Abstract:
A safety device for containers pressurized with gas safeguards the gas side of the working chamber of hydraulic accumulators. A relief apparatus (2) reduces an elevated gas pressure in the container (3) caused by heat. The relief apparatus (2) is a component loaded under the influence of a shear force or compressive force. The shape change of the component under the influence of heat on the safety device (1) in a space (5) closed to the outside occurs such that a fluid-conducting connection (6) from the inside of the container (3) to the outside in the direction of the surroundings is enabled.
Abstract:
An apparatus for compressing a gas and its uses are disclosed. The apparatus comprises a fixed-volume container having a hollow and a moveable element subdividing said hollow into a first variable-volume portion and a second variable-volume portion, the second variable-volume portion having an opening for introducing therein a hydraulic and/or pneumatic fluid under pressure, for causing an increase in the volume of said second variable-portion by moving said moveable element, thereby, consequently, decreasing the volume of the first variable-volume portion and compressing a gas contained therein.
Abstract:
Described herein is a portable storage device that stores a hydrogen fuel source. The storage device includes a bladder that contains the hydrogen fuel source and conforms to the volume of the hydrogen fuel source. A housing provides mechanical protection for the bladder. The storage device also includes a connector that interfaces with a mating connector to permit transfer of the fuel source between the bladder and a device that includes the mating connector. The device may be a portable electronics device such as a laptop computer. Refillable hydrogen fuel source storage devices and systems are also described. Hot swappable fuel storage systems described herein allow a portable hydrogen fuel source storage device to be removed from a fuel processor or electronics device it provides the hydrogen fuel source to, without shutting down the receiving device or without compromising hydrogen fuel source provision.
Abstract:
A vacuum insulated storage vessel holds a quantity of LNG for delivery to a pressure building tank. The pressure building tank maintains a natural gas head over the LNG. The pressure in the pressure building tank is lowered using liquid nitrogen (LN.sub.2) to condense the natural gas head and is raised by vaporizing the LNG. A valve system connects the supply of LNG in the pressure building tank to the fuel tank of the vehicle being supplied to allow either LNG or natural gas to be delivered to the vehicle tank and allows natural gas in the tank to be vented back to the fueling station. The fueling station of the invention includes suitable controls for controlling the pressure and temperature of the LNG delivered to the vehicle, the pressure and temperature in the fueling station itself and the pressure and temperature in the vehicle fuel tank.

Abstract:
A dual gas pressure vessel assembly comprising a pressure vessel shell, a piston dividing the interior of the shell into a first chamber and a second chamber, an exhaust passage leading from a portion of said first chamber spaced from the piston, a stop limiting movement of the piston towards the exhaust passage, and a burster disc in the piston. The piston carries frangible coupling means rigidly coupling the piston to the shell. In use the two chambers are respectively filled with the two gases required. When the exhaust passage is opened the first gas will be discharged from the first chamber, the piston will move against the stop and, when substantially all the first gas has been discharged, the burster disc will fracture, connecting the second chamber to the exhaust passage.

Abstract:
Eine Sicherheitseinrichtung für durch Gasdruck belastete Behälter, insbesondere die Gasseite (13) hydropneumatischer Einrichtungen wie Hydrospeicher (1), ist dadurch gekennzeichnet, dass sie eine am Druckraum des Behälters anbringbare Anschlußeinrichtung (19) zur Bildung eines Durchganges (25) zwischen Gasseite (13) des Behälters und der Außenseite aufweist und dass ein den Durchgang (25) normalerweise sperrendes Mittel (27) vorhanden ist, das unter Temperatureinfluß in einen Zustand überführbar ist, der die Freigabe eines Strömungsweges durch den Durchgang (25) ermöglicht.
Abstract:
A container for transport and storage of oil/gas specimens etc. comprises a container body (1) having end pieces (3, 4) and a movable piston (6) arranged internally. At each end of the container threaded bores (26) or the like are arranged for coupling hoses or the like for the supply of counter-pressure fluid and oil/gas respectively, together with a valve (35) arranged connected to each of the hose couplings. In the container (1) a bar (2) is concentrically arranged to which the end pieces (3, 4) are fastened. The piston (6) and possibly a mixing ring (6) are slidably arranged on the bar.
