    摘要： A low profile ceiling duct assembly to be used with rooftop air conditioners. The unit combines an octagonal sheet metal ceiling plate which provides the upper portion of a plenum chamber; this extending into the roof space above a ceiling opening. The lower plenum portion is provided by the molded plastic octagonal air distributor box, mounted against the edges of the plate and extending into the room space sufficiently to afford air flow sidewardly outward from the plenum. The air distributor box has outlet grilles at alternate sides of the octagon. They discharge air in four directions along the ceiling line while return air is drawn centrally upward.

    摘要： A chair includes a tubular U-shaped back frame. The back frame defines a pair of spaced apart back legs. A pair of tubular L-shaped side members, each of which defines a front leg and an arm, are connected the back legs. A tubular U-shaped seat frame is connected to each of the front legs and each of the back legs. A connecting member is connected across the seat frame adjacent the connections of the seat frame to the back legs.

    摘要： A seat suspension assembly is disclosed for a bicycle having an upper horizontal frame member. A boom member is pivotally attached at its front end adjacent the front end of the bicycle frame member. A support assembly having a seat mounted adjacent its upper end is connected to the boom member at its rear end. A tension member extends between the boom member and the bicycle frame member for applying a tension force when the bicycle hits a bump to urge the boom toward a position generally horizontal to the horizontal frame member.
