Abstract: A modular ceiling fan housing unit designed to create a focused column or columns of downwardly moving air such that there is little deflection when the column or columns of downwardly moving air arrives at the ground level. The modular ceiling fan housing includes an elongated body element having a fluid impelling device to create the downwardly moving air. At least one plate disposed within the elongated body element directs the downwardly moving air into columns. The modular ceiling fan housing unit may be coupled to another modular ceiling fan housing unit to provide additional columns of downwardly moving air. The modular ceiling fan housing units may be coupled in various configurations, depending on the type of application. Furthermore, the modular ceiling fan housing unit or multiple modular fan housing units may be coupled to an elevated structure located either above or below the housing units.

Abstract: A wastewater collection system is provided with a gas withdrawal vent including a gas suction apparatus. The gas is preferably withdrawn at a rate in excess of the gas production by microbes in the wastewater collection system so that a slight negative pressure is created in the immediate vicinity of the gas withdrawal vent. A gas mixing chamber is coupled to the fan or blower to receive the gas withdrawn from the wastewater collection system. An ozone generation apparatus is also coupled to the gas mixing chamber that is adjusted to provide sufficient ozone to react with any noxious or malodorous components of the withdrawn gas. A reaction conduit is provided at an output of the gas mixing chamber to receive the withdrawn gas and ozone. The reaction conduit has surface features assuring turbulent flow of the gasses through the length of the conduit.

Abstract: An apparatus for producing ultraviolet light at wavelengths capable of interacting with atmospheric oxygen to generate a predetermined amount of ozone including a lamp having a tube including a first section capable of emitting UVA light without emitting UVB light and a second section capable of emitting both UVA and UVB light, and a generally tubular sleeve capable of attenuating UVB light mounted to the tube for sliding movement along and covering a selected portion of the second section and attenuating a predetermined amount of UVB light emitted therefrom. An element for fixing the sleeve to the tube at a desired position are provided, and the sleeve may include a plurality of individually slidable sleeve segments.

Abstract: Ozone generating apparatus designed for installation into airflow ducts or other air handling structures of housing units or other buildings includes a porous gridwork, mesh, or other minimal airflow obstruction support with an ozone generating plate positioned to release ozone into passing air. A second housing attached adjacent to the first housing contains electrical circuits for developing an electrical potential applied across the ozone generating plates positioned in the first housing. The second housing has a control surface that includes a control mechanism for controlling the electrical circuits. The second housing also accommodates a first switch for activating and deactivating the electrical circuits that generate an electrical potential across the ozone generating plates.

Abstract: Ozone generating apparatus adapted for quick installation into existing structures includes a plurality of housings adapted to be coupled together in at least two different relative orientations to permit adaptation of the ozone generation apparatus to the relative direction of air flow through an air handling conduit, with the housing containing ozone generating plates projecting rearwardly from the back surface of the housing containing the power and control circuitry for projection through an opening in the air handling conduit to a position wholly within the air handling conduit. The apparatus also includes ozone generating and air moving elements enclosed within a generally rectilinear housing having a closed top, four side walls depending from the top and terminating in a coplanar lower edge defining an open bottom, the lower edge being sized to be supported upon rails forming a grid work of a conventional suspended ceiling.
