Abstract: According to one example, a convection oven comprises a cooking chamber having a front door and a rear door opposing the front door; a combustion chamber disposed below at least a portion of the cooking chamber; a side flue conduit configured to direct hot air from the combustion chamber to the cooking chamber; and a side sub-chamber with a convection fan configured to re-circulate at least a portion of the hot air within the cooking chamber, in which the side sub-chamber is disposed adjacent a side of the cooking chamber that is orthogonal to the front and rear door.

Abstract: According to one embodiment, a range for cooking includes a combustion chamber having a bottom surrounded by sidewalls that extend upward to an upper rim, a gas burner positioned at the bottom, and a platen positioned on the upper rim. The platen has an opening above the gas burner with a first flange. The range further includes a removable outer plate positioned on the first flange. The removable outer plate has an opening above the gas burner with a second flange. The range further includes a removable inner plate positioned on the second flange. The removable inner plate is circular and is made of cast iron. The removable outer plate is configured to increase the thermal resistance between the removable inner plate and the platen by having at least one of a different composition, thickness, and limited contact area than or with the platen.

Abstract: According to one embodiment, a range for cooking includes at least one combustion chamber having a bottom surrounded by sidewalls that extend upward to an upper rim. The range further includes first and second gas burners positioned at the bottom of the at least one combustion chamber, and a first platen positioned on a first portion of the upper rim. The first platen has an interior opening above the first gas burner with a first flange. The range further includes a first removable plate positioned on the first flange. The first removable plate has an interior opening above the first gas burner with a second flange. The range further includes a removable inner plate positioned on the second flange. The range further includes a second platen positioned over a remaining portion of the upper rim. The second gas burner is a linear flame source positioned under the second platen.

The range further includes at least one gas burner positioned at the bottom of the combustion chamber, and a platen positioned on the upper rim. The platen has an interior opening above one of the at least one gas burner with a first flange. The range further includes at least one removable outer plate positioned on the first flange of the platen, and an enclosure disposed to surround the gas burner and that is operative to cause preferential heating of the removable inner plate by radiation from a flame at the one of the at least one gas burner and radiation from the enclosure.

Abstract: A graftless spinal implant for mechanically attaching two adjacent vertebrae includes a body having first and second opposite surfaces. The first and second surfaces include at least one protruding member for securing the body to adjacent vertebrae, wherein the exterior surfaces of the body and the first and second protruding members include a bioactive coating. The bioactive coating can be selected from coatings such as for example, hydroxyapatite. The exterior bioactive coating facilitates the ongrowth/ingrowth of vertebral bone between the implantable spinal fusion device and adjacent vertebrae. Advantageously, spinal fusion may be achieved without the use of a bone graft and/or bone growth agents.
