Abstract: A microwave container which morphs from a relatively microwave transparent condition to a relatively microwave blocking condition in response to microwave irradiation. The container wall section has a plurality of discrete, unconnected microwave reflective material elements initially permitting the transmission of microwave energy into the container and either a microwave absorptive material or a thermally responsive material active to coalesce the microwave reflective material elements into a connected array or pattern to block the transmission of microwave energy from entering the container after absorbing a predetermined amount of microwave energy.

Abstract: A combined transformer and motor having a continuously energized primary winding producing a continuous output voltage from a transformer winding and a selectively enabled motor shaft rotational output which is selectively actuated by powering a further primary winding.

Abstract: A plastic microwave oven cavity assembly formed of top and bottom members having a microwave impermeable coating on the interior thereof and a side wall member having a microwave impermeable coacting on the exterior thereof with the members joined by seams which maintain the integrity of the microwave impermeable coacting to contain microwave energy within the cavity.
