Patent number: 8530804Abstract: A method and a device for the continuous production of glass and glass ceramic products from a glass melt is provided, which simplifies the changing between two kinds of glass. The device includes a melting crucible and an induction coil, which preferably extends around the melting crucible in order to heat a glass melt by means of an induction field generated by the induction coil. The wall elements, which form the side wall of the crucible, have cooling channels, through which a cooling fluid can be conducted, so that the glass melt solidifies on the side wall and forms a skull layer. The interior side of the wall elements is formed at least in part by an aluminum nitride-containing ceramic.Type: GrantFiled: July 12, 2010Date of Patent: September 10, 2013Assignee: Schott AGInventors: Uwe Kolberg, Sybill Nuettgens, Thomas Kirsch, Andreas Gross, Ernst-Walter Schaefer

Publication number: 20130084642Abstract: The invention relates to a method for calibrating and/or adjusting an analytical device for chemical substances. A predetermined concentration of a chemical substance in a reference liquid is measured by mixing the reference liquid with a reagent for producing a color change, followed by irradiating with light of a predetermined wavelength. Based on the absorption of the light by the reference liquid, a concentration is determined, which is compared with the predetermined concentration of the reference liquid. In the case of which a calibrating and/or adjusting associated with the measurement process is possible without long interruptions of the measurement process, the predetermined concentration of the reference liquid is gained by mixing at least two standard, which contain different concentrations of the chemical substance.Type: ApplicationFiled: September 12, 2012Publication date: April 4, 2013Applicant: Endress + Hauser Conducta Gesellschaft fur Mess- und Regeltechnik mbH + Co.

Publication number: 20110083557Abstract: A method for removing chloride from samples containing volatile organic carbon, wherein a chloride containing sample is mixed with a difficultly volatile acid, wherein hydrochloric acid gas arises, which is present in dissolved form in a sample-acid mixture and then the hydrochloric acid gas is purged by a carrier gas from the sample-acid mixture, wherein the hydrochloric acid gas is removed from the carrier gas following the purging and the carrier gas is fed back to the sample-acid mixture. In order during the hydrochloric acid purging largely to suppress the driving out of easily volatile organic compounds, the sample-acid mixture has a temperature of approximately 3° C. to 30° C., wherein, following the purging from the sample-acid mixture, the hydrochloric acid gas is removed from the carrier gas by absorption with water.Type: ApplicationFiled: September 30, 2010Publication date: April 14, 2011Applicant: Endress + Hauser Conducta Gesellschaft für Mess- und Regeltechnik mbH + Co.

Publication number: 20070157774Abstract: Tool head as seat and drive for the rotary motion of a tool to be bilaterally supported in the tool head. Near its ends, the tool has centering faces which fit into rotatably developed seat bushings in the tool head. One of said seat bushings is arranged in a drive carriage and the other in a counter-bearing, in alignment with each other. The counter-bearing is part of a counter-bearing carriage which can be displaced far enough on the drive carriages to seat the tool so that the tool, which is located between the carriages, is held with the centering faces in the bushings and a pre-adjusted axial force is present. A rotary drive motor is connected to the tool via a tool spindle supported in the drive carriage and a positive clutch.
