Patent number: 11752552Abstract: A method for building structures on existing components includes preparing an auxiliary plate suitable for fastening on the working plate, wherein the auxiliary plate has at least one reference marking, fastening the component on the auxiliary plate, optionally processing the at least one surface to be processed for providing a surface that is substantially parallel to the working plane of the device, measuring the at least one reference marking and the component, wherein the position is recorded, introducing the auxiliary plate with the at least one reference marking and the component into the device and detachably fastening the auxiliary plate on the working plate and processing the component in the device for additive manufacturing by working data on the basis of measuring data. A device and a composite structure for additive manufacturing is used in the method.Type: GrantFiled: October 9, 2018Date of Patent: September 12, 2023Assignee: SIEMENS ENERGY GLOBAL GMBH & CO.

Patent number: 10844747Abstract: A continuous flow machine has at least one annular guide vane carrier. The guide vane carrier, formed at least by a lower part and an upper part detachably connected to same, has at least three guide vane stages retained on the inner circumference of the at least one guide vane carrier, arranged axially behind one another in the flow direction and each having a plurality of radially extending guide vanes. Each of the guide vanes also has a guide vane blade, a base plate and a top plate, wherein the guide vane blade extends between the base plate and top plate. Via the arrangement of the securing pin in an intermediate space accessible in the assembled state, a partial disassembly of the individual guide vane stages is possible, independent of the remaining guide vane stages. The guide vane stages are conventionally mounted via retaining protrusions on neighbouring guide vane stages.Type: GrantFiled: February 14, 2017Date of Patent: November 24, 2020Assignee: Siemens AktiengesellschaftInventors: Stefan Bärow, Oliver Dominka, Guido Ederer, Christian Felsmann, Florian Fuchs, Robert Herfurth, Jose Angel Hernandez Maza, Michael Kluck, Eike Kohlhoff, Kay Krabiell, Khaled Maiz, Behnam Nouri, Andre Willmann
