Patent number: 8314169Abstract: A thermoplastic polymer composition that employs a flame retardant formed from a phosphinic compound and organometallic phosphoric compound is provided. The present inventor has discovered that the organometallic phosphoric compound can counteract the tendency of the phosphinic compound to degrade the mechanical properties of the composition when used at certain concentrations. Furthermore, the present inventor has also surprisingly discovered that the organometallic phosphoric compound may itself act as a flame retardant and thus contribute to the overall flammability performance of the composition. Among other things, this allows compositions to be formed with a lower phosphinic content with the same flammability performance.Type: GrantFiled: July 13, 2009Date of Patent: November 20, 2012Assignee: Ticona LLCInventor: Ram Narayanan

Publication number: 20060251008Abstract: An access-point node to a first network cell of a radio access network, to an access-center node and to a radio access network enable local service providers in rural areas to provide mobile telecommunication at low cost for end users. The access-point node of the invention is configured to establish, maintain, and release a local user-data radio channel, which consists of a first local channel section having as endpoints a first terminal device located in the network cell and the access-point node, and of a second local channel section having as endpoints the access-point node and a second terminal device located in the network cell. The access-point node is configured to exchange packetized user data and control data with an assigned superordinate access-center node for establishing, maintaining and releasing communication between the first terminal device and a third terminal device located outside the network cell. Link cost between the radio access network and the core network may be strongly reduced.Type: ApplicationFiled: June 30, 2005Publication date: November 9, 2006Inventors: Michael Wu, Petteri Alinikula, Rajesh Bansal, Mika Skarp, Ram Narayanan
