  • Low temperature field producer
    Patent number: 5122699
    Abstract: A process for the formation of a force field comprising cooling at least one crystal selected from potassium tartrate, cesium nitrate, rubidium nitrate, tartaric acid, cadmium nitrate and thorium nitrate to a temperature below about 110K. The force field comprises an electric field and a mass attraction field which maintains its intensity over long time periods. The crystal is encapsulated in, e.g., nonconductive epoxy.

  • Low temperature force field producer
    Patent number: 5107161
    Abstract: A process for the formation of a force field comprising cooling at least one crystal selected from potassium tartrate, cesium nitrate, rubidium nitrate, tartaric acid, cadmium nitrate and thorium nitrate to a temperature below about 110K. The force field comprises an electric field and a mass attraction field which maintains its intensity over long time periods. A method is also provided for establishing a force field at a location remote from the cooled crystal by means of an electrical connection to the cooled crystal by an insulated electrical conductor. The invention includes a device for forming the force field.
