Patent CA-2297874-A1 (CA)
Inventor: STRATICO GIANFRANCO
IPC: H02K15/09
Filed: 2000-02-03
Abstract: The present invention discloses methods and apparatus for winding successive differently sized components with coils of wire. More specifically, the present invention is directed to methods and apparatus for winding multiple electric motor armatures in succession, when those armatures have different dimensions. Generally speaking, the invention includes an assembly with movable parts, which enables all armatures to have a common alignment characteristic in the winding apparatus. If necessary, the actual coil winding mechanism will shift to achieve proper positioning relative to each armature. This reduces the number of adjustments that have to be made to hardware that is ordinarily required to wind such differently sized armatures.

Patent CA-2300293-A1 (CA)
Inventor: UGLENE WENDELL VAUGHN
IPC: A41D13/005
Filed: 2000-03-07
Abstract: An enhanced personal cooling garment has an inner layer and outer layer that define a confined space or bladder therebetween for containing liquid water. The inner and outer layer are thin materials that are impermeable to both air and liquid water yet permeable to water vapour. The garment is worn in a manner such that the innermost layer is in direct contact with the wearer's skin. The liquid water between the layers diffuses as vapour through the outer layer; it removes latent heat required for evaporation hence provides cooling to the human body. As both layers of the garment are permeable to water vapour, sweat produced by the wearer can diffuse through the innermost layer, where it will then condense into liquid. When worn beneath an air-cooling garment that distributes cool; dry air over the body, the rate of evaporation increases, resulting in even greater enhancement of cooling of the wearer.

Patent CA-2309738-A1 (CA)
Inventor: ROGERS DUNCAN
IPC: G03F1/00
Filed: 1998-11-06
Abstract: L'invention concerne un procédé de tracé de motifs sans masque sur les surfaces de solides réactifs à l'échelle moléculaire ou atomique. Un motif à l'échelle moléculaire de molécules d'adsorbat est utilisé à la place d'un masque macroscopique classique. Les molécules sont adsorbées pour former des motifs sur une surface, ceci en fonction de la structure de cette surface, de la nature chimique de l'adsorbat et de la couverture d'adsorbat sur la surface. La surface est tracée, puis marquée ou gravée avec le motif par déclenchement d'une réaction chimique localisée entre les molécules d'adsorbat et la surface du solide, ce qui permet d'obtenir une impression à proximité des molécules d'adsorbat. Selon l'un des aspects de l'invention, une réaction photo-induite ou électro-induite de l'adsorbat tracé déclenche une réaction entre le motif et la surface. Cette réaction peut se concrétiser sous la forme d'une fixation du motif sur la surface ("écriture" ou "dopage" selon le motif) ou retrait selon ce motif des atomes de la surface ("gravage" intervenant pendant la réaction initiale ou par irradiation subséquente de la surface tracée). Lorsqu'il est irradié par des photons, des électrons ou des ions, l'adsorbat grave un motif sur le substrat par réaction localisée. Ce nouveau procédé peut être illustré par le cas d'un substrat de silicium et de molécules de chlorobenzène qui, dans un premier temps, sont adsorbées sous forme d'un motif sur un cristal de silicium et qui, en cas d'irradiation par des photons ou des électrons, chlorure le cristal selon un motif semblable à celui de l'adsorbat. La façon la plus directe de démontrer la présence d'une réaction chimique localisée consiste à induire une réaction dans une zone restreinte et à montrer que cette réaction provoquée par irradiation se produit essentiellement dans cette même zone. Ce procédé convient pour écrire, doper ou graver des détails à l'échelle moléculaire.

Abstract: L'invention concerne un système permettant d'appliquer une suspension dans l'eau de particules d'amidon non cuites, sur une feuille continue se trouvant sur une toile de formation (14), au moyen d'une buse (25) d'applicateur placée en travers de la feuille continue. Ce système comprend un collecteur intérieur débouchant sur une fente de buse s'ouvrant vers le bas, à travers laquelle la matière provenant du collecteur s'écoule sur la feuille continue sous la forme d'un rideau tombant (30). La buse comporte plusieurs entrées espacées dans le sens transversal, conduisant au collecteur de façon à définir des zones d'application espacées dans le sens transversal. L'amidon en suspension et l'eau de dilution sont amenés du collecteur jusque dans les entrées, en passant par des valves de régulation (36, 38), ce qui permet de faire varier la concentration d'amidon le long de la feuille continue pour conférer à cette feuille continue séchée un profil de résistance voulu, en fonction d'une caractéristique de résistance voulue, mesurée dans la partie humide.
