  • Patent number: 9249305
    Abstract: This invention is based upon the discovery that activated carbon can be used to sequester polycyclic aromatic hydrocarbons that may be present in asphalt and creosote compositions. The treatment of asphalt and creosote compositions with activated carbon accordingly reduces the level of free polycyclic aromatic hydrocarbons in such compositions by sequestering them therein or removing them from the composition. After being sequestered the polycyclic aromatic hydrocarbons remain trapped in the asphalt or creosote composition, and are not available to the environment during normal processing into useful industrial products. This sequestration reduces the risk of exposing humans and the environment to the polycyclic aromatic hydrocarbons which would otherwise be free to migrate from the asphalt or creosote product during manufacturing and the service life of the product.

    Abstract: A process and a device for dry separation of a conglomerate of metal scrap of non-magnetic particles from magnetic ones. Dry separation equipment for metal scrap which have a sequence of magnets placed in line, the poles of which are north-pole to south-pole are unable to meet this requirement. This insufficiency is due to the fact that the conglomerate of metal scrap is not sufficiently shook. This procedure does mean that at the end of transportation there is still non-magnetic material and other stuff fixed to the magnetic material. Intensive motion necessary is achieved by this invention by locating magnets adjacent to one another with equal poles, north-pole to north-pole and south-pole to south-pole and so on.

  • Publication number: 20130341249
    Abstract: Identification of a material composition. The material composition is configured with a color additive that is embedded or otherwise not visible. The color additive identifies the specific material composition. A discrete section or sub-section of the material is deformed such that the embedded color additive is made visible in the optical spectrum, after which the discrete section or sub-section may be sorted for recycling.

  • Patent number: 8496750
    Abstract: A method for reducing the particle size of a pozzolanic material includes providing a pozzolanic material having an initial particle size and heating the pozzolanic material to cause a portion of the particles to at least partially fracture. Fracturing the particles creates a plurality of fissures that define sub-particles within the particles. The method also includes processing the fractured pozzolanic material to separate the sub-particles, thereby yielding the pozzolanic material having reduced particles.

  • Patent number: 8459463
    Abstract: The invention generally relates to a novel method of sorting seed by providing a first seed population with a fluorescent indicator and a second seed population visually identical to the first seed population under standard operating conditions. The seed populations are combined to provide a combined seed population. A lamp having an output corresponding to the activation wavelength of the fluorescent indicator and a color sorting system are paired to count or separate the seed populations, as desired.

  • Patent number: 8439201
    Abstract: The invention provides methods and systems for separating particles that exhibit different Raman characteristics. The method can include introducing nanoparticles, on which Raman-active molecules are adsorbed, into a photopolymerizable resin and exposing to excite Raman active vibrational modes of the molecules to generate Raman-shifted radiation suitable for polymerizing the resin such that the Raman-shifted radiation causes selective polymerization of a resin surrounding nanoparticles if the nanoparticles provide a Raman enhancement factor greater than a threshold. In addition, methods for electrically isolating nanoparticles, or selectively removing one type of nanoparticles from collections, are disclosed. These methods rely on generation of blue-shifted anti-Stokes photons to selectively expose portions of a photoresist covering the nanoparticles to those photons. Such exposure can cause a change in the exposed portions (e.g.

  • Patent number: 8434623
    Abstract: The present invention relates to a process for separating at least one first material from a mixture comprising this at least one first material and at least one second material, which comprises the following steps: (A) contacting of the mixture comprising the at least one first material and at least one second material with at least one selective hydrophobicizing agent in the presence of a suspension medium so that an adduct is formed from the at least one hydrophobicizing agent and the at least one first material but not with the at least one second material, (B) contacting of the adduct from step (A) with at least one magnetic particle which is functionalized on the surface with at least one polymeric compound having a transition temperature LCST (lower critical solution temperature) at a temperature at which the polymeric compound has hydrophobic character so that the adduct from step (A) and the at least one functionalized magnetic particle agglomerate, (C) if appropriate addition of further suspensio

  • Patent number: 8418855
    Abstract: A method and apparatus for separating solid particles of different densities, using a magnetic process fluid. The solid particles are thoroughly mixed in a small partial flow of the process fluid. The small turbulent partial flow is added to a large laminar partial flow of the process fluid, after which the obtained mixture of the respective partial process fluids is conducted over, under, or through the middle of two magnet configurations, wherein the particles are separated into lighter particles at the top of the laminar process fluid and heavier particles at the bottom of the laminar process fluid, each of which are subsequently removed with the aid of a splitter. After that furthermore the particles of low density and the particles of high density are separated from the respective process streams, dried and stored. Finally, the process fluid from which the particles have been removed is returned to the original starting process stream.
