Title: Intelligent call redirection
Inventor: GUDELIS MARIUS J
IPC: H04M3/54
Filed: 1997-12-05
Abstract: An intelligent method is disclosed for handling call redirection to an external service provider (ESP) for subsequent call processing. The method uses a network database (30) that contains information regarding calling/called party stations. The database is accessed to determine if an offering of subsequent call processing should be made and how it should be offered. In an exemplary method of handling call redirection, the database is queried to determine whether the calling party station (5) has pre-selected an ESP for subsequent call processing. In the event that the calling party station has pre-selected an ESP, the call is automatically redirected to the pre-selected ESP; no caller input is required. If, however, the calling party station has not pre-selected an ESP, an announcement is played to the calling party offering a menu of available ESPs. To accept the offer, the caller must explicitly respond to the offer using, e.g., DTMF signalling. The call is then redirected on a per-call basis in accordance with the calling party's selection. In addition to storing a calling station's pre-selected ESP, the database can also be used to store other calling and called party station-specific data regarding subsequent call processing, such as a specific condition for redirection (e.g., the number of rings constituting a ring-no-answer trigger condition) or whether the subsequent call processing should be disabled on calls from the calling party station to the called party station (10).

Title: Tube expanding and flange-forming tool
Inventor: DILLER CHARLES E
IPC: B21D39/06
Filed: 1998-09-02
Abstract: A tool for expanding a tube into engagement with a wall of a hole in a plate and simultaneously forming a flange on the end of the tube has a mandrel having a tapered distal portion.  The mandrel receives for rotation and axial displacement a tubular cage.  The cage carries expanding rolls, each of which is supported for rotation in a slot in a distal portion of the cage, is displaceable radially, is in rolling engagement with the tapered portion of the mandrel and the tube when the tool is in operation, and is skewed at a small angle to the mandrel axis so as to impart traction to the cage and the mandrel and draw them distally into the cage upon rotation of the mandrel.  A forming roll is supported for rotation and for displacement radially with respect to the mandrel axis in an opening in the cage and has: at least one conical following surface that is in rolling engagement with the tapered portion of the mandrel; a conical expanding surface that is in rolling engagement with the tube; a forming surface immediately adjacent the expanding surface proximally that is in rolling engagement with the tube; and a conical thrust-receiving surface at a proximal end.  Axial force is transmitted from the cage to the thrust-receiving surface by an annular two race axial thrust bearing, which is supported on and surrounds the cage proximally of the forming roll.

Patent CA-2247685-A1 (CA)
Inventor: RUSSELL THOMAS LEONARD JR
IPC: H04M1/57
Filed: 1998-09-21
Abstract: Various methods are disclosed for enabling a calling party to assist a user of a called party station equipped with a caller ID (CID) display to identify the calling party, rather than simply the phone or phone line from which the calling party is placing the call. An exemplary method includes determining an identity of the calling party without utilizing an identifier of the calling party station, and transmitting the identity of the calling party to the called party station for display on the CID display. Another exemplary method includes determining the identity of the calling party, wherein the identity of the calling party differs from telephone directory information associated with the calling party station, and transmitting the identity of the calling party to the called party station for display on the CID display. The identity of the calling party can be numeric, such as the home telephone number of the calling party, or alphabetic, such as the name of the calling party, and, in either case, is pre-specified by the calling party. In one embodiment, the identity of the calling party is dependent upon the called number. Furthermore, the identity of the calling party can be transmitted to the called party station on a variety of call types (e.g., intra-LATA, O+ calling card, 1 + residential, etc.).

Title: Lining a pipe
Inventor: SHAH ZAHID
IPC: B29C63/34
Filed: 1997-07-10
Abstract: A method of lining an outer pipe (2) which may be of ferrous metal with a lining pipe (4b) of cross-linked polyethylene initially provided as a precursor lining pipe (4a). The precursor lining pipe (4a) is made by forming an initial pipe of cross-linked polyethylene having an external diameter equal to the internal diameter of the outer pipe (2), then the initial pipe is drawn through a die to form the precursor lining pipe (4a) having an external diameter less than the internal diameter of the outer pipe (2). The polyethylene forming the precursor pipe (4a) is memory material having a material of the outer diameter of the initial pipe to which size outer diameter the precursor pipe (4a) expands automatically when the polyethylene is melted. The precursor pipe (4a) is inserted in the outer pipe (2) and the polyethylene is molten by drawing through the precursor lining pipe (4a) a burner (60) burning fuel gas supplied with combustion air through a hose (58) by which the burner is towed. The hot products of combustion melt the polyethylene causing the precursor lining pipe (4a) to expand automatically into the lining pipe (4b) which is supported, until the polyethylene solidifies on cooling, by gas pressure of a desired predetermined value inside the lining pipe (4b). That gas pressure is derived from the pressure of the gaseous products of combustion which latter pressure may be augmented by the pressure of additional air supplied to the interior of the precursor lining pipe (4a).

Title: Integrated thermal process and apparatus for the continuous synthesis of nanoscale powders
Inventor: ANTON BRYCE
IPC: C01F17/235
Filed: 1997-09-03
Abstract: A continuous process that produces nanoscale powders from different types of precursor material by evaporating the material and quenching the vaporized phase preferably in a converging diverging expansion nozzle. The precursor material suspended in a carrier gas is continuously vaporized at very high temperatures, preferably exceeding 2000 degrees C, and most preferably exceeding 5000 degrees K, in a thermal reaction chamber under conditions that favor nucleation of the resulting vapor. Immediately after the initial nucleation stages, the vapor stream is rapidly and uniformly quenched at rates of at least 1,000 K/sec, preferably above 1,000,000 K/sec, to block the continued growth of the nucleated particles and produce a nanosize powder suspension of narrow particle size distribution. The nanopowder is then harvested by filtration from the quenched vapor stream and the carrier medium is purified, compressed and recycled for mixing with new precursor material in the feed stream.
