20080245443COATINGS FOR IMPROVED WEAR PROPERTIES - Lubricated surfaces and methods for improving wear performance of gears and bearings are described. The lubricated surfaces include a manganese phosphate film on the surfaces having a film layer density ranging from about 0.1 to about 0.5 milligrams per square centimeter. A lubricating oil containing a phosphorus anti-wear agent is used to provide lubrication of the surfaces.10-09-2008
20090069205ADDITIVES AND LUBRICANT FORMULATIONS HAVING IMPROVED ANTIWEAR PROPERTIES - Lubricated surfaces, lubricant compositions for lubricating a surface, and methods for increasing antiwear properties in lubricants. The lubricated surface is provided by a lubricant composition including a base oil of lubricating viscosity, at least one metal salt of phosphorothioic acid, and an amount of at least one hydrocarbon soluble titanium compound effective to provide an increase in antiwear properties of the lubricant composition. A ratio of titanium metal to phosphorus in the antiwear agent ranges from about 0.3:1 to about 1.5:1.03-12-2009
20090318318METHOD FOR MAKING A TITANIUM-CONTAINING LUBRICANT ADDITIVE - A method for making a titanium-containing lubricant additive, a lubricant additive concentrate made by the method and a lubricating composition containing the additive concentrate. The method includes reacting titanium alkoxide with water in a reaction medium that includes a dispersant to provide a homogeneous titanium-containing additive product. The additive product made by the method is substantially devoid of acidic components.12-24-2009
20100144563ADDITIVES AND LUBRICANT FORMULATIONS FOR IMPROVED ANTIWEAR PROPERTIES - Lubricated surfaces and lubricant compositions for lubricating a surface. The lubricated surface is provided by a lubricant composition including a base oil of lubricating viscosity, at least one metal salt of phosphorothioic acid, and an ashless, sulfur-free organophosphorus compound providing a metal to phosphorus weight ratio ranging from about 0.25:1 to about 1.0:1 by weight. The lubricant composition is substantially devoid of molybdenum.06-10-2010
20100292113LUBRICANT FORMULATIONS AND METHODS - The embodiments described herein relate to particular formulations and methods that may provide improved fuel economy characteristics for an engine lubricant. The compositions and methods include a (a) a base oil; (b) a zinc dialkyldithiophosphate compound; and (c) a hydrocarbon soluble metal compound. The hydrocarbon soluble metal compound is devoid of phosphorus and sulfur atoms and the metal is selected from the group consisting essentially of selected from the group consisting essentially of cobalt, nickel, zinc, zirconium, manganese, vanadium, scandium, yttrium, tungsten, gold, platinum, and iron. A weight ratio of total metal in the lubricant composition from the zinc dialkyl-dithiophosphate compound and the hydrocarbon soluble metal compound to phosphorus in the lubricant composition ranges from greater than about 1.5 to 1 to about 15 to 1.11-18-2010

20090127457APPARATUS AND METHOD FOR AN ELECTRO-ACOUSTIC ION TRANSMITTOR - A method of transmitting ions along an analyzer region between closely spaced electrodes is disclosed. The method includes providing an analyzer region for transmitting ions, the analyzer region in fluid communication with an ionization source and with an ion detecting device. The method further includes affecting a pressure within at least one portion of the analyzer region, to differ from the pressure within another part of the analyzer region, and providing an electric field that is synchronized with the pressure differences to focus the ions.05-21-2009

20090108195APPARATUS AND METHOD FOR FORMING A GAS COMPOSITION GRADIENT BETWEEN FAIMS ELECTRODES - A method of separating ions includes providing a FAIMS analyzer region for separating ions, the FAIMS analyzer region in fluid communication with an ionization source and with an ion detecting device. The method further includes affecting a gas composition within a first portion of the FAIMS analyzer region to be different from a gas composition within a second portion of the FAIMS analyzer region. The establishment of a gas composition gradient within the FAIMS analyzer region enhances ion focusing and ion transport efficiency.04-30-2009

20100199188Auto-discovery of diverse communications devices for alert broadcasting - Methods and systems for communicating messages to target communications devices in a target physical location are disclosed. Network sources are queried for logical locations accessible to the network source. A specification of a physical location associated with each logical location is received. Each logical location specification is stored in a data store in association with the associated physical location specification. A specification of the target physical location is received. Those logical location specifications associated with the target physical location are retrieved from the data store, thereby identifying target logical locations. For each target logical location, at least one of the network sources accessible to that logical location is queried for specifications of communications devices accessible to that logical location, thereby identifying the communications devices in the target physical location. The message is communicated to the target communications devices in the target physical location via at least one of the target logical locations.08-05-2010
