Abstract: The invention relates to a method for the preparation of estolide esters from a hydroxycarboxylic acid by a reaction of addition of a fatty acid to the hydroxyl function and by a reaction of esterification of the carboxylic acid function with an alcohol. The invention further relates to the use of estolide esters as a base oil in a lubricating composition or as an emollient in a cosmetic or pharmaceutical composition.
Abstract: The invention relates to the use of an oil that does not include tricresyl phosphate and includes as an anti-wear additive at least one diphosphorus compound for the prophylaxis of aerotoxic syndrome, especially in case of fume event. It also relates to the oil as such.
Abstract: The use of an additive including a mixture of oligomers that is produced from the reaction of aromatic amines chosen from: (i) the reaction with one another of diphenylamine (DPA) compounds of formula (I) below: wherein the groups R1 and R2 stand for, independently of one another, a hydrogen or a linear or branched alkyl group having from 1 to 30 carbon atoms, advantageously from 4 to 12 carbon atoms, (ii) the reaction with one another of phenyl-?-naphthylamine (PAN) compounds of formula (II) below: wherein the group R3 stands for a hydrogen or a linear or branched alkyl group having from 1 to 30 carbon atoms, advantageously from 4 to 12 carbon atoms, and (iii) the reaction of a (DPA) compound of formula (I) above with a (PAN) compound of formula (II) above as an agent for the stabilization of a lubricating composition for a conveyor chain subjected to a temperature of at least 120° C.

Abstract: New anti-oxidation and/or anti-corrosion agents representing new products resulting from the reaction of a diphenyl amine compound (DPA) with a phenyl-?-naphthyl amine compound (PAN), possess improved properties, as compared to known additives. Lubricating compositions, in particular for turbines, containing the novel anti-oxidation and/or anti-corrosion agents, and a method for preparing the novel anti-oxidation and/or anti-corrosion agents, as well as the novel lubricating compositions are described.

Abstract: Paper is unwound from the inside diameter of a tubular roll of paper in a dispensing container, is threaded downwardly through a dispensing funnel installed in a hole in the bottom wall of the container, and is adapted to be pulled downwardly from the funnel and torn into individual hand wipers. The funnel is formed with three dispensing ports of different sizes to accommodate paper of different thicknesses and includes an angled lower end portion which promotes reliable tearing of the paper and causes a tail of predetermined length to be left extending from the funnel for use in the next dispensing operation. The angled lower end portion of the funnel may be pointed forwardly if the dispenser is mounted at a relatively high elevation and may be pointed rearwardly if the dispenser is mounted at a relatively low location. The funnel may be installed securely in holes of different diameters and used with bottom walls of different thicknesses.
