  • Audible techniques for the perception of nondestructive evaluation information
    Patent number: 5285521
    Abstract: A method and apparatus for utilizing the sound and pattern recognition capabilities of the human auditory system, which takes information contained in typical instrumentation signals in the form of amplitude, frequency, and time characteristics, and converts this information into sound qualities and characteristics which are recognizable by the human listener. The method and apparatus digitizes the analog amplitude, frequency, and time information, and selects appropriate sound characteristics into which it may encode this information in standardized form that is recognizable to the human listener. The method allows for the testing or inspection of materials using nondestructive evaluation techniques in a manner that allows the tester to interpret the information provided by the testing system, either exclusively through his auditory senses, or through his auditory senses in conjunction with visual indicators.

  • Electromagnetic flux leakage inspection system for ferromagnetic tubes
    Patent number: 4649343
    Abstract: An electromagnetic inspection system for detecting, in-situ, the location and character of flaws in a relatively long, thick-walled small bore tube of a heat exchanger wherein a resultant magnetic field is induced in the wall of the tube of selected direction and magnitude by the vector addition of the magnetic fields produced by two magnetic field generators, at least one of which is carried by a scanner for traversing the tube and having an array of sensors mounted in close proximity to the wall of the tube generating a unique signal as the scanner passes a flaw in the tube.
    Type: Grant
    Filed: December 27, 1983
    Date of Patent: March 10, 1987
    Assignee: The Babcock & Wilcox Company
    Inventors: Robert J. Birchak, Flora J. Harris, Amos E. Holt
  • Method for generating the eddy current signature of a flaw in a tube proximate a contiguous member which obscures the flaw signal
    Patent number: 4194149
    Abstract: A method for deriving the eddy current signature of a flaw in a tube proximate a contiguous member which is obscured in the composite signature of the flaw and contiguous member by subtracting from the composite signature a reference eddy current signature generated by a facsimile of the tube and contiguous member.
    Type: Grant
    Filed: December 15, 1977
    Date of Patent: March 18, 1980
    Assignee: The Babcock & Wilcox Company
    Inventors: Amos E. Holt, Allen E. Wehrmeister, Hubert L. Whaley
  • Fluid coupled test probe
    Patent number: 4033178
    Abstract: A mobile fluid coupled test probe wherein communication between a transducer and an object under inspection is maintained through a fluid couplant which also serves to maintain engagement of the probe with the object.
