Patent number: 10266374Abstract: The disclosure relates to a lift installation having a lift car which can be moved along a guide rail. The lift installation here comprises at least a first pair of rollers and a second pair of rollers. The guide rail runs between the two rollers of the first pair of rollers and between the two rollers of the second pair of rollers. The lift installation also has an apparatus for subjecting the lift car to a retaining force, wherein there is a horizontal offset between the point at which the retaining force takes effect and the center of gravity of the lift car, and therefore the lift car is subjected to a first torque.Type: GrantFiled: October 22, 2015Date of Patent: April 23, 2019Assignees: thyssenkrupp Elevator AG, thyssenkrupp AGInventors: Friedrich Löser, Markus Jetter

Patent number: 10173865Abstract: An example electromotive linear drive mechanism for moving walkways for conveying people or objects may comprise a long stator as an active primary part positioned along a direction of movement of a moving walkway, as well as a plurality of passive secondary parts that are movable with respect to the active primary part and are arranged with one another along the direction of movement. The long stator may have a plurality of successive long stator sections in the form of coil groups along the direction of movement. Each long stator section may have its own control device that is configured to move the secondary parts using control parameters stipulated for the respective long stator section. Further, example methods for operating the electromotive linear drive mechanism may involve predefining different movement profiles for the respective control devices for at least some of the long stator sections such that the secondary parts move along the long stator in a non-uniform manner.Type: GrantFiled: August 1, 2014Date of Patent: January 8, 2019Assignee: THYSSENKRUPP ELEVATOR AGInventors: Jürgen Frantzheld, Qinghua Zheng, Friedrich Löser

Patent number: 8297195Abstract: A method for operation of a magnetic levitation railway which contains vehicles with a plurality of supporting magnets (20a . . . 20j) and supporting runners (26) associated with them. In the event of a malfunction, the braking of the vehicle with the drive and braking systems switched off is brought about or assisted until a preselected destination stopping point is reached solely in that, even before the destination stopping point is reached, at least one of the supporting magnets (for example 20f, 20g) is switched off, and the magnetic levitation vehicle is placed on the track path (3) by means of the associated supporting runner (26), and is brought to rest at the destination stopping point by making use of the friction forces that occur as a result. A magnetic levitation vehicle is provided and operated in this way.Type: GrantFiled: November 26, 2007Date of Patent: October 30, 2012Assignee: ThyssenKrupp Transrapid GmbHInventors: Friedrich Löser, Qinghua Zheng

Patent number: 6857625Abstract: The invention relates to a spring carrier for the chassis of a motor vehicle. Said carrier is used to support a coil spring (1) which is braced between two spring plates (2, 3). At least one of said spring plates (2) can be axially adjusted by means of a drive unit comprising a gearbox and an electric motor. Preferably, at least one part of the piston rod (6) and/or the shock-absorber tube (5) of a shock-absorber or a suspension strut is arranged inside the coil spring (1). The aim of the invention is to develop one such spring carrier in such a way that the distance between the upper spring end and the vehicle body can be kept small in a cost-effective manner. To this end, the electric motor is embodied in the form of a ring motor having an external stator (15) and an internal rotor (16) which comprises a displacement nut on its inner side, said displacement nut axially displacing a spring plate carrier (21) connected to the spring plate (2) and externally embodied as a threaded spindle.Type: GrantFiled: December 15, 2001Date of Patent: February 22, 2005Assignee: ThyssenKrupp Automotive AGInventors: Friedrich Löser, Siegfried Ellmann

Patent number: 5053654Abstract: A device for driving a vehicle by magnetic levitation includes a synchronous long-stator motor, with a long stator winding extending along a track of the vehicle and subdivided into a plurality of discrete stator winding sections (3.11 to 3.19; 3.21 to 3.29). The vehicle which is movable on the track supports several fixedly mounted exciters cooperating with the stator winding sections. At least one section cable (17, 28) is arranged parallel to a portion of the track and each of its ends is connected to a power sub-station. The section cable has a plurality of consecutive tap points each being connectable via a switching device to an assigned stator winding section. The switching devices are activated when the vehicle runs over the corresponding winding section.Type: GrantFiled: May 21, 1990Date of Patent: October 1, 1991Assignee: Thyssen Industrie AGInventors: Friedemann Augsburger, Gerhard Holzinger, Friedrich Loser, Hermann Von Kuepach

Patent number: 4320395Abstract: A television-type system for displaying characters of an alpha-numeric test n a horizontal line moving across the face of a TV monitor includes pulse-generator-fed frequency dividers emitting pulse sequences of which three are transmitted via viewer-operated selectors for forming two frequencies f.sub.L and f.sub.Z applied to shift registers of a character generator to determine character height and width and another frequency f.sub.G applied to the stepping input of a delay-increment counter to determine character speed. In response to character codes transmitted from an input unit via a read/write memory, the character generator emits binary signals combinable with horizontal and vertical sync pulses into a video signal fed to the monitor. The counter is reset upon every horizontal sync pulse to have a modulus n equal to the contents of a total-delay counter stepped by the vertical sync pulses and reset after N of the same by a divder calculating the quotient N=T.sub.Z /T.sub.Type: GrantFiled: March 10, 1980Date of Patent: March 16, 1982Assignee: Kernforschungsanlage Julich Gesellschaft mit beschrankter HaftungInventors: Ralf Meissen, Friedrich Loser, Joachim Berwix, Christof Krischer
