  • Composition for chromatography
    Patent number: 4111838
    Abstract: A chromatographic material comprising an inorganic support-polysaccharide particle matrix is described. The matrix comprises an inorganic support having a high surface density of hydroxyl groups and, covalently attached thereto, insoluble particles of a polysaccharide. The free hydroxyl groups of the matrix can be activated, say, by treatment with cyanogen bromide or sodium metaperiodate, to form active sites where ligands can be attached for affinity chromatography.

    Inventors: James Robert Schaeffer, Roy Eugene Snoke, Harry Wayne Harris
  • Method for treatment of corn hulls
    Patent number: 4104463
    Abstract: Corn hulls and like materials are subjected to a treatment to obtain two fractions therefrom comprising a holocellulose fraction and a non-carbohydrate fraction.
    Type: Grant
    Filed: July 5, 1977
    Date of Patent: August 1, 1978
    Assignee: Standard Brands Incorporated
    Inventors: Richard Lee Antrim, Donald Wayne Harris
  • Process for enzymatically converting cellulose derived from corn hulls to glucose
    Patent number: 4089745
    Abstract: Corn hulls are subjected to a liquid extraction treatment whereby the major portion of the cellulose is liberated from the other constituents of the corn hulls and the resulting cellulose fraction is enzymatically treated to convert a substantial portion thereof to glucose.
    Type: Grant
    Filed: December 27, 1976
    Date of Patent: May 16, 1978
    Assignee: Standard Brands Incorporated

  • Purification of uricase
    Patent number: 4064010
    Abstract: Catalase is effectively removed from a uricase preparation by amphiphilic chromotography using as the column material cyanogen bromide-activated polysaccharide having a hydrophobic ligand attached thereto. Particularly useful hydrophobic ligands are the alkanediamines.
    Type: Grant

    Date of Patent: December 20, 1977
    Assignee: Eastman Kodak Company
    Inventors: Harry Wayne Harris, James Robert Schaeffer, Roy Eugene Snoke
  • Method for purifying cholesterol esterase
    Patent number: 4042461
    Abstract: Cholesterol esterase is purified by removal of the separable lipase in an enzyme preparation containing both cholesterol esterase and lipase activities by treatment using a hydrophobic chromatography column comprising carboxylated polysaccharide material having lower alkylamine with less than 8 carbon atoms attached thereto.
    Type: Grant
    Filed: September 10, 1976

  • Method for treatment of corn hulls
    Patent number: 4038481
    Abstract: Corn hulls are subjected to a treatment to obtain three fractions therefrom comprising a cellulosic fraction, a hemicellulose fraction and a noncarbohydrate fraction. The noncarbohydrate fraction is characterized as being an organic solvent extract comprising at least about 15 percent of the dry weight of the corn hulls and containing above about 10 percent by weight ferulic acid.

  • Digitally controlled variable conductance
    Patent number: 4009400
    Abstract: A digitally tuned active filter is disclosed. The filter is tunable by digitally controlling the variable conductance which comprises two resistors, one of which is in series with a field-effect transistor switch and those two in parallel with the other resistor. The field-effect transistor switch is switched by a digitally controlled variable duty cycle generator.
