Abstract: Aspects of the invention include methods for producing purified semiconductor or metallic materials. In one embodiment, the methods include admixing a particulate composition of a material, for instance, a metal, with a metal halide to produce a metal-metal halide admixture.

Abstract: A closed bolt system with a trigger assembly for converting an open bolt, blowback type submachine gun into a single firing carbine is provided. The closed bolt system with trigger assembly includes a tensioned trigger member supporting a tensioned disconnector system. A tensioned sear interacts with the disconnector system and a tensioned hammer. The hammer strikes a firing pin in the bolt when it is released from the sear.

Only after releasing the trigger will the sear re-engage with the disconnector system and thereby permit another round to be fired. A receiver having a cavity encloses the bolt and prohibits a fully automatic bolt to be used therewith.

At high temperature, stop position, at which backward movement of the piston of the master cylinder is limited by an output member while a valve piston is at a non-operating position, is shifted forwards by a stop position shifting means, thus reducing the area with which the cylinder communicates with the port communicating with the reservoir and being open to the cylinder.

Abstract: An underground fuel tank releases vapors depending upon air pressure. A vapor pressure management system has a canister for a vapor recovery system that connects with piping from an underground tank and has carbon therein along with appurtenant pipes and valves. When an ORVR vehicle refuels, the pressure lowers in an underground tank that draws air through the valves into the canister. After refueling an ORVR vehicle, environmental conditions generate hydrocarbon vapors. Barometric pressure drops and evaporated fuel during long refueling lulls produce hydrocarbon vapors at an increased pressure. Those hydrocarbon rich vapors then return to the canister of the system where the carbon binds the hydrocarbons while releasing air to the atmosphere. The refueling of the next ORVR vehicle draws in atmospheric air to purge the hydrocarbons retained in the canister of the system.
