Patent number: 10727843Abstract: A method for operating a wind turbine configured to supply electrical power to an electrical power supply network via a converter comprises measuring a phase angle and measuring a voltage of the electrical power supply network. A value of at least one parameter for a phase locked loop is determined depending on the measured voltage. The phase locked loop is used to determine a corrected phase angle depending on the measured phase angle and the voltage of the electrical power supply network. The corrected phase angle is input into the converter.Type: GrantFiled: January 18, 2019Date of Patent: July 28, 2020Assignees: Nordex Energy GmbH, Woodward Kempen GmbHInventors: Nils-Hendric Schall, Andreas Genius, Nils Hoffmann

Patent number: 10066599Abstract: A spar cap assembly is for a wind turbine rotor blade. The spar cap assembly has a spar cap reinforced with carbon fibers, comprising a lightning conductor, which is arranged so as to run along the spar cap, and at least one potential-equalizing element, which establishes an electrical connection between the spar cap and the lightning conductor. The carbon fibers of the spar cap, the lightning conductor and the at least one potential-equalizing element are embedded in a common polymer matrix and are configured as a prefabricated assembly for integration into a wind turbine rotor blade half-shell after the curing of the polymer matrix.Type: GrantFiled: April 7, 2015Date of Patent: September 4, 2018Assignee: Nordex Energy GmbHInventors: Nick Ohlerich, Hendrik Klein, Nils-Hendric Schall

Patent number: 7757606Abstract: An apparatus and method for registering a position of a component of a press is disclosed. The press having a plurality of components that can rotate about a central longitudinal axis, such as a main drive shaft and press cylinders, at least one of these components being assigned at least one position registering device, which registers the angular position of the respective component. The, or each, position registering device is formed as a magnetic rotary encoder.Type: GrantFiled: September 7, 2006Date of Patent: July 20, 2010Assignee: Man Roland Druckmaschinen AGInventors: Alfons Baintner, Nils-Hendric Schall, Klaus Liepert, Juergen Ziegler

Publication number: 20090288915Abstract: A method of operating a printing press, wherein lubricated components of the printing press are lubricated with lubricant during the operation of the printing press in such a way that lubricant is taken from a reservoir via a feed line and is supplied to the component or components to be lubricated and in that the lubricant is carried away from the respective component to be lubricated in a post-feed area. Metal particles in the lubricant in the area downstream of the respective component to be lubricated are detected by means of a sensor. The state of the respective component to be lubricated is determined on the basis of this measurement and, if need be, a repair or exchange of the respective component to be lubricated is initiated.Type: ApplicationFiled: May 20, 2009Publication date: November 26, 2009Applicant: manroland AGInventors: Stefan ALBRECHT, Nils-Hendric Schall, Markus Weng

Patent number: 5988063Abstract: A printing machine driven by one electric motor or by individual electric motors controllable by their own respective associated control systems. The control systems contain a subsystem observer or a total system observer, which obtains from the actual rotational angle speed (.omega..sub.ist) or the actual rotational angle (.phi..sub.ist) as well as from the electric-current or moment target value or actual value of the electric motor, an observed load torque (M.sub.LAST), which is supplied to the adjustment element as a component of the target moment (M.sub.soll). This signal can be applied via a differentiating filter or, in addition, via the proportional element, to the summing point. Alternatively to or in conjunction with the observer, a periodic compensation controller is provided in the control loop. The periodic compensation controller provides deviation-control for periodic disturbances and obtains, from the differential angular speed (.omega..sub.D), a component (M.sub.Type: GrantFiled: September 14, 1998Date of Patent: November 23, 1999Assignee: Man Roland Druckmaschinen AGInventors: Gunther Brandenburg, Stephen Geissenberger, Michael Schramm, Nils-Hendric Schall

Patent number: 5953991Abstract: A cylinder for a printing press is adjusted away from a printing stock web or an adjacent cylinder by rotation of an eccentric element. The change in position caused by the movement of the eccentric element is compensated by an additional rotating movement superposed on the rotating movement of the cylinder such that the outer surface of the cylinder has no relative velocity relative to the adjacent cylinder or the printing stock web. Compensation is carried out by a regulating circuit to which is supplied the actual rotational angle of the cylinder with respect to the eccentric element and the actual rotational angle of the eccentric element with respect to the side wall or an angular function derived therefrom.Type: GrantFiled: May 18, 1998Date of Patent: September 21, 1999Assignee: MAN Roland Druckmaschinen AGInventors: Stefan Geissenberger, Nils-Hendric Schall, Michael Schramm, Bernhard Feller, Michael Hess, Michael Dotzert
