| Number | Title | Issue Date |
| 7398614 | Firearm apparatus and method A firearm apparatus and a method of firing ammunition therefrom, where the method utilizes a barrel (12) having a breech end surface (40) and immovably affixed to frame (10), a stand pressure surface (32), and a cartridge container (16... | 07/15/2008 |
| 7353739 | Arrangement for weapon An arrangement for a weapon including a countermass for reducing the pressure around the weapon. The countermass is enclosed in a countermass container that can be opened at both ends. The invention aims to bring about a symmetrical opening with favorable recoil in ... | 04/08/2008 |
| 7305911 | Method and device for launching free-flying projectiles The present invention relates to a method and a device by means of which it has been made possible, without gas discharge to the surrounding environment, to accelerate the speed of a powder-gas-driven projectile from zero to a speed which gives the projectile free-f... | 12/11/2007 |
| 7302773 | Method of firing of firearms A method of firing of arms which utilizes both action and reaction forces in the process of firing. The action force propels the projectile (14) while the opposite in direction reaction force is used with an independent freely moving inert mass (20) in... | 12/04/2007 |
| 7191693 | Arrangement for weapon An arrangement for a weapon including a countermass for reducing the pressure around the weapon. The countermass is enclosed in a countermass container with an openable cover provided with break indications. The arrangement brings about a symmetrical opening operati... | 03/20/2007 |
| 6971299 | Countermass weapon The subject invention concerns a general method of producing countermass weaponry and is based on the use of a high-pressure system and a low-pressure system with a countermass (12, 26, 26′, 38) acting against the low-pressure system. The high-pressure syst... | 12/06/2005 |
| 6964220 | Floating barrel handgun method of recoil elimination A floating barrel gun design, a design in which a propellant gas discharge is used to counterbalance the recoil force of the gun, has been improved to include a novel automatic mechanical mechanism which allows the floating or inner barrel to be held stationary with... | 11/15/2005 |
| 6951070 | Defense device, preferably self-defense device and storage unit used therein A storage unit includes a nozzle unit, a storage space holding an active substance, an openable closure element sealing the storage space, a store output that includes the nozzle unit and a nozzle entry space having a circumferential inner wall arranged between a no... | 10/04/2005 |
| 5952601 | Recoilless and gas-free projectile propulsion A recoilless and gas-free projectile propulsion device is provided. A hol pressure vessel is sealed on a first end to an aft end of a projectile in a launch tube. The pressure vessel is further open on a second end. A propellant charge-filled pressure ch... | 09/14/1999 |
| 5900575 | Bottom plate member The invention relates to a bottom plate member (6) which is designed and made for initially tightening a chamber in which a high gas pressure is generated, for example the propellant charge chamber (4) in an ammuniton round for a recoilless weapon system ... | 05/04/1999 |
| 5216194 | Lightweight molded cartridge case and nozzle assembly for recoilless launch systems A cartridge case and nozzle assembly is made from a single element of a lightweight durable polymer resin. The cartridge case and nozzle insert into a launch tube of an anti-armor projectile launcher and have improved adhesive connection to reduce relativ... | 06/01/1993 |
| 4452123 | Composite round/rapid fire gun A rapid fire gun round is made with a composite chamber. The chamber is led by rotational motion rather than by reciprocating motion. The round will work in a recoilless gun configuration. An alternate arrangement permits multiple barrels to be arranged ... | 06/05/1984 |
| 4208948 | High efficiency propulsion system A high efficiency propulsion system for launching a rocket or projectile h higher delivered specific impulse than can be delivered with a given propellant using a conventional rocket or recoilless gun and still maintain a recoilless launch condition.... | 06/24/1980 |
