  • Pharmaceutical compositions for intranasal spray administration of ketorolac tromethamine
    Patent number: 6090368
    Abstract: A pharmaceutical composition of a water soluble drug admixed with an aqueous bioadhesive cellulosic polymer containing microcrystalline particles. When sprayed (via a conventional spray device) into the nose, drug molecules are retained in contact with the nasal membrane. The drug composition comprises ketorolac tromethamine in an aqueous nasal polymeric spray formulation that without the addition of any permeation enhancer will promote drug absorption and provides absolute drug bioavailability greater than 90%.

  • Data cartridge library system architecture
    Patent number: 5682276
    Abstract: A storage system (10) is disclosed that provides random access storage/retrieval of data on data cartridges within the storage system (10). In one embodiment, the storage system (10) includes a storage array (20), a player/recorder device (22), and a cartridge transport device (40). The player/recorder device (22), a guard device (80) and the transport device (40) are positioned on substantially opposite sides of the storage array. The transport device (40) moves cartridges between the storage array (20) and the player/recorder device (22). The guard device (80) pushes a prolapsed data cartridge back into the storage array (20) and/or limits the distance a data cartridge will prolapse from the storage array (20).
