The wastewater treatment systems have a plurality of treatment modules between the inlet and the outlet, each for treating water with a selected process. Influent is directed to a covered anaerobic reactor, and then to an attached growth pretreatment filter that is at least intermittently exposed to atmospheric oxygen. Following the filter is a hydroponic reactor followed by a vertical-flow wetland. A second embodiment includes, following the filter, a tidal vertical-flow wetland and a pump for recycling water exiting the wetland upstream of the filter.

Disclosed is a process for making alkoxylates of organic compounds. The process requires a) providing an active hydrogen organic compound having 1 to 22 carbon atoms, and b) alkoxylating the organic compound with an alkylene oxide in the presence of a catalytically effective amount of a catalyst compound corresponding to either formula (I) or formula (II): B(.phi.).sub.3 (I) H.sup.+B(.phi.).sub.4.sup.- (II) wherein B is a boron atom and H is a hydrogen atom; .phi. is a phenyl moiety having substituents selected from the group consisting of 1 to 5 fluorine atoms, 1 to 5 CF.sub.3 moieties, 1 to 5 OCF.sub.3 or SCF.sub.3 moieties or OR; wherein C is a carbon atom, O is an oxygen atom, S is a sulfur atom and F is a fluorine atom; wherein R is a hydrogen atom or an alkyl or aryl group having from 1 to 22 carbon atoms. The process affords a product of very narrow molecular weight distribution with a low degree of both residual active hydrogen organic starting material and undesirable by-products.

A hot-working steel article, e.g., tool, comprising a material which comprises, in % by weight, 0.451 to 0.598 C, 0.11 to 0.29 Si, 0.11 to 0.39 Mn, 4.2 to 4.98 Cr, 2.81 to 3.29 Mo, 0.41 to 0.69 V, with the balance iron, contaminants and accompanying elements, as well as an alloy and a process for making said article.

A stable distillate fuel blend useful as a fuel or as a blending component of a fuel that is suitable for use in an internal combustion engine, said fuel blend prepared from at least one highly paraffinic distillate fuel component and at least one highly aromatic petroleum-derived distillate fuel component and a process for preparing same involving the blending of at least two components having antagonistic properties with respect to one another.

The invention relates to a composition which comprises a dispersion of micro spheres in a gel comprising an oily base and an organic polymeric gelling agent.

A fraction of diisocyanates of the diphenylmethane series containing at least 95 wt. % binuclear methylenediphenyl diisocyanate is obtained bya) reacting aniline and formaldehyde in the presence of an acid catalyst to produce diamines and polyamines of the diphenylmethane series containing binuclear methylenediphenyl diamine,b) phosgenating the diamines and polyamines produced in a), optionally in the presence of a solvent, to produce a crude diisocyanate and polyisocyanate, andc) separating a fraction containing at least 95 wt. % binuclear methylenediphenyl diisocyanate with a 4,4′-MDI content of over 60 wt. %, a 2,4′-MDI content of 4 to 35 wt. % and a 2,2′-MDI content of 0.01 to 10 wt. %, relative to the mass of the fraction, and a maximum of 20 ppm phenyl isocyanate and optionally a maximum of 50 ppm solvent from the crude diisocyanate and polyisocyanate produced in b) in a single distillation step with optional upstream and / or downstream separation of low-boiling components.

The invention relates to a method for manufacturing alkaline magnesium-rich pellet ore. The method comprises the steps of I pretreatment of recycled waste magnesia-calcium bricks, wherein a, primary breaking is carried out, and the waste magnesia-calcium bricks are broken into magnesia-calcium brick blocks; b, fine grinding is carried out, and the magnesia-calcium brick blocks are ground into magnesia-calcium brick powder; II batching, wherein iron concentrate powder and the magnesia-calcium brick powder are batched into batch mixtures, and 5.5-6.6 parts of the magnesia-calcium brick powder, 100 parts of the iron concentrate powder, 0.5-1 part of pulverized coal and 1.7 parts of bentonite are adopted according to the ratio; III pretreatment of the batch mixtures, wherein roll grinding is carried out on the batch mixtures; IV mixing, wherein the batch mixtures obtained through roll grinding are mixed; V pelletizing and screening, wherein mixed materials are pelletized and screened into qualified green pellets; VI drying, preheating and calcination, wherein the qualified green pellets are calcinated into pellet ore; VIII cooling, wherein the pellet ore is cooled to obtain the alkaline magnesium-rich pellet ore. The alkaline magnesium-rich pellet ore is produced through the waste magnesia-calcium bricks, the quaternary alkalinity of the pellet ore can be above 1.15%, and MgO is larger than or equal to 3.8%.

A sterilized food product containing starch, the starch having: (a) an amylose content of at least 60 wt. %; (b) a median particle size of between 1 and 15 &mgr; m, at least 90 wt. % of the starch particles having a particle diameter of less than 50 &mgr; m; and (c) a non-digestible starch content of less than 50 wt. %; and (d) a slowly digestible starch content of 15-75 wt. %. The product is obtained by heating and rapidly cooling the starch product and has a high slowly digestible starch content. It is suitable for use in the treatment of diabetes, obesitas, insulin resistance, or for postprandial glucose response.

An improved primary optics light projection system comprising a cone shaped reflector designed within specified mathematical parameters and a light source placed near the apex focal point cross sectional area of said reflector is disclosed for projecting a vortex of light rays with a precise shape and an even beam field containing a maximum number of light rays produced by a light source having a small or large diameter or cross section. A reflector near the base of the light source and perpendicular to the cone shaped reflector and one or more lens may be included to increase efficiency. The cone shaped reflector may be made in various cross sectional shapes providing means for using light sources with a square, rectangular, round, oval, or unconventional shape allowing the use of high efficiency light sources such as, but not limited to, light emitting diodes, often used in clusters of multiple LEDs.
