Abstract: A transport system for spinning bobbins and bobbin tubes comprises a transport path with two essentially vertical sections and an essentially horizontal section connected therebetween. The spinning bobbins and bobbin tubes are transported on pallets whose foot portion comprises an element consisting of magnetizable material. A conveyor belt runs along the transport path at the back side of which belt stationarily arranged permanent magnets are arranged to exert magnetic forces to hold the pallets on the conveyor belt.

Abstract: A method and an arrangement for optically representing information on a transparent projection surface using several projection modules and using through-light projection. The method and arrangement are both cost effective and ensures that an observer viewing even a large display of information is provided with a bright, contrast, homogeneous image. Each projection module is formed of a light source with a divergent beam radiating through a controllable light valve and a projection surface arranged behind it. The distance between the light valve and the projection surface is chosen in such a way that the image parts projected by adjacent modules border gaplessly to each other on the projection surface.
