Abstract: An optical plug connector device includes at least one lens array and at least one fiber holder, which is designed to position end regions of a plurality of optical fibers relative to the lens array, and which has at least one first fiber holding element wherein the fiber holder comprises at least one second fiber holding element having a higher manufacturing precision than the first fiber holding element.

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.

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.

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.

Abstract: A plug for light wave conductors or photo-conductors with a plug housing into a rear end of which a photo-conductor bundle with at least two photo-conductor fibers is introduced, and from an oppositely lying front end of which there emerge ferrules, into which, in each case, one of the photo-conductor fibers is introduced. The ferrules are supported in a ferrule housing which is installed in a plug housing correspondingly formed for the reception of the ferrule housing. The ferrules are movable, spring-loaded in their axial direction, in which the plug is intended for being plugged together with a coupling housing that receives this plug. The ferrule housing comprises a core housing and a core interior housing, which are designed for the reception of two ferrules. The ferrules are supported in the core housing. Front ends of the ferrules extend forward through the core housing and rear ends of the ferrules extend into the core interior housing.
