Abstract: A method of sanitizing a passenger cabin includes excluding people from the passenger cabin and substantially sealing the passenger cabin such that air inside the passenger cabin is prevented from exiting the passenger cabin. An ozone enriched atmosphere is created inside the passenger cabin by generating ozone and directing the ozone into the passenger cabin to increase an ozone concentration of the atmosphere inside the passenger cabin to at least a minimum concentration. The ozone enriched atmosphere is circulated through the passenger cabin and air circulation system thereof for a sanitation period calculated to be sufficient for sanitation. The ozone concentration of the atmosphere inside the passenger cabin is then reduced to a level safe for human occupation.

Abstract: An apparatus for processing biomedical waste comprises a waste input container having an input door in a top thereof and an output door in a bottom thereof. A shredder is mounted under the output opening and is operative to shred waste to a desired maximum size. A processing chamber is located under the shredder such that, when the output door is open, solid waste deposited in the waste input container passes through the output opening and through the shredder, and shredded waste drops into the processing chamber. Ozone gas is directed into the processing chamber, and an ozone indicator indicates ozone concentration. Exhausts are selectively operative to exhaust the atmosphere from the processing chamber and waste input container.

Abstract: In a method of treating a substantially continuous flow of liquid waste in a series of decontamination tanks, the flow is directed into a tank and when liquid waste in the tank reaches a desired level the flow is directed into a next tank of the series. Ozone is bubbled through the waste in the tanks and the waste is agitated. When a disinfection period is complete in a tank, the treated liquid waste is drained into a disposal conduit that may be connected to a conventional sewer line. A sufficient number of decontamination tanks is provided such that a tank is available to receive the flow of liquid waste at all times.

Abstract: A method of sterilizing seeds comprises heating the seeds to substantially 95° C. or higher and maintaining same at that temperature for substantially 30 minutes. Preferably a combination of steam and microwaves is used to maintain the temperature. Dampening the seeds with steam and water at the start of the process helps the microwaves work more efficiently in maintaining temperature. The method further comprises treating the seeds with ozone which functions both to sterilize seeds as well as to sterilize pathogenic organisms and to degrade residual herbicides, pesticides and like chemicals that may be present in a seed sample. An auger conveyor (7) carries the seed through the process. Temperature sensors (13) monitor the temperature of the seeds and control the speed of the auger so that the seeds are maintained at substantially 95° C. for substantially 30 minutes prior to exiting the output end of the auger conveyor (7).

Abstract: A coupler for use in replacing a corroded coupler on a buried water line valve without extensive soil excavation is disclosed. A pole having a cotter pin removal tool is provided to remove the cotter pin holding a corroded coupler in place about the valve. A rod having a fastener mounted on its lower end is releasably attachable to the water line valve. The rod carries a sleeve which slidably carries a latching device which is movable from an upper position in which the fastener carried by the rod is mountable on the water line valve, and a lower position in which the fastener is locked in position, allowing the valve to be rotated. The latching device carries a fastener mateable to a fastener carried by the pole, which allows the latching device to be moved between the upper and lower positions.
