  • Patent number: 11484852
    Abstract: Planetary gear mechanisms require internal toothed gears in housings. A drive rotor and driven rotors are accommodated in a mixing space in a housing, and chemical inflow paths to the mixing space are formed in an upper portion of the housing. A mixture outflow path is formed in a lower portion of the housing. The mixing space is formed to allow the drive rotor and the driven rotors to rotate and to regulate the positions of the drive rotor and the driven rotors. Meshing the drive rotor with the driven rotors allows the driven rotors to rotate opposite to the rotating direction of the drive rotor accompanying the rotation of the drive rotor while the lower ends of the driven rotors are located above a bottom portion of the mixing space and the upper ends of the driven rotors are located below the lower surface of the lid body.

    Abstract: Sludge can be treated by placing it in a carrier sized for bulk shipment of sludge by road or by rail. An antipathogenic substance such as lime is mixed into the sludge located in the carrier in order to treat pathogens in the sludge. At least one mixer adapted for mixing sludge throughout the carrier is employed. A dispenser such as a conduit or a loader bucket can dispense the antipathogenic substance so that the mixer can mix the substance with the sludge. The sludge is transported in the carrier either before or after the mixing with the antipathogenic substance. The mixture of sludge and antipathogenic substance is allowed to remain in the carrier long enough to treat pathogens with the substance before unloading the sludge from the carrier at a destination established for utilization, storage, transfer or disposal of the sludge.

  • Publication number: 20090268547
    Abstract: Superfine powder particles (70-400 mesh, mean average) are wetted in a processing unit that disperses the powder by impact with an impeller before substantial contact with a solvent, such as water. The impeller is provided with posts that extend the dispersion zone above the impeller to capture and disperse any powder that may accumulate on the top of the impeller. The impeller is driven by a variable speed motor to adjust the rotational speed of the impeller to increase the efficiency of wetting. Processing may be adapted to wetting of other superfine materials, such as clays.

The system includes a first and a second container of solution, a hand-held homogenizer having a homogenizing assembly and an applicator assembly configured to fluidly communicate the first and second containers with the homogenizing assembly. The solution from each container is mixed by the homogenizing assembly when the solution is dispensed from the containers. The applicator assembly may be integrally formed with the homogenizer and may be configured to include an outlet for dispensing the homogenized solution. The outlet may form an applicator tip or a connection for releasably securing a hose or tube. The homogenizing assembly may be integrally formed with the applicator and may include rotors and stators.

  • Patent number: 7441942
    Abstract: The present disclosure is generally directed to systems and methods for applying liquid feed additives to a feed composition. In one embodiment, the system has a spray housing defining a spray chamber located adjacent a mix housing carrying a material composition. The mix housing defines a mix chamber, which contains an actuating device, such as an auger, that moves the material stream through the mix chamber. The mix chamber and spray chamber are in fluid communication. A spray nozzle is coupled to the spray housing and in fluid communication with an air source and liquid additive tank. The spray nozzle sprays a fog of air and liquid additive through the spray chamber and into the mix chamber, which gets deposited on the passing feed stream.

  • Patent number: 7367710
    Abstract: According to the present invention, an anti-reflective film formed under a resist film is removed in a photolithography process of a wafer without affecting the resist film. According to the present invention, in a photolithography process of a substrate, an anti-reflective film having solubility in the developing solution is formed and thereafter a resist film is formed. In development treatment after exposure processing, a developing solution is supplied to the substrate to develop the resist film. At an instant when the development of the resist film is finished, a second developing solution lower in concentration than the developing solution is supplied to the substrate. Only the anti-reflective film is dissolved and removed by the supply of the second developing solution. The developing solution is supplied to the substrate by a supply nozzle having a stirrer.
