, sting-ball grenades, flash-bang rounds, bean bags, etc.Type: GrantFiled: October 7, 2004Date of Patent: November 13, 2007Inventor: Michael Brunn

Patent number: 7287475Abstract: A reloadable non-lethal training cartridge is provided comprising a cartridge case, a rear high pressure chamber removably disposed within the base thereof, and a non-lethal payload portion removably disposed adjacent the forward end of the cartridge case. The rear high pressure chamber is provided with a base capable of interacting with a removal tool, such as a hexagonal shaped base capable of interacting with a standard socket. Further, the non-lethal payload portion is comprised of a base and a non-lethal payload, the non-lethal payload and base being removably attached such that one or both of said components may be reused. In addition, the non-lethal payload may be weighted, so as to increase the accuracy thereof.Type: GrantFiled: January 3, 2006Date of Patent: October 30, 2007Assignee: Combined Systems, Inc.Inventor: Michael Brunn
