    Abstract: A separator for a crop harvester configured to harvest sugarcane. The separator includes a frame having: i) an inlet configured to receive cut sugarcane, wherein the cut sugarcane includes cut stalk and crop residue, ii) a cut stalk outlet configured to discharge the cut stalk from the frame; and iii) a crop residue outlet. An extractor is operatively connected to the crop residue outlet. The extractor includes a tapered nozzle disposed adjacently to the crop residue outlet and a fan disposed adjacently to the tapered nozzle, wherein the tapered nozzle is configured to provide a pressure differential between the crop residue outlet and the fan in response to air flow provide by the fan. The tapered nozzle, in one embodiment, is a truncated cone having a smaller end disposed adjacently to a flow of cut crop, wherein the fan draws air through the truncated cone to separate the crop residue from the cut stalk.

  • Patent number: 8357232
    Abstract: The present invention relates to a system and method for the separation of gaseous components from gaseous mixtures in order to control emissions and treatment of the gaseous components. In one embodiment, the system makes use of a fan or gas moving device to first impose centrifugal forces on gas streams as the gas moves from the center of the fan toward the periphery of the fan housing. Heavier gases are forced to the outer regions of the fan housing while lighter gases remain closer to the fan axis. The heavier gases and lighter gases exiting the fan housing flow into a duct at different flow rates, and the heavier gases are diverted from the larger volume gas streams and then processed.

  • Patent number: 8216330
    Abstract: A powered air cleaning system has a flow path extending through the system from an inlet to an outlet. A motor-driven fan is located along the flow path to draw particulate debris laden air into the inlet and rotate it about an axis to form a rotating flow that stratifies the debris laden air with the heaviest particles in the outermost orbits of the rotating flow. An ejector port ejects particulate debris laden air from the stratified rotating flow in the system. At least one de-swirl component located within the rotating flow aerodynamically redirects clean air from the innermost orbits of the stratified rotating flow toward the outlet to provide a positive airflow pressure out of the outlet. The system has a variable speed fan motor and an integrated controller for adjusting the speed of the motor and thereby the flow rate of clean air through the outlet of the system. The controller receives a signal that is a function of airflow requirements of a device supplied with clean air by the system.

  • Patent number: 8182565
    Abstract: A compressor incorporated with an oil separator having a separation chamber and communication holes. The separation chamber is placed adjacent to a discharge chamber, has a space formed in the entire inside of the separation chamber, separates oil-containing gas, which is introduced into the separation chamber, into gas and oil by centrifugal separation, allows the separated oil to drop downward, and upwardly extracts the separated gas. The communication holes interconnect the discharge chamber and the separation chamber and introduce the oil-containing gas, coming from the discharge chamber, into the separation chamber. The communication holes are arranged in the separation chamber, in a direction extending from a gas release side to an oil drop side. The structure of an oil separation section is simplified to improve productivity and reduce cost, and a high degree of design freedom of the position of a discharge port is obtained.

  • Patent number: 8147581
    Abstract: A separation housing houses a rotor with multiple suspension chambers. Each chamber has a radially extending web portion between two rotating discs. An orifice is provided through the radially extending web portion. Another web portion urges gas radially out of the rotor. Passages through the rotating disks permit entry of gas and solid particle mixtures into the suspension chambers at high speed traveling toward each other in a suspension adjacent to the orifice. The web portion that urges gas out of the chamber pulls gas away from the suspension zone. Gas moving through the aperture and into a clean gas chamber pulls gas in the opposite direction. The result is gas in the suspension zone being fixed relative to the rotor or changing direction. Centrifugal force moves solid particles radially out of the chamber.

  • Patent number: 8128731
    Abstract: A method for separating and enriching isotopes in an efficient and low-cost manner from a condensation-system (liquid or/and solid) material including two or more different isotopes by taking advantage of the sedimentation of atoms through an acceleration field by ultra-high speed rotation. The condensation-system material is placed in a sedimentation tank which is then housed in a supercentrifuge. The supercentrifuge in its rotor is rotation driven by an ultra-high speed rotation power source, and an acceleration field of energy of 100000 G to 1500000 G, i.e., about 100 to 800 m/s in terms of peripheral velocity, is applied to the above condensed (liquid or/and solid) material under such a temperature that is specified by an isotope material to be enriched. In this case, a difference in centrifugal force applied is provided between the isotopes in the condensed (liquid or/and solid) material comprising the at least two isotopes.
