US Patent:

20120314223, Dec 13, 2012

Filed:

Jun 11, 2012

Appl. No.:

13/493806

Inventors:

Phillip Dewayne Bondurant - Covington WA, US
David William Rook - Kent WA, US
David H. Bothell - Lake Tapps WA, US
Christian Robert Lentz - Benton City WA, US
David Jack Savage - Renton WA, US

Assignee:

Quest Metrology, LLC - Kent WA

International Classification:

G01B 11/24

US Classification:

356601

Abstract:

An apparatus configured to measure at least one physical characteristic of an threaded surface (e.g., an internally threaded surface) of an object is provided. The apparatus uses optical triangulation to perform non-contact characterization of the threaded surface. The apparatus can be used to characterize various aspects of the threaded surface, including generating the measurements required to produce a longitudinal cross-sectional profile of the threaded surface.

Appl. No.:

8/063596

International Classification:

G21C 1900
B08B 300

US Classification:

376316

Abstract:

An apparatus for cleaning inlet mixers while they remain in their operating position within a nuclear reactor. A cleaning tool is inserted by remote control into the inlet mixer via a secondary inlet opening. Following insertion of the cleaning tool, the internal surfaces of the inlet mixer are cleaned with a waterjet created from an ultra-high-pressure source and directed by controlled positioning of a cleaning head having a nozzle which scans the cleaning waterjet across the surface to be cleaned. The cleaning system includes a nozzle cleaning tool, a throat/barrel/flare cleaning tool, pumping systems for supplying ultra-high-pressure equal to at least 20,000 psi and low-pressure water to an installed cleaning tool, a launching system located at the top of the opened reactor vessel for feeding the water conduits (power), control cables, monitoring cables (instrument) and cleaning tool into and out of the inlet mixer, and a computerized process monitoring and control system.

US Classification:

Abstract:

A method for cleaning inlet mixers while they remain in their operating position within a nuclear reactor. A water-powered cleaning tool is inserted by remote control into the inlet mixer via a secondary inlet opening. Following insertion of the cleaning tool, the internal surfaces of the inlet mixer are cleaned with a waterjet created from an ultra-high-pressure source and directed by controlled positioning of a cleaning head having an nozzle which scans the cleaning waterjet across the surface to be cleaned. The cleaning system for carrying out the method includes a nozzle cleaning tool, a throat/barrel/flare cleaning tool, pumping systems for supplying ultra-high-pressure equal to at least 20,000 psi and low-pressure water to an installed cleaning tool, a launching system located at the top of the opened reactor vessel for feeding the water conduits (power), control cables, monitoring cables (instrument) and cleaning tool into and out of the inlet mixer, and a computerized process monitoring and control system.

G01N 17/04

US Classification:

324700, 439577, 738658

Abstract:

The systems, apparatus, and methods disclosed herein provide access to systems located within a closed structure, such that the systems are traditionally difficult for humans to access. Exemplary structures include an engine compartment, airplane wing, or fuselage. This access allows a system located within the structure to be electrically coupled with an electrical I/O device located outside the structure. Access to a system located within the closed structure is provided by way of a hole.
