    摘要: The coated noble metal element used in glass manufacture, such as a noble metal pipe, has an uncoated side that contacts a glass melt and an H2-impervious layer or an H2-impervious and O2-impervious layer, which is provided on a side opposite from the uncoated side. The H2-impervious layer or H2-impervious and O2-impervious layer is heat-resistant and is liquid or solid. In one process for providing the layer on the noble metal element an empty space between the noble metal element and a ceramic insulating jacket is filled with a coating material, and then the coating material is melted so that it wets a surface of the noble metal element. The coating material can include glass cullet, crushed glass or glass powder or is a mixture of crushed glass and ground ceramic material.

    摘要: The present invention relates to a method and apparatus for continuously manufacturing calibrated round or profiled glass tubes having a predetermined inner profile. In the method molten glass emerges from an outlet opening of a melt feed. The molten glass is drawn over a shaping body so as to form a hollow drawing bulb. According to the invention, the drawing bulb is drawn over a profile forming body positioned downstream of the shaping body so that inner circumferential surfaces of the drawing bulb are deformed whilst abutting against outer surfaces of the profile forming body to form the predetermined inner profile. According to the invention the distance between the shaping body and the profile forming body can be changed for varying the wall thickness of the glass tube.

    摘要: Methods of an apparatus for producing profiled glass tubing utilizing the Danner process comprise flowing the molten glass over profiled blowpipe heads which are "super-profiled" in that the angles of ridges and grooves are more acute than the ridges and grooves resulting in the glass tubing. The particular profiles of the glass tubing are controlled by selecting the necessary drawing speed, viscosity of the glass, internal air pressure at the blowpipe head and throughput rate of the glass melt.
