Tue invention relates to a device and a method for repairing a damaged spot (201) of a surface, in particular a glass pane (200) or a windscreen of a motor vehicle. A control unit controls an impingement of pressure profiles, whereby a processing head (101) is secured to the glass pane (200) and a repair means is introduced into the damaged spot (201).

Glass articles with coatings are disclosed herein. According to embodiments, a glass article may include a glass body comprising glass and having a first surface and a second surface opposite the first surface, wherein the first surface is an exterior surface of the glass body. A coating disposed on at least a portion of the exterior surface of the glass body. The coated glass article may have an effective throughput rate greater than or equal to 1.10×R.sub.T, wherein R.sub.T is the effective throughput rate of an uncoated glass article in units of parts per minute (ppm).

A wavelength-converting element includes a substrate and a wavelength-converting layer. The wavelength-converting layer is disposed on the substrate. The wavelength-converting layer includes a first inorganic binder and a wavelength-converting material. The wavelength-converting material is mixed with the first inorganic binder. The first inorganic binder includes a first alcohol-soluble inorganic binder or a first water-soluble inorganic binder. A projection apparatus using the wavelength-converting element and a manufacturing method of the wavelength-converting element are also provided.

The present invention relates to a coating apparatus also called coating tunnel or coating hood for applying a protective coating to hollow glass containers. In particular it relates to a coating apparatus also called coating tunnel or coating hood with air curtains for reducing the loss of the carrier gas comprising a coating compound for applying the protective coatings to glass containers. More particularly the present invention relates to a coating apparatus also called coating tunnel or coating hood with specific air curtains at the entry and the exit of the coating apparatus for reducing the loss of the carrier gas comprising a coating compound for applying the protective coatings to glass containers.

A hollow body includes a wall which at least partially surrounds an interior volume of the hollow body. The wall comprises a layer of glass comprising a first glass composition, comprises a base surface, and has a wall surface. The wall surface comprises at least one surface region, in which the base surface is at least partially superimposed by at least one elevated region, and at least one contact region, which extends along a contact range of a height of the hollow body. The at least one elevated region comprises a further glass composition. An exterior diameter of the hollow body has a maximum throughout the contact range. The at least one surface region is at least partially positioned in the at least one contact region.

Apparatus and method for treating a substrate, for example texturing a substrate. In some embodiments, a masking material is applied to a surface of the substrate in a predetermined pattern, the surface thereafter contacted with an etchant that removes the masking material. Contacting the surface with the etchant produces multiple co-located textures. In other embodiments, the masking step can be eliminated, and the etchant is applied in a predetermined pattern to produce multiple co-located textures. In still other embodiments, the substrate has a chemical composition, and the substrate is exposed to a leachant that leaches at least one constituent of the chemical composition to produce a substrate with a varying chemical composition at the substrate surface.

Coated glass or glass ceramic substrates having high temperature resistance, high strength, and a low coefficient of thermal expansion. The coating includes pores, is fluid-tight and suitable for coating a temperature-resistant, high-strength glass or glass ceramic substrate with a low coefficient of thermal expansion, and to a method for producing such a coated substrate.

A heat-resistant composition including: a binder resin including at least two of a silicone-modified polyester resin, a siloxane compound, or a silanol compound; a pigment including at least two of iron cobalt chromite black spinel (ICCB), copper chromite black spinel (CCB), iron chromite manganese (ICM), or carbon black; and a catalyst.

In a known method for producing a quartz glass component, a crystal formation layer containing a crystallization promoter is produced on a coating surface of a base body of quartz glass. Starting therefrom, to provide a method for producing a quartz glass component of improved thermal strength and long-term stability which displays a comparatively small deformation particularly also in the case of rapid heating-up processes, it is suggested according to one aspect that a porous crystal formation layer containing amorphous SiO.sub.2 particles is produced with a mean thickness in the range of 0.1 to 5 mm, and that a substance which contains cesium and/or rubidium is used as the crystallization promoter.
