Provided is a method for mineralizing wood, wooden material and other cellulosic material comprising: i) a first impregnation step, comprising a fist impregnation of wood, wooden material or other cellulosic material with an aqueous solution of potassium methyl siliconate or potassium oxalate, ii) a first drying step, comprising drying of the wood, wooden material or other cellulosic material, iii) a second impregnation step, comprising a second impregnation of wood, wooden material or other cellulosic material with an aqueous solution of calcium chloride or C02 (gaseous or fluidic), and iv) a second drying step, comprising drying of the wood, wooden material or other cellulosic material. Due to the novel mineralization method, the water insoluble products of the impregnation steps penetrate the material deeply and are generated in situ within the cells themselves, in the cell walls and pits and between the xylem cells ( primarily fibres and sklereids). The mineralized products are protected against fungi, improved in their biological resistance, moisture and weather resistance and exhibit a reduced flammability. The products are non-toxic and environmentally safe.

The invention relates to an insulating glass (10) for a window, comprising at least two glass panes (11, 12) which are arranged at a distance from and parallel to one another and enclose a thermally insulating gap (13), wherein the glass panes (11, 12) are kept apart by means of peripherally extending spacers (17). A greatly improved mechanical stability of the insulating glass is achieved in that the glass panes (11, 12) are each fixedly connected to a common profile (14) which extends peripherally on the outside and, together with the profile (14), forms an intrinsically mechanical stable composite panel.

The invention relates to a device for centering interchangeable circular saw blades (1) and similar tools on the shaft of machine tools or grinding machines, wherein the hub (3) of the saw blade (1) or of a similar tool comprises penetrations (4) so that parts of the hub (3) press on the shaft-hub fit in a spring-loaded manner. The hub (3) is thus undersized in the unjoined state. In the joined state, a self-centering press fit is present. Conical embodiments of the tool hub (3) can facilitate joining and producing the spring-loaded tension.
