Abstract: A method for producing a probe of a thermal flowmeter for measuring mass flow of a medium in a measuring tube, wherein a probe core is provided arranged loosely in a probe sleeve having a longitudinal axis, wherein the probe sleeve is deformed relative to the longitudinal axis completely radially in the direction of the probe core by means of high energy rate forming, wherein a material-locking connection between probe sleeve and probe core results and a rod is formed, wherein the rod represents a base body that is used for probe production, wherein a deformation speed reaches values greater than 100 m/s, and wherein the high energy rate forming includes explosive forming or magnetic forming.

Abstract: An X-ray source arrangement (10) for generating X-ray radiation (102), a method for operating the X-ray source arrangement (10), and an X-ray imaging apparatus (100) are provided. The X-ray source arrangement (10) comprises an X-ray tube (22), a converter arrangement (16) with an inverter (18) and a resonant converter (20) for providing a source voltage to the X-ray tube (22), a pre-controller (12), and a modulator (14). The pre-controller (12) is configured for determining a reference duty ratio (r, 26) of the resonant converter (20) as a continuous function of time based on a mathematical model of the resonant converter (20), and for providing a control signal (13) correlating with the reference duty ratio (r, 26) to the modulator (14). The modulator (14) is configured for determining a switching signal (15) based on the control signal (13), and for providing the switching signal (15) to the inverter (18) of the converter arrangement (16) for actuating the inverter (18).

Abstract: A method for mending damaged areas in fiber composite components formed from a plurality of unidirectional fiber layers includes the steps of automatically lifting at least one fiber layer of the fiber composite component at a cutting edge of the at least one fiber layer using a delaminating device, removing the at least one fiber layer in the extension direction of the fiber orientation of the at least one fiber layer, and separating off the removed at least one fiber layer in a defined manner at a separating edge defined by a separating device placed on the fiber composite component.
