20130256026 | Adjustable Box Extender - An adjustable box extender allows an electrical device to be aligned with a dry wall face. The adjustable box extender includes a fixed ring attached to an electrical box and an adjustable ring adjustably attached to the fixed ring. The adjustable ring includes rectangular top and bottom open back pockets. Rectangular blocks reside inside each pocket. Adjusting screws are held by the adjustable ring with screw heads exposed on the face of the adjustable ring, neither advancing nor retreating with respect to the adjustable ring, and free to rotate with respect to the adjustable ring. The screws engage threads in the blocks and advance and retreat the block out of and into the pockets when the screws are turned, thereby extending the adjustable ring away from the fixed ring to adjust for dry wall thickness. Electrical device screws sandwich the adjustable ring between the electrical device and the fixed ring. | 10-03-2013 |

20090301738 | PORTABLE FIRE EXTINGUISHING APPARATUS AND METHOD - A fire suppression device including a fire suppression agent generator. The device further includes trigger mechanism adapted to begin generation of the fire suppression agent from the fire suppression agent generator A container at least partially surrounds the fire suppression agent generator and the trigger mechanism, the container includes a discharge port that directs fire suppression agent in at least two opposed directions. In one example, the discharge port extends substantially around a perimeter of the container | 12-10-2009 |
20100147177 | Fluid energy delivery burst cartridge - A modified fluid delivery cartridge. A conventional straight-sided high pressure cartridge case is primed and then filled with solid propellant. A burst cup is inserted in the case mouth. The burst cup is preferably embossed with a cross or other shape to promote predictable rupture. A charge casing is provided which opens into a high pressure cartridge receiver bounded by an inner charge casing wall. The inner charge casing wall is provided with a step, in which the diameter of the high pressure cartridge receiver is reduced. The high pressure cartridge case is pressed into the receiver in the charge casing wall. As the high pressure cartridge case is being pressed into place, the straight wall of the case passes over the step in the inner charge casing wall, which deforms the straight wall to form a neck. This neck captured the burst cup within the high pressure cartridge case. | 06-17-2010 |
20100212529 | Drag minimizing projectile delivery system - A modified cartridge assembly including a projectile having a gas generator proximate its aft end. The projectile includes an aft closure having a cavity filled with gas generating material. The gas generating material is ignited around the time the projectile exits the weapon's muzzle. The gas generating material then burns while the projectile is in flight, spewing pressurized gas into the wake region immediately behind the projectile. The pressurized gas reduces the projectile's base drag. | 08-26-2010 |
20100242773 | PROJECTILE 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 |

20110174187 | Door breaching projectile system - A modified 40 mm grenade round designed to breach doors without throwing a substantial amount of shrapnel into a building's interior. The modified round includes a standoff device located on its forward end. The standoff device detonates the explosive charge within the projectile before the nose of the projectile actually strikes the target. This early detonation throws a pressure wave again the door's exterior, forcing the door inward. Shrapnel produced by the detonation remains primarily outside the door. Thus, the modified projectile is able to blow open a door without throwing a significant amount of shrapnel into a building's interior. | 07-21-2011 |
20120216698 | Low Shrapnel Door Breaching Projectile System - A modified 40 mm grenade round designed to breach doors without throwing a significant amount of shrapnel into a building's interior or back toward the shooter. The modified round includes a forward extension on the ogive. The extension is rigidly connected to a thrust column which transmits an impact load directly from the ogive's nose cap to the striker on the fuse assembly. This configuration detonates the explosive charge within the projectile while the explosive is still well outside the door. This early detonation throws a pressure wave again the door's exterior, forcing the door inward. | 08-30-2012 |
