Patent number: 11440081Abstract: The invention concerns a method for feeding an optical cored wire into a molten metal bath and an immersion system and an immersion nozzle to carry out the method. The optical cored wire (6) is decoiled, a feeding and straightening device (4) with a plurality of rollers (20, 21) conducts feeding of the optical cored wire (6) in a feeding direction towards the metal bath (11) as well as a first straightening of the optical cored wire (6), and subsequently a separated further plurality of non-motor driven nozzle straighteners (13) arranged between the feeding and straightening device (4) and the metal bath (11) conducts a second straightening of the optical cored wire (6). Very high precision of temperature measurement can thereby be achieved.Type: GrantFiled: August 24, 2017Date of Patent: September 13, 2022Assignee: HERAEUS ELECTRO-NITE INTERNATIONAL N.V.Inventors: Martin Kendall, Marc Straetemans, Dominique Feytongs

Patent number: 8787340Abstract: A method of connection setup in mobile wireless data communications systems is disclosed where the connection setup time is decreased for delay-sensitive communications sessions relative to the normal connection setup time for confidence-dependent communications sessions. This is achieved by performing some of the connection set-up steps for delay-sensitive communications sessions after successfully demodulating a smaller number of indications identifying an access terminal's desired serving resource than would be demodulated in the case of a confidence-dependent communication session prior to performing the same connection set-up steps.Type: GrantFiled: February 2, 2012Date of Patent: July 22, 2014Assignee: Ericsson ABInventors: Xixian Chen, Vasanta Chivukula, Weigang Li, Guoqiang Xue, Ryan Santa, Miroslav Budic, Brian Troup, Martin Kendall
