A vehicle wheel and rotor assembly is provided for use with a vehicle having a disc-type brake. The assembly includes a wheel for threaded connection with an axle and a rotor. The rotor has a core section joined to an annular ring section and the core section has apertures aligned for threadably joining the rotor to the wheel. Heat pipes are embedded within said rotor core. The heat pipes provide a heat sink for the annular ring section of the rotor causing a fluid within the heat pipe to vaporize on an end of the heat pipes more adjacent to the annular ring section and to condense on an end of the heat pipe more adjacent to the wheel to transfer heat from the annular ring to the wheel.

A torque converter and clutch assembly has a piezoelectric control portion. One piezoelectric device is subjected to the transient torques transmitted to the clutch, and generates a signal in response to the transient torque. Another piezoelectric device is electrically connected with the first piezoelectric device and is expandable in response to the electric signal to initiate clutch disengagement and provide clutch slip to thereby reduce the transmission of transient torque spikes.

This invention provides methods for reducing emissions of mercury from a cement plant comprising at least a kiln (6), a particulate collection device (10), collected particulates, an exhaust gas stream (8b), a heater, and a mercury scrubber, wherein the heater and mercury scrubber are upstream from the kiln. The methods comprise directing the collected particulates through the heater, to form volatilized mercury species from the collected particulates; directing the collected particulates from the heater downstream toward the kiln; and directing the volatilized mercury species to the mercury scrubber. The exhaust gas stream (8c) exits the particulate collection device and is not directed into the heater. Optional steps include injecting a mercury sorbent at one or more points between the kiln and the particulate collection device.

This invention provides methods for reduction of mercury emissions from cement plants. In one method, a powdered activated carbon sorbent is injected into a gas stream of a cement plant at one or more points after the kiln and before the particulate collection device of the cement plant. Also provided is an apparatus for decreasing emissions from a cement plant, which apparatus comprises two or more beds in a series comprising a first bed which is a moving bed, and one or more remaining beds which are fixed beds, each fixed bed comprising at least one sorbent which is able to absorb at least one of mercury, hydro-carbons, and hydrochloric acid. Another method for reducing emissions from a cement plant employs the apparatus just described.

This invention provides a method for reducing mercury emissions from a cement plant comprising at least a particulate collection device and a preheater tower comprised of one or more preheater cyclones. The method comprises injecting pulverized coal into at least one preheater cyclone of said cement plant.
