  • Patent number: 7837881
    Abstract: A process for continuous purification of a multi-component mixture by means of individual chromatographic columns though which the mixture is fed by means of at least one solvent. The multi-component mixture comprises at least light impurities, an intermediate product, and heavy impurities. The columns are grouped into at least four sections (?, ?, ?, ?) and the fourth section contains three sub-sections (?r, ?f, ?g). The process operates, alternatingly, in a batch-mode position and in an interconnected-mode position. After or within a switch time, the columns are moved in their function in a counter direction to the general direction of flow of the solvent. The combination of batch chromatography with elements of simulated moving bed techniques, or rather, countercurrent-principles, allows for the separation of a true multi-component mixture, even if one of the products is only present in a small amount, comparatively.

  • Patent number: 7777062
    Abstract: B-tris(silylvinyl)borazine is pyrolysed as a borazine precursor for the production of a B/N/C/Si ceramic. A high-temperature ceramic is obtained by means of a further pyrolysis at higher temperatures after a pre-pyrolysis, which is of high purity and essentially free of pores. The ceramic furthermore contains essentially no oxygen and is particularly suitable as a coating material and for the production of heating elements.

  • Publication number: 20090315978
    Abstract: A method for generating a 3D representation of a dynamically changing 3D scene, which includes the steps of: acquiring at least two synchronised video streams (120) from at least two cameras located at different locations and observing the same 3D scene (102); determining camera parameters, which comprise the orientation and zoom setting, for the at least two cameras (103); tracking the movement of objects (310a,b, 312a,b; 330a,b, 331 a,b, 332a,b; 410a,b, 411a,b; 430a,b, 431a,b; 420a,b, 421 a,b) in the at least two video streams (104); determining the identity of the objects in the at least two video streams (105); determining the 3D position of the objects by combining the information from the at least two video streams (106); wherein the step of tracking (104) the movement of objects in the at least two video streams uses position information derived from the 3D position of the objects in one or more earlier instants in time.

  • Publication number: 20090291224
    Abstract: A sheet-like substrate (34) is coated with at least one thin film (36?) composed of at least one porous ceramic layer (S?1, S?2, S?3, . . . ). A solution or a suspension of an organic and/or inorganic metal composite as starting material (14) is admixed with a mixed-in, insoluble pore former (18) and the mixture (22) is sprayed on as layer (S?1, S?2, S?3, . . . ) of a thin film (36). The pore former (18) is at least partly thermally decomposed and/or burnt out to form an at least partly open-pored structure. The process is particularly suitable for producing miniaturized devices such as fuel cells and gas sensors.

  • Patent number: 7601685
    Abstract: Proteins are incorporated into protein or polysaccharide matrices for use in tissue repair, regeneration and/or remodeling and/or drug delivery. The proteins can be incorporated so that they are released by degradation of the matrix, by enzymatic action and/or diffusion. As demonstrated by the examples, one method is to bind heparin to the matrix by either covalent or non-covalent methods, to form a heparin-matrix. The heparin then non-covalently binds heparin-binding growth factors to the protein matrix. Alternatively, a fusion protein can be constructed which contains a crosslinking region such as a factor XIIIa substrate and the native protein sequence. Incorporation of degradable linkages between the matrix and the bioactive factors can be particularly useful when long-term drug delivery is desired, for example in the case of nerve regeneration, where it is desirable to vary the rate of drug release spatially as a function of regeneration, e.g.

  • Publication number: 20090139400
    Abstract: This catalytically active or inactive diffuser is suitable for exhaust gas cleaning systems of internal combustion engines. It consists of a ceramic structure (8) which is obtained from a ceramized polyurethane foam. This ceramic structure (8) can be coated with surface area-increasing and/or oxygen-storing materials and/or noble metals in order to bring about a catalytic action with the gas molecules flowing through it. Because the diffuser is porous in every direction in its interior, a gas and its pressure can spread out equally on all sides through the entire diffuser volume. A virtually homogeneous velocity distribution arises over the entire flow cross section, and increased turbulence is obtained, which leads to more wall contacts of the harmful substance molecules. At the same time, the flow to and through downstream systems over their cross sections with homogeneously mixed exhaust gas including any reactants metered in is more uniform.
