An automobile interior trim component includes a molded substrate laminated onto a cover sheet including a foam backing and a skin film having a surface texture. The cover sheet is preheated so the skin film is in a melted viscous liquid state above its melting temperature, and the foam backing remains in a solid elastic foam state below its melting temperature. The preheated cover sheet is mechanically pre-molded by a back mold into a front mold. Pressurized air is applied through the back mold, to blow-mold the cover sheet against the front mold, so the melted skin film reproduces a surface texture of the front mold surface while the solid foam backing acts as a buffer and air barrier layer. Vacuum is applied through the front mold surface. The mold is opened, a substrate is introduced, and the back mold then molds and thermally laminates the substrate against the foam backing of the cover sheet.

A spray applied building construction coating material forms a waterproofing, water vapor permeable, air barrier, building wrap coating layer between an exterior facing surface of a building sheathing layer and an interior facing surface of an exterior building cladding layer. A building construction assembly is formed by spray coating the exterior surface of the sheathing layer with the coating material or by spray coating gaps in the sheathing layer with the coating material and spray coating the exterior surface of the sheathing layer and previously coated gaps in the sheathing layer with a second coat of the coating material and applying an exterior cladding layer over the coating layer(s).

A device inhibits oxidation of wine remaining in a bottle. A stopper and an inflatable bladder replace the cork. In a first embodiment, a wine duct formed in the stopper is open when the stopper is in an extended position and is closed when the stopper is retracted. Air displaces but does not contact the wine by filling the bladder through an air duct formed in the stopper. After decanting, air that seeps into the wine chamber is removed by forcing air into the bladder, using an external hand pump inserted into the air duct. When sufficient air is pumped into the bladder to raise the wine level to contact the stopper, the stopper is placed into its retracted position. In an additional embodiment, a valve controls opening and closing of the wine duct and the stopper has no extended and retracted position.
