Patent number: 10378367Abstract: A wheel disk assembly having a wheel disk, a plurality of blade devices, which are arranged thereon in a manner distributed over the circumference, and a plurality of sealing plates, which are retained in two annular grooves spaced apart from each other radially. In this assembly, the first annular groove is provided in the wheel disk and is bounded axially outward by an annular projection. The projection, in turn, is interrupted by a recess extending in the circumferential direction, with the result that a sealing plate can be inserted axially through the recess between the annular grooves. A closure piece is furthermore provided for closing the recess, which closure piece is captively retained on the sealing plate by a form fit.Type: GrantFiled: July 9, 2015Date of Patent: August 13, 2019Assignee: Siemens AktiengesellschaftInventors: Harald Hoell, Kevin Kampka, Karsten Kolk, Marc Lange, Peter Schröder, Vyacheslav Veitsman

Patent number: 10309234Abstract: Wheel disc arrangement has a wheel disc, a plurality of blade devices fastened along the outer circumference, and a plurality of sealing plates held in two radially spaced-apart annular grooves. The first annular groove is bounded axially outwards by an annular projection. The second annular groove is defined by a plurality of adjacently arranged annular groove segments in the individual blade devices. The first annular groove is of undercut design and has at least two axially opposite and protruding holding projections with a respective bearing surface. The sealing plates have, in the inside diameter, two supporting projections corresponding to the holding projections, axially opposite and face away from one another, with a supporting surface. The arrangement is configured such that the supporting surfaces of the sealing plates are supported against the bearing surfaces of the holding projections under the effect of a centrifugal force.Type: GrantFiled: July 9, 2015Date of Patent: June 4, 2019Assignee: Siemens AktiengesellschaftInventors: Harald Hoell, Kevin Kampka, Karsten Kolk, Marc Lange, Peter Schröder, Vyacheslav Veitsman

Method and system for extracting pairs of multilingual terminology from an aligned multilingual text
Patent number: 6236958Abstract: A terminology extraction system which allows for automatic creation of bilingual terminology has a source text which comprises at least one sequence of source terms, aligned with a target text which also comprises at least one sequence of target terms. A term extractor builds a network from each source and target sequence wherein each node of the network comprises at least one term and such that each combination of source terms is included within one source node and each combination of target terms is included within one target node. The term extractor links each source node with each target node, and through a flow optimization method selects relevant links in the resulting network. Once the term extractor has been run on the entire set of aligned sequences, a term statistics circuit computes an association score for each pair of linked source/target terms, and finally the scored pairs of linked source/target term that are considered relevant bilingual terms are stored in a bilingual terminology database.Type: GrantFiled: May 15, 1998Date of Patent: May 22, 2001Assignee: International Business Machines CorporationInventors: Jean-Marc Lange, Eric Gaussier
