Abstract: Measures for monitoring and manufacturing tanks for cryogenic liquids. The tank is manufactured in a way that signal and power lines from a control unit to sensors of the cryogenic tank are integrated with the tank walls. The conductive track structure so formed has a layer structure that uses the naturally occurring or artificially generated insulating layer on the tank wall material as a substrate on top of which conductive paths are formed that connect the sensors to the control unit.

Abstract: A method for producing a component is disclosed. In a first step, a planar component layer is produced on a base surface from a metal material which is above the melting temperature thereof. In a second step, shear stresses are introduced into the component layer produced in the first step by a friction pin which rotates about a rotation axis and which is pressed with a predetermined force onto an outer surface of the component layer opposite the base surface and which is moved along the entire outer surface of the component layer. Finally, in a third step, the first step is repeated on the outer surface as a base surface.

Abstract: A friction-stir tool including a rotary-drivable tool body, at whose end facing away from the drive is provided a shoulder, from which extends in the direction of that end of the tool body that faces away from the drive, a rotatable rod-shaped projection that has a smaller diameter than the shoulder. The surface of the shoulder that points in the direction of the projection is form-adaptable.

Abstract: The present invention is directed to a profile for a truck floor, particularly for a bridge or troughed floor, that comprises at least one web with a lateral surface facing toward the load, whereby at least a region of the profile adjoining the lateral surface is particle-reinforced, and is also directed to a dumpster floor formed therefrom.
