Title: Process and coating composition for coating a paper web
Inventor: HIETANEN SOILI
IPC: D21H25/14
Filed: 2001-01-29
Abstract: The invention relates to a process for producing a coated paper web. According to the process, a paper web is formed from a fibrous raw material in a paper machine, the paper web is coated with a pigment-containing coating mix, and the coated paper web is calendered. According to the invention, the paper web is coated with a coating composition that contains as the mineral pigment mainly a mixture of gypsum and calcium carbonate, the amount of gypsum being at minimum 10 % by weight of the total amount of gypsum and calcium carbonate. With mixtures of calcium carbonate and gypsum, such as mixtures of PCC and gypsum and mixtures of PCC, ground carbonate and gypsum, there are obtained simultaneously a sufficient gloss and smoothness as well as brightness and opacity better than with PCC-kaolin pastes.

Patent CA-2401201-A1 (CA)
Inventor: MALITEARE JASON TODD
IPC: A01M7/00
Filed: 2002-09-04
Abstract: A hydraulic actuator is provided for controlling relative movement between first and second structures between which the actuator is mounted, for example between a boom and the base frame of an agricultural sprayer, while providing some resilience in the form of suspension. The actuator comprises a piston cylinder having a floating cushion piston supported within the cylinder end to support the piston within the cylinder in a retracted position at a prescribed spacing from the cylinder end. The piston can thus be deflected from the retracted position in either direction using a pressure relief mechanism so as to provide some flexibility to the actuator to accommodate the varying forces between the pair of relatively movable structures between which the actuator is mounted. The cushion piston requires no additional electrical switches or controllers and can be part of the hydraulic circuitry of the actuator so as to provide a simple, low cost actuator with integral suspension.

Title: Systeme de controle chronique du rendement des pompes sanguines rotodynamiques
Inventor: MEDVEDEV ALEXANDER
IPC: A61M1/12
Filed: 2001-03-19
Abstract: Dans un dispositif d'assistance ventriculaire gauche, une pompe sanguine rotodynamique (10) est animée par un moteur courant continu sans balais (12). Une alimentation électrique (14) fournit la puissance au moteur (12). Trois canaux de rétroaction (tension, intensité, vitesse moteur) aboutissent à un contrôleur microprogrammé ou à un microprocesseur (18). Les trois signaux sont analysés de façon à calculer la puissance fournie au moteur, le rythme cardiaque du sujet, le débit courant de la pompe, et la pression systémique. Le microprocesseur (18) calcule ensuite un débit souhaité en fonction du rythme cardiaque du sujet. Le microprocesseur communique une nouvelle sortie de puissance à un circuit de commutation (16), ce qui régule la puissance fournie au moteur (12). La pompe (10) comporte également des contrôles de sécurité qui ont priorité sur le débit de pompe souhaité. Ces contrôles portent sur l'aspiration ventriculaire, la faible pulsatilité, les vitesses maxi et mini de la pompe, le débit de pompe rapporté à la vitesse mini, le mini absolu du débit de la pompe, les mini et maxi de la puissance d'entrée du moteur.

Abstract: This invention provides a method for controlling production operations using fiber optic devices. An optical fiber carrying fiber-optic sensor is deployed downhole to provide information about downhole conditions. Parameters related to the chemicals being used for surface treatments are measured in real time and on- line, and these measured parameters are used to control the dosage of chemicals into the surface treatment system. The information is also used to control downhole devices that may be a packer, choke, sliding sleeve, perforating device, flow control valve, completion device, an anchor or any other device. Provision is also made for control of secondary recovery operations on-line using the downhole sensors to monitor the reservoir conditions. The present invention also provides a method of generating motive power in a wellbore utilizing optical energy. This can be done directly or indirectly, e.g., by first producing electrical energy that is then converted to another form of energy.

Title: Pollen polymix plant breeding method utilizing molecular pedigree analysis
Inventor: LAMBETH CLEMENTS C
IPC: A01H1/04
Filed: 2001-07-12
Abstract: The present invention is directed to a plant breeding and testing method that utilizes a pollen mixture derived from many male parents in conjunction with field trials and molecular pedigree analysis to evaluate breeding values and make progeny selections for the next generation of breeding. More specifically the plant breeding method involves mixing pollen obtained from a breeding group composed of a plurality of parental plant to obtain a pollen polymix.  The polymix is used to pollinate female reproductive structures from parental plants in the breeding group to obtain a plurality of progeny seed lots. Each progeny seed lot has seeds obtained from a different cross between the pollen polymix and a different parental plant. Resultant progeny plants from each seed lot are evaluated using objective criteria to obtain a phenotype score.  The pedigree of a least some of the progeny plants, usually those with a desirable phenotype score, is determined using molecular parental analysis.  Lastly, the pedigree and phenotype score are used to identify elite plants for use in a next generation of plant breeding.

Title: Method for routing ad-hoc signals
Inventor: SENDROWICZ GERRY
IPC: H04L12/56
Filed: 2003-02-25
Abstract: An ad-hoc network is a typically a dynamic collection of nodes capable of communicating therebetween without the aid of pre-established infrastructure.  Ad-hoc networks differ from traditional networks in that the topology of interconnections between nodes is inherently dynamic and not fixed. Generally, the routing protocols belong to two groups: proactive and reactive. Proactive protocols attempt to maintain correct and up-to-date routing information at every node. Reactive protocols, in turn, collect necessary routing information only if a pair of nodes are to establish a communication. In accordance with embodiments of the invention a reactive ad-hoc network protocol is disclosed that uses controlled flooding to broadcast packets of information within the ad-hoc network. Furthermore, the ad-hoc network protocol does not maintain up-to-date routing information at every node in an ad-hoc network and does not utilize specific control messages to assure that packets within the ad-hoc network follow optimal paths.

Abstract: Disclosed is a circuit breaker for detecting overload. The circuit breaker detects overload electrically without using bimetal. The circuit breaker for detecting overload includes an arc fault detector and a discharge controller.  If arc fault occurs, the discharge controller discharges voltage charged in a capacitor. Therefore, the circuit breaker does not trip circuit when arc fault occurs although high current flows on a conductor. Further, the circuit breaker for detecting overload includes a charging time constant controller so that charging time is varied according to current flowing on the conductor.
