This invention relates to N-alkylated anthranilic acid derivative and their use in lubricants, such as engine oils, as TBN boosters. The invention particularly relates to compositions that deliver an ash-free base to a lubricant in the form of a basic amine additive, without adversely impacting seal compatibility and/or degradation, and methods thereof.

The present invention relates to lubricating compositions and particularly gear oil compositions that include a specific class of substituted triazoles, where the substituted triazole includes at least one hydrocarbyl group linked to one of the nitrogen atoms in the triazole ring. Such compositions provide surprisingly good seal compatibility compared to compositions with other triazoles and/or alternative additives.

A grease composition is disclosed which is intended primarily for use in constant velocity joints (CV joints), especially ball joints and/or tripod joints, which are used in the driveline of motor vehicles. The grease composition for use in constant velocity joints comprises at least one base oil, at least one thickener, zinc sulfide, at least one copper sulfide and molybdenum disulfide and/or tungsten disulfide. Further, the present disclosure relates to a constant velocity joint comprising such a grease composition.

A constant velocity joint having a boot constructed from a thermoplastic polyether ester as the boot material. The boot includes a lubricating grease composition for lubricating the constant velocity joint, the lubricating grease composition comprising calcium lignin sulfonate.

A lubricant composition comprising a base oil; at least one additive; and 0.001-10% by weight, based on the total weight of the lubricant composition, of an organic compound comprising both a polar moiety and a nonpolar moiety, as lubricity improver, wherein the organic compound has a relative permittivity ε.sub.r in the range from 1.5 to 10, and a quotient ∫S.sub.1/∫S.sub.2 for the organic compound is in the range from 1 to 25, wherein ∫S.sub.1 denotes the sum total of the area(s) of the IR absorption band(s) in the wavenumber range of 3100-2750 cm.sup.−1 in an ATR spectrum of the organic compound, and ∫S.sub.2 denotes the sum total of the area(s) of the IR absorption band(s) in the wavenumber range of 1800-1650 cm.sup.−1 in an ATR spectrum of the organic compound.

A system and method are provided for detecting a botnet in a network based on traffic flow, daisy chained mechanism and white-list generation mechanism. The system and method uses the known malicious components in a botnet such as IP address, domain name and URL, to be the root of a daisy chain and creates a network graph based on given traffic flow data such as NetFlow data, DNS cache data, DNS sinkhole data, DDoS data and Attack log data in threat sensors. The system and method iteratively detects new malicious factors by tracing that network graph. The system and method also introduces a technique to create a white list which is used in the daisy chain to reduce false positive.

The present invention provides a refrigerating machine oil composition comprising an ester-based base oil, an epoxy compound, and a carbodiimide compound, the refrigerating machine oil composition being used with a refrigerant containing a fluoropropene in a refrigerating machine comprising a member containing polyethylene terephthalate and/or a member containing hydrogenated acrylonitrile butadiene rubber.
