Abstract: A hydrodynamic torque converter which has at least a hydrodynamic circuit including at least one pump wheel and one turbine wheel, wherein each of these wheels is provided with an outer shell to accept a set of vanes which form flow chambers, the inner edges of the vanes away from the outer shell being connected to an inner shell, which acts as part of an internal torus. At least the vanes of the turbine wheel have connecting elements both on the inner edges and on the outer edges, which connecting elements pass through openings in the shells to fasten the vanes to the shells, being provided for this purpose with a predetermined minimum overhang with respect to the edge of the associated vane, this minimum overhang making it possible for the connecting elements to be plastically deformed in such a way that they can grip the rear surfaces of the shells, i.e., the surfaces facing away from the vanes, and thus fasten the vanes to the shells.

Abstract: A bridging clutch is installed in a fluid medium-filled housing of a hydrodynamic coupling device located between a drive shaft and a transmission input shaft, the coupling device also containing a pump wheel and a turbine wheel. The bridging clutch is provided with a piston, which, when moved into a first axial position, brings at least one friction element into working connection with at least one friction surface, and when moved into a second axial position, at least partially releases this working connection, and with a torsional vibration damper, which is designed with at least one drive element and with at least one takeoff element, at least one of which has openings for circumferential springs and actuating areas for these springs. At least one of the takeoff elements acts a carrier element for the turbine wheel, which is held otherwise without radial support in the housing.

Abstract: A hydrodynamic torque converter which has a hydrodynamic circuit including at least one pump wheel and one turbine wheel, wherein each of these rotors is provided with an outer shell which accepts a set of vanes which form flow chambers, the inner edges of the vanes being connecting to an inner shell, which acts as part of an internal torus. For the sake of production, each of these vanes, before it is installed in the rotor in question, forms part of a vane plate, from which material is removed by industrial processing operations to create open areas in the plate. In addition, each vane has a curved zone and a flat zone, where the curved zone has at least one plane of curvature, which proceeds from a trailing flow edge of the vane toward the leading flow edge.

Abstract: A conveyor system for plates of metallic, magnetic or non-magnetic material is disclosed, consisting of a linear motor stator and a first nozzle plate which is arranged on the active side of the linear motor and a second nozzle plate arranged surface-parallel thereto while leaving a gap for the passage of the plates therebetween. By means of the nozzles of the nozzle plates, air cushions can be produced within the gap for the positioning of the plates. The magnetic fields produced by the linear motor can be employed to propel metal plates along the conveyor system.

Abstract: A four-way sheet metal pallet is disclosed. The pallet consists of rails of undulated cross-section which form at their outer edges closed conical hollow bodies, and of rail-supporting hollow bodies having recesses into which the rails can be fitted in form-locked and centering manner.

Abstract: A pallet is provided from a single profiled metal sheet which has the opposite edges folded inwardly several times along bend lines that extend transversely to profiled grooves of the sheet so as to form hollow girders having perpendicular supporting walls along the pallet edges. The sheet is provided along the bend lines and in accordance with the configuration of the profiled grooves with rows of recesses having associated slots to accommodate folding of the profiled sheet into the hollow girders.
