Abstract: A cooking device may be a combination gas-powered grill and pellet-burning smoker. The combination gas-powered grill and pellet-burning smoker may include an enclosure and a plurality of components may be disposed in a plurality of levels within the enclosure. The plurality of components, when disposed in the plurality of levels, may be disposed in a vertically stacked configuration. The plurality of components may include a burn pot, a diffuser, a drip tray, one or more gutters, one or more gas-powered burners, one or more heat tents, and/or a grilling surface. One or more of these components may be disposed in a housing or a cooking chamber.

Abstract: A cooking device may include a cooking chamber. A first gas-powered heat source may include one or more burners disposed in the cooking chamber. A second solid fuel burning heat source may include a burn pot disposed in the cooking chamber, and the burn pot may be spaced below the burners of the first heat source in a vertically stacked configuration. A drawer may be movable between an open position and a closed position relative to the cooking chamber. The drawer may include a drip tray that is disposed between the burners of the first heat source and the burn pot of the second heat source when the drawer is in the closed position. The drawer may allow the drip tray to be at least partially removed from between the burners of the first heat source and the burn pot of the second heat source when the drawer is in the open position.

Abstract: A cooking device may include a cooking chamber and a drip tray may be disposed within the cooking chamber. The drip tray may include one or more portions such as a first portion, a second portion, a third portion, and a fourth portion. The first portion and the second portion may be disposed in an angled configuration, such as a V-shaped configuration. In addition, the third portion and the fourth portion may be disposed in an angled configuration, such as a V-shaped configuration. The second portion and the third portion may be disposed in an angled configuration, such as an inverted V-shaped configuration. The drip tray may be sized and configured to control at least a portion of a flow of thermal energy within the cooking device.

Abstract: A combination gas-powered grill and pellet-burning smoker may include a cooking chamber and a cooking structure may be disposed within the cooking chamber. A first heat source may include one or more gas-powered burners disposed in the cooking chamber, and a temperature sensor may be disposed at least proximate the burners. A second heat source may include a burn pot disposed in the cooking chamber and a temperature sensor may be disposed at least proximate the burn pot. A controller may be in communication with the temperature sensors, and the controller may instruct a feed system to feed more pellets to the burn pot when a temperature at least proximate the burners is less than a selected temperature and a temperature at least proximate the burn pot is less than a selected temperature.

Abstract: A cooking device may include a single cooking chamber and two different fuel systems to warm, prepare, and/or cook foodstuffs within the single cooking chamber. The cooking device may also include a heat and/or smoke distribution system. The heat and/or smoke distribution system may include a gas heat source at least partially disposed within the cooking chamber and a solid fuel heat source at least partially disposed within the cooking chamber. The gas heat source and the solid fuel heat source may be disposed in a vertically stacked configuration, and a diffuser may be disposed between the solid fuel heat source and the gas heat source. A drip tray may also be disposed between the solid fuel heat source and the gas heat source, and the drip tray may include one or more openings to control the flow of heat and/or smoke within the cooking chamber.

Abstract: The dual-function impeller can be rotated in molten metal in a direction of rotation, as part of a rotary injector. The impeller can have a body having an axis, a plurality of blades circumferentially interspaced around an axis, and an aperture coinciding with the axis. The blades having both a radially extending portion facing the direction of rotation and collectively generating a radial flow component upon said rotation, and a slanted portion also facing the direction of rotation, inclined relative to a radial plane, and collectively generating an axial flow component directed away from the rotary injector upon said rotation.

Abstract: A rotary injector comprising an elongated shaft having a proximal end and a distal end, and an impeller at the distal end of the elongated shaft, the elongated shaft and the impeller being collectively rotatable during operation around an axis of the shaft, the rotary injector being hollow and having an internal supply conduit extending along the shaft and across the impeller, the supply conduit having an inlet at the proximal end of the shaft, a main portion extending from the inlet to a discharge portion, the discharge portion extending to an axial outlet, the discharge portion having a narrow end connecting the main portion of the supply conduit and a broader end at the axial outlet.

Abstract: A chair may include a seat, a chair back and a frame that may be connected to the seat and/or chair back. The chair back and the frame may include engaging portions and/or receiving portions that may be sized and configured to contact, abut, engage and/or interlock with each other to connect the chair back to the frame. The engaging portions and/or receiving portions may be sized and configured to connect the chair back to the frame using a friction, interference and/or snap fit.

Abstract: A table may include a table top and one or more leg assemblies. The table top may include a downwardly extending lip. The table may also include a frame, and the lip may include one or more receiving portions sized and configured to receive a portion of the frame. The receiving portions may also be sized and configured to receive a portion of a leg assembly. The table top may be constructed from molded plastic, such as blow-molded plastic, and the receiving portions may be integrally formed in the table top during the molding process.

Abstract: A table may include a table top and a frame. The frame may be connected to the table top using one or more fasteners. When a force is applied to the table, such as a force that draws the frame away from the table top, the fasteners may contact and/or engage one or more stops, which may help resist the frame's movement away from the table top and may help prevent damage to the table top.
