At least one upper rib and a housing of the fan are adapted to form a boundary between the middle compartment and an upper compartment.

Abstract: A ceiling fan filter for filtering the air in a room having a ceiling fan is made from at least one layer of resilient polymeric fiber filter material. Each layer has a length, a width, an upper surface, a lower surface and two side edges which extend along the length of the layer. A narrow compressed strip is formed in the filter material by compressing and heating the layer of filter material so that the filter material is fused together. The compressed strip causes an expanded thickness of the side edges to increase the effective filter surface area of the filter and gives the filter a semicircular cross-sectional shape perpendicular to the length of the filter. An adhesive layer is joined to the lower surface of the filter to attach the filter to the fan blade of a ceiling fan.

Abstract: Rotatable circular plates are stacked apart to form thin air layers therebetween. Rotation of the circular plates moves air over an air treatment material: catalyst or adsorbent. In one embodiment, the air treatment material is affixed to the surface of the circular plates. In another embodiment, the circular plates are formed from the air treatment material. The increased velocity of air relative to the circular plates causes separation of laminar flow, promotes boundary-layer turbulence near the plate surfaces, and promotes propagating stall in the air layers. These phenomena enhance the contact between the flowing air and the air treatment material.

Abstract: An indoor air purifier has a base and a container on the base with a layer of soil supported above a lower water bath occupying the bottom of the container. The container is fitted on top of the base such that the container can freely rotate upon the base. Room air is drawn into the base and is passed from the base into the bottom of the container through a duct connected between the two. Air passing from the base is directed downwardly into the water bath before passing upwardly into the soil layer. The air passes through the soil layer and is discharged from the soil's surface back into the room. Contaminant gases and particulates are removed from the air through contact with the soil layer and are metabolized by microorganisms contained within the soil, producing carbon dioxide and water. The water bath humidifies the air being passed through it and maintains a stable degree of moisture in the lower portion of the soil layer.

Abstract: A vehicle air freshener is quickly and easily installable and removable from an outlet grille of the vehicle ventilating system. The air freshener includes a tube filled with a fragrance saturated absorbent material. The tube has a sufficiently small diameter to pass through the typical opening in a vehicle interior ventilation outlet grille, and includes a thin, elongate extension and handle which is wider than the grille opening, to preclude passage of the handle through the grille opening.

After opening the scent passage seal, the air freshener is inserted into the ventilation grille opening and is prevented from falling into the ductwork of the ventilation system by the handle which is caught on the outside of the grille, thereby substantially concealing the air freshener.

Abstract: A process and apparatus are provided to treat and dispose of medical waste materials to thereby enhance public heath and social hygiene. The medical waste material is sealed in a suitable nonflammable and long infrared radiation pervious container. The container with the waste material therein is subject to long infrared radiation for a sufficient period of time to heat the waste material to sterilizing temperature levels.
