Title: Process for preparing asymmetrical imidazolium salts
Inventor: MAUDUIT MARC
IPC: C07D233/58
Filed: 2013-12-11
Abstract: The invention relates to a process for preparing an asymmetrical imidazolium salt of formula (1A), in which R1 is an aromatic group, R2 is chosen from a cyclic secondary aliphatic alkyl group and a heteroalkyl group, R3 and R4 are chosen, independently of one another, from the group consisting of hydrogen, a halide and an alkyl group, and A" is an anion. The process comprises a first substep of forming a reaction mixture by bringing one equivalent of an aniline into contact with one equivalent of a compound bearing an amine group, in the presence of at least four point five equivalents of a Brønsted acid. The process also comprises a second substep of forming a solution comprising one equivalent of a dicarbonyl, one equivalent of formaldehyde, and at least four point five equivalents of the Brønsted acid, and adding thereto the reaction mixture formed in the first substep. The mixture is left to stir for a predetermined time at a predetermined temperature. The intermediate asymmetrical imidazolium salt 1A is then isolated.

Abstract: A change in a surface of a wall is detected by transmitting a pulse of input ultrasonic vibrations into a proximal surface of the wall and then receiving ultrasonic vibrations from that proximal surface. The received ultrasonic vibrations are compared with a previously detected pulse of output ultrasonic vibrations that have been received from the proximal surface in order to identify, for example, a time of arrival of a current pulse of output ultrasonic vibrations. The time of arrival of this current pulse of output of ultrasonic vibrations may be used to detect a change in the surface of the wall, such as a change in the thickness of the wall. Other embodiments can detect a change in the roughness profile of the wall using changes in the received ultrasonic vibrations other than arrival time.

Title: Screw for use in an extruder, method for converting a screw and an extruder
Inventor: SZURGOT MATEUSZ
IPC: B29C48/58
Filed: 2016-05-09
Abstract: The invention concerns a screw for use in an extruder as well as an extruder with such a screw. In particular the invention concerns a screw for use in a twin screw extruder and a twin screw extruder. Screws customarily have a modular design. The modular construction of a screw results in a rod-shaped core, the so-called mandrel, and individual screw elements that are pushed onto the mandrel.  To transmit the high occurring torque, the elements are connected to the mandrel in a positive-locking manner and also axially braced. The invention proposes designing the mandrel to be notch-free. This leads to a significant increase in the service life of such a mandrel, and thus also of the screw being used.
