Abstract: A method is disclosed for determining a mechanical-technological characteristic variable of ferromagnetic metals, preferably ferromagnetic steels, and in particular fine-grained steels, which are used in pipelines. A magnetization apparatus, which has at least one permanent magnet or solenoid, magnetizes the metal which is to be determined, and a sensor apparatus comprising a transmission coil generates a magnetic field which interacts with the magnetic field which is generated by the magnetization apparatus in the metal, and which generates an eddy current. The eddy current is generated in the magnetically at least substantially saturated metal, and the eddy current is measured by an eddy current sensor of the sensor apparatus.

Abstract: A plate for use with a transport-and-storage unit includes a plate-shaped body having a stable form for receiving a layer formed from packages or groups of packages. The body has a planer upper side and a planar underside opposite each other. A holder is provided on at least part of the underside's perimeter.

Abstract: A vacuum pump generates a vacuum, in a suction device, with an air intake device and an air exhaust device, as well as a motor for driving the vacuum pump. The air exhaust device is provided with a discharge valve. The exhaust air is downstream of the discharge valve divided into two partial flows that are respectively associated with a pipe section.

Abstract: An applicator roll (1) is described for a labeling apparatus for paying out and applying self-adhesive labels, which with each operating cycle moves one self-adhesive label into a dispensing position underneath an applicator roll. Depending on the printing mechanism used in the labeling apparatus, whether printing an even or an odd number of digits, it is advantageous to arranged a profiled ring (32) formed on a sleeve (31) of the applicator roll (1) in the center or off center. In addition, label formats of different widths require applicator rolls of different widths. These problems are solved in the applicator roll (1) described here in that its sleeve (31) supports two cylindrical jackets (34) on either side of the profiled ring (32). The cylindrical jackets (34) are axially displaceable on the sleeve (31) and can be releasably, positively locked in several positions against axial shifting, preferably by mutual engagement of an annular collar (38) and an annular groove (40).
