State of the art: it is known for the individual cells of an ATM data stream to be evenly distributed in the first half of a switching network and to be fed to the destination in the second half of the switching network only. The switching network has multiple stages (three, five, seven stages); the individual stages are three-stage non-blocking modules (e.g. of the Clos type). Fundamental pr...

The present invention relates to a method of producing plastic comonomers and plastics from fats and oils containing unsaturated fatty acids, crude unsaturated fats and oils being oxidised by performic acid or peracetic acid to give epoxy or hydroxy compounds and the latter being then reacted to give polymers, using bifunctional or multifunctional compounds that are capable of reacting with epoxy ...
