Abstract: 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.

Abstract: 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).

Abstract: Method for manufacturing a composite tube having at least one double-layered portion with an annular outer layer of a first alloy and an annular inner layer of a second alloy provides a base component of the second alloy, having a central through-hole and an externally threaded section, provides an outer component of the first alloy, having an internally threaded section configured to engage with the externally threaded section, forms a tubular work piece by mounting the outer component around the base component such that the internally threaded section is in engagement with the externally threaded section, and hot works the work piece so that a metallic bond is formed between the threaded sections while the mechanical interlock is maintained, and so that the work piece is elongated and its outer diameter is reduced, thus forming a composite tube.

Abstract: A system for assisting a user with searching multimedia objects through one or more search engines is provided. The system includes a collection unit for collecting user information, the user information including at least one of context information associated with a user device and usage information associated with actions taken by a user of the user device, a computation unit for computing statistics based on the collected user information, a reception unit for receiving a multimedia object from a content provider, a creation unit for creating meta-information based on the computed statistics and the received multimedia object, the meta-information used for the one or more search engines to index the received multimedia object, and a response unit for responding the created meta-information to the content provider.

Abstract: 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.

Abstract: A hollow, biological shield assembly capable of surrounding and insulating a nuclear reactor pressure vessel positioned therein. The shield assembly includes a metallic lining attached to a radially inner wall portion of a hollow concrete body, with a layer of thermally insulating material attached to the metallic lining and a plurality of vertical cooling channels also attached to the lining and mounted in recesses formed in the concrete body.
