摘要： The present invention reduces the amount of oxygen in an oxygen-containing gas within a closed environment. A selected amount of hydrogen gas is mixed with a portion of the oxygen-containing gas from the closed environment to form a first gas mixture. A catalyst exposed to the first gas mixture causes a reaction between the hydrogen and at least a portion of the oxygen therein. The resulting second gas mixture, which is returned to the closed environment, has a lower percentage of oxygen. At least one oxygen sensor is positioned in the closed environment to determine when oxygen levels in the closed environment reach a threshold level. The output signal from the sensor is used to control when and/or how much hydrogen is mixed in the first gas mixture.

摘要： An air purification system that uses laser beams to purify air. A laser beam is set to sweep across the interior of a box that is open at two ends to the flow of air. The laser beam is of sufficient strength to destroy or neutralize any dust particles, pollen, pathogens, allergens, or gasses that are present in the flow of air through the box. An air baffle box is utilized at each end of the box with the air flow to prevent the laser beam from escaping from the box. A second preferred embodiment of the present invention is the use of a fan laser beam to purify a flow of air. Said fan laser beam is suppled to a box through which air is flowing in such a manner that all air passing through the box must also pass through said fan laser beam. An air baffle box is utilized at each end of the box to prevent the escape of laser beams.

摘要： A regenerable high capacity carbon dioxide (CO2) sorbent is operated to remove substantially all of the CO2 present in either a dry, or a humid environment. The sorbent is an amine compound which is composed predominantly of secondary amine groups, and includes one or more functional nitrile groups. Primary and tertiary amine groups form a minor percent of the sorbent. The reaction product of tetraethylenepentamine (TEPA) and acrylonitrile (AN), which reaction product will be referred to hereinafter as “TEPAN” is a preferred sorbent. The addition of one or more nitrile functional groups to TEPA by reason of the reaction between AN and TEPA converts most of the primary amines in TEPA to secondary amines in TEPAN. We have discovered that the presence of predominantly secondary amines in the sorbent enhances the regenerable cyclic CO2 absorption capacity of the sorbent by more than two and one-half times, as compared to a TEPA sorbent bed; and the use of TEPAN as the sorbent bed also significantly reduces amine volatility to low levels which are immeasurable. The sorbent bed of this invention is also easily regenerable.
摘要翻译：操作可再生的高容量二氧化碳（CO 2）吸附剂以去除干燥或潮湿环境中存在的基本上所有的二氧化碳。吸附剂是主要由仲胺基组成的胺化合物，并且包括一个或多个官能的腈基。伯胺和叔胺基组成吸附剂的一小部分。四乙烯五胺（TEPA）和丙烯腈（AN）的反应产物，该反应产物在下文中称为“TEPAN”是优选的吸附剂。由于AN和TEPA之间的反应，向TEPA中加入一个或多个腈官能团将TEPA中的大多数伯胺转化成TEPAN中的仲胺。我们已经发现，与TEPA吸附剂床相比，吸附剂中主要存在的仲胺增强吸附剂的可再生的环状二氧化碳吸收能力超过2.5倍; 并且使用TEPAN作为吸附剂床也显着地将胺挥发性降低至不可测量的低水平。本发明的吸附剂床也容易再生。

摘要： A portable air purifying apparatus including a high frequency voltage booster and an anion generator. The high frequency voltage booster is comprised of a control box accommodating therein a circuit board and two batteries. The circuit board has electronic components assembled thereon to form a high frequency high voltage circuit for generating high frequency high voltage pulse currents when the batteries supply electric currents. The anion generator is comprised of a generator body accommodating therein a discharge electrode, a necklace attached to the generator body, and a terminal connector. The generator body has two air vents. The high frequency voltage booster and the anion generator may be carried around by the user. The terminal connector may be plugged into the terminal socket of the high frequency voltage booster to allow output of high voltage pulse currents so that the discharge electrode inside the generator body may discharge high frequency high voltage currents to generate many anions that may escape through the air vents of the generator body into the air so as to react with and decompose the viruses floating in the air, thereby purifying the air around the user and avoiding viral infections.

摘要： A life support system is provided for users located within enclosed areas to supply them with fresh air from a location exterior of the enclosed area, and is particularly adapted for use in emergency circumstances such as when fire and smoke fill enclosed areas. The system can be used in buildings and in aircraft and can be adapted for use with the gasper outlets presently employed on aircraft. A method for providing fresh exterior air to the enclosed area and the user includes conducting the air to an outlet for the exterior air which is located within the area, conducting the exterior air from the outlet to at least one breathing cavity of the user, and preventing the user from inhaling ambient atmosphere from within the enclosed area.

摘要： An air remediation device includes a housing including an internal chamber, an inlet, an outlet, and a potting material dividing said internal chamber into a first compartment and a second compartment. At least one hollow fiber membrane is supported by the potting material and held in the first compartment. Airborne viral particles are directed (a) through the inlet into the first compartment and then (b) through the at least one hollow fiber membrane, where the airborne viral particles are captured to produce treated air, and then the treated air is directed (c) through the second compartment before being exhausted from the housing through the outlet.
