Patent number: 7799172Abstract: Apparatus for measuring tension or a tension alteration in a paper web. At least one measurement device includes a number of measurement bodies and a number of fluid supply devices, which are intended to apply a fluid pressure to the web. The fluid supply devices are so arranged as to subject the web to an essentially constant fluid pressure in order to provide a fluid cushion between the web and the measurement bodies. The measurement bodies are so arranged as to apply pressure to the web without making contact and are so arranged to be capable of displacement. The position of the measurement bodies in the normal direction of the web is altered depending upon variations in the constitution of the web. A method for measuring web tension and a machine including apparatus for measuring web tension are also disclosed.Type: GrantFiled: May 11, 2006Date of Patent: September 21, 2010Assignee: Webline Teknik ABInventor: Hans Högberg

Patent number: 5812563Abstract: A method and arrangement for testing circuit boards (60) by creating one or several reference patterns to be compared with a test pattern. The arrangement is provided with at least one measuring probe (50), which cooperates with the circuit board (60), for measuring at least one reference signal or test signal on a reference circuit board and a test circuit board (60) respectively. Further, the arrangement is provided with an analyzer (10,30), which cooperates with the measuring probe (50), to pass on the reference signal or the test signal, whereby the analyzer (10,30) first analyzes the reference signal or the test signal at one frequency and then transforms the reference signal or the test signal to a reference pattern and test pattern respectively. Furthermore, the arrangement is provided with at least one memory (20) which cooperates with said analyzer (10,30) to register said reference pattern or test pattern.Type: GrantFiled: June 27, 1997Date of Patent: September 22, 1998Assignee: Telefonaktiebolaget LM EricssonInventors: Mikael Hedlund, Hans Hogberg

Patent number: 5282583Abstract: A roll stand is designed to unwind a material web (60) to a printing machine (2) or other production machine from an unwinding roll (13) in the roll stand and for a stoppage-free automatic shifting to a new roll (5), when the unwinding roll has been emptied to the desired degree. In accordance with the invention, tension is detected in the material web, which while braked in the roll stand is fed into the production machine. Based on that detection, the power supplied to or from a power receiving or power supplying system is regulated in such a way that the tension in the material web, which is fed in to the production machine, is kept constant.Type: GrantFiled: October 26, 1992Date of Patent: February 1, 1994Assignee: Amal AktiebolagInventor: Hans Hogberg
