Patent number: 5313837Abstract: The invention is a compact ultrasonic tester involving rotating sensors. The processor rotates with the sensors so that the output signal of the processor goes through the slip rings, rather than the output signal of the sensors. A spraying system is incorporated in conjunction with rollers. The rollers take the applied spray on the pipe surface and paint a film on the outer pipe surface to allow a good contact for meaningful results. A floating shoe is provided for holding each sensor against the pipe wall. The sensors are biased into contact with the pipe surface and the machine can handle different diameters of pipe. By controlling the pipe speed of advance and the rotational speed of the sensors, 100 percent coverage of the pipe wall is assured. The machine is compact and can be installed behind existing electromagnetic/gamma testers without major modifications to pipe-testing facilities.Type: GrantFiled: September 26, 1991Date of Patent: May 24, 1994Assignee: ICO, Inc.Inventor: John Haynes

Patent number: 4905760Abstract: A standard size, steel oil well sucker rod coupling is machined to decrease its external diameter, producing a constant diameter along its length. Then, the coupling is machined to produce chamfers or bevels around the circumference on the ends, such that the diameter at the radial faces is less than at the body of the coupling. Next, abrasive blast-cleaning of the coupling produces a uniform, angular, anchor profile along the machined areas on the exterior of the coupling. Finally, a specially selected, fusion bonded, resinous coating is applied to the exposed surface. The radial faces may or may not be coated. The unique protective coatings impart abrasion resistance in a pumping oil well and serve as an electrical barrier to preclude electrochemical, corrosive, attack of the mild steel coupling core. Extended service life of the coupling is achieved.Type: GrantFiled: January 12, 1989Date of Patent: March 6, 1990Assignee: ICO, Inc.Inventor: Kenneth W. Gray
