Abstract
A mechanical delivery system for remotely positioning an ultrasonic sensor in mating engagement with a component to be inspected has an elongated support which can be manipulated at a first end from a remote location. A second end has an arm for carrying the sensor. A pin connects the arm to a housing which has an opening therein. A pinion gear is connected to the arm and a mating rack gear is connected to an actuator rod for moving the arm between a first position parallel to and within the housing and a second position wherein that portion of the arm carrying the sensor extends laterally of the housing through the housing's opening. The sensor is mounted on the arm such that it is permitted limited rotation about an axis perpendicular to the arm and limited rocking about a point on that axis thereby enabling the sensor to engage the component as a result of manipulation of the first end of the elongated support despite mispositioning of the second end of the support relative to the component.
