An object of the present invention to provide a gas supply device, a gas supply device having a mixing function, a welding device, and a gas supply method, which can prevent rush flow of gas from the gas supply source in the initial stage of gas lead-out from a gas supply source, reduce the cost, and improve the maintenance; and the present invention provides a gas supply device including a gas supply source into which a gas is filled at a high pressure, a single-stage decompressor which is provided at a gas outlet of the gas supply source and which is configured to reduce pressure of a gas led out from the gas supply source to a predetermined pressure, a gas supply line having one end connected to the single-stage decompressor and the other end connected to a use destination of the gas, a solenoid valve provided in the gas supply line, and a flow regulating valve provided in the gas supply line located between the solenoid valve and the use destination.

A confinement article for containing a fluid includes a wall and a nano-aligned barrier. The wall is constructed and arranged to contain the fluid. The nano-aligned barrier co-extends with the wall, and is constructed and arranged to restrict permeation of the fluid.

Gas dispensing control systems that use a gas expansion chamber with a plunger in fluid communication with both a vacuum pump and a nitrogen supply with a controller that calculates and dispenses standard volumes of gas based, at least in part, on local environmental conditions. The dispensed gas can be hyperpolarized .sup.129Xe for MRI imaging.

Provided is a configuration in which the user can supply power to the gas remaining amount measurement module in the gas storage container at their own place. A gas storage container according to the present invention includes: a casing with a flat upper surface and a flat lower surface and is vertically stackable; a gas container installed in the casing; and a gas remaining amount measurement module including a power receiving member for a contactless power supply. The pedestal according to the present invention includes: a bottom portion for resting the gas storage container, the bottom portion being configured to contact the lower surface of the casing; and a side portion for supporting the gas storage container, the side portion including at least one power supplying portion with a power supplying member corresponding to the power receiving member.

A cryogenic dewar may include an inner tank and an outer tank. The cryogenic dewar may further include one or more longitudinal stiffeners coupled to the inner tank at locations of stress that provide resistance to such stress. The inner vessel may include a combination of longitudinal stiffeners to allow the dewar to meet governmental imposed regulations on strength and safety of the dewar without increasing the weight of the dewar or to increase the amount by weight of cryogenic liquid that can be transported under governmental imposed regulations, or both, by, with the addition of longitudinal stiffeners, simultaneously increasing the grade of the material of the inner tank.

Gas pressure actuated fill termination valves for cryogenic liquid storage tanks and storage tanks containing the same.

A tank includes a liner including an inner shell; and a reinforcing layer covering an outer surface of the liner; wherein the reinforcing layer is formed by continuously winding resin-impregnated fiber bundles around the liner, the reinforcing layer includes a hoop layer placed in a side of the liner, and a helical layer, gaps are formed between adjacent bundles of the resin-impregnated fiber bundles wound in the hoop layer, there is at least one site where the resin-impregnated fiber bundles are wound without forming a gap between adjacent bundles in the helical layer, and resin in the resin-impregnated fiber bundles has a resin toughness value of not less than 1.0 MPa.Math.m.sup.0.5.

cryogenic vessel includes a shell, an inner vessel and a thermal insulation layer arranged on a periphery of the inner vessel, a gap is provided between the shell and the inner vessel to form a sandwich space in a vacuum environment. The pressurizing device includes a fixing member, a protruding member, a heat conducting member, an operating member and a connecting member.

A method of and apparatus for transferring gas. The method comprising expanding a process gas 101 having a first temperature to produce a first volume of the process gas that has a second temperature that is greater than the first temperature, and a second volume of the process gas that has a third temperature that is less than the first temperature. The method further comprises displacing at least some of the second volume of the process gas 102 into the receiving vessel using a piston gas, wherein the piston gas is of the same type as the process gas.

Disclosed is a method and system that compresses ionized gas is stored in at least one containment cell. The compressed ionized gas is transferred from the at least on containment cell to an expansion chamber in which a piston is situated; The piston moves based in part on a reaction between ionized gas in the expansion chamber and an electrical charge of a surface of a head of the piston. The movement of the piston drives a drive shaft. Movement of the drive shaft is converted to electrical energy.
