Abstract: Described herein are a method for transferring an embossed structure, which includes at least the steps (1-i) and (2-i) or (1-ii) and (2-ii), where steps (1-i) and (2-i) or (1-ii) and (2-ii) are carried out using an embossing tool (P1) including at least one embossing die (p1), where the embossing die (p1) of the embossing tool (P1) is pretreated, before the implementation of step (2-i) or before the implementation of step (1-ii), with at least one organic solvent and/or at least one reactive diluent, and also a method of using a corresponding pretreated embossing tool (P1) including at least one embossing die (p1) for the purpose of transferring an embossed structure in such a way.

Abstract: The invention relates to a method for the production of a catalyst system comprising a catalytically active component, in particular a supported catalyst, and to a catalyst system as such. The present invention also relates to uses of the catalyst system according to the invention and further to protective materials as well as filters and filter materials which are produced using the catalyst system according to the invention or which comprise such a catalyst system.

Abstract: An axially supporting rolling-element bearing of a rolling mill shaft includes an inner ring having a raceway, an outer ring having a raceway and a plurality of rolling elements on the raceways between the rings. An outer surface of the outer ring includes an opening such as a groove that faces radially outward and contains a seal element. The seal element includes a seal lip that extends out of the groove. When the rolling element bearing is placed in a bore of a housing, the outer ring is spaced from the bore by the seal element.

Abstract: A generator rotor assembly (42) comprises a cylindrical ring structure (46) defining a central hollow portion and arranged to rotate around a rotational axis. The cylindrical ring structure (46) comprises a plurality of permanent magnet packages (48) arranged coaxially around the rotational axis, the permanent magnet packages (48) comprising a plurality of coaxially stacked ring-shaped segmented layers (80), a plurality of tie rod holes (86) and a plurality of tie rods (54). The coaxially stacked ring-shaped segmented layers (80) comprise a plurality of contiguous segment sheets (82) arranged around the rotational axis to form the ring-shaped layer, the stacked layers (80) being staggered such that segment breaks between two contiguous segment sheets (82) in one of the layers are angularly offset with respect to segment breaks between two contiguous segment sheets (82) in an adjacent layer.

Abstract: A rolling-element bearing assembly includes a rolling-element bearing and an oil conditioning system for conditioning oil used to lubricate the bearing. The bearing has an inner ring and an outer ring and a plurality of rolling elements rotatably disposed between the inner ring and the outer ring. The bearing includes openings for discharging oil from the bearing and for introducing oil into the bearing, and the openings are connected to the oil conditioning system. A raceway of the inner ring and/or a raceway of the outer ring is coated with a first coating, and the rolling elements are at least partially coated with a second coating that is different from the first coating.
