  • Patent number: 6077563
    Abstract: Overprintable thermoset decorating inks and methods of applying such inks to substrates are disclosed. The decorating inks include a reactive polymeric binder resin and a crystalline crosslinker. The reactive polymeric binder resin may comprise acrylics, epoxies, polyesters, urethanes and the like which possess high Tg values. The combination of high glass transition temperature resins and crystalline crosslinkers avoids the necessity of using diluents in the coating compositions. The coating composition is applied to a substrate by heating the composition to a first temperature below the curing temperature of the coating, applying the heated coating composition to the substrate, allowing the applied coating composition to cool sufficiently so it at least partially hardens, and heating the applied coating composition to a second temperature above the first temperature for a sufficient to cure the coating composition.

  • Patent number: 5925290
    Abstract: An apparatus and method are provided for mixing gas and liquid. An impeller is rotatably mounted inside a draft tube having a constricted section. Rotation of the impeller draws liquid down through the constricted portion of the draft tube. A gas delivery system introduces gas under the surface of the liquid downstream from the constricted portion of the draft tube to entrain the gas in the liquid by a venturi effect. The impeller creates a turbulent gas-liquid mixing zone and also projects liquid radially into the gas as it enters the draft tube. The gas-liquid venturi mixer is particularly suitable for treating industrial and municipal waste water, as well as various other liquids. Gases such as air, oxygen, hydrogen, and the like are efficiently dissolved in such liquids during operation of the gas-liquid venturi mixer.

  • Patent number: 5919144
    Abstract: A non-invasive apparatus and method are disclosed for measuring intracranial pressure. The intracranial measurement system transmits acoustic signals through a cranium and provides an indication of intracranial pressure based on the received acoustic signals after interaction with the brain. Properties such as acoustic transmission impedance, resonant frequency, resonance characteristics, velocity of sound and the like may be measured and correlated with intracranial pressure. The acoustic signals have typical frequencies of less than 100 kHz, for example, in the audible and sub-audible frequency ranges. The intensity of the transmitted acoustic signals used to determine intracranial pressure is relatively low, resulting in little or no health risks during short term or long term monitoring.

  • Patent number: 5916491
    Abstract: An apparatus and method are provided for mixing gas and liquid. An impeller is rotatably mounted inside a draft tube. Inlet baffles are mounted adjacent the inlet end of the draft tube in close proximity to the impeller. In addition, outlet baffles are mounted adjacent the outlet end of the draft tube in close proximity to the impeller. Rotation of the impeller draws liquid down through the draft tube and creates vortices which serve to entrain gas into the liquid. The provision of inlet and outlet baffles directly adjacent the rotating impeller produces high gas entrainment and shear rates and improves gas transfer efficiency. The gas-liquid vortex mixer is particularly suitable for treating industrial and municipal waste water, as well as various other liquids. Gases such as air, oxygen, hydrogen, and the like are efficiently dissolved in such liquids during operation of the gas-liquid vortex mixer.
