Abstract: Sensor manifolds include a housing having at least two fluid flow passages communicating with fluid entry and exit ports in the housing that are connectable in line in a full flow fluid line in a system. One or more sensor ports in the housing communicate with one or more of the flow passages for housing one or more sensors for sensing one or more characteristics, qualities or conditions of the fluid flowing through the housing without subjecting the sensor to the full fluid flow through the housing.
Abstract: A linear compound and a metal salt or boron-containing metal salt thereof contains one or more carboxyl-containing phenol units or derivatives thereof and one or more on average at least C18 hydrocarbyl-substituted hydroxyaromatic units or derivatives thereof connected by one or more divalent bridging groups. A concentrate contains the linear compound or metal salt thereof and an organic diluent. A lubricating oil composition contains a minor amount of the linear compound or metal salt thereof and a major amount of a lubricating oil. Additional embodiments of the invention are processes to make the linear compound and the metal salt thereof.

Abstract: A fuel composition contains (a) a medium substantially free of to free of sulphur; (b) a detergent/dispersant additive; and (c) a liquid fuel where the medium substantially free of to free of sulphur is an aliphatic hydrocarbon solvent, and where the aliphatic hydrocarbon solvent is present from at least about 50 wt % to about 100 wt % of the total amount of the medium. The fuel composition is prepared by a process and is useful in a process, where the fuel composition includes a medium that is a hydrocarbon or a nonhydrocarbon or a mixture thereof, to increase the efficiency of an exhaust after-treatment device of an internal combustion engine.

Abstract: Resinous coatings can be applied to glass, exhibiting improved adhesion thereto, by including in the coating composition a sulfonic acid derived compound such as 2-acrylamido-2-methylpropanesulfonic acid or a salt thereof. Alternatively, the glass can be first coated with the sulfonic acid derived compound and thereafter the film-forming resin applied.
