Abstract:
A sealing mechanism for a fluid-containing member of a pressure-storing device includes nozzle members, a fluid intake unit, and a control unit. Each nozzle member is coupled to a respective fluid inlet of the fluid-containing member, and includes a hollow nozzle body and a valve unit operable so as to move from a blocking position for blocking fluid flow through the respective fluid inlet to an unblocking position for permitting fluid flow through the respective fluid inlet. The fluid intake unit is coupled to the fluid-containing member such that the nozzle members are disposed between the fluid intake unit and the fluid inlets. The control unit is operable so as to drive movement of the valve units of the nozzle members from the blocking position to the unblocking position.
Abstract:
The present invention relates to a multi-cell tank (2) for pressurised gas formed by a group of tubes (2a) immersed in a fibrous resin body (4) and reinforced by means of external texture (7), closed with two covers that feature a intercommunicating series of domes on the internal side, which exactly match the opening of the tubes of the group.
Abstract:
The invention provides apparatus for inflating an inflatable safety restraint cushion and associated methods for producing an inflation gas for inflating an inflatable safety restraint cushion which rely, at least in part, on Joule-Thomson heating to form an inflation gas.
Abstract:
A hydrogen storage unit which uses hydrogen storage alloys to store hydrogen, and more particularly a heat transfer management/compartmentalization system for use in such system. The hydrogen storage alloy may be divided into compartments, separated by discs, further divided into sub-compartments by a flapper wheel. The discs and flapper wheel provide for optimal heat transfer throughout the system. The compartmentalization of the vessel may prevent compaction of the hydrogen storage alloys, which could lead to excessive strain on the vessel causing damage, deformation, or rupture of the vessel.
Abstract:
A storage container for cryogenic liquids has an outer container and at least one inner container, an insulation space being situated between the outer container and the inner container or containers. The outer container and/or the inner container have devices for strengthening the container walls. The devices for strengthening the container wall of the outer container and/or of the inner container are constructed as at least one web arranged on the container wall of the outer container and/or of the inner container and/or as at least one supporting plate adapted essentially to the cross-section of the inner container.
Abstract:
A pressure vessel for holding a pressurized fluid such as compressed natural gas ("CNG") includes two end cells and zero or more interior cells. The cell geometry ensures that the cells meet one another at tangential circular surfaces, thereby reducing the tendency of adjacent cells to peel apart. A web secured about the cells includes two sheets that are tangent to the cells. Unused volumes between the cells and the web contain wedges of foam or rubber. A valve provides fluid communication between the interior of the pressure vessel and a pressurized fluid line. The filled weight of one pressure vessel does not exceed the filled weight of a conventional gasoline tank that occupies substantially the same space as the pressure vessel. The pressure vessel may be configured with exterior recesses for engaging conventional gasoline tank straps.
Abstract:
The present invention relates to a pressure vessel (1) comprising at least one intermediate part (4) with an end wall (2, 3) connected to each of its ends (1A, 1B), and longitudinal internally reinforcing walls dividing said intermediate part (4) into fluid-accommodating compartments. The intermediate part (4) with enclosed reinforcing walls consists of an extruded profile with reinforcement and an intermediate part casing integrated with one another, and the respective end walls (2, 3) are capable of attachment by fastening means to the end of the respective intermediate part so that forces arising inside the vessel as a result of the internal overpressure against the respective end wall (2, 3) are distributed so that they act axially in the intermediate part (4), both in its outer casing and internal reinforcement.The invention also relates to a method for the manufacture of the pressure vessel in accordance with the invention.
Abstract:
A fluid containment apparatus including a fluid tank, a well wall and a closure system. The tank has a tank shell, which defines at least in part a fluid containment compartment and has a tank shell opening therethrough. The well wall is secured to the tank shell, positioned at the shell opening, recessed into the fluid containment compartment and defines at least in part a recessed well. The well wall has a well wall end and a well wall end opening. The closure system selectively opens and closes the well wall end opening. The closure system includes a well head connected to the well wall generally at the well wall end, a sealing gasket, an elliptical manway cover having a plurality of drilled and tapped blind holes, a separate fastening ring having a plurality of circumferential drilled through-holes and a clamp for clamping the manway cover and the fastening ring together and sandwiching the sealing gasket on the well head. The clamp includes a plurality of bolts boltable through the through-holes and into the blind holes.
Abstract:
The invention relates to tanks for the storage of liquid and has particular application to the land storage of liquefied gas at low temperature at or above atmospheric pressure. Thus, the invention provides a storage tank of the kind in which the walls are formed by a multiplicity of connected, parallel, part-cylindrical lobes presenting outwardly convex arcuate surfaces, which is characterized in that the side and end walls thereof are provided by a single tier of connected lobes, in that said lobes extend in one common direction over the tank, in that the end walls of the tank comprise part-spherical knuckles closing off the ends of the part-cylindrical lobes, and in that a separating plate is provided at each lobe connection to strengthen the tank against internal pressure and to divide it into separate storage compartments.
Abstract:
A cryogenic fuel tank of a cylindrical design having toroidal surface ends, is suspended in aircraft structure through a central front mount member; and the rear tank is supported by rod elements which extend from a mounting ring about the tank, to mount points rearwardly within the interior of the fuselage. The central front mount member has baffles attached thereto, so as to prevent undue sloshing of the liquid within the tank. The front end of the tank suspension absorbs radial and axial loads, but no bending moments; and the aft linkage suspension arrangement takes primarily radical and torsional loads. Also the aft suspension provides for unrestrained axial and radial contraction and expansion of the outer shell of the tank.
