  • Apparatus for removing radioactive antimony from waste streams
    Patent number: 7153416
    Abstract: A method and related apparatus for monitoring and eliminating gas build-up in an anion exchange column comprised of an anion exchange material placed within a vessel and a liquid layer comprising water contaminated by at least antimony passing through said vessel, which method comprises maintaining said anion exchange material within said liquid layer by allowing gases produced by a reaction of said liquid layer with said anion exchange material to be released from said anion exchange vessel though a valve or other gas release mechanism.
    Type: Grant
    Filed: March 17, 2006
    Date of Patent: December 26, 2006
    Inventors: Luis M. Penafiel, Pedro M. Buarque de Macedo

  • Protection of living systems from adverse effects of electric, magnetic and electromagnetic fields
    Patent number: 5566685
    Abstract: Methods and apparatus for inhibiting the adverse effect of an ambient time varying field having an electric component and/or a magnetic component on a living system. To provide protection, the field to which the system is exposed is caused to be one wherein at least one of the characteristic parameters of said field to which the living system is exposed is changed within time intervals of less than 10 seconds. Living systems which are benefitted include humans.

  • Protection of living systems from adverse effects of electric, magnetic and electromagnetic fields
    Patent number: 5544665
    Abstract: The embodiments of the inventions disclosed in this application develop a `protection` electric, magnetic or electromagnetic field or fields which are either superimposed upon an ambient field which is detrimental to the health of living systems, or incorporated into the electrical circuit of the device which is generating the detrimental field. Either arrangement is successful in `confusing` living cells, and thereby reducing the harmful effects of the otherwise detrimental field.
