Patent CA-2384259-A1 (CA)
Title: Access concurrency for cached authorization information in relational database systems
Inventor: STUY MICHAEL A F
IPC: G06F16/21
Filed: 2002-04-29
Abstract: A method and system for permitting concurrent access to cached authorization information for an SQL database system. The authorization information is cached as consolidated bitmaps. A first, authorization, bitmap in the cache represents committed authorization information for a grantee and type of grantee. A second, cumulative delta, bitmap in each cache entry represents authorization information not yet committed. A cache entry state is recorded for each cache entry. Access to the cumulative delta bitmap is provided where the database agent requesting access is the agent carrying out a modification to the cached authorization information. Access to the authorization bitmap information is permitted, amongst other conditions, where a grant statement is uncommitted and the database agent requesting access is not seeking to modify the authorization
Patent CA-2388805-A1 (CA)
Inventor: HOELDERICH WOLFGANG FRIEDRICH
IPC: B01J31/16
Filed: 2000-11-03
Abstract: Ionic liquids are immobilised on a functionalised support which carries or contains one component of the ionic liquid, or a precursor to such a component. The ionic liquid may be immobilised via the anion by treating a support with an anion source, e.g. an inorganic halide, before the ionic liquid is applied or formed. Alternatively the ionic liquid may be immobilised by having the cation covalently bound to the support, e.g. through silyl groups, or incorporated in the support by synthesising the support in the presence of a suitable base. The immobilised ionic liquids are of use as catalysts for example for the Friedel-Crafts reaction.

Title: A single use syringe
Inventor: KIEHNE BRUCE LEIGH
IPC: A61M5/32
Filed: 2001-02-22
Abstract: A single use syringe (10) has a needle (14) which is biased back into the barrel (11) but which is prevented from doing so by a holding means (26) which has an outer part (25) and an inner part (27) which are connected together by a frangible portion (29).

Title: Procede pour detecter en temps reel et ainsi empecher une corrosion localisee
Inventor: MARTIN ROY
IPC: G01N17/02
Filed: 2001-06-21
Abstract: Cette invention se rapporte à un nouveau moyen permettant de déterminer la nature (le type) d'une corrosion en temps réel. En identifiant une corrosion localisée au moment du début d'une fissuration, on peut effectuer un choix en temps réel d'un ou de plusieurs inhibiteurs appropriés et on peut introduire une ou des concentrations efficaces de ces inhibiteurs dans une solution électrolytique, avant la propagation de la corrosion localisée. En intégrant ces informations dans un système d'amenée d'inhibiteur de corrosion, on peut empêcher efficacement la corrosion avant sa propagation, préservant ainsi l'intégrité du système. Ce procédé utilise un mode opératoire dans lequel les valeurs de bruit électrochimiques (ECN) et de polarisation linéaire (LPR) sont traitées pour comparer le mode de corrélation des signaux de corrosion. Une divergence entre les vitesses de corrosion indique la formation d'une corrosion localisée, alors qu'une continuité de l'aspect du signal indique une corrosion généralisée.

Title: Determination of supplemental fuel requirement and instantaneous control thereof involving regenerative thermal oxidation
Inventor: RUHL ANDREAS C H
IPC: F23G5/50
Filed: 2001-12-07
Abstract: A control system for a regenerative thermal oxidizer in which contaminated air is first passed through a hot heat-exchange bed and into a communicating high temperature oxidation (combustion) chamber, and then through a relatively cool second heat exchange bed. The apparatus includes a number of internally insulated, ceramic filled heat recovery columns topped by an internally insulated combustion chamber. Contaminated air is directed into heat exchange media in one of said columns, and oxidation is completed as the flow passes through the combustion chamber. From the combustion chamber, the now clean air flows through another column containing heat exchange media, thereby storing heat in the media for use in a subsequent inlet cycle when the flow control valves reverse. The resulting clean air is directed via an outlet valve through an outlet manifold and released to atmosphere or is recirculated back to the oxidizer inlet. A combustible fuel such as natural gas is added to the inlet-contaminated air prior to its entry into the hot heat exchange column when the contaminant concentration in the contaminated air falls below a predetermined level. The oxidizer is preferably integrated with a web dryer, such that hot aire from the combustion chamber is supplied to the dryer.
