Patent CA-2276631-C (CA)
Title: Optical fiber connector in which an optical fiber is protected even when connection is not made
Inventor: TAKEDA JUN
IPC: G02B6/38
Filed: 1999-06-29
Granted: 2008-06-17
Abstract: In an optical fiber connector (1), an outer member (2) holds a portion of an optical fiber (4A) remote from its connecting end which is connectable to a connecting end of a counterpart optical fiber. An aligning member (3) is held by the outer member so as to be movable along the optical fiber. The aligning member carries out positioning of the connecting end of the optical fiber. The aligning member is urged by a spring (5) in a direction to project from the outer member. When connecting the optical fiber to the counterpart optical fiber, the aligning member is moved in a direction opposite to the foregoing direction against an urging force applied by the spring so that the connecting end of the optical fiber is projected from the aligning member.

Abstract: A pulley (1) consists of a pulley basic body (3) [sic] which has a cylindrical outer circumferential surface (8). Sitting on this cylindrical outer circumferential surface (8) is a tire (3), which is of sandwich-like design with regard to its radial extent.  This results in a plurality of rings (13, 14, 15) concentric to one another. The ring (13) which is furthest on the inside in the radial direction and the ring (15) which is furthest on the outside in the radial direction are in each case elastomeric rings, whereas a reinforcing ring (14) is located between them. The elastomeric outer ring (15) is harder than the elastomeric inner ring (13), so that a very abrasion-resistant surface is achieved, over which the rope runs, whereas the elastomeric inner ring (13) provides for adequate resilience. The reinforcing ring (14) is provided in order to distribute the rope load as uniformly as possible over the elastomeric inner ring (13 ).

Title: Staged settling process for removing water and solids from oil sand extraction froth
Inventor: LORENTZ JAMES
IPC: B03B13/00
Filed: 2001-06-11
Granted: 2007-10-30
Abstract: Diluent-diluted bitumen froth containing bitumen and naphtha diluent hydrocarbons, water, sand and fines, (collectively "dilfroth"), is fed into a vapor-tight gravity settler ('splitter') and temporarily retained to therein produce a bottom layer of tails comprising sand and middlings, a rag layer of discrete three-dimensional structures, each comprising hydrocarbons contained in a skin of fines, and a top layer of hydrocarbons containing small droplets of water and fines ('raw dilbit'). The flux in the splitter is less than 6 m3/h of dilfroth fed per m2 of horizontal cross-sectional rag area. The in-coming dilfroth is fed directly into the splitter middlings. Demulsifier is added to the overflow stream of raw dilbit and the mixture is subjected to prolonged settling in a vapor-tight polisher tank, to produce polished dilbit containing less than 1.0 wt. % water and 0.3 wt. % solids. The splitter underflow tails, containing less than 15 wt. % bitumen, is mixed with additional diluent to raise the diluent/bitumen ratio to 4:1 to 10:1 and is gravity settled in a vapor-tight scrubber. Scrubber overflow, mostly diluent containing residual bitumen stripped from the tails, is recycled to the splitter. In concept, the sand is first separated from the bitumen in the stripper. The substantially sand-free bitumen can then feasibly be treated with chemical demulsifier and subjected to prolonged settling in the polisher to reduce water and fines contents to low levels. Bitumen lost with the splitter tails is recovered in the scrubber using a high concentration of diluent. The scrubber overflow of bitumen and diluent is recycled to the stripper to conserve diluent.

Title: Method and arrangement to accomplish a one-way flow
Inventor: PERSSON MATS
IPC: F16K7/17
Filed: 2000-12-14
Granted: 2008-08-12
Abstract: The invention concerns a method and an arrangement to accomplish a self-acting function of one-way flow in a conduit (2) with a minimal flow resistance. A one-way valve (1), which in an unaffected position blocks the conduit (2), is of a flexible, elastic material, and is arranged with a tight fit in connection to the inner surface of the conduit (2) and is partially fixed along the inner circumference of conduit (2) by means of one or more parts having a surface with longitudinal/circumferential extension in the conduit (2). In case of pressure of a medium in one direction of the conduit (2), any flow will be blocked due to the fact that said pressure of the medium will press the non fixed parts of the one-way valve (1) against the inner surface of the conduit (2), whereby a completely tight element is formed. Reversed will the non-fixed parts of the one-way valve (1) collapse in case of pressure of the medium directed in the opposite direction, whereby a flow will be let through without any substantial resistance depending on the magnitude of the pressure.

Abstract: Cette invention concerne un procédé permettant de rajeunir un catalyseur à métaux actifs dispersés (DAM) pendant la marche d'un réacteur. Selon ce procédé, l'hydrogénation du monoxyde de carbone destiné à produire un mélange d'hydrocarbures consiste à : extraire un mélange d'hydrocarbures et une partie du catalyseur DAM ; réduire la teneur en hydrocarbures ; chauffer le mélange au- dessus du point d'ébullition d'au moins un des métaux du catalyseur DAM pour obtenir un mélange en fusion; retirer tout laitier susceptible de se former sur le mélange en fusion ; réduire la taille des particules pour former un catalyseur DAM particulaire rajeuni, lequel est retourné dans le réacteur. Comme le catalyseur DAM est un catalyseur de Raney, on ajoute un métal lixiviable au mélange hydrocarburé réduit ou au produit en fusion en conditions de non oxydation et, une fois le solide réduit en particules de petite taille, on extrait le métal lixiviable au moyen d'une substance caustique. On pourra modifier ou intensifier l'activité du DAM pendant ce processus en ajoutant des métaux promoteurs ou, avant retour au réacteur, par oxydation en suspension à basse température suivie d'une réduction à haute température, ou bien par passivation avant retour au réacteur. Le catalyseur pourra être retiré ou remplacé périodiquement ou en continu pendant la marche du réacteur.
