Abstract: An optical edge guidance system for automatic riveters. The guidance system utilizes a light source which directs light toward the material to be drilled/riveted, a video camera is also directed toward the portion of an object to be drilled/riveted and detects reflected source light from the material. The light from the source directed toward the material is angled about 10 to 15 degrees from the vertical. The material either is marked with a dark stripe or, for example, when the material cross-section is in the shape of a hat section, i.e. an aircraft longeron, a shadow is cast by the light striking the edge of the material and forms a dark area along the longitudinal centerline thereof. The edge of the dark stripe or shadow is detected by the video camera. The video signal from the camera is processed into a voltage equivalent of the video signal. A known reference voltage signal is established when the material positioned properly for drilling/riveting. If this reference voltage signal varies either plus or minus the drill/rivet head is repositioned until the reference voltage is again re-established. The drill/rivet head is moved by means of a servo motor drive controlled by the reference voltage signal which translates the head according to the amount of plus or minus voltage signal from the reference voltage until the exact reference voltage is again achieved for proper drilling/riveting head location.

Abstract: A welding system in which a welder automatically tracks the seam to be welded. This is an automatic servo-driven tracking system employing a raster-scan television camera as an optical sensor. The camera is aimed at the seam area in advance of a cross-slide mounted welding head with the line scan substantially perpendicular to the seam. The camera produces a voltage pulse which exactly coincides with the point in time at which the line scan intercepts the seam. The time incidence pulse is referenced to the standard synchronization pulse (the initiation of the line scan) of the camera. The video signal line which contains these pulses is fed to a novel video anomaly detector. The detector processes this information and produces an output voltage which is analogous to the position of the seam. This output is directed to a master/slave position servo drive system which maintains the welding torch over the seam as the seam moves past the welding station. The image produced by the television camera may be displayed on a conventional television screen together with a line indicative of welding torch position for visual observation of system operation.

Abstract: A linear actuated sealant applicator pump for pumping a sealant into an aperture prior to installation of a fastener in that aperture. An air driven linear actuator translates a cam plate carrying a sealant applicator head from a first position in a first direction spaced from and slightly out of vertical alignment with the aperture to which sealant is to be applied. An adjustable stop limits the translation of the cam plate and injector pump. The actuator then continues in the first direction causing the cam plate to follow a cam slot translating the sealant applicator head in a second direction normal to the first direction toward and in vertical alignment with the aperture with the head engaging the edges of the aperture. The engagement of the head with the edges of the aperture prevents further translation of the sealant applicator head into the aperture. The linear actuator continues to move the cam plate along the cam slot after head and aperture edge engagement causing the cam plate to continue to follow the cam slot resulting in the sealant applicator head being forced to translate upwardly in reverse to the second direction providing a pumping action within the applicator head which pumps a pre-selected amount of sealant from the sealant applicator head into the aperture. The linear actuator when reaching a maximum first direction translation position reverses its direction.

Abstract: An improved back-up tape for use in fusion welding aluminum sheets and structures is disclosed. The tape comprises a small diameter, heavy wall, flexible woven refractory fiber tube within a slightly larger diameter similar tube, both partially flattened against an adhesive coated surface of a wider, heat resistant, strip. In use, the tape is pressed against the back side of a joint to be welded with the adhesive bonding the tape along strips parallel to but slightly spaced from the joint. The joint is fusion welded without the addition of any filler wire. A flat weld underbead, with no molten metal drop-through is produced, with no melting or other significant change in the tape. The tape is then stripped off and the welded structure is ready for use.

Abstract: An improved back-up tape for use in fusion welding metal sheets and structures is disclosed. The tape comprises a rolled refractory fiber fabric partially flattened against an adhesive coated surface of a wider, heat resistant, strip. In use, the tape is pressed against the back side of a joint or other weld line to be welded with the adhesive bonding the tape along strips parallel to but slightly spaced from the weld line and the roll pressed against the joint. Fusion welding is conducted without the addition of any filler wire. A flat weld underbead, with no molten metal drop-through is produced, with no melting or other significant change in the tape. The tape is then stripped off and the welded structure is ready for use.
