US Patent:

45203075, May 28, 1985

Filed:

Mar 8, 1984

Appl. No.:

6/587670

Inventors:

Arnold A. Weiss - Minneapolis MN
Dale A. Gustafson - Minneapolis MN

International Classification:

G01R 3112

US Classification:

324 54

Abstract:

A high-voltage, non-destructive inspection system for detecting nails, and/or cuts and holes in vehicle tires. The system employs a high-voltage head mounted within the tire and a reference head outside the tire opposite to the high-voltage head. The high-voltage head and reference head span the tire tread axially. The inspection is performed in one revolution of the tire. High-voltage pulses are impressed upon the high-voltage head, and the amplitude and pulse widths are variably selected, commensurate with the type of tire being tested. When a cut, hole or a nail in the tire passes between the high-voltage head and the reference head, an electric arc forms and current passes through the tire. This arc can be visually observed and also electronically detected. Upon detection, via an electronic detection circuit, a lamp lights and the tire rotation is stopped, thus facilitating location of the flaw, via a manual mode.

International Classification:

G01M 17/02

Abstract:

A system and methods for testing the integrity of a tire are disclosed. The tire is tested by powering a charging/timing circuit with a single-ended voltage supply. The single-ended voltage supply, via the charging/timing circuit, provides power to at least two test heads. The timing circuit can include various components that adjust the timing of the charge supplied.
