Abstract:
A cryogenic liquid stream from a storage tank to be pumped is passed through the heat exchanger located within a phase separator vented to atmosphere and a subsidiary cryogenic stream is divided out of the cryogenic liquid stream and is diverted to the phase separator prior to a pump. Low pressure maintained within the phase separator causes the subsidiary cryogenic stream to boil off and form a liquid fraction that covers the heat exchanger. The liquid fraction, which is at a sufficiently low temperature, subcools the cryogenic stream passing through the heat exchanger. Flow of the subsidiary cryogenic stream is suspended when the height of the liquid fraction reaches a predetermined level and is reestablished when the level falls due to boil off. During periods of suspended flow, flow is temporarily reinitiated to prevent the accumulation of warm liquid and vaporized liquid near or at the inlet to the pump.
Abstract:
A hydrogen storage and delivery system is provided having an orifice pulse tube refrigerator and a liquid hydrogen storage vessel. A cooling system, coupled to the orifice pulse tube refrigerator, cools the vessel and abates ambient heat transfer thereto in order to maintain the liquid hydrogen in the vessel at or below its saturation temperature. Hydrogen boil-off, and the necessity to provide continuous venting of vaporized hydrogen are minimized or avoided. In a preferred embodiment, the hydrogen storage vessel has a toroidal shape, and the pulse tube refrigerator is a two stage pulse tube refrigerator and extends within a central void space defined at the geometric center of the toroidal storage vessel. Also in a preferred embodiment, the cooling system includes first and second thermal jackets, each having a substantially toroidal shape and enclosing the storage vessel, wherein each of the thermal jackets is thermally coupled to one of the first or second stages of the pulse tube refrigerator in order to cool the vessel and to abate ambient heat leak thereto. The hydrogen storage and delivery system is particularly suitable for use in vehicles, such as passenger automobiles.
Abstract:
A tank heater control that will control a heater used for heating pressurised tanks over a broad range of temperatures. The system uses a sensor for providing a signal to a processor, in which the signal is indicative of flow of gas from the tank. The processor energizes the heater when gas flows from the tank. In various embodiments, the sensor may be a flow sensor on an outlet from the tank, temperature sensors that detect a difference in temperature of the tank from ambient temperature, or a pressure sensor on an outlet from the tank.
Abstract:
Compressed gas canister (1′) intended to supply gas to a fastening appliance (2) that runs on compressed gas, includes a protective edge (12) forming a bowl inside which an ejection valve (16) having a bearing and displacement surface (26) is mounted so that it can move in translation between a position of rest and a gas-ejection position. The ejection valve (16) is mounted, inside a seal (3′), set back from the edge (15) of the bowl. The bearing surface (26) of the valve (16) does not protrude beyond the edge (15) of the bowl in the position of rest and is set back from the surface (30) facing towards the outside of the seal (3′, 23) in the gas-ejection position.
Abstract:
A device by pressure vessels (2) for sea transport of petroleum fluids, where at least two pressure vessels (2) are connected to and communicate with a manifold (1).
Abstract:
The invention relates to a tap for use in discharging limited volumes of gas, especially for inflating balloons for children, having a flexible sealing element (38) mounted on a manually actuatable control lever (32) and having two sealing surfaces, each of which cooperates with a tap seat (28,30) formed on the body (12) of the tap (10). One of the seats (28) is adapted to be engaged by an inner sealing surface of the sealing element (38) and the other seat (30) surrounding the first seat (28) cooperating with a second external sealing surface provided on a flexible circumferential lip (38″) of the sealing element (38). The flexible lip (38″) is provided with circumferentially spaced radial slots (39) in the outer edge thereof to limit the gas flow during initial opening movement of the tap (10) in a discharge mode of operation.

Abstract:
A method of utilizing a divided pressure vessel in a processing system employing a carbon dioxide based solvent includes transferring a first carbon dioxide based treating solution from a first liquid chamber in a divided pressure vessel having a plurality of liquid chambers to a processing vessel, returning the first treating solution from the processing vessel to the divided pressure vessel, transferring a second carbon dioxide based treating solution having a composition different from the first treating solution from a second liquid chamber in the divided pressure vessel to a processing vessel, and returning the second treating solution from the processing vessel to the divided pressure vessel. A divided pressure vessel may allow multiple solvent baths each having a different chemical composition to be stored and/or processed in a single pressure vessel while maintaining the different chemical compositions of the multiple solvent baths. Thus, such divided pressure vessels may provide the improved operational efficiency of a carbon dioxide based system having multiple solvent baths while decreasing the capital costs that may be associated with such systems.
Abstract:
A mounting structure, for a plurality of high pressure gas vessels (11a, 11b), has a block-shaped vessel mounting member (1) with a high rigidity formed with accommodating portions (5a, 5b, 9a, 9b) for accommodating first neck portions (12a, 12b) formed at one sides of the plural high pressure gas vessels and vessel base-valves (13a, 13b) and formed with a gas flow passage (6) that opens at openings (7a, 7b) of right and left side walls of the vessel mounting member (1) to allow the accommodating portions to communicate with one another. The neck portions (12a, 12b) and the vessel base-valves (13a, 13b) at the one sides of the plural high pressure gas vessels are accommodated in the accommodating portions (5a, 5b, 9a, 9b) of the vessel mounting member 1, and the plural high pressure gas vessels are mounted in the vessel mounting member (1), enabling the gas flow passage 6, formed in the vessel mounting member (1), to serve as a high pressure conduit portion.
