  • ROOM-TEMPERATURE SURFACE WELD REPAIR OF NICKEL-BASE SUPERALLOYS HAVING A NIL-DUCTILITY RANGE
    Publication number: 20020166844
    Abstract: A near-surface defect in a nickel-base superalloy article having a nil-ductility range is weld repaired with a low-power, directional, spatially confined heat source. During the weld repair procedure, the body of the article is maintained at room temperature. Simultaneously, the surface of the article is locally melted in the region of the near-surface defect using the heat source to form a melted region, and thereafter the melted region is allowed to solidify. The heat source produces a shallow weld pool that allows the near-surface defect to be floated to the surface in the case of an inclusion, or welded closed in the case of a surface crack or near-surface void.

  • Identifying egress of nil forward equivalency class (FEC) used for FEC hiding
    Patent number: 11165695
    Abstract: A label switch router (LSR) in a label-switched path (LSP) may receive, from an ingress edge LSR, a Multi-Protocol Label Switching (MPLS) echo request, where the LSP includes a tunnel having details that are hidden by a Nil Forward Equivalency Class (FEC). The LSR may determine whether the LSR is an egress node for the tunnel in the LSP based at least in part on one or more labels in the MPLS echo request. The LSR may, in response to determining that the LSR is the egress node for the tunnel in the LSP, send an MPLS echo reply that indicates the LSR as being the egress node for the tunnel in the LSP.

  • Extruded snap-fastening for slats and metal awning made therewith
    Patent number: 4393629
    Abstract: The upper edge of an awning slat that is suspended obliquely in position is bifurcated into a channel-like structure running along the edge, having inwardly projecting beads on the free edges of the channel. For suspension of the slat, at various places along its length, the beaded channel is forced to spread and snap into notches behind twin barbs of a bracket. Each bracket has parallel ridges bending out from a base to meet the bifurcated grasping webs of the awning slat, the ridges of the bracket being barbed, so as to provide an oblique surface to spread the connecting webs of the awning edge apart until their beads snap into grooves between the barbs and the bracket base. The awning slat with its bifurcated edge is integrally made by extrusion of aluminum alloy and the brackets are relatively short pieces of aluminum alloy extrusions.

  • Welding of nickel-base superalloys having a nil-ductility range
    Patent number: 5897801
    Abstract: An article made of a nickel-base superalloy having a nil-ductility range from the solidus temperature of the alloy to about 600.degree. F. below the solidus temperature is welded, as for example in the weld repair of surface cracks, by removing foreign matter from the area to be welded, first stress relieving the article, adjusting the temperature of the article to a welding temperature of from about 1800.degree. F. to about 2100.degree. F., welding a preselected area in an inert atmosphere at the welding temperature, and second stress relieving the article. Welding is preferably accomplished by striking an arc in the preselected area so as to locally melt the alloy in the preselected area, providing a filler metal having the same composition as the nickel-based superalloy of the article, and feeding the filler metal into the arc so that the filler metal is melted and fused with the article to form a weldment upon solidification.
