Abstract: Energy systems in different industrial applications including automotive applications experience between 20 to 50 percent of raw energy input as waste heat. in the form of hot exhaust gases, hot cooling water and lost heat from hot equipment surfaces including heated products. Continued efforts to improve systems energy efficiency, recovering waste heat losses provide attractive opportunities for reduced emission and less costly energy resources. This invention introduces other methods for higher performance of existing energy consuming systems by optimizing the performance of some of the system modules that contributes to the waste energy. in turn reduce energy consumption of these systems, reduces its operating cost, damages to the population health by reducing pollution improving the environment quality, and also reduces the cost of health care.

Abstract: A rollable support for a paint supply including a roller tray, or a 5-gallon pail, has a support wall that will receive the paint supply desired. The support wall is mounted on suitable rollers at least one end that engages a surface to permit moving the paint supply support across the surface. A pair of non-rolling feet are connected to the paint supply support through pivoting link so that the feet can be moved from a position wherein they engage the surface and lift at least one end of the paint supply support so the rollers at that end of the paint supply support are lifted off the surface, the feet are movable a position wherein the feet clear the floor and the rollers support the paint supply support. As shown, rails forming parallel links comprise the feet and both ends of the paint supply support are raised and lowered. The rails provide a stable mount for the paint container support and any supported paint container when they are lowered.
