Patent CA-2054038-C (CA)
Title: Optical functioning glass, optical fiber, waveguide device, and optically active device
Inventor: ONISHI MASASHI
IPC: C03C4/00
Filed: 1991-10-23
Granted: 1999-04-06
Abstract: Abstract of the Disclosure An optically active device comprising an optical fiber, a light source and a coupler is disclosed.  The optical fiber has a core made of a silicate glass containing Rb and/or Cs oxide.  The core is doped with Nd3+ as an active ion and transmits light at 1.3 µm band.  The light source generates excitation light at 0.8 µm.  The coupler directs the excitation light from the light source into the core of the optical fiber.  A signal light or a spontaneous light at 1.3 µm band which is transmitted in the core stimulates Nd3+ to emit light at 1.3 µm band.  As a result an optical function such as optical amplification can be effected at 1.3 µm band.

Abstract: Le dispositif comporte un outil d'intervention constitué par exemple d'un ensemble de pompage et d'un ensemble de mesure qui sont associés à une colonne de production et descendus dans un puits.  La liaison entre l'un au moins des deux ensembles et une installation de surface est effectuée au moyen d'un câble multi-conducteurs pourvu d'un connecteur enfichable de façon différée et transporté jusqu'audit ensemble par un courant de fluide. Pour éviter les effets indésirables que peut avoir le fluide de pompage sur les instruments de mesure ou d'éventuelles impossibilités de circulation avec certains moyens de pompage, on installe sur la colonne à proximité de l'ensemble concerné ou de chacun d'eux, une vanne de dérivation permettant l'échappement du fluide à l'extérieur de la colonne. Cette vanne est par exemple une vanne coulissante, le connecteur étant pourvu de moyens pour ouvrir et fermer cette vanne dans ses translations au voisinage de sa position d'enfichage.  Application à la production d'effluents pétroliers par exemple.

Granted: 2002-07-16
Abstract: Today there is a growing demand to recycle plastics including polyethylene terephthalate.      Sources of polyethylene terephthalate for recycling often contain polyvinyl chloride. It is necessary to separate polyvinyl chloride from the polyethylene terephthalate before it can be recycled into useful products. This invention reveals a process for recovering polyethylene terephthalate flakes from a recycle stream containing polyethylene terephthalate flakes and polyvinyl chloride flakes which comprises: (1) treating the recycle stream with (a) at least one inorganic base selected from the group consisting of sodium hydroxide and potassium hydroxide and (b) at least one nonionic surfactant under conditions and for a time sufficient to decrease the contact angle of the polyethylene terephthalate flakes with water below a value of 25° while maintaining the contact angle of the polyvinyl chloride flakes above a value of about 45°; (2) adding the treated recycle stream to water, to form an aqueous mixture containing the treated polyethylene terephthalate flakes and treated polyvinyl chloride flakes; (3) agitating the aqueous mixture to allow the polyvinyl chloride flakes to come in contact with gas bubbles; (4) allowing the polyvinyl chloride flakes to float to the surface of the aqueous mixture and allowing the polyethylene terephthalate flakes to sink to the bottom of the aqueous mixture; and (5) removing the polyvinyl chloride flakes from the surface of the aqueous mixture and removing the polyethylene terephthalate flakes from the bottom of the aqueous mixture.

Abstract: A rotary controlled motion transmission assembly is mounted behind the dashboard of a vehicle and has a knob that extends through the dashboard for rotary actuation by an occupant of the vehicle to move a bulkhead door for controlling the environment within the vehicle. The knob is connected to a cam plate having first and second ramps which rotate upon rotation of the knob. A pair of spring biased plungers, each having a camming surface, operatively engage respective ramps. A pair of cables are connected to the plungers and extend along a circuitous path within flexible conduits to a receiver assembly, such that axial translation of the plungers upon rotation of the control knob, results in axial translation of the cables. The cables are connected to a pulley mounted on a shaft which is connected to the bulkhead door for opening and closing of the door. When the knob is turned, the ramp surfaces move the plungers in opposing directions whereby the cables are moved in opposing directions thereby rotating the pulley within the receiver assembly, to move the bulkhead door.

Granted: 2004-12-07
Abstract: A gas-tube arrester includes an arrester body in which an inert gas is contained, and first and second electrodes face each other separated by an insulator. An insulating, heat-resistant film is in contact with the first electrode and has a plurality of small holes. A low-melting point metal plate layered on the insulating film has a melting point lower than a decomposition or softening temperature of the insulating film. A conductive leaf spring electrically connected to the second electrode presses the low-melting point metal plate toward the insulating film, so that, when a high voltage is applied between the first and second electrodes, an electrical discharge occurs between the first and second electrodes through the small holes of the insulating films. The leaf spring has an extend portion bent toward the first electrode, so that, if the low-melting point metal plate is melted by heat from the arrester body, the melted metal will electrically connect the extended portion of the leaf spring to the first electrode.

Abstract: A tri-dimensional non-woven fabric particularly well-suited for use as a skin-contacting cover layer of a sanitary absorbent product such as a sanitary napkin, a diaper, a urinary pad, an adult brief, a wound dressing, or a nursing pad, among others.  The non-woven fabric is characterized by a pattern of elongated and alternating high and low fiber density areas.  Such structure has the ability of  directing a discharge  of  body exudate to disperse over the surface of the non-woven fabric in a preferential direction.  The non-woven fabric also has the ability of dynamically inducing body exudate to migrate through the low fiber density areas when the fibrous network  is  subjected to repeated bending or twisting movements.   The invention also extends to a method for manufacturing the aforesaid non-woven fabric and to a sanitary article utilizing same.   The invention further extends to a sanitary absorbent article utilizing a novel skin-contacting  cover  layer  capable  to  establish  and maintain an  intimate  liquid-communicative relationship with an absorbent core of the sanitary absorbent article without any adhesive.
