    摘要: Apparatus as provided for plugging a tube end in such a manner that the plug can be later removed. The apparatus includes a hollow plug (10) closed at the end (12) inserted into the tube (20) and open at its other end. The plug has a band (18) of ductile metal (gold, silver, or pure iron) on its outer surface which is extruded into any crevices caused by irregularities in the inner wall surface of the tube when the plug is mechanically expanded into the tube. The plug has a portion near its outer end of slightly enlarged diameter (14) to provide a light interference fit with the tube to hold the plug in place prior to and during the expanding step.

    摘要: A method and apparatus for dynamically testing a rotational torque producing device (22) during calibration under conditions simulating actual operating conditions. The torque produced by the torque producing device under controlled (28) load conditions similar to actual operating conditions is converted by a transducer (12) to an electrical signal and monitored (26) to assure that the stall torque of torque producing device (22) is within an acceptable band.
