Title: Oxidation of glycoside substituted taxanes to taxol or taxol precursors and new taxane compounds formed as intermediates
Inventor: MURRAY CHRISTOPHER K
IPC: A61K31/337
Filed: 1993-11-02
Granted: 2006-04-18
Abstract: A process for the conversion of glycoside substituted taxanes to taxol and related compounds that can serve as precursors to taxol. The process includes the oxidation of glycoside substituted taxanes to convert the glycoside to the hydroxyl group. The oxidation can occur in the presence of an acid or followed by treatment with acid. Application of the process to 7-xylosyl taxol ("XT") yields taxol; application to other glycoside substituted taxanes forms compounds that can serve as precursors for taxol. The process includes the formation of certain new taxol related intermediate compounds having a hemialdal at the C-7 site on the taxane ring, which hemialdal can then be converted to taxol or taxol precursors. Since glycoside substituted taxanes are isolated with taxol from naturally occurring biomass, their conversion to taxol using the process of the present invention significantly improves the total yield of taxol from natural sources.

Granted: 2006-01-31
Abstract: A machine readable code in a form such as a bar code (10) (fig. 2) uses self-addressed address/data packets which can be positioned in arbitrary orders and configurations (fig 1), <IMG> Additional benefits, such as ability to use extended scan angles (26) for decoding and reduction in required code management data, also result from the self-contained nature of the address/data packet components of packet codes. A sequence of data is separated into units of data which are encoded in data portions of packet s each also including an address portion which identifie s the position of such data unit relative to the original sequence of data (fig. 7 ). The individual packets may then be positioned in a wi de variety of configurations, rectangular and otherwise, with the individual packets in any order, sequential or otherwise (figs. 16 and 17). E ven where packets are aligned in an extended row, the usable scan angle range is determined by the width to height aspect ratio of indiv idual packets (fig. 3) and not limited by the much higher aspect ratio of the row of packets. Methods and systems for encoding and decodin g packet codes are described.

Title: Supporting rim structure of an open insertion end tampon applicator used to post form an insertion end of a tampon pledget
Inventor: MILLER MICHAEL L
IPC: A61F13/20
Filed: 1996-07-11
Granted: 2000-10-10
Abstract: There is provided a supporting rim structure of an open-ended tampon applicator for firmly supporting a tampon pledget that has been assembled in the applicator. The applicator supports the pledget around an intermediate section between its insertion end and its rear portion so that the insertion end is exposed outside of the applicator and the rear portion is inside of the applicator. In particular, the rim structure firmly supports the pledget against an axial force subjected to the pledget by a forming tool that forms the insertion end of the pledget into a rounded, hemispherical shape and yet readily allows the pledget to eject from the applicator. The rim structure has a shape that tapers angularly inward from the body of the applicator to form a rigid brace that counters the axial force subjected by the forming tool. Thus, while preventing the insertion end of the pledget from receding back into the applicator, the rim structure allows the pledget to easily eject from the applicator.
