Patent number: 9318685Abstract: The invention relates to a method for producing a superconductive element to be used as a wire-in-channel superconductor in magnetic resonance imaging (MRI) and in nuclear magnetic resonance (NMR) applications, which superconductive element contains a superconductive wire and a copper component having a longitudinal groove and the superconductive wire being positioned in the groove. In order to produce the wire-in-channel superconductive element by a mechanical contact between the superconductive wire and a wall of the groove in the copper component, at least one contact surface is coated with a lead free solder material before having the mechanical contact. In order to enhance the thermal and electrical conduction and to create a bond between the said components the soldering material is fused in annealing process step.Type: GrantFiled: May 11, 2006Date of Patent: April 19, 2016Assignee: Luvata Espoo OyInventor: Jukka Somerkoski

Publication number: 20150030495Abstract: A pivotable tundish (1) for continuous casting a metal alloy. The tundish comprises a body (3) comprising a first chamber (5), a second chamber (7), a first passage (12) between the first chamber and the second chamber, and a second passage (16) between the second chamber and a mold (9). The first chamber is adapted to receive and hold a base metal constituting the base for forming the metal alloy by addition of alloying elements. The metal alloy is fed from the second chamber to the mold through the second passage. The second chamber further comprises a first portion (30) and a second portion (32), and a third passage (36) between the first portion and the second portion. In the casting state the metal alloy is formed while casting by adding the alloying elements to the second portion of the second chamber.Type: ApplicationFiled: February 10, 2012Publication date: January 29, 2015Applicant: Luvata Espoo OyInventor: Sarita Hernesniemi

Patent number: 8388768Abstract: The present invention relates to a method for preparing an artificial patination material to substrates, preferably made from copper or copper alloys and a patination material. The raw material is a copper salt, which reacts with an alkali metal hydroxide. The precipitate is dispersed with powerful mixing and an addition of a dispersing agent. An oxidative agent like manganese dioxide is used, and carbon is used as an agent for catalyzing natural patina forming. Metal compounds are used to achieving desired color and/or color tinge. The invention relates also to the corresponding patination material.Type: GrantFiled: April 7, 2003Date of Patent: March 5, 2013Assignee: Luvata Espoo OyInventor: Tapio Korpinen
