Abstract: A pneumatic gun sized and designed to appear like and operate in a manner similar to a conventional handgun. The gun may include a removable magazine storing projectiles and propellant. The entire magazine may be small enough to fit into a handle of the gun (e.g., with a pistol grip). The magazine may be integrated with propellant and projectile portions locked together or separable. Standard carbon dioxide cartridges fit within the magazine. Projectiles may be staggered to increase the maximum magazine load. A user may selectively release just the projectile portion of the magazine, in order to leave the propellant undisturbed until fully expended. The magazine may be completely removed from the gun without substantial loss of propellant.

Abstract: A paintball gun is sized and designed to appear like and operate in a manner similar to a conventional gun. A dual-action firing bolt moves forward, assisting in launching a projectile, under cast pressure. The bolt then releases the compressed gas to carry the projectile down the barrel. Return springs operate to move the bolt and its valves to a ready-to-fire position. Similarly, trigger actuation mechanisms are spring-actuated to return to the ready-to-fire position. A removable magazine stores projectiles and propellant. The magazine is small enough to fit into a handle of a pistol. A user may selectively release just the projectile portion of the magazine, in order to leave the propellant undisturbed until fully expended. The magazine can be completely removed without substantial loss of propellant.

Abstract: A continuously variable transmission that comprises an input shaft to which torque may be applied, an adjustable gearing mechanism, and a driven element. The adjustable gearing mechanism is attached to the input shaft and is configured to continuously vary the drive ratio in response to the applied torque transmitted through the input shaft. The adjustable gearing mechanism includes a hub operatively connected to said input shaft, resilient arms, and an engaging portion. The resilient arms are attached to the hub. In one embodiment of a continuously variable transmission, the hub and the plurality of resilient arms are integrally formed so as to form a one-piece member. The resilient arms are configured to continuously adjust the outer diameter formed by the resilient arms. The engaging portion is integral with each of the resilient arms and is configured to cooperate with an endless member such as a chain. The driven element is operably connected to said gearing mechanism by the endless member.
