Patent number: 10126236Abstract: A method for detecting a contamination of a cuvette of a turbidimeter. The turbidimeter includes a light source which emits a light beam directed to a cuvette, a scattering light detector, and a diffuser with a body and an actuator. The actuator moves the body between a parking position and a test position where the body is between the measurement light source and the cuvette, thereby interferes with the light beam, and generates a diffuse test light entering the cuvette. The method includes activating the actuator to move the body from the parking position into the test position, activating the light source, measuring a test light intensity received by the scattering light detector, comparing the test light intensity measured with a reference light intensity, and generating a contamination signal if a difference between a reference light intensity and the test light intensity measured exceeds a first threshold value.Type: GrantFiled: November 8, 2017Date of Patent: November 13, 2018Assignee: HACH LANGE GMBHInventors: Manfred Battefeld, Michael Kussmann, Bas De Heij, Bernd Gassner, Frank Steinhauer, Hans-Joachim Kumpch, Axel Leyer, Michael Kueppers, Andreas Golitz, Andreas Mitreiter, Clemens Hanschke, Lothar Heidemanns

Patent number: 7897232Abstract: A wear-resistant and high temperature-resistant friction lining, in particular for a transport roller. The lining has a wear-resistant friction component embedded in a matrix and an additional component. The additional component is configured such that it is converted when exceeding a limit temperature while absorbing energy. Due to the endothermic reaction, a cooling effect takes place, which protects the friction lining. In particular, a so-called PBO fiber is used as the friction component.Type: GrantFiled: March 26, 2010Date of Patent: March 1, 2011Assignee: Luk Lamellen und Kupplungsbau Beteiligungs KGInventors: Tim-Florian Gerbing, Frank Steinhauer
