Patent number: 10088441Abstract: Method and thermal analysis device including a sample holder and at least one temperature detector which is assigned to the holder. The invention further relates to a production method for a temperature detector. A heat flow to be detected is conveyed to the temperature detector between a support surface and the sample holder, wherein the support surface and/or the sample holder include elevations or depressions forming contact points, which define a relevant heat flow zone assigned to the support surface. A thermocouple, which includes at least two elements made of different metals, a first metallic element A, with a higher expansion coefficient compared to a second metallic element B, is introduced in a precisely fitting manner into second metallic element B constituted as a hollow profile and the two elements A, B are heated in a first operational step and then cooled again in a second operational step.Type: GrantFiled: August 28, 2015Date of Patent: October 2, 2018Assignee: Netzsch-Gerätebau GmbHInventors: Thomas Denner, Juergen Blumm, Otto Max Schaefer, Markus Hollering, Matthias Gradl, Gunther Herr, Andre Nijmeh, Thilo Hilpert, Alexander Frenzl, Stefan Lauterbach, Andreas Strobel, Gabriele Kaiser, Stefan Schmoelzer, Markus Meyer, Stephan Knappe, Rolf Preuss, Michael Gebhardt, Elena Moukhina, Alexander Schindler

Patent number: 9816869Abstract: A method for evaluating a measurement result of a thermal analysis. A program-controlled computer unit is used to calculate at least one probability of the agreement of the measurement result with at least one dataset previously stored in the computer unit, wherein this calculation is based on a comparison of effect data previously extracted from a measurement curve of the thermal analysis with corresponding stored effect data of the dataset. The evaluation can advantageously include, an automatic recognition and classification of measurement curves and can be carried out in particular more efficiently, more economically and more quickly than previously, with at the same time a high quality of evaluation.Type: GrantFiled: July 11, 2014Date of Patent: November 14, 2017Assignee: Netzsch-Gerätebau GmbHInventors: Thomas Denner, Juergen Blumm, Otto Max Schaefer, Markus Hollering, Thilo Hilpert, Alexander Frenzl, Stefan Lauterbach, Andreas Strobel, Gabriele Kaiser, Stephan Knappe, Rolf Preuss, Michael Gebhardt, Elena Moukhina, Alexander Schindler, Matthias Gradl, Gunther Herr, André Nijmeh, Stefan Schmoelzer, Markus Meyer

Patent number: 9310259Abstract: A method for conducting a differential thermal analysis, in which a sample disposed in a temperable sample space is tempered according to an essentially linear temperature program extending from a start temperature to an end temperature, such that, from the result of a measurement of the sample temperature conducted during tempering at a number of measurement time points, a DTA signal is calculated as the difference between a measured sample temperature and a reference temperature calculated according to a temperature curve model. According to the invention, for every measurement time point, the relevant reference temperature is calculated by the following steps: (a) establish a time interval containing the relevant measurement time point; (b) calculate a non-linear adjustment function for the measured sample temperature curve in the time interval; and (c) calculate the reference temperature as a value of the adjustment function for the measurement time point.Type: GrantFiled: January 24, 2014Date of Patent: April 12, 2016Assignee: Netzsch-Gerätebau GmbHInventors: Thomas Denner, Juergen Blumm, Otto Max Schaefer, Markus Hollering, Thilo Hilpert, Alexander Frenzl, Stefan Lauterbach, Andreas Strobel, Rolf Preuss, Michael Gebhardt, Elena Moukhina, Alexander Schindler, Mathias Gradl, Gunter Herr, Stephan Knappe, Markus Meyer, Gabriele Kaiser, Andre Nijmeh

Patent number: 5647320Abstract: A method and device for assembling and setting the injection pump elements in which the control rod is pressed against an elastically compliant stop in the form of a pin, which engages one end of a longitudinal groove of the control rod. In this position of the control rod, the injection pump elements have an adjusting pin inserted into a recess of the control rod, which adjusting pin is connected by a control arm to the plunger of the injection pump element, and the injection pump element is rotated so that the control arm lies against a stop of the injection pump element. The injection pump element is then bolted in place in this position.By this method and device the control rod, during assembly, is intentionally set a short distance further than it is possible to move it in normal operation by the controller.Type: GrantFiled: June 13, 1995Date of Patent: July 15, 1997Assignee: Klockner-Humboldt-Deutz AGInventors: Rolf Preuss, Josef Vonnahme
