  • Publication number: 20040192578
    Abstract: A process for producing new anticancer drugs such that the drugs can be administered in a nontoxic, proto-drug form and, subsequent to a time delay which allows for differential concentration in the targer cancer or invasive tissues or cells, the non-toxic drug is then modified by an activation drug to selectively provide toxic levels of a pharmacologically active agent to the target issue.
    Type: Application

  • Patent number: 6098563
    Abstract: The invention relates to a spillage protection system for a storage vessel in the event a breach of the hull occurs. The system comprises sheets of lath work panels extending from longitudinal and transverse supporting members of the vessel hull for forming sub-compartments therein. The sheets of lath work panels are comprised of a plurality of apertures therein for providing characteristics of strength and porosity to the structure. The system further comprises a distribution system extending through the hull of the vessel and into each of the sub-compartments. The distribution system originates at a reservoir which supplies a foamable cast-cure plastic material to the distribution system and effectively delivers the foamable cast-cure plastic material to a sub-compartment adjacent to an area of the hull experiencing the breach.

  • Patent number: 4036141
    Abstract: A hypervelocity ammunition round in which a spin stabilized artillery projectile contains a plurality of subcaliber gun tubes for launching subcaliber spin stabilized projectiles from the artillery projectile at a predetermined point in its trajectory, as the artillery projectile performs as a moving gun platform to more effectively defeat a multiplicity of targets through the kinetic energy impact of the subcaliber projectiles.
    Type: Grant

  • Patent number: 4036140
    Abstract: A hypervelocity ammunition round in which a fin stabilized artillery projile contains a plurality of subcaliber gun tubes for launching subcaliber fin stabilized flechette projectiles from the artillery projectile at a predetermined point in its trajectory, as the artillery projectile performs as a moving gun platform to more effectively defeat a multiplicity of targets through the kinetic energy impact of the subcaliber projectiles. The round utilizes a traveling charge arrangement in launching both the artillery projectile and each of the subcaliber projectiles.
