Abstract:
Iron-based metallurgical powder compositions are produced by mixing iron-based powder with an improved binder/lubricant that comprises dibasic organic acid and one or more additional components such as solid polyethers, liquid polyethers, and acrylic resin. These novel binder/lubricants impart one or more enhanced green properties to the powder compositions and reduce the ejection force required to remove the compositions from molds and dies.
Abstract:
A synthetic lubricating oil based on an aliphatic polyester derivative having repeating units represented by general formula (I), wherein R and R are as defined in the specification, and a molecular weight of 300 to 2000. This lubricating oil is excellent in the compatibility with a refrigerant and in the lubricity, which renders it suitable as a lubricating oil for a refrigerator, particularly a compression refrigerator.
Abstract:
The title lubricant composition comprises a base oil or base grease and a specified amount of a heat insulating agent comprising (A) an inorganic compound undergoing endothermic melting at temperatures of 1200 DEG C or below and (B) an inorganic powder which neither melts nor decomposes at temperatures of 1200 DEG C or below and which has a thermal conductivity of 0.01 cal/cm.s. DEG C or less and a friction coefficient of 0.7 or less at room temperature added alone or as a combination. This lubricant composition has an excellent heat-insulating effect and is effective in preventing occurrence of thermal crown of working rolls.
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:
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.

PCT No. PCT/CA97/00658 Sec. 371 Date Jun. 22, 1999 Sec. 102(e) Date Jun. 22, 1999 PCT Filed Sep. 11, 1997 PCT Pub. No. WO98/13445 PCT Pub. Date Apr. 2, 1998The present invention relates to novel lubricant compositions comprising a solid lubricant and a binding agent in water medium suitable for lubricating steel-steel interfaces such as tractor-trailer couplings, rail-wheel systems and other heavy duty applications. The invention also relates to compositions described above which include friction modifiers with high or very high and positive coefficients of friction such that the coefficient of friction is considerably higher than the solid lubricant. The invention further relates to compositions comprising a binding agent and a friction modifier with a very high and positive coefficient of friction in a water medium.
