Abstract

A positioner is provided for placing plaque or wire penetrameters, as used in radiographic inspection, in close proximity with the inner wall of tubing at any desired location along the tubing. The positioner head carrying the penetrameter is inflatable whereby it is positioned in the deflated condition, inflated to place the penetrameter against a weld to be inspected in the tubing wall, and then deflated during removal. If desired, the penetrameter holder may be used to center the radiographic source on the axis of the tube.

Ultrasonic probe system for the bore-side inspection of tubes and welds therein

Patent Cook, K. Von (Clinton, TN); Koerner, Dan W. (Clinton, TN); Cunningham, Jr., Robert A. (Powell, TN); ...

A probe system is provided for the bore-side inspection of tube-to-header welds and the like for small diameter tubes. The probe head of the system includes an ultrasonic transmitter-receiver transducer, a separate ultrasonic receiver, a reflector associated with the transducer to properly orient the ultrasonic signal with respect to a tube wall, a baffle to isolate the receiver from the transducer, and means for maintaining the probe head against the tube wall under investigation. Since the probe head must rotate to inspect along a helical path, special ultrasonic signal connections are employed. Through the use of the probe, flaws atmore »« less

Lens positioner with five degrees of freedom

Patent Kobierecki, Marian W. (Livermore, CA); Rienecker, Jr., Frederick (Livermore, CA)

A device for positioning lenses precisely with five degrees of freedom (three translations and two angular rotations). The unique features of the device are its compact design, large clear aperture, and high degree of positioning accuracy combined with five degrees of freedom in axis motion. Thus, the device provides precision and flexibility in positioning of optical components. BACKGROUND OF THE INVENTION The invention described herein was made in the course of, or under, Contract No. AT(29-1)-1183, with the United States Energy Research and Development Administration.
