Patent CA-2270445-C (CA)
Inventor: SCHONFELD MARK
IPC: H04Q7/34
Filed: 1997-10-14
Granted: 2006-01-31
Abstract: The invention relates to a method and device for checking if data records have been created correctly and fully in telecommunication systems. An automatic review system enables customer behaviour oriented communications to be carried out in the telecommunication system which is to be checked. Communication parameters in calling and called stations are recorded independently from each other and the network, reviewed and filed as a reference data record. Communication data records which are automatically self-recorded in the telecommunication network are subsequently verified on the basis of reference data records filed in the review system. The invention is characterized in that the system creates its own reference data records required for verification. These data records are 100 % qualitatively reviewed, real communication data. The review includes all computationally relevant parameters. Defective communication data records are analysed, including telecommunication and connection data recorded by the review system and telecommunication devices, along with signalling and review information files.

Patent CA-2277897-C (CA)
Inventor: MCGOWAN OLIVER W
IPC: B65H23/192

Granted: 2004-10-05
Abstract: L'invention concerne un système de régulation de tension qui permet d'améliorer la qualité d'un tapis par le maintien d'une tension constante le long d'un matériau de premier dossier. Le système régule la tension en maintenant la rotation d'un rouleau d'entrée à broches (16) à une vitesse légèrement inférieure à celle d'un rouleau de sortie à broches (18). Le rouleau de sortie à broches est entraîné par un moteur d'entraînement principal alors que le rouleau d'entrée à broches est entraîné de manière indépendante par un moteur d'entraînement vectoriel. Un codeur, couplé au rouleau de sortie à broches, est entraîné en synchronisme avec ledit rouleau de sortie à broches et fournit des impulsions de sortie qui sont converties en un signal analogique représentatif de la vitesse de rotation du rouleau de sortie à broches. Une valeur de tension désirée, définie par l'utilisateur, est communiquée à un contrôleur, qui surveille les signaux de sortie de deux dynamomètres afin de déterminer la valeur de la tension réelle du matériau de premier dossier. Sur la base de la différence entre la valeur de la tension réelle et la valeur de tension désirée, le contrôleur émet un signal de commande, lequel est fourni à un circuit d'entraînement. Le circuit d'entraînement entraîne le moteur vectoriel et, par conséquent, le rouleau d'entrée à broches à une vitesse qui est déterminée par le signal analogique représentatif de la vitesse de rotation du rouleau de sortie à broches et par le signal de commande émis par le contrôleur. Ce système permet d'améliorer la qualité des tapis fabriqués par la machine de touffetage puisque la densité des mailles et le motif de tapis restent sensiblement constants, les variations des motifs pouvant être ainsi réduites au minimum.

Abstract: A method for drying anhydrous paroxetine hydrochloride characterized by comprising: (A) drying anhydrous paroxetine hydrochloride, which has been obtained by reacting a paroxetine compound with hydrogen chloride in the presence of isopropyl alcohol to thereby crystallize the same, in a substantially moisture-free atmosphere at 60 °C under atmospheric pressure until the isopropyl content is reduced to 15 % by weight or less; and (B) then further drying the anhydrous paroxetine hydrochloride under reduced pressure of 20 mmHg or below at 80 to 110 °C until the isopropyl content is reduced to 5 %  by weight or less. By using this method, the isopropyl alcohol remaining in anhydrous paroxetine hydrochloride, which has been crystallized in the presence of isopropyl alcohol, can be efficiently reduced within a short time without resort to any large-scaled apparatus.

Patent CA-2309499-C (CA)
Title: Information management and retrieval
Inventor: WEEKS RICHARD
IPC: G06F17/30
Filed: 1998-11-18
Granted: 2007-06-19
Abstract: A method and apparatus is provided for extracting key terms from a data set, the method including the steps of identifying a first set of one or more word groups of one or more words that occur more than once in the data set, and removing from this first set a second set of word groups that are sub-strings of longer word groups in the first set. The remaining word groups are key terms. Each word group is weighted according to its frequency of occurrence within the data set. The weighting of any word group may be increased by the frequency of any sub-string of words occurring in the second set and then dividing each weighting by the number of words in the word group. This weighting process operates to determine the order of occurrence of the word groups. Prefixes and suffixes are also removed from each word in the data set. This produces a neutral form of each word so that the weighting values are prefix and suffix independent.

Title: Rake having grasping features
Inventor: CREVIER JOCELYN
IPC: A01D7/10
Filed: 2000-05-30
Granted: 2006-01-03
Abstract: A rake having grasping features, the rake including and elongated and tubular rake handle. A main rake head is attached to the handle and an auxiliary rake head is pivotally attached to the main rake head by an auxiliary head hinge. The auxiliary head hinge allows the auxiliary rake head to pivot relative to the main rake head between an opened and a clamping configuration in a jaw like manner. A actuating sleeve is slidably mounted on the rake handle and an actuating rod is pivotally attached between the actuating sleeve and the auxiliary rake head. Biasing sleeve is mounted on the rake handle between the actuating sleeve and the main rake head. Slidable movement of the actuating sleeve towards the main rake head resiliently compresses the biasing sleeve. When in a compressed state, the biasing sleeve have an inherent tendency to resiliently spring back towards its uncompressed state, biases the actuating sleeves away from the main head and, through the mechanical link created by the actuating rod, biases the auxiliary rake head towards the open configuration.

Title: Uplinking downsampled signals from cellular base stations to a cellular exchange
Inventor: BACKSTROM OLOF TOMAS
IPC: H04B7/06
Filed: 1999-05-14
Granted: 2007-07-10
Abstract: Cellular radiotelephone communication systems and methods downlink digital coded speech from a cellular radio exchange to a cellular radiotelephone base station and uplink downsampled (i.e. undersampled relative to the Nyquist rate of two samples per symbol) radiotelephone signals from the cellular radiotelephone base station to the cellular radio exchange. The downsampled radiotelephone signals are demodulated at the cellular radio exchange and the digital coded speech is modulated at the cellular radiotelephone base station. Diversity demodulation may be used at the cellular radio exchange, to diversity demodulate the downsampled radiotelephone signals at the cellular radio exchange. By downlinking digital coded speech from the cellular radio exchange to the cellular radiotelephone base station, and uplinking downsampled radiotelephone signals from the cellular radiotelephone base station to the cellular radio exchange, narrowband uplinks and downlinks may be provided between the base stations and the cellular radio exchange, to thereby reduce cost. Moreover, since demodulation takes place at tlu cellular radio exchange rather than at the base stations, low cost base stations may be provided.  However, since downsampled radiotelephone signals are transmitted from the base stations to the cellular radio exchange, diversity demodulation may be performed at the cellular radio exchange, to thereby improve the voice quality of the cellular radiotelephone communications.
