81 Electronically controlled fire-arm using liquid propellant EP01204189.3 2001-11-02 EP1219914A2 2002-07-03 Barattieri di San Pietro, Simone

Firearm similar to a rifle, of innovative conception. It uses projectiles without casings, and explosive liquid. The sequence of all the operations is governed electronically by a microprocessor, an electric motor turns the cylinder, a pressurised tank feeds the firing chamber and a sparking plug ignites the explosive.

The firearm is very simple, it does not require complex mechanical parts, it is completely sealed and after use it is not used again (disposable) in that the remaining parts are of very little value. It can be made very easily, but only by those who are knowledgeable in electronics.

It has sufficient firing autonomy and may be seen above all as a self-launching magazine.

93 Dispositif d'éjection au moyen d'une charge propulsive liquide d'un projectile placé dans un tube de lancement EP87402091.0 1987-09-18 EP0262037A1 1988-03-30 Poussard, Jean-Marie

Le dispositif possède des moyens de chargement pour amener la charge liquide dans une chambre de combustion pour la faire déflagrer et provoquer l'éjection du projectile. Avant le tir, cette charge est stockée dans une chambre réservoir délimitée par le tube, un piston coulissant à l'intérieur de celui-ci et dans une butée placée dans le tube. La position initiale du piston est réglable à l'avance à l'aide de moyens de réglage commandés de l'extérieur. La détente des gaz issus de la cartouche du projectile provoque la montée en pression dans la chambre de combustion, et la pénétration du liquide contenu dans le réservoir à travers le piston qui descend alors dans la butée (5). Le liquide pénètre dans la chambre (1) et déflagre,

94 In-line annular piston fixed bolt regenerative liquid propellant gun EP84112793.9 1984-10-24 EP0140332A1 1985-05-08 Magoon, Inder Kumar

A regenerative liquid propellant gun structure in which the differential area piston (6) is annular, having a peripheral cylindrical skirt (63) extending away from the combustion chamber (36) to define a propellant reservoir (35), and has an aperture (62) permitting overrunning of a fixed bolt (5). The fixed bolt (5) is shaped to define with the edge of the aperture (62) a variable annual orifice for propellant injection as the piston (6) moves. There is a second free piston (7) overrunning the bolt (5) and mating with the inside of the differential area piston (6) to complete and provide for emptying of the reservoir (35). The structure also contains a spring (46) to allow components to move responsive to increased combustion chamber pressure to provide for an initial movement of differential area piston (6) relative to the bolt (5) to start propellant injection and a fluid pressure means for movement of pistons (6, 7) after firings to facilitate reloading.

Eine Feuerwaffe ist mit einer Ansaugleitung ausge stattet, um herkömmliche Treibstoffe (Flüssiggas od. dgl.) als Treibmittel verwenden zu können. Ein beweglicher Teil der Waffe dient als Verdichterkolben und/oder zum An trieb desselben. Ist der Lauf selbst verschiebbar, so kann an ihm gleich auch der Ladeverschluß ausgebildet sein. Der Ladeverschluß kann aber auch durch den Gasdruck betätigt werden. Statt eines Verdichterkolbens ist die Waffe auch mit Hilfe einer Einspritzpumpe betreibbar. Um ge genüber dem Treibmittel eine gute Abdichtung im Geschoß lager zu erzielen, werden die Geschoße mit einer Kunst stoffhülle überzogen, die gegebenenfalls kettenartig gleich eine Anzahl von Geschoßen, allenfalls samt zugehöriger Treibmittelmenge, umfassen kann. Hiezu sind in der Waffe eine Trenn- und eine Fördereinrichtung vorgesehen.

97 APPARATUS AND METHOD FOR FIRING A PROJECTILE PCT/US2005028727 2005-08-12 WO2006020861A3 2007-06-07 TIPPMANN DENNIS J SR; TIPPMANN DENNIS J JR
Apparatus for firing a projectile comprises a receiver, a barrel, a supply of combustible gas, a combustion chamber, a valve arrangement for controlling flow of combustible gas from the supply to the combustion chamber, an igniter, and a passageway for directing combustion gases from the chamber to propel a projectile from the apparatus. In one embodiment, the barrel has a longitudinally-extending central axis, and the combustion chamber is disposed laterally adjacent the axis. A method of operating the apparatus comprises the steps of providing a combustible mixture of gas and air to the combustion chamber, igniting the mixture so as to generate combustion gases, allowing pressure in the combustion chamber to increase to a predetermined level, and releasing the gases from the combustion chamber and directing the gases to propel the projectile through the barrel.
98 AUTOMATIC FIREARM SHOOTING SHELL-LESS AND POWDERLESS CARTRIDGES PCT/EP9001237 1990-07-30 WO9105980A3 1991-10-31 GHIOTTO GIANNINO; GHIOTTO GIUSEPPE
The invention discloses an automatic firearm, suited to shoot shell-less and powderless cartridges, and wherein the thrust of the projectile (18) through the rifled barrel (2, 302) is obtained by the blast of an air/combustible mixture, under super critical conditions, within an explosion chamber (7). According to a preferred embodiment of the invention, the explosion chamber (7) receives heated and compressed air and combustible under such conditions as to cause the blast with or without the lighting of a spark in the interior of said explosion chamber. According to another embodiment of the invention, the super critical conditions of the air/combustible mixture are created within an explosion chamber, having a volume which varies according to the stroke of a sliding piston within a cylindrical body. When the volume of the explosion chamber reaches the minimum, the mixture explodes.

100 RAM ACCELERATOR SYSTEM WITH BAFFLES EP16783882 2016-04-21 EP3286401A1 2018-02-28 RUSSELL MARK C; ELDER TIMOTHY JOHN; WOLFF JONATHAN M
One or more ram accelerator devices may be used to form one or more holes in geologic or other material. These holes may be used for drilling, tunnel boring, excavation, and so forth. The ram accelerator includes one or more baffles that are downhole. The ram accelerator devices propel projectiles which are accelerated by combustion of one or more combustible gasses in a ram effect to reach velocities exceeding 500 meters per second. An endcap may be deployed within a tube of the ram accelerator device to prevent incursion of formation pressure products such as oil, water, mud, gas, and so forth into a guide tube of the ram accelerator. The endcap may be maintained in place within the hole at least in part by the one or more baffles. During operation the projectile penetrates the endcap and at least a portion thereof impact a working face.
