A sensor system configured to perform a method as above is also provided. | 2021-02-25 |
20210054739 | LOW POWER WATER CUT SENSING - A system for determining a water cut of a water/oil emulsion includes a water cut sensor with a magnetoelastic ribbon, an inductive coil arranged proximate to the magnetoelastic ribbon so that an electromagnetic field produced by the inductive coil electromagnetically excites the magnetoelastic ribbon, and an alternating current source. A processor is configured to determine the water cut of the water/oil emulsion based on a resonant frequency of the magnetoelastic ribbon while the magnetoelastic ribbon is excited by the inductive coil. A feed line is coupled to the water cut sensor. The feed line includes an electrical coupling between the alternating current source and the inductive coil of the water cut sensor. The feedline includes an electrical coupling between the processor and the inductive coil of the water cut sensor or the processor is coupled to an acoustic sensor. | 2021-02-25 |
20210054740 | TOOL HOLDER INSTALLATION DEVICE AND SYSTEM - A tool holder insertion device includes a frame extending from a proximal end to a distal end, the frame including first and second longitudinal arms extending between the distal end and the proximal end. The frame also includes a distal transverse arm connected to respective distal ends of the first and second longitudinal arms, a proximal transverse arm opposite the distal transverse arm, and an internal space extending from the distal transverse arm, the internal space forming an insertion opening. The tool holder insertion device also includes a drive assembly fixed to the frame, the drive assembly including a pushing surface that is movable within the internal space toward the distal end of the frame. | 2021-02-25 |
20210054741 | TURBINE DIAGNOSTICS - A turbine speed probe diagnostic system is provided. The turbine includes a speed probe and a speed reading circuit. A speed lead connects the speed probe and speed reading circuit together to transmit speed signals from the speed probe to the speed reading circuit. A speed probe diagnostic circuit is also provided for connection to the speed lead. An isolation switch is provided to isolate the speed probe diagnostic circuit during normal operation when the speed reading circuit is receiving speed signals from the speed probe. When no speed signals are being received, the isolation switch closes and the speed probe diagnostic circuit performs a test on the speed probe or speed lead. | 2021-02-25 |
20210054742 | VANE AND COMPRESSOR AND GAS TURBINE HAVING THE SAME - A compressor vane is provided. The compressor vane may include a first surface directed toward air introduced into a compressor, a second surface directed in a direction opposite to the first surface, and two tangent lines in which the first and second surfaces meet, wherein a rate of change, with respect to a height of the compressor vane, of a maximum separation distance, between the first surface and the second surface, divided by a distance from one to the other of the two tangent lines in a cross-section at one position of the height of the compressor vane in a direction starting from a portion of the compressor vane closest to a center tie rod and toward a compressor housing varies with the height of the compressor vane away from the portion of the compressor vane closest to the center tie rod. | 2021-02-25 |
