Abstract: A process for automatically forming optical shuffles, which included providing a plurality of spools are provided, which are each formed from at least one fiber. The free ends of the fibers are led up to a winding device and fixed to the latter in such a way that the fibers can be wound onto it in one and the same winding direction and lying approximately parallel to one another. The sections of the fibers coming from the spool are combined with one another in groups to form ribbons. A first length section of each ribbon is unwound from the associated spool and wound onto the winding device (input side of the shuffle). After the length section has been unwound, the spools or fiber-guiding devices connected downstream of the spools are reorganized, so that, in a direction running transversely with respect to the unwinding direction, the outgoing fibers assume different positions relative to one another than before.

Abstract: A method of protecting a glass substrate, especially a display glass or a hard disk blank made from a glass or a glass-ceramic, from unacceptable surface damage and scratches, often leading to glass breakage, during processing and transport, is described. This protective method includes applying a removable protective coating made of at least one polymer layer, or at least one polyvinyl alcohol layer, to the glass substrates by spraying or rolling the polyvinyl alcohol or a polymer solution of the polymer to be applied in a polar organic solvent, onto the glass substrate, or dipping the substrate into it. Then when the substrate is ready for its end use, the protective coating is removed by washing in water or polar organic solution so that a residue does not remain on it. The glass substrates, protected in this manner have outstanding surface quality and improved hard disk blanks can be economically produced from them.

Abstract: Numerous applications for hollow glass bodies made from low melting glass material require an increase in the chemical resistance of the interior surface of the glass body. In order to avoid a disadvantageous de-alkalizing process the hollow glass body must be provided with an interior coating in a comparatively expensive prior art process. In an improved process according to the invention a glass tube acting as a semifinished product from which the hollow glass body is made is provided with an interior coating of oxide material, preferably SiO2, Al2O3, TiO2 or mixtures thereof, having a predetermined coating thickness according to the required chemical resistance or working conditions for forming the glass body and then the hollow glass body is made from the glass tube. The coating is advantageously provided by means of a PICVD process.

Abstract: The invention concerns a plasma CVD system (in particular a plasma pulse CVD system) with an array of microwave antennas. According to the invention, in order to improve the homogeneity of the layer, interference is prevented by controlling adjacent antennas in a chronologically offset manner. To that end, microcapsules are provided within the macrocapsules of the plasma pulse CVD process. Additionally, the uniformity of the layer deposition at the interfaces between adjacent modules can be optimized by radio-frequency excitation by means of suitable electrodes, magnetic fields or the configuration of the gas inlets. The surface coated in an operating cycle can thus be scaled as required.
