  • Patent number: 6589314
    Abstract: A size preferential electrostatic agglomerator is provided for agglomerating small particles with larger “carrier” particles. The agglomerator includes an inlet for receiving a gas flow, a separator for separating the gas flow into flow streams based on the size of the particles therein, an ionization region for imparting an opposite electrical charge to each of the flow streams, an agglomeration region receiving the flow streams to facilitate the agglomeration of the oppositely charged particles, and an outlet for exhausting the gas flow containing agglomerated particles to facilitate collection, processing or other activity on the agglomerated particles. The present invention provides an efficient system for gathering large amounts of small particles in a gas flow.

  • Patent number: 6547987
    Abstract: The present invention relates to a solvent for use in extracting oil from an oil bearing material, such as soybeans, with the solvent resulting in the selective extraction of a triglyceride rich oil, which contains 95% or greater triglycerides and non-polar constituents, with the solvent comprised of a hydrocarbon, preferably hexane, and a fluorocarbon, so that the solvent has a viscosity less than 2.6 centipoise and a polarity of less than 0.1. The present invention also relates to a method of using the solvent to extract the triglyceride rich oil, with the method including preferably extracting the oil at a temperature ranging between 35° C. and 55° C., and then preferably cooling resulting miscella to a temperature ranging between 15° C. and 25° C.

  • Patent number: 6516284
    Abstract: The invention detects loft time and/or speed of a vehicle and/or person during activities of moving and jumping. A loft sensor detects leaving the ground and returning to the ground. A microprocessor subsystem converts the sensed information to determine a loft time. A display shows the recorded loft time to a user of the system. A speed sensor can detect speed for selective display to the user, and height may also be determined during airtime.

  • Patent number: 6508903
    Abstract: A method for forming a securing label including affixing a security activating material to a substrate to form a sub-assembly label, attaching the sub-assembly label to a top label material, and cutting the top label material to form a top label where the sub-assembly label and the top label form the securing label. Attaching of sub-assembly layer includes inserting the sub-assembly layer between a paper layer and a carrier layer of the top label material which have been separated from each other and then remarried after insertion.

  • Patent number: 6499000
    Abstract: The invention detects loft time and/or speed during activities of moving and jumping. A loft sensor utilizes a spectrum of information to detect leaving the ground and returning to the ground. A microprocessor subsystem converts the sensed information to determine a loft time. A display shows the recorded loft time to a user of the system. In addition, a speed sensor can detect the vehicle's speed for selective display to the user, and height may also be determined during airtime.

  • Patent number: 6424088
    Abstract: Signs including electroluminescent lamps are described. In accordance with one embodiment of the present invention, electroluminescent lamps are coupled to a sign by first forming a rear electrode on a front surface of the sign. After forming the rear electrode on the sign, a dielectric layer is screen printed over the rear electrode, and a phosphor layer is screen printed over the dielectric layer. A layer of indium tin oxide ink is then screen printed to the phosphor layer to form an EL lamp.

  • Patent number: 6405879
    Abstract: An apparatus for holding and displaying cards including a plurality of vertical panels having at least one pair of opposed slits defining a pocket for holding the cards. Each slit has an upper end, a lower end and an aperture at either the upper end or lower end. The aperture is operatively configured to allow the pocket to expand to thereby accept a greater number of cards. The apparatus further comprises at least one support having a nodule for each vertical panel. Each nodule is configured to be coupled with the aperture of each vertical panel such that the plurality of vertical panels are interconnected by the support.

  • Patent number: 6399123
    Abstract: The present invention relates to a method for producing a treated animal feed having a comparatively higher metabolizable energy value and fewer oligosaccharides than in untreated feed, with the present method including the steps of adding an enzyme at ambient conditions to the animal feed and allowing the enzyme to hydrolyze the oligosaccharides. The present invention also relates to the resultant animal feed.
