Abstract: A fluid aerator (1) comprising a fluid vessel (2) and a pipe (4) extending from the interior of the fluid vessel (2) to the exterior. The pipe (4) has inlet means for permitting liquid to flow into the pipe (4) from the vessel (2) and is closed at its lowermost end but has one or more outlet holes (8) arranged in the wall of the pipe where the fluid exists from the pipe (4). The pipe (4) is movable relative to the vessel (2) between a first position in which the outlet holes (8) are distant from the vessel and a second position in which the outlet holes (8) are closer to the vessel. By means of the movable fluid supply pipe (4) the same fluid aerator can be used both in relation to delivering aerated fluid into a large bottle and to delivering smaller amounts of aerated fluid to a smaller container, such as a wine glass.

Abstract: A self-regenerating bio-gas treatment system that uses the bio-gas instead of atmospheric are as media transport between adsorber and desorber tanks. Each tank includes at least four horizontally stacked and evenly spaced apart, perforated trays each capable being filled with fluidized carbon which migrates downward in the adsorber tank to remove contaminants from the bio-gas. With the bio-gas function as its media transport, the carbon media continuously moves downward over the perforated trays and eventually collected in the bottom of the adsorber tank. The spent carbon is then delivered to the desorber tank. The desorber tank is filled with an inert gas produced by an inert gas generator which causes the carbon media to be regenerated. The inert gas strips the carbon media of contaminates and is then delivered to a ground flare. The carbon media is returned to the adsorber tank and re-used to treat bio-gas.

Abstract: Hydrogen sulfide is removed from a hydrogen rich gas stream using adsorbents having a low loss of carbon dioxide adsorption capacity upon sulfur loading including high purity silica gels, titania or highly cross-linked, non-chemically reactive resins. The adsorbents may be used to adsorb both carbon dioxide and hydrogen sulfide, or may be used as a guard bed upstream of a separate carbon dioxide adsorbent.

Abstract: Prior to adding detergent or chelant, the conductivity of water in a washing chamber is measured. The maximum concentration of hard water ions that could correspond to the measured conductivity is determined, i.e., it is assumed that all of the conductivity is from calcium and/or magnesium ions in the water even though other ions may in fact be contributing to the measured conductivity. Enough chelating agent is added to the chamber to sequester this maximum concentration of hard water ions and the conductivity is measured again. Using the two conductivity measurements, the actual concentration of hard water ions is determined. A chelant factor based on the actual concentration of hard water ions is then used to determine the amount of chelant to be added for subsequent wash cycles to sequester all of the hard water ions.

Abstract: The present invention provides exterior building products, such as roofing and siding, shake, shingles, siding, sheathing, panels, planks, vertical siding, soffit panels, fencing, decking, fascia, corner posts, column corners and trim boards in which a plurality of cementitious layers are provided with an improved interlaminar bond by employing a resinous bond promoter, a rheological agent, mechanical means to distribute fibers in a direction which is perpendicular to the machine direction so as to bridge between layers in the product, or a combination thereof. These techniques help to increase interlaminar bond strength to improve the mechanical properties of the product. When certain resinous bond promoters are used, the additional benefits of water absorption resistance and pigmentation throughout the product can be provided with minimal expense. Improvements in interlaminar bond strength of about 10 46% were observed with a percent elongation improvement of about 7%.

Abstract: Methods for rapid sensing of dissolved toxic heavy metals use a hybrid inorganic material (“HIM”), which is synthesized from hydrated iron oxide (“HFO”) and calcium magnesium silicate. HIM thus synthesized is used in sensing dissolved toxic heavy metals. Water containing toxic heavy metals (e.g., lead, copper, zinc, nickel, etc.) is passed through a sorbent bed of HIM, whereupon it shows a sharp drop in pH after a certain length of time. The presence of HFO and calcium magnesium silicates in HIM synergistically provide a precipitous drop in pH, which is characteristic of the concentration and type of toxic heavy metal. Therefore, observing a change in pH indicates the presence and identity of heavy metal ions in a test water sample.
