    摘要: According to the invention, the skull pot is provided with the following characteristics: a pot wall (1), a bottom (3) and an induction coil (9) which surrounds the pot wall (1) and by means of which high-frequency energy can be coupled into the contents of the pot. The pot wall (1) is made of a ring of metal pipes (1.1) which can be connected to a cooling medium. Slits are embodied between adjacent metal pipes (1.1). The metal pipes (1.1) are bent at a right angle at the upper ends thereof in such a way that said pipes extend towards the outside, when the pot wall (1) is viewed from above, and form a collar (2). The collar (2) is surrounded by an additional wall (upper wall 4). The upper edge of said wall is situated on a higher level than the collar (2) in such a way that the melt covers the collar (2) during operation.

    摘要: The invention relates to an optical hybrid lens. According to the invention, the lens consists of a substrate (1) that consists of a ceramic having a predetermined shape and at least another material (2), which covers a surface of the substrate (1) at least in certain sections in order to form a lens surface.Use of an optical ceramic as a material enables an additional degree of freedom for adjusting the imaging properties of the hybrid lens. The optical ceramic may have a high refractive index and a low dispersion. The other material can be a material that can be deformed or recast at temperatures that are low in comparison to those of the optical ceramic. In particular the other material can be a low-TG glass or a polymer. The other material is directly applied onto the substrate without a further surface finishing being necessarily required.Other aspects of the invention relate to an optical lens group, an optical image acquisition device, and a process for manufacturing a hybrid lens.

    摘要: The apparatus for reduced-pressure refining of a glass melt includes a refining bank formed so that a reduced pressure is generated by a glass flow in it. The refining bank has a component, which is made from a refractory metal or refractory alloy acting as glass-contact material. The refractory metal or alloy contains molybdenum, tungsten, tantalum, and/or hafnium. The device of the present invention includes a protective gas reservoir for a protective gas and an automatically operating valve connecting the reservoir with the refining bank so that an inner side of the component that would otherwise be exposed when a pressure rise or a falling glass melt column occurs is protected from oxidation by the protective gas. A process for using the device during refining of the glass melt is also part of the invention.
