Abstract: A portable air circulating apparatus for use in cooking ovens which is used to create air currents in the oven which transfer heat to cooking foodstuffs to promote more rapid and more uniform cooking or baking, the apparatus including a motor, fan blade and housing of metallic materials selected from a class of heat resistant materials.

Abstract: A portable turntable apparatus for use in microwave ovens which is used as a supporting base for a container of food which is cooked within the oven and adapted to gradually rotate the same, the apparatus including a motor including metallic materials which motor is mounted in and enclosed by a metal housing and an outer enclosure comprising a cover and base of non-metallic material to prohibit electrical arcing between the motor and the oven walls. The housing is provided with smooth outer surfaces and a minimal sized aperture opening to allow a driving connection between the motor and the enclosure cover. The motor is a spring motor having an improved centrifugal governor.
