Patent application numberDescriptionPublished
20110305726Infectious Bronchitis Vaccines Derived From IB-qx-like Vaccine Strains - The present invention relates to infectious bronchitis (IB) viruses derived from a recently identified genotype of IB virus known as IB-QX, or from viruses that are genetically related to IB-QX, herein referred to as IB-QX-like viruses. The IB viruses of the invention may be live and attenuated or inactivated. Live, attenuated IB viruses of the invention may be produced by serial passaging of an IB-QX-like virus. The IB viruses of the invention are useful for, inter alia, vaccines against IB-QX and IB-QX-like viruses. Heretofore, known vaccine strains of IB viruses have proven insufficient to protect against infectious bronchitis caused by IB-QX and IB-QX-like viruses.12-15-2011

20120072737SYSTEM FOR ESTABLISHING A CRYPTOGRAPHIC KEY DEPENDING ON A PHYSICAL SYSTEM - In systems for establishing a cryptographic key depending on a physical uncloneable function (PUF) it may be a problem that internal information correlated with the cryptographic key is leaked to the outside of the system via a side-channel. To mitigate this problem a cryptographic system for reproducibly establishing a cryptographic key is presented. The system comprises a physical system comprising a physical, at least partially random, configuration of components from which an initial bit-string is derived. An error corrector corrects deviations occurring in the initial bit-string. Through the use of randomization the error corrector operates on a randomized data. Information leaking through a side channel is thereby reduced. After error correction a cryptographic key may be derived from the initial bit-string.03-22-2012

20120037489APPARATUS AND METHOD FOR PURIFYING A LIQUID - For purifying a liquid, the liquid is caused to evaporate in a cyclone in a recirculation circuit. Vapor is discharged via a discharge channel in which a compressor is included. In a heat exchanger downstream of the compressor, supplied vapor condenses and heat thereby released is transferred to liquid in the recirculation circuit. A liquid inlet of the cyclone is placed and directed for delivering a jet having a directional component tangential with respect to an inner surface of the cyclone. The liquid inlet has a section shaped such that in operation the delivered jet is a flat jet having a cross section which in a direction parallel to a nearest generatrix of the inner surface of the cyclone is greater than in a direction perpendicular thereto. The jet contacts the inner surface of the cyclone before drop formation occurs in the jet. A method for purifying a liquid is also described.02-16-2012

20080274953Method of Preparing a Protein Aggregate and a Pharmaceutical Preparation - The invention relates to a method of preparing a protein aggregate, wherein an aqueous protein solution is acidified with a pH that lies above the isoelectric point of the protein. In accordance with the invention, a first protein, which through acidification is able to form a protein aggregate, is acidified in the presence of a second protein in the aqueous solution in order to form a coaggregate comprising the first and second protein, wherein the second protein under identical temperature conditions and pH does not form a protein aggregate in the absence of the first protein. Acidification preferably occurs with the aid of CO11-06-2008
20100115988Treatment of Molybdate Containing Waste Streams - The invention is directed to a process for the treatment of an aqueous solution comprising sodium carbonate and/or sodium bicarbonate and sodium molybdate, said process comprising freeze crystallising the solution at the eutectic freezing point thereof and recovering substantially pure ice crystals, substantially pure sodium carbonate and/or sodium bicarbonate and an aqueous product solution containing dissolved sodium molybdate.05-13-2010
20100186444Crystallizer With Internal Scraped Cooled Wall and Method of Use Thereof - Apparatus for separating solids from a mixture or solution, comprising an outer wall provided with an inlet for the mixture or solution and provided with a first discharge for discharging an ice slurry and a second discharge for discharging a salt slurry, one or more raking or scraping elements for scraping solidified material from cooled wall portions which are cooled at or close to a temperature where the mixture or solution solidifies, preferably the eutectic temperature thereof.07-29-2010
20110138547METHOD OF DYEING A SUBSTRATE WITH A REACTIVE DYESTUFF IN SUPERCRITICAL OR NEAR SUPERCRITICAL CARBON DIOXIDE - The present invention relates to a method of dyeing a substrate with a reactive dyestuff in supercritical or near supercritical carbon dioxide, said substrate being selected from the group consisting of cellulose fibres, modified cellulose fibres, protein fibres and of synthetic fibres, or any combination thereof, wherein the method comprises the subsequent steps of: 06-16-2011
