Abstract: A portable water treatment system includes at least one sub-system to treat water including a flocculation system, a chlorination system, and a bio-sand filter system. The water treatment system may include multiple sub-systems for treating water that feed into one another. The sand filter system may include a mini bio-sand filter, a foam filter, or a pressed block filter. The flocculation system may include a tank bottom that urges settling particles toward a sump and a ladle that removes settled particles. A manual pump or siphon may be included in the water treatment system.

Abstract: A composite metal surface that looks metallic, but permits effective transmission of an electromagnetic field. The composite metal surface can be integrated into various electronic equipment, such as telephones, remote controls, battery doors, keyboards, mice, game controllers, cameras, laptops, inductive power supplies, and essentially any other electronic equipment. The composite metal surface can also be integrated into non-electrically conductive heat sinks, high permeability shielding, and polished metal non-electrically conductive surfaces.

Abstract: A wireless power supply and a portable heating device are provided. The wireless power supply includes an electromagnetic shield and the portable heating device includes a magnetic field source. Placement of the magnetic field source proximate the electromagnetic shield can create a local flux window in the electromagnetic shield. The transfer of electromagnetic flux through the local flux window energizes the portable heating device at various locations along the wireless power supply. The effectiveness of the electromagnetic shield is generally maintained away from the flux window, and the electromagnetic shield reduces stray flux that might otherwise damage nearby objects and/or reduce the efficiency of the wireless power supply.

Abstract: A flux concentrator and method for manufacturing a flux concentrator is provided. The method can include combining powdered soft magnetic material, a binder, a solvent, a internal lubricant; mixing the materials to create a mixture, evaporating the solvent from the mixture, molding the mixture to form a flux concentrator, and curing the flux concentrator. The flux concentrator may be laminated and broken into multiple pieces, which makes the flux concentrator more flexible. Breaking the flux concentrator does not significantly affect the magnetic properties. Since the permeability of the binder is very similar to that of air, adding tiny air gaps between the fractions is not significantly different than adding more binder.

Abstract: A water treatment system (“WTS”) includes a prefilter, a carbon block filter and a microbiological interception (“MI”) filter that operate in combination to treat a fluid stream, such as water. The WTS may include two prefilters, for example, both a multi-layer nonwoven prefilter and a pleated fabric prefilter. The MI filter may include carbon particles and a binder, and the carbon particles may have a mean particle diameter ranging from about 60 microns to about 80 microns and with a particle size distribution in which no more than about 10% by weight of the particles are larger than about 140 mesh and no more than about 10% by weight are smaller than about 500 mesh. In one embodiment, the water treatment system further includes a volumetric end-of-life filter monitor that monitors the life of the MI filter.

Abstract: An activated carbon filter that treats a gas stream having a varying relative humidity, the gas stream contaminated with at least one of formaldehyde, an acid gas and an alkaline gas. The filter includes a plurality of activated carbon granules mixed together in a carbon bed filter. A first portion of the granules supports both manganese dioxide and potassium hydroxide. A second portion of the granules supports both potassium iodide and potassium hydroxide. A third portion of the granules supports phosphoric acid. The different portions operate to catalyze the oxidation of formaldehyde and other contaminants at varying humidity. The potassium hydroxide optionally chemisorbs any carboxylic acid by-products of the formaldehyde. Also provided is a method to treat a gas stream with the filter.

Abstract: The present invention relates to a point-of-use water treatment system unit (10). The unit (10) includes a filter housing assembly (60) having a filter tank assembly (66) and a closure (64) which utilizes a handle (152) and cammed reciprocating lock blades (146, 150) to secure the closure (64) to the filter tank assembly (66). A UV tank assembly (300) includes a planar baffle plate (322) and a vaned baffle plate (324) to induce plug flow about a UV lamp assembly (280). The UV lamp assembly (280) is used which simultaneously electrically and sealingly mounts to UV tank assembly (300) and electrical cap assembly (290) using a bayonet mount. A bi-planar manifold assembly (40) is used to interconnect components of the WTS unit and to provide an envelope for accommodating a water pipe assembly (34). The bi-planar manifold assembly (40) enhances the compactness of the design of the WTS unit (10).

Abstract: A drain cleaning composition includes at least about 40% by weight of a free-flowing coated alkali metal hydroxide and about 5% to 20% by weight of mixture of a hypochlorite generator and a peroxide generator. The hypochlorite and peroxide generators react to release oxygen gas and hypochlorite ions, the hypochlorite generator being in stoichiometric excess over the peroxide generator to produce free hypochlorite ions for dissolving hair and other protein based clogs. The coating on the drain cleaning composition prevents the hydroxide from reacting with the other components of the mixture before the mixture is added to water.
