Title: Cryptographic authentication process
Inventor: VALLEE LUC
IPC: G06F21/34
Filed: 2002-06-24
Abstract: A cryptographic authentication method including a first step during which a first entity (A) to be authenticated sends an authenticator second entity (B) a message protected by a cryptographic algorithm and a secret key (K<SUB>s</SUB>). During a second step, the second entity (B), after receiving said message, carries out operations selected from the group comprising completely verifying the authentication of the received protected message by means of said cryptographic algorithm and a verification key (K<SUB>v</SUB>), delaying said complete verification, partly verifying said authentication, partly verifying said authentication and completing the verification subsequently, and omitting to verify said authentication. One of these operations is chosen as a function of the degree of certainty that the second entity (B) wishes to obtain as to the authentication of the first entity (A) and being concealed from the first entity (A).

Title: Procede de fabrication de membranes filtrantes allongees et modules a membranes
Inventor: COTE PIERRE
IPC: B01D63/02
Filed: 2002-12-09
Abstract: L'invention concerne un procédé d'allongement d'une fibre creuse dans la fabrication d'une membrane filtrante allongée à partir d'un précurseur, consistant à enrouler la fibre creuse autour d'une structure et à modifier la structure de manière qu'au moins certaines parties de la fibre creuse soient forcément allongées. La fibre creuse peut être enroulée, par exemple, autour de deux ou de plusieurs supports et la distance entre les supports adjacents peut augmenter. Des premières parties de la fibre creuse sont ainsi allongées selon un premier allongement et poreuses selon une première porosité, et des secondes parties de la fibre creuse ne sont pas allongées ou sont allongées selon un second allongement inférieur au premier allongement et restent non poreuses ou deviennent poreuses selon une seconde porosité inférieure à la première porosité. La membrane peut être faite dans un module. Des secondes parties des membranes sont situées sur des points où les membranes évacuent le matériau de remplissage ou sur des spires de boucles de fibres, s'il y a lieu. Dans divers modes de réalisation, la fibre est remplie dans des modules avant ou après son allongement. Certains procédés de remplissage consistent à appliquer un adhésif thermofusible aux secondes parties. Dans certains modes de réalisation, lesdites membranes sont entièrement faites de matériau plastique et peuvent être facilement recyclées.

Inventor: CHEN GANG-FUNG
IPC: C09J201/00
Filed: 2002-11-15
Abstract: One aspect of the present invention is an adhesive composition formed from two packs. One pack includes an isocyanate-functional prepolymer formed by reacting a polyisocyanate with an alcohol (e.g., polyol). The isocyanate equivalents from the polyisocyanate exceed the hydroxyl equivalents from the alcohol. The second pack is an aqueous polymer emulsion. These two packs are combined to form the novel adhesive composition. Another aspect of the invention is a method for joining together two surfaces of wood products by application of an adhesive thereto. The first step in this method is to mist with water the wood product surfaces to be joined. An adhesive composition then is applied to the misted wood product surfaces. Alternatively, the water misting can be replaced with an aqueous emulsion being part of the adhesive composition. Finally, the adhesive composition is cured.
