Patents by Inventor Alexander J. Zinkosky

Alexander J. Zinkosky has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5240329
    Abstract: A method for detecting defects (10) in a workpiece (12) non-destructively, comprising subjecting the workpiece (12) to a temperature difference in relation to ambient temperature. The method provides an infrared radiometric scanner (14) having a field of view (16) which includes the workpiece (12) being tested, the radiometric scanner (14) sensing an emitted temperature pattern representative of the internal structure (10) of the workpiece (12). The method for detecting defects (10) also communicates a controller (18) with the radiometric scanner (14), the controller (18) receiving an output signal (22) from the radiometric scanner (14) indicative of the emitted temperature pattern before the workpiece (12) is allowed to achieve thermal equilibrium with the ambient environment.

  • Patent number: 4854162
    Abstract: A method of determining the location and type of dimensional defects, particularly friction generating defects, which comprises: (a) initiating simulated operation at ambient conditions of an assembly having certain sliding or rolling contact surfaces; (b) sensing any change in the temperature of such assembly surrounding each certain sliding or rolling contact surfaces (i) with a resolution of 0.02-1.0 C.degree. (preferably 0.1-0.7 C.degree.) and (ii) during a time span of 2-10 seconds measured from such initiation to provide separated voltage signals for each location; (c) converting the signals to a digitized thermal map; and (d) comparing the sensed digitized thermal map with a reference digitized thermal map for such an assembly without defects operated during the same time span and adjusted to compensate for any differing thermal conditions. Any deviations detected by such comparison representing defects.
