Abstract: A system and a method for warning a person, steering a displaceable object, of an intrusion of the object into a section of a traffic route that is at least temporarily protected. The system includes an activatable device for determining the location of the displaceable object in relation to a threshold; a device for comparing the distance of the displaceable object from the threshold with a threshold value, to determine whether the threshold has been violated; and a transmitter and a receiver situated in the displaceable object. If the threshold is violated and simultaneously activated, the transmitter emits warning signals that are tuned to the receiver. The receiver of the displaceable object supports a plurality of predefined radio channels and the transmitter sends the warning signals on all the channels. The system further has a device situated in the object for acoustic and/or optical emission of the warning signals.

Abstract: A conveyor system for moving flowable bulk material is equipped with a funnel (12) that has a circular funnel inlet (13) formed by a cylindrical wall section (16′) and an orthogonal funnel outlet (14) formed by eight funnel walls (18; 17, 17A; 17′, 17″) connected at one end to the cylindrical wall section (16′) and forming at the opposite end the orthogonal funnel outlet (14). Four walls (17, 17A; 17′, 17″) of the eight funnel walls are flat or plane and form funnel side or lateral walls. The remaining four four walls (18) have a curved cross-section and form funnel corner walls which interconnect the funnel lateral plane walls. The eight funnel walls are substantially longer in the axial direction than the cylindrical wall section (16′). The corner walls (18) and the lateral plane walls have approximately the same axial length (H≈H′). The eight funnel walls cooperate in avoiding clogging of the bulk material as it flows through the funnel.
