  • Patent number: 6562767
    Abstract: A lubricant for wire, which is insulated by means of a lacquer coating, and which is used for forming the stator windings of an electrical refrigerating compressor, consists of one or more compounds of the formula CH3—Xn—R, wherein X is a linear or branched hydrocarbon group with n carbon atoms, wherein n is up to 22, and R may be hydrogen or a plurality of different radicals, either in a pure form or dissolved in a suitable solvent. The lubricant is applied to the wire to reduce its coefficient of friction, and it is remarkable for its compatibility with the environmentally unharmful refrigerants, such as R134a (1,1,1,2-tetrafluoroethane), which are used today in refrigerating compressors without capillary tube obstructions.

  • Patent number: 6548456
    Abstract: Metal working fluids being oil-in-water emulsions comprising alkylated polyvinylpyrrolidones as surfactants for emulsifying the oil in water. The alkylated polyvinyl-pyrrolidones having a molecular weight of about 1,000 up to 50,000 provide emulsions showing a high emulsion stability under varying and severe processing conditions of metal working fluids. Further, advantages of the metal working fluids are the narrow distribution of the droplet size, the high stability against varying temperature, the high stability against varying quality/composition of the make-up water, a high capacity of dispersing metal fines in the metal working fluid as well as excellent film forming characteristics.

  • Patent number: 6358423
    Abstract: The invention relates to a method for treating and conditioning circulated rolling oil, comprising removing dirt and abrasion particles from the returned rolling oil by filtration, feeding filter aids in a controlled manner, and adjusting an electric conductivity preventing electrostatic charging in the purified rolling oil. So that conductivity additives can be omitted, a flocculating agent is employed as the filter aid, and the amounts in which the agent is added depends on the residual contamination remaining in the filtrate, so that a preset minimum conductivity caused by the remaining residual contamination is preserved in the filtrate.

  • Patent number: 6048827
    Abstract: In lubricant (5) of a magnetic recording medium made of conventional perfluoropolyether, one or more conductive high molecular compound is mixed. The conductive lubricant (5) prevents electric charge generated by frictional electricity from staying on the medium surface, and effectively prolongs the head-life by suppressing the break of the head element because of electric discharge between the disk medium and the head element. By employing the conductive lubricant, magnetic recording media and magnetic recording devices which are more reliable and durable can be realized.

  • Patent number: 5626656
    Abstract: A release agent for green sand mold forming contains a hydrocarbon oil as the main lubrication component. The release agent contains a surface active agent as a dispersant and an anion surface active agent and/or a strong basic amine as a wettability improving agent as essential components besides the hydrocarbon oil. The release agent is used in a form of oil-in-water type emulsion by diluting it with water. Since it is possible to dilute the release agent with water, the release agent occupies less capacity during storage and transportation, and since the release agent can increase the water to the hydrocarbon oil ratio of the composition at application, it contributes to improvements in resource saving and safety against fire.
