IPC: C09K21/04
Filed: 2003-05-30
Granted: 2010-05-11
Abstract: A fire proof treatment solution capable of resolving problems, such as low solubility leading to low concentration and hence low combustion inhibiting effect and water solubility leading to a disadvantage of eluviation, of boron compounds used as a constituent of flame retarding treatment solution. In particular, a fire proof treatment solution produced by adding phosphoric acid and a silane coupling agent to a weak acid or weak alkali aqueous metal salt solution containing a boron compound to thereby obtain a mixed aqueous solution and adding a plant extract composed mainly of a polyphenol compound to the mixed aqueous solution. This fire proof treatment solution can be widely applied to members composed mainly of cellulose, such as wood, paper and natural fibers.  This fire proof treatment solution can increase the fixation of chemicals to thereby attain a high combustion inhibiting effect and can minimize the occurrence of eluviation.

Abstract: The present invention provides overbased detergents as lubricating oil additives effective for the lubrication of mechanical components in land and marine engines, such as, for example, hydraulic systems, transmissions, two-stroke and four-stroke vehicular engines, trunk piston and two-stroke crosshead marine engines. These overbased detergents lead to improved detergency and thermal stability performances versus high overbased sulfonates. Moreover, they are more compatible with commercial phenates than conventional sulfonates. The overbased detergent is obtained by the process of (I) preparing a surfactant system comprising an alkyl aromatic sulfonate and an alkylphenol or an alkylhydroxybenzoic acid derivative and (II) reacting the surfactant system with a source of alkaline-earth metal and an acidic co-agent.

Title: Extraction process for reactive metal oxides
Inventor: JHA ANIMESH
IPC: C01F7/142
Filed: 2004-06-11
Granted: 2012-08-28
Abstract: The present invention relates to a zero-waste process for extraction of alumina from différent types of bauxite ores and red mud residues and of titanium dioxide from ilmenite. Iron oxide is first reduced to metallic iron above the melting point of C-saturated cast iron alloy which yields a high-C iron alloy and an AI and Ti metal oxide rich slag which is then treated with alkali carbonate to form alkali aluminates and titanates. The alkali aluminates are separated by water leaching from which the hydroxide of alumina is precipitated by bubbling C02. The residue from water leaching is treated with sulphuric acid and Ti02 is precipitated via a hydrolysis route. The process recovers most of the metal values and generates only small quantities of silicious residues at pH 4-5 which can be used for soil conditioning. The present also relates to a method for selective separation of Ti02-rich oxides from titaniferrous ore/residue materials via oxidative roasting in the presence of alkali carbonate or carbonates followed by aqueous leaching of the roasted material and selective precipitation of Ti02 under controlled condition below pH=4.

Patent CA-2531414-C (CA)
Inventor: WILKOWSKE ERIC JOHN
IPC: A61M25/092
Filed: 2005-12-22
Granted: 2010-12-14
Abstract: The present invention is a method of manufacturing a flexible tubular body for catheter, sheath or similar medical device. The method comprises pre-extruding an inner layer of the body from a thermoplastic polymer and then pulling the inner layer over a mandrel and tightening the layer down. If wire lumens were not integrally formed in the inner layer when pre-extruded, then two polymer spaghetti tubes, each with wire lumens, are laid 180 degrees apart axially along the outer surface of the inner layer. Deflection wires are then fed into the wire lumens. A cylindrical wire braid is woven or pulled over the inner layer (and the spaghetti tubes, as the case may be) and tightened down. The aforementioned components are then encased in an outer polymer layer. A heat-shrinkable tube is then placed over the outer layer. A pressurized fluid is injected into each wire lumen to maintain the internal diameter of each wire lumen at a diameter that is greater than the diameter of the deflection wire received in each wire lumen. Heat is then applied to the body and heat-shrinkable tube to cause the layers to laminate together. Once the newly laminated body has sufficiently cooled, the heat- shrinkable tube is removed from the body.

Title: Two-wire bus instrument
Inventor: MANSFIELD WILLIAM M
IPC: H02H9/00
Filed: 2003-09-30
Granted: 2012-11-20
Abstract: An intrinsically safe two-wire bus instrument such as a flowmeter for hazardous environments and adapted for use with a two-wire bus. An instrument element receives a third current and generates one or more sensor measurement signals. A signal processor receives a second current and processes the one or more sensor measurement signals to produce a data signal.  A communication system receives a first current, receives the data signal, generates a digital communication signal including the data signal, and modulates the digital communication signal onto the two-wire bus. The first, second and third currents are respectively provided by a communication power supply, a signal processing power supply and a drive current power supply, each of which is connected across the two-wire bus. The instrument can be constructed to be entirely intrinsically safe and thus avoid the need for a bulky and expensive explosion-proof housing.

Title: Touch fastener with magnetic attractant
Inventor: ROUTHIER BRIAN J
IPC: A44B18/00
Filed: 1996-02-16
Granted: 2007-01-02
Abstract: A fastening component of a separable fastener has some portion that is necessary for its fastening function, such as the hooks, the base to which the hooks are attached or a substrate that is used for another purpose, comprised of a magnetically attractive constituent. Another portion of the fastening component is comprised of a magnetically inert constituent. The fastening element may be the hook portion or the loop portion of a typical fastener. The fastening elements and the base may be unitary, or of different precursors, such as in a woven fastener component. The magnetically inert constituent may comprise a polymeric plastic or a thermoplastic elastomer. The magnetic attractant may impregnate the magnetically inert constituent, or it may coat or be coated by the magnetically inert constituent. The magnetic attractant may comprise a metal powder. The metal may be selected from the group consisting of iron powder. The magnetic attractant may be an organo-iron or a rare earth metal. In a woven fastener, either the base structure or the hooks may include the magnetic attractant, or both may do so.      The material that forms the hooks may be entirely of a magnetically attractive material, with the material that forms the woven base being magnetically inert. Rather than the magnetically attractive material being incorporated into the fastening elements or the base, it may be incorporated into the substrate that is formed from a precursor element that is separate from the base, and that is joined to the base.
