Abstract: A coupling arrangement for an agricultural tractor includes a drawbar having a first bar section, which is mounted in a longitudinally movable manner in a holder for attachment to an underside of a differential housing of the agricultural tractor, and a second bar section, which is situated opposite the first bar section and is guided in a longitudinally movable manner within adjacent upper and lower supporting cheeks of a coupling carrier plate provided for attachment to the rear of the agricultural tractor. The drawbar is movable into a plurality of coupling positions by longitudinal movement and can be locked therein with respect to the coupling carrier plate via at least one securing element.

Abstract: A method for checking at least one subregion of a component, in particular a component of a turbomachine, including at least the steps of a) providing a blank; b) producing at least the subregion from the blank by machining the blank using at least one tool and using at least one force sensor-to record at least one force curve of at least one force acting during machining on the at least one tool; c) checking whether there is at least one deviation-of the at least one force curve from at least one predetermined target curve-of the at least one force curve, the at least one deviation-characterizing at least one material defect-contained in an unmachined segment of the subregion. A checking device for checking at least a subregion of a component is also provided.

Abstract: A method for monitoring a production process with regard to quality is disclosed. The method includes: a) breaking down the production process into a sequence of individual steps, defined by a sequence of control commands for a production program for carrying out the production process on a machine tool; b) generating at least one signal template per individual step of the production process from the control commands for the individual steps, each signal template corresponding to a theoretical signal curve for a parameter which may be measured upon executing the production process; c) measurement of a signal curve for at least one parameter per individual step during the execution; and d) comparison of the or each measured signal curve with the respective arithmetically generated signal template, wherein a qualitatively poor production process is determined if the measured signal curve deviates from the signal template by more than a given tolerance.

Abstract: The present invention relates to a method for determining a selected machining quality of components in a manufacturing process, particularly during metal cutting, having at least the following method steps of determining process-relevant variables by sensors and/or from the data stream in the machine controller, extracting variable curves characteristic for the respective machining process, selecting a number of different characteristics of the extracted variable curves, the linking of which enables a clear assignment to the selected machining quality, and multivariate linking of the selected characteristics to a characteristic pattern correlating with the selected machining quality.

Abstract: A chuck-integrated force-measuring system for determining cutting forces at the cutting tool tip of a rotating tool, for example a drill or milling cutter having at least one measuring sensor, as well as a measured-value processing station. The at least one measuring sensor is designed as a strain sensor which is placeable on a tool holder of a machine tool. A measuring hub assembly is also provided which is insertable as an adapter piece into the chuck of the machine tool and is designed with its own chuck for receiving the tool, the at least one measuring sensor being integrated in the adapter piece.

Abstract: In an apparatus for orbit control of at least two co-located geostationary satellites a single interface is provided in the form of an orbit database for exchanging orbit and maneuver data between four independent decoupled function blocks of an orbit control system having a matched function scope, i.e. between a first function block for orbit determination and maneuver estimation/maneuver calibration, a second function block for maneuver planning, a third function block for monitoring the relative movement and a fourth function block for predicting specific events and ephemerides (FIG.
