Abstract:
The present disclosure is related to methods and apparatus that provide safe storage of volatile compounds or elements, utilizing storage configurations that take advantage of the diffusibility and release characteristics of cell-based materials, such as foam materials.
Abstract:
An ovoid flexible pressure vessel is described. At least one hollow pressure cell, formed of resilient material, a passageway, a valving means, a capillary tube, hoop winding, high-strength braiding material and at least one reinforcing ring are provided. The ovoid flexible pressure vessel has a pressure relief device comprising a reduction in thickness of the hollow pressure cell at a predetermined location whereby, when the hollow pressure cell is subjected to an overpressure condition it will fail at the predetermined location. Further pressure release devices include the following: a reduction in thickness of the cell, an indentation, a projecting member, a weakened section of the passageway, a weakening or an absence of high-strength braiding material of hoop winding at a predetermined location along the passageway, a weakening or spreading of fibers in either of the reinforcing panel or in either flexible blankets.
Abstract:
The invention concerns a process for the manufacture of an explosion protection system for a container (7) for inflammable liquid or gaseous substances, whereby individual sections (6) on the surface of a foil strip (1) that is made of a material with good heat-conducting properties, are permanently bent out of the plane of the untreated foil strip; from the such treated foil strip, at least one three-dimensional filling piece (10) with a large interior surface is manufactured by division and/or deformation and said filling piece is inserted into the container (7), therefore filing at least the major part of the interior space of the container, as well as an explosion protection system of that kind.
Abstract:
The present invention provides a method and a system for handling gaseous fuels using sub-tanks (3) as gas emitting entities within a fuel tank (1). In particular the invention provides a system comprising an exchanger unit (2) for filling filled sub-tanks (3) to, and removing emptied sub-tanks (3) from, the fuel tank (1). Thanks to the invention the filling and removal is fast, efficient and safe.
Abstract:
This invention is directed to a method of decreasing the rate of escape a gas from a breached containment system by introducing into the containment system a plurality of objects that create a tortuous path for the gas to get to the point of breach thereby substantially reducing the degree of damage done by the breach.
Abstract:
Die Erfindung betrifft ein Betriebsgassystem (1a, 1b) für ein Unterwasserfahrzeug, insbesondere für ein U-Boot oder ein unbemanntes Unterwasserfahrzeug, umfassend eine Brennstoffzellenanlage (3) und einen mit der Brennstoffzellenanlage (3) strömungstechnisch verbundenen Betriebsgasbehälter (5). Im Hinblick auf eine einfache und effiziente Speicherung von Boil-Off-Gasen (BO) ist zudem eine Gasaufnahmevorrichtung (7) vorgesehen, die mit dem Betriebsgasbehälter verbunden ist. Die Gasaufnahmevorrichtung (7) enthält ein Sorbtionsmittel (9, 19) zur Aufnahme von Boil-Off-Gas (BO) aus dem Betriebsgasbehälter (5). Somit wird das Boil-Off-Gas (BO), welches im Betriebsbehälter (5) mit dem Betriebsgas (BG) für die Brennstoffzellenanlage entsteht, und welches nicht unmittelbar in der Brennstoffzellenreaktion verbraucht werden kann, aufgesammelt und mit Hilfe des Sorptionsmittels (9, 19) in der Gasaufnahmevorrichtung (7) gespeichert.
Abstract:
The vessel of a heat storage and release apparatus is provided with a shell made of metallic material with an internal cavity for containing a heat storage and release device and for guiding gas-flow, a first opening through the shell for a flow of gas at high temperature and high pressure in and out of the cavity, a second opening through the shell for a flow of gas at low temperature and high pressure in and out of the cavity, and a lining of thermally insulating material covering only partially the internal surface of the cavity; the lining is located at least in the region where the first opening is located, i.e., where the temperature is higher; in this way, the temperature of the shell can be controlled. Such heat storage and release apparatus can be provided in an energy production plant as a component of an energy storage and release system to be used for compensating differences between energy produced and energy demanded.
Abstract:
The invention comprehends a tank for storing fluid under pressure and a method for manufacturing the tank. The tank has an inner core of an open- celled foam that is characterized by open voids that are at least partially interconnected by passages and are surrounded by a fibrous or ligament structure/network (collectively, 'ligaments'). Attached to the inner core is an outer skin.
