A data stream that contains periodic time reference values referenced to a first reference clock is received for transcoding. The measuring tube communicates, by way of a first tube segment leading into the inlet end and a second tube segment leading into the outlet end, with a pipeline connected for allowing the fluid to flow through the measuring tube. The instruction word indicates the source module from which data is to be retrieved and the destination module to which data is to be stored. The sealant is disposed in a seal line region which is outside the alignment region. The external vessel ulterior space is coupled to the source of the particulate organic material so as to allow gases to pass from said space to the source and the inner vessel has an inlet coupled to the source through which the particulate organic material can pass and an outlet for allowing the charcoal to exit the inner vessel.
