Abstract: The present invention relates to functionalized molecular sieves that are useful as shape-selective adsorbents and catalysts. The inventive molecular sieves have a crystalline framework and include micropores of substantially uniform size and shape formed therein. These micropores contain one or more accessible organic moieties that are linked to the crystalline framework by a carbon-silicon ond. Shape selectivity of the inventive molecular sieves may be modulated by varying the size and shape of the micropores (which is a function of the particular molecular sieve being synthesized) and the organic moiety incoporated therein.

Abstract: A method and apparatus for delivering a constant amount of dough per unit time is disclosed. Successive dough blocks (5) are transferred on a first conveyor (8) at times proportional to their weights. The predetermined theoretical traveling distances of the dough blocks and the actual traveling distances of the dough blocks on the first conveyor are compared to find the change of the volume or specific gravity of the dough due to fermentation. Based on the comparison the traveling speed of the first conveyor is changed to obtain a uniform amount of the dough product, and the gap between a second conveyor (11) and a stretching roller (12) may be adjusted to increase the rate at which the dough is produced.

Abstract: The present invention relates to an aqueous composition and improved process useful for cleaning and facilitate drying of various metallic and non-metallic surfaces or components. According to the invention the water-immiscible hydrocarbon or non-halogenated organic solvent cleaning step is followed by an aqueous displacement solution (ADS) which contains a surfactant component and a pH modifier component in sufficient amounts to substantially displace the hydrophobic organic solvent residue from on the surface of the substrate and prevent its redeposition. The improved process is an alternative for replacing the ozone depleting chlorofluorocarbons and Halogenated solvents (ODS) or other volatile organic solvents (VOC) being commonly used in cleaning variety of industrially manufactured metallic and non-metallic components.

Abstract: A simple, rapid, efficient and inexpensive process for on-site recycling of wastewater with minimal odor wherein the solid wastes generated by the water treatment process are dewatering on-site by solar energy to water content levels below those required for disposal. All operations, including solar dewatering, are accomplished in a compact unit which may be mobile. The solar dewatering unit includes a drying pan over which a solar collector window arrangement is disposed.In the process, wastewater, a water purifying composition and an oxidizing agent are additively mixed together in a first reactor settling tank and the resulting composition is neutralized to a pH of between 7.5-9.4. The added water purifying composition is then allowed to precipitate wherein it binds to and precipitates heavy metals as well as other impurities. The precipitated purifying composition forms a non-hazardous sludge at the bottom of the tank.
