Abstract: A refuse container comprising a hollow body with an upper access opening closed by a displaceable cover, and a bag suspension frame, carried by a body wall, said wall movable between a closed position in which the frame is positioned below an access opening, and an open position in which the frame is exposed for bag replacement. The frame has a movable frame element projecting away from the wall. The body has internal surfaces for deflecting the frame element upwardly during closing movement and downwardly during opening movement of the body wall.

Abstract: A air outlet for a passenger compartment of a vehicle has a duct forming a jet of air, a pair of lateral sidewalls, bounded by the top and bottom walls diverging from each other from their upstream ends to their downstream ends at a rate sufficient to preclude a stable wall effect and for causing aperiodic oscillation of the jet into the passenger compartment of said vehicle. Various means are disclosed to further destabilize the wall effect.
