Abstract: A contact is bulk fed into the side of a guide block where it is raised up into a crimping head. A sectioned funnel guides wire ends into the positioned contact, after which the sections move apart to permit bottoming of the wires in the contact, and then the contact is crimped to the wire.

Abstract: A stack of strips of feed stock are placed on an adjustable height table. The strips are positioned on the table by arms which align the stack to the centerline of punching dies in a punch press. A pneumatic actuated head uses vacuum cups to raise the end of the top strip and insert it into in-feed rolls. The drive means for the in-feed rolls also drive an encoder which signals roll movement as the rolls incrementally feed the stock into the punch press. Drive means for the feed stock switches to the out-feed rolls once the blanked out stock reaches those rolls, and when the end of the strip passes through the punch press, a control unit is signaled and a new strip is fed into the system.

Abstract: A pressure relief device extends between the double side walls of a passenger compartment of an airplane to communicate with an adjacent cargo compartment. A duct is formed between a perforated section of an inside wall and a panel extending from the inside to the outside wall. A spring closing, pivotally mounted valve extends across to close off the duct and has perforations to permit air flow through the closed valve at low pressure differential between the compartments, but the valve will open at sudden high differential pressures.

Abstract: A U-shaped checking fixture has the legs of a "U" extending vertically upward. A series of measuring probes extend horizontally and laterally inward a measured amount from one of the legs and the ends of the probe define a contour of the skin to be checked. A skin is suspended essentially vertically alongside the measuring probes, another set of matching probes on the other leg of the U-shaped fixture force the skin against the measuring probes and any out of tolerance part of the skin is recorded.

Abstract: An elongated insulating cover of high temperature resistant cloth is impregnated on one side with a fluid sealing high temperature resistant flexible coating, and is covered on the other side with a metallic coating. Fasteners are secured along both sides of the cover; which cover is then overlapped around aircraft flammable fluid lines with the fluid sealing flexible coating on the inside, and the fasteners joined together.

Abstract: A plurality of gimbal mounted wheels are located to protrude slightly above an alignment table to support a work piece. A pair of electro-optical scanners are located above the table to locate a marked bend line on the work piece with respect to a die in an adjacent press brake. The scanner signals for wheel alignment and to drive units located in each half of the alignment table to selectively drive the wheels and move the work piece bend line into position in the press brake. An alternate drive actuates the wheels when the wheels are aligned for maximum rotation.

Abstract: A resin impregnated woven fabric extends the length of a joint with a pair of spaced apart panels intersecting and interwoven with an intermediate laterally extending panel. A reinforcing core extends between the spaced apart panels on one side of the laterally extending panel. Three cores are located on the other side of the laterally extending panel. The intermediate core of the three is located between the two spaced apart panels and is reinforced to provide torsional load resistance. The other two cores are reinforced to provide varying load bearing properties in a spanwise direction.

Abstract: A superplastically formed structure is prepared from a grid patterned core material that is joined to a plate by diffusion bonding or by welding to alternate joint locations on one side and at each of the other joint locations to a plate on the other side of the core. The joined core and plates are then formed by superplastic forming.

Abstract: The blanking tool has a pair of plates, one of which supports a punch and the other has a mating die cavity. The two plates are resiliently joined together to permit limited reciprocal movement. One of the two joined plates has provisions for mounting to a platen of a punch press.

Abstract: A window access assembly sized to contact the inside surface around the periphery of an opening in a sidewall panel and to extend outward through the opening and make sealing contact with an outside structural window. A support member on the backside of the panel provides a pivot surface for rotating the assembly into position where the assembly is fastened to a structural member secured to the backside of the panel.

Abstract: A relief valve has a pair of poppet valves mounted to seal against each other when in the closed position and to uniformly move apart when opening to place one of the poppet valves outside configuration on an aircraft to create a ram air effect through the opened valve.

Abstract: A pair of feeder bowls are placed one above the other to simultaneously feed two different types of wire contacts onto two different tracks, and into separate alignment openings in a guide block. A pivotally mounted crimper is selectively moved to position the crimper head over the selected alignment opening. A rod extending from the crimper automatically positions a selector bar to actuate a plunger rod to move the selected contact into position to be crimped.

Abstract: A graphite containing composite structure having a fastener area for joining the composite to other structures terminates the graphite reinforced laminate adjacent to the fastener area. Kevlar reinforced laminates abut the graphite laminate and extend over the fastener area and are further reinforced with Kevlar laminates that overlap the graphite then extend over the fastener area.

Abstract: A ball joint has a flange and nut with matching spherical surfaces in the seal area of the joint. A frusto-conical wear ring seals between the matching surfaces with an inner and an outer line of contact between the ring and the surfaces to provide a spring type seal.

Abstract: A composite structure has joints reinforced with adherend inserts between skin and web. The inserts are wedge shaped, have laminated sides with reinforcement in two directions, a reinforced core and the laminates are stitched together adjacent the core.

Abstract: A flat sheet metal part is shot peened on both sides with an intensity programmed to vary in a pattern for imparting localized growth matching the part to a spanwise curvature of a contoured aircraft wing. The part is shot peened on one side with an intensity programmed to vary in a pattern for matching the part to a chordwise curvature, and the part takes on the compound curvature of an aircraft wing surface.

Abstract: A multiplicity of abrading discs are individually mounted in an abrading head. The discs are each self-aligning for following the contour of the surface to be abraded. The discs are rotated to abrade the surface and a multiplicity of openings in the head permit debris, generated by the discs, to be removed from the work by a vacuum source attached to the head.

Abstract: A filler of polyisobutylene dissolved in a solvent is combined with boron nitride to form a stop-off compound used as a parting agent when diffusion bonding metals. A uniform coating of the compound is applied with screen printing methods prior to bonding.

Abstract: An anvil having a working end away from a mounting shank, has compressed air flowing through the anvil to feed outward to the working end. An insert fastened to a panel is secured to the panel by forming on one end of the insert and by bonding with an adhesive on the other end. The working end of the anvil presses against the insert during forming and the flowing compressed air blows excess adhesive from the contacted surface of the insert.
