Abstract: A regulatorless oscillating system for a watch includes a spiral balance spring having an inner fastening point attached to a collet which can be connected to a balance staff, an outer fastening point connected to a balance spring stud, and an end region adjacent to the stud. The end region is held so that it can be adjustably positioned in a plane which is perpendicular to the balance staff, thereby decentralizing the balance spring in order to compensate for isochronism errors.

Abstract: The device for drying laundry 1 by means of a current of air comprises a drum 2 to accommodate the laundry 1 and a ducting system 3,4,5, to direct said current of air. The ducting system 3, 4, 5 has a section 3 arranged downstream of the drum 2, in which the current of air is directed downwards and in which is arranged a filter 6 to capture lint 7 from the current of air. A scraper 8,9 is assigned to the filter 8, in order to scrape off the lint 7. This filter 8 is a channel 6 arranged in an approximately horizontal manner and in the form of an inverted arch, and the scraper 8, 9 has a foil 8 resting on the filter 6 in a sprung manner and curved in accordance with the shape of the channel 6. The invention enables the automatic clearance of captured lint 7 from the filter 6.

Abstract: A method for operating a technical facility includes an expert system for diagnosing the operating state of the technical facility. Once the expert system has identified a malfunction of the technical facility, the expert knowledge available in the knowledge base of the expert system is also used parallel to the establishment of a diagnosis to calculate a regulatory intervention in the technical facility with the purpose of automatically eliminating a malfunction.

Abstract: The invention concerns a method for operating a technical facility (2) comprising an expert system (1) for diagnosing (9) the operating state of the technical facility (2). Once the expert system (1) has identified a malfunction of the technical facility (2), the expert knowledge available in the knowledge base (WB) of the expert system (1) is also used parallel to the establishment of a diagnosis (9) to calculate a regulatory intervention (u) in the technical facility (2) with the purpose of automatically eliminating a malfunction.
