Abstract: Disclosed is a modular assembly device for providing adequate and efficient ventilation, temperature control, and insulation in poultry houses. The disclosed invention relates to an automated or manually-operated modular shutter system for tunnel ventilation in poultry houses, the system being self-sealed by the poultry house's internal negative static pressure. All the shutters in a modular shutter unit are designed to open and close in unison by means of specially-designed hinges and hinge spacers. In the preferred embodiment, there are four shutters per modular shutter unit, all of the same construction and dimensions. The shutters are designed with beveled horizontal edges and end cap seals, which together provide an efficient and practically airtight fit against each other when closed. The shutters are also of sufficient thickness to accommodate internal insulation if necessary to raise the insulation values needed for the poultry houses in cold winter months.

Abstract: A panelless shutter is provided, the panelless shutter including a window frame and a plurality of louvers horizontally mounted within the window frame in a parallel configuration, each louver having a first end and a second end. The panelless shutter also includes a louver mechanism comprising a plurality of rotatable members slideably retained within a track and a gear shaft operably coupled to each rotatable member, wherein the rotatable members are coupled to the first end of each louver of the plurality of louvers and the gear shaft rotates each of the plurality of louvers substantially simultaneously. The shutter further includes a louver retainer rotatably securing the second end of each louver of the plurality of louvers, the louver retainer allowing the rotation and vertical sliding of each louver.

Abstract: The invention comprises improvements to transparent/translucent panel systems including two spaced flat panels and a series of elongated, abutting, rotatably mounted transparent/translucent light-controlling members disposed between the panels in which the light-controlling members are at least partially tubular or have annular members along their length to facilitate rotation of the light-controlling members and include a light-blocking surface including improvements to ensure continued efficient operation when the panel systems are subjected to flexure or deflection and possible permanent deformation.

Abstract: A compound shutter system includes a plurality of shutter assemblies. Each of the shutter assemblies has at least one louver operable to selectively open and close the respective shutter assembly. The compound shutter system additionally includes a mechanism operatively connected to each of the plurality of shutter assemblies. The mechanism is also configured to actuate each of the shutter assemblies independently and non-sequentially relative to each other. A vehicle employing the compound shutter system is also disclosed.

Abstract: Light-weight, narrow-profile, bypass sliding shutter systems is disclosed. The shutter system has a dual-track headrail and an inner and outer shutter assembly having louvers. The inner shutter assembly and the outer shutter assembly are configured to move past each other when the louvers in the inner and outer shutters are in a closed position. The shutter systems are lightweight and are for an inside window mount.

Abstract: An active material actuated louver system having an actuator mechanism operable to selectively place a louver or louver system in an open or closed state of operation. The actuator mechanism includes a cable or wire formed from an active material, such as a shape memory alloy.

Abstract: A closing system for refrigeration cabinets comprises a plurality of panels mutually connected two by two and movable along a direction of actuation, between a first position of opening of a compartment of a refrigeration cabinet, whereat the panels are in compact configuration, mutually superposed and laying on planes that are transverse to said direction of actuation, and a second position of closing of the compartment, whereat the panels are in extended configuration, distributed along the direction of actuation. The closing system also comprises at least one element for supporting and guiding the panels and at least one traction device of the panels, to allow their actuation. The closing system can be coupled to each compartment constituting the refrigerating cabinet, to reversibly close access to the products contained within the compartment.

Abstract: A louver type roof structure includes a plurality of elongated parallel slats mounted on slat hinges pivotally supported on carrier beams transverse to the slats. The slats are pivotable between a closed position in which their longitudinal adjacent edges overlap each other, and an open position in which the slats are spaced apart. The slat hinges are mounted to the slats at their lower surface and allow pivoting of the slats between the closed position and an extreme open position by an angle of at least 90°, preferably 110°. The pivoting axis of the slat hinge is disposed substantially under the longitudinal edge of the slat which is overlapped by the adjacent slat. The roof structure may comprise a border slat adapted to be displaced when urged by an adjacent slat when the latter pivots towards its extreme open position.

Abstract: A receiving pit has a grid covering an uppermost opening through which grain or other material is deposited into the pit. The grid including a series of generally parallel and spaced bars and a dust control device according to this invention includes a number of flights each adapted to be positioned beneath the grid. The dust control device includes a number of generally vertically extending bulkheads each adapted to be positioned beneath the grid and juxtaposed to a free end of one of the flights to thereby inhibit the escape of dust from the receiving pit. Each flight includes a series of blades capable of independently deflecting in response to an amount of material deposited through the grid and onto the blade. The dust control device also includes a release mechanism coupled to each of the flights to manually deflect at least selected blades and allow material remaining atop the blade to fall into the receiving pit.

Abstract: A frame member having a centrally disposed opening, a plurality of louvers pivotally disposed within the opening of the frame member, a relief notch on the lateral edge of the louver, and a louver adjusting member attached to the plurality of louvers. The louver adjusting member is completely disposed within the relief notch of the louvers, thereby maintaining at least a flush profile on either the inner surface or outer surface of the window shutter when the louvers are in the closed position. The window shutter apparatus further comprises a hanging strip that includes pivotally attaching the frame member thereto, a compliance strip for attachment to the hanging strip, and a T-strip attached to either the hanging strip or frame member. The compliance strip adjusts for dimensional variations in the side surfaces of the window opening that leave a gap when the hanging strip is placed adjacent thereto.
