Abstract: An air sterilization apparatus for sterilizing air that can include a fan assembly, which may be mounted in an upper-part of a room, and a UVC lamp to emit a UVGI field. The air sterilization apparatus may direct air across the UVGI field to sterilize the air. A baffle may also be provided to shield the eyes of occupants of the room from UVC energy contained in the UVGI field. The air sterilization apparatus may also include an illuminator lamp to provide illumination to a room.

Abstract: A radon decay product remover for use in a conventional, residential lamp. The remover screws into the light bulb socket of a lamp and provides a replacement socket for a light bulb. The flow of electric current to the light bulb is controlled by an on-off switch in the radon decay product remover. When used in a table lamp, an ion generator includes electrodes (from which negative and/or positive ions are emitted) that attach to the exterior of the lamp shade.

Abstract: An economical method and apparatus for the removal of airborne radon decay products from indoor environments comprising the circulation of air in the environment with a fan concurrent with generation of ions from an ion generator to create a spatial distribution of airborne charged ions and an electric field gradient which is radially directed from the ion generator. The turbulent convection of air caused by the air circulation allows the radon decay products and particles to which they attach to become more rapidly charged and facilitates molecular diffusion of the particles and radon decay products to nearby surfaces. The electric field gradient causes migration of charged attached or unattached radon decay products toward the walls of an indoor environment whereby they deposit and are removed from the airspace.

Abstract: Method for the production of hydroperoxides of hydrocarbon having no aliphatic or cycloaliphatic tertiary carbon atoms, wherein such hydrocarbons are oxidized in the liquid phase with molecular oxygen in the presence of a stabilizing agent. This method gives high hydroperoxide selectivities at high conversion levels.
