Abstract: An adjusting drive for adjusting the rotational position of a large rolling bearing that comprises two bearing rings that can be rotated relative to each other, having an actuator for rotating the two bearing rings relative to each other. According to the invention, the actuating drive has a ring channel cylinder, which is formed in or on one of the bearing rings of the large rolling bearing, and at least one piston, which is received in the ring channel cylinder in a movable manner and is drivingly connected to the other bearing ring of the two bearing rings.

Abstract: The invention relates to a cellulosic fibre loaded with a biologically active substance formed by the steps of: a) producing a cellulosic fibre loaded with ion exchanger, b) after-treating the fibre thus produced with an aqueous solution of a metal salt which exhibits antibacterial activity and/or antiviral activity, and c) after-treating the loaded fibre with an aqueous fixing solution to convert the metal salt into a water-insoluble form. The cellulosic fibres thus produced can be used to form textile fabrics, wound dressings, sanitary products, specialty papers, packaging or filter materials.

Abstract: The present invention relates to a bucket wheel excavator whose bucket wheel is rotationally drivable and is supported at a pivotable bucket wheel boom and to a method of controlling such a bucket wheel excavator. In accordance with the invention, a mass flow and/or material flow adopted on the removal conveyor after a specific advance on the pivoting of the bucket wheel at the predetermined pivot angle speed is/are determined over the pivot angle, a desired mass flow and/or volume flow is/are specified on the removal conveyor, and then the previously specified pivot angle speed is automatically corrected using the determined mass flow and/or volume flow and the specified desired mass flow and/or volume flow to then perform the pivot cycle at the corrected pivot angle speed of the bucket wheel.

Abstract: The present invention relates to wind turbines with variable rotor blades whose pitch angles are adjustable. An adjustment unit is provided for adjusting the pitch angle of the rotor blades with a pivot bearing comprising at least two coaxial bearing rings that are rotatable against each other, at least one adjustment actuator for rotating the two bearing rings, and a supply unit for supplying the adjustment actuator with energy, whereby the adjustment actuator and the supply unit are disposed on opposite sides on a plate-shaped adjustment drive carrier part which is rotatably connected with one of the bearing rings and comprises a rotatable support bearing for the support of the adjustment actuator. A least one part of the supply unit is rotatably mounted on the carrier part such that the supply unit or its rotatably mounted part and the adjustment actuator are jointly rotatably mounted and/or swivel-mounted on the carrier part.

Abstract: The present invention is directed to an article of manufacture, which can be a fiber and or a film.

Abstract: A computer generates a modified list of search terms by adding synonyms of the search terms and terms that are related to the search terms to a list of search terms. The computer removes frequently used words from the modified list of search terms. The computer responds to a determination that a user has authorization to view a field of a document by adding to the modified list of search terms an encrypted version of a search term included in a list of search terms. A search using the modified list of search terms returns a result that identifies the document as a search result when either the unencrypted or the encrypted version of the search term is found in a list of index terms associated with the first document.
