  • Method of decolorizing water
    Patent number: 5281338
    Abstract: A method of decolorising water colored by humic or fulvic acid, such as moorland runoff water, which method comprises bringing the water into contact with chitin or alginic acid as adsorbent. The adsorbent may be recycled after use by treatment with aqueous alkaline solution followed by treatment with an aqueous acid solution.
    Type: Grant

    Inventors: Ralph Harris, Anne M. Jacques, Melanie Brown, Alexander Buchan
  • Vaccine against herpes viruses
    Patent number: 5219567
    Abstract: A vaccine against a herpes virus is prepared by infecting cells with virus, separating the nuclei of the infected cells from their cytoplasmic fraction, discarding the nuclei, fixing the polypeptide chains of the virus antigens in the cytoplasmic fraction, and precipitating those antigens, the precipitated antigens providing the active constituent of the vaccine. A characteristic strain of the virus may be used, so that vaccinated subjects can be distinguished from infected subject.
    Type: Grant
    Filed: March 19, 1990
    Date of Patent: June 15, 1993
    Assignee: The University of Birmingham
    Inventors: Gordon R. Skinner, Alexander Buchan

    Date of Patent: August 15, 1989
    Assignee: Medical Research International Ltd.
    Inventors: Gordon R. B. Skinner, Alexander Buchan
  • Preparing vaccine against Herpes simplex virus
    Patent number: 4816250
    Abstract: A vaccine against a DNA virus, for exmaple, Herpes simplex virus, is prepared by incubating a cell sample which has been infected with the virus, releasing the nuclei in the infected cell material from the cytoplasmic fraction of that material, chemically fixing the polypeptide chains in the cytoplasmic fraction, and forming a precipitate which includes the virus antigens in the cytoplasmic fraction, the precipitate providing the active constituent of the vaccine. A characteristic strain of the virus is preferred, and transfers its characteristics to the vaccine so that vaccinated subjects may subsequently be distinguished from infected subjects.
