Abstract: A method for detecting damage to a hollow shaft is disclosed. A sensor for transmitting and receiving a signal is positioned at an end face of the hollow shaft, a signal is transmitted and an echo of the signal is received, the signal propagation time from the time of transmitting the signal until receiving the echo is determined, and the signal propagation time is compared to a predetermined intended value, and with a warning being emitted in the case of a deviation.

Abstract: The invention relates to a device (14) and to a method for the contactless detection of a torque of a shaft (10) and/or torsional natural frequencies and/or torsional oscillations. The shaft (10) contains a ferromagnetic material. A measurement head (16) facing toward a shaft wall (12) comprises an excitation coil (22) which couples a magnetic field into the shaft (10). The measurement head (16) furthermore contains a number of measurement coils (24, 26, 28, 30), which measure the magnetic field emerging from the shaft (10).

Abstract: A method for the classification of superabsorber particles is disclosed, in which the superabsorber particles are put onto a top screen deck of a screening machine having at least two screen decks with a different hole size, the superabsorber particles which are smaller than the holes of the respective screen deck respectively falling through the holes and the superabsorber particles remaining on the screen deck being removed via an extraction point. Balls are positioned on each perforated plate, which balls are propelled upward by the movement of the perforated plate and strike from below the screen deck respectively lying above, wherein the balls have a stiffness in the range from 40 to 100 N/mm and a damping in the range from 1 to 4%. A machine for carrying out the method also is disclosed.
