Title: High temperature superconducting rotor power leads
Inventor: ALEXANDER JAMES PELLEGRINO
IPC: H02K55/04
Filed: 2002-05-02
Abstract: The resistive power leads of a high temperature superconducting (HTS) rotor field coil are located in vacuum near the rotor axis and are cooled by thermal conduction to the return flow path (20) by bonding the leads to the tubing bulkhead (18) through ceramic insulators (22). The lead length, cross-section and electrical resistivity are optimized for minimum heat conduction and ohmic resistance heat transfer to the cold gas. Thermal expansion or contraction of the leads is accommodated by flexible sections at the warm and cold end of the leads.

Title: High-ductility steel sheet excellent in press formability and strain age hardenability, and method for manufacturing the same
Inventor: FURUKIMI OSAMU
IPC: C23C2/02
Filed: 2002-05-24
Abstract: A steel sheet composition contains appropriate amounts of C, Si, Mn, P, S, Al and N and 0.5 to 3.0% Cu. A composite structure of the steel sheet has a ferrite phase or a ferrite phase and a tempered martensite phase as a primary phase, and a secondary phase containing retained austenite in a volume ratio of not less than 1%. In place of the Cu, at least one of Mo, Cr, and W may be contained in a total amount of not more than 2.0%. This composition is useful in production of a high-ductility hot-rolled steel sheet, a high-ductility cold-rolled steel sheet and a high--ductility hot-dip galvanized steel sheet having excellent press formability and excellent stain age hardenability as represented by a ATS of not less than 80 MPa, in which the tensile strength increases remarkably through a heat treatment at a relatively low temperature after press forming.

Patent CA-2388848-A1 (CA)
Inventor: BOYNS MARK RANDLE
IPC: H04L29/08
Filed: 2000-11-02
Abstract: L'invention concerne un système et un procédé de transmission de données vocales sur des protocoles de réseau de niveau élevé, tels que l'Internet et le Web dont les protocoles de niveau élevé sont HTTP/TCP. On évite les restrictions imposées par les coupe-feu et les serveurs mandataires en utilisant des connexions de niveau HTTP pour transmettre des données vocales. En outre, l'utilisation de TCP au lieu de UDP permet de garantir la distribution des paquets. Une compression variable basée sur la détection de silences tire profit des silences et des pauses naturels dans la parole, ce qui réduit les retards de transmission provoqués par l'utilisation de HTTP/TCP. La détection de silences offre la possibilité de prendre les données vocales en sandwich entre des petites parties de silence de sorte que la voix semble naturelle. Enfin, les données vocales sont transmises à chaque ordinateur de client indépendamment d'une liste de données vocales circulaire commune, ce qui garantit que tous les clients reçoivent les données vocales actualisées. La combinaison de ces caractéristiques offre un système de téléconférence simple, cohérent, et interactif sur l'Internet.
Patent CA-2392312-A1 (CA)
Title: A method for removal of solid deposits from electrode surfaces in water disinfecting systems using electrolytic cells, and a device for use thereof
Inventor: HAZIZA HAIM
IPC: C02F1/38
Filed: 2000-11-19
Abstract: The present invention relates to a method and a device for removal of solid deposits from surfaces of electrodes of a DC electrolytic cell for disinfecting of water in a closed system, especially in a swimming pool, SPA  or hot tub, by simultaneous spinning the water over the electrode surfaces and electrolytic release of the deposits from the surfaces without interruption of the disinfecting process, comprising: (a) changing the polarity of the electrodes of the cell at predetermined frequency for electochemically releasing the deposited scale from the electrode surfaces; (b) circulating the water through a hydrocyclone containing a DC electrolytic cell for disinfecting of the water so that said deposits are washed off the electrodes of the cell; (c) periodical removing the scale particles from a drain chamber located at the bottom of the hydrocyclone.

Patent CA-2395023-A1 (CA)
Inventor: TILDEN JOHN N
IPC: A44B11/12
Filed: 2002-07-25
Abstract: An end-fitting buckle having a cam cover that allows webbing to be inserted when the cam cover is in an up position. After inserted, a free end of the webbing is pulled to tighten the webbing while the cover is in an intermediate position. The cover may then be closed to lock both the free end and load end. When the cover is locked, movement of the load end is prevented by teeth in the cam cover. The teeth lock the free end into place, holding the set position of the webbing. The cover design also promotes use of varied thicknesses of webbing, because the cam action of the cover utilizes friction between the two ends of the webbing instead of a pinching action.

Title: Pool liner retainer with cap
Inventor: KINDNESS WILLIAM
IPC: E04H4/14
Filed: 2002-07-25
Abstract: A retainer for a pool liner has an elongate retaining element includes a longitudinal holding channel for accommodating a liner bead, the channel having an upper wall with a downwardly extending second flange, a rear wall and a bottom wall with a forwardly positioned upwardly extending first flange. The area between the second flange and the first flange forms a slot for insertion of the bead into the channel. A third flange is positioned outside of said channel on the upper wall. An elongate resilient cap has a first hooked peripheral edge portion for hooking over the second flange, and an opposed second hooked peripheral edge portion for hooking over the third flange. The cap can be retained by snapping the hooked portions over the respective second and third flanges. The first peripheral edge portion has an outwardly disposed shoulder extending toward the first flange. When the cap is snapped in place, the shoulder is spaced sufficiently from the first flange to allow the width of the liner bead to pass therethrough but not sufficiently to allow the height of the liner bead to pass therethrough.
