  • Method and apparatus for removing fumigation gases from fumigated structures
    Patent number: 5565178
    Abstract: An apparatus for removing fumigation gasses from fumigated structures is provided. Air is directed from a structure through an adsorption unit and then recirculated back into the structure. A fan directs air through the adsorption unit. The adsorption unit contains an annularly shaped adsorption bed and an inner passage way and outer passage way through which fumigation gasses are directed. A lower adsorption efficiency per pass through the adsorption bed is used in conjunction with multiple passes with the method of the present invention.
    Type: Grant

  • Package for toxic fumigant material in pellet or tablet form and method of making same
    Patent number: 4653644
    Abstract: A package for the application of a fumigant material includes a first sheet having a plurality of recesses for receiving a fumigant in pellet or tablet form in each recess and a second sheet one side of which is coated with an adhesive which is applied over the openings and surrounding surface area of the first sheet and adhered thereto by heat and pressure; the material of the sheet is a spun bonded polyester which permits ingress of moisture containing atmosphere. The release of the toxic gas produced by the moisture induced decomposition of the pellets takes place at a much higher effective rate than has been the case with previous packages for similar material.
