Inventor: LEONARD MARK R
IPC: D21H23/26
Filed: 1997-08-28
Abstract: Making paper for corrugating medium includes forming a sheet of pulp material, partially drying the sheet of pulp material to provide a partially dried sheet, applying a crack-reducing agent to surfaces of the partially dried sheet, and providing a sheet of paper by drying the partially dried sheet after applying the crack-reducing agent. Forming a sheet of pulp material may include providing a pulp slurry to aheadbox having a slice and carrying the pulp slurry that exits from the slice away from the headbox using, for example, a Fourdrinier. The Fourdrinier may also drythe sheet.

Patent CA-2214602-A1 (CA)
Title: Flap wheel
Inventor: EMERSON GRAHAME W
IPC: B24D13/16
Filed: 1997-08-29
Abstract: In one embodiment, a support member on an abrasive wheel has (a) an annular surface which fixedly supports (as by epoxy) a plurality of flaps in a partially overlapping relationship between successive flaps and (b) a central hole for receiving a mandrel which rotates the wheel.  Each flap has on one of its surfaces abrasive particles facing outwardly from the annular surface.          Each flap defines an acute angle with the annular surface and preferably extends at its opposite axial ends beyond the axial positions of support by such support surface to obtain a fixed positioning of the flaps relative to the support surface even at the axial positions beyond the axial ends of such annular surface.  In a second embodiment, the flaps are disposed on the annular support surface in a tighter relationship than in the first embodiment so that each flap contacts adjacent flaps along a portion of its length.  When the wheel is rotated with the flaps disposed adjacent a workpiece, the inner portions of the flaps provide an abrading action, partly because of their contact with one another, and the outer portions of the flaps provide a polishing action, partly because of their separation from one another.  This polishing action is facilitated by the fact that (a) the flaps become separated from one another at their outer ends because of centrifugal action and (b) the grit on the flaps becomes progressively worn with progressive positions toward the outer ends of the flaps.

Title: Televoting in an intelligent network
Inventor: PYK LIST MIKA
IPC: H04Q3/00
Filed: 1996-04-12
Abstract: The invention relates to a method and arrangement for televoting in an intelligent network. In the method, (a) a point (SCP) comprising a service control function SCF sends a televoting activation request to a point (SSP) comprising a service switching function SSF; (b) the point comprising the service switching function SSF counts the calls made by the users of the telephone network to predetermined telephone numbers; and (c) information on the number of calls is forwarded to the service control function SCF of the intelligent network. In order that faultless televoting in a multi-SCP environment could be guaranteed, the point comprising the service switching function SSF makes comparisons, upon receiving a televoting activation request, to find out whether a televoting process activated by some other service control point and using the same or some of the same telephone numbers is in progress, and if so, the point comprising the service switching function SSF does not start a televoting process.
Patent CA-2217576-A1 (CA)
Title: Method for modifying surfaces with ultra thin films
Inventor: ARORA PRAMOD K
IPC: B05D1/18
Filed: 1997-10-07
Abstract: A faster and more efficient method for applying ultra thin films to substrate surfaces is disclosed.  The method comprises heating a film forming composition comprising amphiphilic molecules to a liquid state, immersing the substrate surface in the heated liquid composition to heat the surface, and washing away the excess composition. For surfaces that ordinarily have insufficient or no chemical moieties reactive with the amphiphilic molecules, the immersion in the heated composition causes the substrate to become porous and expose previously unavailable chemically reactive moieties in the surface matrix.  The amphiphilic molecules then self-assemble, chemically bond to the surface matrix and self-polymerize with each other and with other surface matrix-bound and/or surface-bound molecules to form the ultra thin surface film.  The method is also faster and more efficient for coating non porous and metal surfaces.

Title: Apparatus and method for milling a well casing
Inventor: BRUCE RONALD JAMES
IPC: E21B4/20
Filed: 1996-10-07
Abstract: Apparatus for milling the casing of an oil or gas well comprises a downhole assembly which is run into the well on a rotatable drill string. The assembly comprises a motor (6) the body of which is connected to the drill string and the output shaft of which is connected to a casing mill (9). In use, the drill string is rotated in one rotational direction and the motor (6) is operated to rotate the output shaft thereof in the same rotational direction whereby the speed of rotation of the mill (9) is faster than the rotational speed of the drill string. Because the rotational speed of the milling tool (9) cannot be less than the rotational speed of the output shaft of the motor (6) relative to the body thereof extreme variations in the rotational speed of the milling tool due to winding up of the drill string are avoided. The downhole assembly may incorporate a taper mill (11), stabilizers (10, 8 and 5) and a jet sub (4). The assembly may also incorporate a constant thrust device for producing a substantially constant thrust loading on the milling tool and one or more cement removing tools.

Abstract: A system for determining the disposition of a probe within the body of a patient includes a probe (20) having probe field transducers (30) and a plurality of reference field transducers (100A)-(100C). The reference field transducers are independently moveable with respect to one another to desired, customized positions close to the body of the patient.

From the detected fields, the relative disposition of the probe with respect to the reference field transducers is determined.
Patent CA-2247066-A1 (CA)
Inventor: YEN WEI
IPC: G06F17/30
Filed: 1997-12-17
Abstract: The invention provides a method and system for receiving incoming information from multiple information sources, both interactive and passive, and for engagingly presenting that information to a recipient on a presentation interface. The system includes a "background" element, which interacts with interactive information sources and receives from passive information sources, and determines whether information from those sources is likely to be interesting to the recipient, possibly using one information source to determine priority for another. The system also includes a "foreground" element, which presents information to the recipient when active, but not when inactive. The background is operative even when the foreground element is inactive, and when the background detects new information of interest to the recipient (for example, exceeding a selected threshold of interest or satisfying a selected criterion for interest), it causes the foreground to become active and engage the recipient to select and view that new information. The threshold or criterion may be adaptively responsive to recipient preferences,  whether explicitly expressed or implied, but may also be relatively fixed, such as a scheduled time of day.

IPC: H04Q3/545
Filed: 1998-10-29
Abstract: Method and apparatus for alleviating switch congestion caused by long hold times for on-line access calls. An originating switch is connected to a dedicated data network which is in turn connected to a point-of-presence for an on-line service provider such as an Internet service provider (ISP). On-line access calls, once identified, are routed through this dedicated data network and not the public network, thereby alleviating switch congestion in the public network. The dedicated data network is connected directly to a data port on the originating switch and the originating switch provides all protocol conversion needed.
