Patent CA-2341963-A1 (CA)
Inventor: LEEDS RICHARD
IPC: A23B4/32
Filed: 2001-03-23
Abstract: A method and system for controlling a temperature of products in a rotating drum employs nozzles to deliver a heat transfer fluid in a more efficient manner. The heat transfer fluid nozzles which are positioned around the interior of the rotating drum deliver the heat transfer fluid to the product in the drum when the nozzles are positioned under the product and prevent delivery of the heat transfer fluid when the nozzles are not under the product. This improves the efficiency of the heat transfer system substantially over known systems in which the heat transfer fluid is delivered continuously and a large portion of the heat transfer fluid is exhausted from the rotating drum before contacting the product. The heat transfer system also provides a self cleaning system for the nozzles which deliver the heat transfer fluid to the drum.

Abstract: Un système permettant les communications de téléphonie en réseau de données DNT par une page WEB comprend un serveur Web (28) hébergeant une page WEB interactive ayant un port Internet, en tant que lien dans la page WEB adapté au lancement d'un module téléphonique compatible DNT, et un module téléphonique compatible DNT associé au lien. Dans ce système, lors de la sélection du lien par une personne accédant à la page WEB sur l'Internet (13) utilisant une plate-forme informatique, une instance du module téléphonique PI est téléchargée vers une plate-forme informatique, et un appel PI est lancé vers une adresse PI préstockée et associée au lien. Le réseau DNT peut être l'Internet (13). Dans un mode de réalisation préféré, le système étudie tout d'abord les caractéristiques matérielles et logicielles de la plate-forme informatique et annexe les caractéristiques déterminées à l'instance du module téléphonique PI à télécharger. Alors, le module téléchargé s'auto-lance et s'auto-configure, puis il lance l'appel associé. Dans certains modes de réalisation, le module disparaît après un seul appel et ainsi il sert de valideur instantané pour la téléphonie PI.

Title: Adhesives with improved rivet properties and laminates using the same
Inventor: MALLYA PRAKASH
IPC: B32B7/12
Filed: 1999-09-23
Abstract: Acrylate copolymer pressure-sensitive adhesive constructions are described which provide excellent retention of rivet properties.  Tenting around rivets is minimized even after undergoing thermal aging while in contact with additive rich films like PVC. This is achieved by the inclusion of a synergistic amount of an N-vinyl lactam monomer and acid monomer with the bulk of the monomers being an alkyl acrylate save and/or methacrylate esters. A concomitant increase in cohesive strength is also achieved which affords good removal characteristics. The use of appropriate adhesive blends is further disclosed which allows retention of these features while also improving cold temperature properties.

Abstract: Rotor blades for wind power installations are known in many different forms. In a wind power installation the rotors or the rotor blades thereof represent the main source of sound. For reasons relating to acceptance and noise prevention laws, the aim should/must be that of minimising the levels of sound emission as wind power installations are often also set up in the proximity of residential accommodation. The levels of sound emission which hitherto occur with a wind power installation or a wind power converter also mean that wind power installations are faced with resistance from populated areas because of the sound they produce and for that reason such installations can be accepted sometimes with difficulty or not at all as authorities responsible for planning permission refuse permission for wind power installations because of the existing environmental requirements, noise also being an environmentally polluting factor.   Therefore the object of the invention is further to improve the noise emission of wind power installations.   Wind power installation rotor blade comprising means for reducing the sound produced by a rotor blade, wherein the means is formed by a fluid-repellent layer and/or surface which is provided at least on a surface portion of the rotor blade.

Title: Preparation of catalysts and use thereof for fischer-tropsch hydrocarbon synthesis
Inventor: DAAGE MICHEL A
IPC: B01J29/072
Filed: 2000-10-06
Abstract: Catalysts useful for Fischer-Tropsch hydrocarbon synthesis are prepared by adding an aqueous solution of a carbonate salt to an aqueous solution of one or more catalytic metal component salts, under mixing conditions, to form a slurry containing a hydroxy metal carbonate precipitate of the catalytic metal. This slurry is heated to drive off CO2 and change the nature of the hydroxy metal precipitate and form a second precipitate which is composited with the zeolite component of the catalyst. The composite, which may also contain promoter metals and other components, is dried to a moisture content of from 6 to 15 wt. % and then reduced in hydrogen to form the catalyst.
