  • Patent number: 7954733
    Abstract: A method for processing unseparated egg shells is provided. The method includes placing the unseparated egg shells in a fluid tank containing a fluid mixture, applying cavitation to the fluid mixture to thereby assist in separating the egg shell membranes from the egg shells, and recovering the egg shell membranes. Preferably, the fluid mixture is recirculated to thereby provide for continuous processing of unseparated egg shells. The method may further include drying the egg shell membranes to produce dried egg shell membranes which may then be vacuum packaged for storage and/or transport. The dried egg shell membranes may then be subjected to an extraction process for extracting at least one type of polypeptide from the egg shell membranes. Collagen, hyaluronic acid, or amino acids of interest may be extracted from the egg shell membrane and purified for numerous uses.

    Abstract: A method is disclosed for reducing the mechanical strength of solid biomass material, in particular ligno-cellulosic biomass. The method comprises heating the solid biomass material to a temperature in the range of 105° C. to 200° C. The heat treatment, which is referred to as “toasting”, significantly reduces the mechanical energy required for reducing the particle size of the solid biomass material. The method is particularly suitable as a pretreatment step to a conversion reaction of the solid biomass material.

The systems/methods are particularly advantageous for fluidization of nanoparticle and/or nanopowder systems, where the generation and/or presence of static electricity is a significant fluidization issue. The systems and methods generally involve the addition of an alcohol or other solvent to a fluidization gas to be introduced to the fluidization chamber, e.g., by bubbling the fluidization gas through a volume of solvent/alcohol, to advantageously reduce the build up of electrostatic charge. Systems and methods for capturing in-situ images within a fluidized bed are also provided that involve reducing the electrostatic charges generated within the fluidized bed and introducing a particle vision and measurement (PVM) probe to the fluidized bed for image capture.

    Abstract: The present invention relates to a metal treatment composition including Tin (II) Chloride and processed montmorillonite clay. The addition of Tin (II) Chloride to the composition provides Tin for forming a ceramic-metal layer on the surfaces of the friction pair. Tin (II) Chloride provides Chlorine ions for forming Chloric films for protecting juvenile surfaces which form in the friction zone. The clay is heated and pulverized to produce a powder comprising both particles having crystalline layer structure and salts and oxides. The layered crystalline structure of the clay contains slip planes that transversely shift when tangential pressure from the friction pair is applied thereby lubricating the friction pair.

  • Patent number: 7658340
    Abstract: With the coupling of an external field and aeration (or a flow of another gas), nanoparticles can be smoothly and vigorously fluidized. A magnetic force and/or pre-treatment may be employed with the fluidizing gas and, when coupled with a fluidizing medium, provide excellent means for achieving homogenous nanofluidization. The magnetic force interacts with non-fluidizing magnetic particles and helps to break channels as well as provide enough energy to disrupt the strong interparticle forces, thereby establishing an advantageous agglomerate size distribution. Enhanced fluidization is reflected by improved performance-related attributes. The fluidized nanoparticles may be coated, surface-treated and/or surface-modified in the fluidized state. In addition, the fluidized nanoparticles may participate in a reaction, either as a reactant or a catalyst, while in the fluidized state.

A conglomerate of activated mixed crystals is then obtained. Said conglomerate has an increased aptitude for the formation of modified crystals when water is added. The duration of the effect of the impacting pressure fronts continues until the crystal lattice structure of the particles (30) is destroyed. A device for the disintegration and tribochemical activation of said materials is based on rotating disks whereon molded bodies with aerodynamical profiles are arranged, said molded bodies being continuously displaced in a transonic speed range and impacting pressure fronts being produced on the outflow surfaces thereof.

  • Patent number: 7448561
    Abstract: A combined process for the conversion of solid starting particles into solid intermediate particles and reducing the median diameter of the intermediate particles to obtain product particles. This process involves flowing a suspension of starting particles through a series of at least two conversion vessels, thereby converting at least part of the starting particles into intermediate particles, adding a supercritical fluid to one or more of the conversion vessels, thereby forming a supercritical suspension, and releasing pressure from the supercritical suspension, thereby expanding the suspension and converting the intermediate particles into product particles.

  • Patent number: 7449072
    Abstract: A method and apparatus for removing solid or semi-solid material from within a container, for example removing an energetic material from the casing of an explosive shell. The method is applicable to the demilitarization of aged or obsolete explosive ordnance, for example mortar rounds, and uses ultrasonic energy rather than heat like previous methods. An item to be demilitarized and cleaned is immersed in a fluid contained within a vessel. An ultrasonic probe or wand is inserted into the submerged item, in proximity with the material to be removed. The fluid is the medium for transmitting sonic energy from the probe to the material to fracture and mobilize the material. Mobilized particulates are expelled from the casing, and settle to the bottom of the fluid vessel for collection. At the conclusion of the process, the emptied container shell, now relatively clean, is retrieved from the vessel and salvaged as desired.

  • Patent number: 7429008
    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.

  • Patent number: 7264182
    Abstract: A method and device that comminutes particulate organic substances in suspensions of microorganisms in mediums such as wastewaters or sludges of biological sewage treatment plants, whereby the organic substances are subjected to inertial forces in an active chamber as a result of short-term acceleration, immediately followed by deceleration of a carrier medium flowing in a closed flow channel. To generate these inertial forces, the carrier medium is evaporated and subsequently condensed in the active chamber, whereby this change in the carrier medium's aggregate state is achieved by changing the flow speed. Because of the enormous increase of the liquid phase volume upon its transition into the vapor state, the flow speed of the medium concomitantly increases. As a result, extreme acceleration forces are exerted on the loading of the liquid phase, which immediately after condensation of the vapor into the liquid phase revert back into deceleration forces.

    Abstract: This is a method for working and processing different materials, mainly elastomers, in different manufacturing processes. Moving cutting tools act upon the material to create ultrasonic-frequency oscillations of the material in a working zone. The power of the drive units is set at no less than 100–300 kW. The revolution speed of the tool is set in the range of 3,000–12,000 rev/min. The quantity of cutting edges for the tool is selected according to the relation ?×n is less than 800, where ? is equal to the angular velocity of the tool and n is equal to the number of cutting edges of tool. The attach angles of the tool are set in the range of 85–95 degrees. Separate particles of material embedded to the cutting portion of the tool are removed using a fluid flow containing gas and/or liquid. The effect is an enhanced efficiency of method, increased disposition degree and uniformity of ready product structures.
