A self-maintenance planter device for the purpose of supporting, nurturing, watering, and feeding a plant organism is disclosed. The planter includes the components of a water/absorbent reservoir, a soil support plate, a water addition tube and cap, and one or more conduit wicks to accomodate bidirectional water flow between the water/adsorbent reservoir and the potting soil. The planter device is constructed to promote time periods of reversed water flow from the potting soil through the conduit wicks to the water/absorbent reservoir. Various noxious substances such as mercaptans are flushed from the potting soil into the absorbent/water reservoir, and the noxious substances are physically or chemically absorbed into the absorbent substance, thereby providing a purified environment for nurture and sustenance of plant organisms for extended time intervals.

Self-maintenance planter

An evaporative cooler apparatus and method of operation are disclosed. The invention was conceived and developed to humidify and cool the attic space between the roof and the ceiling of man-made buildings or other structures. The apparatus is comprised of an induced draft fan assembly which blows air through an evaporation bundle comprised of one or more concentric cylinders of fibrous evaporation pads. The most advantageous embodiments of the invention and optimum parameters of operation result in reduced costs for installation, for evaporation water, for electrical power, and for service and maintenance as compared with devices of the prior art.

Evaporative air cooling apparatus

A gaseous stream (such as a 'sour' natural gas stream) composed chiefly of a normally gaseous light hydrocarbon or alkane, such as methane, ethane, propane, or mixtures thereof, containing undesirable constituents, impurities or contaminants, such as carbon dioxide, hydrogen sulfide, water vapor, nitrogen and helium, is mixed with a polar organic liquid, such as methanol, or an aqueous solution of said liquid, such as an aqueous solution of methanol. The resulting mixture is cooled and liquefied and the resulting two-phase liquid mixture (comprising a light phase rich in the desired light hydrocarbon and an impurities-rich heavy phase of said polar organic liquid) is extracted with said polar organic liquid to recover said light hydrocarbon in the liquefied state, e.g. as liquefied, 'sweet' natural gas.
