  • Patent number: 6312740
    Abstract: A method and apparatus, for applying electrostatically charged particles of an edible coating material to a surface of a food product to be coated, incorporates a fluidizing hopper for containing the material. The hopper includes an agitating system including an agitator blade and lifting blades to stir and lift the material while air is forced through a microporous fluidizing plate into the material. The fluidized material is withdrawn from the hopper through a venturi pump and supplied to an application gun. The application gun includes a corona discharge through which the fluidized material is forced to create charged particles of the fluidized material. The fluidized particles are directed to a food product item to be coated. The quantity of coating material is predetermined and is precisely controlled by shutting off the air pressure supply to the venturi pump to avoid excessive overspray of the particles.

  • Patent number: 6296358
    Abstract: An ocular fundus imager automatically aligns fundus illuminating rays to enter the pupil and to prevent corneal reflections from obscuring the fundus image produced. Focusing the produced fundus image is automatically performed and is based upon the fundus image itself. A head restraint for the patient undergoing examination is in the form of a pair of spectacles which is not only easy to use accurately but significantly reduces the gross alignment between the optical system and the patient's pupil.

  • Patent number: 6290424
    Abstract: A segmented ring mounting (5) for retaining cylindrical components (2, 3) one within the other in a fluid-operated percussion drill tool, such as a downhole rock drill. The ring mounting also has application to other interengaging cylindrical components which are subject to heavy wear or pressure loading, such as compressors, pumps, borehole tools, casings and drillpipe mountings. The retaining ring (5) seats a smaller diameter cylindrical component (3) within a larger diameter cylindrical component (2), wherein one of the components is formed with a groove (12) or shoulder for seating the retaining ring in use, the ring being capable of radial compression and expansion so as to expand radially into the seating groove or shoulder for retaining the components one within the other in use.

  • Patent number: 6287893
    Abstract: A chip scale package design for a flip chip integrated circuit includes a redistribution metal layer upon the upper surface of a semiconductor wafer for simultaneously forming solder bump pads as well as the metal redistribution traces that electrically couple such solder bump pads with the conductive bond pads of the underlying integrated circuit. A patterned passivation layer is applied over the redistribution metal layer. Relatively large, ductile solder balls are placed on the solder bump pads for mounting the chip scale package to a circuit board or other substrate without the need for an underfill material. The back side of the semiconductor wafer can be protected by a coating for mechanical strength during handling. A method of forming such a chip scale package at the wafer processing level is also disclosed.

  • Patent number: 6287551
    Abstract: A solution or gel composition containing activated chlorine dioxide and phosphates, such as disodium hydrogen phosphate, sodium dihydrogen phosphate, trisodium phosphate, and sodium monofluorophosphate, is disclosed for treating herpes virus. The preferred concentration ranges are between about 0.005% to about 2.0% chlorine dioxide, and between about 0.02% to about 3.0% of a phosphate compound. The phosphate compound retards escape of chlorine dioxide in the pH range of 6.0 to 7.4, at which pH chlorine dioxide becomes activated and releases sufficient chlorine dioxide to reduce motility and become lethal to the involved micro-organisms.

  • Patent number: 6280190
    Abstract: A socket for removably receiving a dental saliva ejector tube includes a central body having a first end forming a port for being coupled to a vacuum hose. The central body includes a passage extending therethrough from the first end toward a second opposing end. An elastic sleeve is secured over the second end of the central body for receiving the end of the ejector tube. A pair of spreader members are secured to the elastic sleeve. A pair of levers are pivotally secured about the central body and are actuated by the user to pull the spreader members apart, thereby distending the elastic sleeve to more easily receive the dental saliva ejector tube. To prevent the ejector tube from becoming dislodged during use, a rib may extend about the lower end of the ejector tube.

  • Patent number: 6278920
    Abstract: A computerized method for quantifying confidence in a replacement schedule for components that must be routinely replaced within a fleet of aircraft or like equipment includes programming a computer to accept predetermined input data, including anticipated life expectancy T, indicated reliability R1, the population P of the component in the fleet, and the number of failed units F replaced over a time increment t. The method computes the minimum-mean-time-between-removals &thgr;1, and the upper limit on unreliability Pu based upon such input data. The computer compares two or more of such factors to a series of Gamma Confidence Level look-up tables, and either determines a Gamma Confidence Level for the user, or prompts the user to modify the input data so that a Gamma Confidence Level can be determined. If the resulting Gamma Confidence Level is too low, the anticipated life expectancy T is reduced, and the method is repeated.

  • Patent number: 6269678
    Abstract: A leak detector includes an off-center mounted metering pin cooperating with a single cross-hole in a poppet valve to accommodate adjustment of the flow rate past the metering pin by rotating the poppet valve about its longitudinal axis. A flow director, cooperating with the poppet valve, directs all flow into the leak detector directly into the line during initial flow into the leak detector. A piston, responsive to line pressure, is sized smaller in diameter than the poppet valve to cause the line pressure to increase rapidly and significantly during the leak sense mode and which size permits reduction in size and weight of the leak detector.
