Abstract: The invention relates to a method for carrying out chemical and physical methods, in particular for producing organic pigments or the preparations based thereon. The inventive method consists in injecting at least two liquids or suspensions in a vertex chamber, without using carrying gas, with the aid of two end pipes which are not coaxially oriented.

Abstract: The invention is directed to cleaning of micro- and mini-reactors for controlled process management and for avoiding blockages on carrying out chemical reactions and physical processes. The invention is characterized in that the micro- or mini-reactor is cleaned by means of a controlled pressure increase with a subsequent sudden release or with a gas pressure surge in a cyclical manner or using a controller. Wall deposits formed from solid material(s) involved in the chemical synthesis or the physical process are thus almost completely removed such that, after the cleaning procedure, the initial operating pressure can be set in the micro- or mini-reactor. A blockage of the micro- or mini-reactor can thus be avoided and the transferring of said production method to the production scale with micro- or mini-reactors is possible for the first time.

Abstract: A telecommunication device (1) is provided for identification of a caller number of a calling party. The telecommunication device (1) includes a caller identification circuit (5), a memory (10) for storing numbers of callers and a comparator (15) for comparing numbers of calling parties with the caller numbers stored in the memory. The telecommunication device supplies data of the calling party to a display device when the caller number of a calling party agrees with a caller number stored in memory. A truncation of the caller number of the calling party at its end by a predetermined number of digits occurs when there is no agreement between the caller number of the calling party and any of the numbers stored in the memory and a comparison of the branch exchange main numbers stored in the memory with the shortened caller number occurs.
