  • Method for utilizing tobacco stems in smoking products
    Patent number: 4076030
    Abstract: Tobacco stems are adjusted to a moisture content of at least 18 percent before subjecting them to a cutting operation of at least 25 cuts per inch. The cut stems are then expanded before subjecting them to a second cutting operation which produces particle sizes of desired dimensions.
    Type: Grant
    Filed: December 22, 1975
    Date of Patent: February 28, 1978
    Assignee: R. J. Reynolds Tobacco Company
    Inventor: Ezra Thomas Smith
  • Preparation and use of glucose isomerase
    Patent number: 4061539
    Abstract: Glucose is converted to fructose in the presence of an enzyme produced by Flavobacterium arborescens.
    Type: Grant
    Filed: October 20, 1976
    Date of Patent: December 6, 1977
    Assignee: R. J. Reynolds Tobacco Company
    Inventor: Chin Kee Lee
  • Glucose isomerization process
    Patent number: 4060456
    Abstract: Microbial cell material having a glucose-isomerizing enzyme associated therewith is subjected to flocculation conditions to produce a flocculated aggregate containing the cell material. Glucose syrups are brought into contact with the flocculated aggregates and a portion of the glucose is thereby converted to fructose in the presence of the glucose-isomerizing enzyme.
    Type: Grant
    Filed: October 14, 1975
    Date of Patent: November 29, 1977
    Assignee: R. J. Reynolds Tobacco Company
    Inventor: Margaret E. Long
  • Aggregate of flocculated cells
    Patent number: 3989597
    Abstract: Microbial cells having active enzymes associated therewith are subjected to flocculation conditions to produce a flocculated whole cell aggregate that is useful in effecting enzyme-catalyzed chemical transformations. Substrates are brought into contact with the flocculated cell aggregates where they undergo chemical transformations in the presence of active enzymes associated with the cells.
    Type: Grant
    Filed: October 14, 1975
    Date of Patent: November 2, 1976
    Assignee: R. J. Reynolds Tobacco Company
    Inventors: Chin K. Lee, Margaret E. Long
  • Aggregate of dried flocculated cells
    Patent number: 3989596
    Abstract: Microbial cells having active enzymes associated therewith are subjected to flocculation conditions to produce a flocculated whole cell aggregate that is subsequently dried. The dried aggregate is useful in effecting enzyme-catalyzed chemical transformations. Substrates are brought into contact with the flocculated cell aggregates where they undergo chemical transformations in the presence of active enzymes associated with the cells.
    Type: Grant
    Filed: October 14, 1975
    Date of Patent: November 2, 1976
    Assignee: R. J. Reynolds Tobacco Company
    Inventor: Margaret E. Long
  • Enzymatic process using immobilized microbial cells
    Patent number: 3935069
    Abstract: Microbial cells having active enzymes associated therewith are flocculated in the presence of certain metallic compounds to give flocculated cell aggregates exhibiting improved hardness. The cell aggregates are effective as immobilized enzyme materials which are useful in enzymatic processes, particularly those which are of the continuous type.
    Type: Grant
    Filed: December 23, 1974
    Date of Patent: January 27, 1976
    Assignee: R. J. Reynolds Tobacco Company
    Inventor: Margaret Esther Long
