Abstract: A device for burning gaseous fuels in which the stoichiometric quantity of air for complete combustion is mixed with the fuel gas by entrainment. The fuel gas is discharged through openings arranged in a two dimensional array and the openings are so spaced from each other that the turbulent jets merge in a plane in which just the right amount of air has been entrained into the jets by turbulence.

Abstract: An oven broiler is provided with an elongated stoichiometric burner having two rows of apertures from which emerge free turbulent gas jets entraining the stoichiometric quantity of combustion air before merging on account of the spacing between the apertures being proportional to the aperture diameter, the ratio of the Rankin temperature of gas and air; a curvilinear radiator shield is heated by the combustion products and directs radiation away from the burner, and a second shield is heated by the combustion products flowing off the first shield.

Abstract: A burner for use on a gas range top in which the burner combustion products heat the bottom surface of a ceramic-glass plate. My stoichiometric burners provide optimum performance when they are used to heat surfaces which operate at low temperatures such as a water heater or a steam boiler.There are, however, other applications wherein the surfaces to be heated must operate at high temperatures such as a broiler for a gas range.A new principle stoichiometric equation is provided for the spacing of the apertures in the top surface of the burner chamber when the stoichiometric burner is exposed to a thermal radiation field.A new principle blower for forcing the combustion air through a heat exchanger is now described in U.S. Pat. No. 3,859,009.

Abstract: A burner chamber with a flat top is provided with an hexagonal array of specifically spaced apertures through which are discharged free turbulent jets into a mixing chamber in which the fuel gas is mixed by entraining heated air. Combustion occurs above the plane where the jets coalesce and a ceramic top is provided on top of the combustion chamber for heating by combustion products. These hot jets are brought in heat exchange relationship with air flowing into the mixing chamber; radiation from the ceramic top heats the burner chamber.

Abstract: Apparatus for thawing frozen food without cooking by producing a homogeneous mixture of steam and air with a dewpoint of 170.degree. F or lower and a mixture temperature below 212.degree. F, external to a thawing chamber, and forcing the steam-air mixture to flow towards the top and bottom surfaces of frozen food supported in the thawing chamber.Apparatus for reconstituting frozen food in three distinctly different steps:1. A hot gas heats a food chamber to the serving temperature of food. The food chamber has a multiplicity of apertures positioned in the top and bottom walls of the chamber.2. Water is vaporized by adiabiatic transformation of a portion of the sensible heat in the hot gas to the latent heat of the water vapor. The water vapor is then intermixed externally to the food chamber with the hot gas in order to produce a vapor aeriform gas which has a temperature substantially higher than its dewpoint.

Abstract: A circuit for protecting a gas burner is described to shut the flow of gas off, if the air blower fails.
