Abstract: The present invention relates to a synthetic filter material comprising grit, one or more oxides or hydroxides of Fe, La and/or Al, cement, fast-setting binder and water, which can serve as filter material for soil filters for phosphate adsorption, and to a process for producing the filter material.

Abstract: The invention relates to a device and a method for producing layers whose layer thickness distribution can be adjusted in coating systems with horizontally rotating substrate. A very homogeneous or a specific non-homogeneous distribution can be adjusted. The particle loading is also significantly reduced. The service life is significantly higher compared to other methods. Forming of parasitic coatings is reduced.

Abstract: A cooling device for dissipating heat from articles to be cooled, such as power electronic modules, having at least one preferably rigid heat sink which consists in particular of solid material, preferably composed of metal, for example composed of aluminium, and which is intended to absorb heat from one or more articles to be cooled, and having a cooling fluid chamber for accommodating cooling fluid, in particular cooling liquid, to which the heat absorbed by the heat sink can be transferred. The cooling device has at least two preferably rigid heat sinks which consist in particular of solid material and which are connected to one another in an articulated manner, in particular by way of a heat sink joint, in such a way that the two heat sinks are movable relative to one another in different, in particular parallel planes.

Abstract: According to the invention, a device is provided for coating substrates having planar or shaped surfaces by means of magnetron sputtering, by means of which device surfaces having any shape, for examples lenses, aspheres or freeform surfaces which have an adjustable layer-thickness profile, can be coated such that a layer function is maintained on the substantially complete surface. A method for coating substrates having planar or shaped surfaces by means of magnetron sputtering is also provided.

Abstract: The invention relates to a device and a method for producing layers with very good uniformity in coating systems with horizontally rotating substrate guiding. Alternatively, certain layer thickness gradients can be set. The particle loading is also significantly reduced. The service life is much higher compared to other methods. Parasitic coatings are reduced. The coating rate is also increased.

Abstract: The invention relates to an electrically controlled interference colour filter comprising at least two transparent electrodes, at least one nematic liquid crystal layer and alignment layers for alignment of the liquid crystals. When an electrical field is applied the liquid crystals can be realigned and thus the transmission wavelength range of the interference colour filter can be shifted.
