Abstract: A heat deflector includes a first portion having a first outer edge and a center and a first surface extending from the first outer edge to the center of the first portion. The first surface sloping downward from the first outer edge toward the center of the first portion. The heat deflector further includes a second portion having an inner edge and an outer edge. The inner edge of the second portion is adjacent to the first outer edge of the first portion. The heat deflector further includes a third portion having a third outer edge and a third inner edge and a second surface extending from the third outer edge of the third portion to the third inner edge of the third portion. The second surface sloping downward from the third outer edge of the third portion to the third inner edge of the third portion.

Abstract: An oven muffle that has at least two wall elements adjoining each other, which delimit at least some regions of an interior space that is used as a cooking chamber. The wall elements are of a glass or a glass ceramic and the adjacent wall elements are oriented at an angle with respect to one another. In an oven muffle of this invention, along with ease of cleaning, a simple structural design is achieved if the wall elements are integrally joined to one another and constitute one formed part.

Abstract: A center burn technology for a stove or dryer for the burning of solid, loose or compressed fuels, or mixtures of fuels. The stove uses a center burn draft and combustion through the combustion material. The preferred embodiment of this stove consists of at least two bins, an outer exhaust bin and inner combustion bin. A vertically placed air core combustion tube is resting within a stabilizing support collar at the top and at the bottom the tube rests inside of a tapered apparatus. The smaller opening at the bottom of the tapered apparatus provides return gas venting and easy ash drop system to ash bin or pan below. Exhaust drafts through vents between said bins at the upper portion of the inner combustion bin. The stove provides a long efficient burn with a steady combustion temperature. The stove does not require the use of electricity.

Abstract: A spark arresting incinerator apparatus for burning combustible solid materials without the release of hot embers or ash capable of igniting materials outside the incinerator includes a firebox to contain the combustion, a grate disposed across the bottom of the firebox to support materials to be burned, an ash box disposed below the firebox and grate and connected to the firebox, the ash box having at least one screened and shielded combustion air inlet, a generally pyramidal cupola disposed above and connected to the firebox, and a chimney disposed above and connected to the cupola for the exit of combustion gases from the incinerator. The chimney includes a plurality of baffle plates each extending partially across the interior of the chimney, with the baffle plates disposed in staggered offset relation to each other, and also preferably includes a spark arrestor connected to the top of the chimney.

Abstract: A method of combusting a fuel in a burn pot includes forming an ash column within the burn pot, and removing a portion of the ash column. The burn pot includes a first sidewall portion, a second sidewall portion, and a translatable plate interposed between the first sidewall portion and the second sidewall portion. The translatable plate is capable of at least two positions. The translatable plate has an opening therein corresponding substantially to a cross sectional area of an inside area of the first sidewall portion or the second sidewall portion.

Abstract: A heating device constructed for efficiently burning newspapers by converting them to a carbon-like material and then burning this material in a controlled manner to produce useful heat including radiant heat which may be employed to heat a living space, persons occupying the space, cooking foods, or the like. In one embodiment, the heating device is placed in a fireplace and in a second embodiment encompassed by this invention, the heating device is a free-standing heating device which may be used indoors or outdoors. The heating device includes a supporting structure for supporting folded newspapers in a housing having an open front with the newspapers being retained in place by side pressure exerted by damper screen supporting rods indented into the side edges of the newspapers.

Abstract: A heater closure attachment for 30 and 55 gallon metal drums which includes a main closure section provided with an exhaust stack and two depending draft inlet pipes, and a hinged section through which solid fuel is inserted, the inlet draft pipes having damper lids to control combustion and the whole attachment being in knock-down, readily portable form for assembly on the job by unskilled labor.

Abstract: A heater which burns agricultural waste as its heat source includes a combustion chamber for the waste having a bottom opening, a grate for supporting the waste, an access lid at the top and an air intake at or adjacent the top. The bottom opening is connected to an exhaust system which includes a fan for creating a downward draft in the combustion chamber causing the exhaust gas stream to leave the chamber at the bottom opening. The exhaust system also includes elements for the removal of solid combustion products from the exhaust stream and for regulating the temperature of the exhaust stream which is then usable for heating purposes.

Abstract: A method for treating a spent emulsion of oil in water used in an industrial process, in particular an emulsion of cutting oil in water is described.The method comprises at least one stage in which heat energy is supplied continuously to said emulsion for evaporating a predetermined quantity of the water contained therein and to raise the concentration of said oil in the emulsion to a value such as to enable this latter to be burnt in an industrial burner, said heat energy being at least partly provided by utilizing solar energy, and further comprises at least one stage of burning the emulsion of said oil concentration in a burner in an industrial or heating plant.
