Patent CA-2384044-A1 (CA)
Inventor: BASAVANHALLY NAGESH R
IPC: G02B6/38
Filed: 2002-04-30
Abstract: A precise fiber array is formed using a chuck to tightly hold as an array with hexagonal packing a group of precision ferrules into ones of which is inserted and, bonded a fiber end. The bonding is typically performed by gluing the fiber into the ferrule. The ferrules may also be bonded to each other. Once the ferrules are bonded together, the chuck may be removed. The terminating end of the fibers may be polished. Alternatively, cleaved terminating fiber ends may be employed, with the various terminating ends being coordinated, e.g., by as optical flat. The ferrules may have a tip and a conical entrance. The chuck may hold the ferrules in a straight orientation. The fiber terminating faces of all of the ferrules may be substantially coplanar. The ferrules may be arranged in a hexagonal configuration.
Patent CA-2389454-A1 (CA)

IPC: H01L35/34
Filed: 2000-10-25
Abstract: L'invention concerne une amélioration apportée à des films supraconducteurs contenant du mercure (Hg) et à des matériaux thermoélectriques. Ces films sont produits par recuit de films de départ contenant du thallium (par ex. Tl-1212 ou Tl-2212) dans un environnement constitué de vapeur de Hg de façon à provoquer une substitution de Tl par Hg sans altération sensible de la structure cristalline des films de départ. De préférence, un corps comprenant un substrat revêtu d'un film épitaxial contenant du Tl est recuit sous vide avec un substrat à base de Hg ; en général, le recuit s'effectue à des températures comprises entre 600 et 900 ·C pendant une période comprise entre 1 et 20 heures environ. Les films obtenus contenant du Hg présentent une valeur J¿c? d'au moins environ 10?6¿ A/cm?2¿ (100 K, OT) et une valeur X¿min? pouvant s'élever jusqu'à 50 % environ. Les matériaux thermoélectriques sont préparés par perturbation d'un précurseur cristallin de structure similaire à celle du matériau final, de façon à provoquer la libération d'une première molécule faisant partie du précurseur. Une vapeur est introduite dans le système réactionnel, pendant ou peu après l'étape de perturbation de façon à provoquer le remplacement des premières molécules dans le précurseur par des molécules qui sont présentes dans la vapeur et sont différentes des premières molécules.

Patent CA-2402036-A1 (CA)
Title: Liquid and solid particle separating device
Inventor: LAKSHMAN GURUNATHAN
IPC: B01D21/02
Filed: 2002-09-09
Abstract: A separating device is provided for separating liquid from a slurry of liquid and solid particles. The device has a settling chamber including a filter screen spanning a liquid outlet opening at the open top end of the settling chamber.  A slurry inlet, in communication with the settling chamber below the filter screen, introduces a slurry of liquid and solid particles into the settling chamber.  Liquid is urged to escape from the settling chamber upwardly through the filter screen.  The filter screen, being located at the top of the settling chamber, provides a more natural separation of the liquid from the solid particles by permitting the liquid to rise upwardly through the screen while the solid particles settle out in the settling chamber to be compacted at the bottom of the chamber for removal of the compacted solids from the bottom of the chamber.
