Abstract:
PROBLEM TO BE SOLVED: To provide a generator type power supply with a fuel pack capable of being continuously used even if the fuel pack must be replaced. SOLUTION: In a case 2 of a generator module 1, a generator unit including a fuel battery, and two fuel pack accommodating units 5 are provided. Each of the fuel pack accommodating unit 5 accommodates a fuel pack 21. The generator unit generates electricity by using a fuel supplied from one fuel pack 21, and after the fuel pack 21 becomes empty, the generator unit automatically switches to use a fuel supplied from the other fuel pack 21.

Abstract:
PURPOSE:To easily replace gas in a vessel, by placing a sheet bag in the vessel and inflating the sheet bag with gas thereafter collecting only the sheet bag to the outside of the vessel. CONSTITUTION:Placing a sheet bag 2 from a port 3 in a vessel 1 with unnecessary residual gas 5 and connecting a source 18 of required gas to the sheet bag 2, the inside of the vessel 1 is filled with the sheet bag 2 and required gas 6 by both inflating the sheet bag 2 with the required gas 6 and discharging the unnecessary gas 5 to the outside from a port 4. Then disconnecting the sheet bag 2 from the source 18 of the required gas, the sheet bag 2 is collected from the port 4. And then if the port 4 is enclosed by a blanking material 7, the inside of the vessel 1 is filled with the required gas 6, completing the unnecessary gas 5 to be replaced. When the vessel 1 is formed in a complicated shape or a part is provided in the inside, it is effective to use the plural sheet bags 2.
Abstract:
The invention relates to a cushion (1) for isobarically storing a storage fluid (2) in a storage container (12, 16), comprising a closed and at least partially flexible shell (3), wherein at least one cushion gas (4), which condenses between -200 °C and 200 °C and between 0 bar and 300 bar, is provided in the shell (3) and wherein at least one phase change material (PCM) (5), which is at least partially in the solid phase and which melts between -200 °C and 200 °C and between 0 bar and 300 bar, is provided in the shell (3).
Abstract:
The invention relates to a station (1) and method for filling a tank (7) with a fuel gas. Said station includes at least one fuel gas source store (3) and a gas transfer system (8) having a first upstream end connected to the source store(s) (3) and a second downstream end that is in fluid communication with the tank (7). The gas transfer system (8) includes at least one control valve (9, 10), characterized in that the at least one source store (3) includes a rigid outer wall and a flexible sealing wall (2) that is arranged inside the space defined by the rigid outer wall. The flexible wall (2) defines a storage space for the fuel gas. The first upstream end of the system (8) is connected to the storage space defined by the flexible wall (2). The at least one control valve is also characterized in that the space located between the flexible wall (2) and the outer wall is connected to a system (12, 13) for transferring liquid into the source store (3) in order to fill or extract the liquid in the source store (3) and control the pressure in the store (3) when filling and/or extracting fuel gas within the sealing wall (2).
Abstract:
Bei einem Speicherbehälter (10), insbesondere für ein Setzgerät, umfassend eine äußere Behälterwandung (11) zur Begrenzung eines Gesamtinnenraumes (14) des Speicherbehälters (10), einen innerhalb des Gesamtinnenraumes (14) angeordneten Beutel (7) aus einem flexiblen Folienmaterial, so dass der Gesamtinnenraum (14) von dem Beutel (7) in einen Innenraum (15) zur Befüllung mit Brennstoff (17) innerhalb des Beutels (7) und einen Außenraum (16) zur Befüllung mit Außengas (18) außerhalb des Beutels (7) unterteilt ist, wobei das flexible Folienmaterial des Beutels (7) aus einem ersten und zweiten Folienmaterialteil aufgebaut ist und das erstes und zweite Folienmaterialteil an einem Verbindungsbereich (21) stoffschlüssig miteinander verbunden sind und das flexible erste und zweite Folienmaterialteil je eine Folie (31) aus einem Metall umfasst, eine Entnahmevorrichtung (25), insbesondere ein Ventil (26), zum Ausleiten des Brennstoffes (17) aus dem Innenraum (15), soll eine Permeation von Stoffen zwischen dem von dem Beutel (7) abgetrennten Innenraum (15) und Außenraum (16) im Wesentliche ausgeschlossen und der Speicherbehälter (10) in der Herstellung preiswert sein. Diese Aufgabe wird dadurch gelöst, dass die beiden Folien (31) aus dem Metall des ersten und zweiten Folienmaterialteiles (19, 20) an dem Verbindungsbereich (21) mit einer Metallverbindung (22) miteinander verbunden sind, um eine Permeation von Stoffen (17, 18) aus dem Außenraum (16) in den Innenraum (15) und umgekehrt an dem Verbindungsbereich (21) zu verhindern.
Abstract:
The invention relates to a pressure vessel for receiving at least one fluid medium, and comprising a first shell (1) and a second shell (3) that at least partially encompasses said first shell (1), the first shell (1) having, at least at one of its ends, a collar portion (5) which comprises a securing element (15) that forms an opening (13) for supplying and discharging the medium. The vessel is characterised in that a support element (19), which is in the form of a split ring and surrounds said opening (13), is provided inside the container and has a contact surface (39) adapted to the curved shape of the first shell (1) inner side which is attached to the collar portion (5), said contact surface being able to be pressed onto the first shell (1) using a pressing device (43, 45).
Abstract:
Bag (1) for application in an external container (2) for forming a pressure vessel (2) with two separate compartments (3,4), that is manufactured from an elastic and stretchable material that is such that the bag (1) can stretch from an unstretched state to a stretched state when the bag (1) is filled with a product (9) or when the bag (1) is inflated with air, whereby the stretching of the bag (1) is reversible and whereby the stretch is so substantial that the bag (1) can be used for constructing pressure vessels (2) of diverse dimensions.
Abstract:
A sealing system for an outlet of a plastic-lined cylinder has a plastic liner outlet extending into a bore of a boss. An insert is engageable with the bore, forming a primary seal between the insert and portion of the liner outlet. Further, a tapered compression surface of the insert engages a tapered bore portion of the liner outlet adjacent the primary seal for compressing the liner outlet and closing any annular assembly clearance at the primary seal for obviating opportunity for seal extrusion under pressure. An axial position in the boss and dimensional integrity of the liner outlet is maintained by engaging an annular distal end of the liner outlet in the bore by a stop. The stop can be integral with the boss. Reverse extrusion of the primary seal due to trapped gas and rapid decompression of the cylinder can be defeated by providing a leak path.
