Abstract: A coupling for joining two pipes in end-to-end relationship includes flanges which are sealably secured to end sections of pipes to be connected. The flanges form front inclined faces and adjacent front flanges that are slidably received within opposite end openings of a cylindrical coupling. A groove or shoulder is formed at the rear end of the front flanges that cooperate with jaws extending from the ends of the cylindrical coupling to secure the received pipe end portions in the cylindrical coupling to thereby join the pipes together. One or more gaskets fit in the cylindrical coupling between the ends thereof with gasket arms that abut against the inclined surface so that fluid pressure in the pipes force the gasket arms against the inclined faces to provide a seal between the joined pipes. A stop may be provided to limit the sliding travel of the cylindrical coupling with respect to the flanges.

Title: A machinable austempered cast iron article having improved machinability, fatigue performance, and resistance to environmental cracking and a method of making the same
Inventor: FITZGERALD DAVID CARROLL
IPC: C21D9/30
Filed: 2003-08-29
Abstract: A machinable austempered cast iron article has improved strength, machinability, fatigue performance, and resistance to environmental cracking . A method of making the machinable austempered cast iron article includes austenitizing an iron composition having a substantially pearlitic microstructure in an intercritical temperature range of between 1380~F and 1500 ~F. This produces a ferritic plus austenitic microstructure. The ferrit ic plus austenitic microstructure is quenched into an austempering temperature range of between 575 ~F and 750 ~F within 3 minutes to prevent formation of pearlite. The ferritic plus austenitic microstructure is then austempered in the austempering temperature range of between 575 ~F and 750 ~F to produce a microstructure of a continuous matrix of equiaxed ferrite with islands of austenite. Finally, the microstructure of the continuous matrix of equiaxed ferrite with islands of austenite is cooled to ambient temperature to produc e the machinable austempered cast iron article.

Abstract: There are provided a video telephone interpretation system and a video telephone interpretation method capable of coping with an urgent case without requiring search of an interpreter in advance by a caller and negotiation with a call destination, minimizing the on-duty hours of the interpreter, and reducing the interpretation service cost. The video telephone interpretation system (100) receives a call from a caller terminal (10) by a control device (110), references an interpreter registration table (112) to acquire a terminal number of an interpreter capable of interpreting between the language of the caller and the language of the call destination, and connects the caller terminal (10), the call destination terminal (20), and the interpreter terminal (30). Moreover, the system has a function for communicating video and audio required for interpretation between the terminals. The audio of the interpreter is transmitted to the caller or the call destination by an audio switch (174) as is specified by the interpreter terminal and the audio of the conversation partner is suppressed or cut off when the interpreter audio is detected in audio synthesis devices (130, 150), thereby providing a rapid and appropriate interpretation service.

Title: Multi-layer fabric
Inventor: MAJAURY BRIAN G
IPC: D21F1/00
Filed: 2003-12-15
Abstract: A fabric having top and bottom layers, with each layer having machine direction (MD) yarns and cross-direction (CD) yarns interwoven together. The fabric includes pairs of binder yarns that bind together the top and bottom layers. The binder pairs are interwoven so as to be an integral part of the first layer and contribute to a structure thereof. The binder pairs are a no n- integral part of the second layer and do not contribute to d structure thereof. During a repeat pattern, at least one of the two binder yarns of a binder pair is integrally woven with the yarns of the first layer and passes over outer surfaces of, two non-consecutive yarns in the second layer. As a result, a "double knuckle" binding structure may be formed which improves integrity of the resulting composite fabric by reducing the length of the binder yarn path through the fabric.
