摘要:
The invention is directed to a method for calculating the remaining usage time of a gas cylinder equipped with a pressure reducer, the method comprising the following steps: (a) measuring the pressure of the gas in the cylinder; (b) calculating the variation of pressure of the gas in the cylinder over time while gas is outputted; (c) calculating a remaining usage time Tr based on the measured pressure in the cylinder and the calculated variation of pressure. Step (c) takes into account characteristics of the pressure reducer relative to variations of its nominal flow rate along the decrease of its inlet pressure while emptying the cylinder.

The invention relates to a tank container (100; 100′) for the transport and storage of cryogenic liquefied gas, comprising a framework (120) and a cylindrical vessel (110) connected to the framework (120), wherein the vessel (110) is covered by a superinsulation arrangement (130) based on an aerogel composition, and the vessel (110) is connected to the framework (120) by a clamping device (30) which is adapted to allow for a relative movement between the framework (120) and the vessel (110) due to thermal expansion or contraction of the vessel (110).
摘要:
The invention concerns an assembly (1, 2) for packaging, storing and dispensing gas comprising a protective packaging (1) comprising a bottom (3), a cover (4) and a series of sidewalls (5a-5d) together defining an inner chamber (6), said sidewalls (5a-5d) being located between the bottom (3) and the cover (4), and a gas container (2) provided with a valve block (7) positioned inside the inner chamber (6) of the protective packaging (1), the whole of the gas container (2) and the valve block (7) being covered and protected by the protective packaging (1). A separating wall (15) is arranged inside the inner compartment (6), between the gas container (2) and the cover (4), said separation wall (15) dividing the inner chamber (6) into a lower sub-chamber (6b) containing the gas container (2), and an upper sub-chamber (6a) lying over the lower sub-chamber (6a). Use of the assembly of the invention for packaging and dispensing oxygen, in particular medical oxygen.

An LNG fueling station according to the present invention includes: an installation part on which an LNG tank container is installed, and a supply part for supplying liquefied natural gas from the LNG tank container installed on the installation part to an object for supply, wherein the LNG tank container can be transported and installed while storing the liquefied natural gas, and the LNG tank container is transported to the installation part and then installed on the installation part.
摘要:
Various adaptor configurations are provided that allow newly mandated replacement oxygen modules to replace oxygen generators in the same containers that are currently used in aircraft lavatories. The replacement modules and oxygen generators differ in terms of overall interface dimension, geometries and weights. The adaptors enable replacement modules to be mounted without, or with only minimal, modification of the oxygen containers.
摘要:
An apparatus for restraining an object in a vehicle may have an elongated frame, a clamp member mounted to the frame at or near one end thereof, and an elongated base member movably mounted to the frame between the clamp member and an opposite end of the frame. The base member may include a curved portion having a support surface defining a curvature and a linear portion between the curved portion and the clamp member. The base member may be movable relative to the frame to an object transition position in which a free end of the linear portion extends outwardly away from the frame and the curved portion retracts upwardly toward the clamp member along a path defined by the curvature to allow the object to be received between, and removed from between, the clamp member and the support surface of the base member.
