Abstract: The invention relates to a composite board composed of wood material, comprising a middle layer composed of plywood, wherein the middle layer is connected to at least one outer layer composed of fiberboard. In order to provide an economically producible composite board having improved strength properties, an artificial resin-impregnated paper according to the invention is arranged between the middle layer and the outer layer. The invention further relates to a method for producing the composite board composed of wood material.

Abstract: A composite board composed of wood material with a middle layer (4) made of chipboard, wherein the middle layer is connected to at least one outer layer (2, 6) composed of fiberboard, wherein an artificial-resin-impregnated paper (3, 5 ) is arranged between the middle layer and the outer layer.

Abstract: A plate heat exchanger with a plurality of separating walls stacked one above the other, which alternatingly define a first and second flow space for a first and second medium, includes at least one turbulence generator being positioned in at least one flow space, which comprises a plate with a number of parallel-running band-like rows of alternating elevations and depressions mutually connected by bridges, where the elevations and depressions of each row are shifted with respect to each immediately adjacent row, and where each row is provided with at least one transition area for the medium to pass to the immediately adjacent row, such that the depressions of each row are flow-connected with the immediately adjacent elevations of at least one immediately adjacent row.

Abstract: For assigning a tool to a workpiece conveyed on an assembly line, at least one transmitter is arranged in the area of an assembly line, and a receiver is arranged on the tool. An analyzing unit determines the distance of the tool from each transmitter, based on the transit times of at least one received signal, and an indicating device emits positions information regarding workpieces on the assembly line. An assignment unit assigns a tool or a tool position to a workpiece, based on at least one distance of the tool from the transmitter, and on the workpiece positions. The arrangement of the transmitters and receivers can also be interchanged.
