Abstract: A hydrogen-propelled projectile for using with a firearm eliminates cleaning the firearm and a method of making the projectile eliminates storing explosive propellant. The projectile has a cylindrical brass body closed at top and sealed at bottom with a primer and a brass seal. When the projectile is used with the firearm, the primer ignites hydrogen in the presence of oxygen, producing water vapor and energy that propels projectile toward a target. To make the projectile a salt water solution is electrolyzed to produce hydrogen and oxygen. A mixture of hydrogen and oxygen is then fed to a loader. The loader fills up the projectile, attached at a gas outlet, with gas by exerting pressure on gas using a load piston and channeling gas to the projectile. Finally, the loader seals the projectile with the primer by pressing a primer ram and affixing the primer at bottom of the projectile.

Abstract: A safety device for deflecting spent ammunition cartridge cases away from a rifleman as they exit the ejector port of a semiautomatic or automatic rifle. In a first embodiment, intended for use with a rifle from which the carrying handle has been removed from the rifle's upper receiver rail in order to mount a monocular night vision device or other rail-mountable device, the deflector includes a deflector plate pivotably attached to a base plate and movable between a lower, ejector port covering position and an upper, ejector port uncovering position. A thumb-screw adjustable clamp attaches a front end of the base plate to the rail. A rear wall attached to the base plate has a rocker arm mechanism for alternately capturing the deflector plate in the lower position and releasing it to move to the upper position. A second embodiment has two spaced-apart clamps attached to a base plate for attaching the deflector to a rifle's carrying handle, but is otherwise similar to the first embodiment.
