Abstract:
A composition comprising (a) fine spherical particles of an inorganic substance such as alumina, (b) an aqueous adhesive agent such as a petroleum resin emulsion, and water. It is preferred for better effect that the composition further comprises one or more selected from among (c) a wisker, (d) a powder of an inorganic substance in a form of a scaly crystal, (e) a powder of a metal hydroxide or an inorganic substance having bound water, and (f) a lubricant aid. The composition is free from problems of the occurrence of environmental pollution and the risk of misoperation of an automatic machine, which accompany a conventional graphite lubricating and releasing agent, and that of the danger of smoking or firing, which accompanies a conventional lubricating and releasing agent dispersed in an oil, and is useful as an aqueous lubricating and releasing agent for hot or cold forging using a non-graphite inorganic substance, which is free from occurrence of the deposition on a mold and an under fill phenomenon.
Abstract:
PROBLEM TO BE SOLVED: To provide an improved system for conducting cooling in an extremely low temperature. SOLUTION: A multicomponent refrigerant is compressed in a compressor lubricated with a poly-α-olefin-based oil, the oil is removed from the compressed refrigerant, and the compressed refrigerant is expanded to generate the cooling at the extremely low temperature for the purpose of supply preparation (of the cooling) to a cooling receptor.

Abstract:
A grease composition for a constant velocity joint containing a base oil, a thickener, boron nitride powders, and a sulfur-phosphorus containing extreme pressure agent. The content of the thickener is 2 to 25 weight %, that of the boron nitride powders is 0.5 to 20 weight %, and that of the sulfur phosphorus containing extreme pressure agent is 0.1 to 10 weight %, each based on a total weight of the grease composition. The grease composition exhibits superior anti-flaking performance and can prolong the life time of a constant velocity joint.
Abstract:
PROBLEM TO BE SOLVED: To provide a stable colloidal suspension, which exhibits good frictional properties, oxidation inhibition and anti-wear performance and also lower discoloring, when it is used as a lubricating oil additive for lubricating an oil composition. SOLUTION: The stable colloidal suspension comprises: (a) a dispersed phase comprising a major amount of dispersed hydrated polymeric compounds selected from the group consisting of polymolybdates, polytungstates, polyvanadates, polyniobates, polytantalates, polyuranates, and mixtures thereof, and, (b) an oil phase comprising a dispersing agent and a diluent oil. Processes for preparing the stable colloidal suspensions and their use in lubricating oil compositions are also provided. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
Waterborne lubricants comprising: (A) water-soluble inorganic salt; (B) homogeneously dispersed solid lubricant; (C) at least one homogeneously emulsified substance selected from mineral oils, animal and plant oils and fats, and synthetic oils; (D) surfactant; and (E) water, in which the weight ratio (B)/(A) is from 0.05:1 to 2:1 and the weight ratio {C/(A + B)} is from 0.05:1 to 1:1, provide a one-step, highly lubricating waterborne lubricant for use in the cold plastic working of metals. This waterborne lubricant can replace the conversion coating treatment (phosphate, oxalate, etc.) + reactive soap treatment combined lubrication system now in general use and is free of the environmental issues associated with the combined lubrication system, provides for facile coating removal, and is not subject to the decline in seizure resistance caused by nonuniform add-on when large numbers of workpieces are treated together by immersion.
Abstract:
Described herein is a method for extending lubricant life, comprising treating a lubricant with a lubricant additive which comprises a compound selected from the group consisting of urea, ammonium carbonate, ammonium bicarbonate, and ammonium hydroxide to neutralize acids from oil use and/or contamination by combustion condensates. For example, the lubricant of an internal combustion engine can be treated in situ with an aqueous solution of urea, ammonium carbonate, ammonium bicarbonate, and/or ammonium hydroxide. Also provided is a method for extending lubricant life, comprising use of a urea source on a vehicle that is processed and delivered on board to a lubricant to treat reactive species in the lubricant to increase oil drain interval.
Abstract:
A metal glycol-based hydraulic fluid having vapor phase corrosion inhibition properties is disclosed. The hydraulic fluid can be used in food related applications.
Abstract:
The present invention relates to a method of lubricating a conveyor belt wherein a lubricant concentrate containing at least one fatty acid is employed in a dry lubrication process at a pH- value of 5 is applied to the surface of the conveyor belt on which the lubricant concentrate has been applied earlier.
