An ornamental sequin system including a selected visual adaptation provided in a visual plane of at least one sequin to form an ornamental sequin system surface of interlaced colors or images is set forth. A novel method is also set forth. The method includes the following steps: forming a sequin base material; and punching the sequin base material to form a plurality of sequins, the plurality of sequins containing both information required to form an ornamental arrangement and positional information, thereby adapting the plurality of sequins for application to a surface.

The test elements are provided that are adapted to detect at least one analyte in a sample. At least some of the test elements are provided with a defect marking which contains information about defectiveness of the test elements. The test elements include at least one radiation-sensitive material. The test elements are exposed to at least one radiation, the radiation being adapted to induce marking in the form of at least one optically detectable change in the radiation-sensitive material.

The invention refers to a method and apparatus for CVD coating and to a coated body. To improve the mechanical properties of the structure and surface of the body and to make the method and apparatus as simple and cost-effective as possible, it is suggested in the method, in which a layer is deposited on a substrate in a carbon-containing gas atmosphere: that the process parameters be varied during the coating period in such a way that during the coating period a first operating mode and a second operating mode are repeatedly alternated, wherein in the first operating mode a higher carbon over-saturation of the gas atmosphere occurs near the substrate, and in the second operating mode a lower carbon over-saturation of the gas atmosphere occurs near the substrate. In this way, a body can be produced with a substrate and at least one layer deposited on the surface of the substrate, wherein the layer consists of nano-crystalline diamond.

The production of pouch-shaped or pot-shaped parts is undertaken in two steps. In the first step, a film located above a die is pressed by a stamp into a cavity that reproduces the part and is subsequently pressed apart in the lower region of the cavity by deformation of the stamp in this region. The device has a rubber-like stamp that expands out on all sides once it has reached the bottom wall of the cavity and causes the film to conform to the shape of the cavity. The stamp is preferably designed in two parts, wherein a stamp insert is guided within a stamp guide and the stamp insert then has at least one deformable region. For removal of the formed film, provision is made that the die can be swung open.

The present invention relates to a component, for example a tool, coated with a hard material, in particular diamond, a process for its production and a device for carrying out the process. The process for the production of the component coated with the hard material comprises the steps of: a) introducing a fine-grained cemented carbide or carbide-containing cement substrate into a vacuum system with a heating device and at least one gas feed connection; b) removing carbon from the carbides of a surface layer of the substrate at a substrate temperature in the region of about 900° C. to about 1400° C. and in an oxygen-containing atmosphere; c) introducing carbon into the surface layer of the substrate at a substrate temperature in the region of about 900° C. to about 1400° C. and in a carbon-containing atmosphere; and d) coating the substrate with the hard material.
