  • Patent number: 8974593
    Abstract: Cement-SCM blends employ particle packing principles to increase particle packing density and reduce interstitial spacing between the cement and SCM particles. Particle packing reduces the amount of water required to obtain a cement paste having a desired flow, lowers the water-cementitious material ratio (w/cm), and increases early and long-term strengths. This may be accomplished by providing a hydraulic cement fraction having a narrow PSD and at least one SCM fraction having a mean particle size that differs from the mean particle size of the narrow PSD cement by a multiple of 3.0 or more to yield a cement-SCM blend having a particle packing density of at least 57.0%.

  • Patent number: 8794552
    Abstract: Apparatus for separating components of post-consumer carpet—pile, adhesive, and primary/secondary backings—may initially comprise spectrographic face fiber identification. Separating substantial portions of pile from backing comprises feeding carpeting into a rotating pinned drum, with separated pile U's dropping, while a residual composition, being primarily backing, travels with the drum, to be separated therefrom using vacuum pressure, with the composite backing being sent to a press. Vacuum pressure delivers the separated U's to a spinning perforated squirrel cage to remove dislodged pieces of adhesive, by vacuum pressure applied to an interior top portion of the cage to draw pieces therein. Rotating the perforated squirrel cage, which is sealed on the exterior using a belt, permits the U's to drop into a hopper. A mesh shaker box vibrates to separate any remaining backing from the pile U's. Hammers in a fibermill remove remaining adhesive attached to the separated pile U fiber.

  • Patent number: 8652405
    Abstract: To improve throughput of biomedical waste treatment, the present inventors devised an exemplary ozone-based system including a shredder, a roll-off treatment bin with ozone injectors, an ozone source, and a controller. The controller monitors electric current drawn by the shredder as shredded waste enters the ozone-enriched treatment bin. In response to current falling below a predetermined low level, indicating that a batch of waste has been shredded and loaded into the treatment bin, the controller starts a treatment timer. The timer measures elapsed ozone treatment or exposure time. If additional waste is added to the shredder and a subsequent low-current condition is detected, the controller restarts the treatment timer. Expiration of the timer indicates that the waste in the roll-off bin is sterilized and ready for transport to landfills. The exemplary system provides continuous waste processing and promises to boost throughput by 50% over some conventional ozone-based waste-treatment systems.

  • Patent number: 8485456
    Abstract: A method and apparatus for manufacturing a submicron polymer powder from solid polymer bodies or coarse particles, preferably of polytetrafluoroethylene powder, wherein powder is ground into fibrous particles in the first stage and is disintegrated into submicron particles by aerodynamic treatment in the second stage, where a gas-particle mixture is subject to the effect of centrifugal forces and suction forces acting in the direction opposite to the centrifugal forces, a pulsating sign-alternating temperature field generated by a pulsed supply of liquid nitrogen, turbulent forces of vortexes, and aerodynamic forces that cause alternating compression and expansion of the gas-particle mixture.

  • Patent number: 8453953
    Abstract: The invention provides low-cost, non-thermal methods to transform and beneficiate bulk materials, including low rank coals such as peat, lignite, brown coal, subbituminous coal, other carbonaceous solids or derived feedstock. High pressure compaction and comminution processes are linked to transform the solid materials by eliminating interstitial, capillary, pores, or other voids that are present in the materials and that may contain liquid, air or gases that are detrimental to the quality and performance of the bulk materials, thereby beneficiating the bulk products to provide premium feedstock for industrial or commercial uses, such as electric power generation, gasification, liquefaction, and carbon activation. The handling characteristics, dust mitigation aspects and combustion emissions of the products may also be improved.

  • Patent number: 8434705
    Abstract: This invention relates to a shredding device having a driving unit driving a rotor including shredding tools on its periphery which for comminuting a material such as waste material and/or industrial residues, interact with a least one counter knife assembly that is arranged in a stationary fashion with respect to the machine housing during the shredding operation. The shredding device is characterized in that the counter knife assembly includes at least two counter knife bars which run approximately parallel to each other and are arranged one above the other in the rotating direction of the rotor, the counter knife bars, for the compensation of wear at the shredding tools and/or at the counter knife assembly, being arranged for an adjustment radially to the rotor axis by a mutually different degree by means of an adjustment device. A process for operating a shredding device is also described.

  • Patent number: 8418943
    Abstract: A method for processing unseparated egg shells includes placing unseparated egg shells in a separation tank containing fluid, applying cavitation to the unseparated egg shells in the fluid to thereby separate the egg shell membranes from the egg shells, and recovering the egg shell membranes. An apparatus for processing unseparated egg shells includes a separation tank for holding a fluid, a recirculating loop operatively connected to the separation tank, and at least one submersible mixer in the recirculating loop to recirculate the fluid and egg shell membranes and egg shells within the fluid. The apparatus further includes a membrane collection conveyor for conveying egg shell membranes from the separation tank and a shell conveyor positioned beneath the separation tank for conveying egg shells away from the separation tank.

  • Patent number: 8420875
    Abstract: The conversion of waste plastics material to hydrocarbon fuel products, particularly transportation fuels. The waste plastics material can be obtained from any suitable source, such as a municipal solid waste facility and from agricultural and horticultural activity. The plastics material feed, which can contain from about 10 to about 50 wt. % dirt, is reduced to an effective size, then dried, if needed, to a moisture level of 2 wt. % and less, then screened to removed dirt, then densified into nuggets of at least about 10 lb/ft3, then pyrolyzed.

  • Publication number: 20130043334
    Abstract: A high inertia cylindrical mass element having one or more food chopping blades detachably affixed thereto is positioned within a transparent cylindrical tube containing food to be chopped. The tube containing the high inertia cylindrical mass element is dimensioned to permit the tube to be moved back-and forth much more than the mass element is moved therein due to the high inertia of the cylindrical mass upon the manually induced to-and-fro motion of the tube by the user that results in chopping of the food. In addition to creating the back-and forth movement of the tube, the user also twists the ends of the tube with her wrists while the tube is grasped which results in relative rotary displacement of the tube relative to the high inertia cylindrical mass carrying cutting blades that tends to chop the food more uniformly.

  • Publication number: 20130001336
    Abstract: A method for automated destringing and breaking down of baled biomass material using limited manual labor is disclosed. The method includes selecting and moving one bale of biomass material from a stack of bales to an automated destringing station where the string is removed from that bale. The bale is then lined up next in line with previously processed destrung bales and advanced along a continuous process line through a bale chopper that breaks the biomass material down into useful pieces for further processing at the facility. In a preferred embodiment an automated initial quality control evaluation step can be provided with a bale rejection system operated on detected non-conforming bales before they are destrung.
