The disclosure is directed to a cutting process involving: creating a starter crack using a scribe wheel, application of laser or electrothermal heating, and subsequent cooling from a gas or an aerosol jet, as the laser beam and cooling jet move along the desired cutting line. To limit the temperatures in a subsequent strongly exothermic CO shift reaction to adjust the H2CO ratio, the crude gas which has been freed of dust flows through two shift reactors arranged in series. In accordance with an aspect, the synchronization start position determination unit establishes the start position of the synchronization search window with reference to a calculated distance of the mobile station from the destination base station.
