Abstract: A gas turbine engine has an engine core including a primary flowpath. A first bypass duct is positioned radially outward of the engine core. A gas discharge protrudes radially into the first bypass duct. The gas discharge includes a fairing defining a lobed outlet. The lobed outlet includes a plurality of axially aligned peaks and axially aligned valleys. Each of the axially aligned valleys is configured to prevent a fluid passing through the valley from traveling radially inward immediately downstream of the fairing creating regions of relatively cool, mixed, and hot airflows.

Abstract: A method using an Internet or similar connection to provide network users with information about and control over a communications service feature. A communications switch routes communications in the network to and from the user and a feature control process provides the communications service feature to the user. A processor in communication with the feature control process and a user terminal provides the user with information about and control over the communications service feature at the user terminal. The process can be a dedicated Internet server and the user can manage the communications service feature from a home page displayed on the user terminal.

Abstract: A method and apparatus using information stored in a communications switch to trace a specific communication in a network, including an in-progress communication. A search request with a set of search criteria is sent to a communications switch that routes communications in the network. Information stored in the communications switch, such as a communications switch call record, is searched to locate information matching the set of search criteria in the search request. The results of the search are reported out of the communications switch allowing the specific communication to be traced.

Abstract: A prior art crossbar switching system provides a test frame connector which may be seized by a marker for the purpose of causing a trouble data record to be made (e.g., by a trouble recorder card perforator). All markers compete for normal seizure of the connector by means of the usual connector seizure circuit arrangement of preference relays and connector relays whereby normal marker seizure attempts are recognized and served so that only one normal seizure at a time is permitted. A new interface circuit is provided so that a computer can effect a special seizure of an idleconnector and so that no normal seizure attempt can be recognized by the seizure circuit while the special seizure situation prevails; however, the interface can detect a normal seizure attempt which occurs at any time while the special seizure is in the process of being effected.
