  • Patent number: 4908188
    Abstract: A system for treating articles, preferably with a sterilizing, gas is disclosed. The system includes a chamber into which the articles are received and valves for supplying the sterilizing gas to the chamber and for removing the gas from the chamber after a predetermined time period. The sterilizing gas is generated on site from at least two components, thus minimizing problems in the transportation of the gas to the location. The sterilizing gas generated on site is preferably chlorine dioxide and the two components may be chlorine gas and sodium chlorite. The system includes a programmed microprocessor controller for controlling the valves executing a predetermined sequence of instructions. The predetermined sequence of instructions define a state diagram for the system having a plurality of successive states. In order to provide for system safety, the controller preferably employs a plurality of abort states to which the system returns in the event of a failure.

  • Patent number: 4347127
    Abstract: An improved method and apparatus for froth flotation separation of the components of a slurry, having particular utility for the beneficiation of coal by the flotation separation of coal particles from impurities associated therewith such as ash and sulfur. In this arrangement, a primary spray nozzle is positioned above a flotation tank having a water bath therein, and sprays an input slurry through an aeration zone into the surface of the water. The spraying operation creates a froth on the water surface in which a substantial quantity of particulate matter is floating, while other components of the slurry sink into the water bath. A skimming arrangement skims the froth from the water surface as a cleaned or beneficiated product. Moreover, a recycling operation is provided wherein particulate materials which do not float after being sprayed through the primary spray nozzle are recycled to a further recycle spray nozzle to provide a second opportunity for recovery of the recycled particles.
