Patents Assigned to J. G. Boswell Company
  • Patent number: 5834292
    Abstract: A method for producing somaclonal variant cotton plant. The method comprising providing a cotton explant, culturing the explant in a callus growth medium supplemented with glucose as a primary carbon source until secretion of phenolic compounds has ceased and undifferentiated callus is formed from the explant, culturing the undifferentiated callus in callus growth medium supplemented with sucrose as a primary carbon source until embryogenic callus is formed from the undifferentiated callus, transferring the embryogenic callus to a plant germination medium, culturing the embryogenic callus on the plant germination medium until a plantlet is formed from the embryogenic callus, transferring the plantlets to soil, growing the plantlets to produce seeds from self pollination, collecting the seeds, planting the seeds, growing the seeds under conditions to select for a desired characteristic and collecting the plants with the desired characteristics.

  • Patent number: 5040270
    Abstract: A method for treating fibrous material containing matter to be separated therefrom, the method including the steps of passing fibrous material containing the matter and having a given temperature along a path of travel in a fluid stream; and directing a jet of fluid, having a temperature substantially greater than that of the fibrous material and matter, onto the fibrous material and matter to release the matter from the fibrous material.An apparatus for treating fibrous material containing matter to be separated, the apparatus having a housing with a path of fluid movement therethrough; a system for passing fibrous material containing the matter to be separated along the path through the housing; and a system for discharging a gas, having a temperature substantially greater than that of the fibrous material and matter, onto the fibrous material and matter during passing thereof along the path to release the matter from the fibrous material.
