Abstract: Stair elements installed on sloped ground starting bottom up and using a riser reversibly secured with a clamping mechanism. Each riser is attached to a corresponding tread at the time of installation. The manner of fixing the riser to the tread permits the relationship between the two to be adjusted for angle and position.

Abstract: A flexible conduit which utilizes internal spacers and form wires to maintain dimensional integrity during contouring. Once formed into the desired configuration, the system can be made rigid by the injection of pressure into one or more internal elastomeric tubes which expand to solidify the structure. The "fixed" form can then be removed and measurements made for fabricating conforming production pipes and tubes.

Abstract: A pair of jaws, having two sets of mutually perpendicular surfaces which are oriented 45 degrees with respect to the direction of jaw motion. During adjustment the jaws move parallel to each other to accommodate different shank diameters. The opening and closing of the jaws for receiving and clamping a shank is accomplished by an overcenter toggle assembly that produces a combination of parallel and rotational motion which secures the shank against the two mutually orthogonal surfaces of the jaw.

Abstract: Machine leveling device constructed with two bodies (16 and 18) which distance in between can change slightly while maintaining rotational relationship to provide a locking function between the adjusting screw (32) and mounting element (12). The bottom of adjusting screw (32) having convex spherical segment that mates with concave spherical segment of annular disk (38) so that full surface contact is obtained with the mounting surface (40).

Abstract: An array of symmetrically disposed piston-cylinder assemblies may be utilized to produce oppositely directed movements along a single force axis. Plumbing between the various cylinders may be external or internal, or a combination thereof, the exact form depending upon the particular embodiment. The array may be fabricated as a unitized inter/plumbing configuration or from separate cylinders that are functionally retained about an inter/plumbing fixture.

Abstract: A shift travel device, exemplified by a vertical lift arm device, is described which provides for free rotation of its cylinder and arm about its shaft and free travel along the shaft without transfer of twist imposed by the arm and load to its shaft, constant sealing of operating air pressure within the cylinder during operation and load changes, and minimum friction during rotation when the cylinder and arm are in the extreme raised or lowered positions. The device includes unique self-aligning spherical bearings at the ends of the cylinder. The device is useful is a wide variety of environments, including those which are unusually dirty or clean.

Abstract: Automatic crimping apparatus for crimping contacts of different sizes on electrical wires is positioned at the side of a conveyor that moves successive wires to and from alignment with a crimping station which includes a shaker bowl furnishing contacts to a sender station. The sender station sends the contacts one at a time via a pneumatic line through a hollow chuck and collet to seat the barrel end of the contact end upon a contact locating seat that is precisely positioned within a cam operated multi-pin crimper. The contact end receiving seat is apertured and recessed in one end of a funnel assembly and locating structure having a wire receiving and guiding funnel at the other end to define a wire guide path in alignment with the apertured contact end receiving seat. With a contact end positioned on the receiving seat, a portion of the wire receiving barrel of the contact is in the operative region of the crimper, with the other end being firmly grasped in the collet.

Abstract: A contact on the end of a wire is inserted into an aperture of a multi-pin connector by a traveling insertion head that moves in three dimensions to fetch the wire from a wire holder, pull it from the holder and drive it into a selected aperture of the connector. The head moves back toward a wire to insert the wire end contact between a pair of rotating wire drive rollers which grasp the contact and wire to position the contact wholly within a protective insertion quill. The insertion head is then driven into alignment with a selected connector aperture, slightly inserts the quill into the aperture while the contact is fully protected, and the wire drive rollers are rotated to drive the contact and wire through the quill into the connector. A pull test is provided by pivotally retracting the rollers which still grasp the wire. The rollers and quill are withdrawn and opened to enable the rollers and quill to move laterally off the now connected wire to prepare for fetching the next wire.

Abstract: In an apparatus for applying a viscous material, for example, a frit slurry, to a horizontally disposed seal edge surface of the funnel portion of a cathode ray tube through nozzles moved in a closed pattern above such surface, the frit slurry is supplied under pressure from a valved outlet of a container or other source through flexible hoses and then bellows to the nozzles, and the bellows are contracted and expanded in correspondence with the opening and closing, respectively, of the valved outlet.

Abstract: In a conveyor system having a flexible material-supporting belt made up of a plurality of sections connected end to end, there is provided a single, generally channel-shaped track for establishing a selected course of travel for the belt and an arrangement for moving the belt along the track inclusive of a pulling chain and a plurality of roller carriages on rollers affixed to the pulling chain at selected spaced intervals along the chain, the chain and rollers being entirely enclosed inside the track with the track providing entirely inside track surfaces for the rollers. Each roller carriage fastens to the belt and there may be provided a minimum spacing between roller carriages preferably one roller carriage per belt section with a roller carriage attached to each vertical chain link section placing a roller carriage at each pair of abutting ends of each belt section.
