Publication number: 20070245911Abstract: A drive for a rotary printing press has a clutch with improved reliability in the main drive gear train. The drive has a gearwheel mechanism for transmitting a rotational movement of transfer drums during delivery of a printing material. The gearwheel mechanism includes a gearwheel pair with a driving gearwheel and a driven gearwheel and the driven gearwheel, which is arranged coaxially with respect to the driving gearwheel, is coupled during delivery to a shaft journal of a transfer drum. A clutch is provided for selectively producing and interrupting the transmission of torque between the driving gearwheel and the driven gearwheel. At least one motor is provided for feeding a torque into the gearwheel mechanism. A stepup gear mechanism is arranged in the torque flow between a clutch half of the clutch and a gearwheel.Type: ApplicationFiled: April 25, 2007Publication date: October 25, 2007Inventors: Roland Angert, Jens Friedrichs, Christian Gorbing, Gerald Hauptmann, Michael Kruger, Olaf Lorenz, Markus Mohringer, Frank Schaum, Thomas Schmidt, Martin Seipel, Volker Weindel

Publication number: 20070234913Abstract: A drive for a rotary printing press makes a reliable transmission of high torques possible and, with low structural expenditure, setting of the phase in the main drive gear train. In the drive for a rotary printing press, two adjacent transfer drums are mounted with shaft journals in side walls, a gearwheel of the gearwheel mechanism is disposed fixedly in terms of rotation on the shaft journals and the gearwheels are not in direct engagement with one another. The gearwheels of the adjacent transfer drums are permanently in engagement in each case with one intermediate gear. The gearwheels of the adjacent transfer drums and the intermediate gears are kept at a spacing from one another in each case with one lever. The intermediate gears are kept at a spacing in each case from one another with a coupler. The coupler can be disconnected and the engagement of the teeth of the intermediate gears can be canceled.Type: ApplicationFiled: April 10, 2007Publication date: October 11, 2007Inventors: Roland Angert, Jens Friedrichs, Christian Gorbing, Gerald Erik Hauptmann, Michael Kruger, Olaf Lorenz, Markus Mohringer, Frank Schaum, Thomas Schmidt, Martin Seipel, Volker Weindel

Patent number: 6987390Abstract: Testing a transformer by applying to the transformer a test signal, the frequency of which may be lower than the nominal frequency of the transformer. The voltage of the test signal may also be lower than the nominal voltage of the transformer. A number of frequency-dependent parameters are measured, particularly the eddy current resistance and the hysteresis curve of the transformer, in order to derive a simulation model which simulates the behavior of the transformer at different frequencies. Using this simulation model, it is possible to predict operating parameters of the transformer, such as the terminal voltage on the secondary and the terminal current in the secondary, during operation with a frequency deviating from the frequency of the test signal, particularly during operation with the nominal frequency of the transformer.Type: GrantFiled: September 11, 2003Date of Patent: January 17, 2006Assignee: Omicron Electronics GmbHInventors: Franz Süss, Michael Krüger, Friedrich Kaufmann

Publication number: 20050187972Abstract: A computer system and method is disclosed that analyzes and corrects retail data. The system and method includes several client workstations and one or more servers coupled together over a network. A database stores various data used by the system. A business logic server uses competitive and complementary fusion to analyze and correct some of the data sources stored in database server. The data fusion process itself is an iterative one—utilizing both competitive and complementary fusion methods. In competitive fusion, two or more data sources that provide overlapping attributes are compared against each other. More accurate/reliable sources are used to correct less accurate/reliable sources. In complementary fusion, relationships modeled where data sources overlap are projected to areas of the data framework in which fewer sources exist—enhancing the accuracy/reliability of those fewer sources even in the absence of the other sources upon which the models were based.Type: ApplicationFiled: February 20, 2004Publication date: August 25, 2005Inventors: Michael Kruger, Cheryl Bergeon, Arvid Johnson

Patent number: 6877430Abstract: A gripper device in a sheet-processing machine includes a gripper, a gripper pad associated with the gripper and a first drive for moving the gripper out of an opened position thereof into a closed position thereof. The gripper is cooperatively engageable with the gripper pad for producing a clamping force for holding sheets being processed.
