Agricultural structures for housing livestock and/or agricultural commodity, the structure having a floor that is inclined between first and second walls and a roof that is substantially parallel to the floor. In some aspects, the floor is configured such that a bottom of the first wall is vertically higher than a bottom of the second wall with the bottoms of the first and second walls being level with the underlying ground. In some aspects, a first portion of the floor adjacent to the first wall is at a first elevation, a second portion of the floor adjacent to the second wall is at a second elevation that is vertically lower than the first elevation, and a bottom of the first wall is at a third elevation that is equal to or lower than the first elevation.

A heat dissipating structure for an iron-sheet house includes two frames fixed to left and right sides of a roof. The frames define a ventilation space in communication with an inside of a house including the roof. Each frame includes a hollow interior, at least one lower opening communicating the hollow interior with an outside of the house, and at least one vent communicating the hollow interior with the ventilation space. The frames are interconnected by connecting members. Two adjacent connecting members respectively have two mutually facing grooves. A shielding plate is mounted between two adjacent connecting members and is fixed to upper ends of the frames to cover the ventilation space, with the shielding plate including front and rear ends respectively engaged in the two mutually facing grooves respectively of the two adjacent connecting members and bonded to the two adjacent connecting members by silicon glue.

A structure for sheltering and cooling livestock may include a concrete floored barn having an improved evaporative cooling system. The cooling system may include a misting stack having air inlets, a mixing chamber, and three cooling zones wherein the cooling zones correspond to three different temperature ranges. Each of the cooling zones may include a plurality of nozzles which produce a mist. As air passes through the mixing chamber, the mist may evaporate and cool the air. The cooling system may further include a plurality of large exhaust fans located at an end of the barn distal from the misting stack. The fans may draw the cool air through the barn, over and around the livestock, and out of the barn.

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.

An animal containment and transport assembly for transporting a pet includes a housing and a pair of covers. A top of the housing is open. The covers are hingedly engaged to the housing and are positioned to selectively close the top. The housing and the pair of covers thus define an interior space that can contain an animal. The covers are selectively engageable to the housing so that the covers are fixedly positioned over the top. A plurality of wheels is engaged to a bottom of the housing. A pull handle is engaged to and is selectively extensible from the housing. The pull handle can be grasped in a hand of a user, positioning the user to pull on the pull handle to locomote the housing across a surface.

A lighting assembly includes a light guide having opposite first and second major surfaces and at least one edge surface extending between the first and second major surfaces, a solid-state light source arranged to emit light into the edge surface of the light guide, and a plurality of integrated optical elements associated with the first major surface to redirect the light emitted by the solid-state light source. The lighting assembly may further include an air circulation device and a heat transfer system configured to transfer heat generated by the solid-state lighting source to a flow of air generated by the air circulation device. The solid-state light source may include light-emitting diodes, laser diodes, and/or organic light emitting diodes configured to produce multiple colors. Also provided is a habitat including the lighting assembly, and related methods.

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.

A ceiling vent assembly for use in a ceiling of an animal house. The 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 of the pair of louvers pivots between an open position and a closed position relative the frame. Each louver of the pair 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 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.

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. The first cable is routed from the first louver, around the first vertical pulley, around one of the cable guides and then to one of the control rods, and the second cable is routed from the second louver, around the second vertical pulley, around the other one of the cable guides and then to one of the control rods such that the cables can be selectively routed so that the louvers can be controlled by either one of the control rods.

The present embodiments provide an aviary, a walkway for an aviary, and a walkway system for an aviary. The walkway includes a ramp and at least one support disposed below the ramp.
