Title: Electronic billing with updateable electronic bill summary
Inventor: GANESAN RAVI
IPC: G06Q30/00
Filed: 2000-08-31
Abstract: An electronic bill payment network includes a plurality of user network stations associated with different users, a plurality of biller network stations associated with different billers, and a central network station. A first user station operates, in real time, to transmit information relevant to an amount of an available bill and an instruction to pay the available bill. A first biller station operates, in real time, to receive the transmitted information and to compute the amount of the available bill based upon the received information. The central network station operates to receive the computed amount of the available bill and the transmitted pay instruction, and to direct payment of the computed amount of the available bill based upon the transmitted instruction to pay that bill.

Patent CA-2319302-A1 (CA)
Title: Stretch film having heat-sealed edges
Inventor: MEHTA DEEPAK H
IPC: B29C53/36
Filed: 2000-09-14
Abstract: A highly stretched film has permanently heat-sealed edges that are nearly invisible. A folding apparatus folds the edge portions of a film to form folded edges. The folded film then is passed through a bridle mechanism having two heated rolls. A series of nips apply pressure to the folded film as it is heated'by the heated rolls. The nip pressure, combined with the heat imparted by the heated rolls, causes thermal welding of the folded edges resulting in permanent heat-sealed edges. Because the film edges are folded prior to the hot-stretching, the hot stretch process performs dual functions of stretching the film and heat sealing the folded edges. The resulting stretched film has permanently heat-sealed edges that do no separate, and which prevent tearing of the film edges during subsequent processing and use.

Title: System and method for optimization of multi-party calls in a satellite network
Inventor: VALENTINE ERIC
IPC: H04B7/185
Filed: 1999-02-25
Abstract: A telecommunications system and method is disclosed for optimizing multi-party calls within a satellite network. This can be accomplished by the Mobile Switching Center (MSC) that the subscriber is currently registered in receiving a multi-party request from the subscriber and determining the most optimal MSC for the given multi-party call. The subscriber can then be re-registered in the most optimal MSC, and either the subscriber or the optimal MSC can set up the entire multi-party call. Alternatively, the subscriber can be re-registered in the optimal MSC, which then sets up the call to the first party of the multi-party call. Thereafter, the subscriber can set up the rest of the multi-party call.

Title: Refractory lining system for high wear area of high temperature reaction vessel
Inventor: HUBBLE DAVID H
IPC: F27D1/04
Filed: 1996-10-21
Abstract: A refractory-lined high temperature reaction vessel comprises a refractory ring lining constructed of refractory brick, a cooler, and a heat transfer medium disposed between the refractory ring lining and the cooler. The refractory brick comprises magnesia (MgO) and graphite. The heat transfer medium contacts the refractory brick and a cooling surface of the cooler, and is composed of a material that accommodates relative movement between the refractory brick and the cooler. The brick is manufactured such that the graphite has an orientation providing a high thermal conductivity in the lengthwise direction through the brick that is higher than the thermal conductivity in directions perpendicular to the lengthwise direction.      The graphite preferably is flake graphite, in the range of about 10 to 20 wt%, and has a size distribution selected to provide maximum brick density. The reaction vessel may be used for performing a reaction process including the steps of forming a layer of slag on a melt in the vessel, the slag having a softening point temperature range, and forming a protective frozen layer of slag on the interior-facing surface of the refractory lining in at least a portion of a zone where the surface contacts the layer of slag, the protective frozen layer being maintained at or about the softening point of the slag.

Title: Apparatus and method for measuring vision defects of a human eye
Inventor: BURKHALTER JAMES H
IPC: A61B3/10
Filed: 1999-04-20
Abstract: Optical characteristics of optical systems, such as the eye (14), are measured including vision defects of the eye using a collimated beam (12) from a diode laser (66) focused onto the anterior surface (22) of the comes (24) of the eye for providing a finite source (16) of secondary radiation on the retina (18) of the eye, the image of which is close to a desired diffraction limited spot. The secondary radiation is reflected back from the retina (18) as a reflected wavefront of radiation that passes through the eye and is directed onto a wavefront analyzer (42) where distortions associated with the reflected wavefront are measured. By focusing on the cornea (24) through a long focal length lens (70) and thus converging the beam through a small angle (13), as opposed to typically focusing a collimated light onto the retina (18), the need for lenses or lens combinations, and the time required to adjust such to accommodate the differing vision of each patient is eliminated.

IPC: C01B17/94
Filed: 1999-08-13
Abstract: According to the present invention, nitrosyl sulphuric acid is mixed with SO2-containing sulphuric acid, and the acid mixture is removed and transferred towards a stripping area. An SO2-containing gas is fed simultaneously into the stripping area, and a gaseous mixture containing SO2 as well as nitrogen oxides is removed from the upper portion of said stripping area. The SO2-containing sulphuric acid is removed from the lower portion of the stripping area and is mixed at least partially with the nitrosyl sulphuric acid. The gaseous mixture removed from the stripping area is fed at a temperature of between 20 and 100~ C into a heating area where said gaseous mixture is heated to a temperature of about 700 to 1300~ C, thus resulting in the decomposition of nitrogen oxides, mainly of N2O.
