Abstract

The appts. comprises an information generator, connected to a transmitter unit (4) producing the pressure impulses. At the surface, a receiver intercepts and evaluates the signals. In the novel transmitter unit, within the flow, is an elastic flow resistance body (6). An actuator causes variation in the cross section (Q) available for flow. These variations correspond to the required signal pressure impulses.
