Abstract: A ceiling vent assembly incudes a ceiling vent having a pair of opposed end panels and a pair of opposed side panels, which define a frame that is open at its top and bottom. The frame receives two louvers pivotally mounted so as to be movable between open and closed positions. The ceiling vent assembly also includes first and second cables attached to the first and second louvers and a pulley assembly having a pair of vertically-oriented pulleys and a center pulley block having at least one horizontal pulley. The horizontal pulley has two vertically offset cable guides. Control rods pass through aligned rod openings in the end panels and pulley block. The pulley block has cable routing holes adjacent to each of the cable guides.

Abstract: A ceiling vent assembly has a frame that is open at its top and bottom and a pair of louvers pivotably mounted in the frame such that each louver pivots between an open position and a closed position relative to the frame. Each louver has a pivot end, wherein the pivot end is located adjacent to but spaced apart from the pivot end of a second louver of the pair of louvers. The ceiling vent assembly has a sealing mechanism with a flange extending from the pivot end of each louver of the pair of louvers, wherein the flange from the first louver contacts the flange from the second louver in a space between the louvers such that the sealing mechanism reduces the flow of air through the space when the first and second louvers are in either the open or closed positions.

Abstract: A ceiling vent assembly has a frame and a pair of louvers pivotably mounted in the frame such that each of the louvers pivots between an open position and a closed position. Each of the louvers has a pivot end, wherein the pivot end of a first louver of the pair of louvers is located adjacent to but spaced apart from the pivot end of a second louver of the pair of louvers. The ceiling vent has a sealing mechanism positioned in the space between the first and second louvers so as to press on the pivot ends of the first and second louvers such that the sealing mechanism reduces the flow of air through the space. When the first and second louvers pivot between the open and closed positions, the pivot end of the first and second louvers slide relative the sealing mechanism.

Abstract: An assembly for controlling the position of air inlets of an enclosure including an actuation rod which moves laterally and is positioned above and parallel with the air inlets, one or more actuation cables, where the first end of each actuation cable is attached to the actuation rod and the second end of each cable is attached to one or more of the air inlets and lateral movement of the actuation rod causes vertical movement of the actuation cables and attached air inlets.

Abstract: A hinged water valve (26) for use in a watering (38, 46) system (50) of a poultry house includes rigid sight tubes (20) connected with hinged water valves (26). Each hinged valve (26) includes a valve body (28) with a valve cap (30) hinged to the valve body (28) with at least one hinge pin. The valve (26) permits flow of water into the sight tube (20) when the sight tube (10) is in its upright operational condition but prohibits flow of water toward the sight tube (20) when the sight tube (20) is pivoted to a substantially horizontal cleaning condition. An internal plunger (32) interacts with an internal seat (36) of the valve body (28) in a sealing manner. A biasing spring (40) urges the plunger (32) into contact with the internal seat (36) of the valve body (28) but with the valve cap (30) in the upright condition, the stem (50) forces the plunger (32) away from the internal seat (36) opening a flow passage (41).
