    摘要: A method and apparatus for fast filling a vehicle fuel tank with high pressure natural gas comprising the steps of coupling a fill line to the vehicle tank, introducing high pressure natural gas into the line and the tank, measuring the pressure in the line in a manner that yields a measurement of the initial pressure of the gas in the tank, assigning an initial temperature for the gas in the tank, predetermining the final desired pressure and temperature of the gas in the tank at the end of the fill, calculating the mass or temperature of the gas to be added to the tank so that the adiabatic compression and potential rise in temperature of gas in the tank is automatically compensated for and the tank is substantially filled with a mass that results in a condition, when the tank and the gas contained therein substantially reach ambient temperature, wherein the pressure in the tank is substantially equal to the nominal rated pressure of the tank and, thereafter filling the tank with the calculated gas mass or temperature.

    摘要: Portable emergency breathing apparatus is disclosed which is comprised of a compressed breathing gas container having a housing mounted on the open end thereof which supports a pressure gauge, a pressure reducing valve assembly, and burst valve, fill valve and needle valve components. The pressure reducing valve controls the flow of breathing gas from the container to a breathing hose attached to the housing and leading to a face mask or hood worn by the user. The housing has a flat axially outer end relative to the container and a radially outer periphery which is within the cylindrical plane of the side wall of the container, and the housing is structured for mounting on the container so as to optimize compactness of the apparatus and protection of the pressure gauge and the pressure reducing, burst, fill and needle valves from damage during storage and use. A modification of the housing enables the apparatus to include two or more compressed breathing gas containers in side-by-side relationship, thus to increase the duration of use of the apparatus.
