A vehicular atmosphere cleansing system utilizes a regenerative wheel having flow channels extending through the wheel coated with an adsorbant. An atmosphere stream passes through a first position dependent portion of the wheel where VOC's including HC's are adsorbed while a heated atmosphere stream passes through a second position dependent regenerative portion of the wheel whereat VOC's are desorbed. The adsorbant is activated carbon having particles of micropore size adhered to the substrate...

Method and apparatus for treating the atmosphere to lower the concentration of pollutants, such as ozone, hydrocarbons, nitrogen oxides, sulfur oxides, carbon monoxide and the like, therein in which ambient air is passed into operative contact with a stationary substrate such as an automobile at rest, a billboard, an air conditioning unit, a transportation tunnel and the like, the stationary substrate having at least one ambient air contacting surface having a pollutant treating composition, suc...

Method for treating atmospheric pollutants by contacting the atmosphere with a catalyst composition or adsorptive material coated on the surface of a substrate, preferably a motor vehicle radiator, in which the catalyst composition, preferably including a base metal, precious metal, or salts/oxides thereof, or adsorptive material, preferably including a zeolite, Group IIA alkaline earth metal oxide or carbon, is protected from degradation by harmful contaminants such as solid or aerosol particul...

Method for cleaning the atmosphere by adsorbing pollutants, e.g., hydrocarbons, ozone, carbon monoxide, nitrogen oxides, sulfur oxides, etc., contained in the atmosphere. The pollutant-containing atmosphere is contacted with an outer surface of a substrate, e.g., radiators, condensers, charge air coolers, transmission coolers, etc., which has been coated with an adsorptive material such as zeolites, molecular sieves, carbon, etc. The coated substrate is protected with an overcoat of at least one...

To determine a gas status (wind direction, wind speed), which is detailed in terms of space and time, from meteorological observation data, such as meteorological GPV, which are rough in terms of space and time, initial conditions and boundary conditions set based on the meteorological observation data are incorporated into differential equations for analysis of atmospheric phenomena, and computations are performed by a parallel computer 11. For the computations, a computation period is divided,...

A method for reclamation of atmospheric water uses a water reclamation chamber (1) with water reclamation cells (2) and variable high-performance blowers (3). In this occurs by means of cooling collectors (6) during the nighttime the cooling of a coolant stored in a cooling resorvoir (7), and during the daytime operation by means of solar collectors (8) occurs the heating of a further fluid stored in a heat reservoir, so that the coolant that is cooled during the night for the purpose of water r...

The present invention provides a device for modifying an atmosphere in proximity to the device, the device comprising a sachet comprising a semipermeable material, and a composition including a mixture of acetylsalicylic acid and sodium bicarbonate contained within a cavity of the sachet. The invention further provides methods for modifying an atmosphere comprising placing a mixture of a carboxylic acid and a base in the atmosphere, wherein the atmosphere has a sufficient level of water vapor su...

A package for storing oxygen sensitive goods includes a first web in the form of a tray which may include flanges, a valve or valves, carbon dioxide, a good or goods, such as red meat or other oxygen sensitive food and non-food products and a second web sealed to the tray in the form of a gas impermeable film to which has been fitted a one-way valve. The pressure within the package increases as a gaseous modified atmosphere is introduced through the one-way valve in the tray. The oxygen within t...

A method and apparatus for providing a clean respirable atmosphere in a clean room. A liquefied breathable gas is supplied from a source thereof and filtered. The filtered liquid is vaporised and the gas produced by the vaporisation is filtered. Thereafter the filtered gas is introduced into the clean room.

A method of extended shelf life packing of a food, wherein the food comprises meat, consists of the step of packaging the food by sealing the food in a non-barrier, oxygen permeable, flexible package. The package comprises plastic film and the atmosphere sealed within the package is pure oxygen (100% O.sub.2). The plastic film may comprise polyethylene film or low density polyethylene film.
