Abstract: An operable transmission comprising toothed wheels. In order to operate the transmission with a lubricant and coolant which is environmentally friendly while providing improved heat dissipation and temperature-independent viscosity, the transmission contains a mixture of water and a glycol or similar, in which graphite particles are suspended. The mixture contains 40 to 60 percent per weight of the glycol and 2 to 25 percent by weight of graphite in the form of flaky graphite particles having a grain size of less than 12 micrometers, the remainder being composed of water and other admixtures and/or additives. Also disclosed are the lubricant and coolant as well as a method for starting a transmission operated with the lubricant and coolant.
Abstract: The invention provides an apparatus for comminuting coal or other fuel solids in a shear field, and for optionally coating the solids with catalysts for combustion, liquefaction, and or gasification during the milling process. The apparatus further provides for control of water content in the solids may be controlled before, during and after the milling in order to obtain micronized solids with fine hydration layers. The output fuel solids of the apparatus can burn at low temperatures, avoiding emissions of nitrogen oxides, and they also have improved properties for surfactant-free suspension in either water or oil media, as well as for liquefaction and gasification.
