Abstract: A device is for checking the plausibility of measured values of an axle load measuring system determinable via a sensor system, using which the axle load resting on all axles of a vehicle is determinable as a first total axle load value. The device has a comparator and a computing unit. A second total axle load value is computable via the computing unit. The first and the second total axle load value can be supplied to the comparator, a comparison between the two total axle load values can be carried out via the comparator, and, if there is a sufficiently large difference between the first total axle load value and the second total axle load value, an error message can be generated and/or a signal generator can be activated via the comparator. Manipulations and measurement errors on the axle load measuring system may be recognized in this way.

Abstract: A subterranean drilling assembly for linear and nonlinear drilling. A downhole motor-based bottomhole assembly with a bit deflection device includes a torque compensation device and is secured to the drill string via a swivel assembly to permit independent rotation of the string and the bottomhole assembly. In the case of a drill pipe string, the string may be rotated continuously during both linear and nonlinear drilling to reduce drag. In the case of a tubing string, the bottomhole assembly is rotated by the torque compensation device during straight drilling. In both cases, the torque compensation device is employed to adjust TFO for nonlinear drilling when the bottomhole assembly is not rotated. In an alternative embodiment, a torque-sensitive clutch is employed in lieu of the torque compensation device to provide rotational orientation to, and rotation of, the bottomhole assembly.
