Abstract:
A pressure vessel is provided including an inner tank formed from a tank liner surrounded by a wound layer of composite filaments. A protective jacket is disposed on the inner tank that facilitates stacking and portability of the pressure vessel and helps to define an air passage for convective heat transfer between the hybrid tank and the environment.
Abstract:
Apparatus and method for dispensing a gas using a gas source coupled in selective flow relationship with a gas manifold. The gas manifold includes flow circuitry for discharging gas to a gas-using zone, and the gas source includes a pressure-regulated gas source vessel containing the gas at superatmospheric pressure. The pressure-regulated gas source vessel can be arranged with a pressure regulator at or within the vessel and a flow control valve coupled in flow relationship to the vessel, so that gas dispensed from the vessel flows through the regulator prior to flow through the flow control valve, and into the gas manifold. The apparatus and method permit an enhancement of the safety of storage and dispensing of toxic or otherwise hazardous gases used in semiconductor processes.
Abstract:
A gas container and method of maintaining gas in a container and assembling a gas container are provided. The gas container includes at least a first section and a second section with the first and second sections being substantially hollow and movable relative to each other and a liquid seal for sealing gas within the container. The liquid seal is disposed between the first section and the second section, wherein a first anti-corrosion coating is provided so as to float on the surface of the liquid in the liquid seals, such that in use, the first anti-corrosion coating is caused to be applied to at least a portion of the second section during motion of the second section relative to the first section.
Abstract:
A deep ocean gas storage system for storing compressed gas, the system comprising an inflexible thin walled storage vessel anchored to the sea floor having an axis located in water substantially perpendicular to and on a sea floor below sea level, a gas intake for admitting and discharging compressed natural gas to and from the vessel; a water port for admitting and discharging water to the vessel using hydrostatic pressure to discharge compressed gas from the vessel at a substantially constant discharge pressure as the volume of the gas in the storage vessel decreases when water content of the vessel increases; a conduit fluidly connected with the water port oriented substantially parallel to the axis having a discharge opening above the level of sea water in the vessel; and a valve disposed at the gas intake to the vessel for controlling compressed gas admission and discharge.
Abstract:
The invention relates to a compressed gas container (10′) comprising a block flange (14) that is provided on an upper opening in its wall (12), a flange cover (15) that is equipped with two extraction valves (22) being screwed onto said flange. The block flange (14) is extended radially beyond the region covered by the flange cover (15) by a solid annular flange (40), whose outer periphery is welded to the wall (12) of the container (10′) and whose inner section lying adjacent to the region covered by the flange cover comprises a peripheral groove (44) in an upper front face (42), for holding the sealing rib (46) of an emergency cap. If required, said cap can be screwed onto the annular flange (40) if a leak occurs in the flange region of the container (10′). Compared to a conventional compressed gas container, the inventive container (10′) is simple to produce, as the latter merely requires a larger flange region in order to provide it with the peripheral groove (44) and thus the screw construction for the emergency cap (50).
Abstract:
A dry cryogenic shipping container having a removable absorbent assembly is provided. The dry cryogenic shipping container is structured to be a Dewar's flask having a first, outer shell assembly, and second, inner shell assembly disposed within and spaced from the first, outer shell assembly, and a cap. Within the shipping container is an absorbent assembly having a body with a central cavity. The absorbent assembly body is formed by a plurality of removable absorbent assembly elements. That is the absorbent assembly elements are sized to pass through the passage into the space within the shipping container. As such, after use, the absorbent assembly body elements may be removed and the remaining components may be sterilized. After sterilization, new absorbent assembly body elements are inserted into the inner space and the dry cryogenic shipping container is used again.
Abstract:
Vessel comprising a number of composite storage tanks for transport of compressed natural gas (CNG) or a combination of gas and liquid, which tanks have an elongated, cylindrical intermediate section and a lower end and an upper end, the tanks being arranged side-by-side vertically standing in the vessel, distinguished in that the hull, the bulkheads and the deck of the vessel form a closed space enveloping all tanks except from the upper end of each tank or selected tanks, for which tanks the upper end extends sealingly out of the closed space, all feed-throughs in the tanks with couplings for loading and unloading are outside of the closed space, at the upper end of the tanks, and the tanks are supported such that each tank can expand or contract freely within the operating range of the tanks with respect to pressure and temperature.
Abstract:
A portable propane tank carrier system is provided which includes a tank carrier, stabilizer ring, and tank neck cover. The tank carrier includes a rectangular main tank cover panel, and upper and lower radial sidewall panel. The tank carrier closely conforms to the shape of a portable propane tank while providing an upper opening adapted to receive a neck portion of the tank and a lower opening adapted to receive a tank base ring portion of the tank. The stabilizer rings may be attached to the bottom of the tank carrier to prevent the tank from tipping over.

Abstract:
A gas ejection device includes a bottle (5) having an opening part (13) closed by a lid (14), a needle (6) intruded into a pierced hole (14a) formed in the lid (14) for stopping up the lid. The gas ejection device also includes a holder (7) holding the needle (6) at its one end in a facing relation to the lid (14) of the bottle (5) and movable towards and away from the lid (14). The gas ejection device also includes a biasing member (8) for biasing the holder (7) towards the lid (14) of the bottle (5), and an actuating member (9) for actuating the holder (7) in a direction away from the lid (14) to extract the needle (6) from the pierced hole (14) to open the bottle (5). The gas ejection device also includes a housing (10) for accommodating the bottle (5) and the bolder (7). The bottle has been charged with a compressed gas in advance. The housing includes a gas duct (11) for forwarding the compressed gas, ejected via the pierced hole (14a) in the lid (14), to outside.
