Abstract: A method for continuously producing a strip-shaped metallic workpiece may involve introducing a molten mass into a casting region, solidifying the molten mass introduced into the casting region at least partially, and conveying the at least partially solidified molten mass out of the casting region. Hollow bodies may be added to the molten mass and encapsulated into the workpiece. Further, an apparatus for continuously producing a strip-shaped metallic workpiece may include a casting region into which a molten mass can be introduced and in which the molten mass introduced can solidify at least partially. The apparatus may also include a conveying device for conveying the molten mass out of the casting region, as well as a metering apparatus for adding hollow bodies to the molten mass.

Abstract: Methods for producing a rotationally symmetrical, hollow metallic workpiece may involve rotating a casting mould about a rotation axis and introducing a melt into the casting mould. The melt may be thrown towards an inner contour of the casting mould by centrifugal forces, and hollow bodies may be added to the melt. Furthermore, a device for producing a rotationally symmetrical, hollow metallic workpiece may include a casting mould that is rotatable about a rotation axis, a feeder device for introducing a melt into the casting mould such that the melt is thrown towards an inner contour of the casting mould by the effect of a centrifugal force, and a metering device for adding hollow bodies to the melt.

Abstract: A connector is disclosed for providing a positive and/or a non-positive connection between at least two connecting partners. The connector or connecting means has at least one first region which engages with the first connecting partner by way of a positive and/or a non-positive connection, and at least one second region is provided which engages with the at least second connecting partner by way of a positive and/or a non-positive connection. The connecting means provides a positive and/or non-positive connection between at least two connecting partners in a simple and inexpensive manner and which meets high safety requirements. The second region of the connecting means has a region which is formed from an at least partially flat material made of an Fe alloy with shape memory characteristics and which, when activated, ensures the positive and/or non-positive connection with the second connecting partner by way of a change in shape.
