Abstract: A contaminated gas that is to be cleaned, such as contaminated air, is passed through an adsorbent bed to remove gaseous contaminants. An enclosure having a fixed volume is then created around the adsorbent bed. Included within the enclosure is a photocatalytic gas purifier. The adsorbent bed is heated to release the contaminants into the fixed volume to create a high concentration of contaminants in the gas within the fixed volume. The now highly contaminated fixed volume of gas is recirculated through the heated adsorbent bed and photocatalytic gas purifier. The gas purifier oxidizes the contaminants at a high oxidation rate due to the high contaminant concentration level. The enclosure is then opened and the adsorbent bed, now regenerated and at its original temperature, is ready to again receive and clean contaminated gas.

Abstract: A humid gas stream is dehumidified by bringing that stream into contact with the front surface of a hydrophilic capillary condenser layer that captures the water and moves it adjacent the rear surface of the capillary layer. An osmotic layer, such as a semi-permeable membrane, is disposed on the rear surface of the condenser layer, and an osmotic fluid having a low concentration of water therein, is disposed adjacent the osmotic layer. An osmotic driving force, resulting from the water concentration gradient across the osmotic layer, transports the condensed water from the condensing layer through the thickness of the osmotic layer and into an osmotic fluid. The osmotic layer also inhibits the osmotic fluid from flowing into the condenser layer.

Abstract: Volatile organic compounds, for example organophosphonate compounds including chemical warfare agents, pesticides, and solvents, are decomposed by contacting the compounds with either a manganese oxide catalyst in the presence of visible light or a catalyst material selected from the group consisting of vanadium, vanadium oxide, manganese oxide and mixtures thereof deposited upon a catalyst support that is heated to at least 300 C. The catalyst material may be regenerated by a process selected from the washing with water, washing with a solvent, heating, exposing to light, purging with oxygen, purging with a reactive gas, exposing to microwave radiation, and combinations thereof. The catalyst composition may be used as an air filter in a vehicle, a building or a personnel protection device, such as a gas mask.

Abstract: Cylindrical heat exchangers are typically constructed of a plurality of spiral passageways created by multiple concentric annuluses, with increasing diameters, overlaying one another. Each passageway, however, typically includes a corrugated sheet between such circular layers, and the corrugated sheet acts as an obstruction, thereby decreasing the pressure of an air stream as it passes therethough. The present invention is a cylindrical heat exchanger having a plurality of spiral passageways created by a spirally wound rectangular sheet, wherein the overlapping spiral layers, that are formed by the winding the rectangular sheet, are spaced apart by a plurality of radially aligned dividers. The dividers, along with an open interface layer that is interposed between the spiral layers, maintain the constant gap between the spirals. Therefore, manufacturing the cylindrical heat exchanger with spiral rather than concentric layers improves the process of manufacturing such devices. Additionally, replacing the corrugated sheet with an open interface layer decreases the pressure drop of the air streams passing through the cylindrical heat exchanger, which, in turn, reduces the power consumption of a heating, ventilation and air conditioning system (HVAC) that would include the cylindrical heat exchanger.

Abstract translation: 圆柱形热交换器通常由多个螺旋通道构成，该多个螺旋通道由多个同心圆形产生，直径逐渐增加，彼此重叠。 然而，每个通道通常包括在这种圆形层之间的波纹板，并且波纹板用作障碍物，从而当气流通过时减小空气流的压力。 本发明是一种圆柱形换热器，其具有由螺旋缠绕的矩形片形成的多个螺旋形通道，其中通过缠绕矩形片形成的重叠螺旋层由多个径向对准的分隔件隔开。 分隔器以及介于螺旋层之间的开放界面层保持螺旋之间的恒定间隙。 因此，制造具有螺旋而不是同心层的圆柱形换热器改进了制造这种装置的过程。 另外，用开放的界面层替换波纹板减少了通过圆柱形换热器的空气流的压降，这又降低了加热，通风和空调系统（HVAC）的功率消耗，其将包括 圆柱形换热器。

Abstract: Existing plate-type heat exchangers typically include plates that are constructed of metal or paper, which are only capable of transferring a limited amount of moisture, if any, from one side of the plate to the other side. The present invention is a plate-type heat exchanger wherein the plates are constructed of ionomer membranes, such as sulfonated or carboxylated polymer membranes, which are capable of transferring a significant amount of moisture from one side of the membrane to the other side. Incorporating such ionomer membranes into a plate-type heat exchanger provides the heat exchanger with the ability to transfer a large percentage of the available latent heat in one air stream to the other air streams. The ionomer membrane plates are, therefore, more efficient at transferring latent heat than plates constructed of metal or paper.
