Abstract: This invention provides a tool for attaching fasteners to a workpiece that includes a slide within a body and a rod threaded into the slide. The outer end of the rod threads into the floating nut of a fastener assembly with an enlargement on the rod centering the nut and the fastener sleeve. The tool includes a die through which the rod extends. A segmented spacer fits around the die to support the workpiece around the opening through it, while the rod, pulled by the slide, draws the fastener sleeve into the opening. The segments of the spacer then are separated and retracted, exposing the die. Further actuation forces the die against the end of the fastener sleeve to flare it outwardly and form a flange for retaining the fastener to the workpiece.

The pipe has closed ends so as to heat the workpiece from both sides uniformly and efficiently. The apparatus employs CW lamps, pulsed lamps, and a combination of the two.

Abstract: Electrically conductive wires, to be connected to multiple terminal connectors and assembled in a wire harness, are prepared for harness assembly by winding individual wires on a reel, cutting each wire to length with both ends of the wire protruding in aligned but opposite directions from the reel, transporting the reel and wound wire by grasping the protruding ends in conveyor mounted clamps, and presenting the wire ends to stripping and terminal attachment machines as the conveyor carries the reel mounted wire. Each piece of wire remains on its individual reel for storage and handling of stacks of reels, and for manipulation of the wire during its placement in a wire harness.

Abstract: A flexible tube-bending mandrel has a longitudinally-split shank link that is unthreaded, but recessed to receive a nut that threadedly engages the bolt for holding the link to a mandrel shank. The mandrel center links are longitudinally split for ease of assembly of their ball-and-socket interconnections and have their socket ends externally threaded to receive an internally-threaded ball segment that holds the center link sections in assembled condition and effectively restrains relative longitudinal motion of the two mating link sections.

The housing and rotating jaw assembly are sealed and provided with bearings therein to permit rotation while enabling passage of fluid through hollow openings therein for enabling lubrication and cooling to permit high speeds of rotation 20 during machining of a work piece supported by the lathe chuck and the apparatus.

Abstract: A nebulizer providing a moistened breathing mixture for inhalation therapy is arranged to flow a gas-liquid mixture in a circular path around the inner surface of a container that is provided with shallow baffle forming ribs extending vertically across the circular flow path to trap relatively large water particles. A heater is detachably connected to the nebulizer discharge fitting and provides additional structure for trapping and removing larger water particles.

Abstract: An X-ray simulator has an X-ray source and collimator connected to the end of a cantilevered horizontal arm mounted on a gantry that rotates about a horizontal axis and extends along a patient supporting table. The horizontal arm has an asymmetrical cross section that causes the arm and therefore the X-ray source and collimator to deflect by differing amounts as the gantry rotates. To compensate for the varying displacement of the X-ray target point and to adjust the position of the target point along the rotation axis of the gantry, the collimator is pivoted in one direction or the other in accordance with the amount of rotation of the gantry axis.

Abstract: A cathode ray tube with a fiber optic faceplate is successively stepped to discrete adjoining areas of a photosensitive film upon which a pattern is to be exposed. The pattern is divided into a plurality of sections, which are exposed upon the film by the cathode ray tube one at a time at its successive positions. In each position of the cathode ray tube, its beam traces a pattern of light upon its faceplate that corresponds to one section of the overall pattern. The pattern of light traced on the faceplate is transmitted directly to the film which is in contact with the fiber optic faceplate.

Abstract: This invention provides a fluid fitting made up of telescoping sleeves providing an annular space therebetween adapted to receive the end of a tube. The outer sleeve is attached to the inner sleeve by being deflected around annular ridges at one end of the inner sleeve. The sleeves are attached to the tube by swaging the outer sleeve so as to grip the tube between the two sleeves. Grooves in the inner sleeve provide corners which dig into the inner surface of the tube and provide seals and retention, while recesses in the outer sleeve receive deflected material of the tube to prevent rotation.

Abstract: A hydraulic press having at least two cylinders adapted for providing relative displacement between the upper and lower platens of a hydraulic press, each cylinder being in fluid communication with only one chamber of a multiple chamber hydraulic system utilizing a common ram operating through all chambers, the ram portion in each chamber having a predetermined ratio of area of the ram in the direction of actuation to volume of hydraulic fluid within its chamber to provide equal find displacement in each chamber or movement of the ram.

Abstract: A scanning laser beam is directed in a circular scanning pattern, perpendicular to the surface of a part that moves across the scan pattern. Reflected light received solely from part edges or other surface discontinuities is compared with a number of preselected threshold levels. When reflection intensity attains any one of the selected threshold levels, an event is triggered, and the beam position at the time of the event, together with the intensity level triggering the event, are recorded, so as to provide information limited to the part edges and other surface discontinuities.

Abstract: Three-dimensional information and a three-dimensional display of the surface of an object is provided by a scanning laser beam mounted on a high-speed rotating disc to repetitively scan across an object transported below the disc upon a moving carrier. Light reflected from the object surface back along the axis of the scanning beam is detected to indicate surface characteristics, such as reflection intensity. Positions of the projected beam in the course of its scanning rotation and of the carrier in the course of its transport motion are detected to generate signals that define the XY position of the scanning beam. Light of the projected energy beam, as reflected from the object at an angle to the beam axis, is imaged by a second lens upon a linear detector array, whereby the position of the image along the linear detector array will indicate elevation of the reflecting area along the axis of the projected beam.

Abstract: This invention provides a captive fastener in which a nut is held to a workpiece by a retainer ring held in a two-piece grommet attached to the workpiece, the retainer ring being flat and split, with its grain perpendicular to a diameter bisecting the split, and its inner and outer edges having alternate elongated recesses to increase the effective ring width without increasing spring force.
