Title: Glycosidase inhibitors and methods of synthesizing same
Inventor: PINTO BRIAN MARIO
IPC: C07H11/00
Filed: 2004-06-25
Abstract: A method for synthesizing Salacinol, its stereoisomers, and analogues, homologues and other derivatives thereof potentially useful as glycolsidase inhibitors. The compounds of the invention may have the general formula (I) or (II): The synthetic schemes comprise reacting a cyclic sulfate with a 5-membered ring sugar containing a heteroatom (X). The heteroatom preferably comprises sulfur, selenium, or nitrogen. The cyclic sulfate and ring sugar reagents may be readily prepared from carbohydrate precursors, such as D-glucose, L-glucose, D-xylose and L-xylose. The target compounds are prepared by opening of the cyclic sulfates by nucleophilic attack of the heteroatoms on the 5-membered ring sugars. The resulting heterocyclic compounds have a stable, inner salt structure comprising a heteroatom cation and a sulfate anion. The synthetic schemes yield various stereoisomers of the target compounds in moderate to good yields with limited side-reactions.

Title: Low pressure stem gas seal
Inventor: THOMPSON GRANT R
IPC: F16K31/44
Filed: 2005-04-07
Abstract: A backup stem seal for a gate valve retains pressure in the body when the valve is in the closed position. The backup seal is secondary to the main stem seal assembly (20) in the bonnet (12). It features metal-to-metal contact between surfaces (22, 24) that are radially oriented or sloping and further can contain a retaining groove (26) for a seal ring (32) in one or both the opposed metal-to-metal surfaces (22, 24).

Title: Leaching process for copper concentrates
Inventor: DIXON DAVID G
IPC: C25C1/12
Filed: 2005-05-27
Abstract: A method of leaching copper from copper sulphide-containing concentrates, such as chalcopyrite, includes using pyrite as a catalyst for ferric reduction in order to eliminate passivation of the chalcopyrite surface, the process being carried out under conditions whereby the pyrite is not materially oxidized, for example by maintaining the operating solution potential at a suitable level.
