Abstract: A manually operable scanner includes a rectangular frame having suction cups or other mounting devices connectable to a casting or other body to be scanned with a carriage being mounted on the frame for reciprocation in a first direction. A scanner such as an ultrasonic transducer is mounted on the carriage for reciprocation in a direction perpendicular to the direction of movement of the carriage with movement of the carriage and the scanner being sensed by first and second rotary encoders each of which provides an output signal to a display indicative of the position of the transducer with respect to the rectangular frame so that upon a detection of a fault in the body being scanned, the coordinates of location of the fault are immediately available from a visual readout of the coordinates from the display means.

Abstract: A pipe cutting or end prepping device capable of use in severely restricted spaces to cut through or shape for welding a hollow cylindrical pipe wall, which includes a rotatable tool bit support or carriage assembly adapted for insertion through an end of the pipe to be cut and located within the hollow bore of the pipe having one or more tool bits to cut into the pipe wall at the cutting site. A rotatable drive coupler is provided for releasably coupling a drive motor to the tool bit support or carriage for rotating the latter, and an anchor forming assembly in the form of a radially expandable and contractable annular collet forms a cylindrical pipe gripping surface to provide a stationary anchor station along the pipe adjacent the cutting site.
