Abstract:
This invention is directed to pressure vessels in which the strength necessary to withstand the pressure exerted by a contained fluid under intended operating pressures is provided by a dry filamentous over-wrap.
Abstract:
A storage system for compressed natural gas which includes at least one storage vessel for storing CNG and a cooling station wherein the storage vessel is connected to the cooling station so that CNG may be stored in the storage vessel after had been passing through the cooling station and once the stored gas conditions fall out a set range, it is cooled in the cooling station, and returned to the storage vessel, wherein the storage vessel is thermally insulated from the exterior thereof thanks to the composite materials and especially glass-reinforced polymers whose pressure vessels are made.
Abstract:
A fluid may be transferred using a fluid supply assemblage involving a plurality of intermodal containers (10) and a transfer manifold (50). The intermodal containers have a tank (15) for the storage of the fluid, which tanks are connected to a transfer manifold (50). The transfer manifold (50) has a plurality of manifold inlets (55) and a manifold outlet (60). The manifold outlet (60) is in fluid communication with at least two tanks of the plurality of intermodal containers (10) via the transfer manifold (50).
Abstract:
A self-contained breathing apparatus includes an air cylinder pressurized to about 5500 psi, wherein the air cylinder is compatible with infrastructure used in conjunction with the air cylinder. The self-contained breathing apparatus also includes a first regulator valve for reducing air pressure from the air cylinder to a predetermined level. A second regulator valve is also provided for reducing the air pressure from the predetermined level to a level suitable for use by an operator, wherein air is supplied from the second regulator valve to the operator via a mask. The self-contained breathing apparatus further includes a frame for supporting the air cylinder on the back of the operator. Other embodiments are described and claimed.
Abstract:
Ein Treibstofftank für die gleichzeitige Lagerung von Flüssigkeiten, die durch ein Druckgas aus dem Tank ausgetrieben werden, und der insbesondere für einen Einsatz in Raumfahrzeugen geeignet ist, ist als Membran-Tank aufgebaut, wobei die Membran (3) aus einem Polymermaterial besteht. Die Membran ist mittels eines Federringes (2) in einer inneren Ausnehmung (4) der Außenwand (1) des Tanks gehaltert, wobei der Querschnitt des Federringes in etwa die Form eines C aufweist.
Abstract:
A gas accumulator (10) with an inner gas accumulator bag (29) which forms a gas accumulator space (12) which can be filled with gas, and with an outer membrane (1) which surrounds the gas accumulator bag (29) in some regions, wherein the gas accumulator bag (29) and the outer membrane (1) are fixed in relation to a base surface (4), wherein the outer side of the gas accumulator bag (29) has at least one tab (20, 20', 20'', 20''', 20'''', 20''''') which is at least partially clamped together with an edge region of the outer membrane (1), and wherein the combined clamping is fixed in relation to the base surface (4)
Abstract:
The present invention discloses apparatuses, systems, and methods for controlling liquid impact pressure in liquid impact systems. The liquid impact systems include at least one gas and a liquid, the gas having a density ( PG ) and a polytropic index (κ) and the liquid having a density ( PL ). The methods include the step of calculating a liquid impact load of the liquid on the object by determining a parameter Ψ for the system, wherein Ψ is defined as ( PG/PL )(κ-1)/κ. The systems are also configured to utilize the parameter Ψ. The parameter Ψ may be adjusted to increase or reduce the liquid impact load on the system. Automatic, computer-implemented systems and methods may be used or implemented. These methods and systems may be useful in applications such as LNG shipping and loading/off-loading, fuel tank operation, manufacturing processes, vehicles dynamics, and combustion processes, among others.
Abstract:
This invention relates to a hydrocarbon transfer arrangement for transfer of fluids between an offshore unit (1) and a carrier (2) which are placed in an offloading configuration, comprising of at least one transfer hose (3) and a gas return hose (4), the end of the at least one transfer hose is connected to a floating multi-function unit (6) allowing for the transport of the transfer hose between the process vessel and the carrier, wherein the floating multifunction unit is lifted out of the water and can be hold in a fixed position above water-level and is provided with connection means (7) for making a fluid connection between the transfer hose end and the midship manifold of the carrier and with emergency disconnect means (13) for the at least one transfer hose, placed at a distance from the connection means.
