Patent CA-2245404-A1 (CA)
Inventor: MOKEDDEM MOHAMED
IPC: F16F15/173
Filed: 1998-08-20
Abstract: An apparatus for, and a method of, controlling the torsional damping frequency of a torsional damper using a magneto-theological fluid disposed between a relatively rotating inertia ring and a surrounding chamber. A coil is continuously wrapped around the chamber and provides at least two slip rings for conducting electricity through the coil from outside the chamber. At least two corresponding wiper contacts electrically connect said slip rings to a source of DC voltage which in turn is controlled by a controller to continuously adjust the damping torsional resistance of the magneto-theological fluid. A vibration sensor can be associated with the damper and can be signal connected to the controller to continuously adjust the magnetic field through the magneto-theological fluid to continuously adjust the torsional shear resistance of the fluid, and thereby fine tune damping of the damper.

Title: Method and system for rehome optimization
Inventor: SOFMAN LEV B
IPC: H04Q3/66
Filed: 1997-03-19
Abstract: A method and system for rehome optimization of a telecommunications network includes a Data Granulator (104) which accesses network data (102) and builds switch and Rehome Circuits Group (RCG) data into a Database (106), and a Rehome Optimizer (108) which uses data base (106) as input. Optimal network configurations are determined according to automatically derived attributes associated with granulations of elements in the network called rehome circuit groups (RCGs) which are automatically derived from the network. RCGs are definable as a rehoming set of one or more circuits in the network. Optimal network configurations satisfy specified constrains and are calculated in accordance with cost objectives. Constraints include rehoming RCGs on criteria of having a relationship with other RCGs in the network and how to treat certain RCGs in the rehome process.

Patent CA-2279017-A1 (CA)
Inventor: ISAI BASHKIM
IPC: A23L2/38
Filed: 1999-08-03
Abstract: The invention is a new drink. It is called B.I. It is a natural, non-alcoholic, non-carbonic drink. The fresh, raw materials that this drink is made from are: 1) corn flour, wheat flour, sugar, and water. When completed, it is a dense, white to yellow color liquid with a very original taste.      The recipe for the B.I. drink is:      A) To produce 120 liters of B.I. are needed 12 kg of flour (corn and wheat together but not mixed). So, 1 kg of flour produces 10 liters of B.I.      B) The quantity of the 12 kg of flour is made off 9 kg of corn flour and 3 kg of wheat flour. So, the proportion of the two kinds of flours is 3 to 1.      C) The boiling time is 2.5 hours, (two and a half hours).      D) The sugar is mixed with the flour (corn and wheat together but not mixed) in the proportion 1 to 1. However, this proportion can change creating thus a variety of B.I.s such as: 1) B.I. Classica (proportion 1- flour to 1--sugar) 2) B.I. Moderata (proportion 1- flour to 0.85--sugar) 3) B.I. Dieta (using artificial sugar)

Title: Moyenneur de signaux numeriques haute performance
Inventor: BINGHAM RUSSELL D
IPC: G01N30/86
Filed: 1998-05-29
Abstract: Moyenneur de signaux numériques permettant de calculer la moyenne de données recueillies par un détecteur analogique. Le moyenneur de signaux numériques comprend un convertisseur analogique-numérique (12) qui convertit la sortie du détecteur analogique en un signal numérique pour le traitement, un dispositif de synchronisation (20) qui génère des impulsions de synchronisation retardées pour le fonctionnement de séquencement du moyenneur de signaux numériques, un dispositif (30) de calcul de la moyenne qui permet d'ajouter et de conserver des données. Les impulsions de synchronisation retardées permettent à des données d'être acquises par le CAN (12) par une série de séquences de synchronisation à décalage variable par rapport à une impulsion de déclenchement. Le décalage des séquences de synchronisation de l'acquisition des données à l'aide de tranches de temps inférieures à la vitesse d'échantillonnage véritable du CAN (12) permet à des données d'être acquises à une plus grande vitesse d'échantillonnage effective. Une série complète de séquences de synchronisation décalée produit un ensemble de données contenant toutes les informations qui seraient acquises par un CAN ayant une vitesse d'échantillonnage plus rapide. La précision des données est encore accrue par une série de dispositifs de calcul de la moyenne disposés en parallèle qui comprennent un dispositif de traitement et plusieurs dispositifs de mémoire qui exécutent le calcul de la moyenne des données en temps réel. Un processeur de signaux numériques (98) applique sur les données moyennées un procédé de compression de données pour réduire la vitesse de transfert des données et les besoins en capacité de stockage nécessaires pour transférer les données moyennées dans un dispositif d'analyse et de stockage où elles seront conservées sur une longue période.

Patent CA-2302476-A1 (CA)
Title: Casting steel strip
Inventor: NIKOLOVSKI NIKOLCO S
IPC: B22D11/00
Filed: 2000-01-31
Abstract: In twin roll casting of steel strip, molten steel is introduced into the nip 16B between parallel casting rolls (16) to create casting pool (30) supported on casting surfaces (16A) of the rolls and the rolls are rotated to deliver solidified strip (20) downwardly from the nip. Casting surfaces (16A) are textured by a random pattern of discrete projections having pointed peaks and the strip is moved away from the casting pool at a speed of more than 60 meters per minute. In order to suppress chatter defects, the molten steel has a manganese content of less than 0.6% by weight and a silicon content in the range of 0.1 to 0.35% by weight. The random texture may be produced by grit blasting the casting surfaces on a substrate covered by a protective coating. Alternatively the texture may be produced by chemical deposition or electrodeposition of a coating onto a substrate to form the casting surfaces.
