    Abstract: The cylinder may be an aircraft landing gear axle. The items may be pick- to sense axle deformation. A ring (30) for supporting the pick-ups is made of highly resilient material. It is initially of such a size that its cylinder-engaging surface overlaps the cylindrical surface it is to engage. The ring is then deformed by urging at least two points (34 to 37) around its circumference to increase the degree of overlap. While maintaining the deforming force on the ring, its cylinder-engaging surface (31) is machined so that there is no longer any overlap, and still maintaining the force, the ring is engaged with the cylinder. The force is then removed. The said points move resiliently away from the cylinder, but intermediate points are consequently resiliently urged into contact with the cylinder. The contact is smooth and progressive, thus avoiding the kind of stress concentrations that could reduce cylinder life by fatigue, etc.

  • Patent number: 4630350
    Abstract: A method for making flexible, corrugated rubber tubing with internal reinforcement. An extruded sleeve of uncured rubber is slid axially onto an elongated internal forming member, after which an external forming means is placed around the assembled sleeve and used to form corrugations. The resulting product is heat-treated to set the corrugations and thus to form a flexible corrugated tube length. A helix formed of flexible, resilient wire rod is pulled through the corrugated tubing in an axial direction and simultaneously rotated in a direction to thread the helical rod into the internal helical groove in the corrugated product. At the same time, the helix is axially extended to reduce its helix diameter. When the helix has been completely extended through the corrugated tubing, it is released to that it expands radially into tight conformance with the internal helical groove.

  • Patent number: 4610834
    Abstract: A tool for installing a corrosion barrier ring into its groove behind the threads of a tapered box end comprises a tapered metallic liner for covering the threads and a suitable mandrel for carrying the ring to its location through the liner. A suitable seating tool may be used for the final seating of the ring in the groove. The tip is notched to permit axial deformation of the ring, but not appreciable radial deformation, so as to allow the ring to be positioned to the location of the groove. The tip of the mandrel is sized to prevent the ring from sliding over the mandrel as the mandrel is pushed through the liner. Rotating the mandrel starts the ring into the groove by straightening out the ring deformations and permits removal of the mandrel and the liner. The seating tool is then subsequently used for the final seating of the ring in its groove. Stacked tip pieces permit adjusting the contour and size of the seating tool tip to accommodate to a variety of ring shapes and sizes.
