| 20080210264 | Turbine Cleaning - Depending on the actual operating situation and the composition of the fuels used for driving the internal combustion engine, contamination of the moving blades, of the guide device and of the turbine casing parts occurs sooner or later in the exhaust gas turbine. According to the invention, a small quantity of cleaning fluid is fed continuously or cyclically into the exhaust gas flow of an exhaust gas turbine and is directed onto the components to be cleaned. The small quantity of cleaning fluid can be fed in with unchanged operation of the internal combustion engine, such that the exhaust gas turbine can be cleaned or kept clean within the entire operating range of the internal combustion engine. Fluctuations in the power output of the internal combustion engine on account of requisite cleaning of the exhaust gas turbine therefore do not occur. Furthermore, the formation of thermostress cracks in the critical turbine casing parts is largely avoided. | 09-04-2008 |
| 20110162359 | DEVICE FOR SEALING A BEARING HOUSING OF AN EXHAUST-GAS TURBOCHARGER - The device serves for sealing a bearing housing of an exhaust-gas turbocharger, from which a rotor is led into a chamber of the turbocharger subjected to a mass flow. The device includes a sealing ring arranged in a groove of the rotor, a seat, arranged on the bearing housing and on which a pre-stressed sealing ring is secured by an outward-facing circumferential surface, and a radially extending separation gap, which leads annularly around the axis of rotation of the rotor and is defined by two superimposed sliding surfaces, the first of which is arranged on a first face of the sealing ring and the second of which is arranged on a first flank of the groove. In order to reduce a heat input into the sealing ring caused by lapping of the sealing ring during operation of the exhaust-gas turbocharger, a depression annularly around the axis is formed into the second flank of the groove. The depression is defined radially outwards by an annular body formed into the rotor. The annular body forms a portion of an external face of the rotor. The annular body includes a radially oriented annular edge, which adjoins the external face and which serves to reduce the size of a lapping face, which is produced as the sealing ring strikes against the second groove flank. | 07-07-2011 |

| 20100326218 | IDENTIFYING A SUBJECT WITH AN INCREASED RISK OF INVASIVE MOLD INFECTION - The present invention provides a method of identifying a subject having a haplotype in a toll-like receptor 4 gene of the subject that is associated with an increased risk of invasive mold infection in a recipient of a transplant from the subject, comprising genotyping the subject for the presence of particular single nucleotide polymorphisms or haplotypes in the toll-like receptor 4 gene of the subject, wherein the detection of said single nucleotide polymorphism(s) and/or haplotype(s) identifies the subject as having a single nucleotide polymorphism and/or haplotype associated with an increased risk of invasive mold infection in a recipient of a transplant from the subject. Also provided herein are methods of identifying an immunocompromised subject as having an increased risk of invasive mold infection and/or increased risk of mortality and/or increased risk of an impaired or altered immune response, by detecting the single nucleotide polymorphisms or haplotypes in the toll-like receptor 4 gene of this invention in the subject. | 12-30-2010 |
| 20110165124 | METHODS FOR DIAGNOSING OR PREDICTING HEPATITIS C OUTCOME IN HCV INFECTED PATIENTS - The present invention relates to in vitro methods of determining a susceptibility to non-response to a hepatitis C treatment or a susceptibility to spontaneous hepatitis C clearance in a subject infected with hepatitis C. | 07-07-2011 |

| 20080261744 | GEAR UNIT AND USE OF THE SAME - The gear unit for use with a manually adjustable electric component has a manually operable adjusting shaft and a reduction gear including a rotatable ball cage and a plurality of balls as well as a race ring element having a spring and retaining portion that encircles the race ring externally. Such a gear unit allows greatly reduced dimensions and furthermore offers a considerable dielectric strength. | 10-23-2008 |
| 20100061723 | OPTICAL SENSOR SYSTEM, OPTICAL SENSOR DEVICE AND BUS SEGMENT FOR CONNECTING THE DEVICE TO A BUS OF THE SYSTEM - An optical sensor system comprises one or more optical sensor devices, a master device and an electrical bus connecting the sensor devices to the master device. The bus comprises a signal daisy chain for the transmission of synchronization events. The sensor devices are adapted to detect a synchronization event at a signal input terminal, to time an optical activity based on this synchronization event and to provide at a signal output terminal a synchronization event delayed by an offset time with respect to the detected synchronization event. A property of the synchronization events provided by the sensor devices is indicative of an output value of the respective sensor device, corresponding to a state of an optical section to which the sensor is sensitive. Diodes are connected between the signal output terminals of the sensor devices and a signal line of the bus, which is connected to a signal input terminal of the master device, so that the latter receives the synchronization events from the sensor devices. The master device comprises means for extracting the output values of the sensor devices from these synchronization events. A sensor device for such a system comprises an enclosure of cuboid outer shape adapted to be mounted to a mounting rail so that the longitudinal direction of the rail is perpendicular to lateral sides of the enclosure. An electrical connector with the signal input and output terminals and with power supply terminals is arranged at a side connecting the lateral sides of the enclosure. Bus segments are provided for connecting the sensor devices to the system bus. | 03-11-2010 |
