    摘要： This invention is concerned with a stop valve of the type mounted along a fluid carrying pipe, which comprises a closing valve plate hinged about one fixed pin mounted on one internal side of a pipe and operating means for opening and closing the valve plate in the pipe. In accordance with the invention, the operating means consist in at least two articulated links forming an angle lower than 180.degree. therebetween, one of the extremities of said two links being mounted on the valve plate, the other extremity being mounted on the internal side of the pipe opposite to the side where is mounted the hinging pin of the closing valve, and control means extending from said internal side opposite to the side where the hinging pin is mounted to the articulation of the two links, for moving the latter and thus opening or closing the angle formed between the two links. The control means for moving the articulation of the two links preferably consist of a wheel external to the pipe, a shaft carrying a screw being operated by said wheel, said shaft being mounted on the wall of the pipe by a ball-and-socket joint so as to be fixed in translation but not in rotation, and a nut mounted in a movable manner on the screw portion of the shaft and fixed by a yoke to the articulation of the two links.

    摘要： The present invention provides a backdraft damper which is constructed of essentially two integral elements. A damper frame and blades are so formed as to eliminate the necessity of separate hinging elements while providing for pivotal movement of the blades with respect to the damper frame. This pivotal hinging action is free from binding, provides positive sealing in the closed position, and limits the arc of pivotal displacement of the blades to an acute angle. The present invention also provides two novel bearings which may be utilized in combination with the damper to ensure smooth operation in extreme temperature and weather conditions, and to facilitate assembly of the damper frame and blades from non-critical materials.

    摘要： A damper is assembled from a formed frame material having a flange provided with hook-shaped hinge portions formed from the flange and arranged so that when the frame material is folded into the shape of a frame, the hinge portions will be on oppositely positioned sides; and a plurality of blades having complementally configured hook-shaped portions for engagement therewith, by inserting one end of each blade into one complementally configured hook-shaped portion on the flange at one side of the damper frame prior to folding, and then folding the damper frame material about the blades so that the hookshaped portions on the other side of the damper frame engage the other ends of the blades.

    摘要： A louver unit which closes to prevent passage of smoke through air ducts, provided with a fire resistant seal that does not deteriorate at high temperatures. The louver unit includes a housing having an opening in which are mounted two blades, at least one of which is movable relative to the other between an open position and a closed position in which the blades overlap. Fixed to and extending along one of the blades is a resilient sealing strip of heat resistant material such as metal. The strip includes a median portion free to flex away from the blade, which extends around the edge of the blade to which it is attached and projects beyond it towards the other blade. Closing motion brings a free lip of the sealing strip into contact with the other blade in advance of contact between the blades themselves. Further motion to the fully closed position of the blades flexes the sealing strip so that the lip is resiliently biased into sealing contact with the other blade.

    摘要： A multi-blade damper is moved between open and closed positions by pinion gears and racks joined together for conjoint motion. The racks lie on opposite sides of adjacent pinion gears so that movement of the racks causes adjacent blades to rotate in opposite senses.

    摘要： A damper control for an air-conditioning system including opposed walls defined by concentric, cylindrical segments divided transversely into three passageways in each of which is a vane, the vanes being on a shaft concentric with the opposed walls, the vanes also being angularly displaced relative to each other so that, when each vane is positioned intermediate the walls so as to open its passageway, the other two vanes engage the opposed walls to close their passageways, with a heating unit being positioned adjacent one of the passageways to heat the air flowing through it, and a cooling unit being positioned adjacent another of the passageways for cooling the air flowing through that passageway.
