Patent CA-2329954-A1 (CA)
Inventor: KEMENY FRANK L
IPC: G01S13/88
Filed: 1999-08-12
Abstract: Radar is used to measure not only the level of slag (3) on molten steel (2) but also its thickness. The measurement is used to calculate the volume of slag (3), and, in tum the amount of additives for slag treatment. Time-of-flight data are used to identify peaks representing the distances of the surfaces of the slag (3) and the surface of the underlying steel (2). The concept is applicable to other materials of differing composition, and particularly where the underlying material is relatively more conductive than the overlying material.

Patent CA-2334895-A1 (CA)
Inventor: MUSTER THOMAS
IPC: C12N7/00
Filed: 1999-06-11
Abstract: The present invention relates, in general, to attenuated negative-strand RNA  viruses having an impaired ability to antagonize the cellular interferon (IFN) response, and the use of such attenuated viruses in vaccine and pharmaceutical formulations. The invention also relates to the development and use of IFN-deficient systems for selection of such attenuated viruses. In particular, the invention relates to attenuated influenza viruses having modifications to the NS1 gene that diminish or eliminate the ability of the NS1 gene product to antagonize the cellular IFN response. The mutant viruses replicate in vivo but demonstrate reduced pathogenicity, and therefore are well suited for live virus vaccines, and pharmaceutical formulations.

Title: Circuit breaker with instantaneous trip provided by main conductor routed through magnetic circuit of electronic trip motor
Inventor: JUDS MARK ALLAN
IPC: H01H83/20
Filed: 2001-02-14
Abstract: The toggle mechanism of a circuit breaker is connected at one end to the pivoted contact arm and at the other end to a pivoted latch lever which is engaged to latch the toggle mechanism by a latch member pivoted for movement in a plane perpendicular to the plane of the toggle mechanism. The latch member serves as an armature for a trip motor energized by a trip circuit responsive to an arc fault and/or a ground fault to unlatch the toggle mechanism and trip the circuit breaker open. The latch member is also tripped by a helical bimetal responsive to persistent overcurrents and coupled to the latch member through an ambient compensator bimetal cantilevered from the latch member. A flexible shunt connected between the helical bimetal and contact arm passes through an extension of the magnetic circuit of the trip motor to generate a magnetic field of sufficient strength to trip the latch member instantaneously in response to a short circuit.
Patent CA-2337311-A1 (CA)
Title: Methods and apparatus for reducing heat load in combustor panels
Inventor: LASTRINA FRANK A
IPC: F23R3/00
Filed: 2001-02-15
Abstract: A combustor liner (40) has a stepped combustor liner surface (70) defining a combustion zone (36) and an overhang portion (74) forming an air cooling slot (78). A layer (90) of thermal barrier material is applied to the combustor liner such that at least one portion (96) of the combustor liner receives a layer of thermal barrier material with a thickness (T,) greater than 0.01 inches. Thus, the combustor liner absorbs less heat, and the combustor (30) may operate at higher temperatures. As a result, low cycle fatigue and thermal creep are reduced within the combustor and the life cycle for the combustor is extended.

Title: In-press process for coating composite substrates
Inventor: IDOL TRAVIS W
IPC: B05D3/02
Filed: 1999-11-04
Abstract: An improved process for manufacture of polymer coated composite substrates is described. A coated composite substrate is prepared in the press by applying a layer of a primer coating composition to the surface of a compressible mat comprising fibers and/or particles and a resin binder. The primer coating composition is formulated preferably as a fast setting polymer latex capable of forming a chemically crosslinked polymer matrix when applied to the surface of a compressible mat.  A thermosetting top coat composition can be applied directly over the wet primer coating composition before heat-processing the mat to improve surface quality and release characteristics. Compressing and heating the coated mat produces a primed composite substrate directly out of the press.

Title: Multi-chamber airbed
Inventor: BARNETT J PATRICK
IPC: A47C27/10
Filed: 2001-07-27
Abstract: A multi-chamber airbed reduces the effect of weight movement by one or more persons sleeping or sitting on the airbed. In the multi-chambered airbed of the present invention, there are at least two chambers inside the airbed, each chamber having its own air valve and representing its own portion of the airbed. The chambers are completely sealed off from each other by a barrier or septum within the airbed. Thus, when one person shifts his or her weight on the portion of the airbed over one chamber, air does not flow to the other chamber or portion of the airbed.

Title: Plastic window assembly
Inventor: ALLEN CLYDE G
IPC: G07F17/34
Filed: 2001-07-30
Abstract: A plastic window assembly is adapted to be mounted in an opening defined by a structure.  The plastic window assembly is oval-shaped with a decorative plastic window muntin.  A plastic frame supports parallel window panes.  The window muntin is disposed between the parallel window panes.  Flat surfaces of the window muntin have a first edge and a second edge and include a ridge disposed along each of the edges. Marring of the window panes is prevented because the ridge provides for line contact between the window muntin and the window panes.  The window muntin may also be integrally molded to a plastic pane disposed between the parallel panes of glass.  The plastic pane includes a surface texture that simulates frosted glass.  The plastic window assembly includes a plurality of liner panels that extend through the opening from an interior of the structure.  The window assembly includes a flange having aperture throughwhich fasteners are inserted to secure the window assembly to the structure.  An exterior trim ring attaches to the outside of the window assembly and over siding on the structure.  An interior trim ring attaches to a flange in the liner panel to give a finished appearance.  All exposed surfaces include a surface texture that simulates wood grain.

Title: Bandwidth allocation in ethernet networks
Inventor: CUNNINGHAM IAN M
IPC: H04L12/56
Filed: 2001-11-29
Abstract: For assigning bandwidth in a constrained topology ethernet network there is presented a function that creates and manages a ledger of bandwidth requests  over the ethernet network. The function, a bandwidth manager, tracks the total bandwidth of each link in the network and the bandwidth that has been reserved on each link.  When traffic is granted reserved bandwidth the bandwidth manager notes th is allocation in the ledger. The header of the traffic packets indicates that t he traffic is of highest priority when the traffic has been given reserved bandwidth. In this manner the bandwidth manager can track and limit the amount of high priority  traffic on the network.
