Abstract: Techniques produce electrostatically charged fibres, and in particular produce an electret fibre construct, where fibres are produced from a plastics and/or natural-origin material, where a polar liquid is atomized using a gaseous pressure medium to produce a treatment aerosol and where the fibres are treated with the treatment aerosol for electrostatic charging, wherein the atomizing is undertaken with a quotient of the volume flow of the polar liquid in litres per second and the positive pressure of the gaseous pressure medium in hectopascals of 0.004 to 0.008.

Abstract: To combine specific information transmitted in the form of multiframes (i.e. signalling information in TDMA) channel by channel at the receiving end, this information is written into a RAM in parallel in order of receipt. The addresses of the RAM are divided into channel and frame addresses which are stepped on independently of each other for writing and reading. Writing and reading alternate in quick succession. When the end of a multiframe is detected in a channel, this channel address is retained during reading and the signalling information of this channel, starting with the beginning of the multiframe, is read out in parallel and translated into serial form. To do this, each channel has the same sufficient time available.
