Patent number: 11910931Abstract: It is a feature of a porous body (10, 20) comprising a three-dimensional network of node points (200) joined to one another by struts (100), and a void volume (300) present between the struts (100), that the struts (100) have an average length of ?200 to ?50 mm, the struts (100) have an average thickness of ?100 ?m to ?5 mm, and that the porous body has a compression hardness (40% compression, DIN EN ISO 3386-1: 2010-09) in at least one spatial direction of ?10 to ?100 kPa. The porous body according to the invention combines the advantages of a conventional mattress or cushion with ventilatability which results from its porous structure and is not achievable in conventional foams. The invention further relates to a method of producing such a porous body (10, 20) and to an apparatus comprising said body (10, 20) for supporting and/or bearing a person.Type: GrantFiled: September 8, 2017Date of Patent: February 27, 2024Assignee: Stratasys, Inc.Inventors: Dirk Achten, Thomas Büsgen, Dirk Dijkstra, Nicolas Degiorgio, Roland Wagner, Levent Akbas, Peter Reichert, Jürgen Hättig

Patent number: 10788018Abstract: A wind turbine rotor shaft arrangement, e.g. of horizontal type, comprising a rotor shaft for supporting wind turbine blades, a non-rotating first housing structure for supporting the rotor shaft, and a first rolling bearing arranged to support, in a first axial direction, the rotor shaft in relation to the first housing structure at a first support point. The first rolling bearing is a single row self-aligning bearing comprising an inner ring, an outer ring, and a set of rolling elements formed of rollers arranged in an intermediate configuration between the inner and outer rings. Each roller is a symmetrical bearing roller having a curved raceway-contacting surface arranged contacting a curved inner raceway of the inner ring and a curved outer raceway of the outer ring. A contact angle between each roller and the inner and/or outer raceway is inclined in relation to the radial direction of the rotor shaft.Type: GrantFiled: December 19, 2017Date of Patent: September 29, 2020Assignee: AKTIEBOLAGET SKFInventors: Hans Wendeberg, Håkan Leander, Jürgen Reichert
