Abstract: The present invention relates to a vehicular air cleaner. A DOR (Direct Ozone Reduction) system for suppressing deterioration of a purifying function of an ozone purifying material is provided. Active oxygen is produced by an ozone purifying function of activated carbon. The probability that the active oxygen contacts with a fin of a radiator on a rear surface side is higher than that on a front surface side of the radiator. Accordingly, the activated carbon on the rear surface side of the radiator is easily oxidized as compared with the activated carbon on the front surface side. Therefore, in the fin, a coating amount of the activated carbon on the front surface side of the radiator is adjusted to be larger than a coating amount of the activated carbon on the rear surface side. Thus, the probability that the active oxygen contacts with the activated carbon can be reduced.

Abstract: Conventional tannic acid and polyphenol anti-allergen agents are known as anti-allergen agents capable of deactivating allergens such as mites and pollen, but these agents have inferior heat resistance and pose problems with coloration, discoloration and elution.

Abstract: The invention is directed towards methods and compositions for treating piles of low-rank coal to inhibit its spontaneous combustion. The method involves applying to the low-rank coal a composition containing VAE and crude glycerin. The composition prevents water from evaporating out of the low-rank coal. This prevents the formation within the low-rank coal of hollow openings which are a huge factor in causing its spontaneous combustion. The composition has better performance than its ingredients do alone. In fact it is so effective that certain cumbersome low-rank coal-handling methods, such as FIFO recordkeeping and inventorying, not using pinch points, or only using elbow-free equipment can be disregarded when the composition is used.

The combination of the SDA and PAM has a synergistic effect so that the resulting composition yields unexpected results and is a more effective treatment than either SDA or the PAM alone.

Abstract: The invention is directed towards methods and compositions for treating piles of particulate materials to inhibit and prevent the loss of valuable fuel or mineral dust from being released from storage piles or open containers. The method involves applying to the pile a binder coating containing VAE and crude glycerin. The binder coating cures and hardens slowly so it is able to remain flexible while the pile or payload is still settling, jostling, being bumped, and otherwise moving around. This coating is especially effective for coal piles and also for piles within and for being moved by open topped railroad cars. The coating's flexibility prevents the coating from becoming brittle and shattering. The coating has better performance than its ingredients do alone. The coating is effective both when it is flexible and after it cures. As a result the invention can both prevent unwanted dust pollution as well as save its users money by avoiding loss of blown away material.

Abstract: Modifications to the extracellular polymeric substance, predominantly extracellular polysaccharide, of a biopolymer produced by Rhizobium tropici ATCC 49672 yield a stable dry salt transported more easily than a fluid or gel and more stable than either. The salt may be re-constituted with water on-site.

Based on comparison with dextran standards, an embodiment demonstrated a molecular weight over 511,000 D. Embodiments include a day salt that is precipitated from solution and in use is re-hydrated back to original form. When added to a sandy soil at 0.1% by dry weight, an embodiment decreased the hydraulic conductivity by three orders of magnitude.

Abstract: A fixing liquid for properly and economically suppressing or preventing dispersion of dust (asbestos dust) generated through weathering or demolition of a sprayed-on material containing asbestos is prepared by homogeneously incorporating a surfactant and a thickener (e.g., CMC) into a solution of a polysaccharide (e.g., gum arabic). When an appropriate amount of the fixing liquid is sprayed onto a sprayed-on material containing asbestos, dust due to weathering of the sprayed-on material is wetted and retained, and dispersion of dust generated during demolition of the material is suppressed or prevented. Even after drying of the fixing liquid, the viscosity of the liquid is restored by re-wetting with water, and dispersion of dust generated during demolition of the thus-treated material is suppressed or prevented. Since the thickener has an increased volume in the presence of water, the thus-treated material is readily removed.

Abstract: The present invention relates to a dust suppressant composition comprising a aqueous solution of polyvinyl alcohol, acrylic-based latex, glycerin, silicone based surfactant and a polysiloxane-based wetting agent. Preferably, the composition comprises from about 10 to about 46% of polyvinyl alcohol, from about 20 to about 60% of an acrylic-based latex, from about 0.6 to about 7.0% of glycerin, from about 0.1 to about 1.5% of silicone-based surfactant and from about 0.001 to about 0.5% of polysiloxane-based wetting agent.

The latter two properties ensure that there is less breakage of the polymer film during continuous use or application (e.g.

This allows the composition to continue to deodorize the ostomy bag headspace even after waste material begins to fill the bag.
