Abstract: A clamp for electrically connecting a part to be anodized to a conductive bar having a member adapted to attach to the bar and a frame disposed on said member for holding the part to be anodized. Electrical contacts within the frame are forced against the conductive bar and the part to be anodized in the clamped position.

Abstract: A carriage mounted to be driven with a reciprocating motion carries a probe with a stylus and also carries a yoke to move relative to a potentiometer. The unit includes a readily replaceable bushing to permit alignment of the probe in various sizes of holes. A drive unit and a logic circuit controls movement of the carriage.

Abstract: A pneumatic impact gun having an accumulator and interlock system for rapidly dumping a predetermined amount of compressed air into a cylinder to thereby propel an associated piston toward an anvil for contact with a rivet to be upset. The interlock system prevents accidental firing of the gun until a normally open interlock valve is manually depressed. Thereupon, a trigger valve may be manually opened to permit compressed air from a source to open a main valve thereby charging the accumulator to a predetermined condition to allow rapid dumping of compressed air therefrom into contact with the piston. Additionally, a metering valve serves as an energy selector to permit selective charging of the accumulator for varying the resulting impact of the piston onto the anvil.

Abstract: A torque limiting device for preventing the transmission of torque from a drive source to a torque responsive element when a predetermined torque limit has been reached. The device operates by transmitting torque between two axial members having a plurality of balls therebetween with the balls engaged within precisely shaped sockets contained within each axial member. As excess torque occurs, the plurality of balls cause one member to axially displace with respect to the other member and engage a plurality of discs which lock both members, thereby preventing torque transmission.

Abstract: A turntable bearing which is particularly well adapted for securing an adjustable airfoil to the fuselage of an aircraft. The disclosed preferred embodiment comprises a ring shaped structure consisting of a lower support ring, an inner and an outer bearing, a tee ring, and an annular bearing plate. A dovetail groove is placed into the top surface of the support ring around its circumference. Within the groove are the inner and outer bearings with the tee ring located between them. Both bearings and the tee ring engage the top surface of the annular bearing plate which is also within the groove.
