Abstract: A brake caliper is provided for a disc brake. The brake caliper has a caliper frame which is designed to extend over an edge of a brake disc and which includes a housing for accommodating an application mechanism for applying the disc brake. The housing has a base plate, an intermediate plate, a housing shell interconnecting the base plate and the intermediate plate, and a housing cover. The caliper frame is cut from sheet metal and shaped and the housing cover is integrally formed with the caliper frame.

Abstract: The invention relates to the use of a composite resin composition comprising (a) at least one polyreactive binder, (b) a first photopolymerization initiator having an absorption maximum at a wavelength of less than 400 nm, (c) a second photopolymerization initiator having an absorption maximum at a wavelength of at least 400 nm and (d) an absorber having an absorption maximum at a wavelength of less than 400 nm, for the stereolithographic production of a dental shaped part based on composite resin. The invention also relates to a process for the stereolithographic production of a dental shaped part and the use of the composite resin composition in this process.

Abstract: Methods for manufacturing a dental restoration for a patient and dental ceramics production devices are disclosed. A dental restoration may be designed based on a scan of the patient's mouth, using a CAD software module. The software module may produce conveyor channels for a positive model based on the dimensions of a muffle in relation to the size and shape of the positive model. The conveyor channels may extend at an angle of between 0° and 130° away from an axis of the pressing channel, the axis being located essentially along an isotherm inside the muffle. A docking site may be selected based on a position with the greatest wall thickness of the positive model. The present disclosure allows the creation of a high-quality dental restoration in a very efficient fashion, in particular when lithium disilicate is used as the dental ceramics material.

Abstract: The invention relates to a method for the construction of a shaped body from photopolymerizable material by using lithography-based generative production, in which a layer of liquid photopolymerizable material is defined on a production platform, and is polymerized in an exposure region having a predetermined contour, a further layer of photopolymerizable material is defined, the layer defined last is polymerized in an exposure region having a predetermined contour for the layer defined last, and the latter two steps are repeated until a shaped body having a predetermined shape has been formed by the sequence of cured layers with contours predetermined layer by layer, each exposure in an exposure region having a predetermined contour being carried out by controlled activation of individual exposure elements in a two-dimensional array of exposure elements, each exposure element being assigned an image element, wherein the exposure of the exposure region is carried out by a common light source and by a two-dime

Abstract: The invention relates to a method for the layered construction of a shaped body made of highly viscous photopolymerizable material.

Abstract: The invention relates to a method for the construction of a shaped body from photopolymerizable material by using lithography-based generative production (rapid prototyping), in which a layer of liquid photopolymerizable material is defined on a production platform (1, 2, 3, 4), the layer is polymerized in an exposure region having a predetermined contour by exposure, a further layer of photopolymerizable material is defined on the polymerized layer, the layer defined last is polymerized by exposure in an exposure region having a predetermined contour for the layer defined last, and the latter two steps are repeated until a shaped body having a predetermined shape has been formed by the sequence of cured layers with contours predetermined layer by layer, wherein ink is applied onto at least one layer inside the predetermined contour, wherein the production platform is suspended moveably and wherein the production platform is brought, after the polymerization of a layer in a processing station for polymerizing

Abstract: A drill bit which is rotatable about a drilling axis is disclosed. The drill bit has a cutting section having one or more cutting segments and a first plug-connecting element and a drill shaft section having a second plug-connecting element. The first plug-connecting element and the second plug-connecting element form a plug connection and the first plug-connecting element and the second plug-connecting element are connectable by a pin connection.
