Abstract: There is described a method and an arrangement for the metrological detection of the differences in the visually perceived color impression between a multi-color patterned surface (10) of a reference and a multi-color patterned surface (12) of a test item. Concomitantly changes in the color statistics and in other color variation rates of the test item compared to a reference, and changes in the picture definition of the pattern of the test item compared to the reference, are determined by means of spatial sensors (24) provided with color capability, such as color picture cameras and displayed. According to the invention, a common variation rate for the visually perceived color variation of multi-color patterned surfaces with references is established by a combination of the two variations.

The device has a substantially planar base body, this base body comprising a plurality of openings and at least one closure plate, wherein the at least one closure plate is movably arranged via at least one securement element on the base body in such a way as to be able to close at least one of the openings.

Abstract: A method for the optical inspection of a transparent protective layer and a colored patterned surface which is at least partially covered by the transparent protective layer involves providing a source of illumination and an imaging sensor associated with the source of illumination and illuminating the protective layer with light emitted by the source of illumination in order to recognize defective places inside and beneath the transparent protective layer. The source of illumination emits light in the shortwaved range which is at least partially diffuse and the light striking the surface penetrates at least partially into the protective layer and is scattered at the defective places. Light scattered from the defective places is picked up by the imaging sensor and the defective places are recognized by the local increase in the intensity of the light picked up by the imaging sensor in the area of the defective places.

Abstract: A method is provided of manufacturing a bumper cover for a motor vehicle. The bumper cover includes at least one vehicle-specific deformation. The method includes the steps of injection molding a bumper cover blank using a single injection mold tool, and forming the at least one vehicle-specific deformation in the bumper cover blank to form the bumper cover.

Abstract: A radiator grille (10) for mounting in a motor vehicle radiator grille arrangement and a method of producing same, includes radiator grille having a substantially rigid frame (11) and at least one bar element (12) arranged within the frame (11). The bar element includes at least one end (12a) which, in the unassembled state of the radiator grille (10), is spaced from a portion (18) of the frame (11) and in the mounted state of the radiator grille (10) is forced into contact with the portion (18). The end (12a) of the bar element (12) and the portion (18) of the frame (11) being movable relative to one another as a result of the external application of force.

Abstract: A process for the production of tin-plated wires, in particular wires for electrical applications which are constituted of non-ferrous metals, for example, such as copper, having a diameter of 0.1 to 1.5 mm, and preferably of up to 1.0 mm, through the intermediary of a two-step tin-plating. The already finish-drawn wire is initially thinly hot tin-plated, thereafter cooled down, and finally galvanically tin-plated up to its finished coating thickness. Through the intermediary of this process, there can be uniformly tin-plated wires of the above-mentioned diameter, with a tin coating of 5 .mu.m, wherein tolerances can be attained with a typical value of .+-.1.5 .mu.m.
