  • Patent number: 7932219
    Abstract: The present invention provides a grease composition which prevents frictional wear of a lubricating surface in a high load-applied state or in a state in which sliding motion is generated and is durable for a long time, a method of manufacturing capable of easily determining an addition ratio of an extreme-pressure agent of the grease composition, and a rolling bearing in which the grease composition is enclosed. A grease composition is composed by adding a thickener and an extreme-pressure agent containing sulfur in a molecular structure thereof to base oil. The extreme-pressure agent is added to the base oil so that a product of an amount (mgS/g) of active sulfur contained in the extreme-pressure agent and an addition amount (wt %) of the extreme-pressure agent with respect to an entire amount of the grease composition is in a range of 3 to 13.

  • Patent number: 7919439
    Abstract: With a powdered lubricant composition by the invention, in addition to the blending of one of anhydrous, pentahydrate or decahydrate salt in sodium borate and one of sodium or calcium salt of fat acid, mixing calcium or lithium carbonate as an auxiliary lubricant can prevent sodium borate (Na2B4O7), solidified as amorphous after a tube-making process, from moisture absorbance, drying and crystallization to thereby suppress the formation of Na2B4O7.5H2O on inside surfaces of finished-product tubes, thus enabling to circumvent occurrence of the white scales. Concurrently, they provide good diffusivity toward the working surface of workpiece, thus enabling to prolong a life of the mandrel bar and to widely be adopted as the most suitable powdered lubricant for manufacturing seamless tubes by Mandrel Mill rolling.

  • Patent number: 7914666
    Abstract: An FCC process producing lower NOx emissions during regeneration by using excess oxygen levels at less than or equal to about 0.5 mol-% and a plenum temperature above about 730° C. (about 1350° F.). The process may further include limiting the Pt content in the catalyst to less than or equal to about 0.5 ppm. NOx emissions, NO to NO2, produced through this process may be equal to or less than 25 ppmv. The process may also include adjusting the metal content of the feedstock for such metals as antimony, nickel, or vanadium. Additional variables for reducing NOx emissions that may be used in conjunction with this process may include increasing the flue gas residence time, injecting NH3 into the flue gas, adding or using NOx-reducing catalysts, increasing stripping of the catalyst, and increasing the catalyst zeolite to matrix ratio.

  • Patent number: 7910627
    Abstract: Suppression or enhancement of various properties of a liquid fluid is aimed by improving uniform dispersion of nanoparticles by means of making a state in which no oxidized film exists on the surfaces of the nanoparticles to be dispersed in the liquid fluid. The location of the liquid fluid is confirmed with ease by enhancing the brightness of light emission of the fluid through uniform dispersion of the nanoparticles in the liquid fluid containing a material having a flame reaction. In this way, as to liquid fluids utilized in various industries, it is possible to offer a technology to desirably enhance or suppress a property desired to be enhanced and a property desired to be suppressed among various properties that its constituents have.
