A pallet having first and second decks with at least two post assemblies extending between the first and second decks to maintain the first and second decks at a distance from one another. The distributed database may comprise a plurality of private address data. The connection part 22 is tapered toward the downstream exhaust pipe 12 and the diameter of the connection part 22 is gradually reduced and its opening is welded into the opening of the downstream exhaust pipe 12. When searching for and identifying the synchronization channel, the pilot symbols and, possibly, further symbols and sequences which are known in the receivers, are evaluated to estimate the delay times and the complex amplitudes, of the mobile radio channel responses. Therefore, the elements can be heated and cooled in a short period of time in which constant geomagnetism can be ensured. Consequently, the contamination from the metal impurities in the active layer can be reduced.
