Abstract: An applicator syringe (1) is disclosed containing a sterile solution having a medical active substance, in particular for introducing the solution containing the active substance via a urinary tract and/or bladder catheter into the bladder of a patient. The applicator syringe (1) includes a cylindrical jacket (2), which is closed by a syringe cover (3), which is integrally formed with the jacket (2) and includes an outlet opening (5) and is formed from a cycloolefin copolymer (COC). The applicator syringe (1) furthermore comprises a plunger tip made of an isobutene-isoprene rubber, which is halogenated in particular. The sterile solution containing the medical active substance is arranged in a cavity (6) delimited by the cylindrical jacket (2) having syringe cover (3) and the plunger tip.

Abstract: A portable crane assembly for servicing a wind turbine. The crane assembly includes a first primary support member and a second primary support member being rotatably attached to one another. The first primary support member is configured to attach to a wind turbine component. The second primary support is coaxially rotatable with respect to the first primary support member. The crane assembly further includes a boom member pivotably attached to an end of the second primary support member. The portable crane assembly is disassemblable into components that can be manually carried. A wind turbine servicing system and a method for servicing a wind turbine are also disclosed.

Abstract: A method for operating a wind turbine generator includes generating at least one of a plurality of rotor shaft angular displacement values, a plurality of rotor shaft angular velocity signals, and a plurality of rotor shaft angular acceleration signals. The method also includes determining a torsional moment within a rotor shaft, and modulating at least one of a wind turbine generator yaw orientation and a blade pitch orientation as a function of the determined torsional moment.
