Patent number: 9481553Abstract: A system or method, for controlling at least two automated non-passing rail mounted gantry cranes, has, for each crane, a crane control unit for ensuring execution of at least one work order received by the respective crane from an external scheduling system, and may have a rescheduling unit which performs a rescheduling of the at least one work order based on an expected trajectory along the rail determined for each work order. The rescheduling can be achieved by splitting at least one of the work orders into at least two new work orders and by re-sequencing and re-allocating resulting work orders to reduce the number or duration of situations, where the expected trajectory of one crane blocks the expected trajectory of another crane and/or to reduce a workload imbalance between the cranes. The rescheduling unit operates in parallel with the crane control units, and dynamically updates these original work orders.Type: GrantFiled: March 4, 2013Date of Patent: November 1, 2016Assignee: ABB Schweiz AGInventors: Sleman Saliba, Bjoern Henrikson, Henrik Noren, Stefan Israelsson Tampe, Susanne Schmitt, Alessandro Zanarini, Kerstin Muxfeldt

Patent number: 8090470Abstract: A method for optimizing the position of a plurality of containers in a block, including at least one crane configured to move the containers is provided. A crane control unit (CCU) is provided in which the following steps are performed: identifying a selected container to be moved from a current position CP within a sub-section of said block to a new position NP within the sub-section; calculating a number of container moves required facilitating the move of the selected container in previous step; arranging the required number of container moves in a queue for each crane; and performing the container moves as arranged in the queue by controlling said at least one crane. Also provided is a computer program, a computer-readable medium encoded with the computer program, and a system for optimizing the position of a plurality of containers in a block.Type: GrantFiled: June 19, 2008Date of Patent: January 3, 2012Assignee: ABB Research Ltd.Inventors: Erik Lindeberg, Claes Heidenback, Bjorn Henriksson, Alf Isaksson, Stefan Israelsson Tampe

Patent number: 8049587Abstract: An air-core reactor with natural-air cooling of a winding includes first open spaces to let air flow through the winding in parallel with an axis of symmetry of the reactor and second open spaces crossing the first open spaces to let air flow through the winding angular to the axis of symmetry. A ventilation unit to produce a forced-air flow is arranged in such a way to the air-core reactor that a first part of the forced-air flow enters one of the first or second open spaces and at least one guiding element is arranged with respect to the crossing of the first and the second open spaces in such a way that the first part of the forced-air flow leaves and a second part of the forced-air flow enters the one of the first or second open spaces. A shielding element is arranged at another crossing of the first and the second open spaces so that substantially no air can leave or enter the one of the first or second open spaces.Type: GrantFiled: November 6, 2006Date of Patent: November 1, 2011Assignee: ABB Research Ltd.Inventors: Stefan Israelsson Tampe, Peter Löfgren, Piotr Login, Björn Jacobson

Patent number: 7669638Abstract: A control system for regulating the flow of liquid metal in a device for casting a metal. A detector measures a process variable. A control unit evaluates data from the detector. At least one process parameter is automatically varied in order to optimize casting conditions. The detector measures a characteristic of the meniscus at at least two points on the meniscus instantaneously throughout the casting process.Type: GrantFiled: November 28, 2003Date of Patent: March 2, 2010Assignee: ABB ABInventors: Sten Kollberg, Jan-Erik Eriksson, Carl-Fredrik Lindberg, Mats Molander, Peter Löfgren, Göte Tallbäck, Rebei Bel Fdhila, Bertil Samuelsson, Stefan Israelsson Tampe, Christina Wallin

Publication number: 20080044584Abstract: A device and a method for stabilizing an elongated metallic strip of a magnetic material when coating the strip with a metallic layer. The strip is transported from the bath in a direction of transport along a predetermined transport path. A wiping device for wiping off superfluous molten metal from the strip applies an air flow in a line across the strip, where the wiping device includes at least one pair of air-knives arranged with one air-knife on each side of the strip. An electromagnetic stabilizing device stabilizes the position of the strip with respect to the predetermined transport path. A sensor detects the position of the strip in relation to the predetermined transport path.Type: ApplicationFiled: June 23, 2005Publication date: February 21, 2008Applicant: ABB ABInventors: Jan-Erik Eriksson, Conny Svahn, Mats Molander, Carl-Fredrik Lindberg, Peter Lofgren, Stefan Israelsson Tampe, Bengt Rydholm
