A portable air cooking apparatus for use in cooking ovens to create air currents which transfer heat to cooking food stuffs to promote more rapid and more uniform cooking or baking as described. The portable air circulating apparatus is intended to sit on the top cooking rack of a conventional oven and blow air down on food being cooked beneath it on the lower rack.

Portable oven air circulator

A portable, high-pressure, power washing system is described which includes an electric motor driven gear pump where the electric motor is effectively water cooled by virtue of being contained in a thermally conductive housing surrounded by an insulating water jacket through which the water being pumped is made to flow before reaching the pump's inlet port. The pump is driven through a gear reduction mechanism such that a relatively inexpensive, single-phase, series AC (universal) motor normally operating at a high rpm can be employed. By proper dimensioning of the pump chamber relative to the drive and idler gears and by providing a flow divider at the pump chamber's discharge orifice, high pumping efficiency is obtained. Completing the assembly is a discharge wand for directing the high pressure water at the surface to be cleaned and for controlling the on/off state of the pump's drive motor.
