Patent CA-2312097-A1 (CA)
Inventor: BEREAN GEORGE S
IPC: B63H9/06
Filed: 1998-11-25
Abstract: An improved lift creating sail and sail system where a substantially rectangular mainsail (2) made up of panels forms an aerodynamically efficient airfoil that is supported at approximately its center on a pivot so that is has three degrees of freedom. The mainsail can be tilted at hartships, rotated along a yaw axis, and tilted for and aft to create lift and minimum drag. An optional jib sail (3) that can track the motion of the mainsail also produces lift. The mainsail (2) and jib sail (3) can be trimmed and positioned along three degrees of freedom to obtain maximum lift and minimum drag as well as a stable system. The effect of this sail system is to increase the speed of the boat by 15-25 %.

Patent CA-2316294-A1 (CA)
Inventor: ZHANG XIAOMING
IPC: C12P41/00
Filed: 1998-10-23
Abstract: A process for resolving racemic diesters of (R,S)(~)-5-hydroxy-3-(4'-hydroxyphenyl)-1,1,3-trimethylindane is disclosed. The process utilizes a microbial enzyme derived from Chromobacterium viscosum to catalyze the enantioselective and regioselective hydrolysis of the (S)(-)-enantiomer of the racemic mixture to its corresponding monoester at a faster rate than the (R)(+)-enantiomer. A substantially pure (S)(-)-indane monoester is thereby formed, while the (R)(+)-indane diester remains unreacted. The (S)(+)monoester and the (R)(+)-diester can then be hydrolyzed using conventional techniques to form optically active (R)(+)- and (S)(-)-5-hydroxy-3-(4'-hydroxyphenyl)-1,1,3- trimethylindane enantiomers for use as monomers in the synthesis of chiral polymers.

Title: Systeme de batterie redox a flux continu et pile cellulaire
Inventor: BROMAN BARRY MICHAEL
IPC: H01M8/04
Filed: 1998-01-28
Abstract: L'invention concerne un système de batterie redox à flux continu constitué d'une pluralité de cellules montées en série électrique délimitée par un arrangement empilé et répétitif d'un séparateur intercellulaire conducteur ayant généralement une fonction bipolaire, d'une électrode positive, d'une membrane échangeuse d'ions, d'une électrode négative et d'un autre séparateur intercellulaire conducteur. On met en oeuvre le système de batterie redox en faisant circuler un électrolyte de demi-pile positif contenant de ions réductibles et oxydables d'un premier couple à travers les compartiments contenant les électrodes positives, et un électrolyte de demi- pile négatif contenant de ions réductibles et oxydables d'un deuxième couple à travers les compartiments contenant les électrodes négatives en cascade dans un mode d'écoulement de courant contraire ou convergent. La différence de la tension d'élément entre la première cellule et la dernière cellule de la pile est sensiblement réduite et les courants de dérivation sont en grande partie éliminés, d'où une efficacité faradique globale accrue. On décrit une architecture à pile cellulaire munie de conduits permettant d'effectuer les deux écoulements de contre-courant en cascade des électrolytes positif et négatif. L'emploi alterné de membranes cationiques et anioniques compense le cheminement déséquilibré de l'eau à travers les membranes.

Title: Method of making an ohmic contact to p-type silicon carbide, comprising titanium carbide and nickel silicide
Inventor: VASSILEVSKI KONSTANTIN VALENTI
IPC: H01L21/04
Filed: 2000-10-06
Abstract: A method of producing an ohmic contact to p-type silicon carbide comprising two layers, the first one comprising nickel silicide and the second one comprising titanium carbide is disclosed. The deposited layers are annealed to convert at least a part of deposited metals to nickel silicide and titanium carbide. The contact is formed by reaction between the metals and the semiconductor, and thus the in-situ simultaneous formation of metal silicide and carbide suppress the release of excess carbon at the contact interface. Noble metals may be deposited preferably in between titanium and nickel to improve the contact morphology.
