Known large vibrating conveyors are not readily suitable as such for conveying bulk materials or small articles into or out of a liquid bath, because the liquid transmits the vibrations to other structural parts, for example a vessel for the liquid, as a result of the incompressibility of the liquid. In order to remedy this, the vibrating conveyor device according to the invention has a compressible space or chamber underneath the vibrating part which damps the vibrations, when suitably coordinated with the liquid bath. The space is preferably gas-filled and its damping properties can be varied by feeding additional gas through a line which can be shut off by a member, or by bleeding some of the filling through a further line which can likewise be shut off by a member.

The invention relates to a transparent display material having a conducting layer of a tin oxide and/or indium oxide composition which withstands electrochemical attacks without the need for elaborate measures. To this end, the invention provides that the conducting layer contains at least one metal of the Ib and/or eighth transition metal group with a content of from about 10.sup.-3 to 3% by weight, relative to tin oxide and/or indium oxide. The conducting layer according to the invention is particularly well suited for use in liquid-crystal displays.
