Abstract: An ozone sterilizer includes a generator capable of generating a gas containing at least about 10% by weight ozone, a holding tank, a humidification chamber for receiving the ozonated gas and humidifying it to form a sterilant including at least about 8% by weight ozone at a humidity of at least about 60%, a vent for bleeding sterilant from the humidification chamber over a first catalyst, a sterilization chamber for receiving a controlled flow of sterilant which is in fluid communication with a pump for evacuating the sterilization chamber over a second catalyst, a vent for bleeding the sterilant from the sterilization chamber and a heater for providing warm air drawn into the sterilization chamber by the pump.

Abstract: An ozone generating apparatus includes an ozone generator having concentric electrodes and a means for generating a corona discharge between the electrodes, a pump for recirculating a portion of the ozone-containing gas leaving the generator through a conduit which is configured to receive a portion of the ozone containing gas, and a heat exchanger for cooling the recirculated portion of the ozone-containing gas. An oxygen-containing gas is also introduced to the heat exchanger and combined with the recirculated gas portion to form a feed gas which is chilled in the heat exchanger and then introduced into the generator.

Abstract: An ozone generator has one or both of the tube type electrodes coated with a dielectric that has high dielectric strength, high dielectric constant, and low piezoelectric activity, and can be applied with a small thickness (less than 0.5 mm). The dielectric has a mixed oxide composition having a dielectric strength of at least about 800 volts/mil, has a dielectric constant that is at least 200, and has low enough piezoelectric activity that it will not ablate, crack, or other otherwise suffer damage as a result of high voltage application over months of use. A metal electrode for use in an ozone generator has a dielectric coating on a surface thereof having a composition comprising: about 30-70% lead oxide, about 2-8% barium oxide, about 2-12% lanthanum oxide, about 3-18% titanium dioxide, about 12-40% zirconium dioxide, and trace materials.

Abstract: Ozone is generated from an oxygen-containing gas utilizing a tube-type ozone generator at significantly greater power efficiency. The oxygen is introduced into the annular passageway between the electrodes of the tube-type ozone generator at an angle (e.g. about 45.degree.-90.degree.) so that it swirls in a cyclonic flow path as it travels from one end of the annular passageway to the other. The amount of power consumed to produce a gas having about 8% ozone is roughly half of the power needed if the same conditions are applied but the oxygen gas is introduced conventionally (without swirling action, so that it travels along the dimension of elongation of the passageway). The swirling action also allows a higher concentration of ozone (e.g. 10% or more) to be achieved in the product gas compared to the same conditions when no swirling is employed.

Abstract: This monitoring invention is an improvement over the ozone (O.sub.3) and hydrogen peroxide (H.sub.2 O.sub.2) monitoring systems that are now commercially used.The manner in which this monitor measures the gas, or a gas dissolved in a liquid, is by measuring the heat energy that is released when the material to be measured is catalyzed. The detector measures the heat produced when, for example, ozone is reduced to oxygen or the hydrogen peroxide is reduced to oxygen and water by a catalytic action. This heat energy is collected and measured. The higher the temperature, the higher the concentration.

Abstract: A sterilizer having a generator of concentrated (10% +) ozone, a holding tank receiving the generator output, a sterilizer chamber fed from the holding tank, and a control maintaining ozone concentration in the tank to insure the desired ozone level in the sterilization chamber.

Abstract: An ozone generator for producing ozone at pressures of up to 10,000 psi from oxygen or oxygen containing gas, which contains two electrodes for forming a corona discharge through the input gas, the first electrode being cooled by a first cooling fluid and the second electrode being cooled by a second cooling fluid, which further contains flexible barrier means for equalizing the pressure between the cooling fluids and the input gas.

Abstract: A method of sterilization for hospital and field use in which an article to be sterilized is submerged in water and ozone, which is supplied from a separate source, is bubbled through said water and over said article so as to provide an ozone concentration in excess of water saturation alone. Such a process can be used to kill even the most difficult bacteria and spores in shorter times than ethylene oxide sterilizers and further can be used for instruments which cannot stand steam temperatures or pressure changes.

Abstract: An apparatus that performs a continuous separation of and the purification of chemical compounds by employing both the phenomena of electrophoresis and chromatography or electrophoresis alone, dependent on the material to be separated. The material to be separated has laminar flow through a chromatographic bed while subjected to an electric field from opposite side edges. The differences in molecular weight or density cause a difference in rate of flow of the components of the chemical compound so the chemical compounds have different lateral movements under the influence of the electric field and are physically separated at the outlet end of the bed.

Abstract: This invention relates to methods of removing materials from fluids, and in one embodiment includes an ionically biasable foraminous belt which moves through a multiplicity of transversals to the flow path of said fluid which are sequentially positionally counterdirectional to said flow path.
