Patent CA-2219498-A1 (CA)
Inventor: CHALMERS HARVEY
IPC: H04B1/7085
Filed: 1996-06-07
Abstract: Technique numérique de désétalement et d'abaissement de fréquence utile pour les récepteurs de communications à spectre étalé, qui suit une phase de cadencement d'une séquence de pseudo-bruit sans pilotage nécessaire d'une horloge externe de matériel. L'utilisation d'un filtre de réception (408) adapté à la séquence d'éléments de transmission à bande réduite avant le désétalement qui réduit la quantité de bruit présente après le désétalement constitue un avantage supplémentaire de ladite technique. Une filtre à bande étroite (404) permet également l'utilisation d'un seul convertisseur A/N (406) dans le récepteur et l'échantillonnage FI à un taux d'échantillonnage relativement bas comparé à d'autres techniques. Un procédé permettant de réduire un nombre total de calculs requis, qui facilite donc l'application dans un seul circuit intégré numérique personnalisé, est également décrit. La technique de la présente invention peut aussi être appliquée aux applications multivoie. Un procédé et un appareil destinés aux applications multivoie sont encore décrits.

Title: Air ring for cooling blown plastic film
Inventor: DANG NGHIA C
IPC: B29C48/10
Filed: 1997-11-04
Abstract: An air ring for supplying cooling air to a hot extruded plastic film after the film has been extruded from an annular extrusion die at an elevated temperature has an annular body which surrounds the tubular film after the film has left the extrusion die. The body has a circumferentially extending air passa ge through which air can be supplied from an external source and which directs cooling air from the passage between the body and the film with a venturi-like effect. A circumferentially extending series of individually operable actuators are each operable to vary the venturi-like effect at its circumferential location an d cause the film to become nearer to or further from the body at said location to cause the thickness of the film at said location to decrease or increase.

Title: A bladed rotor and surround assembly
Inventor: MORRIS STEVEN BARNEY
IPC: F01D9/04
Filed: 1997-11-06
Abstract: A bladed rotor and surround assembly comprising an annular casing (18), a bladed rotor element (8b) that is rotatable about an axis (3) concentrically within the casing (18), and an annular shroud liner. The shroud liner, typically made up of an annular array of circumferentially abutting shroud liner segments (32), is disposed within the casing (18) in an annular radial space (31) defined between the casing (18) and an outer circumference of the bladed rotor (8b) . The shroud liner segments (32) have location means (40,46) to locate each segment (32) within the casing (18) . The location means (40,46) and the annular radial space (31) are configured to enable axial insertion of the shroud liner segment (32) between the bladed rotor (8b) and the casing (18). In addition the location means (40,46) and the annular radial space (31) allow a limited amount of radial translation of the shroud segment (32) during insertion. The location means (40,46) also provide a positive radial location to prevent radial translation of the shroud segment (32) once each shroud segment (32) is in a final assembled position.

Abstract: Procédé de traitement cutané permettant d'éliminer les cellules superficielles (12) de l'épiderme, de réduire ou d'éliminer les poils (28) indésirables et de soulager les troubles cutanés tels que l'acné et la séborrhée. Un produit contaminant (4) présentant une forte absorption à une longueur d'onde de la lumière est appliqué localement sur une zone de la peau. Un produit contaminant préféré est constitué d'un mélange à 20 % de particules de graphite d'un micron dans de l'huile minérale. Des parties du produit contaminant sont poussées à s'introduire dans les espaces séparant les cellules superficielles de l'épiderme, dans les canaux pileux dans la peau et/ou dans des glandes sébacées adjacentes. Ladite zone de peau est soumise à des impulsions laser à une longueur d'onde appropriée de manière à conférer suffisamment d'énergie au produit contaminant pour qu'il provoque l'explosion des particules qu'il contient. L'énergie libérée par les explosions détache des couches de cellules mortes de la peau et/ou détruit les tissus responsables de la croissance pileuse et/ou de la production de sébum.

Title: Synchronisation in digital communications networks
Inventor: QUAYLE JOHN ALAN
IPC: H04L7/00
Filed: 1996-06-27
Abstract: In a digital communications network comprising a branched passive optical network (11, 13) connecting a head-end (15) with a plurality of optical network units (15), the time taken to synchronise, by ranging, all optical network units (15) and the head-end (10), when the network needs to be initialised from scratch, is minimised. This is achieved by making all bandwidth in the upstream direction of the network (14) available for the purpose of course ranging. Once the whole network is ranged, then bandwidth is made available, in the normal way, to combined data communications and operations and management functions.

An interface module includes a housing, serial transceiver circuitry disposed in the housing, a first input/output connector which connects to an input/output port of the portable IC card reader, a cable coupling the connector to the transceiver circuitry, and a second input/output port which couples the serial interface module transceiver to an external device. A method of operating the portable IC card reading device includes reading a stored value from an IC card when the IC card is inserted in the device, receiving user input corresponding to an amount of a planned purchase, and automatically calculating and displaying an expected balance after the planned purchase. Further, after making the planned purchase with the IC card, a stored value from the IC card is read when the IC card is inserted in the device, and the value read is displayed.

IPC: F02D9/10
Filed: 1998-02-23
Abstract: [Problems to be Solved] To provide a carburetor for a two-cycle engine, and prevent water from entering into the engine, using a lubricating system of the engine. [Means to Solve the Problems]    Oil sealing members 98 are attached to bearings of a throttle shaft 80 of a carburetor 36. Oil holes 95 are formed at positions near a barrel passage 82 and inside the oil sealing members 98, thereby forcibly supplying lubricating oil to the bearings. Therefore, the bearing are continuously lubricate, so that water is prevented from entering into the carburetor. The forcibly supplied lubricating oil leaks from the bearings to the barrel passage 82, and is supplied to the interior of the engine together with air-fuel mixture produced by the carburetor 36. The two oil holes 95 communicate with each other via a dovetail groove 96, so that the lubricating oil from a lubricating oil plug 97 is simultaneously supplied to the bearings at the opposite ends of the throttle shaft.
