摘要:
A system and method for launching projectiles, such as fireworks projectiles, which explode in the air into a pyrotechnic display. The projectile includes a shell constructed from a binding agent and an explosive additive which explodes the shell into small particles. The explosive additive, which may be nitrocellulose, causes the exploded particles to be rapidly burned and consumed to form lightweight, inert flakes that fall harmlessly to the ground. The projectile is aimed and launched by a launcher using a compressed gas to rapidly expel the projectile from a launching tube. Once in the air at a predetermined location in the sky, an electronic fuse inside the projectile operates to detonate the projectile into its intended pyrotechnic display. The fuse is extremely accurate and enables detonation of the pojectile at precise altitudes. An electronic control system controls launching and detonation of the projectiles in a precise and repeatable manner.

A pump action firearm includes a barrel (12) and a chassis (14, 94) defining a magazine well (28) for receiving a magazine (30). The magazine well extends longitudinally parallel to the barrel and contains a plurality of cartridges (32) arranged in stacked relationship with each cartridge having its longitudinal axis extending substantially transversely to a longitudinal axis of the barrel. A pump member (16) displaces the barrel forwardly and rearwardly. A carrier mechanism (44, 46, 106, 108) is linked to the pump member and, during pumping of the pump member, moves an end cartridge contained in the magazine from its stacked position to an operative position in alignment with the longitudinal axis of the barrel.

Dispositif de tir comprenant une arme à feu qui comprend des moyens pour amener une cartouche dans le chargeur devant l'entrée du canon et en appui contre un élément d'appui de la carcasse qui comprend le mécanisme de mise à feu et que le canon est coulissant dans la carcasse jusque dans une position dans laquelle le canon vient en butée sous l'action d'un ressort de rappel contre la partie avant de la douille de la cartouche, et en ce que chaque cartouche est pourvue de moyens de propulsion pour, projeter la douille et le canon vers l'avant.
摘要:
A recoil control mechanism for a weapon which fires a projectile which is characterised by the generation of a forward counterforce to the rearward recoil simultaneously with absorption of rearward recoil force upon initiation of propoulsion of the projectile. The forward counterforce is generated by propelling a first mass forwardly upon firing the projectile and substantially simultaneously propelling a second mass rearwardly for absorbing some of the recoil force. In one mechanism (10), the first mass may be the weapon's barrel (12) and the second mass its breach block (14). Expaning gases (36) from detonation of propellant in cartridge (24) enter a reaction volume (28) between the barrel (12) and breech block (14). These gases drive barrel (12) forwardly against force transmission spring (16) to impose a forward counterforce on the weapon's frame (18). Substantially simultaneously recoil from detonation of cartridge (22) together with the gasses (36) in reaction volume (28) drive breech block (14) rearwardly against force absorbing spring (20).

Eine Schußwaffe (10), insbesondere eine Repetierbüchse, hat einen Schaft (11), einen relativ zu dem Schaft (11) an oder in einer Linearführung (20) axialverschieblich gelagerten Lauf (30), in dem ein Patronenlager (31) zur Aufnahme einer Patrone (P) ausgebildet ist, eine Verschlußvorrichtung (40), die zum Verschließen des Patronenlagers (31) einen Verschlußkopf (41) aufweist, der beim Schließen der Waffe (10) axial im Laufende (32, 33) festlegbar ist und der zentrisch zur Laufachse (A) von einem Schlagbolzen (18) durchsetzt wird, und eine Verriegelungseinrichtung (80) zum Verriegeln der Waffe (10) in Schließstellung. Die Verschlußvorrichtung (40) ist im wesentlichen axialsymmetrisch und/oder rotationssymmetrisch zur Laufachse (A) ausgebildet. Sie weist zur Festlegung des Verschlußkopfs (41) im Laufende (32, 33) radiale und/oder radial wirkende Verschlußorgane (60) auf, die durch Längsbewegen des Laufs (30) mit korrespondierenden Verschlußelementen (65) im Laufende (32, 33) in Eingriff bringbar sind. Der Verschlußkopf (41) ist axialverschieblich und/oder drehbar an einem koaxial zur Laufachse (A) ausgebildeten Träger (50) gelagert, der ortsfest an oder in einem fest mit dem Schaft (11) verbundenen Gehäuse (90) angeordnet ist. Die Verriegelungseinrichtung (80) ist bevorzugt im Bereich der Verschlußvorrichtung (40) ausgebildet.
