Abstract:
A floor scrubbing apparatus includes a reservoir for an aqueous salt solution disposed in the floor scrubbing apparatus. An immersion device comprising a submersible housing with at least two iridium-coated electrodes spaced apart from each other within the submersible housing is adapted to be immersed into the reservoir. The floor scrubbing apparatus also includes a control module electrically coupled to the electrodes, wherein the control module controls application of electricity to cause a first electrode to be positively charged and a second electrode to be negatively charged.
Abstract:

A shaft is positioned in the housing such that the shaft is free to rotate around the longitudinal axis of the shaft and such that both ends of the shaft are located inside of the housing.
Abstract:
A scrubbing muffler for internal combustion engines comprises coaxial counter-rotating disk pairs stacked in a cascade. Acoustic pulses are attenuated by doing work and dissipated by the circuitous path through the dynamic cascade. A motor and/or Venturi effect from slipstream over a vehicle assists exhaust and reduces backpressure for greater fuel economy. Exhaust gas fed at the axis is sheared between the disks of the first stage of the cascade as it passes radially outward into a shrouding tank disposed about the cascade. Vortex rebound at the tank wall advects flow radially inward back through the workspace between the first stage disks to axial extraction as feed for the second stage of the cascade. N2 and H2O, along with CO and NO, can pass radially inward to successive stages. Soot and CO2 stay in the tank. NO and CO are reduced at a Faraday disk cathode.
Abstract:
Continuous nanotube synthesis by vortex deposition occurs in an axially-fed shear reactor comprising coaxial counter-rotating disk impeller/electrodes charged as anodes. Nanotube evolving ends, charged as cathodes, point toward the anode axis of rotation and protrude into the space between the anodes. Radial vortices in a shear layer of the space, between the boundary layers on the impeller/electrodes, spin cations to be deposited on evolving nanotube ends approximately at the vortex axis, so deposition is by swirling cathode fall. The evolved nanotubes are extracted mechanically, and they conduct electrons from charging means to charge the evolving ends as cathodes. The preferential synthesis of metallic carbon nanotubes is due to the greater resistance of non-metallic structures such as graphite or semiconductive structures. Ozone serves to oxidize non-metallic structures and to functionalize the loose ends of nanotube fragments. Dopants can be added to the evolving nanotubes by introduction of dopants at the periphery because the evolving ends are maintained in stable locations. Or dopants can be added by the simultaneous decomposition of gases (for example, carbon dioxide and nitrogen gas) within the reactor or in an external reactor.
Abstract:
A method and device for conversion of water into hydrogen peroxide, wherein a corona discharge zone is generated between a rotating electrode formed as a hollow rotor of a centrifugal fan and a fixed electrode. The rotating electrode is rotated relative to an insulation layer of the fixed electrode, and high voltage AC power is applied to the fixed electrode while conveying vapor through the corona discharge zone. In one aspect, the novelty resides in using the rotating electrode for conversion of water to vapor. In another aspect, conductivity between the two electrodes induces electrolysis, which is used for high voltage AC transmission to the rotating electrode.

Abstract:
A halogen generator produces a halogen sanitizing agent to sanitize water in a spa or other water feature. A coaxial wall fitting desirably couples the halogen generator to the water feature. The halogen generator desirably includes a bipolar electrolytic cell in which a center electrode plate rotates between stationary anode and cathode plates. The bipolar electrode includes a plurality of vanes which motivate water flow between the anode and the cathode. The vanes on the rotating electrode also produce a flow of water through the generator. In this manner, the bipolar electrode functions as a impeller to pump water through the halogen generator. The vanes are positioned between the electrode and cathode, and are sufficiently spaced from the cathode to inhibit scale formation on the cathode. The vanes, however, generally do not contact the cathode when rotating. The rotational direction of the electrode relative to the cathode may be reversed periodically and/or the gap spacing between electrode and the cathode may be decreased periodically to enhance removal of scale.

An electrolytic cell comprises an electrolyzing chamber having a pair of terminal electrodes located therein and adapted to be connected to the poles of a D.C. source. A plurality of bipolar electrodes in the form of parallel flat annular discs are located in the chamber between the terminal electrodes and are rotatable about a common central axis through their centers. An electrolyte inlet is located radially outwardly of the bipolar electrodes. In order to provide vigorous scouring of the bipolar electrodes with relative low fluid flows to the cell, the electrolyte inlet comprises one or more elongate slots formed in the cylindrical wall of the chamber and extending in a direction generally perpendicular to the planes containing the bipolar disc electrodes.
