Abstract:
Die Erfindung betrifft einen Wärmespeicher (1) für eine adiabatische Druckluftspeicheranlage zum Zwecke der Energiespeicherung, umfassend einen Druckbehälter (4) und ein im Druckbehälter (4) angeordnetes Wärmespeichermaterial (3), wobei zwischen dem Wärmespeichermaterial (3) und einer Druckbehälterwand (7) zumindest eine thermisch isolierende Schicht (2) angeordnet ist. Erfindungsgemäß ist die zumindest eine thermisch isolierende Schicht (2) aus zumindest einem Isoliermaterial, welches einen Porenanteil von 20 Volumenprozent bis 80 Volumenprozent aufweist und bei Temperaturen von bis zu mindestens 650 °C in Festkörperform vorliegt, ausgebildet oder umfasst dieses Isoliermaterial.
Abstract:
Safe storage of volatile compounds or elements is provided by utilizing storage configurations that take advantage of the diffusibility and release characteristics of cell-based materials, such as foam materials. Such configurations may provide storage of hazardous, liquefied gases in closed-cell foam material. Release of gas/liquid from the foam is restricted by the need for the gas to diffuse through the closed cells. Because rapid release is prevented, storage safety is greatly improved.

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:
The invention relates to an element (7) intended to decrease the risk of explosion when handling fuel inside a container (1). The element is adapted to be positioned inside the container and is arranged to suppress a possible combustion of the fuel inside the container. The invention also relates to a use of such an element inside a container to decrease the risk for explosion when handling fuel.
Abstract:
The invention concerns a tank (10) for a two-phase cold gas propulsion system of a space craft comprising a microporous structure (3) capable of ensuring, in a part of the tank (10) which opposite to an orifice (4) discharging gas outside the tank (10), capillary retention in liquid phase of a two-phase fluid contained in the tank (10). A device for thermal control of the tank (10) comprises at least one heater (2) associated with the part of the tank (10) containing the gas phase, as well as a thermistor (5) in said part, and at least one other thermistor (6) in the part of the tank (6) containing the microporous structure (3) and the liquid phase. The mechanical structure (1) of the tank (10) is mounted on the structure of the space craft through a rigidly mounted interface (7) and a flexibly mounted interface (8). The invention is useful in particular for equipping satellites weighing some tenths to some hundreds of kilograms.
Abstract:
Apparatus controllably breaks hollow spheres stored in an enclosure. A first screen is disposed within the enclosure on a screen support. The screen has holes that are no larger in mesh size than the smallest hollow spheres. The screen support provides support to the first screen and has void areas to allow debris from broken spheres to pass through. An impeller is in contact with the first screen such that movement of the impeller across the first screen breaks the hollow spheres in contact with the first screen.
Abstract:
Large amounts of hazardous goods, especially liquid ones such as fuel, may be carried in safety containers, whether tank semitrailers, oil tankers, containers for hazardous goods or aircraft, and be transported with practically no risk for the environment, by completely filling the inside (10) of the container with glass wool, so that the hazardous materials or other fillings dispersed therein may not escape or be somehow spilled in the environment. The liquid components, for example hydrocarbons, are absorbed and held by a dense, water-proofed latticework (15), so that no oxygen can reach them. They are thus protected against explosions and spillage in the environment. At the same time, a safety container of this type acts as a kind of safety buoy, preventing water from entering the inside (10) of the container, so that the kerosene, gasoline or oil contained therein further increase buoyancy. As a whole, a simplification of the safety container design and a considerable increase in safety may be noted.
