The invention provides a panel which is suitable to be used for roofing, side cladding, partitioning, etc., which may be profiled and which is provided with a plurality of apertures dimensioned to permit light to pass through and covered with translucent or transparent material.

A method of absorbing resin into part of a panel of particleboard to provide local strength increases in that part. The method comprises subjecting the part to an electric field, immersing the panel in the resin; and then resubjecting the panel to the electric field to cure the resin. A particleboard panel is also disclosed. The panel has a main body with a specific gravity in the range 0.2 to 0.5 but at least one area on its periphery has a specific gravity in the range 0.7 to 1.0. The one area...

A building panel is disclosed having spaced vertically extending panel studs and vertically spaced laterally extended elongated members fixed to the studs. The panel is suitable to be supported on a wall having spaced brackets with upwardly opened channels adapted to receive the elongated members of the panel. The panels can be erected by installing brackets on a wall and lowering the panels so that the elongated members are received in the upwardly opened channels of the brackets.

In order to eliminate the difficulty in properly shaping the corner of a panel body where the edge portions thereof meet perpendicularly to each other and beautifully finishing the curled portions of a cladding sheet which covers the panel body, the panel 2 comprises a panel body 3 made of sheet metal by plastic deformation of the edge portions of the sheet metal, and a cladding sheet 4 arranged to cover the panel body, with a cutout 35, 36 formed at each corner of the panel body, and a corner m...

A glass panel has a first sheet glass and a second sheet glass which are disposed so that main surfaces thereof are made to face each other, an interlayer film which joins the first sheet glass and the second sheet glass together and an electronic tag disposed between the first sheet glass and the second sheet glass. A shielding layer which interrupts the transmission of light is formed on the first sheet glass. A side of the electronic tag is colored such that an external color of a location wh...

A panel having particular utility in a chair or other apparatus for receiving an occupant in a seated position includes an envelope of resilient material having an opening with a fastener for closing the envelope. An envelope support frame is substantially rigid and formed in a closed loop. The envelope support frame is positioned inside the envelope to tension the resilient material of the envelope in one or more tension zones. A fastener is closed to envelop the envelope support frame with the...

A panel structure for a transport machine is disclosed which is constituted by an integral combination of an outer panel and an inner panel. The inner panel has reinforcing protuberances and recesses, possessing a higher rigidity than the outer panel. The protuberances of the inner panel and a back side of the outer panel are bonded together through insulating layers present on the protuberances.

A novel panel and panel assembly for use in building-type structures, together with panel forming apparatus are disclosed which are especially suitable for using portable, point-of-use, continuously operable, roll-forming techniques. The panel is characterized by upwardly diverging inclined sidewall portions (26, 27), wing portions (28, 29) of substantial lateral extent in relation to an intermediate wall portion that forms the bottom thereof, and centered edge fastening structure (31, 32). This...

A solar panel has a series of channels through which water or other fluids may flow for exposure to and heating by solar radiation. Common to all the channels are inlet and outlet manifolds through which, respectively, the water is directed into and discharged from the channels. Construction of the panel is simplified and is rendered economical by fashioning of the same from a pair of superposed, inexpensive metal sheets, as for example roofing tin. The sheets are readily preformed with the mani...

A building panel in which transverse beam segments bracing primary beams or studs are comprised of particle board. Also disclosed is an assembly of panels in which the panels are coupled by bridging a plurality of transverse beam segments in pairs by means such as respective gang nail plates. Finally, a method of construction entailing an site cutting and assembly of extended panels is described.
