Patent number: 12503417Abstract: A method of purifying raw methanol obtained in chemical pulping, wherein heavy oil is admixed with the raw methanol to prevent precipitation, and the methanol mixture is distilled or evaporated to recover the methanol. The heavy oil is formed by mixing and heating raw methanol obtained from a side stream of chemical hardwood pulping with an acidic aqueous solution to vaporize low boiling point sulfurous compounds and provide acidified raw methanol. The acidified raw methanol is separated into a liquid top phase, a liquid aqueous middle phase, and a liquid bottom phase. The liquid bottom phase is extracted to obtain the heavy oil.Type: GrantFiled: June 17, 2021Date of Patent: December 23, 2025Assignee: ANDRITZ OYInventor: Johan Olsson

Patent number: 12464041Abstract: Techniques for enhancing performance in Industrial Internet-of-Things (IIoT) scenarios, including techniques for time-sensitive networking (TSN) and 5G wireless network integration. An example method, performed by a wireless device, comprises receiving system information (SI) from a radio base station (RBS) of a radio access network (RAN), the SI being indicative of support for TSN through the RBS, and establishing at least one TSN stream with an external data network, through the RBS. The example method further includes receiving a first timing signal from the wireless communications network, via the RBS, receiving a second timing signal from the external TSN data network to which the wireless device is connected, comparing the first timing signal to the second timing signal to determine an offset, and transmitting the offset to the wireless communications network.Type: GrantFiled: February 13, 2019Date of Patent: November 4, 2025Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Joachim Sachs, Abdulrahman Alabbasi, Mattias Andersson, Niklas Andgart, Ola Angelsmark, José Araújo, Muhammad Ikram Ashraf, Kumar Balachandran, Robert Baldemair, Rodrigo Berg, Yufei Blankenship, Fedor Chernogorov, John Walter Diachina, Torsten Dudda, Henrik Enbuske, Sorour Falahati, János Farkas, Jonas Fröberg Olsson, Majid Gerami, Harald Gustafsson, Kimmo Hiltunen, Andreas Höglund, Torgny Holmberg, Zsolt Kenesi, András Kern, Kittipong Kittichokechai, Anna Larmo, Johan Lundsjö, György Miklós, Hubertus Munz, Gabor Nemeth, Johannes Nygren, Johan Olsson, Alexandros Palaios, Dhruvin Patel, Joakim Persson, Per Persson, Jose Luis Pradas, Sándor Rácz, Pradeepa Ramachandra, Norbert Reider, Dinand Roeland, Stefano Ruffini, Patrik Salmela, Sara Sandberg, Magnus Sandgren, Paul Schliwa-Bertling, Alexey Shapin, Nianshan Shi, Bikramjit Singh, Per Skarin, Bernard Smeets, Ying Sun, Dennis Sundman, Fredrik Svensson, Malgorzata Svensson, Geza Szabo, Wolfgang Tonutti, Balázs Varga, Mårten Wahlström, Kun Wang, Yi-Pin Eric Wang, Osman Nuri Can Yilmaz, Zhenhua Zou, Miguel Lopez
