Patent number: 8238999Abstract: In a method for display of at least one medical finding, at least one part of a body of a patient is shown on a display medium in a body view. A localization in the body of the patient is associated with each finding, and the localizations are marked at a point in the body view corresponding to the localization. The display medium is interactively operable, and a data set associated with the corresponding finding is displayed on the display medium by interaction with a marked localization.Type: GrantFiled: June 23, 2006Date of Patent: August 7, 2012Assignee: Siemens AktiengesellschaftInventors: Sultan Haider, Peter Kreisler, Klaus Küper, Horst Allgaier, legal representative, Matthias Philipp Lichy, Heinz-Peter Schlemmer

Patent number: 7999120Abstract: A process for continuously removing a target product X in the form of fine crystals from a liquid phase P comprising the target product X and constituents other than the target product X by cooling suspension crystallization in the secondary chamber, into which the liquid phase P flows continuously, of an indirect heat exchanger with simultaneous continuous flow of a coolant through the primary chamber of the indirect heat exchanger and continuous withdrawal of a crystal suspension S having a degree of crystallization Y from the secondary chamber, in which the degree of crystallization Y is adjusted on the basis of a heat balance conducted continuously with the aid of a process computer.Type: GrantFiled: September 12, 2008Date of Patent: August 16, 2011Assignee: BASF SEInventors: Jörg Heilek, Peter Schlemmer, Ulrich Hammon, Klaus Joachim Müller-Engel

Patent number: 7575932Abstract: The invention relates to a method for monitoring exothermic reactions in a reactor, in which one or more starting materials react exothermically to give at least one product, and at least one gas is present in the reactor during operation as intended or during a runaway, comprising the following process: A) measurement and storage of an initial temperature and an initial pressure in the reactor, B) calculation of the amount of products and starting materials present in the reactor from an energy balance, C) calculation of a maximum pressure raise that occurs on stepwise reaction of the amount of starting materials present, and D) calculation of a runaway pressure from the maximum pressure raise that occurs, calculated in step C), and the measured initial pressure stored in step A).Type: GrantFiled: June 6, 2003Date of Patent: August 18, 2009Assignee: BASF AktiengesellschaftInventors: Ulrich Nieken, Jobst Rüdiger von Watzdorf, Jochen Keβler, Christina Benthack, Hubertus Kröner, Thomas Hauff, Peter Schlemmer

Patent number: 7115775Abstract: ?,?-ethylenically unsaturated aldehydes and/or carboxylic acids are prepared by means of a two-stage catalytic gas-phase oxidation in which a gas mixture comprising at least an alkane or alkene having from three to six carbon atoms and oxygen is subjected to a catalytic oxidation reaction, in the first stage (1). oxygen is added to the gases produced in the first stage (1) and the resulting mixture is introduced into the second stage (2) in which it is subjected to a further catalytic oxidation reaction. In the process of the present invention, a signal which correlates with the oxygen content of the reaction gases before and/or after the addition of oxygen between the first and second stages (1, 2) is generated and the oxygen addition is regulated as a function of the signal.Type: GrantFiled: April 8, 2002Date of Patent: October 3, 2006Assignee: BASF AktiengesellschaftInventors: Thomas Buschulte, Volker Diehl, Bernd Hagen, Volker Huth, Wolfgang Kasten, Peter Schlemmer, Axel Schroth
