A composition comprising at least one fuel that is a diesel fuel, a biodiesel fuel, or combinations thereof and less than 100 ppm, less than 50 ppm (or less than 25 ppm, less than 10 ppm, 1 to 7 ppm, or 5 to 7 ppm) of an alkylene-coupled Cto C(or Cto C, Cto Cor Cto C) alkylphenol; 25 to 500 ppm (or 50 to 500 ppm, or 150 to 450 ppm or 250 to 450 ppm, or 250 to 400 ppm) of a terpolymer; and 5 to 90 ppm, (or 10 to 70 ppm, to 60 ppm, or 10 to 55 ppm) of hydrocarbyl-substituted amine detergent having at least one tertiary amino group. Methods of reducing the cold filter plugging point ('CFPP') of a fuel, said method comprising adding the following components: less than 100 ppm, less than 50 ppm (or less than 25 ppm; less than 10 ppm, 1 to 7 ppm, or 5 to 7 ppm) of an alkylene-coupled Cto C(or Cto C, Cto Cor Cto C) alkylphenol; 25 to 500 ppm (or 50 to 500 ppm, or 150 to 450 ppm or 250 to 450 ppm, or 250 to 400 ppm) of a terpolymer; and 5 to 90 ppm, (or 10 to 70 ppm, to 60 ppm, or 10 to 55 ppm) of hydrocarbyl-substituted amine detergent having at least one tertiary amino group. Uses of a fuel additive composition to reduce the cold filter plugging point ('CFPP') of a fuel, wherein the fuel additive composition comprises: 0.2 to 3 wt % of an alkylene-coupled Cto C(or Cto C, Cto Cor Cto C) alkylphenol; 10 to 50 wt % of a terpolymer; and 2 to 10 wt % of hydrocarbyl-substituted amine detergent having at least one tertiary amino group; and an optional solvent.

Wax anti-settling additive composition for use in diesel fuels

The invention relates to quaternary ammonium amide and/or ester salts and their use as additives, including their use in fuels, such as diesel fuel. The invention particularly relates to the use of quaternary ammonium amide and/or ester salts as detergents in diesel fuels.

Quaternary ammonium amide and/or ester salts

A fluid composition of (a) a friction modifier derived from the reaction of a carboxylic acid or a reactive equivalent thereof with an aminoalcohol, the friction modifier containing at least two hydrocarbyl groups; and (b) a dispersant other than a species of (a), provides good friction properties to an automatic transmission.

A set of driver bits for Robertson screw fasteners includes driver bits ( ) whose shaft bodies ( ) have distinctive markings thereon corresponding to respective sizes of working tips ( ) of the driver bits. These distinctive markings are consistent throughout a family of sets. In one embodiment the distinctive marking are different colors, with each different color corresponding to a working-tip size. The colors are applied only to shaft bodies ( ) of some of the driver bits by plating the shaft bodies with zinc layers ( ) and then dying the outer surfaces of the zinc layers with color dye ( ). This coloring is carried out before the shaft bodies are connected to their respective working tips. Once the outer surfaces ( ) of the shaft bodies are thusly colored, the respective working tips are swaged to the shaft bodies to thereby form color-coded Robertson driver bits. In another embodiment, the distinctive markings are surface-irregularity rings ( ) extending about the elongated shafts, with the least number of rings corresponding to the smallest size working tip and the most number rings corresponding to the largest working tip.

Process of making a set of distinguishable robertson driver bits

A method of analysis of and an apparatus for analysing a sample comprising the steps of: (A) examining at least one characteristic of a sample as a function of a variable parameter to obtain data, (B) normalizing the data with respect to a model, (C) making a comparison of the normalized data with reference data, and (D) determining from the comparison the quality of the sample. As a function of such determination of quality, control functions may be carried out with respect to a sample that was analyzed, such as a blend sample in a chemical processing plant.
