Patent number: 7225106Abstract: The present invention relates to a data processing system and method for seamlessly integrating laboratory information management system (LIMS) functionalities into an enterprise resource planning (ERP) system. The invention enables to keep the additional complexity that is required for the provision of LIMS functionalities at a minimum as all laboratory instrumentation setup information is centrally stored in a server computer but not in the ERP system.Type: GrantFiled: October 7, 2004Date of Patent: May 29, 2007Assignee: Bayer Business Services GmbHInventors: Matthias Dräger, Rainer Schmitz, Gerhard Maldener, Dirk Spingat

Patent number: 6654548Abstract: The invention relates to a method for control of the speed of rotation of a separately excited direct current motor for model vehicles, the speed of rotation of the motor being controlled by means of a pulse sequence, the motor being alternately supplied with a supply voltage during a switch-on period and disconnected from the supply voltage during a switch-off period, the duration of the switch-off period being dependent on the deviation of an actual value from a set value for the speed of rotation of the motor. In order to further develop the method in such a way that the separately excited motor has a low noise output and stable control is possible over a wide range of speed of rotation, it is proposed that a pulse width modulated signal is provided, the pulse width of which is dependent on the average torque loading of the motor, and that the pulse width modulated signal is combined with the pulse sequence by an AND-operation.Type: GrantFiled: September 27, 2002Date of Patent: November 25, 2003Assignee: Gebr. Maerklin & Cie. GmbHInventor: Rainer Schmitz

Patent number: 5841037Abstract: In the process for the continuous collection of pulverulent or dusty samples from a particle-laden stream, a sample stream is drawn off from a particle-laden main stream in a pneumatic conveying line 17 and passed via a collection line 9 to a particle size measurement device 10. In order to reduce spin, the main stream in the conveying line 17 is passed through a venturi-like cross-sectional constriction 3, 4, 5, the cross-sectional area of which is 10 to 60% of the free cross-sectional area of the conveying line 17. Samples are then collected downstream from the cross-sectional constriction through one or more probe tubes 7, wherein a partial stream is collected from the main stream parallel to the direction of flow thereof.Type: GrantFiled: February 27, 1997Date of Patent: November 24, 1998Assignee: Bayer AktiengesellschaftInventors: Benno Ulfik, Mathias Benz, Jorg Rainer Schmitz, Heiko Herold
