In its filtering state, the filter is cone shaped which causes the blood to be filtered. Also disclosed is spray coating device and process for applying the coating. In a third step, the optical multiplex signal is, on the receive side, guided via a polarization control element to a polarization splitter that separates the transmitted optical multiplex signal into the first and second sideband-modulated signal. The base plate and the shoulder are formed from a single ferromagnetic monolithic block, and in that from the ferromagnetic monolithic block, at the first lateral face of the shoulder, a first recess is formed for housing the first plurality of magnetic conductors. This number is provided to the clocked system to re-synchronize the clocked system to the high frequency clock.
