Abstract: A method for preparing a cooled spinning solution suitable for forming a regenerated cellulosic shaped body by extrusion into a coagulation bath. The method comprises at least one conditioning step during which the spinning solution is distributed over a cooled surface by at least one distributing blade.

Abstract: A method and a production facility for producing regenerated cellulosic fibers. A spinning solution is extruded into a coagulation bath which contains a salt and preferably an alkali. The spinning solution comprises cellulose dissolved in an aqueous solvent comprising NaOH and ZnO and the coagulation bath has a pH-value of at least seven. The fibers in the fiber tow are fixated and stretched to essentially their final cellulose specific diameter before being cut to staple fibers in an undried state.

The spinning solution comprises cellulose dissolved in an aqueous solvent comprising NaOH and ZnO and the coagulation bath has a pH-value of at least seven. The processing facility comprises a cutter to cut the fiber tow in an undried state into cut fibers, a fleece-forming device for suspending the cut fibers and collecting them in form of a non-woven fiber layer, and at least on pressing device for pressing the non-woven fiber layer, thereby imposing a natural crimp on the fibers.

Abstract: An audio reproduction system is divided into a central wave-field synthesis module and a plurality of loudspeaker modules disposed in a distributed way, wherein synthesis signals for the individual loudspeakers as well as corresponding channel information associated to the synthesis signals are calculated in the central wave-field synthesis module. The synthesis signals for a loudspeaker as well as associated channel information will then be transmitted to respective loudspeaker modules via a transmission path, wherein every loudspeaker module obtains the synthesis signals and associated channel information intended for the loudspeaker associated to the loudspeaker module. A distributed audio rendering and digital/analog converting takes place in the loudspeaker module to generate the actually analog loudspeaker signals in a distributed way in spatial proximity to every loudspeaker.

Abstract: In a reproduction environment, speakers are grouped in directional groups, wherein the directional groups overlap with respect to the associated speakers so that speakers are present which have a speaker parameter having different values for the first directional group and the second directional group. A controller for controlling a plurality of speakers has a provider for providing a source position of an audio source, wherein the source position is located between the first directional group position and the second directional group position. The apparatus further has a calculator for calculating a speaker signal for the at least one speaker, based on the first parameter value for the speaker parameter and based on the second parameter value for the speaker parameter.

Abstract: The invention relates to an automatic dishwasher (1) which can be operated in several operating modes (71, 72, 73, 74). The automatic dishwasher (1) proposed according to the invention can be switched from a first operating mode (71) to a second operating mode (72) only when a third operating mode (73) called kosher operation is executed. During the third operating mode (73) “Kosher operation”, the interior of the automatic dishwasher (1) is cleaned with a heated cleaning fluid whose temperature lies above the maximum temperature occurring in the normal operation of the automatic dishwasher (1). The endless conveyor belt (10) of the automatic dishwasher (1) is treated by a cleaning device (43) during the third operating mode (73) “Kosher operation”; moreover, a water tank (25) of the automatic dishwasher (1) is heated to a higher temperature than the temperature which occurs in the normal operation of the automatic dishwasher (1).

Abstract: For reducing Doppler artifacts in the wave-field synthesis due to delay changes from one time to a second time, first, the delay for the first time and the delay for the second time are determined. Then, a value of an audio signal delayed by the first delay for the current time and the value for the audio signal delayed by the second delay for the current time are determined. Then, the first value is weighted by a first weighting factor and a second value is averaged with a second weighting factor, whereupon the two weighted values are added up to obtain a discrete value for the current time of the component in a loudspeaker signal for a loudspeaker based on a virtual source. Thus, by knowing a delay present at a later time, panning is obtained from a delay to a subsequent delay, which reduces undesired Doppler artifacts.
