20100227753 | OPTICAL GLASS, METHOD OF MAKING THE OPTICAL GLASS, OPTICAL ELEMENTS MADE WITH THE OPTICAL GLASS AND USES THEREOF - The lead- and arsenic-free optical glass has a refractive index nd of 1.55≦nd≦1.64, an Abbe number νd of 42≦νd≦65, and a low transition temperature Tg≦460° C., good producibility and processability, and crystallization stability. The optical glass has a composition within the following range, in wt. % based on oxide content: | 09-09-2010 |
20100242543 | METHOD AND SYSTEM FOR PRODUCING GLASS, IN WHICH CHEMICAL REDUCTION OF GLASS COMPONENTS IS AVOIDED - In the apparatus for producing glass reduction of reduction-sensitive components in the glass melt is reduced or preferably is prevented during the melting and/or fining processes by introducing an oxidizing agent into the glass melt. The apparatus has a melt crucible, a fining vessel, and a device for conducting oxygen and/or ozone into the glass melt in the melt crucible and/or fining vessel, in order to suppress reduction of reduction-sensitive components of the glass melt. A preferred embodiment of the apparatus has a metallic skull crucible, which includes the melt crucible and/or the fining vessel. The apparatus preferably includes a homogenization unit connected to the fining vessel to receive glass melt from the fining vessel in order to further process the glass melt after refining. | 09-30-2010 |
20100288351 | THIN-FILM SOLAR CELL - The thin-film solar cell includes at least one Na | 11-18-2010 |
20100288361 | THIN-FILM SOLAR CELL AND PROCESS FOR PRODUCING A THIN-FILM SOLAR CELL - The thin-film solar cell includes at least one Na | 11-18-2010 |
20100323874 | LEAD-CONTAINING SPACE GLASS, ITS PRODUCTION AND ITS USE - The optical glasses have increased refractive indices and are useful for making space-saving and light-weight imaging optics with lenses of different glass types for use in different objects travelling in space. The optical glasses are suitable for production of optics having low total weight, which is decisive for space applications. These space glasses have high UV- and VIS-transmittance in a range of between 300 and 800 nm and high stability of transmittance over a period of years, because their aging has been greatly limited. | 12-23-2010 |
