20140151854 | Method for Separating a Layer and a Chip Formed on a Layer - A method for separating a layer from a substrate. The method includes providing a plurality of trenches extending from a first main surface of the substrate into the substrate. A heat treatment of the substrate is performed such that edges of the trenches grow together at the first main surface to form a closed layer at the first main surface, wherein lower portions of the trenches form one or more cavities within the substrate. After that the closed layer is separated from the substrate along the one or more cavities. | 06-05-2014 |

20150151388 | STIRRER ORGAN IN COMPOSITE CONSTRUCTION - The invention relates to a stirrer organ in composite construction comprised of a metallic part and a hybrid casting, with the hybrid casting being fixed to the metallic part by means of at least one anchoring element which forms at least one back-cutting in the hybrid casting. Furthermore, the present invention relates to a method for rehabilitating a damaged metallic stirrer organ which when applied provides a rehabilitated stirrer organ in composite construction. The invention tackles the task of creating a stirrer organ in hybrid construction which features a largest possible metallic part because higher strength can hereby be achieved. This task is inventively solved in that the anchoring element is provided with a perforated plate which is spot-wise fastened to the metallic part and which is arranged at least partly at a small distance to the surface of the metallic part so as to configure the at least one back-cutting. | 06-04-2015 |
