Abstract: A heating appliance for railway vehicles has at least one heating unit, forming a load-bearing sandwich structure together with edge profiles and a core layer. According to the invention, a plurality of heating units and sandwich structures are provided, each forming modular construction units, and the construction units can be positioned and fixed relative to one another in the railway vehicle by means of connecting elements.

Abstract: Multi-layer moulding having a high structural load-carrying capacity with two opposing broad faces and a laterally peripheral end face, containing, in layers, broad face on broad face, layered wood veneers and, lying between the wood veneers, adhesives. The wood veneers are layered in such a way that the grain of at least one of the wood veneers deviates from the grain of one or the other wood veneers by 45° to 90° and in that the grain of the wood veneers deviates by 22.5 to 67.5° with respect to a surface normal to an end face of the moulding.

Abstract: Shaped articles made of balsa veneers, balsa chips, balsa strands or balsa strips, which are oriented in the same direction according to their grain direction, and the grain direction of the individual chips deviates by 0° to 30° from the direction of the axis of the grain. The spaces of the adjacent balsa veneers, chips, strands or strips are filled with a, for example foamed, adhesive, the density of which may be the same as or close to the density of the surrounding balsa wood.

Abstract: The invention relates to a lighting device, comprising a multi-layer carrier plate with a large number of through-openings, in each of which an LED is accommodated. According to the invention, it is provided that the through-holes, accommodating the LEDs have a circular cross-sectional face. Furthermore, the invention relates to the use of a carrier plate of this type.

Abstract: Planar structural element, as a portion of a foam block, the foam block being made of a foamed plastics material, containing a plurality of stacked foam bodies and/or foam bodies made of body segments, which are arranged next to one another in a plane and connected to one another to form foam bodies and which have flat weld seams at their abutting faces, and the foam bodies being welded to one another at their abutting faces with the formation of flat weld seams to form the foam block. The weld seams between the foam bodies are interrupted by recesses at a spacing from one another. The planar structural element is preferably used as the core or core layer in sandwich composites, for example in rotor vanes of wind power plants.
