  • Methods and systems for testing tires of vehicles to quantify transient tire force and moment responses
    Patent number: 8006550
    Abstract: A method for testing a tire of a vehicle that includes the steps of creating a first condition comprising a first slip angle of the tire, obtaining a first set of data regarding performance of the tire under the first condition, creating a second condition comprising either a second slip angle or lateral displacement of the tire, obtaining a second set of data regarding performance of the tire under the second condition, and determining the transient response of the lateral force and aligning moment of the tire, using the first set of data and the second set of data.
    Type: Grant

  • Sewage sludge treatment with gas injection
    Patent number: 5248419
    Abstract: This invention relates to a sewage sludge treatment system resulting in an oxygenated and/or ozonated treated sludge containing substantially no pathogens. The system includes apparatus and a process for mascerating raw sludge, adjusting the pH to about 2.5 to about 3, adjusting the solids content to about 2.5% to about 4%, adjusting the temperature, if necessary, to about 20.degree. C. to about 40.degree. C., mixing an oxygen-rich gas, such as oxygen and/or ozone with the sludge as the sludge is mixed or recirculated through a hyperbaric vessel and simultaneously injecting the oxygen-rich gas into a combination gas and sludge mixing and dispersing assembly in an upper portion of the hyperbaric vessel. Such injection causes mixing of the gas and sludge and dispersement of such mixture in a plurality of streams to atomize and oxygenate the sludge.
