Publication number: 20050107215Abstract: A method for automatically adjusting slip in an automatic friction clutch arranged between an engine and a gearbox of a motor vehicle. The clutch has a clutch-adjusting positioning drive which adjusts the clutch to a position which is defined by a position set-point signal. The clutch input speed and the clutch output speed are detected using speed sensors and a position set-point signal is produced according to the difference of the speeds (slip speed). The slip speed is equal to a predefined set slip value and is used as a control variable for the transmitted clutch torque. An engine torque is used as a control variable for the clutch instead of the clutch torque or as a complement thereto.Type: ApplicationFiled: February 11, 2004Publication date: May 19, 2005Applicant: LUK LAMELLEN UND KUPPLUNGSBAU BETEILIGUNGS KGInventors: Olaf Werner, Thorsten Krause, Klaus Kuepper

Patent number: 6689230Abstract: A method of cooling on a cooling bed hot-rolled steel sections from rolling heat, wherein the sections, particularly rails, have section parts of different masses arranged at a distance from each other over the cross-section of the section, and an apparatus for carrying out the method. Initially, the heat quantities to be proportionally removed from the different section parts in dependence on their mass and temperature and the quantity of cooling medium required for this removal are determined and computed by using measuring equipment together with a computing unit by means of a computer program. Subsequently, cooling of the different section parts or their masses is carried out in a controlled manner in such a way that the section parts reach with as little time delay as possible the transformation line Ar3/Ar1 during the decomposition of the gamma-mixed crystal into ferrite and/or pearlite while releasing the transformation heat.Type: GrantFiled: September 13, 2000Date of Patent: February 10, 2004Assignee: SMS Schloemann-Siemag AktiengesellschaftInventors: Meinert Meyer, Klaus Küppers, Manfred Albedyhl, Bruno Böhmer
