Abstract: The invention concerns a stamping film for the production of tamper-proof license plates and a license plate produced using a stamping film. The stamping film includes a carrier film and a transfer layer which is detachable from the carrier film and which can be fixed on a substrate of the license plate. Starting from the carrier film, the transfer layer includes a transparent release layer, an opaque decoration layer, a transparent protection layer, an optically variable layer, a reflection layer, a colored layer and an adhesive layer. The decoration layer has mutually spaced areal interruptions where the transparent protection layer adjoins the release layer. The adhesive layer is provided for fixing the transfer layer to the substrate of the license plate.

Abstract: The invention relates to a production method for a number plate for a motor vehicle, comprising the following steps: 1. Imprinting a carrier film (2) with individual signs (7) in a printing step, 2. Laminating the printed carrier film (2) on a stampable carrier plate (1) in a laminating step, and 3. Mechanical stamping of the carrier plate (1) laminated with printed carrier film (2) according to the contour (8) of the individual signs (7), which are produced in the printing step, in a stamping step.

Abstract: A method for producing a cast combination of cylindrical hollow profiles and for casting said combination into a cylinder block or crank housing of an internal combustion engine, wherein cylindrical hollow profiles consisting of a light-metal alloy and containing inlaid hard phases that have been manufactured by successive stages of spray compacting, hot extrusion and hot forming are arranged in a row, the distance between the axes of the hollow profiles corresponding to the cylinder bore center distance of the cylinder block and a light-metal alloy without inlaid hard phases is cast around said profiles. The cast combination is then positioned in a mould that forms the cylinder block and a light-metal material is cast around said combination.
