Patent number: 11679428Abstract: A connection tube (1) for connecting two tubes (8, 9) of different alloys, wherein the connection tube has a central through-hole extending along a longitudinal axis and comprises a first end portion (2) of a first alloy, a second end portion (3) of a second alloy, and a middle portion (4) which is at least partly double-layered with said second alloy forming an annular inner layer and said first alloy forming an annular outer layer, wherein a metallic bond has been formed between said layers. The inner and outer layers are mechanically interlocked by means of at least one helically extending thread formed in an interface between said layers. The connection tube is manufactured from a base component and an outer component threaded onto the base component to form a work piece, which is hot worked to form a metallic bond.Type: GrantFiled: December 22, 2017Date of Patent: June 20, 2023Assignee: Sandvik Intellectual Property ABInventors: Olle Eriksson, Henrik Häll

Patent number: 11400501Abstract: Herein a tubular element (2) is disclosed. The tubular element comprises a first tubular portion (4) comprising a first metal or alloy and a second tubular portion (6) comprising a second metal or alloy. At least a portion of an interface (9) between the first and second tubular portions (4, 6) extends within a fixed diameter range along a longitudinal direction (L) of the tubular element. The second tubular portion (6) comprises a first end portion (8) arranged around the first tubular portion (4). The second tubular portion (6) comprises a sealing surface (10) extending circumferentially around the second tubular portion (6) at the first end portion (8).Type: GrantFiled: May 13, 2019Date of Patent: August 2, 2022Assignee: AB Sandvik Materials TechnologyInventors: Henrik Häll, Olle Eriksson

Publication number: 20110212773Abstract: A method and apparatus for enabling an electronic game provided by an external game server (202) in a public network (204) and involving multiple players. The players and a plurality of local devices (A,B,C) operated by the players in a local network (200), are registered in a gateway device (GW) connected to the local network. The gateway device then registers the players and devices in the external game server for the electronic game. During the game, the gateway device applies a local game logic and translates any game related messages and/or media communicated between the local devices and the external game server, while communicating with the local devices in the local network using a short-range communication mechanism. As a result, only the gateway device in the local network needs to communicate with the external game server (202) in the public network, which may provide reduced latency in responses to user actions.Type: ApplicationFiled: October 19, 2009Publication date: September 1, 2011Applicant: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Johan Hjelm, Olle Eriksson
