20080220287White Organic Illuminating Diodes (Oleds) Based on Exciplex Double Blue Fluorescent Compounds - The invention relates to an organic white light-emitting diode comprising at least one blue light-emitting fluoranthene derivative of the general formula I as component A09-11-2008
20090096367HETEROLEPTIC TRANSITION METAL-CARBENE COMPLEXES AND THEIR USE IN ORGANIC LIGHT-EMITTING DIODES (OLEDS) - The present invention relates to heteroleptic carbene complexes comprising at least two different carbene ligands, to a process for preparing the heteroleptic carbene complexes, to the use of the heteroleptic carbene complexes in organic light-emitting diodes, to organic light-emitting diodes comprising at least one inventive heteroleptic carbene complex, to a light-emitting layer comprising at least one inventive heteroleptic carbene complex, to organic light-emitting diodes comprising at least one inventive light-emitting layer, and to devices which comprise at least one inventive organic light-emitting diode.04-16-2009
20090165846TRIPLET EMITTER HAVING CONDENSED FIVE-MEMBERED RINGS - The present invention relates to light emitting compounds, especially to triplett emitters suitable for electrooptical applications. Compounds according to the invention are organometallic complexes of a metal, preferably Ir, having a backbone of one five-membered ring that is linked to a five- or six-membered ring, by an intermediate six-membered ring. These compounds are suitable for adaptation to the emission of light in the UV to NIR range by adaptation of atoms or groups within at least one of the five-membered or six-membered ring structures.07-02-2009
20100145050ORTHOGONALLY FIXED COMPOUNDS FOR ELECTROOPTICAL APPLICATIONS - The present invention relates to chemical compounds that can be used in electrooptical applications. The electrically conductive and optical properties of these compounds, e.g. hole transporting, electron transporting and/or light emitting properties can be predetermined by substituting the core structure of these compounds with respective residues. The core structure (06-10-2010

20090233258Method for Producing a Tooth Replacement Having a Multi-Layer Structure - The invention is directed to a method for the production of an individual tooth replacement formed of multiple layers, for example, a removable tooth replacement, implant superstructures, bridges, crowns, partial crowns, onlays and inlays. According to the invention, this object is met by a method for producing a tooth replacement formed of multiple layers in that a CAD data set of the tooth replacement to be produced is initially made by digitizing the teeth which are already prepared and their immediate surroundings into which the tooth replacement is to be inserted, in that a first CAD partial data set and a second CAD partial data set are determined from this CAD data set, the first CAD partial data set representing the supporting framework structure of the tooth replacement and the second CAD partial data set representing the aesthetically and/or functionally relevant outer geometry of the tooth replacement which faces predominantly toward the oral cavity, in that the supporting framework structure is then produced by the first CAD partial data set, and the supporting framework structure for the multilayer tooth replacement is then finished using the second CAD partial data set by applying a functional layer, for example, in the form of a ceramic veneer or a polymer facing the mucous membrane.09-17-2009
20110030423Veneer Ceramic for Dental Restorations and Method for Veneering Dental Restorations - The invention is directed to veneer ceramics for dental restorations of framework ceramics comprising yttrium-stabilized zirconium dioxide. It is the object of the invention to make possible a translucent veneer ceramic which has high flexural strength as well as excellent adhesion to the framework ceramic of yttrium-stabilized zirconium dioxide. According to the invention, this object is met in a veneer ceramic for dental restorations made of yttrium-stabilized zirconium dioxide which is produced from the following components:02-10-2011
20110127001PROCESS FOR PRODUCING IMPLANTS AND COMPONENTS BY DIRECTING SHAPING - The invention relates to a method for producing implants and components by direct shaping. The method includes the steps of producing a mold for the implants or components to be produced, making allowances for changes in geometry occurring during after-treatment after the implants or components are removed from the mold, and, providing partial areas of the mold with a structured surface for transferring this structure to the surfaces of the implants or components. In the method, raw material is introduced into the mold and, after remaining in the mold for a certain period of time, the hardened raw material is then removed from the mold to allow the implants or components to take on the structured surface of the mold as well as its geometry. The demolded implants or components are finally subjected to any after-treatment that may be necessary.06-02-2011
