Non-Invasive, High Resolution Detection Of Electrical Currents And Electrochemical Impedances At Spaced Localities Along A Pipeline
Non-Invasive, High Resolution Detection Of Electrical Currents And Electrochemical Impedances At Spaced Localities Along A Pipeline
US Patent:
5126654, Jun 30, 1992
Filed:
Apr 2, 1990

International Classification:
G01N 2726
US Classification:
324 712
Abstract:
Electrical current distribution in the soil surrounding a buried pipeline is detected by applying an AC electrical potential between the pipe and a buried electrode spaced from the pipe. The magnetic field at spaced localities along the pipe arising from currents transverse to the pipe is detected. Additionally, a potential containing a plurality of alternating frequencies is similarly applied to the pipe and the magnetic field induced by the resulting electrical current both along the pipe and transversely of the pipe is detected. The magnetic field is detected by correlation discrimination at spaced locations along the pipe and across the spectrum of the impressed frequencies. The detected data is used to determine the capacitance and resistance of the soil/pipe interface at localities along the pipe and to generate impedance plots which indicate characteristics of that interface.

International Classification:
G01N 2100, G01N 2500
US Classification:
374 45
Abstract:
The present invention provides a thermal imaging method to evaluate the surface and subsurface properties of a material and is based on techniques of optical beam deflection thermal imaging. The invention uses a localized excitation source, such as an optical beam, to provide localized heating of the sample surface. A surface thermal gradient is induced on the sample surface as heat flows, in three dimensions, from the area of localized excitation into the test material. The surface temperature gradient causes a thermal refractive lens to be generated in the fluid (gas or liquid) adjacent to the sample surface. An optical probe beam is directed through the thermal lens and is deflected by changes in a refractive index of the thermal lens. Changes in the refractive index are induced by variations of the surface temperature. In this manner, a detailed surface temperature profile can be generated which reveals surface and subsurface properties of the material tested.

US Patent:
4172382, Oct 30, 1979
Filed:
Oct 3, 1978
Appl. No.:
5/948292
Inventors:
John C. Murphy - Columbia MD
Raymond C. Cole - Baltimore MD
Raymond C. Cole - Baltimore MD
Assignee:
The Johns Hopkins University Applied Physics Laboratory - Laurel MD
International Classification:
G01M 304
US Classification:
73 405A
Abstract:
The present invention relates generally to the utilization of laser interferometry for performing detection of buried structures such as underground natural gas pipeline. More specifically, the invention relates to the use of a laser interferometer system for detecting leaks and similar defects, such as corrosion, in buried pipelines, pressurized containers or other metallic structures, based upon the sensing of subnanometer earth surface displacements produced by elastic waves which are emanated from the leak or defect and propagate in the surrounding earth medium.
