Abstract: The present invention utilizes simple dimethylsilicone fluids of the proper viscosity/molecular weight added to modify the low temperature properties of polycyclic hydrocarbons. One preferred embodiment of a polycyclic hydrocarbon is a perhydro dimer of alpha-methyl styrene. Addition of the dimethylsilicone fluid to the perhydo dimer of alpha-methyl styrene improves the low temperature performance without degrading the requisite low shear stress shear strength properties. Low viscosity dimethylsilicone lubricating fluids combined with polycyclic hydrocarbons are suitable for use in infinitely variable transmissions providing good low temperature flow properties and high shear strength at high temperature and low contact stress conditions.

Abstract: Nanoscale chemicals based on polyhedral oligomeric silsesquioxanes (POSS) and polyhedral oligomeric silicates (POS) are taught as lubricants, mold release agents, and as additives to control the viscosity, lubrication, wear, and thermal properties of conventional lubricous materials. The precisely defined nanoscopic dimensions of POSS materials enable viscosity, miscibility, and thermal properties to be (increased) or reduced (decreased) as desired. A key feature to the successful tailoring of properties is the inherent thermal and chemical stability of the POSS/POS nanostructure and the ability to control its topology and chemical potential to match that of surfaces and other materials.

Abstract: A lubricant for a run-flat tire system includes a water soluble, or water-miscible carrier, a thickener, and a surfactant. The thickener hereof retains its rheological properties and is not subject to permanent thinning shear. The base fluid is, preferably, a water-soluble polyhydroxyl or other polyhydric compound and the thickener is preferably a clay. When admixed with a surfactant and, optionally, a lubricity agent, the lubricant exhibits long term stability and (is resistant to heat buildup.) prevents the buildup of heat in the tire assembly when the tire is in the run flat condition.
