Patent number: 7988381Abstract: A vehicle disabling apparatus may include at least one plunger assembly having a plunger and a toggle operable to pivot inside the vehicle tire. The apparatus may include energetic material disposed adjacent the plunger and configured to force the plunger into a vehicle tire. A method of disabling a vehicle having a tire may include using the vehicle's tire to move the plunger and thereby activate the energetic material; and moving the plunger into the tire using gas produced by the energetic material.Type: GrantFiled: September 9, 2008Date of Patent: August 2, 2011Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Albert Meyer-Pflug, Victor N. Kokodis, Frank Dindl, Warren G. Reiner, Jr., Michael Heayn

Patent number: 7418896Abstract: A recoilless weapon system is provided rear portion, a barrel in movable connection to the rear portion, and a handle portion in removable connection with the barrel and/or rear portion. Further, a ballast payload cartridge is removably disposed within a ballast payload cartridge portion of said rear portion, and serves as a center breach to support a combat cartridge. The ballast payload cartridge may have a side primer disposed therein, which allows a single weapon firing pin to simultaneously initiate both the combat cartridge primer and the ballast payload cartridge primer.Type: GrantFiled: March 14, 2005Date of Patent: September 2, 2008Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Frank Dindl, Kenneth R. Jones, Richard Beckman

Patent number: 7380488Abstract: A firing adapter for a combination gas and recoil operated weapon includes a blank firing barrel attached to the weapon; a piston having a barrel end and an anchor end, the barrel end being reciprocably disposed in the blank firing barrel and the anchor end being fixed to a non-recoil surface; and a gas port formed in the blank firing barrel wherein in a rest position of the weapon, the barrel end of the piston closes the gas port, and in a recoil position of the weapon, the barrel end of the piston opens the gas port.Type: GrantFiled: December 12, 2005Date of Patent: June 3, 2008Assignee: The United States of America as represented by the Secretary of the ArmyInventors: David C. C. Mao, Frank Dindl

Patent number: 7207276Abstract: A non-lethal ammunition utilizes dense powder ballast and a two-stage firing sequence for launching non-lethal projectiles of a caliber range from approximately 5.56 mm through approximately 40 mm. The non-lethal ammunition comprises a non-lethal cartridge. The non-lethal cartridge comprises a dense powder ballast and one or more non-lethal projectiles. The dense powder ballast is more massive than the non-lethal projectile providing sufficient payload mass to operate the weapon mechanism while launching the non-lethal projectile at velocities compatible with non-lethal applications. A two-stage ignition system fires the non-lethal ammunition and subsequently fires the more massive dense powder ballast. The firing events are separated by a time delay of less than a second. The non-lethal ammunition provides non-lethal projectile capability for semi-automatic and automatic weapons.Type: GrantFiled: August 25, 2004Date of Patent: April 24, 2007Assignee: United States of America as represented by the Secretary of the ArmyInventor: Frank Dindl

Patent number: 7055422Abstract: An improved Barrett anti-armor gun that is modified to function from the open bolt with advanced primer ignition, wherein the forward momentum of the recoiling masses at the moment of firing offset a significant portion of the recoil impulse from firing. The modification reduces the recoil energy absorbed by the shooter.Type: GrantFiled: September 7, 2004Date of Patent: June 6, 2006Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Frank Dindl, Sergio Aponte

Patent number: 6178889Abstract: A low impulse telescoping cartridge includes a case, a piston, a projectile, and a link. The projectile is seated into the forward portion of the piston. Gas passages permit propellant gases to bleed into the cavity behind the projectile and to accelerate the projectile upon firing. An alternative to using bleed gases is to use a separate propelling charge behind the projectile. The case and piston are assembled and telescopically secured by means of a crimp or other similar feature, to allow relative movement therebetween during chambering and firing. The link may be allowed to move for some portion of the required relative travel between the link and the base of the case. A shoulder on the piston provide a stop through which reaction loads are transmitted to the rear of the barrel during chambering and firing. The piston telescopes over the case during chambering to provide the relative movement between the link and the case base required for weapon function.Type: GrantFiled: July 12, 1999Date of Patent: January 30, 2001Assignee: The United States of America as represented by the Secretary of the ArmyInventor: Frank Dindl
