  • Patent number: 7137580
    Abstract: A venturi receives incoming material through an inlet tube and subjects the material to pulverization. The material, as it undergoes pulverization, is further subject to moisture extraction and drying. An airflow generator, coupled to the venturi, generates a high speed airflow to pull the material through the venturi and into an inlet aperture in the airflow generator. The airflow generator directs the received pulverized material to an outlet where the material may be subsequently separated from the air. An acoustic emission sensor receives the resonant frequencies generated by material passing through the airflow generator. The resonant frequencies reflect a material flow rate that is adjusted to avoid an overload situation. An automatic balancer system couples to an axel rotating the airflow generator to provide balance, improve efficiency, and eliminate cavitation.

    Abstract: An apparatus and method for mincing a gel includes a gel mincing tube and a mesh material. The mesh material extends across the end of the tube. To subdivide a gel using the mincing apparatus, a gel is placed upon the mesh material in the mincing tube, the mincing tube, mesh material and the gel are spun in a centrifuge, forcing the gel through the mesh material so that the gel is subdivided into generally uniform smaller fragments. The mesh material may be secured to a tube in the form of a nesting tube. The nesting tube nests within the opening of a recovery vessel. The mesh material may be placed in series with a conditionally porous membrane in the nesting tube. Centrifuging the nesting tube and the recovery vessel subdivides gel material into fragments by forcing the gel through the mesh material.

    Abstract: A method of obtaining improved reproducibility of dissolution profiles of dosage forms containing pharmaceutically active particles includes steps of screening raw pharmaceutically active particles to obtain or isolate particles having a desired monomodal particle size distribution. The particles having a monomodal particle size distribution may be incorporated into a solid oral dosage form to provide a highly reproducible dissolution profile. Two or more collections or particles having different monomodal particle size distributions may be combined and incorporated into solid oral dosage forms to provide predictable dissolution profiles.

  • Publication number: 20040011902
    Abstract: The invention relates to recycling wornout tyres and other industrial and domestic wastes. According to a method for shredding wornout tyres a package of wornout tyres is formed as a number of closely compacted layers. The package is subjected to primary destruction in an armored chamber under conditions of free extension until the package outside layers are destroyed. The overall dimensions of the armored chamber in any cross-section thereof square with the chamber axis and passing through the package of the compacted tyres varies within the range of from 2 to 7 package diameters in such section. The compact package of tyres is formed from a few coaxial helical twists having an axial hole. According to the invention, a stress-strain state is established upon free extension of a rubber layer without its contacting with the walls of the armored chamber, whereby efficient destruction and disintegration of the rubber, metallic and textile cord of a tyre is attained.

  • Patent number: 6680110
    Abstract: The present invention relates to a method of reducing particle size by the use of a supercritical gas, such as carbon dioxide or a refrigerant. The material is swollen by the supercritical gas at a high pressure. After the material has been allowed to swell under a high pressure, the pressure is rapidly dropped. When the external pressure is rapidly dropped, the material explodes as the supercritical gas absorbed into the material rapidly expands outward.

  • Patent number: 6669122
    Abstract: Method of shaping solid, particulate materials, which comprises forming a raw slurry of the starting material, in a liquid which is a partial solvent of said material, and submitting the slurry to treatment by ultrasound generators to produce therein ultrasonic vibrations which shape and grind the starting, particulate material to produce a shaped slurry of ground and shaped particles. The shaped particles may be separated from their slurry by removing the partial solvent by decantation and/or filtration. The partial solvent may be a liquid in which the material to be shaped has a solubility comprised between 1 and 10, wherein the solubility is expressed as grams of material that are dissolved in 100 ml of the liquid at a temperature of 20° C. The partial solvent can be chosen from among acetone, methyl ethyl ketone, and mixtures of said solvents with one another or other solvents and/or a minor amount of water, and may also be an organic solvent.

  • Patent number: 6638757
    Abstract: A process is provided for the biological digestion of animal carcasses. First, the carcass is cut into smaller pieces with equipment that masticates, grinds or comminutes in the presence of water to create a solid-liquid mixture. The next steps include treating the solid-liquid mixture with a special blend or combination of bacteria that have been specifically cultured to digest the carcass; the mixture is subsequently aerated to form a stabilized biomass. The stabilized biomass is aerated in an open basin to further digest and liquefy the carcass, water, bacteria mixture. From the open basin, the primarily liquid waste stream is passed to a clarifying tank where the suspended solids are precipitated as sludge, thus clarifying the liquid. Sludge is removed from the clarifying chamber and the clarified liquid is either discharged or recirculated for further use in this novel process.

  • Publication number: 20030029944
    Abstract: Method and apparatus for assisting recovery of desired materials from ore are disclosed. Desired material liberation is assisted by applying high power microwave energy to the ore. Application of high power microwave energy causes materials within the ore to react with gaseous compounds in the air to form a plasma. The plasma is retained proximate the ore to facilitate heating of the ore to induce stress formation within the ore and/or mineral oxidation of ore materials. The additional heat, stresses, and fractures caused via application of the high power microwaves facilitate desired material liberation from the ore during subsequent material extraction processes.

  • Publication number: 20030026842
    Abstract: Hard, dense particles of a pharmaceutical agent, suitable for administration to a subject via a needleless syringe are described. The particles are prepared by a multi step process that entails forming particles of a first size where the particles are an admixture of a pharmaceutical agent and a macromolecular carrier and the admixture has a first glass transition temperature; admixing a plasticizer that lowers the first glass transition temperature of the admixture to a second glass transition temperature which is below the first glass transition temperature; maintaining the articles at a temperature above the second glass transition temperature for a time period adequate to cause the particles to shrink and/or collapse; removing the plasticizer from the particles to yield modified particles having an increased glass transition temperature; recovering the modified particles; and then storing the recovered particles.

  • Patent number: 6508421
    Abstract: The invention provides a method and installation for processing heterogeneous value bearing material by pressure comminution. The material is compressed in a bed of particles, at low pressures and at low bulk material densities, and preferably no more than is necessary to liberate the desired values, thereby to minimise the formation of fines. The compressive bed pressure applied to the material does not exceed 300 MPa, and the process is preferably operated in an open circuit mode. Surprisingly, these measures lead to enhanced liberation of values compared with conventional comminution techniques.
