Title: Tubing injection system for oilfield operations
Inventor: FONTANA PETER
IPC: E21B19/22
Filed: 1997-09-25
Abstract: This invention provides a tubing injection system (400) that contains one injector (190) for moving a tubing (142) from a source (180) thereof to a second injector (200). The second injector moves the tubing into the wellbore. In an alternative embodiment for subsea operations, the system may contain a first injector placed under water over the wellhead equipment for moving the tubing to and from the wellbore. A second injector at the surface moves the tubing to the first injector and a third injector (195) moves the tubing from the tubing source to the second injector. In each of the tubing injection system sensors are provided to determine the radial force on the tubing exerted by the injectors, tubing speed, injector speed, and the back tension on the source. A control unit (170) containing a computer continually maintains the tubing speed, tension and radial pressure on the tubing within predetermined limits. The control unit is programmed to automatically control the operation of the tubing injection systems according to programs or models provided to the control unit.

Title: Pivotable gutter assembly and kit therefor
Inventor: OBIDNIAK LOUIS
IPC: E04D13/072
Filed: 1998-06-29
Abstract: A gutter system is disclosed which provides a pivoting gutter system assembly. The gutters can be, during summer months, put into the horizontal collecting position to receive rainwater from the roof and to direct it to the down-spout. For the winter months and or maintenance, the gutters are swung-out to downwards vertical position below the roof cornice thus being protected from damage.   A gutter system is disclosed which provides parts for a pivoting gutter system assembly. All parts are standardized and are supplied as a complete system ready to be installed on the fascia of any house roof, and receive standard metal or plastic gutter without them being holed. The kit contains special hangers assuring the correct pitch of the gutters. Also, it contains a down-spout above supplied fixed collector for rainwater, thus permitting the gutters to be pivoted from horizontal to vertical position without the need to disconnect the down-spout.        A wormgear and wormdrive are attached to the end of shaft, outside the house facia; this drive permits to operate the gutter's position from the ground level by an extended bar and manually driven crank or by using electric motor's drive attached to worm and remote control, eliminating the need of a ladder to reach the gutter for changing its position to the downward position particularly important for the gutters installed on the roof high above the ground such as high rise buildings.

Title: Systeme de diversite relatif a des satellites
Inventor: RAMESH RAJARAM
IPC: H04B7/212
Filed: 1996-12-03
Abstract: Ce système de diversité permet à un émetteur-récepteur, tel qu'un dispositif mobile d'un système mobile de télécommunications, d'échanger des signaux de communications avec plus qu'une station de commande telle qu'une station de base ou un satellite. Dans une variante typique de ce système de diversité, le système mobile scanne pour trouver le canal de commande d'un deuxième satellite pendant des créneaux temporels libres, tout en communiquant avec un premier satellite pendant des créneaux temporels actifs. Quand ce système mobile détecte un canal de commande d'un deuxième satellite, il mémorise les informations de synchronisation et établit une liaison de communication avec ce deuxième satellite si un masquage ou un autre affaiblissement grave fait tomber la qualité de signal d'une liaison de communication, établie avec le premier satellite, au-dessous d'un niveau de seuil. Ce système de diversité permet aussi au système mobile de communiquer avec deux satellites simultanément, à l'aide de blocs AMRT alternés.

Title: Calling party invoked held call monitoring
Inventor: MCCONNELL FRED J
IPC: H04M3/493
Filed: 1998-08-07
Abstract: There is described a held party notification monitoring feature which is activated or invoked by a calling party when placed on hold. The monitoring feature is invoked to monitor a communication link established between a first party and a second party wherein the first party has placed the second party on hold. In response to the second party being placed on hold by the first party, a request is generated at the second party to monitor the communication link for a signal indicative of the termination of the hold. Responding to the receipt of the generated request to monitor the communication link for the termination of the hold, a message is generated to the first party indicative that a held call monitoring feature has been activated and awaits the first party to generate the signal indicative of the termination of the hold. In response to the signal being generated by the first party, the second party is alerted of the termination of the hold.

Title: Valve with fire-resistant seal
Inventor: MAKI ROBERT E
IPC: F16K5/06
Filed: 1999-03-15
Abstract: A valve with fire-resistant seal for use in industrial piping applications. The valve includes a valve body with a valve element therein. The valve is illustrated as a ball valve, but other valve configurations could also be used. A valve stem engages the valve element so that it can be rotated between open and closed positions. A conventional primary seal is used on the valve stem for normal conditions. The valve body defines a body bearing surface, and the valve stem defines a facing stem bearing surface. A thrust bearing is disposed between the body and stem bearing surfaces, and a fire-resistant seal is positioned radially inwardly from the thrust bearing. Initially, the fire-resistant seal is not engaged with at least one of the body or stem bearing surfaces, and the fire-resistant seal has a thickness less than an initial thickness of the thrust bearing. If the valve is subjected to heat such that the thrust bearing is destroyed or damaged, pressure loading on the valve stem forces the fire-resistant seal into sealing engagement between the body and valve stem. At least a portion of the fire-resistant seal is forced into a cavity defined in the body by a chamfered surface.
