Abstract:
Compositions comprising an oil of lubricating viscosity; an amide represented by the formula R1R2N-C(O)R3 wherein R1 and R2 are hydrocarbyl groups of at least 6 carbon atoms and R3 is a hydroxyalkyl group of 1 to 6 carbon atoms or a group formed by the condensation of said hydroxyalkyl group, through a hy-droxyl group thereof, with an acylating agent; a nitrogen-containing dispersant; and a phosphorus-containing compound are suitable for lubricating a transmis-sion.
Abstract:
A quaternary ammonium salt detergent made from the reaction product of the reaction of: (a) a hydrocarbyl substituted acylating agent and a compound having an oxygen or nitrogen atom capable of condensing with said acylating agent and further having a tertiary amino group; and (b) a quaternizing agent suitable for converting the tertiary amino group to a quaternary nitrogen and the use of such quaternary ammonium salt detergents in a fuel composition to reduce intake valve deposits. ® KIPO & WIPO 2008

Abstract:
The present invention provides a composition containing (a) a substantially nitrogen free dispersant derived from the reaction product of: (i) a polyalkenyl-substituted acylating agent; and (ii) a polyol; (b) a primary metal hydrocarbyl dithiophosphate; (c) an oil of lubricating viscosity; and (d) optionally a viscosity modifier, wherein the composition contains about 35 ppm or less of nitrogen derived from a substantially nitrogen free dispersant. The invention further provides a process for preparing the composition and its use. ® KIPO & WIPO 2007
Abstract:
An apparatus for on-line optical monitoring of the quality and/or chemical condition of a fluid; in particular, a hydrocarbon-based fluid used in transportation and industrial applications. The apparatus includes an IR-transparent internal-reflectance-element (IRE) that has at least one essentially flat surface and at least one convex surface, and at least two IR light paths of uniquely determined central-frequency and bandwidth with light from a source entering a flat surface of the IRE, internally reflecting at least once from at least one convex surface of the IRE that can contact a fluid, exiting a flat surface of the IRE, and being received at a detector. The apparatus also includes electronics to power the source and receive output from the detector of each light path. The apparatus can be controlled to independently monitor the IR light reflected within the IRE at the uniquely determined frequency of each path, and to communicate information relevant to the IR light detected.
Abstract:
A lubricant additive gel formed by the gellation of two or more lubricant additives for the slow release of the additive components into a fluid. The lubricant additive gel slowly releases into its component lubricant additives when contacted with the fluid such as an oil thereby serving as a lubricant fluid such as an oil thereby.
