| 41 | Firearm cartridge having a plurality of ignition primer chambers and associated methods for reducing the likelihood of misfire and cold shot and enhancing rapid and reliable firing | US09952634 | 2001-09-12 | US06502514B1 | 2003-01-07 | Christopher A. Holler |
| A multi-ignition cartridge and associated methods for use with a firearm are provided. The cartridge preferably includes a casing having an interior cavity which at least partially encloses at least one projectile. Chances of misfire and cold fire are substantially reduced by including in the casing a plurality of chambers. Each of the chambers preferably is in fluid communication with the cavity and containing an ignitable substance to ignite a main charge in the casing to propel the projectile from the casing. The ignitable substance in a chamber is ignited by striking a strike plate that can be positioned in contact with the casing. Related methods are provided for propelling the projectile of a firearm by simultaneously increasing pressure in multiple chambers of a cartridge casing so as to ignite in at least one chamber the ignitable substance contained in each so as to ignite a main charge that propels the projectile. | ||||||
| 42 | FIREARM WITH AN EXPANSION CHAMBER WITH VARIABLE VOLUME | US09444508 | 1999-11-22 | US20020053280A1 | 2002-05-09 | SALVATORE TEDDE |
| Improvement to firearms suitable for utilization with different types of ammunition, in conditions of absolute safety, said firearm comprising an expansion chamber (10) that communicates with barrel (1) of the firearm through at least one connecting hole (14), a front and back calibration screw (13, 12), for increasing the volume available to the expansion of combustion gases. Said hollow expansion chamber (10) is located in the lower back part (9) of the barrel (1), (or possibly in its upper part, in parallel to it); said expansion chamber (10) being equipped with an internal threading (11) which is capable of engaging itself to back calibration screw (12) in the distal back part, and a further calibration screw (13), which can be manually operated by a threaded knob (13a), located in the front part. | ||||||
| 43 | Augmented service pistol and ammunition weapons system | US177985 | 1994-01-06 | US5479736A | 1996-01-02 | David J. Forrester |
| An augmented service pistol weapons system and ammunition has an extended barrel and an adapter sleeve and mount which supports the barrel and partially surrounds a forward end of the service pistol. Two hinged flaps have inward extending clamps which engage an inside of the front of a trigger guard on the pistol. A turn-to-release locking pin holds the two flaps together as the flaps are closed on the trigger guard. An arm rest extends laterally rearwardly along sides of the pistol and terminates in a curved rearward extension to support the augmented service pistol on an arm of the user. A fifty round magazine replaces the standard pistol handle magazine. Scopes and aiming devices are mounted above the extended barrel. A foregrip is removable and positionable at opposite lateral sides of the extended barrel and below the barrel. A variable power function assembly surrounds the barrel and allows selected release of gas to slow projectiles. A shredding device near the muzzle shreds bands on the projectile. A valve on the variable power adjustment releases propellant gas from the barrel and sends the propellant gas forward to the flash suppressor on the muzzle. A shredder immediately before the flash suppressor extends blades and points into the barrel to shred rings which hold submunition segments and deployable air brakes in a projectile. A case which is attachable to a service belt holds the mount and extended barrel and scope and aiming devices, and three fifty round magazines, for rapid attachment to a service pistol. | ||||||
| 44 | Armored vehicle with a laterally alignable mortar | US34046773 | 1973-03-12 | US3818794A | 1974-06-25 | MAYER C; BURKHART R |
| An armored vehicle with a laterally alignable mortar which can be operated by a gunner or firing personnel and encompassing launching barrels each possessing a propellant charge chamber for shells loaded at the muzzles. The launching barrels are rigidly mounted at a laterally alignable turret housing which houses the firing personnel or gunner of the armored vehicle. The muzzles of the launching barrels are located at the wall of the turret. An annular compartment concentric to the axis of rotation of the turret and accommodating an infeed or delivery mechanism for the shells stored in magazines is arranged about the turret and protected by a hood. The magazines are movable relative to the turret by means of the infeed mechanism into a position in alignment with the launching barrels.

| Methods, systems, and devices to shape a pressure*time wave applied to sniper and dangerous game rifle projectiles whereby an ammunition shell casing's volume, at release of the projectile from the casing, and rifle system impedance (Z) in conjunction with the amount of propellant are modulated to beneficially shape the wave applied to the projectile's base, and by Newton's 2nd law the projectile's applied acceleration*time impulse wave, to reliably reduce the velocity of a sniper or dangerous game rifle's ammunition to a sub-Mach 1 level, preserve the projectile momentum, maintain the rifle's automatic shell casing ejection and new shell casing/projectile re-load action and maintain a projectile and rifle operation within their material's strength limits. These tools are further applied to simulate severe g acceleration environments for commercial and military weapon sub-system component's non-destructive testing and certification that are carried in a projectile and applicable to any existing propellant launcher/gun system. | ||||||

| A launcher system includes a launcher having a sealed breech and a barrel adapted to receive a projectile with a charge of propellant and a mechanism to vary the launch velocity by selectively controlling the propellant gases vented out of the projectile and into the barrel. A collar can be repositioned through rotation or sliding movement to selectively allow propellant gases to vent out of the barrel or stop propellant gases from venting out of the barrel. When the collar is in a closed or non-venting configuration, propellant gasses build-up pressure behind the projectile, resulting in a relatively high launch velocity and, when the collar is in the open or venting configuration, a relatively low launch velocity is produced. A sliding breech face and energy-absorbing plug can also be provided to further decrease launch velocity. | ||||||

| A system to acquire, via sensor data, and correct the trajectory of a fired bullet before it leaves the fire arm by directing the bullet exhaust gases via actuated gas ports, located on and in the compensator, to the corrected orientation as determined by the sensor data. Furthermore sensor data is additionally taken after the firing of the bullet to update future corrections. This system would be attached or wholly integrated into conventional small arms to create a quick target acquisition and firing correction system for the fire arm operator. | ||||||

| A cartridge has a shell casing with a primer end and a projectile end. A projectile mounted in the projectile end is made of four segments held together by first and second retainer rings. In one form each segment contains shot. One form of the projectile has an air brake which is deployed as the projectile leaves the muzzle. The air brake is partially deployed or fully deployed, depending of the shredding of third and fourth retainer rings which hold the air brake. When the shredder is inserted in a barrel in a first position, the last horizontal retainer ring is shredded and the air brake is partially deployed. When the shredder blades are further positioned in the barrel, both retainer rings which hold the air brake are shredded and the air brake is fully deployed. Additional positions of the shredder ring first shred the second ring, releasing the segments, and then shred the first retainer ring, releasing the shot and other contents from the segments. | ||||||
