  • Exhaust diffuser for a truck
    Patent number: 8286421
    Abstract: An exhaust diluting and diffusing apparatus includes a pipe mountable on a exhaust stack pipe, and having a flared skirt inlet to define an annular inlet, a mixing section adjacent the inlet, and an exhaust section formed as a pipe section with a multiplicity of holes. The apparatus pipe has a diameter greater than the diameter of the exhaust stack on which it is mounted.
    Type: Grant
    Filed: December 21, 2006
    Date of Patent: October 16, 2012
    Assignee: Volvo Group North America, LLC

  • Exhaust diffuser for a vocational truck
    Patent number: 8006489
    Abstract: An exhaust diffuser for a truck includes a chamber mountable on a truck exhaust stack pipe. The chamber has a cross sectional area much greater than the cross sectional area of the exhaust pipe, and has a dispersing element disposed in the line of exhaust flow to divert exhaust gases laterally into the chamber volume. One or both of the top and front side walls are formed as a mesh or screen to allow the dispersed exhaust gases to flow outward away from the truck cab in a diffused area.

  • Device for determining and maintaining mold gyration angle in a gyratory compactor
    Patent number: 7370574
    Abstract: A gyratory compactor apparatus is provided for interacting with a sample within a generally cylindrical mold having a flange. Such an apparatus comprises a frame defining an axis and an offsetable member engaged with the frame for engaging one end of the mold. The offsetable member is displaceable from the axis and is concurrently movable in an orbital motion thereabout. A pressure ram is movable along the axis and a mold-engaging device is engaged with the frame for receiving the mold such that the mold and frame axes are coaxial. The pressure ram is axially movable within the mold to apply a compaction pressure on the sample, and thereby maintains a portion of the mold at a gyration point along the frame axis. The mold-engaging device axially moves the mold into engagement with the offsetable member.
