    摘要： A continuous or batch process for the production and recovery of substantially pure carboxylic acids and ammonium salts from a corresponding nitrile. By controlling the amount of water used in the reaction, a biphasic reaction mixture forms which facilitate simultaneous recovery of both fractions. In a preferred embodiment, using propionitrile as the starting material and strong sulfuiric acid, propionic acid of approximately 98% purity is produced in the upper phase. A combination of hydrochloric and sulfuric acid can reduce the total reaction volume.

    摘要： A system and method for routing calls from a communication system in a VoIP network to an external network. The communication system comprises a plurality of communicating nodes. The communication system is configured to request routing information from a register associated with the external network for routing a communication to a subscriber of the external network, receive routing information from the register, and establish an external connection from the VoIP network for routing the communication to the external network based on the routing information.

    摘要： A hinge mechanism includes a first hinge element, a second hinge element, and a locking element. The first and second hinge elements each include a plate portion and a plurality of substantially parallel fingers spaced from one another. The pluralities of substantially parallel fingers interlock with one another along a pivot axis such that the first and second hinge elements are rotatable relative to one another about the pivot axis between an extended position and a folded position. The locking element extends substantially parallel to the pivot axis and may be configured to releasably engage a receiving portion in one of the pluralities of substantially parallel fingers when the first and second hinge elements are in the extended position to lock the first and second hinge elements relative to one another. A collapsible ascension ski having such a hinge mechanism as well as related methods and kits are also disclosed.

    摘要： A communication system includes a switching network and a wireless network. The switching network includes a first gateway for receiving a communication from a caller, a second gateway for establishing an external connection through which the communication can be routed, and a command center that allows the first and second gateways to make an internal connection. The wireless network includes a visited mobile switch center and a home location register. The visited mobile switch center generates routing information, receives the communication from the external connection of the switching network, and routes the communication to a wireless network subscriber. The home location register locates the visited mobile switch center, and passes the routing information from the visited mobile switch center to the command center of the switching network. The command center causes the external connection to be established based on the routing information.
