摘要： A test device to localize a partial discharge in or at an electrical component may include at least one antenna to capture an electromagnetic wave caused by a partial discharge in the electrical component. The test device includes multiple microphones arranged in an environment around the electrical component. The microphones capture sound waves caused by the partial discharge. It is examined if an intensity of the electromagnetic wave exceeds a first limit value and/or the intensity of the sound wave captured by one of the multiple microphones exceeds a second limit value. Depending on the captured sound wave and/or the electromagnetic wave and on the examination relating to the first and/or second limit value, a location of the partial discharge can be determined.

摘要： A coolant distributor for a machine configuration. At least one coolant forward flow inlet opening and at least one coolant return flow outlet opening as well as multiple coolant forward flow outlet openings and multiple coolant return flow inlet openings are formed in a distributor body of the coolant distributor. The coolant forward flow inlet opening is fluidically connected by way of a forward flow chamber present in the distributor body to the coolant flow outlet openings, and the coolant return flow inlet openings are fluidically connected by way of a return flow chamber to the coolant return flow outlet opening and the coolant forward flow inlet opening is separated fluidically within the distributor body from the coolant return flow outlet opening, and wherein the distributor body is composed of two identical parts, which between them form the forward flow chamber and the return flow chamber.

摘要： An assembly for acoustically influencing toothed wheels, including at least one first toothed wheel having teeth and one second toothed wheel having teeth, wherein the teeth have flanks, wherein at least one flank of a tooth of the first toothed wheel can be engaged with a flank of a tooth of the second toothed wheel, wherein at least one flank of a tooth of the first toothed wheel forms a contact zone or, in the ideal case, a contact line with an engaging flank of a tooth of a second toothed wheel, wherein the contact zone or the contact line is formed at an angle αAq, in particular between 5° and 85° or between 95° and 175°, in relation to an axis of an undulation, a microangle distribution, and/or a microangle periodicity of the engaging flank of the tooth of the second toothed wheel.
