Patent number: 10041371Abstract: A robotically articulated inspection scope (56, 69) inserted into a pilot fuel nozzle port (58) of a turbine engine (20) for in-situ measurement of gaps (59) between tips of turbine blades (40A) and the surrounding shroud (44). A non-contact gap measuring device (52) on a distal end (79) of the scope may be navigated through a combustor (28) and transition duct (34) into a position proximate a blade tip gap. The scope may be controlled via computer (68) via a robotic drive (66) affixed to the pilot fuel nozzle port. Multiple scopes may be used to measure gaps (59A-D) at multiple azimuths of the turbine simultaneously. The turbine disk (37) may be rotated on its operating turning gear to sequentially measure each blade at each azimuth. The computer may memorize an interactively navigated path for subsequent automated positioning.Type: GrantFiled: February 6, 2015Date of Patent: August 7, 2018Assignee: SIEMENS ENERGY, INC.Inventors: Joshua DeAscanis, David Letter, Alejandro Bancalari, Clifford Hatcher, Jr.

Patent number: 9140817Abstract: A steerable or non-steerable, magnetic dipole antenna for Measurement-While-Drilling (MWD) or Logging-While-Drilling (LWD) applications. The antenna elements use a hole arrangement in addition to grooves in a steel tool body, which is typically a drill collar. This antenna embodiment is extremely robust, meaning that does not significantly reduce the structural integrity of the tool body in which it is disposed. The antenna embodiment is also relatively wear resistant. The resultant magnetic dipole generated by this antenna is also electrically steerable in inclination angle from a common origin. A variable dipole moment inclination angle combined with independently measured tool rotation orientation during normal drilling allows the antenna to generate a magnetic dipole moment that may be directed at any three dimensional angle and from a common origin point at the centroid of the antenna. The antenna can also be embodied to be more sensitive to resistivity in a particular azimuthal direction.Type: GrantFiled: September 1, 2010Date of Patent: September 22, 2015Assignee: PRECISION ENERGY SERVICES, INC.Inventors: Macmillan M. Wisler, Larry W. Thompson, Jian-Qun Wu, Lance Pate

Patent number: 8512261Abstract: A Perineal elasticity meter having a circular central stem marked with millimeter markings and a sleeve portion surrounding the circular stem. Hinges connect the sleeve to expanders that extend from the circular stem. The perineal elasticity meter is configured to be inserted into the vagina of a patient in order to measure the elasticity of the perineal area. The sleeve includes an opening that shows a circumferential measurement achieved by the expansion of the expanders, as the sleeve moves along the central stem. Another perineal elasticity meter includes two stems connected via a hinge at a proximal portion of the stems. The proximal portions of the stems are configured to be inserted into the vagina of a patient and a measurement is taken of a distance between the expanded distal portion of the stems, thereby measuring the elasticity of the perineal area.Type: GrantFiled: June 25, 2008Date of Patent: August 20, 2013Inventors: Miriam R. Diniz Zanetti, Mary Nakamura

Patent number: 6647637Abstract: A downhole caliper instrument utilizing a linear or arcuate magneto resistive sensor to determine the position of one or more caliper arms which extend from a carrier tool to touch the surface of a borehole wall. A processor and firmware are included to calculate and plot the borehole radius. A plurality of magneto resistive sensors are provided to calculate the sine, cosine and tangent for accurate motion of each independent arm. The magneto resistive sensors sense the position a precise magnetic ruler linked to the caliper arm. The position of the caliper arm determines the radius of the borehole. Calculation of Radius/Diameter is preferably performed in the computer on surface. The downhole controller's firmware controls the multiplexer switching, A/D conversion and other functions.Type: GrantFiled: October 29, 2001Date of Patent: November 18, 2003Assignee: Baker Hughes IncorporatedInventor: Helmut Lechen

Patent number: 6192593Abstract: There is disclosed an internal sizing apparatus comprising a pneumatically activated probe that moves axially within a shoe and non-destructively measures the interior dimensions of the shoe. A linear pneumatic actuator is mounted between a heel piece and a probe. A linear potentiometer is mounted above the actuator and also connects to the probe. The apparatus is inserted into a shoe with the heel piece seated against the interior heel portion of the shoe. A computer system controlling the actuator extends the probe linearly into the shoe until the probe contacts the toe portion of the shoe. The potentiometer then measures the linear distance traveled by the probe and thus determines the internal linear dimension of the shoe. Depending on the type of probe, three-dimensional internal measurements of the shoe can also be quantified.Type: GrantFiled: September 2, 1998Date of Patent: February 27, 2001Assignee: Nike International Ltd.Inventors: Bob Borchers, Chris Edington, Michael Hailey, Bruce Kilgore, Lynn O'Mohundo
