Abstract: A heating device for mounting in a window opening, particularly useful for vehicles, camper shells, and other enclosures, which includes a mounting plate; air intake and exhaust tubes, a burner contained within a sealed housing, an external fuel source, and a connecting line between the fuel source and the burner. The lower portion of the mounting plate rests upon the window sill and an upper portion engages the outer surface of the window framework to make the device useable for both vertically and horizontally movable windows. The sealed housing, which includes a cooking surface, precludes noxious fumes or explosive fumes from escaping into the confines of the area being heated. The external fuel source, preferably a portable propane tank, rests on the ground outside the enclosure, as an additional safety factor. A heat deflector, pivotal over the top surface of the burner housing, disperses the heated air to prevent overheating of the ceiling and also serves as a safety guard.

Abstract: The invention is concerned with a cooking range, especially suitable for mobile homes, which utilizes gas burners, where the exhaust gas draft is held substantially constant and the exhaust duct temperature is kept below a critical temperature by providing temperature-regulated cool air openings on the exhaust gas duct. Reliable regulation is accomplished by closures controlled by bimetallic springs positioned in a swivelable manner in the cool air openings so as to act on the closure flaps, and the closure action further improved by restoring springs exerting pressure on the outside of the closures.

Abstract: Disclosed is a gas-fired cooktop for a range which provides high thermal efficiency and low emissions of air pollutants, particularly low levels of NO.sub.x. The cooktop includes a perforated tile burner which radiates infrared energy upward at a high flux rate to rapidly quench burner gas temperatures and inhibit the formation of NO.sub.x. A perforated glass-ceramic jet plate positioned between the burner and a cooking vessel transmits most of the radiant infrared energy from the burner to the vessel and also forms jets of combustion products which are directed against the bottom of the vessel for convective heating. Thermal efficiencies of up to about 70 percent and NO.sub.x emissions as low as about 15 parts per million are achieved by the cooktop.
