Abstract: The present disclosure relates to an emptying detection device configured to provide an emptying signal to an emptying system for emptying a container, such as a dosing system including a suction lance, a corresponding suction lance and a corresponding emptying system. The emptying detection device is configured to determine a level of a liquid in the container relative to the emptying detection device, the emptying detection device comprising: a sending and receiving unit being configured to emit electromagnetic waves and to receive electromagnetic waves, and a transponder unit being configured to receive electromagnetic waves from the sending and receiving unit, and to emit a signal in response to the received electromagnetic waves. The sending and receiving unit is configured to emit electromagnetic waves at a frequency for which the liquid has a non-negligible absorption coefficient, and to provide an emptying signal to the emptying system in response to receipt of the signal from the transponder unit.

Abstract: The present disclosure relates to a grinding machine. More particularly, the present disclosure relates to a centerless grinding machine comprising a damping device. The present disclosure also relates to a spindle for a grinding machine, and to a damping device for a spindle of a grinding machine, particularly for a grinding spindle or regulator spindle of a centerless grinding machine, wherein the damping device comprises at least one damping unit including an auxiliary mass section, an elastic section and a damping section, which are integrated in the spindle, and which jointly define a damped vibratory system for increasing the dynamic stiffness of the spindle.
