Abstract: A hybrid tubular pipe burner has a lateral flame emitted from a slot in the tubular pipe burner, the tubular pipe burner being supplemented with the placement of spaced electric heaters disposed outside the pipe burner. The electric heaters run along the length of the pipe burner but are disposed such that they stand off and away from the surface of the pipe burner. The pipe burner is configured to allow for initial gas firing and preheating. Upon reaching the required temperature, the gas firing will cease and the electric heaters will take over. The gas is used for preheating only. The continued flow of air through the pipe prevents deformation of the pipe in the pipe burner.

Abstract: The invention relates to a frame assembly for displaying a plurality of indicia and reflecting an image. The frame assembly comprises a display unit for displaying indicia, an enclosure for supporting the display unit, a mirror supported by the enclosure, a sensor supported by the enclosure, a mass storage device for storing the indicia to be displayed on the display unit, a central processing unit for processing the indicia, a signaling system for switching the frame assembly between a first and second mode of operation, a controller in communication with the sensor and central processing unit, and a power supply display unit. The frame assembly in a first mode displays desired indicia through the mirror and, upon the sensor detecting an object at a desired distance, in a second mode functions as a mirror to reflect an image.
