    摘要: A casing for holding electronic components and the like, is provided on each of its side walls facing away from one another with two fastening lugs which project laterally therefrom and are each provided with an opening for the passage of a screw, and which are associated with casing side edges corresponding to one another. The openings for the passage of a screw which are provided in fastening lugs lying opposite one another and associated with the same side wall of the casing are in each case free from overlap, in their projection, with the fastening lug lying opposite. The arrangement of the fastening lugs makes possible the installation of the casing in both right-hand and left-hand drive vehicles without being mounted with mirror inversion. This provides advantages, for example, when there is restricted space to accommodate the cable leading out of the casing.

    摘要: The arrangement includes three casting lines arranged in front of a finishing train. The casting line in the middle is in alignment with the finishing train. The thin slabs severed from the cast strands are conveyed to the finishing train with two ferries and which are combined longitudinal/transverse/longitudinal conveying systems. The thin slabs are conveyed by placing the two ferries alternatingly in alignment with two adjacent casting lines.

    摘要: To make hot rolled steel strap from strap like cast starting material cast pieces can be first cut from the solidfying casting after the casting process is completed. Then these cast pieces are guided to and stored in an oven where they are brought to and maintained at the rolling temperature. The cast pieces are fed in succession into the rolling mill. Then the cast pieces are stored there at the rolling temperature until the rolling process begins. A number of cast pieces are produced as raw products in our invention and stored until the rolling of these individual cast pieces starts. the casting is continuous and occurs also during the rolling operation. Because of the intermediate storage provided by the oven significant differences can exist between the casting time and the rolling time. Assembly and maintenance of the rolling mill, e.g. roll changing, can be performed in a pause of the roll cycle which includes the rolling time. If necessary the two pauses of two roll cycles are placed immediately in succession. The cast pieces formed during this time are fed to the oven and stored there. An apparatus for performing this process is also described.

    摘要: A drag-chain conveyor has a trough-shaped elongated passage a bottom wall of which is formed with one or more openings each bounded by a circumferentially extending marginal wall portion of stepped cross-section. A discharge chute is provided for each opening and extends downwardly from the bottom wall. A closure plate is provided for each opening and each plate is movable between a position in which it is withdrawn from the respective opening and a position in which it is located and closes the opening. The closure plate has a circumferentially extending bevelled edge face which sealingly engages the wall portion bounding the respective opening when the closure plate is in its closing position. A mounting arrangement mounts the closure plate for movement between the positions thereof.

    摘要: The invention relates to a roll stand comprising a crown-variable-control (CVC) roll pair, preferably a CVC working roll pair and a back-up roll pair, which comprise a contact area (B cont) in which a horizontally active torque (M) acts that leads to a twisting of the rolls and thus to axial forces in the roll bearings. In order to keep the axial forces in the roll bearings as small as possible, the torque (M) is minimized by an appropriate CVC grinding.
