Abstract: In a method for operating a system, which has a plurality of sensors (21, 22, 23), the sensors (21, 22, 23) provide first sensor data (11) to a primary process (31). Furthermore, the sensors (21, 22, 23) provide second sensor data (12). At least a part of the first sensor data (11) and the second sensor data (12) is subjected to an analysis (13). A result (16) of the analysis (13) is used in at least one secondary process (33) of the primary process (31).

Abstract: The at least one value is respectively determined from at least one measured value of the sensors (20-29) in a method for determining at least one physical value in a space (10) in which several sensors (20-29) are arranged which are set up to measurer the at least one value, for several positions (30) in the space (10) where there is no sensor (20-29). A system which is set up in order to determine the at least one physical value in the space (10) has several sensors (20-29) which are arranged in the space (10). Furthermore, it has a database, in which information about the space (10) is stored, and a computer which is set up in order to determine the at least one value by means of the method.

Abstract: A process for manufacturing a panel light-guiding element, including the step of rolling a metal body of one of aluminum and an aluminum alloy in at least one pass between at least two rolls to form a rolled product having at least one structured surface as a light guiding structure having a rib pattern of height h and a tooth-like cross-section. The tooth-like cross-section have a periodic structure of rows of triangles. The triangles have bases which follow each other, a first side of each of the triangles running at an angle &agr;, and a second side at an angle &bgr; from the base which has a length l. At least one of the rolls exhibits an embossed pattern that is structured to form the rib pattern in a rolling direction over a full length of the rolled product and is tooth-like in cross-section so that the angle &agr; is in a range of 5 to 60°, the angle &bgr; in a range of 10 to 90°, the length l in a range of 0.01 to 10 mm and the height h is 0.1 to 2 mm.

Abstract: A method is provided for producing a yarn from at least two individual yarn components having different physical characteristics so that the produced yarn has a desired visual effect. The method includes continuously supplying at least one yarn component in the form of a bundle of continuous filaments and individually treating the bundle of continuous filaments in a treating stage. The treated bundle of continuous filaments is then conveyed to a collective compacting stage. At least one other yarn component is supplied from a spinning beam or a bobbin directly to the collecting compacting stage and the bundle of continuous filaments and at least one other yarn component are compacted collectively in a collective compacting device.

Abstract: A light-guiding panel element arrangeable on a wall or a ceiling for lighting purposes. The light-guiding panel element including a walled metal body having at least one structured surface as a light deflecting structure with a ray of the pattern height h and a toothed-like cross-section. The tooth-like cross-section represents a period structure of rows of triangles. The triangles have bases that follow each other. A first side of each triangle runs at an angle &agr; and a second side at an angle &bgr; from the base which is length 1. The rib structure runs in a rolling direction, &agr; is an angle of 5 to 60°, &bgr; at an angle of 10 to 90°, a length l is 0.01 to 10 mm and the height h of the rib pattern is 0.1 to 2 mm. A line of contact of both sides of each triangle forms an edge with a radius r1 that is less than l/10.

Abstract: An apparatus for stuffer box crimping a synthetic filament thread includes a thread inlet duct for aspiring and guiding synthetic filament threads to a stuffer box. The apparatus includes a flow duct, the thread inlet duct preceding the flow duct, the flow duct and the thread inlet duct having a common longitudinal axis. The apparatus is provided with a nozzle having an outlet opening merging into the flow duct, for supplying a fluid under pressure. The two or more sets of nozzles may be arranged consecutively along the longitudinal axis of the thread inlet duct and the flow duct in a direction of thread transport.

Abstract: Method and apparatus for texturing thermoplastic threads. In starting the operation of the texturing device, one or several non-textured yarns can be drawn in more easily and more reliably via a drawing-in yarn guide which guides the at least one yarn for the purpose of drawing same into the feed channels of the texturizing nozzle and into the plug channels of the plug feed roller essentially parallel to these channels and at a predetermined distance from each other.

Abstract: A device for texturizing continuous filament threads including plates in a crimping part which have a prolongation at both ends thereof, with the prolongation being located centrically-symmetrically, however offset, relative to each other and have rounded end faces thus permitting reversing the plates upon wear of one end face thereof, thus increasing their service life.

Abstract: Threads made from thermoplastic materials are textured, in that they are heated by a delivery medium in a delivery channel and conveyed through an orifice into a stuffer box where they are stuffed to form a plug. In order to maintain plug formation constant, the orifice area is monitored in a sensory manner and the measured signals are used for monitoring purposes as a measured quantity in a control loop, in which the supply of damming back medium, the conveying away speed of the plug, the position of the stuffer box walls, or the supply of delivery medium are used as manipulated variables. The measuring signals produced by monitoring can be compared with thresholds to produce control signals corresponding to the comparison result for activating alarm, warning or stopping elements.
