The invention relates to a prefabricated modular house element module, which is comprised of interconnected wall elements (1), (2) and roof elements (3), (4) with an internal frame and external cover plates attached to it. A set of connecting elements are mounted to the wall elements and roof elements, where a mechanical connection ensures the relative position of a wall element and a roof element, as well as of two roof elements, where the wall elements are connected to the roof elements by a cover that provides protection against precipitation. The invention makes it possible for the prefabricated wall and roof element modules produced with the usual technology to be made suitable with a few auxiliary elements to be partially folded and transported to the place of assembly in a known and usual way, and there they can also be unfolded and positioned in a few movements, as a result of which larger structures can also be built, which structure only needs to be closed at two ends with a separate wall element.

Process and apparatus for producing elementary nanoparticulate mineral components and rare metal oxides therefrom using primary and secondary mineral resources by filling raw material (1,15,16,17) into a mixing tank (7), wherein it is diluted with water to a 20% by weight colloidal solution, then the colloidal solution is fed to a colloid mill (8) and dispersed into particles having an average particle size of up to 10 µm, then transferring it to a wet grinding attritor (9), the nanoparticulate colloidal solution thus obtained is passed under pressure to a classifying unit (10) in which its nanocrystallite content is separated into at least two size fractions, each size fraction being dried in a vacuum drier (11), while a further nanocrystallite fraction containing trace elements is separated by the vacuum drier (11), which is passed to a separator (13,11a) where adsorbed rare metal trace elements are separated.
The subject matter is particularly suitable for the disposal of red mud, the extraction of valuable rare earth elements and other secondary industrial raw materials inherent thereof, the cleansing of industrial filter dust hazardous waste, and the extraction of secondary industrial raw materials inherent thereof. The advantage of the technology is that its relatively low energy demand and initial water supply may enable its profitable operation even in areas of use where similar results were not yet economically achievable.

The present invention relates to a core-shell heat storage microcapsule having a core containing a phase change heat storage material and a coating of amorphous glassy alginate, which coating has at least two layers and at least one layer contains nanoparticles, and the surfaces of the core and the coating are in direct or spaced contact, and the microcapsule core has a solid or internal cavity. The invention also relates to the preparation and use of the microcapsule. The object of the invention is to provide a heat storage microcapsule with which a rapid and uniform, i.e. congruent, crystallization of the heat storage material can be achieved in a simple and safe manner, wherein the coating of the microcapsule effectively prevents the release of the phase change material or components from the microcapsule. The aim is also to produce microcapsules with improved mechanical and thermal properties and reliable long-term stability.
