Patent number: 11242987Abstract: The present application provides a method of adjusting a feedwater mass flow rate to maintain a constant steam temperature in an evaporator section. The method may include the steps of determining a change in a number of operational parameters, predicting a change in steam temperature based on the number of operational parameters, combining the predicted changes in steam temperature, determining a feedforward signal based on dynamically offsetting the combined predicted changes in steam temperature, and changing the mass flow rate of feedwater based on the feedforward signal.Type: GrantFiled: November 19, 2018Date of Patent: February 8, 2022Assignee: General Electric Technology GmbHInventors: Petrus Johannes Koller, Alexander Taylor

Patent number: 11092332Abstract: The present application provides a once-through evaporator system. The once-through evaporator system may include a number of once-through evaporator sections with a distribution valve and a level sensor and a controller in communication with each distribution valve. The controller provides the distribution valve with a position set point and biases the position set point via a feedforward signal based on a fill level as determined by the level sensor in each of the once-through evaporator sections.Type: GrantFiled: November 16, 2018Date of Patent: August 17, 2021Assignee: General Electric Technology GmbHInventors: Petrus Johannes Koller, Rudolf Zinniker, Hans Ulrich Lenherr, Alexander Taylor, Stefan Lukas Gysel

Patent number: 8545199Abstract: The invention relates to a vane pump (1), in particular a regulatable oil pump for a lubricating system, with a pump housing (2) with at least one housing tank (6) and with a vane rotor (11) disposed in the housing tank (6) mounted so that it can be rotated by means of a drive shaft (10) in the pump housing (2) constituting an axis of rotation (23) which provides a mount for vanes (15) in approximately radially extending fitting slots (14). An adjusting ring (27) is provided enclosing the vane rotor (11) and circumferentially bounding pump cells (26) which, by means of a cylindrical internal wall surface (31), can be displaced between a concentric position with respect to the vane rotor (11) and an eccentric position relative thereto, to which pressured is applied by positioning torques caused by the medium pressure and a positioning mechanism (47) in order to regulate a pressure level.Type: GrantFiled: July 20, 2006Date of Patent: October 1, 2013Assignee: MIBA Sinter Holding GmbH & Co KGInventors: Johannes Koller, Franz Wimmer, Helmut Buchleitner, Helmut Pamminger, Michael Hiller
