Abstract: A track for track bound vehicles, in particular for light rail vehicles. Includes a support element for supporting an electric conductor arrangement, which is adapted to produce an alternating electromagnetic field and—thereby—to transfer electromagnetic energy vehicle on the track. The support element confines spaces for receiving lines and/or wires of the conductor arrangement. An electrically conductive shield for shielding the alternating electromagnetic field extends along a plane below the spaces. A housing for receiving a power supply device for supplying electric power to the conductor arrangement is also provided.

Abstract: In order to be able to achieve, in yarn manufacture, the very high speeds required by the textile industry in open-end spinning devices, for the purpose of increasing production, and in order to achieve high operating reliability and a long life of the spinning devices, the rotor which rotates at high speeds and is subject to a variable imbalance and which is guided in gas-dynamic radial plain bearings is guided in a bearing carrier which is elastically pivotable in relation to the rigid bearing journal. At the same time, the bearing journal is connected, but so as to be elastically pivotable, to the bearing carrier via a bearing-body joint. A first gas-dynamic radial plain bearing, which is located in the region in the center of gravity of the rotor, is arranged on the bearing carrier, and a second gas-dynamic radial bearing is arranged at the opposite end of the bearing carrier.
