  • Vaccines comprising antigenic polypeptides of Taenia ovis
    Patent number: 5618542
    Abstract: This invention relates to polypeptide antigens of T.ovis suitable for use in vaccines to protect ruminants against infection by cestode parasites, The antigens are preferably obtained by expression of DNA coding therefor in a recombinant host cell. Aspects of the invention include DNA encoding the antigens, vectors containing the DNA and hosts which express the antigens.The invention also provides antibody and DNA probes for use in identifying protective antigens of cestode parasites other than T.ovis.

  • Stable forms of antigenic Taenia ovis polypeptides
    Patent number: 5366728
    Abstract: Stable forms of Taenia ovis peptide antigens, such as portions of a T. ovis oncosphere antigen which runs as a 47-52 kDa doublet, are suitable for use in vaccines to protect ruminants against infection by cestode parasites. The antigens are preferably obtained by isolation and expression of the DNA encoding them in recombinant host cells. Aspects of the invention include DNA encoding T. ovis antigens, vectors containing such DNA and host cells which express the T. ovis antigens.

  • Locking device for boat motor
    Patent number: 5309742
    Abstract: A locking device for locking an outboard motor onto a boat. The locking device includes a housing of greater length than a line formed between the clamping screws holding the motor onto the transom of the boat. A slot is formed in one side of the housing, and is closed on both ends, permitting only transverse sliding application of the housing onto the clamping screws, with the screw handles being received by and confined within the slot. The locking device also includes a padlock, at least one leg of the shackle of that padlock being insertable through a corresponding leg opening formed for that purpose in the housing. The leg opening is positioned so that the handles are thereby trapped in the slot. The padlock thereby locks the shackle into the body so as to impede unauthorized removal of the housing from the clamping screws, thus forming a stop to prevent sliding removal of the housing from the screws.
