Abstract
Air is detected from opposing ends of a trough-like continuous contour which defines a guide path for the two opposing streams. The air streams will be attached to flow along the trough and where the oppositely directed streams impact or impinge upon each other, they will be deflected normal to their path and the two combined streams will be projected or directed perpendicularly outwardly from the trough in the form of a fan-shaped jet. By controlling the velocity of the two opposing jets, the point of impact or impingement of the two jets can be moved along the trough with the trough defining the path of movement of the point or virtual outlet of outward projection of the combined jets. In preferred embodiments, the defrost and heating and air conditioning outlets for automobiles incorporate the invention so as to avoid protrusions and provide a continuous clean and unbroken appearance.
