  • Patent number: 10451576
    Abstract: A system to determine the ground impedance of a conduit system includes a conductive sheath and a resistor of known value. The conductive sheath is configured to surround a portion of a conductor housed within a conduit system. Capacitive coupling occurs between the sheath and the conductor to establish a voltage source. The resistor is electrically coupled between the voltage source and a metal component of the conduit system, and a voltage drop is read across the resistor to determine the health of the ground impedance of the conduit system.

  • Patent number: 10110146
    Abstract: A novel motor drive system has been described for use in electrostatic generator/motor systems based on the time variation of capacity of a rotating condenser comprised of segmented rotor and stator elements. It takes advantage of the fact that the motor action of such a system depends only on the rms value of the drive pulses, which therefore can be formed simply by periodically interrupting a high-frequency ac wave train. This new circuitry simplifies the drive system and takes advantage of recent developments of devices used in the art of inversion of dc voltages to high-frequency (tens of kiloHz) ac.

  • Patent number: 10046077
    Abstract: Systems and methods for dissolving ozone gas in a liquid. An embodiment can comprise a tank having an upper region, a lower region, and a discharge outlet, all disposed in a specified geometry. A pump can be coupled with a liquid inlet in order to receive a liquid therefrom and to deliver the liquid via a pipe to the upper region of the tank. The pump can be coupled with the lower region of the tank in order to receive the liquid from the tank and to recirculate the liquid to the upper region of the tank. The apparatus can include an ozone inlet to receive ozone into the tank. The ozone inlet can comprise a venturi inlet disposed on the pipe downstream of the pump. The liquid can be released from the tank and depressurized, thereby providing for the ozone to emerge from the liquid as gas bubbles. The released liquid can be selected for a two-stage gas and aqueous cleaning process.

  • Patent number: 9903248
    Abstract: An exhaust aftertreatment system for purifying an exhaust gas feedstream that is expelled from an internal combustion engine that is operable at an air/fuel ratio that is lean of stoichiometry is described. The exhaust aftertreatment system includes a barrier discharge plasma reactor that is disposed upstream relative to a catalytic reactor and electrically connected to a plasma controller. The barrier discharge plasma reactor is controlled to generate ozone from constituents of the exhaust gas feedstream when the internal combustion engine is operating at a lean air/fuel ratio and at a low temperature condition. The generated ozone reacts, in the catalytic reactor, to oxidize non-methane hydrocarbons contained in the exhaust gas feedstream when the internal combustion engine is operating at lean air/fuel ratio and at low temperature conditions.

    Abstract: The present invention generally includes an ozone generation system with a power supply that measures the rate of energy delivered to the ozone generation cell. While changing voltage, frequency or current will likely affect the rate of energy delivery, current, frequency and voltage provide a very poor and unreliable control for an ozone generation cell. It is only through control of the rate of energy delivery that consistent, reliable ozone generation is possible. Based upon the measurements of the rate of energy delivery as measured at the ozone generation cell, compared to the rate of energy delivery supplied, the rate of energy delivery supplied can be adjusted to improve ozone production and control.

The system and method involve a first and a second concentration controller in combination with an ozone generator. The first concentration controller detects an EVENT (i.e., one of the chambers in the multi-chamber tool coming on-line or off-line) and in response provides a power instruction to the ozone generator in accordance with a predictive control algorithm. The first concentration controller has a fast (i.e, about 1 second) response time. The second concentration controller is masked from the ozone generator during the EVENT, but otherwise controls the generator after an interval of time has lapsed after the EVENT. The second concentration controller has a slower response time than the first concentration controller, however the second concentration controller provides the system with long-term stability and can be used to provide updated data to the predictive control algorithm.

    Abstract: The present technology provides an illustrative method for treating air. The method includes providing untreated air and producing an oxygen-enriched sample from the untreated air. The method further includes generating ozone in the oxygen-enriched sample to produce an ozone-enriched sample and contacting the ozone-enriched sample and a fraction of the untreated air to produce a treated sample. The fraction of the untreated sample includes a fraction removed from the untreated air when producing the oxygen-enriched sample. The method also includes removing ozone from the treated sample to form a purified sample of air.

  • Patent number: 8308914
    Abstract: An electrolytic ozone cell anode spring fastening board structure includes a solid polymer electrolyte membrane (1), an anode electrocatalyst layer (2), a diffusion layer (3), frame body and support parts (5). A diffusion layer counterpiece (4) has one side attached to the diffusion layer (3), the other side of the diffusion layer counterpiece (4) equipped with a centered elevated step, which contacts the center of the convex side of a spherical spring board (6). In addition, the solid polymer electrolyte membrane (1), frame body and support parts (5), diffusion layer (3), diffusion layer counterpiece (4) and spring board (6) are held together by mechanical fastening means. It prevents a decrease in ozone generation rate in electrolytic ozone cell that can occur from the metal board deformation and thinning of the anode electrocatalyst layer.

  • Patent number: 8241563
    Abstract: An air sanitization system including a housing having an inlet and an outlet, an ozone generator disposed in the housing and positioned between the inlet and outlet, at least one fiber optic cable positioned in visible proximity to the ozone generator, a visible light detector, and a controller. The housing is configured to receive a flow of an oxygen-containing gas through the inlet, and the ozone generator generates ozone from the flow of oxygen-containing gas. The at least one fiber optic cable is configured to receive and transmit visible light from the ozone generator. The visible light detector detects an amount of visible light transmitted by the at least one fiber optic cable. The controller is in communication with the visible light detector for determining whether the amount of visible light transmitted by the at least one fiber optic cable corresponds to a failure of the ozone generator.

  • Patent number: 8211374
    Abstract: The present invention provides an apparatus 1 for the treatment of air comprising a low power corona discharge ozone generator 5,6 inside a chamber 9 having an inlet 2 and an outlet 7, and at least one air flow impeller 3 for inducing a flow of air through the chamber 9. The ozone generator 5,6 is formed and arranged for generating a restricted concentration of ozone, within an inactivating zone 10 contained within the chamber 9, through which the air flow is passed. The restricted concentration is sufficient to inactivate airborne pollutant material entrained in the air flow, yet decays sufficiently outside the inactivating zone so that the concentration of ozone in the cleaned air expelled from the apparatus 1 is at a physiologically acceptable level without the use of an ozone decomposition catalyzer.
