Patent number: 11236615Abstract: A stator assembly, at a compressor mid-plane in a gas turbine engine, to be mounted around a rotor disc, enables access to the rotor disc (e.g., for trim balancing), without requiring disassembly of the stator assembly and/or a compressor case in which the stator assembly is housed, via a removable stator vane. The stator assembly may comprise vane apertures, aligned along a radial axis, that hold the removable stator vane when inserted into the stator assembly, and provide a radial pathway to the rotor disc, when the removable stator vane is removed from the stator assembly. In addition, a case access assembly may seal the removable stator vane in place within a compressor case when engaged, and provide access to the removable stator vane and radial pathway through the compressor case when disengaged. This enables trim balancing of a mid-plane compressor rotor assembly through the stator assembly and compressor case.Type: GrantFiled: September 1, 2020Date of Patent: February 1, 2022Assignee: Solar Turbines IncorporatedInventors: David A. Burton, Kwok-Kwong Ben Tse, David Lau

Patent number: 9945386Abstract: A system and method for detecting the rotation breakaway of a spacer from a compressor rotor disk are disclosed herein. The method includes detecting a disk sensed feature and a spacer sensed feature on the compressor rotor disk and the spacer respectively. The method also includes comparing the timing between the two to a predetermined threshold to determine whether the relative position of the spacer to the compressor rotor disk exceeds a predetermined amount. The predetermined amount may be selected to determine whether an imbalance, rubbing, or binding can occur in the gas turbine engine or to determine whether anti-rotation features have been broken.Type: GrantFiled: February 11, 2016Date of Patent: April 17, 2018Assignee: Solar Turbines IncorporatedInventors: David Tai Wai Lee, Kwok-Kwong Ben Tse, Kenneth Gregory Thomas, Ching Kai Chan, Jorge Hernandez-Maldonado

Patent number: 9468368Abstract: An ophthalmic endo-illumination system includes a light source that produces a light beam, a fiber port that receives an optical fiber, a condenser that couples at least a portion of the light beam into the optical fiber received at the fiber port, and a beam splitter disposed between the fiber port and the condenser. The beam splitter is configured to receive the light beam from the condenser and split the light beam into a first beam which is coupled to the optical fiber and a second beam which is coupled to a monitoring fiber. An optical sensor is provided to detect an amount of the second beam output from the monitoring fiber. The coupling efficiency of the first beam coupled into the optical fiber may be determined based on the amount of the second beam output from the monitoring fiber.Type: GrantFiled: August 26, 2014Date of Patent: October 18, 2016Assignee: Novartis AGInventors: Ronald T. Smith, Ben Tse, Vit Ulinskas

Patent number: 8950724Abstract: A mounting system is provided to couple an engine unit including a turbine engine portion coupled to a gearbox portion about an axial axis to a support structure. An aft mounting device can couple the turbine engine portion to the support structure. A force determinator can be configured to determine a force load of the engine unit at the location of the aft mounting device. The length of the aft mounting device is adjustable between the turbine engine portion and the support structure in a radial direction to substantially align the gearbox portion and the engine portion relative to the axial axis. The aft mounting device may be sized to a desired length to correspond to a force load of the engine unit during the running condition.Type: GrantFiled: June 28, 2012Date of Patent: February 10, 2015Assignee: Solar Turbines Inc.Inventors: Kenneth Hurst, Edward Sieveking, Kwok-Kwong Ben Tse, Eric Blankenship
