Abstract: Disclosed are a pollutant capturer and mobilizer and method of mobilizing a polluted gaseous substance from one location towards another location and capturing one or multiple types of polluting substances, such as CO2, from an atmospheric body of polluted gaseous substance or from exhaust of vehicles, chimneys, or stacks and thereby combat the negative health, environmental, and economic impacts of the of the polluting substances on communities. Wet or dry embodiments of the pollutant capturer and mobilizer utilize wet or dry pollutant capturing components, respectively, to capture one or multiple types of polluting substances from a body of polluted gaseous substance. Flow establishing devices can be used to set the body of polluted gaseous substance in motion through the pollutant capturing component. The pollutant capturer and mobilizer may also be mounted on any type of vehicles, with or without using flow establishing devices.

Abstract: An essential oils diffuser with a micro air pump providing between 500 and 1500 Pa of pressure with a consumption of between 0.2 and 1 Watts may be used to push air into essential oils or an essential oil solution to diffuse and expel the oils into the air, while keeping the oils away from the air pump, preventing the oils from shortening the life of the diffuser. The diffuser may include a power supply and a controller to regulate the operation of the diffuser.

Abstract: An extractor that may have a diffuser located a vacuum chamber to which a vacuum is applied by a vacuum pump. The diffuser has cavity and at least one diffuser aperture, and receives a mixture of waste cleaning liquid and aspirated air. The diffuser and the vacuum chamber separate the waste cleaning liquid from the aspirated air. A suction hose and pump may remove the separated waste cleaning liquid from the vacuum chamber.

Abstract: The present invention is an exhaust gas purifier that can effectively remove soot from exhaust gas of a diesel automobile, for example, a truck and a bus. The present invention has a simple structure, and can effectively remove from exhaust gas the following exemplary pollutants, carbon monoxide, nitrogen oxides, sulfur oxides and hydrocarbons.

Abstract: An apparatus for removing particles and/or other undesirable components from a gas stream includes a container containing a liquid, an inlet for the gas stream permitting wetting of at least a portion of the gas stream, and an outlet from the container for cleaned gas. The inlet and/or the outlet includes condensing means for cooling desired fractions of the gas stream and/or cleaned gas. The liquid may be such as to wet the particulates, thereby retaining them in the liquid while the gas passes through the liquid to the outlet. Methods for removing particulates and/or other undesirable components from a gas stream are also provided.

Abstract: A method and apparatus for filtering an air stream with an aqueous froth are provided. The process includes: passing a contaminated air stream through a diffusing sieve, into an aqueous solution in an expansion chamber; generating, maintaining, and containing an aqueous froth between the liquid-bath reservoir and a saturated fiber element; and continually saturating a coarse-fiber element with liquid from the aqueous solution. The froth is generated and maintained, and the fiber element is saturated, by controlling the dynamic interface between the contaminated air stream and the liquid-bath reservoir. The apparatus for filtering an air stream includes: an air filter device that incorporates a liquid-bath filter initial stage; an aqueous-froth filter second stage; a constantly saturated, coarse-fiber filter as a combined third stage and froth-limiter; and a moist, fine-fiber filter as the final stage.

Abstract: An object of the present invention is to provide an exhaust gas purifier which can effectively remove soot from exhaust gas of a diesel automobile such as a truck and a bus and the like, and which has a simple structure, and an exhaust gas purifier in which carbon monoxide, nitrogen oxides, and sulfur oxides and the like can, in addition to hydrocarbons, be effectively removed from exhaust gas.

Abstract: A filtration device particularly for use with vacuum cleaners used for collection of fine liquid spray particles which tend to clog porous solid filters. The device utilizes readily replaceable liquid as a filtration medium with air being forced into the liquid then released for additional multiple liquid contacts. The device further includes horizontal baffles with air access apertures wherein one or more of the baffles can be perforated, mesh or absorbent therein which are positioned above the surface of the liquid, with a vacuum being applied to the area. This redirects liquid spray particle laden air into filtration contact with liquid multiple times wherein filtration efficiency is in excess of 99%. The perforated, absorbent or mesh baffle removes remaining mist or spray from the system or device.

Abstract: A vacuum cleaner assembly comprising a main housing, a primary filter system, and a secondary filter system. The main housing includes an inlet and an outlet. The primary filter system filters the air prior to being exhausted outwardly through the outlet. The secondary filter system is placed in downstream airflow from the primary filter system and provides additional filtering of the air prior to being exhausted to atmosphere.

Abstract: A filter assembly for a vacuum cleaner that includes a main housing having an inlet and an outlet. A motor moves air from the inlet to the outlet, and a first filter is arranged between the inlet and the outlet for filtering the air. An inner wall and an outer wall that is spaced apart from the inner wall form a cavity between the walls. The cavity is located between the first filter and the outlet. The inner wall has an inner opening that permits air to flow from the first filter into the cavity, and the outer wall has an outer opening. A back cover is removably secured to the outer wall over the outer opening to seal the cavity and guide the air from the cavity to the outlet. The back cover includes an access opening that is removably secured to the back cover over the access opening to seal the access opening. A filter cartridge is removably disposed within the cavity.

Abstract: A vacuum cleaner assembly (10) includes a main housing (12) having an inlet (14) and an outlet (16). A motor (17a) is disposed within the main housing (12) for providing motive force to a cooling fan (17b), a blower (17c), and a separator (22). The separator (22) circulates the air and water bath (20) within a water bath pan (36) and provides, in combination with the water bath (20), a primary filter for filtering the air. A second filter assembly (24) is also provided preferably including a high efficiency filter (100 or 100a), or HEPA rated filter, for filtering microscopic dust and dirt particles that escape the separator (22) and water bath (20) and is disposed after both the water bath (20) and the separator (22) for additional filtering of the air. Alternatively, it may be a non-HEPA rated filter (101).
