Title: Substrates for immobilizing and amplifying dna, dna-immobilized chips having dna immobilized on the substrates, and method for amplifying dna
Inventor: TAKAHASHI KOJIRO
IPC: C12Q1/68
Filed: 1999-02-08
Abstract: Substrates for immobilizing DNA, etc. to give DNA libraries, etc.; and chips appropriately usable in amplifying DNA, etc. by PCR amplification. The PCR  amplification is effected by using highly conductive solid substrates for immobilizing DNA. These substrates are surface-modified with chemicals having polar groups at the terminals. Use of the DNA-immobilized chips having DNA  immobilized on these substrates makes it possible to amplify DNA within a short time in the PCR method.

Title: Combustion engine air supply system
Inventor: NEMSER STUART MARSHALL
IPC: F02D21/02
Filed: 1999-02-16
Abstract: A method of operating an internal combustion engine (21) employs a selectively gas permeable membrane unit (10) to provide either oxygen or nitrogen enriched air to reduced NOx emissions, lean burn limit, increase power, and reduced cold start emissions. The method includes separating air into an oxygen enriched fraction and nitrogen enriched fraction with a membrane unit; and feeding the nitrogen enriched fraction to the engine. The membrane has an oxygen/nitrogen selectivity of at least 1.4 and a permeability to oxygen of at least 50 barrers. The membrane is formed from an amorphous copolymer of perfluoro-2,2-dimethyl-1,3-dioxole being at a temperature below the glass transition temperature of the copolymer. A cylindrical module (10) having many parallel hollow fiber structures (33) is used.

Abstract: Le chlorure de benzyldiméthyl {2-[2-(p-1,1,3,3-tétraméthylbutylphénoxy)éthoxy]éthyl} d'ammonium (BTD) constitue la base de solutions pour lentilles de contact qui contribuent étonamment bien à réduire le nombre et la diversité des micro-organismes susceptibles d'infecter des lentilles de contact, qu'elles soit du type souple ou rigide perméable au gaz. De plus, on a constaté que certains composés naturels, seuls ou en combinaison avec des agents chimiques, pouvaient être intégrés à des solutions ophtalmiques, notamment à des solutions pour lentilles de contact, afin d'en renforcer et d'en compléter l'action anti-microbienne, le pouvoir nettoyant et la mouillabilité ou encore d'atténuer l'irritation des yeux. La solution de base pour lentilles de contact comprend une concentration efficace de BDT (de préférence à raison de 1 à 100 ppm) avec des produits végétaux naturels possédant des activités complémentaires de celles du BDT, dans un diluant isotonique tamponné au moyen d'un tampon physiologiquement acceptable dans une plage physiologiquement naturelle.

Inventor: SPILLMAN DAVID M
IPC: H01M50/609
Filed: 2001-10-12
Abstract: In primary cells, the addition of gaseous carbon dioxide to the nonaqueous electrolyte has beneficial effects in terms of minimizing or eliminating voltage delay and reducing Rdc build-up when the cell is subjected to pulse current discharge conditions. For secondary systems, carbon dioxide provided in the electrolyte benefits cycling efficiency. The problem is that carbon dioxide readily degases from an electrolyte prepared under an ambient atmosphere. To prevent this, the carbon dioxide-containing electrolyte is prepared and stored in a carbon dioxide atmosphere. Also, the thusly prepared electrolyte is filed into the casing in a carbon dioxide-containing atmosphere. This prevents degassing of the additive from the electrolyte.
Patent CA-2359792-A1 (CA)
Title: Hemming machine
Inventor: BAULIER DOMINIQUE
IPC: B21D39/02
Filed: 2001-10-23
Abstract: A hemming machine is disclosed having a base, a nest adapted to support a part to be hemmed, a nest carrier which supports the nest and in which both the nest and nest carrier are vertically movably mounted to the base. At least one hemming die is laterally slidably mounted to the base and movable between an extended position in which the die overlies a portion of the nest, and a retracted position in which the die is spaced laterally outwardly from the nest. A lock unit selectively locks the nest carrier against vertical movement relative to the base in at least one, and preferably two positions, so that, with the nest carrier locked against movement relative to the base, inflation of a hydraulic bladder sandwiched between the nest and nest carrier displaces the nest vertically upwardly from the carrier so that the part carried by the nest is compressed against the hemming dies and performs the hemming operation. Preferably, a single drive shaft not only displaces the nest and nest carrier, but also powers the hydraulic circuit to inflate the bladder and thus upwardly displace the nest relative to the nest carrier with an amplified force required to achieve the final flattening of the hem.

Title: Drilling method
Inventor: MOYES PETER BARNES
IPC: E21B21/08
Filed: 2000-02-25
Abstract: A drilling method in which a rotary drill bit is mounted on a tubular drillstring (32) extending through a bore comprises:  drilling through a formation (33) containing fluid at a predetermined pressure; circulating drilling fluid down through the drill string (32) to exit the string at or adjacent the bit, and then upwards through an annulus (50) between the string and bore wall; and adding energy to the drilling fluid in the annulus at a location above the formation (33). The addition of energy to the fluid in the annulus (50) has the effect that the pressure of the drilling fluid above the formation (33) may be higher than the pressure of the drilling fluid in communication with the formation and that predetermined differential may be created between the pressure of the formation fluid and the pressure of the drilling fluid in communication with the formation.
