Filed: 2001-06-18
Abstract: La présente invention concerne un procédé permettant vérifier systématiquement le rendement en polymérisation de catalyseurs potentiels. A cet effet, on commence par faire réagit un catalyseur potentiel avec au moins un premier monomère dans des conditions de polymérisation, puis on évalue le rendement en polymérisation du premier monomère considéré. On utilisera alors cette évaluation comme base de prédiction pour le rendement en polymérisation du catalyseur pour au moins un deuxième monomère. En l'occurrence, ces deux monomères sont différents l'un de l'autre, le premier monomère étant une oléfine autre que l'éthylène. Ce procédé donne des résultats utiles, concrets et tangibles présentant une valeur particulière pour l'identification de catalyseurs convenant à la polymérisation et la copolymérisation oléfinique.
Patent CA-2382993-A1 (CA)
Title: Attenuated recombinant rabies virus mutants and live vaccines thereof
Inventor: MEBATSION TESHOME
IPC: C12N7/04
Filed: 2002-04-22
Abstract: The present invention describes recombinant RV mutants comprising a combined mutation in two different parts of the viral genome, involving the P and the G genes.  The mutations in the P gene preferably encompass residues 139 to 170, more preferably residues 139 to 149, most preferably residues 143-149. The mutation can be a substitution or deletion of one or more amino acids in the above region, as well as combinations of deletion and substitution. Preferred mutants according to the invention may be obtained by deleting residues 143 to 149 or 139 to 149 of the phosphoprotein (P) of rabies virus and simultaneously replacing the Arg at position 333 of the glycoprotein into another residue, preferably Asp instead of Arg. Surprisingly, when these mutations were introduced into rabies viruses lacking Arg at position 333 of their G protein, a dramatic reduction in pathogenicity for suckling mice was observed. This unexpected finding has a profound advantage in developing more safe live attenuated rabies vaccines. The mutation in the G gene may comprise a mutation of the Arg333 colon into a colon that differs by one, two or three nucleotides from said Arg333 colon. Preferably the mutants are mutants of a RV strain in which all three nucleotides of the Arg333 colon are substituted.

Title: Reduced misting oven cleaner
Inventor: LENTSCH STEVEN E
IPC: C11D1/94
Filed: 1994-08-04
Abstract: Spray-on cleaners that can be delivered by pump or pressurized gas aerosol spray head have been known to cause respiratory distress in the form of a chocking mist. The chocking mist associated with aerosol use can be reduced or eliminated by formulating surface cleaning compositions that can be dispensed through a spray head resulting in an aerosol or mist droplet having a mean particle size greater than about 200 µm. We have found that typical spray-on cleaners have a mean particle size less than about 175 µm and, depending on the concentration and degree of irritation of strong base or strong acid components, can cause severe respiratory distress. Preferred thickeners have been found for use in the non-chocking aerosol or mist compositions.

Title: Integrated water treatment and flue gas desulfurization process
Inventor: GHOSH MAINAK
IPC: C02F5/02
Filed: 2002-12-20
Abstract: The invention relates to an integrated water treatment and flue gas desulfurization process in which a water stream containing hardness minerals is subjected to a water treatment process using a precipitating alkali agent to precipitate the hardness minerals and to produce a softened water stream. Thereafter, the softened, alkaline water stream is utilized in a scrubber to scrub a flue gas containing sulfur dioxide to produce a sulfur-lean flue gas. The invention is particularly useful in a steam-based bitumen recovery operation where bitumen, sour produced gas or other sulfur containing fuels are burned for producing steam for bitumen recovery. More specifically, the associated produced water from the bitumen recovery process is softened for re-use and for utilization as a scrubbing agent for high-sulfur containing flue gas arising from the steam generators. The process provides an economically favorable process while minimizing waste disposal requirements.

Title: A method for supervised teaching of a recurrent artificial neural network
Inventor: JAEGER HERBERT
IPC: G06N3/08
Filed: 2001-10-05
Abstract: A method for the supervised teaching of a recurrent neutral network (RNN) is disclosed. A typical embodiment of the method utilizes a large (50 units or more), randomly initialized RNN with a globally stable dynamics. During the training period, the output units of this RNN are teacher-forced to follow the desired output signal. During this period, activations from all hidden units are recorded. At the end of the teaching period, these recorded data are used as input for a method which computes new weights of those connections that feed into the output units. The method is distinguished from existing training methods for RNNs through the following characteristics: (1) Only the weights of connections to output units are changed by learning - existing methods for teaching recurrent networks adjust all network weights. (2) The internal dynamics of large networks are used as a "reservoir" of dynamical components which are not changed, but only newly combined by the learning procedure -existing methods use small networks, whose internal dynamics are themselves competely re-shaped through learning.
