Abstract: A measurement apparatus for alternating currents and voltages of a physical plasma ignited by applying an alternating high voltage from an alternating high voltage source to a plasma electrode via a high voltage line comprises a current transformer having a measurement winding on a ring core and a cable guide guiding the high voltage line through the ring core. A first measurement alternating voltage dropping over a measurement resistor connected between ends of the measurement winding is a first strictly monotonic increasing function of an amperage of the alternating currents flowing through the high voltage line. A second measurement voltage dropping over a measurement capacitance connected between a center tap of the measurement winding and a reference potential connector is a second strictly monotonic increasing function of an amplitude of the alternating high voltage applied to the plasma electrode with respect to a reference potential at the reference potential connector.

Abstract: The invention relates to a low-pressure coating system and a method for coating particle or fibre collectives by means of physical or chemical vapour phase deposition. A deagglomeration unit is used, by means of which the particle or fibre collective is separated and then coated. These particles are used for example as active material for batteries and capacitors and as 3D printing powder or colour pigments. The fibres are used for example for textiles, membranes, filters or composite materials.

Abstract: To dry a hand with fingertips and a carpus, the palmar aspect and the dorsal aspect of the hand are blown dry, starting from the fingertips, by a pair of planar gas jets, wherein the gas jets of the pair run towards each other in the direction from the carpus to the fingertips at an angle of less than 180°. By applying high-voltage AC pulses with respect to ground to dielectrically shielded electrodes arranged next to both planar gas jets, direct discharges are obtained across the hand on the palmar aspect thereof and on the dorsal aspect thereof.
