    摘要： In a known method, a SiO2 slip layer is applied to a basic quartz glass body by means of spraying on an SiO2 slip, the slip layer is dried and sintered to form an SiO2-containing functional layer. In order to permit the reproducible production of a functional quartz glass layer, even in the case of surfaces that are curved or inclined with respect to the vertical, having high layer thicknesses which satisfy high requirements on the layer homogeneity, the invention proposes that the slip contain the following components in a dispersion liquid: splintery, amorphous SiO2 granules having a gain size distribution having a D50 value in the range of 3 μm to 30 μm and having a proportion by weight of at least 10% by weight, based on the total solids content; spherical, amorphous SiO2 particles having a particle size distribution having a D50 value in the range of 1 μm to 50 μm and having a proportion by weight of at least 30% by weight, based on the total solids content; SiO2 nano particles having particle sizes of less than 100 nm and having a proportion by weight between 0.2% and 10% by weight, based on the total solids content; and a non-ionic, alkali-free surfactant having a proportion in the range of 0.005 to 0.5%, based on the volume of the dispersion liquid.

    摘要： Common solar radiation receivers are equipped with a chamber for transmission of an operating gas which is directed along to an absorber for solar radiation for thermal absorption. The absorber has a dome-shaped entry window made of quartz glass, wherein the inner side facing the absorber assumes a nominal interior temperature Ti of at least 950° C. during proper use, preferably at least 1000° C., whereas the outer side facing away from the absorber is exposed to the environment and subject to risk of devitrification. The invention relates to modifying the known solar radiation receiver so that a high absorber temperature can be set and thus a high efficiency of the solar thermal heating is enabled, without increasing the risk of devitrification in the region of the outer side of the entry window.

    摘要： a method and to an apparatus for producing optical glass elements, in particular for producing what is referred to as low-cost optics for focusing light onto small areas, for example, for photovoltaic applications or optical couplers. The method for producing the optical glass elements includes: providing a glass rod having a selected cross-section, heating the glass rod such that it can be deformed in at least some sections, molding at least one optical glass element from the deformable section using a molding tool, separating the optical glass element from the glass rod at the connection, arranging a plurality of separated optical glass elements to form a group, and grinding and/or polishing at least one section of the separating surfaces of the grouped optical glass elements. The invention makes it possible to produce optical glass elements that meet low quality requirements in high quantities and with high output at low cost.

    摘要： A high-voltage electronic tube includes a housing enclosing a vacuumized space. The housing has a cylindrical metal jacket and an annular insulating disc connected vacuumtight to an inner face of the jacket. An electrode support passes through a central opening of the annular insulating disc and is connected vacuumtight to the annular insulating disc. The electrode support positions an electrode in the vacuumized space. A metal sleeve divides the annular insulating disc into two separate annular disc parts arranged concentrically to the tube axis. The metal sleeve is connected vacuumtight to the annular disc parts.
