  • Gas channeling device for directing blasts of gas through alternative outlet passageways and method therefor
    Patent number: 8001994
    Abstract: A gas channeling device for selectively channeling blasts of gas from an air cannon to various locations comprises a stationary portion and a movable portion. The stationary portion comprises a fluid inlet passageway and at least first and second fluid outlet passageways. The movable portion comprises a fluid channeling passageway, and is pivotally movable about a pivot axis relative to the stationary portion in a manner such that the movable portion can be selectively positioned in alternative first and second positions relative to the stationary portion. The fluid channeling passageway operatively connects the fluid inlet passageway to the first fluid outlet passageway when the movable portion is in the first position. The fluid channeling passageway operatively connects the fluid inlet passageway to the second fluid outlet passageway when the movable portion is in the second position.
