Publication number: 20230152074Abstract: A position of a movable part of a coordinate measuring machine (CMM) is determined repeatedly. A position value of the part is measured at a reference location. First and second acceleration values are measured at a first and second measuring location. The second measuring location is closer to a measuring sensor than the first measuring location and the first measuring location is closer to the reference location than the second measuring location. A target and/or actual state value is supplied to a model of the CMM. Estimators are modelled. The model is supplied with a position deviation based on the estimator of the position deviation and deviation based on the estimator of the deviation and the deviation of the measured first and second values. The position of the part is determined from the measured position value in relation to the reference location based on the estimator of the position deviation.Type: ApplicationFiled: November 15, 2022Publication date: May 18, 2023Inventors: Udo Gruber, Guenter Grupp

Patent number: 9334215Abstract: The invention relates to a process for separating acrolein from the process gas of a heterogeneously catalyzed oxidation of propene by means of atmospheric oxygen, wherein high boilers (including acrylic acid) are firstly separated off from the process gas by means of quenching and technical-grade acrolein having small proportions of low boilers is then obtained by means of absorption and subsequent distillation. Small amounts of a solvent by means of which, in particular, oligomers formed are separated off and the tendency for foam to be formed in the apparatuses or columns is reduced is added in the columns and heat exchangers in the work-up process. The solvent is, according to the invention, separated off and recycled in the form of an organic phase in-situ within the existing process.Type: GrantFiled: January 28, 2014Date of Patent: May 10, 2016Assignee: EVONIK DEGUSSA GmbHInventors: Wolfgang Boeck, Wolfgang Taugner, Udo Gruber

Patent number: 7219776Abstract: A friction disc, in particular a brake or clutch disc, includes carbon fiber-reinforced ceramic composite material with at least one top surface formed as a friction surface. At least part of the friction surface is formed of a different material, in particular of a carbon-containing material.
