    Abstract: Methods for the preparation of chemical intermediates in the synthesis of HIV-protease inhibitors related to and including nelfinavir mesylate are disclosed. The method of this invention comprises converting tetrohydran derivatives into oxazolines to provide key reaction intermediates for the preparation of nelfinavir. Also disclosed is a method for the preparation of a chiral amino alcohol from an epoxy-tetrahydrofuran.

    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), a guard device (80) and a cartridge transport device (40). The player/recorder device (22) 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).

    Abstract: Sintered polybenzimidazole articles are obtained by compacting a particulate, dried polybenzimidazole resin under a pressure of 2,000 to 10,000 psi in a mold, heating the formed article to a temperature in the range of 825.degree. to 950.degree. F. for at least four hours, cooling the polybenzimidazole article to below 800.degree. F. while maintaining the article under a pressure of 2,000 to 10,000 psi, and thereafter heating the constrained formed polybenzimidazole article to a temperature in the range of 825.degree. to 950.degree. F. for at least one hour.
