  • Patent number: 5806120
    Abstract: A system for treating laundry with ozone including a controller that receives a load signal based on a wash load selection. The controller varies an output potential from a variable power supply to an ozone generator in response to the load signal. The ozone generator produces different levels of ozone corresponding to the output potential. A wash liquor is drawn out of a laundry machine and sent through a filter past an injector adjacent a venturi. The injector entrains ozone from the ozone generator into the wash liquor and the wash liquor is returned to the laundry machine.

  • Patent number: 5564225
    Abstract: An improved method and apparatus for packaging roses or other flowers (or other "botanicals"; e.g., cedar fronds) so that they are preserved in a fresh state for an extended period. A modified atmosphere packaging (MAP) machine seals the flower in a container under vacuum, and a vial which is attached to the stem of the flower includes a solution which releases preservative and rehydration materials from an absorbent medium so that the materials flow through the stem and outwardly through the pores of the flower and its leaves. An ion balanced environment stabilizes pollen and color while prolonging the shelf life of the cut flowers.

  • Patent number: 5433927
    Abstract: An ozone generator includes an inner electrode formed of a mass of helical windings through which an elongate electrical conductor extends. The elongate conductor is preferably a metal strip having opposing rows of sawtooth projections extending outwardly from opposing side edges of the strip. The metal strip also preferably has a generally sinuous shape in longitudinal cross-section. An outer electrode is separated from the inner electrode by a dielectric tube. The inner and outer electrodes produce ozone gas using an electrical corona discharge in the presence of an oxygen containing gas. A second tube surrounds the first dielectric tube to capture ozone generated at the outer electrode. A pair of endcaps directs gas flow adjacent the outer conductor and through the inner conductor.

  • Patent number: 5427693
    Abstract: An apparatus includes a frame carrying a process tank, ozone generating tubes, a venturi, and an infusion chamber for treating water with ozone. A pump circulates water from the process tank and through the venturi to the infusion chamber. The infusion chamber is connected immediately downstream from the venturi. The infusion chamber has a predetermined pressure to produce a head space and thereby generate a relatively large number of bubbles of relatively small size to enhance the mass transfer of ozone into the water. A length of tubing is connected downstream from the infusion chamber to enhance the contact time between the ozone and the contaminants. An ozone generator tube including an inner electrode formed of a mass of helical windings produces a high concentration of ozone from a cooled air supply.

  • Patent number: 5409673
    Abstract: An apparatus and method for producing a high concentration of ozone gas using an electrical corona discharge in the presence of an oxygen containing gas. The generator includes a first and second electrode separated by a dielectric tube, each electrode being adapted to be connected to a high voltage AC power supply. The first electrode preferably has a lattice structure and surrounds the dielectric tube. The second electrode is formed of a mass of helical windings with a series of curved surfaces thereon. The second electrode is positioned within the dielectric tube underlying the first electrode. The curved surfaces of the helical windings create a corona therefrom. In one embodiment of the ozone generator, the mass of helical windings is provided by at least one milled sponge having a plurality of layers of a continuous helical winding extending in a generally spiral direction about a central axis of the milled sponge.
