Abstract: Disclosed is a heat exchange conduit formed between pre-fabricated building panels and a daylighting section integral within pre-fabricated, structural panels. The daylighting section has the capability to take ceiling air (or air below free-standing arrays) and either return it to the building during heating months, reject the heat, or shunt it for other uses after being warmed through a dual pane glazing assembly with infrared rejection. During summer days, this allows for dramatic reduction in building cooling demand. Heat exchange surfaces within the conduit are thermally tied to the exterior components of the panels to allow heating by solar insolation or cooling to night sky or air. An advanced insulation system adds to thermal performance and sealed insulation cavities prevent moisture degradation of R-Values. Passage through the heat exchange conduit allows for active whole roof solar collection in spring/fall and night cooling capability during summer night operation.

Abstract: An electricity storage section that stores power from an external power source and supplies the stored power as operating power is provided, and, when an interruption of the external power source to a projection display device is detected, control to reduce the power consumption of a device main body and control to drive an exhaust port shutter so that it is closed by the power supplied from the electricity storage section are performed.

Abstract: A motorized drive system for a louvre assembly of the type containing a surround frame, a pair of spaced apart operating bars positioned within the surround frame and where movement of the operating bars causes rotation of the louvres, the drive system comprising a motor adapted to be positioned within the surround frame, the motor operationally driving a drive shaft which is substantially horizontal when the drive system is fitted within the surround frame, a mounting member which is attached for rotation with the drive shaft, at least two spaced apart attachment points on the mounting member, a first link arm, a second link arm and a third link arm, the first link arm being attached to one of the attachment points and to one said operating bar, the second link arm being attached to another of the attachment points, the third link arm being pivotally attached to the second link arm and to the other operating bar.

Abstract: The present invention 10 discloses a louvered window insert comprising two louvered frame sections 39, 50 each having one vertical member 44, 60 with an upper and lower horizontal member 40, 42, 56, 58 extending from each end thereof and a plurality of louver blades 46, 52 extending horizontally therebetween. The distal ends of the horizontal members and louver blades of the first section have recesses 48, 54 to receive and slidably secure the horizontal members 56, 58 and louver blades 52 of the second section as they travel therethrough allowing a user to size the insert to a window 12 simply by placing the fully overlapped assembly inside an open window 12 and separating the two frame sections 39, 50 thereby reducing the overlap of the horizontal members and the louvers and effectively elongating the insert until the two vertical members 44, 60 are flush to their respective side jambs and then lowering the window 12 until it sits atop the present invention.

Abstract: The Invention aims to provide a ventilation structure capable of interrupting a line of sight from the others while maintaining airflow.

Abstract: An adjustable shutter includes a substantially rectangular shutter frame having first and second pairs of opposed spaced apart frame members 3a, 3b defining a substantially rectangular opening between the frame members. A plurality of substantially parallel louvers 5 are operatively mounted within the shutter opening and extend between the opposed pair of first frame members. The louvers are capable of at least partially occluding the rectangular opening of the shutter frame. A respective frame cover 6a, 6b is operatively affixed to each one of the frame members. An adjustment mechanism is disposed between at least one frame member and its respective frame cover, and is operable to adjust a separation between the frame member and its respective same cover, such that a first overall dimension of the shutter can be adjusted. Finally, a respective corner cover member 7 is disposed in operative relation to each of the frame covers to visually occlude a gap between each adjacent frame cover.

Abstract: A window shutter having a blade assembly which has a non-metallic blade section and an extruded metal mounting section. The metal mounting section is pivotally mounted to the frame and is preferably aluminum or other light materials. In a preferred embodiment, the relative position of the blades to each other and the frame so zero clearance is achieved and in a closed position the blade assemblies overlap to block light. The blade assemblies may be incorporated into a rectangular frame or other style such as a sunburst configuration.

Abstract: A shutter assembly which includes separate top and bottom portions and intermediate slatted portions. The top and bottom portions both include right and left side flanges which include inner and outer channels. Likewise the slatted portion includes a right and left sides which include right and left channels which align with the inner channels on the top and bottom members. Right and left side rails snap fit into the three sections holding them together. The inner wall of the rails snap into the inner channels and the channel in the slatted portion. The inner walls of the side rails include upper arcuate lips that extend over the top edges of the side walls of the top, bottom and slatted sections. The outer wall of each rail includes an L-shaped projection which fits within the outer channels in the flanges. The shutter can be adjusted by removing sections of the slatted portions along pre-formed score lines and then cutting rails to the desired size.

Abstract: An adjustable, fastenerless modular shutter includes end rails having an end wall and a pair of locking portions extending therefrom. The locking portions are slidably receivable in a pair of side rails and engage the side rails to resist separation of the end rails from the side rails during assembly of the shutter. An adjusting member located on the end rail permits adjustable engagement of a shutter panel to the end rail to permit positioning and retention of the shutter panel relative to one of the end rails.

Abstract: A basement vent includes a frame and a screened opening. A plurality of louvers cover said frame. The louvers each include tabs which slide within slots in the frame. The tabs each include a detent section that permit the louvers to be held in an open position for use in the summer months and permit the louvers to be closed during the winter months.
