The invention relates to piping for use as a pyrolysis tube in a cracking furnace. The device includes a pivot mechanism for reliably controlling the orientation of the animal during upward and downward travel on the transport system. The output of the frequency prediction unit is used as the active frequency update values during non quiet periods. Also taking into account stand-alone business models covering special cases such as loose content bundles, the resulting composite business models determine content access conditions plus the levying and distribution of fees between the participating stakeholders. The guide-press member is pivotally provided with a press roller and an actuating wheel having its surface annularly disposed with several flanges.
