Abstract: The resonant frequencies of a rotor supported on magnetic bearings, in particular a rotor of a turbomolecular vacuum pump, are determined. While the rotor is stationary or the rotor is rotating at a relatively low rotation frequency, mechanical oscillations of the rotor are generated by electromagnets in the magnetic bearing. The rotor oscillations are detected by rotor-position sensors in the magnetic bearing. The resonant frequencies of the rotor are determined from the detected rotor-position oscillations.

Abstract: An inking unit in a printing machine having an ink dispensing system comprising an inking roller and a form cylinder carrying at least one printing form.

The inking roller is also adjustable relative to the form cylinder. An engagement and/or disengagement of the inking roller relative to the form cylinder and/or an engagement and/or disengagement of a print blanket cylinder or form cylinder relative to the impression cylinder is performable such that print sheets become can be imprinted with a residual ink image by residual ink remaining on the plate cylinder or print blanket cylinder in a printing ON setting with the ink supply disengaged.

Abstract: Temperature control of the coating medium is performed to influence the processability of coating media in an applicator system. In order to operate without losing efficiency, devices acting directly from the inside or the outside for heat supply or dissipation are connected to the elements guiding the coating medium. The temperature of the coating medium is influenced by measuring the temperature within the coating medium and, if necessary, at the elements guiding the coating medium.
