Title: Sensing arrangement for sensing the addition of reactants to a solution
Inventor: CHAN WAI YIN CEDRIC
IPC: G05D11/13
Filed: 1997-04-08
Granted: 2006-06-13
Abstract: A sensing arrangement for sensing the addition of reactants to a solution (1 2) within a tank (14) which includes a first inlet (16), a second inlet (18), and a reactant supply controller (28) for controlling the addition of reactant into the tank through the first and second inlets. The first inlet is configured to supply a first reactant (20) to the tank and the second inlet is configured to supply a second reactant (24) to the tank. The sensing arrangement comprises a detector (34), such as a conductivity detector or an ion concentration detector, having a probe (36) for measuring the presence of the reactants in the solution within the tank. The probe (36) is positioned substantially adjacent to the second inlet (18). The detector provides a mechanism for measuring the presence of and concentration of the first reactant in the solution while the first reactant is added to and mixed with the solution. The detector (34) also provides a mechanism for measuring the presence of the second reactant (24) in a portion of the solution (12) substantially adjacent the second inlet (18) as the second reactant is being added to the solution thereby detecting the influx of the second reactant as it is introduced into the tank (14).

Patent CA-2258522-C (CA)
Inventor: SVENSSON ANDERS
IPC: B23D57/02
Filed: 1997-06-17
Granted: 2005-03-29
Abstract: A motor saw for cutting wood or stone includes a continuous wire loop (18) which carries uniformly-spaced cutting elements (25) and which is tensioned over a saw blade (17), from a drive wheel (30) mounted in the machine housing (15) to a loop-guiding sprocket wheel (20) at the outer end of the saw blade (17), said sprocket wheel functioning as a circular saw.      As the cutting elements (25) pass over the sprocket wheel (20), they drop into recesses (28) between cog-like sprockets (27) thereon.      The sprockets (27) support and guide the wire loop with the cutting elements (25) hanging freely in cutting positions in the recesses (28) between the sprockets. In the case of a duplicated wire loop, a cog cam (51) on the sprockets penetrates between parts (18', 18") of the loop so as to prevent the freely-hanging cutting elements (25) from twisting. These cutting elements may be irregularly shaped if desired. Given an enlarged diameter, the guide sprocket wheel (20') with the aid of the saw blade (17) attains an enhanced circular-saw effect to a depth that passes beyond the centre of the guide sprocket wheel (20').

Title: Font sharing system and method, and recording medium storing program for executing font sharing method
Inventor: TESHIMA ATSUSHI
IPC: G09G5/24
Filed: 1999-03-30
Granted: 2009-09-29
Abstract: A client computer and a server share fonts in an efficient manner. The client computer and server are capable of communicating data with each other. Character specifying data for specifying a character and a font ID for specifying the font of this character are stored in a layout information file and transmitted from the client computer to the server. On the basis of a layout information file, the server retrieves character image data (a bitmap text file) expressing the character as an image. The server transmits the found character image data to the client computer. When character image data cannot be found, the character image data is generated and is then transmitted from the server to the client computer.

Title: Optical cross-connect restoration technique
Inventor: AFFERTON THOMAS S
IPC: H04B10/275
Filed: 1999-04-07
Granted: 2003-01-07
Abstract: An alarm and restoration system (28) accomplishes restoration in a ring network (10 1) by monitoring network traffic to detect the occurrence of a single failure arising from a failed optical service path (14i) and the occurrence of a double failure arising from a failed optical service path and an occupied optical protection path (16i). In case of a single failure, the alarm and restoration system (28) restores traffic in the network itself by routing traffic on a restoration path. In the event of a double failure, the alarm and restoration system (28) routes traffic from the failed ring network through an Optical Cross-Connect mesh (22) to transform the double failure into a single failure that can be restored in the network itself.

Title: Self-blunting needle medical devices and methods of manufacture thereof
Inventor: JONES ALEXANDER K
IPC: A61M5/32
Filed: 1997-12-15
Granted: 2006-10-10
Abstract: A self-blunting needle medical device comprises a needle cannula (18) fixed to a hub (20) having a receiving structure therein such as ferrule (22) and a movable blunting member (14) movably received within the cannula (l8). Ferrule (22) defines a sleeve bore (38) extending therethrough, within which both the cannula (18) and the movable member (14) can be received and which establishes a coaxial relationship between them. The ferrule (22) defines a first guide surface (40) for directing the blunting end (14a) of the movable member (14) into the central bore of the cannula (18) during assembly. A second guide surface (42) performs the function of guiding the proximal end (18b) of the cannula (18) into ferrule (22) for mounting therein.  Typically, the cannula (18) has a tissue puncture tip (18a). When the movable member (14) is retracted into the cannula (18), the puncture tip (18a) is exposed for use, e.g., injection into tissue. The movable member (14) is then moved to an extended position in which blunting end (14a) projects beyond the puncture tip (18a), to render the device safe with regard to subsequent accidental needle sticks.

Abstract: L'invention concerne un récepteur dynamique programmable, permettant d'obtenir le niveau de performance voulu pour une consommation d'énergie réduite. Le convertisseur analogique-numérique (ADC)  SIGMA  DELTA  situé à l'intérieur de ce récepteur comprend une ou plusieurs boucles, chacune de ces boucles permettant d'obtenir une performance dynamique prédéterminée. Ces boucles peuvent être validées ou invalidées en fonction de la dynamique voulue et des seuils de cette dynamique. Le convertisseur ADC  SIGMA  DELTA  est par ailleurs conçu pour fonctionner avec un courant de polarisation réglable, la dynamique de ce convertisseur ADC  SIGMA  DELTA  variant approximativement selon ce courant de polarisation. En régulant ce courant, on peut obtenir grâce audit convertisseur ADC  SIGMA  DELTA  la dynamique voulue pour une consommation d'énergie minimale. La tension de référence de ce convertisseur ADC  SIGMA  DELTA  peut en outre être réduite si la dynamique voulue n'est pas élevée, ce qui ne requiert qu'un faible courant de polarisation pour ce convertisseur ADC  SIGMA  DELTA  ainsi que pour les circuits auxiliaires. La dynamique de ce convertisseur ADC  SIGMA  DELTA  constitue également une fonction du rapport de suréchantillonnage, lequel est proportionnel à la cadence d'échantillonnage. Une dynamique élevée nécessite donc un rapport d'échantillonnage important, mais si une dynamique élevée n'est pas indispensable, la fréquence d'échantillonnage peut être réduite.

Abstract: An anti-backlash mechanism is described in the form of a pair of nuts (14, 16) or nut halves with internal threads complementary to the threads on a lead screw (10). The mechanism is translated by rotation of the screw. One of the nuts (14) has an outer cantilevered wall (31A) with inner gear teeth (30A) which engage outer gear teeth (30B) on the other nut. Rotation of one nut with respect of the other nut tightens or loosens an abutting frictional rotation-opposing resistance of an elastomeric washer (52) compressed between the two nuts. The compressed washer exerts a bias force against the nuts opposing axial forces exerted by the lead screw against the flanks of the nut threads.
