Abstract: An apparatus and method for cooking, heating, or drying in which, as items or materials are conveyed through a heating chamber by a linear, spiral, or other type of conveyor, hot combustion product gases are delivered upwardly through an upwardly extending first annulus or other flow gap which is closest to the conveyor. The hot combustion product gases are then delivered downwardly through the heating chamber into contact with the items or materials on the conveyor. Next the combustion product gases are delivered from the lower portion of the heating chamber into the lower portion of a second annulus or other flow gap or passage. The second flow gap or passage is separated from the heating chamber by the first annulus or other flow gap. Subsequently, the combustion product gases are delivered upwardly through the second flow gap or passage.

Abstract: Device for mounting a forced-air burner 2 to a combustion chamber housing 4, having an attaching section to attach the device to a combustion chamber housing 4 demarcating a combustion chamber or to a unit 5 located on a combustion chamber housing 4 and a seating section to absorb forces and/or moments caused by a forced-air burner 2 located on the device.

Abstract: An open “funnel shaped” Inner Burner inside an open top Outer Casing. The casings closed base has a central hole accommodating the burners small open bottom Ash Exit. The space between the Inner Burner wall and Outer Casing wall forms an Annular Air Plenum that's supplied by an electric variable speed blower. Air enters the Burner Combustion space through perforations in the Burner/Plenum wall. This ensures rapid ignition and controls combustion rate (Temp). This also precipitates ash from burner Ash Exit, through the Ash Chute and into Storage Container fitted to outer casings base. A Radial diffuser centered on the heating surface provides a variable speed Lateral Air Sheet between heating and grill surfaces, instantly blowing “Smoke and Flare-Ups” to the outer burner perimeter. Unit is designed as a “Drop-In” unit to fit a manufacturer BBQ cart suitably equipped to specify basic installation requirements.

Abstract: The present invention is directed to the use of starch phosphate esters as an expansion and/or texture aid in food or industrial products. The invention further provides the formulations and improved expanded products containing starch phosphate esters, particularly extruded breakfast cereals and snacks.

Abstract: The efficiency of a wood burning stove is enhanced in a number of different ways. The first is a means to first preheat air in the lower part of the airspace in the jacket before the air passes through heat exchange tubes in the firebox. The second is to discharge the hot air in the upper part of the jacketed airspace along with the hot air from the heat exchange tubes into the enclosure to be heated. The third is to deflect the discharged hot air downward to decrease the temperature differential from floor to ceiling in the enclosure being heated. The fourth is to deflect the fire and hot gasses from the firebox away from the flue so that they must pass parallel in heat exchange relationship with the top of the stove before they can enter the flue. A fifth is to provide a second grate below the heat exchanger tubes, which act as a first grate, to catch burning embers which fall between the tubes of the first grate and provide complete combustion of the embers.

Abstract: An air tight wood burning stove (10) for heating a designated space comprises a housing (12) having an access opening (50) in the front wall (14) thereof and at least one glass panel (64) containing door (54, 56) hingedly mounted on the front wall for closing the opening (50). A latching mechanism (60) on the door (54, 56) engages with undercut flange means (52, 53) surrounding opening (50) for positively maintaining the door (54, 56) in the closed position. A firebrick lined combustion chamber (34) within the housing receives logs through opening (50) for burning and the production of hot combustion gases. An air chamber (48) is formed within the housing (12) in air flow communication with the combustion chamber (34) for feeding air thereto through openings (94, 96) in the air chamber walls (46, 90).

Abstract: Three elements are secured together in new and unique fashion to form a heating unit, movable and installable as an integral unit and capable of obtaining maximum BTU's from the fuel used. These elements are (1) an outer jacket, which defines the design and outline of the heater, (2) an inner jacket, forming with the outer jacket a residual burning chamber, narrow in cross section and relatively high in vertical extent to provide maximum heat transfer surface, and (3) an A- or tent-shaped fire box or combustion chamber, enclosed by and secured to the inner and outer jackets. The tent-shaped fire box extends from the extreme lower end of the heater to its upper limit. The edges of the walls of the fire box are secured to outer and inner jackets in sealed relationship, dividing the areas within the heater into heat producing and heat conducting areas and clean air passageways. The configuration of the inner jacket 14 is an incomplete cylinder.

Abstract: An inner shell is incorporated within an outer shell and is of smaller dimensions to provide side spaces for the upward flow of heat, a top space communicating with an outlet, and a rear space having a V-shaped baffle therein causing upward flow of heat in the rearward area to be circulated and slowed for increased heating efficiency. An extension is attachable to the baffle for extending it upwardly and forwardly to control the flow of heat at the baffle. The inner shell has an imperforate tray extending from side to side and arranged to be moved forwardly through an opening in the inner shell and providing a natural forced flow of heat around it from the bottom for heating room areas.

Abstract: A stove having a combustion chamber surrounded by four sides and a top and having a warm air conduit extending between opposite sides and opening outwardly of at least one of the sides. Where the stove is to utilize natural convection, the conduits open outwardly of both the sides of the enclosure. An opening is provided in the top or bottom of the warm air conduit remote from its outlet or outlets for effecting draft thereto. A preferred embodiment has two such heating conduits at right angles to each other and with an opening therebetween to further increase draft through the conduits. In the case of forced convection, the conduits need only open from one of the sides.
