  • Patent number: 9555901
    Abstract: A method of protecting a part of a surface of an aircraft against contamination with insect residues and/or against icing is described. The method includes the following steps: a) coating the part of the surface to be protected with a coating that can, within a period of ?3 hours from take-off of the aircraft and in normal flying conditions, reduce the adhesion to the part of the surface to be protected until detachment occurs on the basis of (i) temperature change and/or (ii) UV radiation and/or (iii) addition of a decomposing component and/or (iv) difference in air humidity, and b) exposing the part of the surface to be protected to (i) a temperature change and/or (ii) UV irradiation (iii) and/or addition of a decomposing component and/or (iv) a difference in air humidity, so that the coating together with any contaminants and/or icing thereon detaches.

  • Patent number: 8173522
    Abstract: A process and an apparatus are described for the treatment of wafers, in particular for the thinning of wafers. A wafer with a carrier layer and an interlayer arranged between the carrier layer and the wafer is also described, in which the interlayer is a plasmapolymeric layer that adheres to the wafer and adheres more strongly to the carrier layer than to the wafer.

  • Patent number: 7736570
    Abstract: A tool is described for generating a microstructured surface, comprising: a flexible matrix with a negative of the microstructure to be generated a pressure roller driveable over a surface, for pressing the matrix onto the surface, in which the pressure roller and matrix are arranged so that when the roller passes over the surface the matrix executes a rolling movement between the roller and layer, so that the negative of the matrix faces towards the surface, and a device for accelerating the curing of a curable material is arranged so that when the pressure roller passes over the surface it accompanies its movement and acts on a part of the surface.

  • Publication number: 20090075058
    Abstract: The use of a lacquer is described, comprising a polyurethane matrix based on aliphatic components and fillers which are embedded in the polyurethane matrix and increase the resistance to abrasion as an abrasion-resistant coating of (a) aircraft landing flaps 2 in the contact region with the spoilers 4 or (b) in the abrasion region of the cargo doors or (c) in the abrasion region of other aircraft parts mechanically rubbing on one another during operation. Corresponding landing flaps and lacquers are also described.

  • Publication number: 20080032136
    Abstract: The invention relates to a product (11) with a laminated system (13; 15) consisting of at least one covering layer (15) and a moulding layer (13) arranged between the covering layer (15) and the product (11), wherein the moulding layer (13) is a plasma-polymeric layer that moulds the contours of the product (11) and adheres more firmly to the covering layer (15) than to the product (11). It further relates to a process for producing such a product (11) with a laminated system and to a process for producing a moulding negative and to a process for producing a positive model of (i) parts of the surface or (ii) the surface of a product.
