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.

Ozone sterilizer and method for ozone sterilization

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.

Ozone generator and method for ozone generation

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. A method of coating a metal electrode for use in an ozone generator may include plasma spraying (and the steps leading up to effect of plasma spraying), or dip or spin coating followed by sintering.

Dielectric coating for ozone generator electrodes

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. Cooling fluid, such as nitrogen gas, may be passed through an interior passageway and outside the outer electrode either co-current or countercurrent to the general direction of oxygen gas flow.

Swirl flow ozone generating

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.

Monitor for ozone, hydrogen peroxide and other gases in fluids

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.

Ozone sterilizer

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.

High efficiency ozone generator for sterilizing, bleaching and the like

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.

An educational device for teaching dental hygiene is disclosed. The device consists of a model of a human head having a mouth with teeth, moveable jaw and sensors imbedded in the teeth. A microprocessor is provided and the sensors are connected to the microprocessor. A probe and a toothbrush are connected to the microprocessor and may be held in the hand of an operator adjacent the teeth to simulate brushing, flossing, and other dental activities. Light emitting diodes of different colors are imbedded in the teeth and connected to the microprocessor to indicate conditions of the teeth. A speaker and a memory device are connected to the microprocessor to audibly discuss the procedures carried out with the information fed to the microprocessor from the teeth, and a command unit is provided to actuate the jaw to open and close the mouth.

Dental technique training device

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.

Apparatus for continuous electrochromatographic separation

A continuous chromatographic separation is effected by a column packed with finely divided chromatographic particles, the nature of which depends on the materials to be separated. In the case of liquid systems, the cylinder containing chromatographic packing is substantially horizontal and is spun to develop substantial centrifugal force. Preferably, the cylinder is of suitable porous material, such as a ceramic of the type used for filtration. The liquid, having dissolved or suspended therein the constituents to be separated, is introduced at one end under substantial pressure, for example by a pump, which, preferably, rotates with the cylinder. The cylinder is supported along its length by non-corrosive, such as stainless steel, rings. The rings are held together by through-bolts and, if necessary, spacers. In the case of a porous ceramic cylinder, the pores are small, and there are stationary troughs at the peripheries of each pair of rings which receive liquid coming out. For horizontal cylinders there are drain holes in the lower trough which permit the liquid to go into collectors at predetermined points along the cylinder. The sample, which is introduced under some pressure, moves along the chromatographic packing, and separation of various constituents is effected chromatographically. In the case of gas chromatography, the cylinder may be of metal with suitable rows of openings along the periphery of segments formed by supporting rings.
