Abstract: In an induction heater, preheated, pressurized air is further heated in the heating cabinet and also drawn into the coil tube via a suction fan. The simultaneous pulling and pushing of the twice-heated air through the tube provides superior air flow to pick up more moisture from the can ends being dried. The tube ends rest on upwardly concave collars and are held in place by gravity, with a single screw acting as a stop above to prevent upward movement. Removal requires only removing the single screw at each end then lifting the tube straight up out of the cabinet, which is facilitated by providing a hinged cover on the cabinet.

Abstract: A microwave oven which accepts user-placement of a cook item on a turntable accessed through a usually front-facing door. The turntable is rotated during a preset cook-time. The turntable returns to the original user-placement situation near the door and concurrently stops at the end of the cook-time. This results in a simultaneous end of turntable rotation and an end of cooking, enabling the cook-item to be conveniently reparked adjacent with the access door thereby enabling safe and convenient removal immediately upon completion of the cook-time. The cook-time and the turntable operational and reparking parameters are factored to enable a maximum extent of turntable rotation during the cook time and still assure the return to the original starting location concurrent with cook-time completion.

Abstract: A roasting oven includes an enclosure coupled to a source of microwave RF energy, an operable door for sealing the enclosure for RF, the operable door having a viewing aperture which prevents the escape of RF from inside the chamber. A rotating support has an axis which is perpendicular to the viewing aperture such that the progress of roasting may be viewed through the viewing aperture and into a food container placed in the rotating support. The applied power of the microwave RF source and the rotational velocity of the rotating support are selected to provide uniform or wide spectrum roasting of the food item. A roasting profile may include a roasting interval during which the microwave RF source and rotating support are both energized, and subsequently a cool-down interval where the microwave RF source is disabled and the rotating support continues to rotate.
