Patent number: 11078436Abstract: A lubricant formulation which is effective to remove or prevent carbon deposits in internal combustion engines has a solvency as defined by aniline point from about 20 to about 115, a volatility (as measured by NOACK) of less than 15%, an oxidative stability (as measured by PDSC) of above 40 minutes and a base oil viscosity of above 2 and below 10 cSt. The lubricant formulation can be formed from a blend of Group III, IV and V lubricants, in particularly polyalphaolefins, alkylated naphthalenes and polar Group V base stocks such as polyol esters. The carbon deposits can be removed from the engine piston by simply running the engine with the lubricant for one required cycle, or can be used continuously in the engine to prevent buildup.Type: GrantFiled: April 10, 2015Date of Patent: August 3, 2021Assignee: Valvoline Licensing and Intellectual Property LLCInventors: Ying Yang, Frances E. Lockwood, Daniel J. Dotson, Joshua Frederick, Jamie Daasch

Patent number: 8805737Abstract: Systems and methods are provided for operation upon data processing devices are provided for operating with a fraud detection system. As an example, a system and method can be configured for receiving, throughout a current day in real-time or near real-time, financial transaction data representative of financial transactions initiated by different entities. At multiple times throughout the day, a summarization of the financial transaction data (which has been received within a time period within the current day) is generated. The generated summarization is used to determine whether fraud has occurred with respect to a financial transaction contained in the received authorization data or with respect to a subsequently occurring financial transaction.Type: GrantFiled: November 2, 2010Date of Patent: August 12, 2014Assignee: SAS Institute Inc.Inventors: Kevin Chaowen Chen, Vijay S. Desai, William Szczuka, Andrew Engel, Ho Ming Luk, Brian Lee Duke, Daniel J. Dotson, Revathi Subramanian, Paul Charles Dulany

Publication number: 20120317027Abstract: Systems and methods are provided for providing real-time scoring of received transaction data. Transaction data describing a particular transaction that has occurred is received. The transaction data is stored in an enterprise database, where the enterprise database is configured to store transactions of disparate types, where the transaction data is stored using a plurality of segments, where a segment is formatted according to a template, and where the template is selected based on an attribute of the transaction, wherein the attribute is a customer attribute, an activity attribute, or a channel attribute. A transaction type of the particular transaction is determined. One or more models are selected from a pool of models based on the transaction type, wherein the one or more models are configured based on a plurality of records from the enterprise database, and a score of the received transaction data is generated based on the transaction data.Type: ApplicationFiled: June 13, 2011Publication date: December 13, 2012Inventors: Ho Ming Luk, Daniel J. Dotson, Paul C. Dulany, Revathi Subramanian, Brian Lee Duke, Vijay S. Desai

Patent number: 7470650Abstract: The introduction of nanostructures in a liquid provides a means for changing the physical and/or chemical properties of the liquid. Improvements in heat transfer, electrical properties, viscosity, and lubricity can be realized upon dispersion of nanotubes in liquids. Stable dispersions of nanostructures are described and surfactants/dispersants are identified which can disperse nanostructures in petroleum liquid medium. The appropriate dispersant is chosen for the selected nanostructure material and the oil based medium and the dispersant is dissolved into the liquid medium to form a solution. The nanostructure is added to the dispersant containing the solution with agitation, ultrasonication, and/or combinations thereof. Nanostructures dispersed in a fluid form a nanofluid utilized as a shock absorber oil whereby the nanostructures serve to improve the viscosity index of the fluid or more particularly the shock absorber oil in the form of a lubricant additive.Type: GrantFiled: October 15, 2004Date of Patent: December 30, 2008Assignee: Ashland Licensing and Intellectual Property LLCInventors: Zhiqiang Zhang, Gefei Wu, Frances E.

Patent number: 6822012Abstract: This invention relates generally to water resistant peelable protective and decorative clear or pigmented coating compositions and, more specifically, to aqueous and solvent based, polymeric coating compositions which form a protective and/or decorative coating and is removably adheres to a variety of substrates, including automotive paints, metals, glass, vinyl, plastics, concrete, natural and synthetic elastomers, and ceramics. The coatings can be either a flat film on the substrate, or a three-dimensional expandable foamy coating, and can be readily peeled off from the substrate as a whole piece. The coatings may be formulated for temporary or long-term protection depending upon the application. The peelable coatings can be applied as a paint, paste, film, or expandable foam cord whereby the expansion of the foam can be controlled by the formulation and applicator.Type: GrantFiled: October 20, 2000Date of Patent: November 23, 2004Assignee: Ashland IncInventors: Richard J. Baumgart, Michael A. Dituro, Frances E. Lockwood, Zhiqiang Zhang, Daniel J. Dotson
