Abstract: An exhaust diffuser for a gas turbine includes an annular duct. A row of struts is arranged in the duct. In a region downstream of the trailing edges of the struts, the cross-sectional area of the duct decreases to a local minimum and then increases again towards the outlet end of the duct. Thereby the gas flow is locally accelerated downstream of the struts. This stabilizes the boundary layer of the flow in this region and leads to a marked increase in pressure recovery for a wide range of operating conditions.

Abstract: A composite material has a polymeric upper layer which is connected via at least one adhesive layer to a substrate. The substrate is predominantly or entirely formed by an open-cell polyurethane foam onto which the upper layer, containing between 2 and 12 wt % of polysiloxane, is bonded by an adhesive layer. An intermediate layer or a double layer, i.e. a composite of the intermediate layer with a bonding layer located between the substrate and the intermediate layer, is provided between the upper layer and the substrate as the adhesive layer for joining the upper layer and the substrate. The regions of the substrate into which the polyurethane dispersion of the adhesive layer has penetrated in a controlled manner during application have a density which is between 12% and 48%, above the density of the regions of the substrate without the adhesive layer.

Abstract: A coated leather, in particular split cowhide leather, has a preferably nubuck-like appearing surface structure. The coating is formed with a surface layer formed with a mechanically and moisture-stable polymer and bonded to the surface of the leather or split leather by a polymer-based bonding layer. The outer layer is notable for inner smoothness and is formed with soft polyurethane. It includes in the non-embossed region microdepressions which are essentially closed in the direction of the leather but are open towards the outside, have an internal width of less than 130 ?m and are arranged close-packed to each other in the manner of soapy foam cells. The microdepressions are each separately bounded by thin mutually crosslinked stays which have on the outside a matt or finely fibrous fine-roughness structure surface, and have an essentially semispherical-shaped concave inner surface which faces outward and is smooth.
