Patent CA-2254336-C (CA)

Abstract: An electro-hydraulic valve actuator comprising an actuator casing; a piston/rack means in the casing having walls reciprocating linearly to effect linear movements, the reciprocating walls defining a center chamber therebetween and two outside chambers inside the casing; an output shaft in communication with the piston/rack means for driving a valve, the output shaft effecting rotational movements in response to the linear movements of the piston/rack means; resilient return means in each of the two outside chambers engaging the reciprocating walls of the piston/rack means and inner end walls of the casing, the resilient return means biasing the walls of the piston/rack means to a closed position; a pumping means; a primary internal flow path for transferring hydraulic fluid from the pumping means to a first output port and into the center chamber, the hydraulic fluid in the center chamber causing the piston/rack means to expand in the casing to transmit the linear movements to the output shaft; and a fail-safe solenoid valve system having a secondary internal flow path connecting to and extending from the primary internal flow path to a second outlet port opening into at least one of the outside chambers, and a normally closed solenoid valve in the secondary flow path preventing flow through the secondary internal flow path. Upon loss of power to the actuator, the fail-safe solenoid valve opens to thereby cause the resilient return means to force hydraulic fluid out of the center chamber, through the primary and secondary internal flow paths, into at least one of the outside chambers, so that the piston/rack means is returned to a closed position for rotating the output shaft to drive the valve.

Title: Method and apparatus for providing high speed data communications in a cellular environment
Inventor: ZEHAVI EPHRAIM
IPC: H04J13/00
Filed: 1997-10-27
Granted: 2010-02-02
Abstract: A method and apparatus for transmitting digital data in a cellular environment. Adjacent cells of the cellular system (1 and 2A-2F) are prevented from simultaneously transmitting data. Because the noise from transmission of adjacent cells is a primary source of interference, the transmission rate of power limited base stations (1-3) can be dramatically increased when the noise from adjacent cells is eliminated. The transmissions to each subscriber station (6) are made at a fixed transmission power level. However, the data rate of transmitted signals differs from one subscriber station (6) to another depending the path loss differences. In a first exemplary embodiment, the data rate of transmissions to a subscriber station (6) is determined by selecting an encoding rate for the transmitted signal while holding the symbol rate constant. In a second exemplary embodiment, the data rate of transmission to a subscriber station (6) is determined by selecting a modulation format for the transmitted signal which directly changes the symbol rate of transmission to a subscriber station (6).

Title: Heavy oils with improved properties and an additive for the same
Inventor: FEUSTEL MICHAEL
IPC: E21B37/06
Filed: 1997-10-21
Granted: 2006-10-31
Abstract: The additive described consists essentially of a selected oxalkylated fatty amine or fatty amine derivative and a special mineral salt compound, preferably a metal soap. Said additive for heavy oils produces goo d emulsification and dispersion of asphaltenes and other high molecular compounds thereby resulting inter alia in increased storage stability, improved pumpability due to reduced viscosity of the oil and longer operational life of the filter systems. Further, said additive produces better combustion of heavy oils. The effective additive quantity for said oils amounts to 2 to 2,000 ppm. The oils described are specially adequate to be used as fuel for industrial installations and power stations and as fuel for boat motors.

Abstract: A faucet diverter to be mounted within a portion of a water faucet assembly for controlling water flow to either a faucet spout or a spray discharge includes a body, a chamber within the body, and a water inlet opening into the chamber. There is a spout outlet and a spray outlet connected to the chamber and there is an orifice in the body between the chamber and the spout outlet. A poppet is movable within the body chamber and carries a cone seal adjacent one end to control flow through the orifice to the spout outlet. There is a cup seal carried by the other end of the poppet to control flow to the spray outlet. The cup seal has an outwardly-extending lip formed and adapted to be in contact with a wall of the chamber and the cup seal has a generally annularly disposed recess at the end away from the lip. There are a plurality of outwardly extending projections on the exterior of the cup seal, bearing against the chamber wall, and being located generally in alignment with the recess. The cup seal is formed of an elastomeric material which distorts under pressure from water within the chamber, with the result that water pressure in the recess causes distortion of the cup seal toward the chamber wall between the cup seal projections.

Abstract: L'invention traite d'un procédé permettant d'isoler, à partir de banques d'ADN et grâce des protéines de fixation de l'ADN, des séquences nucléotidiques codant des peptides cibles et ce, dans le but de fixer le peptide à la séquence qui le code. Des banques d'ADN sont préparées à partir de cellules codant la protéine donnée, ou à partir d'ADN synthétique, et introduites dans, ou à proximité, d'une protéine de fixation de l'ADN d'un vecteur d'expression aux fins de créer une protéine hybride chimère. L'incorporation de cet ADN vecteur dans un module porteur au cours de l'expression de ladite protéine hybride chimère provoque la production d'un PDCP (module porteur de peptides) présentant la protéine hybride fixée à l'ADN sur la surface externe du module porteur. Grâce aux techniques de purification par affinité, les particules du PDCP renferment des séquences codant le peptide souhaité devant être sélectionné et les séquences nucléotidiques souhaitées obtenues grâce à ces techniques.

Title: Card activation at point of distribution
Inventor: DAVIS VIRGIL M
IPC: G07F7/10
Filed: 1998-12-18
Granted: 2008-04-29
Abstract: Secure activation of stored value cards (30) at a point of distribution uses a portable activation secure application module (ASAM) (208) within the card dispensing machine (24) to activate each card. Each card has a standard user mode and a security user mode. In the standard user mode the card is activated and ready for use. In the security user mode the card is not active and cannot be used to make a purchase. An issuer (20) supplies an issuer activation key (40) to a card supplier (22) who produces a security code (72) which is stored on a stored value card (30). Cards are supplied to the issuer (20) in security user mode, and stored in a dispensing machine (24).  The issuer activation key (40) is also relayed to the dispensing machine and stored on the ASAM (208). Upon purchase by a customer (26), the issuer activation key (40) is used within the machine (24) by the ASAM (208) to reproduce the security code (72) and to activate a card. An activation control counter (ACC) is stored within the ASAM and is decremented for every attempt at activation of a card. ASAMs are maintained in the field using a dial-up connection to a central computer (202) with a control secure application module (CSAM) (206), or using a field secure application module (FSAM) (502) that is created at a central location using the CSAM (206). Each FSAM is able to update a limited number of ASAMs. A hierarchy of keys (600) is used by the CSAM, the FSAMs and ASAMs to ensure security.

Title: Synthesis-based pre-selection of suitable units for concatenative speech
Inventor: CONKIE ALISTAIR D
IPC: G10L13/00
Filed: 2001-06-28
Granted: 2007-07-24
Abstract: A method and system for providing concatenative speech uses a speech synthesis input to populate a triphone-indexed database that is later used for searching and retrieval to create a phoneme string acceptable for a text-to-speech operation. Prior to initiating the "real lime" synthesis, a database is created of all possible triphone contexts by inputting a continuous stream of speech. The speech data is then analyzed to identify all possible triphone sequences in the stream, and the various units chosen for each context. During a later text-to-speech operation, the triphone contexts in the text are identified and the triphone-indexed phonemes in the database are searched to retrieve the best-matched candidates.
