Abstract:
A flexible pressure vessel is constructed from at least one pair of upper and mating lower dome shaped cell portions. The dome portions are molded from sheets of resilient material and joined together by radio frequency welding or high-strength adhesives. Upper and lower passageway portions extend outwardly from each cell portion to the surrounding sheet material. When the cell portions are joined the passageway portions are joined to form a passageway for connection to a valve or another cell. Upper and lower rings surround the upper and lower cell portions to provide reinforcement for the cells. First and second blankets of heavy-duty fiber reinforced material are attached over the upper and lower cell portions and stitched in place with heavy-duty stitching extending through the resilient material surrounding the cell portions. Cell shaped sponges impregnated with absorbent materials are encased in liquid and gas impermeable plastic tubing and inserted into the cells prior to joining of the cell portions. Heat-reflecting plastic film or metal foil is inserted between blankets and the cell portions. The heavy duty stitching is high-pressure loop and lock braiding. The passageway has a cross-section of between 0.050 and 0.100 inches. An apparatus and method are described for constructing the flexible pressure vessel.
Abstract:
An electrochemically active hydrogen diffusion barrier which comprises an anode layer, a cathode layer, and an intermediate electrolyte layer, which is conductive to protons and substantially impermeable to hydrogen. A catalytic metal present in or adjacent to the anode layer catalyzes an electrochemical reaction that converts any hydrogen that diffuses through the electrolyte layer to protons and electrons. The protons and electrons are transported to the cathode layer and reacted to form hydrogen. The hydrogen diffusion barrier is applied to a polymeric substrate used in a storage tank to store hydrogen under high pressure. A storage tank equipped with the electrochemically active hydrogen diffusion barrier, a method of fabricating the storage tank, and a method of preventing hydrogen from diffusing out of a storage tank are also disclosed.
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 KEVLAR®. 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 utility belt includes a gas storage vessel for providing a portable and ambulatory supply of oxygen for the person wearing the belt or a person being attended to by the person wearing the belt. In particular, the utility belt provides a portable supply of pressurized gas while it is suspended from the body of a user, with a plurality of item holders, such as implement holsters and utility pouches, suspended from the utility belt. The supply of pressurized gas is provided by a gas storage vessel carried on the utility belt. The gas storage vessel is formed from a plurality of polymeric hollow chamber having either an ellipsoidal or spherical shape and interconnected by a plurality of relatively narrow conduit sections disposed between consecutive ones of the chambers. The gas storage vessel includes a reinforcing filament wrapped around the interconnected chambers and interconnecting conduit sections to limit radial expansion of the chambers and conduit sections when filled with a fluid under pressure. The container system further includes an outlet valve/regulator attached to the gas storage vessel for controlling fluid flow into and out of the gas storage vessel and a gas delivery system for delivering gas from the gas storage vessel to a user in a breathable manner.
Abstract:
A storage tank, especially for liquefied gases, is separated into cells by numerous partitions of a material having low heat conductivity. The maximum diameter of the cells in a plane that is perpendicular to the partitions is less than 50 mm.
Abstract:
The invention relates to a small utility air storage tank that includes a pressure gage and an air flow regulator. The storage tank may be used alone or in conjunction with a second storage for storing and supplying a larger amount of air for use with an airbrush or air blower. The storage tank and second storage tank may be filled with air from an air source. One of the storage tanks may be filled by discharging gas cartridges into the storage tank. An auxiliary tank may be attached to the storage tank for use in sand blasting or to create a vacuum.
