    Abstract: Providing a network service is disclosed. A data associated with the service is received. It is determined whether a local context associated with the service is in an active state with respect to the service. The data is redirected to another chassis, via an inter-chassis backup connection, if it is determined that the local context is not in an active state with respect to the service.

  • High temperature tubing joint with threaded, split collar
    Patent number: 5152556
    Abstract: A connector system for joining a male tube to a female tube comprises an axially-split nut which extends across the region being joined. The female tube is externally threaded and mates with internal threads on one end of the axially-split nut. A shoulder formed in the other end of the axially-split nut engages a retaining ring formed on the male tube. A compressible seal ring is disposed between the end of the female tube and a second shoulder of the retaining ring. An external nut is placed over the axially-split nut to hold the entire assembly together and provide a radially compressive force on the seal ring. An axially compressive force can be provided by turning the female tube to draw the female and male tubes closer together.
