A reinforced storm shutter for protecting doors and windows of buildings from high winds of severe storms and hurricanes. The shutter is comprised of heavy-gauge components, including tubular members having a plurality of aligned, slotted openings and louvers mounted in the aligned openings. The louvers are welded to the tubular members, preferably on the inside surface of the tube, with the weld completely sealing each slotted opening. The tubular members are then welded around the entire periphery of the tube ends to the remaining frame members of the shutter to hermetically seal the tubular members and protect the welds securing the louvers from continuous weathering conditions. The tubular members are formed of mating channel members that are sealingly secured together after the louvers have been welded in place.
A ventilated poppet damper assembly for use in a gas conveying conduit to selectively allow and prevent the flow of gas through the conduit has a movable pair of spaced apart damper plates which define a transverse chamber when in the closed position. The transverse chamber is vented to insure that there is no leakage of conveyed gas past the closed damper plates.
An adjustable tensioning and retaining device particularly well suited for supporting a filter bag in a gas filtering baghouse includes an elongated linking member interconnected to one end of the filter bag, a wedge shaped body member having a sloping top surface with a plurality of spaced apart indentations formed in this sloping top surface, and coupling means for removably connecting the linking member into any of the indentations in the body member. In addition, the wedge shaped body member is mounted to a supporting structure in the filtering baghouse for linear movement such that the plane of the sloping top surface of the body member is inclined to the direction of linear movement.
