  • Patent number: 11351479
    Abstract: A fluid separation apparatus for removing one fluid component from another fluid component in a fluid stream includes an impeller disposed between an annular inlet chamber and a first fluid chamber having a hollow, conical trapezoidal shape with a diameter that reduces along a portion of the length of the first fluid chamber. The impeller redirects a liquid flowing in a circular swirling flow path along the wall of the inlet chamber to an outlet an inlet of the first fluid chamber disposed adjacent the central axis of the first fluid chamber. A coaxially aligned extraction pipe extends into a lighter density fluid envelope formed in the first fluid chamber adjacent the inlet of the first fluid chamber. The extraction pipe may be dynamically adjustable based on the shape of the lighter density fluid envelope to maximize removal of lighter density fluid from the lighter density fluid envelope.

A vortex shield is centered axially within the chamber adjacent to the opening and extends radially from the opening toward the wall. The vortex shield forms a barrier to prevent in the most part, large but light weight particles, carpet fibers and the like from escaping into the exit tube.

  • Patent number: 8133293
    Abstract: An air cleaner suitable for use with a heavy-duty vehicle includes a cylindrical body that can be mounted to the vehicle so that the body is exposed to an air stream when the vehicle moves in a forward direction. The air cleaner has a boattail, which includes a fin attached to a rear portion of the body. The fin has a vertical orientation and extends in a substantially rearward direction from the body. When the vehicle moves in a forward direction, the boattail reduces the amount of low-pressure air located behind the air cleaner.

  • Patent number: 8007554
    Abstract: An air purifier (10) for an animal transport vehicle, such as a horse float (12), has a first air flow passageway (22) for receiving air and directing it in a first direction, and a second air flow passageway (40) continuous with the first air flow passageway and adapted to direct air received from the first air flow passageway in a second direction substantially opposite to the first direction. There is a bend region (42) joining the first and second air flow passageways where the change in the direction of air occurs. An air egress passageway (34) has an opening (36) adjacent the bend region so as to divert some of the air therethrough. The passageway (34) is so configured as to create a venturi effect on the diverted air. A filter (43) is located downstream of the second air flow passageway (40) and is mounted across an opening of the transport vehicle so that air flowing through the second air flow passageway is filtered before entering the transport vehicle.
