Abstract: The present invention disclose a sulfur oxide trap that may be used to improve efficiency of a nitrogen oxide trap. Sulfur oxide has a deleterious effect on the performance of nitrogen oxide traps. The sulfur oxide trap of the present invention, comprises a monolithic substrate which is over-coated with an aluminum oxide layer and a mixed oxide layer of calcium oxide and magnesium oxide. In another embodiment of the invention, the sulfur oxide trap is integrated with a nitrogen oxide trap by coating the catalyst contained within a nitrogen oxide trap with a mixed oxide layer of calcium oxide and magnesium oxide. In each embodiment of the invention, the sulfur oxide trap can be regenerated by heating at elevated temperature for a short time period.

The integrated lean NOx trap includes a lean NOx trap containing a composite metal oxide mixture consisting essentially of about 80-100 wt % stoichiometric spinel MgAl2O4 and between about 0-20 wt % of CeO2 or CeO2—ZrO2. A method for removing NOx and SOx impurities from exhaust gases using the integrated lean NOx trap is also described.

A plurality of columnar pins are spaced apart one from the other in a non-uniform manner and affixed to the top surface of the spreader plate substantially perpendicular thereto. A highly porous heat conducting reticulated foam block substantially fills a space defined by said spaced apart columnar pins.

Abstract: A thermosiphon for cooling an electronic device having a mean width of dimension “b” comprises a boilerplate having a top surface and including a plurality of pyramid shaped fins projecting upwardly from the top surface. The boilerplate also has a bottom surface for receiving the electronic device to be cooled. A plurality of spaced apart condenser tubes is mounted above the boilerplate such that the boilerplate and the condenser tubes define a vapor chamber therebetween for receiving a working fluid therein. A plurality of convoluted fins extends between each adjacent pair of condenser tubes.

Abstract: The present invention provides a composition and method for storing and reducing NOx for lean burn internal combustion engines. The present invention uses composite metal oxides, in spinel structure, in conjunction with a typical LNT formulation to form an integrated LNT. The composite metal oxides in spinel structure act primarily as a SOx trapping element and also a secondarily NOx trapping element within the integrated LNT. In this integrated LNT, the sulfur is trapped and released in a way that does not allow the sulfur to go to the primary NOx trapping element, i.e. the alkali or alkali earth metal oxides, to poison the integrated LNT; thereby, leaving more reactive sites for the NOx trapping and conversion.

Abstract: A dual regimen acne treatment package includes an outer container, and disposed within the outer container first and second inner containers which are separate from each other. Each of the inner containers has an exposed dispensing means, the first inner container containing a solubilized salicylic acid acne treatment composition, and the second inner container containing a solubilized benzoyl peroxide acne treatment composition.

Abstract: The invention is a method of treating exhaust gases generated by an internal combustion engine using a NOx trap in the exhaust flow system. The method comprises locating a nitrogen oxide trap in the exhaust gas passage and cycling the air/fuel ratio of the exhaust gases entering the trap between lean and rich, such that the trap absorbs nitrogen oxides during the lean cycle and desorbs the nitrogen oxides when the concentration of the oxygen in the exhaust flow is lowered as during a rich cycle. The trap comprises: (a) a porous support material comprising mostly &ggr;-alumina; (b) a sulfur-suppressing metal selected from the group consisting of cesium, zinc and a combination of cesium and zinc; (c) a precious metal; and (d) a NOx sorption metal such as barium, the metals being deposited in the support material, the amount of the metals being individually dependent on the weight of the support material.

Abstract: An evaporator (10) with opposed pairs of generally vertically oriented flow tube surfaces (14) has corrugated air fins in which the tube surface spacing c, the interior radius r of a crest (20) joining adjacent pairs of fin walls (18), the fin pitch p separating adjacent crests (20), and the length l of louvers (22) cut out of the fin walls (18) bear the following relationship: 0≦r/c≦0.057, 0.89≦l/c≦1.01, and 0.29≦p/c≦0.43. This has been found to substantially improve condensate drainage, while not significantly penalizing heat transfer or air side pressure drop.

Abstract: An improved dehumidification system for automotive use includes a rotating, wheel like heat exchanger with axially open cells that carry a water adsorbing material. Opposed ambient air and heated air flows, covering opposite halves of the wheel, continually adsorb water on one side and are recharged on the other side. Alternating radially closed cells between the axially open cells carry no desiccant material, but receive a cross cooling flow, on the water adsorbing side of the wheel only, to remove the heat released during the water adsorption process. The desiccant recharging process on the other side of the wheel is not disturbed by the cross cooling flow.
