Patent number: 7269953Abstract: A method of controlling a gas turbine system (10) may include controlling an inlet guide vane position (98) to maintain a turbine (24) exhaust temperature at a corrected value that is a function of a compressor (12) inlet temperature and a turbine (24) normalized load. The method may include selecting the minimum value (138) of a part load tunable value, a part load maximum value and a fixed maximum value of a turbine (24) exhaust temperature for the corrected value. A corrected value setpoint may be determined (94) for the gas turbine system (10) operating at a part load condition where at least one of a fuel flow rate and the inlet guide vane position is controlled (98) so the corrected value does not exceed the corrected value setpoint. The corrected value may prevent a turbine (24) engine from exceeding its firing temperature during operation and ensure the engine operates within combustor dynamics and emissions limits.Type: GrantFiled: August 27, 2004Date of Patent: September 18, 2007Assignee: Siemens Power Generation, Inc.Inventors: Satish Gadde, Christopher Humphrey, Stefan Schneider, Fadi Tadros, Jatinder Singh

Patent number: 7264767Abstract: A process and a device serve for decreasing the oxygen content of a copper melt. One or more flushing plugs, from which a scavenging gas emerges, are arranged in the perpendicular direction in the lower region of the copper melt. The scavenging gas ascends into the copper melt, and the copper melt itself is electrically stirred. The copper is initially melted in a shaft furnace, and then it is led to a treatment furnace via a transportation channel. As a result of flowing out of the flushing plugs, the scavenging gas ascends into the copper melt both in the region of the transportation channel and also in the region of the treatment furnace. The scavenging gas flows out of at least one of the flushing plugs with a composition corresponding to 30% to 70% reducing gas and 70% to 30% inert gas.Type: GrantFiled: June 21, 2001Date of Patent: September 4, 2007Assignee: Norddeutsche Affinerie AktiengesellschaftInventors: Heinrich Schliefer, Alexander Khoury, Stefan Schneider

Patent number: 7223056Abstract: A blind rivet nut has a head configured as an annular flange and a shank comprising a head end, a foot end and a cylindrical bore closed at the foot end of the shank and extending from the head end to the foot end in lengthwise direction, and a second bore segment near the head end whose diameter is greater than the diameter of the first bore segment. The wall surrounding the second bore segment forms a plastically deformable region of the shank, and has an outer surface with the shape of a regular polygonal, in particular hexagonal, prism. To achieve a uniform and tightly sealing contact of the flange with the part accommodating the blind rivet nut, the wall thickness of the deformable region in the thinnest places is 4% to 6% of the least outside diameter of the deformable region.Type: GrantFiled: January 18, 2005Date of Patent: May 29, 2007Assignee: Newfrey LLCInventor: Stefan Schneider

Patent number: 7058547Abstract: A data acquisition system which includes data generating and processing units (1a, 1b, 1c), each of which includes a respective data source (3a1, 3a2, 3b1, 3c1) which serves to generate data. The data each time generated is processed by means of associated data processing means (2a, 2b, 2c 11a1, 11a2, 12a1, 12a2, 13a1, 13a2) in such a manner that each time a digital data word which comprises at least two bits is presented for output. The output of the digital data words takes place in synchronous-parallel fashion in dependence on first control signals (4, 5). Shift registers (6a, 6b, 6c) which are coupled to one another so as to form a chain propagate the digital data words in synchronous-parallel fashion in dependence on second control signals (7, 8) and are coupled to a respective associated data generating and processing unit (1a, 1b, 1c).Type: GrantFiled: May 19, 2003Date of Patent: June 6, 2006Assignee: Koninklijke Philips Electronics N.V.Inventors: Olaf Such, Francisco Morales Serrano, Stefan Schneider, Gereon Vogtmeier

Patent number: 7032716Abstract: The invention relates to a method for controlling an elevator installation with at least one shaft and a number of cars, it being possible to make at least two cars travel separately up and down along a common traveling path and a passenger being able to enter a destination call by means of an input unit disposed outside the shaft and the destination call being allocated to a car in dependence on an allocation assessment. To develop the method in such a way that the transporting capacity can be increased, with the cars which can be made to travel along a common traveling path hindering one another as little as possible, it is proposed according to the invention that, in the case of allocation of the destination call to one of the cars which can be made to travel along the common traveling path, the portion of the traveling path required for serving the destination call is assigned to this car and blocked for the time of the assignment for the other cars.Type: GrantFiled: April 28, 2005Date of Patent: April 25, 2006Assignee: ThyssenKrupp Elevator AGInventors: Peter Meyle, Stefan Schneider, Gerhard Thumm

Patent number: 7031410Abstract: The invention relates to a method of canceling noise in a signal generated by discrete multi-tone modulation. The noise is caused primarily by the transient of a transmission channel via which the signal is transmitted. The signal comprises a plurality of symbols each of which is preceded by a cyclic prefix. According to the invention, a plurality of parameters is calculated from the digitized sample values of the signal and the approximate transient of the transmission channel is calculated from said plurality of parameters. To cancel the noise the approximately calculated transient is subtracted from the digitized sample values.Type: GrantFiled: March 1, 2000Date of Patent: April 18, 2006Assignee: Infineon Technologies AGInventors: Heinrich Schenk, Stefan Schneider, Dietmar Straeussnigg
