    Abstract: La invención se refiere a un dispositivo para almacenar calor, que comprende un medio de almacenamiento de calor que absorbe calor a fin de almacenar calor y libera calor a fin de usar el calor almacenado, y un contenedor para sostener el medio de almacenamiento de calor, el contenedor estando cerrado por una cubierta hermética a gas, y el dispositivo que comprende medio de compensación de volumen a fin de compensar por un aumento de volumen del medio de almacenamiento de calor (3) debido a un aumento de temperatura y una disminución de volumen debido a una reducción de temperatura. La invención se refiere además a un método para almacenar calor, en donde se transfiere calor a un medio de almacenamiento de calor a fin de almacenar calor o descargar calor desde el medio de almacenamiento de calor al portador de calor a fin de usar el calor, el medio dé almacenamiento de calor siendo sostenido en un contenedor que se cierra por una cubierta hermética a gas, en donde una expansión de volumen del medio de almacenamiento de calor (3) se compensa por un aumento de volumen del contenedor (1) o por medio de almacenamiento de calor (3) fluyendo fuera del contenedor (1) en un contendor de regulador (21; 63, 65), y una disminución de volumen del medio de almacenamiento de calor (3) se compensa por una disminución de volumen del contenedor (1) o por medio de almacenamiento de calor (3) fluyendo fuera del contenedor de regulador (21; 63, 65) en el contenedor (1).

    Abstract: The invention relates to a device for storing heat, comprising a heat storage medium, which for storing heat takes up heat and for using the stored heat gives off heat, and a tank for receiving the heat storage medium, wherein the tank is closed by a gas-tight covering, and means for volume equalization are comprised, in order to equalize an increase in volume of the heat storage medium (3) as a result of an increase in temperature and a decrease in volume as a result of a decrease in temperature. The invention also relates to a method for storing heat, in which, for storing heat, heat is transferred to a heat storage medium or, for using heat, heat is removed from the heat storage medium and passed to the heat transfer medium, wherein the heat storage medium is held in a tank, which is closed by a gas-tight covering, wherein an expansion of the volume of the heat storage medium (3) is equalized by an increase in the volume of the tank (1), or by heat storage medium (3) flowing out of the tank (1) into a buffer tank (21; 63, 65), and a decrease in the volume of the heat storage medium (3) is equalized by a reduction in the volume of the tank (1) or by heat storage medium (3) flowing out of the buffer tank (21; 63, 65) into the tank (1).

    Abstract: A solution system for biopolymers in the form of carbohydrates based on a molten ionic liquid, additives optionally being contained in the solution system, is described. This solution system contains a protic solvent or a mixture of several protic solvents, and in the case where the protic solvent is solely water, this is present in the solution system in an amount of more than about 5 wt. %. Carbohydrates can be incorporated into the solution system, in particular in the form of starch, cellulose and derivatives thereof, and it can then be used for regeneration of the carbohydrates contained therein. A particularly advantageous process for the preparation of the solution system containing the carbohydrates and for the preparation of regenerated carbohydrates, in particular in the form of regenerated cellulose fibers, is moreover described. The invention accordingly also provides such spun fibers as are distinguished in that they are non-fibrillating. The invention offers in particular economic advantages over the systems of the prior art.
