  • Patent number: 5177358
    Abstract: A solid state stripper for stripping H.sup.- to H.sup.O is provided that includes a very thin solid state material such as polyvinylidene chloride, mica, and cellophane that is moved at a predetermined speed in front of an accelerated beam of negative ions to cause the negative ions to be stripped to form neutral ions as they pass through the solid state stripper material.
    Type: Grant

    Inventors: Thomas G. Roberts, Larry J. Havard, Jr., Edward L. Wilkinson
  • Patent number: 4923151
    Abstract: A power generation system utilizes an electromagnetic tether having a three conductor, coaxial configuration which allows the circuit to be closed internal to two orbiting objects. An outer cylinder of the tether is a conductor which is used to cut or pass through the earth's magnetic field to produce a voltage output. A cylinder within the outer cylinder is made of a metal such as soft iron and is used to shield a central conductor from the earth's magnetic field. The two outer cylinders are insulated from the center conductor except at one of the tethered objects where they are electrically connected. This causes the end of the center conductor to be at the same electrical potential as the tethered object when there is an infinite load. Useful power is produced at the other object, which may be a space ship, when a switch is closed and the potential is between the outer cylinder and the center conductor.

  • Patent number: 4819675
    Abstract: A method and a product employed in the method for the mechanical and cheml removal of dental plaques are disclosed. The method comprises providing cotton filaments of a size suitable for passing between teeth as a dental floss, chemically impregnating the cotton filaments by soaking in a saturated solution of potassium hydrogen tartrate and potassium hydrogen citrate, subsequently drying the chemically impregnated cotton fibers, and passing the dried chemically impregnated cotton filaments in the form of a dental floss between teeth and over the surfaces of the teeth containing plaque compositions including a calcium phosphate to thereby convert the calcium phosphate to the more soluble compounds calcium citrate and calcium tartrate which go into solution and the plaque is, thus, removed from the surfaces of the teeth.
