Abstract: Disclosed are methods and apparatus for providing pre-assembled modular structural louvered systems that include structural supports and louvers, and may also include dampers, actuators and wiring in pre-assembled modules that may be transported to a building site, tilted up into place, and installed. Embodiments of the present invention also provide methods and apparatus for providing pre-assembled modular structural louvered systems which include integrated vertical and horizontal structural supports, allowing for the elimination of some vertical and horizontal wall structures in a building by relying on the structural support provided in the modular louvered systems, thereby making more space available in the building for louvers and airflow.

Abstract: Outflow valve (OFV) assemblies including non-metallic frames and enhanced attachment features are provided. In embodiments, the OFV assembly includes a non-metallic frame to which at least one valve door is pivotally mounted. The non-metallic frame may, in turn, include a generally rectangular frame body, a central opening through the frame body, an outer peripheral flange extending around at least a portion of the frame body. Frame attachment interfaces are distributed or spaced around the outer peripheral flange of the non-metallic frame. The frame attachment interfaces include fastener openings and elevated platform regions, which project from an inboard side of the outer peripheral flange and through which the fastener openings extend. Base plates seat against the elevated platform regions. Fasteners engage the base plates and extend through the fastener openings to an outboard side of the outer peripheral flange to attach the OFV assembly to an aircraft fuselage.

Abstract: An air register including a body having a front plate with a front surface, a rear surface, and at least one opening extending from the front surface to the rear surface, an upper air dam having a leading edge and a trailing edge, a lower air dam having a leading edge and a trailing edge, an air flow control mechanism operatively connected to the upper air dam or the lower air dam rotate both the upper air dam and the lower air dam simultaneously, and wherein the upper air dam and the lower air dam rotate in opposite directions upon operation of the air flow control mechanism.

Abstract: A damper, comprising a plurality of blades, a plurality of blade arms, each blade arm coupled to one of the plurality of blades and a motor coupled to one of the blades and one of the blade arms.

Abstract: An air outlet assembly comprises an air housing for air flowing through; a retainer connected to the air housing; a plurality of vanes disposed on the retainer, spaced apart each other and rotatably connected to the retainer; and a sliding link. The sliding link is disposed on an inner surface of the air housing, adjacent to the retainer, coupled with each of the vanes and configured to be slidable on the inner surface so as to orient each of the vanes relative to the air housing.

Abstract: An airflow outlet is provided. The airflow outlet comprises at least a first housing, a second housing, a first shut-off door, a second shut-off door, and a control apparatus. The first housing defines an outlet opening and the second housing defines an inlet opening. The first housing and the second housing are operatively coupled and define a substantially closed airflow path between the inlet opening and the outlet opening. The first shut-off door is coupled to the second housing and rotatable about a first axis. The second shut-off door is coupled to the second housing and rotatable about a second axis. The first shut-off door and the second shut-off door are operatively configured to meter a flow of air through the inlet opening by occupying a selectable operating position. The control apparatus is configured to control the selectable operating position of the first shut-off door and the second shut-off door.

Abstract: A system for directing the flow of a fluid and controlling the rate of flow of the fluid. The system comprises a channel for directing the flow of the fluid; at least a pair of articulating vanes positioned within the channel for controlling the flow rate of the fluid within the channel; and a linkage between the vanes coupling the articulation of each of the vanes to the other of the vanes, wherein each vane imparts a force on the linkage when the relative angle of attack is greater than zero, wherein the force imparted on the linkage by one of the vanes is at least partially cancelled by the force imparted on the linkage by the other of the vanes during the articulation of the vanes.

Abstract: Provided is a wing knob adjusting device for an air vent, including a housing mounted with an air discharge part, a front wing mounted in the air discharge part, a rear wing mounted in front of the front wing, and an actuator vertically rotating the front wing or the horizontally rotating the rear wing, wherein the actuator includes fixing members mounted at top and bottom portions of the air discharge part, respectively, a knob link of which the top portion may be upwardly inserted into the fixing member, the bottom portion may be vertically coupled rotatably with the front wing, and the center may be horizontally coupled rotatably with the rear wing, an actuating knob slidably mounted in the rear wing to rotate the knob link vertically or horizontally, and a connecting rod connecting the knob link with the actuating knob so as to interconnect them.

Abstract: A low cost air damper that provides a good seal with low torque requirements. Blade seals of square cross sectional configuration are provided on each damper blade so that the blade seals engage adjacent blades before the blades are fully closed. L-shaped side seals and multiple discs that receive the ends of the blades serve collectively to seal between sides of the damper frame and the blades when the blades are closed even when the blades are not cut precisely. One edge of the L-shaped side seals engages and seals against the discs and the other edge of the side seals laps over and seals against a flat side of the blades and against the square blade seals. A low friction coating is applied to the side seals to further reduce friction.

Abstract: A faucet includes an annular body (101), a throttle valve (102) constituting a seat and an annular metal gasket positioned therebetween while being accommodated in a recess, the movable sealing element being connected by a plate to a static sealing element gripped within the recess, the plate is flexible and there is play between the recess and the part of the main surfaces of the dynamic sealing element closest to the seat (102) when said element is remote from the seat (102).

Abstract: A bypass valve has a body with an inlet for receiving untreated water, an untreated water outlet for connection to a water treatment apparatus, a treated water inlet and an outlet through which treated water flows. The body includes a first valve seat between the inlet and the outlet, a second valve seat between the treated water inlet and the outlet, and a third valve seat in a flow path between the inlet and the outlet. A set of first, second and third flapper valve elements selectively engage and disengage the first, second and third valve seats respectively. The three flapper valve elements are preferably connected to a common manually operable actuator which can be latched to hold the valve elements in different functional positions.
