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 compressed natural gas (CNG) refueling system has banks of cylinders containing CNG, a hydraulic fluid reservoir containing a hydraulic fluid which does not readily mix with CNG, and reversible flow valves. Each cylinder has a fitting installed in an opening at one end. The fitting contains a hydraulic fluid port and a gas port. The other end of each cylinder is closed. Hydraulic fluid is pumped from the reservoir into each cylinder through the hydraulic fluid port. Inside each cylinder, the hydraulic fluid directly contacts the CNG, forcing the CNG out through the gas port. When a sensor detects that the cylinders are substantially drained of CNG, the reversible flow valves will reverse orientation, allowing the hydraulic fluid to flow back into the reservoir.
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:
The present invention is an inflation system utilizing an inflation device and an adaptor therefor. The inflation device includes a cylindrical housing which receives a pressurized cartridge of gas, a head unit, and a nozzle. The head unit of the device includes structure for creating and delivering a metered bolus of gas per each actuation of the device. The device audibly indicates to the user when a single bolus of gas has been successfully delivered to an inflatable bladder. In another aspect of the invention, an elastomeric inflation port which serves as an adaptor for connecting the inflation device of the invention to an inflatable bladder is provided. The inflation port of the invention may also function as a fluid release mechanism to vent fluid from the bladder.
Abstract:
A variable-volume compressed natural gas ("CNG") storage vessel connected to a line supplying pressurized natural gas is described. The vessel connects to a dispensing station having a connection head--a fitting that allows a vehicle tank quickly and easily to be interconnected with and disconnected from the dispensing station. When a vehicle tank is being filled, or alternatively when a storage vessel is being replenished from the gas supply line, a controller responds to the pressure within the storage vessel to vary the volume of that vessel.
Abstract:
In various embodiments, lined underground reservoirs and/or insulated pipeline vessels are utilized for storage of compressed fluid in conjunction with energy storage and recovery systems.

1. Sicherheitsvorrichtung für durch Gasdruck beaufschlagte Behälter. 2. Eine Sicherheitsvorrichtung (1) für durch Gasdruck beaufschlagte Behälter, insbesondere zur Absicherung der Arbeitsraum-Gasseite hydropneumatischer Einrichtungen, wie Hydrospeicher, mit einer Entlastungseinrichtung (2) zum Abbau eines erhöhten Gasdruckes in dem jeweiligen Behälter (3), hervorgerufen durch Hitzeeinwirkung, ist dadurch gekennzeichnet, dass die Entlastungseinrichtung (2) ein unter Einwirkung einer Schub- oder Druckkraft belastetes Bauteil (4) ist, dessen Gestaltsveränderung bei Hitzeeinwirkung auf die Sicherheitsvorrichtung (1) in einem nach außen geschlossenen Raum (5) derart erfolgt, dass eine fluidführende Verbindung (6) von dem Inneren des Behälters (3) nach außen in Richtung der Umgebung ermöglicht ist.
Abstract:
Bekannte Druckzylinder für die statische Hochdrucktechnik weisen eine externe Hochdruckpumpe auf, die über Verbindungselemente mit dem Druckzylinder verbunden werden. Derartige Anordnungen sind jedoch relativ aufwändig und kostenintensiv, außerdem lassen sie sich nur schwer einstellen. Der flüssigkeitsgefüllte Druckzylinder nach der Erfindung weist deshalb eine integrierte Druckerzeugung in Form einer Deckel-Kolben-Kombination (3) auf, die aus einem Deckel (9) und einem damit einstückig verbundenen, im Druckzylinder (1) über ein Dichtungssystems (11) druckdicht und in einer Passung geführten Kolben (10) aufgebaut ist. Über mehrere Schrauben (12) am Umfang des Deckels (9) ist die Deckel-Kolben-Kombination (3) mit dem Druckzylinder (1) unter veränderbarer Druckausübung des Kolbens (10) direkt auf die Flüssigkeitsfüllung im Druckzylinder (1) verschraubbar. Durch diese einfache und kostengünstige Anordnung können durch eine feindosierbare Verstellung des Kolbens (10) in der Flüssigkeit (2) statische Hochdrücke bis in einen Bereich von weit über 1·10 8 Pa dauerhaft aufgebracht werden. Einsetzbar ist der Druckzylinder nach der Erfindung insbesondere in der Messtechnik und beispielsweise zur Untersuchung von druckadaptierten Organismen aus der Tiefsee.
