Burner kettle for asphalt paving apparatus
InactiveUS9732280B1Less maintenanceEasy access and replacementRotary stirring mixersTransportation and packagingAsphaltEngineering
A burner system for heating the material product, i.e., asphalt, includes a burner kettle designed with a thicker bottom heat transfer plate, added heat transfer oil (HTO) circulation pumps, a spiral circulation ring and heat restriction rings. The spiral circulation ring spirals up the burner kettle to move the HTO around the entire circumference of the burner kettle to eliminate hotspots. An HTO pump moves cooler oil from the top of the kettle directly across the hottest part of the bottom of the kettle, i.e., across the heat transfer plate. Keeping this zone cool will eliminate heat stress of the material. Heat restriction rings direct the heat back and forth throughout the burner kettle for increased efficiency.

An traffic light capable of utilizing both natural sunlight and artificial light for illuminating selective traffic signals. Natural light is directed to a natural light router or switch and to a color switch for providing a red, amber or yellow, and a green light for each bank of traffic light signals. A controller is coupled to the natural light router and light emitting diodes for controlling the mode of operation for operating the traffic light with either electrically powered light emitting diodes or with natural light collected by the natural light collector. A sensor detects the adequacy of the natural light, and when insufficient, causes the controller to power an LED signal light. The natural light may either be amplitude modulated or time modulated so as to provide a desired high illumination output to the desired signal light. The power consumption is greatly reduced, as well as providing a more reliable traffic light substantially independent of power line interruptions or fluctuations.
