Patent CA-2611603-A1 (CA)
Inventor: SHISSLER ANDREW L
IPC: A61M16/00
Filed: 2006-06-13
Abstract: A gas delivery system (12) comprising a pressure generator (14), a pressure sensor (21), a control valve (20), and a processor (32). The pressure generator (14) pressurizes breathable gas (22) for delivery to a patient. The pressure sensor (21) measures a pressure difference between the pressurized breathable gas (22) and atmospheric pressure. The control valve (20) is disposed downstream from the pressure generator (14) and is constructed and arranged to control a flow rate of the pressurized breathable gas (22). The processor (32) controls the control valve (20) to bring the flow rate of the pressurized breathable gas (22) to substantially zero while the pressure generator (14) is operating and, when the flow rate is substantially zero, determines at least one of atmospheric pressure, an atmospheric air density, or a density correction factor based at least in part on the pressure difference between the pressurized breathable gas (22) and the atmospheric pressure.

Abstract: Processes for preparing racemic mixtures of 5,7,3',4'-tetra-O-benzyl-(~)-catechin and (~)-epicatechin involves (i) condensing 2-hydroxy-4,6-bis(benzyloxy)-acetophenone and 3,4-bis(benzyloxy)benzaldehyde, cyclizing the resulting compound, oxidizing the resulting compound; (ii) dihydroxylating (E)-3-(3',4'-bis(benzyloxy)phenyl)prop-2-ene-1 -ol and reducing the 1 ,2-diol; or (iii) coupling 3,5-bis(benzyloxy)phenol with (~)-3,5-bis(benzyloxy)-2-(3',4'-bis(benzyloxy)phenyl)allyl)phenol and cyclizing the resulting chalcone. A  process for preparing the benzylated epimers of catechin and epicatechin involves seven steps. 3,4-Bis(benzyloxy)benzaldehyde is coupled with 2-hydroxy-4,6-benzyloxy-acetophenone to form a chalcone. The chalcone is selectively reduced to an alkene. The phenolic group of the alkene is protected. The protected alkene is asymetrically dihydroxylated. The resulting compound is deprotected, cyclized, and finally hydrolyzed. Epimers resulting from these processes are chemically resolved or separated by chiral high pressure liquid chromatography. Also disclosed is a method for preparing enantiomerically pure 5,7,3',4'-tetra-O-benzyl-(+)-catechin from a racemic mixture using dibenzoyl-L-tartaric acid monomethyl ester. Further, disclosed is an improved process for preparing dibenzoyl-L-tartaric acid monomethyl ester.

Abstract: Nogo receptor 1 (NgR1) is a leucine rich repeat protein that forms part of a signaling complex that modulates axon regeneration. Previous studies have shown that the entire LRR region of Nogo receptor-1, including the C-terminal cap of LRR, LRRCT, is needed for ligand binding, and that the adjacent CT  stalk of the Nogo receptor-1 contributes to interaction with its co-receptors.  The present invention is directed to the use of certain Nogo receptor-1 and Nogo receptor-2 polypeptides and polypeptide fragments for promoting neurite outgrowth, neuronal survival, and axonal regeneration in CNS neurons. The invention features molecules and methods useful for inhibiting neurite outgrowth inhibition, promoting neuronal survival, and/or promoting axonal regeneration in CNS neurons.

Title: Fluid bearing and method of operation
Inventor: GRAY CHARLES L
IPC: F16C32/06
Filed: 2007-04-27
Abstract: A fluid bearing (203) includes first and second hydrostatic pads (330,331,332,334) formed in a surface of an insert (338) and positioned to exert a separating force, and a land (328) formed on the surface of the insert and configured to act as a bushing to allow rotation while the first and second pads are pressurized at less than a hydrostatic balance force. Pressurized fluid to the pads of the insert is controlled to prevent operation in full hydrostatic mode. More particularly, a separating force generated by surface force of the pads is controlled such that the separating force does not exceed a force exerted on the bearing. The fluid pressure is also controlled to keep the separating force within a selected margin of the force exerted on the bearing, to control wear of the bearing. Control of the separating force is achieved by selectively pressurizing individual hydrostatic pads, thereby effectively varying the active hydrostatic area of the bearing.
