  • Method for performing a differential thermal analysis
    Patent number: 9310259
    Abstract: 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.

  • Rotary piston pump and method for operating a rotary piston pump
    Patent number: 9028233
    Abstract: A rotary piston pump equipped with a motor having two counter-rotating rotary pistons. The two rotary pistons are housed in an oval pump housing. The two rotary pistons are arranged on a first output shaft and a second output shaft. The first output shaft and the second output shaft are driven and synchronized via at least one elastic element.

  • Contact Element For Rotary Piston Pump
    Publication number: 20130129555
    Abstract: The rotary piston pump includes two counter-rotating rotary pistons and an oval pump housing. Every rotary piston has a rotary piston vane and is provided with a contact element. The contact points of the flanks of the two rotary pistons in which the two rotary pistons form a friction pairing are provided with a contact element each. The interior of the oval pump housing is likewise provided with an exchangeable contact element.
