| 20160376900 | STATOR DEVICE FOR A CONTINUOUS-FLOW MACHINE WITH A HOUSING APPLIANCE AND MULTIPLE GUIDE VANES - A stator device for a continuous-flow machine with a housing appliance and multiple guide vanes that are arranged in a circumferentially distributed manner at the housing appliance. The guide vanes are respectively embodied with a blade leaf and respectively at least one platform. At least in certain areas, the platforms form a surface of an annular channel through which working fluid flows during operation of the stator device, and are mounted so as to be adjustable with respect to the housing appliance. Here, a gap area is provided that at least in certain areas is formed by a radial gap—with respect to a longitudinal axis of the platform 4—between the platform and the housing appliance in the area of the surface of the annular channel. A sealing appliance is provided in the area of the gap. | 12-29-2016 |
| 20160376912 | RELATIVE POSITION MEASUREMENT - A feedback sensor system is provided. The feedback sensor system includes a first ring rotatable about an axial direction and a second ring also rotatable about the axial direction. The first ring includes one or more first ring features and the second ring includes one or more second ring features. The feedback sensor system also includes a sensor directed at the surface of the first ring for sensing a parameter influenced by the one or more first ring features and the one or more second ring features. The sensor may determine a position of the first ring relative to the second ring by sensing the parameter. | 12-29-2016 |
| 20160377087 | SEAL CARRIER, GUIDE VANE RING AND TURBOMACHINE - The segmented seal carrier of a guide vane ring of a turbomachine has a number of segments that form two half-rings of the seal carrier when assembled. They are clamped together by their opposite-lying, corresponding lateral contact regions. | 12-29-2016 |
