Publication number: 20240092036Abstract: A pipe fusion machine including a track mounted chassis supporting a horizontal turntable for unlimited, reversible rotation relative to the chassis. A boom pivotally attached at a rear end of, and extending forwardly of, the turntable enables manipulation of elevations and distances of the free end of the boom. The free end of the boom is adapted to permit pivotal mounting thereon of a pipe fusion tool such as an indexer configured to articulate and support a pipe-end facer and a pipe-end heater for respective independent orientation into and out of alignment with the ends of pipes to be fused. A carriage supports fixed and sliding jaws adapted to grip the ends of pipes to be fused for relative reciprocal movement during a pipe fusion process. Each of the jaws may include an upper half jaw and lower left and right quarter jaws.Type: ApplicationFiled: September 20, 2023Publication date: March 21, 2024Inventors: Arthur H. McElroy, II, Paul John Donaldson, Eric R. Abbott, Seth P. Ahrens, Douglas K. Brownell, Gregory A. Ruoff, Jared D. Sparks, Matthew A. Price

Patent number: 6823255Abstract: A system and method for distributing information for storage media, and in particular, for distributing updated navigation data, such as geographical data and navigation application programs, contained on storage media and used in in-vehicle navigation systems. A plurality of local repositories are located in a geographical area. Each of the local repositories includes updated versions of navigation data for the navigation systems. Owners of vehicles having navigation systems may visit any of the repositories from time to time where they can obtain updated versions of the navigation data for their navigation systems. Subscriptions for obtaining updated navigation data would be available to the owners of navigation systems that would entitle them to obtain updated navigation data from the repositories. Procedures for updating the local repositories are also provided. The system and method can be used for updating other types of software.Type: GrantFiled: September 10, 2001Date of Patent: November 23, 2004Assignee: Navteq North America, LLCInventors: John Ahrens, John Jasper, Joseph Kohler, T.
