Abstract: The present invention relates to the use of polyesters which consist of at least one carbohydrate and at least one carboxylic acid, and mixtures thereof, as a hydraulic fluid.

Abstract: A method and a device for the automatic detection of at least one fluorescent and/or light-absorbent indicator contained in a liquid service fluid during the filling of a machine, in particular a combustion engine of a vehicle, with said service fluid are provided. Detection takes place in the following manner: irradiation during the filling of the service fluid to be analyzed using at least one light source (3) in a measuring section (2); capture of the light (14) passing through the service fluid in the measuring section (2) and/or emanating from the indicator contained in said fluid as a result of a fluorescent effect, by means of a light collector (5), the intensity of the light being influenced by the indicator or indicators or the concentration thereof; generation of at least one measurement signal (8, 9) representing the intensity of the light that strikes.

Abstract: The invention relates to resource operating medium compositions containing additivated lubricants based on polyalkylene glycols and/or neopentyl polyol esters, which are additivated with alkylated triaryl phosphate esters which are suitable for lubricating refrigerators, air-conditioning systems, heat pumps and similar systems which are operated using carbon dioxide as an operating medium.

Abstract: The present invention relates to compositions which comprise mixtures of open-chain and cyclic molecules of the sugar alcohols D-sorbitol and D-mannitol which have been esterified with at least one carboxylic acid, processes for preparing these compositions and the use of this composition as lubricant or hydraulic liquid.

Abstract: The invention relates to novel compositions of matter which may advantageously be used as lubricants or pressure transfer media or else for functional liquids and lubricant additives. The lubricants according to the invention are the reaction products of an electro-philic addition of linear or branched, aliphatic or aromatic carboxylic acids, carboxylic anhydrides, carbonyl halides or novel neoacids to the double bonds of fatty acids, esters thereof and/or of other fatty acid derivatives and also of synthetic esters. Owing to their increased oxidation resistance compared to the starting materials and also their low toxicity, the novel class of synthetic esters based on oleochemicals may find use in novel environmentally compatible lubricants, pressure transfer systems, functional liquids and lubricant additives.

Abstract: The present invention relates to a method for lubricating at least two units of a vehicle having an internal combustion engine, each unit comprising one or more assemblies, and to a corresponding vehicle. In order to be able to dispense with an oil change of the individual units, and at the same time ensure the necessary quality and quantity of lubricant, it is proposed according to the invention to conduct the lubricant in series through the at least two units in that fresh lubricant is fed to the first unit from a container, at least some of the used lubricant is removed from the oil trough of the individual units and is fed to the unit which is respectively arranged afterwards in the series, and the lubricant which is removed from the oil trough of the last unit is fed to the internal combustion engine for combustion.

Abstract: A method and a device for the lubrication and for the simultaneous fuel supply of a vegetable oil-rated internal combustion engine is described in which the internal combustion engine is operated exclusively with vegetable oil thereby that during operation an additive-treated vegetable oil is continuously supplied as lubricant and the used vegetable oil lubricant is combusted in doses as engine fuel together with fresh vegetable oil fuel in the engine.

Abstract: Described is a water-miscible cooling lubricant concentrate which comprises natural or synthetic mineral oils, emulsifying agents, corrosion protection additives, solubilizers, means of preservation, metal inhibitors and other conventional additives, and, after dilution to form a 2 to 25% by weight aqueous solution, has a pH value between 7.0 and 7.5 as well as additionally as means of preservation and/or anticorrosive additive comprises a mixture of a) a conversion product of boric acid and a primary or tertiary alkanolamine and/or b) an ethoxylated and/or propoxylated fatty acid or a fatty acid alkanolamide as well as at least one further compound selected from the group comprised of c) a carboxylic acid imide, a phosphoric acid ester, a triazole, a thiadiazole, an isothiazolinone, an imidazole, a guanidine, an aromatic carboxylic acid and the 3-iodo-2-propinyl-carbamate and/or d) a methylol urea derivative.

Abstract: A method and a device for the lubrication, and for the simultaneous fuel supply, of an internal combustion engine are described. To an internal combustion engine during its continuous operation an additive-treated vegetable oil is supplied as a lubricant. The used vegetable oil lubricant, together with a mixture of fresh vegetable oil and Diesel oil or rape seed oil methyl ester is combusted in doses in the engine as engine fuel.
