  • Patent number: 6607648
    Abstract: An aqueous composition including silica particles with a particle size distribution and particle structure that improve the water retention and exchange characteristics of the aqueous composition is provided. The aqueous silica composition includes silica network particles and water. The silica network particles comprise main particles and bridging particles that form chains between adjacent main particles. The main particles have a particle size greater than the particle size of the bridging particles. Because of the presence of the silica network particles, the aqueous composition is capable of wetting a hydrophobic substrate more than pure liquid water. The silica network particles are generated in water by a method in which an aqueous sodium silicate solution is subjected to vigorous agitation in air, followed by periods of circulation through magnetic fields of alternating direction and further periodic agitation exposed to the air. An apparatus for carrying out the method is provided.

  • Patent number: 6593588
    Abstract: A sensor for detecting changes in a variety of conditions is provided, including temperature, chemical conditions including pH and ion levels, biological antigens, radiation levels, electrical field and pressure applied to the sensor. The sensor body is formed from a material which incorporates an evenly dispersed matrix of light-scattering elements. A light source emits light into the body to form an effective optical cavity in which the light is scattered by the matrix. One or more receivers detects the intensity of scattered or integrated light inside and/or outside of the optical cavity. The matrix and/or the sensor body are composed of materials which reduce or increase the density of light-scattering elements, depending on the conditions applied to the matrix. An increase in the density of the light-scattering elements results in a corresponding increase in the integrated intensity of light received by the receiver, when the receiver is positioned within the optical cavity.

  • Publication number: 20020029970
    Abstract: This invention relates to the enhancement of chemical reactions by applying a high frequency electric field to a material. The frequency and amplitude of the electric field are selected in accordance with the properties of the reacting components in the bulk of chemical reactor. In general, the high frequency range is determined by the dielectric properties of reactant(s), that is, at any given temperature, when, for example, the specific conductivity starts to grow from its low frequency value. Typically, frequencies in the range of 100 kHz to 200 MHz or greater are suitable for the enhancement of the reactions. An electric field of any shape having Fourier components that when applied to a chemical process exhibits growth in the real part of conductivity relative to the low frequency value is of particular importance.

  • Patent number: 6203710
    Abstract: A liquid decontamination system has a liquid treatment chamber having a liquid input and output and a gas input and output. A plurality of electrodes are positioned to place a voltage across the liquid treatment chamber and the liquid therein. A plurality of magnets are also positioned adjacent the electrodes for placing a magnetic field across the chamber and liquid therein. As the contaminated liquid is fed through the liquid treatment chamber, a predetermined gas, such as nitrogen, ozone, oxygen, or hydrogen peroxide, are fed into the contaminated liquid while simultaneously having the electric and magnetic fields applied to the liquid. The liquid leaving the treatment chamber is fed to a flush tank which removes contaminates and agglomerated solids therefrom.

  • Patent number: 6162364
    Abstract: A method and system for diamagnetic manipulation of an object in a surrounding medium in a low gravity environment is provided. The system can be used in various applications such as containerless materials processing, protein crystal growth, and particulate filtering. If the application requires directional manipulation of the object, at least one magnet or electromagnet is required. The object is repulsed by the magnet if the object is more strongly diamagnetic than the surrounding medium. If the object is less diamagnetic than the surrounding medium, however, then the object is effectively attracted to the magnet. For an application that requires suspension of the object, two oppositely polarized magnets are used to generate an appropriate magnetic field gradient to suspend the object in a location where opposing field vectors generated by the two magnets cancel each other out, producing a net field strength of zero.

  • Patent number: 5954933
    Abstract: An electrostatic fluid filtration system of the present invention is designed to remove contaminants from liquids thereby refreshing their functionality and extending their useful life. This system reduces to commercial practice a myriad of partially attained and less efficient techniques of filtration by focusing upon economic, environmental, and health factors as well as simplicity of manufacture, use and maintenance. Several generic embodiments are identified for cooking oils, fuels, lubricants and solvents, all of which have been successfully demonstrated in commercial operating environments. Proven magnetic and electrostatic phenomenologies are integrated in a controlled system that is electronically and physically adaptable to the viscosity and dielectric properties of various fluids as well as contaminant characteristics.

  • Patent number: 5679257
    Abstract: A waste water treatment system is illustrated which can be configured to be portable and which minimizes the addition of solids to be disposed of through the use of ozone for contaminant reduction to basic elements after the pH value of the waste water to be treated is properly adjusted. This ozone in one stage is combined with ultrasound to cause coagulation and precipitation. In another stage, ozone and ultraviolet light are used in a reduction process. Ion alignment using a magnetic field and an electrochemical flocculation process to which the waste water is subjected causes further coagulation and precipitation. As designed, the system can operate continuously with redundancy at appropriate points so that removal of solids from the filtration units can occur simultaneous with the overall decontamination process.

  • Patent number: 5616250
    Abstract: An improved system and novel components and methods for treating waste waters contaminated with a variety of commercial, municipal, and/or industrial contaminants. A mixing vessel according to the invention comprises upper and lower mixing chambers connected by an intermediate tubular section and a fluid exit tube running coaxially down the center of the intermediate tubular portion. The fluid stream to be treated flows in a spiral pattern vertically through the vessel, providing turbulent flow. The flow stream may be subjected to electric or magnetic fields. In one embodiment, streams of the fluid to be treated and of an ionized coagulant are combined prior to entry into the vessel; in another embodiment, the incoming flow stream is combined with the coagulants in the mixing vessel. The incoming flow may be split between annular passageways to improve mixing. Magnetite particles may be generated in situ and added to the flow stream to further encourage coagulation in the presence of a magnetic field.
