Abstract: A seat assembly having a headrest for supporting the head of a seat occupant. The seat assembly includes a seat back, a support post disposed on the seat back, and a headrest. The headrest has a front portion for supporting the head of a seat occupant. The front portion is configured to move between a first position and a second position. The headrest is rotatably disposed on the support post such that the headrest can rotate independent of movement of the front portion.

Abstract: The invention relates to a method for photocatalytic separation of a dispersed substance from a surfactant-containing dispersion. The surfactant-containing dispersion contains at least one dispersant, one dispersed substance, one surfactant and one photocatalyst. Irradiation of the photocalyst causes the decomposition or modification of the surfactant allowing for the separation of the dispersed substance from the dispersant.

Abstract: Surface coating having a bright appearance on motor vehicle wheels made of light metal alloy castings or steel, which can comprise a plurality of layers, wherein it has at least one first layer composed of aluminum or aluminum alloy which is applied directly to the wheel surface, which has metallic brightness, and a method for producing a resistant bright coating on aluminum alloy or steel surfaces, which comprises the steps gas-phase deposition of aluminum or Al alloy to form a first dense and bright coating electrochemical oxidation of the surface of the first layer and formation of a nanoporous to microporous second layer of aluminum oxide having a thickness in the range from 50 to 1000 nm.

Abstract: A method for cleaning, method and device for the application of a protective medium to a turbine blade, and a method for placing cooling bores in a turbine blade is disclosed. For this purpose, hot supercritical carbon dioxide is used as a tempering and/or cleaning medium and compressed and decompressed one or more successive times. The cleaning medium is decompressed to a pressure at which the gas assumes a volume that is a multiple of the volume of the compressed cleaning medium in the pressure tank. In so doing, it is possible to remove particulate and other impurities, even from recesses, blind holes, or open hollow spaces.

Abstract: The invention relates to electroconductive layered paper with a layer structure consisting of at least one first, one second and one third layer, comprising at least one electroconductive material in the form of carbon fibres. Said first, second and third layers are produced or deposited one after the other in an air stream, using the airlaid technique. The carbon fibres lie predominantly in the plane of the layer in the first layer (1), increasingly at a slant and/or increasingly perpendicular to the plane of the layer in the second layer (2) and are located on top of the second layer in the third layer (3) in a ground form. The invention also relates to a method for producing electroconductive layered paper and to its use as a gas diffusion electrode in polymer electrolyte membrane fuel cells.

Abstract: A method of operating a milling bath wherein a metal workpiece to be milled is immersed in a milling bath containing a milling medium, the metal oxidizing owing to a chemical reaction between the metal and milling medium and being transformed into a soluble complex. The resultant mixture is subjected to a separation process which separates the excess milling medium from the complex, the recovered milling medium being used for the further operation of milling baths and the complex being subjected to a preparation process. A mixture of dissolved complexed metallic ions and milling medium is removed from the milling bath at a concentration of dissolved complexed metallic ions which is far below the saturation limit thereof. The separation process is a nanofiltration process in which the milling medium is separated from the mixture according to the principle of reverse osmosis, the residue simultaneously being concentrated with complexed metallic ions.

Abstract: A method for cleaning objects (4) in a pressure tank (2) using a compressed clean fluid, which contains a gas and which is compressed and decompressed one or more times. According to the present invention, the cleaning fluid is decompressed to a pressure at which the gas has a volume that is a multiple of the volume of the compressed cleaning fluid in the pressure tank. In this manner, it is possible to remove particle-sized and other impurities from recesses, blind holes, or open cavities (6) in the objects.
