Abstract:
An overpressure safety apparatus having a fuel container body and a mounting cap includes a main housing coupled to the mounting cap, the main housing having an elbow-shaped gas introducing passage, a valve stem disposed in the main housing through the mounting cap. The valve stem is provided with an orifice, an opening/closing seal inserted between a top of the main housing and the mounting cap to selectively open/close the orifice of the valve stem. A sub-housing is connected to a bottom of the main housing, and has a branch line communicating with the gas introducing passage and a receiving cavity with a bottom communicating with the branch line and a top communicating with an exhausting hole formed on the mounting cap. A safety valve is disposed in the receiving cavity to selectively open the branch line in response to variations of internal pressure of the container.
Abstract:
A portable liquid oxygen medical delivery system including a portable liquid oxygen delivery apparatus and a portable liquid oxygen recharger. The portable liquid oxygen delivery apparatus contains an initial quantity of liquid oxygen. The liquid oxygen delivery apparatus is sufficiently lightweight for portability by an ambulatory patient and has a fill port for receiving liquid oxygen. The liquid oxygen recharger stores a supplemental quantity of liquid oxygen and is also sufficiently lightweight for portability by an ambulatory individual. The liquid oxygen recharger has an interface for interfacing the liquid oxygen recharger with the portable liquid oxygen delivery apparatus for delivering the supplemental quantity of liquid oxygen to the portable liquid oxygen delivery apparatus.
Abstract:
A valve device of a high-pressure tank for a vehicle has a valve box that is attached to the high-pressure tank and that houses a gas inlet opening, a gas outlet opening, a flow path connecting the gas inlet opening, the gas outlet opening and the high-pressure tank, and a valve disposed on the flow path. The gas inlet opening, the gas outlet opening, at least a portion of the flow path, and the valve are provided on a plane that intersects perpendicularly with an axis direction of the high-pressure tank.
Abstract:
A double-walled vacuum insulated container for holding a cryogenic fluid comprises a support system for the inner vessel that comprises at least one elongated metallic conduit that penetrates the walls of the outer vessel and the inner vessel. The conduit itself provides support in an axial direction parallel to a horizontal axis and at least two non-metallic members provide support in a radial direction from the horizontal axis. By requiring the conduit to support only axial loads, its wall thickness can be reduced, thereby reducing heat transfer through the conduit. The non-metallic members that provide support in the radial direction can be made from composite materials selected for structural strength as well as low thermal conductivity, resulting in a container with improved overall thermal insulation to reduce heat leak and allow longer holding times.
Abstract:
In a high-pressure gas tank for motor vehicles and a method for filling a high-pressure gas tank which has an interior space for holding gas and a filling region with an inflow opening which leads to the interior space, the filling region is formed so as to direct a gas jet which enters through the inflow opening at an angle φ upwardly with respect to a central horizontal longitudinal axis of the interior space toward a top wall of the tank where the gas jet is deflected toward the end of the tank opposite the filling region.
Abstract:
A pressurized gas container is provided with a rigid inner container and with a projectile-proof casing. The projectile-proof casing surrounds the inner container on the outside and is of an elastic material having a high tensile strength in the peripheral direction.
Abstract:
A storage vessel for storing a fluid substance, said storage vessel including a plurality of abutting individually sealed storage chambers, each chamber capable of withstanding super atmospheric pressure, with adjacent chambers forming at least one fluid passageway therebetween, characterised in that at least one said chamber includes an external peripheral seal configured to be relatively weaker than the remainder of said vessel.
Abstract:
A system for increasing the overall efficiency of a high pressure gas fueled vehicle and refilling station infrastructure wherein the compression heat of high pressure refueling of an on board tank is absorbed by a temperature dependent melting/solidifying media within the interior of an on board tank and may be dispersed through an external radiator.
Abstract:
A gas collection receptacle includes a segmented top portion and one or more side portions creating a volume for collecting gases. The gas collection receptacle, configured to float on a pond, lagoon, or other area, also includes interlocking side and end portions enabling multiple receptacles to connect, thus forming a substantially continuous covering.
Abstract:
The operability of a fuel cell which uses a fuel cartridge housing a liquid fuel is improved. A fuel cartridge 1400 houses a liquid fuel 124. The fuel cartridge 1400 includes a gas-liquid separation film 1408 which divides a fuel housing section 1402 into a liquid housing chamber 1402a and a gas housing chamber 1402b. A fuel gas, which is the vaporized liquid fuel, is housed in the gas housing chamber 1402b. A gas exhaust pipe 1410 is connected to the gas housing chamber 1402b, and the fuel gas housed in the gas housing chamber 1402b is discharged to outside the fuel cartridge 1400 via a gas discharge port 1414.
