An assembly for coupling polyethylene or similar sheeting to a suspended ceiling system to form a temporary curtain barrier. A first component has a pointed shaft configured to pierce through the sheeting, and a pair of opposing jaws configured to grip opposing edges of a T-shaped rail of the ceiling system. A second component is configured to engage the shaft of the first component to lock the first component to the tee and trap the sheeting impaled on the shaft.

In one embodiment, a multiwall sheet can comprise: a first wall; a second wall; an intermediate wall disposed between the first wall and the second wall; a first set of ribs disposed between the first wall and the intermediate wall; a second set of ribs disposed between the second wall and the intermediate wall; a cavity disposed between adjacent ribs; wherein the multiwall sheet is configured to expand and/or collapse when a mechanical force (preferably shear force) is applied to the intermediate wall. Preferably the multiwall sheet has a flexural rigidity of greater than or equal to 10 N/mm.

A dynamic acoustic locking ceiling baffle and a dynamic acoustic locking ceiling system, that includes a single piece of material folded into acoustic locking ceiling baffles, using locking pieces and locking mechanisms, to quickly and easily install the acoustic locking ceiling baffle onto construction ceiling hangers to provide an aesthetically pleasing image, along with a reduction in unwanted noise or room acoustics.

An example of conversion of solar energy into other forms of useful energy is taking heat from an area below a roof and using the heat to generate mechanical energy or electrical power. An air duct opening is placed in a hottest area under the roof. An air fan is placed in the air duct to draw the heated air from the area below the roof. A heat exchanger coil is placed inside the air duct. A return air duct is routed back to the area below the roof. The heat exchanger coil is coupled to a turbine through a closed loop line. A heat transfer medium pump, a first valve and a second valve are retained in the closed loop line. The first valve, second valve and pump are used regulate heat transfer medium into and out of the turbine. An electrical generator may be connected to the turbine.

A ceiling system and a ceiling baffle thereof. The ceiling baffle may include a body portion and at least one locking mechanism. The body portion may have a top edge having a recess that is defined by a floor, a first wall extending from the floor to the top edge, and a second wall extending from the floor to the top edge. The at least one locking mechanism may protrude from the floor of the recess along a longitudinal axis and be spaced apart from the first wall by a first gap and from the second wall by a second gap. The at least one locking mechanism may have a first engagement surface that faces the floor of the recess on a first side of the longitudinal axis and a second engagement surface that faces the floor of the recess on a second side of the longitudinal axis.

A system and method for controlling light shading and thermal insulation in a light transmissive structure is disclosed. An array of adjacently-positioned, inflatable first tubes is provided, each of the first tubes being inflatable to abut an inflated adjacent first tube. Each of an array of inflatable second tubes is nested within, and inflatable independent of, one of the first tubes. Each of the second tubes is connected to one of the first tubes such that when not inflated, each of the second tubes is flattened within the one of the first tubes. When inflated, each of the second tubes abut an inflated adjacent second tube via first tubes. The first tubes are preferably clear, while the second tubes are made of a reflective material.

The present invention relates to a surface forming system intended to be supported by a structural ceiling and/or a wall of a room. The surface forming system comprises a first tile and a second tile, each tile comprising a front major surface, an opposing back major surface and at least one edge surface extending along the perimeter of the tile and connecting the front and back major surfaces, a first connecting member and a second connecting member, each comprising a tile connector and a pivot connector, wherein the tile connector of the first connecting member and the second connecting member are connected to the first tile and the second tile, respectively, and wherein the pivot connector of the first and the second connecting members are pivotably connected to each other such that the tiles are foldable relative each other. The invention further relates to a method for installation of a surface forming system supported by a structural ceiling and/or wall of a room.
