Patent CA-2291459-A1 (CA)
Title: Dynamo-electric machine stator stack forming methods and apparatus
Inventor: STRATICO GIANFRANCO
IPC: H02K1/12
Filed: 1999-12-02
Abstract: Hollow cylindrical dynamo-electric machine stator cores may be made by superimposing at least two strips of core material to produce a composite strip.      One or more of the strips may be run through a pressure roller structure prior to super-positioning of the strips. The one or more strips may contain internal apertures. The composite strip is coiled helically to produce the hollow cylindrical stator core. By pressure rolling at least one strip, the internal diameter of the stator core can be adjusted to reduce irregularities. By superimposing strips prior to coiling, thinner strips can be used without requiring the stator forming machine to operate longer or faster to produce stator cores of a given size, even though thinner strip material is being used. By using strips that contain internal apertures, unwanted deformations can be reduced. The pressure rolling aspects of the invention and the strips that may contain internal apertures are also applicable to coiling apparatus that uses only a single strip. Stator cores may also be made by coaxially assembling and joining two coils with a hollow annular lamination disposed between the two axially spaced coils.

Patent CA-2292516-A1 (CA)
Inventor: LARSEN MARK SIEVERT
IPC: H04B7/24
Filed: 1998-06-05
Abstract: L'invention concerne un procédé d'exploitation d'un réseau de communication constitué de nombreux postes dont chacun peut transmettre et recevoir des données permettant de passer par des postes intermédiaires pour communiquer de manière opportuniste des messages à partir de postes de départ vers des postes de déstination. Chaque poste choisit un parmi un certain nombre de canaux d'appel possibles pour transmettre des signaux sonde à d'autres postes. Les signaux sonde contiennent des données identifiant le poste en question et inclut des renseignements sur sa connectivité avec d'autres postes. D'autres postes recevant les signaux sonde y répondent directement ou indirectement, indiquant ainsi au poste sondeur et aux autres postes s'ils sont disponibles comme postes de destination ou postes intermédiaires. Le poste sondeur évalue les réponses directes ou indirectes pour identifier d'autres postes avec lesquels il peut communiquer de façon optimale. Par exemple, les postes peuvent contrôler la capacité cumulative requise pour atteindre un autre poste et ainsi déterminer un profil de puissance pour les autres postes, à charge pour ces derniers de choisir à travers le réseau un itinéraire capable d'optimiser le profil de puissance. On optimise ainsi le maniement du flot de données à travers le réseau en réduisant au maximum les interférences et les conflits entre postes.

Inventor: TREMBLAY JACQUES P
IPC: A61K31/7036
Filed: 1999-12-22
Abstract: This invention relates to a method of treating an inherited disease due to a point mutation producing a stop codon by administering an effective dose of an aminoglycoside antibiotic or a derivative thereof. Mdx mouse, which is an animal model for Duchenne muscular dystrophy, has been successfully treated with intramuscularly administered 1 and 5 mg gentamicin, which had for effect to suppress the premature stop mutation by inserting an amino acid at the stop codon. Dystrophin positive muscle fibers not different in number from those of normal mouse were detected at the dose of 5 mg gentamicin.

Title: Poudre enduite et son procede de preparation
Inventor: NAKATSUKA KATSUTO
IPC: B22F1/16
Filed: 1998-10-28
Abstract: L'invention concerne une poudre enduite hautement fonctionnelle, pouvant être préparée non pas selon un procédé comprenant l'hydrolyse d'un alcoxyde métallique, mais selon un procédé pouvant être mis en oeuvre sans utiliser un alcoxyde métallique coûteux et un solvant organique fortement inflammable, cette poudre étant ensuite distribuée grâce à une installation antidéflagrante. L'utilisation de cette poudre permet non seulement de réguler la température et l'humidité, mais aussi de faire baisser les coûts de fabrication dans leur ensemble. L'invention concerne également le procédé de préparation de cette poudre. Cette poudre enduite est composée de particules d'un substrat, chacune de ces particules étant recouverte d'un ou plusieurs films, dont au moins un est formé à partir d'un sel métallique par une réaction dans un solvant aqueux, à un pH constant. Ce procédé ne fait pas précipiter un solide à l'état libre (c'est-à-dire qui n'adhère pas à la particule) en phase liquide, et peut permettre d'obtenir un film solide uniforme sur toute la surface de chacune des particules du substrat, tout en empêchant toute agrégation de ces particules.

Inventor: BLOTT STEPHEN MICHAEL
IPC: H04L12/18
Filed: 2000-05-15
Abstract: Duplicate processing at network operators is avoided by applying once-only processing at operators which are adjacent to either the source or destination host of a data packet. An operator is adjacent to a host if there exists a path between the operator and the host containing no other operators. In one embodiment, an operator determines that it is adjacent to a host if it receives a special broadcast data packet from the host. To ensure that no other operators receive the special broadcast data packet, the adjacent operator drops the packet. In another embodiment, operators determine whether they are adjacent to identified hosts by transmitting special ping packets to the hosts. If an operator receives a ping response from the host, the operator determines that it is adjacent to the host. To ensure that only adjacent operators receive ping responses, intervening operators drop special ping packets received from other operators.

Inventor: CHANG L PATRICK
IPC: B29C44/04
Filed: 2000-12-15
Abstract: The method of the present invention is particularly suited for of making decorative objects in a mold cavity. The method enables one to form a decorative component having an outer elastomeric layer that is integral with an inner layer of foam. Because the chemical formulation for the outer layer and the inner layer is identical, other than the inner layer includes a foaming agent, the decorative component does not suffer from the drawbacks of the previous methods such as, for example, poor adhesion between the elastomeric layer and the foam layer causing delamination of the two layers; sinks or holes in the foam layer leading to imperfections in the elastomeric layer, and bleed through to the elastomeric layer from the foam layer. The method permits the mold to be pre-coated with an in-mold paint prior to the molding process. Coatings can also be applied after demolding the resulting part.
