Abstract: A method for operating a test apparatus including a plurality of shared resources is shown, wherein the plurality of shared resources can be used in different instruments. The method includes blocking a first set of resource blockers when a first instrument, which requires a first subset of the shared resources, is to be executed. Furthermore, the method tries to block a second set of resource blockers, when a second instrument, which requires a second subset of the shared resources, is to be executed. Therefore, the first set of resource blockers is different from the second set of resource blockers and a plurality of resource blockers are assigned to a shared resource, which is involved in a conflicting combination of instruments and in a non-conflicting combination of instruments.

Abstract: A technique of safeguarding equipment involves deriving a pressure pulse amplitude based on operation of a pump of the equipment, and performing a comparison operation that compares the pressure pulse amplitude value to a predefined threshold. The technique further involves performing, in response to a result of the comparison operation indicating that the pressure pulse amplitude value has fallen below the predefined threshold, a remedial activity to prevent damage to the equipment or to prevent endangerment to persons affected by the failure of the equipment. For example, in the case of an unmanned aerial vehicle (UAV), the remedial action may be to transit the UAV from a densely populated area to a rural area where landing may be possible without injuring persons or damaging the UAV.

Abstract: The invention relates to a blade for a turbomachine, comprising a blade element with a suction side and a pressure side, which extend between a leading edge and a trailing edge of the blade element, as well as a blade root for connection of the blade at a main rotor body, wherein the blade comprises a crack-affecting device, which, in the radial direction, has an altered cross-sectional geometry in comparison to an aerodynamically optimized blade profile. The invention further relates to a rotor for a turbomachine having at least one such blade, a turbomachine having at least one such blade, and/or with such a rotor as well as a method for producing a blade.

Abstract: In a method and a machine tool for machining metallic workpieces, a cooling device is provided to supply a cryogenic coolant to a first tool and a precooling device is provided to supply the cryogenic coolant to a second tool. The first tool is held in a first chuck and processes a workpiece, with the first tool during processing being cooled via the cryogenic coolant. The second tool is held in a second chuck and will subsequently be used for processing the workpiece. The second tool is supplied via the precooling device with the cryogenic coolant and thus cooled to the operating temperature required for processing. Due to the fact that the second tool is precooled to the required processing temperature, after the change of tools, the processing of the workpiece can be continued immediately. By precooling the second tool during the primary processing time, the total processing time of the workpiece is reduced, providing the machine tool with higher productivity.

On the rotating part, several tool holders are mounted on the circumference for holding tools to which a cryogenic cooling medium can be fed by means of a first feed line and a respective second feed line. The first feed line can be moved in a linear manner in at least some sections by a linear actuator whereby the first feed line is connected in a first position with the second feed line belonging to the tool in work position and in a second position is disconnected from the second feed lines for changing the rotary position of the rotating part. The tool turret enables the cryogenic cooling medium to be fed to the tools in a simple and reliable manner.
