  • Patent number: 8236185
    Abstract: Toxic substances such as heavy metals are extracted from a medium using a sorbent composition. The sorbent composition is derived by sulfidation of red mud, which contains hydrated ferric oxides derived from the Bayer processing of bauxite ores. Exemplary sulfidizing compounds are H2S, Na2S, K2S, (NH4)2S, and CaSx. The sulfur content typically is from about 0.2 to about 10% above the residual sulfur in the red mud. Sulfidized red mud is an improved sorbent compared to red mud for most of the heavy metals tested (Hg, Cr, Pb, Cu, Zn, Cd, Se, Th, and U). Unlike red mud, sulfidized red mud does not leach naturally contained metals. Sulfidized red mud also prevents leaching of metals when mixed with red mud. Mixtures of sulfidized red mud and red mud are more effective for sorbing other ions, such as As, Co, Mn, and Sr, than sulfidized red mud alone.

  • Patent number: 8080172
    Abstract: A method and composition for controlling an exothermic reaction between a powerful oxidizing agent such as the permanganate salts, and reducing agents such as polyhydroxy organic compounds, comprises non-charged, relatively hydrophobic pigments which can be slurried at relatively high solids. The pigment may be calcium carbonate, diatomaceous earth (diatomite), talc, or blends thereof. The pigments are not flocculated in permanganate slurries and can be dispersed at high solids contents. The dispersions can be spray dried or pelletized with controllable moisture contents from about 0.1 to 10%. The resulting composition yields effective control of the exothermic reaction with more uniform and reproducible results.

  • Patent number: 7194417
    Abstract: An automated method and system for identifying date-sensitive entries in a database wherein an obligation must be satisfied relative to the entry according to instructions provided by the beneficiary of the obligation. The method and system of the invention can be practiced from a location remote from the database and are particularly useful in a number of situations and particularly those wherein unticketed reservations are maintained in a storage medium for a time prior to issuance of a ticket to “firm up” the reservation to a ticketed status. The present system and methodology finds particular utility enforcing ticketing time limit rules on travel agency or other reservation and ticket issuers involved in the reserving and ticketing of airline bookings and the like and results in the reduction of no-shows and overbooking while increasing onboard load factors on sold-out flights in particular.

  • Patent number: 7014341
    Abstract: Functional yet decorative luminaires intended to create distinctive environments within specific areas of a space in which one or more luminaires are used, the luminaires of the invention visually tie to architectural elements of the space by providing a customizable glow of color surrounding a typically white light that acts to illuminate the space functionally. A downlighting luminaire configured according to the invention as one example is typically configured to utilize two separate reflectors, usually reflectors having concave reflective surfaces and being mounted concentrically within a housing, an inner reflector directing light centrally through an aperture of the luminaire with the light so directed typically being white light useful for illumination intended to facilitate usual activities within the space.

  • Patent number: 6974235
    Abstract: Prismatic structures having at least certain conventionally linear surfaces thereof configured in a non-linear fashion to control the direction of light exiting said structures, the invention functions to reduce light losses in a luminaire or the like while facilitating the emanation of light from the luminaire at an acceptable viewing angle and with a reduction in glare. Prisms, particularly splitter prisms, configured according to the invention are formed with at least portions of conventionally linear surfaces as arcuate, curvilinear or generally curving segmented surfaces so as to direct light out of the luminaire for useful illumination rather than in a wasteful direction back into the luminaire. Prisms configured according to several embodiments of the invention function to increase light efficiencies either upwardly or downwardly depending on illumination requirements.

  • Patent number: 6971218
    Abstract: Apparatus for banding a bundle of articles covered by a wrapping, such as tableware wrapped by a napkin, a manually wrapped bundle having at least one of said articles covered by said wrapping and being fed by a user of the apparatus into contact with a pre-cut elongated band having a cohesive material coated on at least certain surfaces of the band. The apparatus cuts the band to a desired length and positions the pre-cut band in surmounting relation to a pair of counter-rotating rollers, the rollers biasing the band about the bundle as the bundle passes between the rollers. On passage of the bundle between the rollers, cohesive material-coated ends of the band are brought together to adhere said ends together and to tightly band the wrapped articles together in essentially a single operational step.

  • Patent number: 6971772
    Abstract: Luminaire optical assemblies intended for pole-mounted and similar applications and capable of effective I.E.S. cutoff performance while exhibiting desirable light distributions even with vertically oriented lamping, the invention contemplates in primary embodiments light-transmissive reflector/refractor combinations typically formed of glass, acrylics and the like, uplight shielding and reflector assemblies of a variety of configurations being disposed within the reflector/refractor combinations to produce desired cutoff characteristics while preserving daytime appearance during nocturnal operation. In certain embodiments of the invention, uplight is controlled by the several variations of the uplight shielding and reflector assemblies to cause light-transmissive portions of the reflector/refractor combinations to subtly glow and thus produce a desired appearance while also producing cutoff characteristics necessary to reduce urban sky glow and glare.
