Abstract: In order to provide a method which can produce red glass vessels and which is attended by low cost in respect of the raw materials/starting materials and also in respect of control of process parameters, an appropriate method for producing red glass vessels is proposed in which a colourless molten glass composition containing at most 3% by mass of tin oxide and at most 3% by mass of copper oxide is produced, where the resultant colourless molten glass composition is refined under neutral conditions with sodium sulphate and/or calcium sulphate and with a carbon-containing reducing agent with a molar carbon/sulphate ratio of from 0.5 to 5, where glass vessels are moulded from said refined glass composition, and where the glass vessels are cooled to a temperature of below 520 degrees C. to 580 degrees C.

Abstract: In a method for producing and refining a glass melt in a glass melting end, a mixture is fed to the glass melting end, the mixture is transformed into the glass melt under the action of heat in the glass melting end, and fuel is combusted with air and/or oxygen being supplied above the glass melt in order to generate heat in the glass melting end. In order to improve the thermal conditions inside the glass melting end, according to the invention wood dust is introduced as fuel into the combustion space present above the glass melt in the glass melting end and is combusted there, with air and/or oxygen being supplied.

Abstract: The invention relates to a thermally sprayed surface layer of titanium (21) on a non-metal substrate (3) of an orthopedic implant (1). In accordance with the invention, the thermally sprayed surface layer (2) includes an X-ray sensitive admixture with respect to the titanium (21), wherein the X-ray sensitive admixture includes a biocompatible indicator metal (4) between 0.01 at % and 20 at %, wherein the atomic weight of the biocompatible indicator metal (4) is larger than the atomic weight of titanium (21). Furthermore, the invention relates to an orthopedic implant (1) with a thermally sprayed surface layer (2).

Abstract: Method for producing cutting tools provides a first hard material coating on a first region of a tool base body containing at least one cutting edge, using a plasma vacuum coating process. A second hard material coating is provided on a second region which is adjacent the first, also via plasma vacuum coating process. Hard material for the coatings is a carbide, oxide, oxicarbide, nitride, nitrocarbide, oxinitride or nitrooxicarbide of at least two of Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Al. The first coating has a content of at least two of the metal elements which is at most 2 at % different from the content of the two metal elements in the second coating if the tool is for higher adhesive strength than hardness. The first coating has a content of the two metal elements that is different from the content of the two metal elements of the second coating by more than 2 at % if the tool is for higher hardness than high adhesive strength.

Abstract: A set of machining tools containing at least two separate tools is provided, one of which is tailored for a certain type of application and the other tailored for another application or use. The first tool is particularly adapted for applications having service requirements where the coating on the basic body of the tool must have high adhesive strength, but need not have high hardness, and the second tool is for service requirements of high hardness for the hard material coating, where the adhesive strength is not important.
