  • Publication number: 20130150265
    Abstract: The invention offers the ability to rapidly synthesize multiple chemical compounds, particularly polymers of varying sequences, in parallel on the surfaces of carrier beads. Tinvention involves attaching up-converting phosphors (UCP's) to beads to create up-converting phosphor-loaded beads (UCP-loaded beads) with unique spectral characteristics. Using a dynamic sorting architecture each bead is cataloged based on its spectral characteristics, assigned a compound or polymer to be synthesized, and subjected to multiple rounds of sorting by a flow cytometer, wherein each round sorts the bead to an appropriate bin for a selected chemical reaction, such as the attachment of a monomeric subunit of the polymer sequence.

  • Patent number: 8101310
    Abstract: An electrochemical cell is provided which has a liquid anode. Preferably the liquid anode comprises molten salt and a fuel, which preferably has a significant elemental carbon content. The supply of fuel is preferably continuously replenished in the anode. Where the fuel contains or pyrolizes to elemental carbon, the reaction C+2O2??CO2+4e? may occur at the anode. The electrochemical cell preferably has a solid electrolyte, which may be yttrium stabilized zirconia (YSZ). The electrolyte is connected to a solid or liquid cathode, which is given a supply of an oxidizer such as air. An ion such as O2? passes through the electrolyte. If O2? passes through the electrolyte from the anode to the cathode, a possible reaction at the cathode may be O2+4e??2O2?. The electrochemical cell of the invention is preferably operated as a fuel cell, consuming fuel and producing electrical current.

  • Patent number: 6739456
    Abstract: An apparatus for classifying a mixture of fine and coarse particles in a fluid stream by size or density comprises a housing, a boundary layer momentum transfer device, and an inlet flow control mechanism. The housing comprises an inlet, an interior chamber, and a fine particle outlet. The boundary layer momentum transfer device comprises a plurality of disks stacked in spaced, parallel relation in the interior chamber. The disks are rotatable about a disk axis. The disks have respective central openings cooperatively defining a plenum having a closed axial end and an opposing open axial end. The plenum communicates with spaces defined between each adjacent disk to cooperatively define a fine particle flow path from the interior chamber, through the spaces, through the plenum and the open axial end thereof, and to the fine particle outlet. The inlet flow control mechanism communicates with the interior chamber and provides an adjustable inlet flow path into the interior chamber.

  • Patent number: 6517612
    Abstract: This invention is directed to a continuously cleanable, high performance filtration apparatus and a method for using the apparatus. The apparatus is a radial inflow centrifugal filtration device, which includes a filter element located within a chamber and rotatably coupled to a filtered fluid outlet in a bulkhead that abuts the chamber. The filter element is generally tubular, its side-walls encircling and, thus, defining an interior plenum. The filter element side-walls incorporate a filter media, preferably a laminated microporous membrane filter media. The filter element is rotatably coupled at the filtered fluid outlet by a seal which can maintain a seal as filter element rotates. Additionally, the device can include a boundary layer momentum transfer device made up of a plurality of stacked annular disks having central openings, each disk separated from adjacent disks by a desired gap. The central openings define a cavity in which the filter element is mounted.

  • Patent number: 5746789
    Abstract: A radial inflow centrifugal filter device for separating fine particulates from a fluid flow, including a rotatable plurality of hollow parallel disks mounted in spaced apart relationship and attached via spacers to a tube. The hollow drive tube is in flow communication with the interior hollow plenum of the disks which is at a lower pressure relative to the open space between the disks. Rotating the tube causes the disks to rotate. Particulate-laden fluid is allowed to enter the filter device at the perimeter of the rotating disks and experiences a change in momentum due to the interaction of boundary layers of fluid established on each side of every disk. The centrifugal force imparted to both the fluid and particulates causes them to be separated in opposite directions.
