Abstract: A water-rocket water-transfer-station, referred to as the water station, is comprised of a specialized manifold combined with a plastic carbonated drink bottle, which functions as a water reservoir. The water reservoir is pressurized with air to make a water transfer station for water rockets. By using pressurized air, water can be transferred from the water station to a water rocket launch system, referred to as the launcher, and into an attached water rocket. A second unique feature of this system is the ability to return water from the water rocket back into the water station reservoir, as in the case of an over-fill, or in a launch abort. This unique water station can easily and quickly transfer water to a water rocket from a water reservoir, and in reverse from a rocket, without having to remove the rocket from the launcher. This saves time and minimizes water waste which is important when water has to be hand carried into a remote launch field.

Abstract: A projectile (10) arranged to be launched from a launcher (12), the projectile comprising a source of compressed gas (1) and control means (23) for controlling the release of the compressed gas, in which the control means (24) is arranged so as to release the compressed gas in response to the launching of the projectile (10) from the launcher (12). Typically, the control means (24) is a valve, arranged such that the application of gas pressure from the launcher (12) is required in order to release the compressed gas, but the application of gas pressure must abate before the compressed gas is released. Thus, the compressed gas may only be released once the projectile (10) has cleared the launcher (12).

Abstract: A projectile assembly that enables a compressed gas powered projectile to be fired from a traditional ammunition firearm. The projectile assembly includes a casing that is shaped like the casing of traditional ammunition. A projectile is set into the tip of the casing. Within the casing is located a compressed gas cartridge. The projectile assembly is loaded into the breech of a traditional firearm.

The gas pressure displaces the projectile from the tip of the casing and propels the projectile down and out the barrel of the firearm. The casing is designed so that a new compressed cartridge can be placed in the casing and the projectile replaced.

Abstract: The present invention is a self-propelled arrow, consisting of an otherwise conventional hunting or target practice arrow that is propelled by CO2 and water, thus providing additional thrust to the arrow when shot from a bow. String inertia causes a CO2 filled cartridge to strike the point of a puncture means which punctures the cartridge and releases charged CO2 into a water storage chamber which charges the water inside. The charged water becomes pressurized and actuates a pliable closure membrane to an open position in check valve fashion, thus releasing the pressurized water from the water storage chamber through the propellant jets in the rear of the arrow. This system accelerates the arrow and decreases the arrow drop, thereby increasing the range and speed of the arrow immensely. The CO2 cartridges may be replaceable.

Abstract: A cartridge has a case comprising a body housed telescopically within a sleeve. The body encloses a main chamber which contains gas under pressure, and a valve mechanism for venting gas from the chamber into an expansion chamber. The pressure of the gas in the expansion chamber causes the body to move rearwardly relative to the sleeve to apply a force to the breech block of the weapon in which the cartridge is used, thereby to initiate the reloading cycle. Gas is vented from the expansion chamber to eject a projectile when a spigot projecting from the body is withdrawn from an aperture in the end wall of the sleeve.

Abstract: A simulated weapon includes a pressure switch within the simulated weapon's barrel. The pressure switch responds to pressure changes within the weapon barrel to activate a light emitter. In response, the light emitter emits a beam of light that simulates weapon fire by indicating the aim of the simulated weapon. Pressure changes within the barrel are induced by a conventional air cartridge that emits a blast of air when struck by the firing pin of the simulated weapon. The user can thus produce the simulated fire by activating the simulated weapon's trigger to trip the hammer and drive the firing pin into the air cartridge. In another embodiment, the simulated weapon activates a nonlethal pyrotechnic round. Simulated fire is produced in response to detection of the recoil, force, or pressure change produced by the pyrotechnic round. The simulated weapon may be a pistol, rifle or any other conventional hand held weapon.
