Abstract: A resistance covering for a DC insulation system may be a matrix material with particles embedded therein, the particles having an aspect ratio greater than 1. The matrix material is flexible to such an extent that the particles align depending on an electric field strength. The particles can align in the electric field and thus a breakdown voltage of the resistance covering is increased. A DC insulation system may have the resistance covering.

Abstract: A thermoelectric generator pipe for producing electrical energy, surrounds a heat source or a heat sink. The generator pipe is formed by a helix structure having an inner and outer conductor strips that are electrically conductive. The conductor strips have substantially the same width and are wound with the same pitch. Between the inner and outer conductor strips, first and second intermediate axial spaces are formed, which are each arranged between one edge of the inner conductor strip and the edge of the immediately adjacent outer conductor strip. The intermediate spaces are formed as a double helix. First and second layers are arranged respectively in the first and second intermediate spaces. The first and second layers are formed respectively from n-doped and p-doped, thermoelectric and percolating particles. The generator pipe is slit subdivided in the axial direction to produce sections that form thermoelectric elements connected in series.

Abstract: A method is provided for producing an electrical insulation paper having a particle composite. The method involves mixing a dispersion of particles in platelet form, a carrier fluid and a functionalizing agent which is distributed in the carrier fluid and has a proportion by mass in the dispersion corresponding to a predetermined mass ratio based on the proportion by mass of the particles. The dispersion is sedimented, such that the particles in platelet form are arranged in essentially plane-parallel layers in the sediment. The carrier fluid is removed from the sediment. Energy is introduced into the sediment to overcome the activation energy of that chemical reaction of the functionalizing agent with the particles which forms the particle composite from the sediment with coupling of the particles via the functionalizing agent. The mass ratio is predetermined such that the particle composite has a porous structure. The insulation paper is thereby produced.

Air pressure applied to the air outlet (5) can lift the valve element (7) off a valve element seat (9) of the valve body (6) to allow air to flow past the valve element (7) to the air inlet (4).

Abstract: A varistor, or voltage-limiting composition has a polymer matrix and a particulate filler containing a partially conductive material applied to an electrically non-conductive carrier material. The carrier material has a lower density than the partially conductive material, so that the settling rate of the filler in the polymer matrix is reduced. The voltage-limiting composition can therefore also be used as a lacquer or for prepreg materials. A body which acts as a varistor may be produced using a composition of this kind by a method that includes annealing. The varistor may be used for surge arresters, in particular in medium-voltage systems, low-voltage systems, cable connections and cable fasteners.

Abstract: A method of selecting an audio source includes the step of providing an audio system that includes a source of audio data which can be supplied to a speaker to produce sound. A portable audio source device is enabled to be operatively connected to the audio system. When the portable audio source device is operatively connected to the audio system, the audio system automatically stops supplying audio data from the source of audio data to the speaker and starts supplying audio data from the portable audio source device to the speaker to produce sound.
