Patent number: 10750574Abstract: The invention proposes to introduce a method for a Radio Access Network for providing “Local Switching” between call legs of a call. Within said method the Radio Access Network receives a call identifier for a leg of a call from a Core Network to be handled by the Radio Access Network. The Radio Access Network stores said received call identifier, compares said received call identifier with stored call identifiers for call legs of calls via said Radio Access Network. If said received call identifier matches a stored call identifier the Radio Access Networks establish local switching of call legs identified by the matching call identifier. In an alternative embodiment, the invention proposes to introduce a method for a Core Network for providing local switching for call legs of a call. Within said method the Core Network receives or generates a call identifier for a leg of a call. The Core Network stores said received call identifier and identifies a respective Radio Access Network for said leg of said call.Type: GrantFiled: July 24, 2009Date of Patent: August 18, 2020Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Dirk Kampmann, Karl Hellwig, Philip Hodges, Paul Schliwa-Bertling

Patent number: 9963563Abstract: The embodiments of the present disclosure present systems and methods for the reversible solubilization of (aryl ether ketones) (PAEKs). A thioacetalization process is employed to modify the PAEKs into poly (aryl ether thioacetals) which, unlike PAEKs, are substantially soluble in common solvents. This modification allowing selected analysis techniques to be more easily performed on PAEKs, such as gel permeation chromatography. The thioacetalization may be reversed through a deprotection reaction to recover the original PAEK without substantial degradation, allowing for non-destructive characterization of the PAEK. Advantageously, the thioacetalization process is generally applicable to a broad range of PAEKs, unlike presently known methods of solubilizing PAEKs. Solubilization of PAEKs further expands the utility of the PAEKs, opening up additional routes to chemical modification of PAEKs, as well as allowing for the possibility of processing PAEKs from solution.Type: GrantFiled: October 3, 2017Date of Patent: May 8, 2018Assignee: CYTEC TECHNOLOGY CORP.Inventors: Howard Matthew Colquhoun, Patrick Terence McGrail, Francois Pierre Vincent Paoloni, Philip Hodge, Ioannis Manolakis, Paul Mark Cross

Patent number: 9828478Abstract: A method of forming a polymer matrix composite using a soluble derivative of a poly (aryl ether ketone) (PAEK). The method includes mixing a starting PAEK polymer with a solvent and an acid, said solvent being selected from a group consisting of diethylether, tetrahydrofuran (THF), dioxin, and chlorinated solvents; reacting the PAEK mixture with a Lewis acid and a thiol compound in amounts effective to form a poly (aryl ether thioacetal) compound which comprises at least one thioacetal group; and impregnating a plurality of fibers in a solution comprising said poly (aryl ether thioacetal) compound.Type: GrantFiled: October 8, 2015Date of Patent: November 28, 2017Assignee: CYTEC TECHNOLOGY CORP.Inventors: Howard Matthew Colquhoun, Patrick Terence McGrail, Francois Pierre Vincent Paoloni, Philip Hodge, Ioannis Manolakis, Paul Mark Cross
