    摘要： Disclosed is a process for the preparation of multilayered, shaped articles having high transparency and low haze having at least one layer contains one or more thermoplastic polymers selected from polyesters, polycarbonates, and homogeneous blends thereof, and a separate layer which contains a transamidized, homogeneous blend of a least two polyamides. The thermoplastic polymer components and the polyamide components have refractive indices which differ by about 0.006 to about −0.0006. The small difference in the refractive indices enable the incorporation of regrind into one or more of the layers of the article while maintaining high clarity. These articles can exhibit improved excellent barrier properties and good melt processability while retaining excellent mechanical properties. Metal catalysts can be incorporated into one or more layers to impart oxygen-scavenging properties.

    摘要： A subscriber of a telecommunication system has a plurality of associated telecommunication devices which are each contactable via a device-shared identification address. A first device can communicate with a telecommunications network. A second device can communicate with a packet-switched network and a circuit-switched network. A control system receives an incoming telecommunication request associated with an incoming telecommunication request directed to the address, which has been routed to the control system based on the address. A first control phase is initiated where a first outgoing telecommunication request is transmitted over the telecommunications network to the first device and an operation is performed to at least attempt to transmit a second outgoing telecommunication request over the packet-switched network to the second device. If the operation is deemed to be unsuccessful, a second control phase is initiated where a third outgoing telecommunication request is transmitted over the circuit-switched network to the second device.
