Abstract: An arrangement having at least two generator bars for a stator of an electrical generator which are electrically connected to one another via a respective bar end is characterized, according to the invention, by the fact that the respective bar ends, which are electrically connected to one another, of the at least two generator bars are braced with respect to one another by means of a tape.

Abstract: A method determines a switching time of an electric switching device containing an interrupter path disposed between a first line section subjected to a driving voltage and a second line section that forms an oscillating circuit after the switching device undergoes a shut-off step. The method is used for determining the best possible switching time for an electrical switching device to minimize transient voltage surges. It is proposed that either—a temporal progression of a voltage that develops along the interrupter path is determined during a scanning period; or that—a temporal progression of a voltage that develops along the interrupter path is determined during the scanning time.

Abstract: A laminated core testing device for testing laminated cores in a generator is provided. The laminated core testing device includes an exciting winding situated parallel to a rotation axis of the generator and connected to a secondary alternating current generator, and further includes an infrared image acquisition device for acquiring infrared recordings. The secondary alternating current generator has a controllable frequency converter, and the secondary alternating current generator, at a frequency ranging from 400 Hz to 600 Hz, provides, in a single-phase manner, an output of 200 kW with a controllable output voltage ranging from 0 V to 3.0 kV.

Abstract: A continuous process for dyeing yarns with vattable dyes comprises, in continuous yarn dyeing ranges, metering an aqueous dye dispersion into the circulating chemical liquor.

Abstract: The mass-transfer apparatus is based on the principle of the gas washer in which a liquid is injected into the hot gas stream. The apparatus consists essentially of a gas feed pipe (1), which discharges vertically into an injection chamber (2) of greater diameter. Connected to the injection chamber (2) is a mass-transfer duct (12) with a diffuser (13). The injection chamber (2) is closed at its upper end against the gas feed pipe (1) with an annular roof (4). In the annular roof (4) are arranged liquid nozzles (5), directed at an angle downwards. The gas feed pipe (1) does not terminate flush with the annular roof (4) but is extended into the injection chamber (2) in the form of a gas skirt tube (8), so that the liquid nozzles (5) in the annular roof (4) are protected from the hot gas stream.
