Marker For Pipeline Apparatus And Method
US Patent:
8358134, Jan 22, 2013
Filed:
Aug 13, 2009
Appl. No.:
12/541076
Inventors:
Philip M. Hoyt - Murray UT, US
Assignee:
Pure Technologies Ltd. - Calgary
International Classification:
G01V 3/08
US Classification:
324326, 324332
Abstract:
Defects in a pipeline may be detected by an in-line inspection tool passing therethrough. However, as the tool travels through the pipeline, errors associated with certain onboard components may accumulate. These errors may reduce the accuracy with which the locations of detected defects can be determined. Accordingly, markers may be positioned at various locations along the pipeline. Each marker may include a radio receiver to receive signal transmitted by an in-line tool passing thereby and one or more magnetic flux detection systems that may detect a magnetic field emanating from the in-line tool. The radio receiver may include an antenna comprising two or more coils connected in series and positioned side-by-side. The flux detection system may include one or more flux concentrators to amplify the strength of the magnetic field. Signals received through the antenna or flux detection system may be used to correct any errors associated with the onboard components charting the progression of the in-line tool through the pipeline.
Pseudorandom Binary Sequence Apparatus And Method For In-Line Inspection Tool
US Patent:
8322219, Dec 4, 2012
Filed:
Aug 7, 2009
Appl. No.:
12/538104
Inventors:
Philip M. Hoyt - Murray UT, US
Assignee:
Pure Technologies Ltd. - Calgary
International Classification:
G01N 29/00, G01N 27/82
US Classification:
73602, 73643, 324240
Abstract:
An in-line inspection tool is disclosed for inspecting the wall of a pipeline while traveling therethrough. The in-line inspection tool may include a transmitter, a signal generator, one or more receivers, and a decoder. The signal generator may generate a pseudorandom signal, generate an inspection signal, and drive the transmitter with a convolution of the pseudorandom signal and the inspection signal. The transmitter may transmit the convoluted signal to the wall of the pipeline. One or more receivers may receive from the wall of the pipeline a received signal comprising at least one of the convoluted signal and a reflection of the convoluted signal. The decoder may identify the inspection signal within the received signal by cross correlating the received signal and the pseudorandom signal.

Linkage Assembly For In-Line Inspection Tool
US Patent:
7798023, Sep 21, 2010
Filed:
Jun 4, 2009
Appl. No.:
12/478137
Inventors:
Philip M. Hoyt - Murray UT, US
Arthur K. Fox - Murray UT, US
Arthur K. Fox - Murray UT, US
Assignee:
Electromechanical Technologies, Inc. - Murray UT
International Classification:
G01M 19/00
US Classification:
738658
Abstract:
An in-line inspection tool comprising sensors mounted on inspection assemblies is disclosed. Each inspection assembly may be connected to the rest of the in-line inspection tool by two linkages. A first linkage may pivotally connect at one end thereof to a first end of an inspection assembly and pivotally connect at the other end thereof to the rest of the in-line inspection assembly. A second linkage may pivotally connect at one end thereof to a second end of the inspection assembly and pivotally connect at the other end thereof to the rest of the in-line inspection tool. The second linkage may comprise a first section and a second section pivotally connected to one another. Accordingly, the first and second linkages may support, exclusively through pivoting, both translational and rotational movement of the inspection assembly within a radial plane containing the central axis of the in-line inspection tool.
Spiral Magnetic Field Apparatus And Method For Pipeline Inspection
US Patent:
8089273, Jan 3, 2012
Filed:
Apr 8, 2011
Appl. No.:
13/083422
Inventors:
Philip M. Hoyt - Murray UT, US
International Classification:
G01R 33/12, G01N 27/72
US Classification:
324220
Abstract:
A system and method are disclosed for inspecting the wall of a pipeline while traveling therethrough. The system may comprise a portion of pipe comprising a pipe wall forming a cylindrical tube defining a circumferential direction and an axial direction. The system may further include an in-line inspection tool positioned within the portion of pipe. The in-line inspection tool may include a frame extending in the axial direction and at least one magnet connected to the frame and positioned to generate a magnetic field. The magnetic field may be orientated obliquely with respect to the circumferential and axial directions of the pipeline. The inspection tool may include a transmitter connected to the frame to generate an inspection signal within the magnetic field.
Debris Resistant Bearing System And Method
US Patent:
8215844, Jul 10, 2012
Filed:
May 17, 2010
Appl. No.:
12/781655
Inventors:
Philip M. Hoyt - Murray UT, US
Assignee:
Pure Technologies (U.S.) Inc.
International Classification:
F16C 19/00, G01M 3/08
US Classification:
384473, 73 491
Abstract:
A system and method are disclosed for protecting bearings operating in dirty environments. The system may include a reservoir of lubricant, a bearing, and a regulator. The bearing may border on both the dirty environment and the reservoir. Accordingly, the bearing may be exposed to the solid particles carried by the fluid within the environment, as well as the lubricant of the reservoir. The regulator may ensure that the pressure within the reservoir is greater than the pressure of the dirty environment. Due to the higher pressure within the reservoir, the bearing may be preferentially filled with lubricant rather than dirty fluid from the environment.

Arthur K. Fox - Murray UT, US
International Classification:
G01M 19/00
US Classification:
738658
Abstract:
An in-line inspection tool comprising a sensor suite, a processor processing the signal generated by at least one sensor of the sensor suite, and a canister housing the processor is disclosed. The canister may comprise a canister body formed as a hollow cylinder extending along a central axis from a first end to a second end. The canister may further comprise a canister lid inserted within the first end of the canister body. An alignment mechanism may prevent rotation of the canister lid with respect to the canister body about the central axis. A retaining ring may threadedly engage the first end of the canister body to maintain the canister lid within the first end of the canister body.
Defect Discriminator For In-Line Inspection Tool
US Patent:
7859256, Dec 28, 2010

Inventors:

Arthur K. Fox - Murray UT, US
Assignee:
Electromechanical Technologies, Inc. - Murray UT
International Classification:
G01R 33/12
US Classification:
324220
Abstract:
An in-line inspection tool comprising primary and secondary sensor suites is disclosed. The primary sensor suite may detect both interior and exterior defects. The secondary sensor suite may comprise a plurality of housings distributed in the circumferential direction around the body of the tool. Each housing may contain at least one flux sensor and at least one flux concentrator. The flux concentrator may increase the flux delivered to the flux sensor, thereby increasing the sensitivity of the secondary sensor suite while reducing the number of flux sensors required. The secondary sensor suite may detect substantially exclusively interior defects. By comparing the outputs of the primary and secondary sensor suites, a user may determine whether a defect is located on the interior or exterior of a pipeline being inspected.
