Abstract: A vehicle wheel suspension includes a suspension spring and an additional spring element. The additional spring element is disposed in a working chamber of a hydraulic cylinder. The working chamber, in hydraulic terms, is configured to be completely shut off by a check valve and the volume thereof with an opened check valve while activating a vehicle drive apparatus with braked vehicle wheels being variable by the anti-dive angle and/or the anti-squat angle. For such a volumetric variation of the working chamber, a hydraulic medium is flowable through the opened check valve.

Abstract: A method is provided for charging a battery-operated vehicle having a chargeable traction energy store and a system for autonomously guiding the vehicle with a charging vehicle having an energy generator and/or an energy store. The method forms at least one electrical coupling between the battery-operated vehicle and the charging vehicle via an autonomous driving manoeuver of the battery-operated vehicle and/or the charging vehicle. A charging of the traction energy store of the battery-operated vehicle occurs via the energy generator and/or the energy store of the charging vehicle during the driving of the paired battery-operated vehicle and charging vehicle.

Abstract: A vapor-deposition device for coating two-dimensional substrates with an organic material. The substrates can be positioned within a vacuum chamber above a process chamber or can be moved past the latter by a transport device. A vaporizer for an organic coating material is arranged within the process chamber and opposite the substrates. The process chamber is delimited laterally by shields which, opposite the substrates, extend as far as a feed device for the coating material. The vaporizer includes the feed device for the coating material and radiant heaters underneath the same. This arrangement can achieve, with a high vaporization rate, good homogeneity of the layer thickness and of the layer stoichiometry.

Abstract: The invention relates to an electronic circuit and a method for feeding power to at least one electrode of an alternating-current electric-arc furnace, particularly for melting metal. Known circuits of this type typically comprise a series connection with a transformer for providing a supply voltage for the electric-arc furnace from a power grid (1) and a AC power controller (8) connected between the transformer (6) and the electrode (11) for regulating the current through the electrode (11). According to the invention, a further development for such electronic circuits is proposed, which development has a simple design, is inexpensive and prevents overload of the AC power controller (8) even in operating modes of the electric-arc furnaces at high electrode currents. This further development provides to bypass the AC power controller with a bypass switch (9) that is opened or closed with the help of a controller as a function of the amount of current flowing through the electrode (11).

Abstract: A single wheel suspension of a non-steerable wheel of a two track vehicle includes two links pivotable relative to each other in respective planes, each being inclined less than 10° relative to the longitudinal and vertical directions of the vehicle. A first link, extending approximately in the longitudinal direction, functions as a wheel carrier. The first link is supported with an end section on the vehicle body via a pendulum support, which extends essentially in the vertical direction. The second link, extending approximately in the longitudinal direction, is supported in an articulated manner, on one side, on the body with only one kinematic rotational degree of freedom and on the other side to the first link between the wheel bearing and a pendulum support fastening point with only one kinematic rotational degree of freedom. No other wheel guiding link is provided, except for a connecting element.
