The tool comprises one or more core-coil assemblies 2 jacketed in an non-magnetic and electrically insulating, tubular outer housing, 10. The housing enables high power transfer efficiency. A structural skeleton 20 extends longitudinally through the tool for axially reinforcement. The core-coil assemblies 2 are encapsulated in epoxy 77 to mechanically rigidify and protect them as well as to isolate the coil windings 51 from the power bus 23 extending longitudinally of the core-coil assemblies through a peripheral busway 60, 61.

A method and a magnetic levitation vehicle operating with this method are described. For the control of support gaps (10a, 10b) that are formed during operation of the magnetic levitation vehicle (1) between a track (2, 3, 4) and a number of carrying magnets (6a, 6b) fastened to said magnetic levitation vehicle (1) and provided with windings (16a, 16b), wherein at least two carrying magnets (6a, 6b) in adjacent positions act upon a suspension frame (8) of said magnetic levitation vehicle (1), the electrical currents flowing through the windings (16a, 16b) are so controlled that the support gaps (10a, 10b) between these two carrying magnets (6a, 6b) and the track (2, 3, 4) adopt pre-determined nominal values (na, nb). In accordance with the invention and in case that the currents through the windings (16a, 16b) of the adjacent carrying magnets (6a) are different under normal conditions, the nominal values (na, nb) for the support gaps (10a, 10b) are altered such that the current through the windings (16a or 16b) of a carrying magnet (6a, 6b) with the lower electric current is increased and/or the electric current through the winding (16b and/or 16a) of a carrying magnet (6b, 6a) with the larger electric current is reduced.

摘要:
A method and device for sterilizing containers in which a plasma treatment is executed through excitation of an electromagnetic oscillation so that the plasma is excited in a vacuum in the vicinity of the container regions to be sterilized. Between arrival and discharge, the container regions to be sterilized are moved closer to the oscillation-generating device in the chamber, with continuous movement of the container and/or of the oscillation-generating device for one or more predetermined time intervals in such a way that a plasma is excited in these regions inside and/or outside the container. The chamber is provided with a transport apparatus inside it, which produces an essentially rotating motion of the container during the transport from the arrival to the discharge in the chamber.

摘要:
The invention relates to a method of preparing turbine blades for spray coating their blade region that is subjected to the medium flowing through during operation in a spray coating apparatus, in which the turbine blade is inserted with its blade root into a cavity of a mounting in such a way that it protrudes with the blade region that adjoins the blade root from an opening of the cavity to form a gap between the rim of the opening and the turbine blade, and in which the gap is bridged by a shielding fixed on the mounting, which is characterized in that a shielding layer of a plastic which is resistant during the spray coating is used for the shielding, the shielding layer being arranged in such a way that it reaches up to the boundary between the blade root and the blade region.
