  • Publication number: 20120193292
    Abstract: The present invention relates to devices for treating liquids, and methods for treating liquids, particularly by using such devices. Reticulated electrode structures with a high proportion of surface area to volume are formed with at least two metals, and are coupled in arrays to an electrical driving signal such as an alternating and/or direct current voltage source, for ion exchange with a liquid to be treated, to produce, e.g., potable water.

  • Patent number: 7678210
    Abstract: A process for mitigating shear induced particle migration of highly filled explosive suspensions during injection loading of the explosive suspension into a confined container that includes monitoring particle migration within the highly filled explosive suspension and correcting flow parameters effective to reduce the particle migration.

  • Patent number: 4706581
    Abstract: A fossil fuel furnace reactor is provided for simulating a continuous processing plant with a batch reactor. An internal reaction vessel contains a batch of shale oil, with the vessel having a relatively thin wall thickness for a heat transfer rate effective to simulate a process temperature history in the selected continuous processing plant. A heater jacket is disposed about the reactor vessel and defines a number of independent controllable temperature zones axially spaced along the reaction vessel. Each temperature zone can be energized to simulate a time-temperature history of process material through the continuous plant. A pressure vessel contains both the heater jacket and the reaction vessel at an operating pressure functionally selected to simulate the continuous processing plant. The process yield from the oil shale may be used as feedback information to software simulating operation of the continuous plant to provide operating parameters, i.e.
