| 20090156771 | Amine-Containing Compounds for Enhancing the Activity of ATRP Catalysts and Removal of the Terminal Halogen Groups from the ATRP Polymer Products - Disclosed are new, highly active and versatile atom transfer radical polymerization (ATRP) catalysts. These catalysts catalyze ATRP for acrylates, methacrylates, and styrenes at surprisingly low concentrations. These catalysts mediated ATRP at a catalyst/initiator molar ratio at 0.005 and produced polymers with well-controlled molecular weights and low polydispersities. ATRP occurred even at a catalyst/initiator molar ratio as low as 0.001 with metal concentration in the produced polymers as low as 6-8 ppm. Amine-containing compounds, such as triethylamine, can significantly increase the catalyst activity of theses catalysts. The amine compounds can also used to the terminal halogen groups such as Br and Cl in the polymers prepared by ATRP. | 06-18-2009 |

| 20090110394 | 1+1 PROTECTION METHOD OF SERVICES IN OBS NETWORKS, INTERSECTION NODE APPARATUS AND SERVICE PROTECTION SYSTEM - A 1+1 protection method of service in optical burst switching (OBS) networks, an intersection node apparatus, and protection system of service are provided. The method discloses that burst packets bearing service are transferred through two risk-independent routes, and each burst packet corresponds to a control packet. The intersection node receives a first control packet transferred through either route with a sequence number, and then, when it continues to receive the second control packet, which is transferred through the other route with the same sequence number as the first control packet carries within the waiting time of the first control packet, the intersection node selects the burst packet corresponding to the control packet with a smaller quality loss field value of the first and second control packets. The present invention prevents the services from being cut down, and remarkably reduces the packet loss ratio of the service. | 04-30-2009 |
