Abstract: An apparatus and method for applying sealant to a countersunk fastener hole. The apparatus includes a sleeve, an adapter tube within the sleeve, a nozzle housing attached to the adapter tube, and a tip within the nozzle housing. A guide pin is attached to the adapter tube and follows an oblique slot in the sleeve. To operate, the sealant applicator is inserted into a countersunk fastener hole, engaging the tip with the countersink of the hole. The tip depresses into the nozzle housing, ejecting sealant onto the countersink. The adapter tube is pushed into the sleeve, moving the guide pin along the oblique slot in the sleeve. This guide pin movement rotates the adapter tube, nozzle housing and tip, causing the tip to uniformly spread the sealant around the countersink.

Abstract: A method and the resulting structure for attaching a doubler to the damaged skin of an airplane, using the original fastener holes, where the fastener countersinks are filled with interference fitted washers and the new fasteners have an interference fit with the airplane skin, doubler and washers.

Abstract: A device for terminating a braided shield to a grounding connector, having a plate that pushes an elastomeric member into the braided shield, pressing the braided shield into the grounding connector, electrically grounding the shield to the connector. The plate and elastomer are attached to a shell, by either a plurality of pins or a retaining ring. The shell has an internal thread that mates with an external thread of the grounding connector, such that when the shell is screwed onto the connector, the plate pushes the elastomeric member into contact with the braided shield, creating an electrical contact between the shield and the grounding connector.

Abstract: A gantry, having a high powered laser, up to 2,000 watts or larger, mounted on a numerically controlled carriage. The gantry is constructed to support and rapidly move the laser, and a laser delivery system, about a work cell, such that the laser is constantly in close proximity to the working area of a workpiece.

Abstract: The present invention is directed to an improved, multi purpose measuring device for determining various parameters of an externally threaded member. In particular, the invention includes a substantially ring shaped housing slidably supporting at least one pair of gage plugs having measuring assemblies mounted thereon. As the gage plugs are selectively moved through the housing to bring the measuring assemblies into contact with an externally threaded member for determining various parameters such as the actual and functional pitch diameters, the minor diameter and the concentricity of the threaded member.

Abstract: A plurality of inlet and outlet channels for receiving and exhausting respectively the flow of a heat exchange medium directed to the inlet channels are located adjacent a plate provided with generally parallel, elongated orifices extending in the direction of and in registration with the inlet and outlet channels. A heat exchange panel is disposed adjacent the plate on the side thereof opposite that of the channels such that the medium entering the input channels travels through the orifices of the plate to the heat exchange panel and then from the panel to and through the outlet channels.

Abstract: A plenum in combination with a heat exchange panel and a panel structure having a large number of closely spaced orifices of equal size. The plenum area relative to that of the orifice area is such that a pressure head in the plenum is maintained to provide a constant flow of heat exchange medium from the plenum through the orifices to the heat exchange panel.
