Abstract:
A pressurized gas supply system includes a pressurized container which expands and contracts. The container includes a one-piece liner molded from a polymer which is reinforced by a high tensile fiber such as KEVLARnull. A valve is molded into the liner, and a regulator is connected to the valve. A hose, having a conserver positioned therealong, extends between the regulator and a fitting allowing a user to inhale gas from the container. The container is carried in a carrying bag, which can be in the form of a carrying case, a purse, or a back-pack.
Abstract:
A nested tank construction for pressurized materials comprises first and second cylindrical tanks connected together so that they are axially aligned. The first tank comprises a dome end which is inverted so that it extends inwardly into the first tank and is under compression loading when exposed to pressure within the first tank. The second tank comprises a dome end which extends outwardly from the second tank and is under tension loading when exposed to pressure within the second tank. The first and second tank dome ends have a matching geometry so that the second tank dome end is nested into the first tank dome end. The first tank dome end is a honeycomb sandwich structure comprising an aluminum membrane, a honeycomb core adhered to the concave face of the aluminum membrane, and a fiber composite face sheet adhered to the concave face of the honeycomb core. The honeycomb sandwich structure is co-cured under heat and pressure. A gap is provided between the face sheet of the composite sandwich structure and the second tank dome end. The tank construction is particularly useful for gaseous or liquid materials which are hypergolic when mixed, or which are maintained at cryogenic temperatures.
Abstract:
A leak containment storage facility includes a containment vessel with an inner tank surrounded by an outer tank. Upon detection of a leak in the inner tank, the pressure within the outer tank can be increased, usually by flooding the tank, to contain the leak. This facility has special application in a deep basing environment in which a personnel area is powered by hydrogen/chlorine fuel cells. The chlorine is stored as a liquid in the inner tank. Stored water in a reservoir floods the outer tank to apply a pressure on chlorine that leaks from the inner tank and keeps the chlorine from evaporating. Generally the pressure is achieved by the hydrostatic head alone and pumps or compressors are not use.
Abstract:
In making a pressure vessel, spaced electrically conducting plates are separated by a pattern of electrically conducting tensile members which are held in that pattern by separable electrically conducting casing halves made of material which will not spot weld to the plates, the plates are forcibly engaged against the opposite ends of the tensile members and opposite ends of the casing halves while welding current is passed through and between the plates, and then the casing halves are removed whereafter marginal edges of the plates are joined by welding.
Abstract:
Provided is an X-beam structure including: a plurality of beams extending in X-axis, Y-axis, and Z-axis directions and formed in a lattice pattern and a plurality of cross intersections at which an X-axis beam, a Y-axis beam, and a Z-axis beam meet one another, wherein in the X-beam structure in which a cross section of each beam has the geometry of a right-angled X, and the beam intersections are formed with one continuous beam and the two other joining beams are attached and welded onto the continuous beam.
Abstract:
An orientation independent delivery device (100). The delivery device (100) includes a gas chamber, a delivery chamber, a gas cell (110), and a delivery aperture (112). The gas chamber includes a gas-side rigid portion (102) and a gas-side flexible barrier (104). The gas-side flexible barrier (104) is sealed to the gas-side rigid portion (102). The delivery chamber includes a delivery-side rigid portion (106) and a delivery-side flexible barrier (108). The delivery-side flexible barrier (108) is sealed to the delivery-side rigid portion (106) and is oriented adjacent to the gas-side flexible barrier (104). The gas cell (110) is coupled to the gas-side rigid portion (102) of the gas chamber. The gas cell (110) increases a gas pressure within the gas chamber to expand the gas-side flexible barrier (104). Expansion of the gas-side flexible barrier (104) applies a compressive force to the delivery-side flexible barrier (108) allowing a delivery material to escape from the delivery chamber.
Abstract:
A support assembly mounted on the roof of a tank, comprising a support block (1), a base plate (4) between the support block (1) and the tank, and guiding brackets or rails (2) joined to a structure above the tank characterized in that each of the brackets or rails (2) comprise a face turned towards a cooperating face of the support block, the face of the bracket or rail and the cooperating face of the support block (1) are inclined at an angle, said angle depending on the width and height of the support (1).
