Abstract: A device for the ionization of gaseous media, comprising a feed channel (101) having a gas feed, a distribution channel (104) having at least one gas outlet, and at least one ionization unit (304), wherein the at least one ionization unit (304) is designed as a connecting channel from the feed channel (101) to the distribution channel (104) and is provided with an electrode (102) and an associated counter electrode (106). The electrode (102) is configured to ionize gas flowing through the ionization unit (304) from the feed channel (101) to the distribution channel (104), wherein the gas flows around the electrode (102), and the at least one gas outlet is designed in the form of one or more nozzles (107) or a plurality of openings (107).

Abstract: In a magnetically borne position-stabilizable flywheel, the force generation systems (at least for the radial drive) are designed in accordance with the electrodynamic principle and disposed in the interior of the wheel hub. The coils are situated on the stator and the associated permanent magnets on the rotor. Undesired oscillations are effectively damped. As a result of the displacement of the drive into the wheel hub, it is possible to use small coils. The swivel range of the wheel is sufficiently large.

Abstract: A stepping motor for rotating a body through small angles of rotation, the stepping motor having a stator and a rotor, an actively moveable connection unit for selectively connecting each of the stator and rotor to the body, and a drive which can be triggered and acts on the rotor. For performing an individual rotational step, the triggering of the drive and the connecting of the rotor with the body are essentially effected during a given period of time, and each time after performing a rotational step, triggering of the connection of the stator with the body takes place in order to maintain the body in the particular position attained.
