Patent CA-2273232-A1 (CA)
Title: Network operator controlled usage of long distance carriers
Inventor: PALVIAINEN KEIJO
IPC: H04W4/16
Filed: 1997-12-02
Abstract: In order to enable an operator to control the subscriber's long distance carrier usage in a telecommunications network, a new subscriber-specific parameter, a locking parameter, is added to the subscriber data by the operator, in addition to a preferred long distance carrier access code. The locking parameter defines whether said subscriber is allowed to select the long distance carrier for the call or not. The locking parameter is checked each time the subscriber dials the long distance carrier access code during an originating call setup. In an embodiment of the invention, if the locking parameter indicates the subscriber is not allowed to select the long distance carrier, the call setup will be always terminated, preferably after making an announcement for informing the subscriber of the cause of the termination.

Patent CA-2284214-A1 (CA)
Title: System and method for automatically maintaining a computer system
Inventor: ISENBERG HENRI J
IPC: G06F11/25
Filed: 1998-02-04
Abstract: A system and method for the automated maintenance of a computer system. A  scheduler periodically activates sensors. When activated, the sensors gather information about various aspects of the computer system. The sensors store this information in a knowledge database. The knowledge database also contains cases, questions, and actions. The cases describe potential computer problems and solutions. The questions are used to diagnose the problems, while the actions describe steps that can be taken to solve the diagnosed problems. If the information gathered by the sensors indicates a problem with the computer system, then the sensors activate an artificial intelligence engine. The engine uses the information in the knowledge database to evaluate certain cases. If information necessary to evaluate a case is not in the knowledge database, then the engine activates a sensor to gather the information. As the cases are evaluated, the confidence levels of certain other cases, questions, and actions increase. If the confidence level of a case or question rises above a predetermined threshold, then the engine evaluates that case or question. If the confidence level of an action rises above the threshold, then that action represents the likely solution to the problem. Accordingly, the engine activates a sensor to perform the action. If no case, question, or action rises above the threshold, then the knowledge database does not contain enough information to solve the problem. In such a case, the engine saves the state of the computer system and knowledge database. Then, a human expert can update the database with the knowledge necessary to solve the problem.

Patent CA-2286599-A1 (CA)
Inventor: AHMED ZAHEER
IPC: H04L12/70
Filed: 1998-04-14
Abstract: A network interface for mapping local ethernet traffic onto an ATM-based broadband access network includes an adaptive MAC-level bridge that employs a fast algorithm for filtering outgoing ethernet packets destined only for local devices on the same ethernet. The network interface reads outgoing packets received on a respective local ethernet segment, using the last byte of the MAC destination address of the packet header to index into a hash table of a linked list containing the first five bytes of respective stored MAC addresses of devices located on the subscriber ethernet segment. If the destination address exists in the linked list, the ethernet packet is dropped, since it belongs to the subscriber LAN segment and is not meant for further upstream transmission over the broadband access network. Since only the last byte of the destination address is used for hashing, a relatively small table of only two-hundred fifty-five entries can be used to index into the remaining five bytes of the respective stored MAC addresses, wherein the linked list keeps track of collisions on addresses linked to the same hash value.

Patent CA-2291034-A1 (CA)
Title: Detection of purine and pyrimidine nucleotides and underivatized nucleic acids by sinusoidal voltammetry
Inventor: KUHR WERNER G
IPC: G01N27/49
Filed: 1998-07-10
Abstract: Sinusoidal voltammetry was employed to detect both purine and pyrimidine-based nucleic acids. Adenine and cytosine, representing these two classes of nucleic acids, could be detected with nanomolar detection limits at a copper electrode under these conditions, where the sensitivity for adenine was much higher than that for cytosine. Detection limits for purine-containing nucleotides (e.g., adenosine 5'-monophosphate (AMP), adenosine 5'-diphosphate (ADP), and adenosine 5'-triphosphate (ATP)) were on the order of 70-200 nM using this method. These detection limits are achieved for native nucleotides and are over two orders of magnitude lower than those found with UV absorbance detection. Pyrimidine-based nucleotides could also be detected with high sensitivity due to the presence of a sugar backbone which is electroactive at the copper surface.

Title: Cement clinker and cement containing the cement clinker
Inventor: IKABATA TATSUO
IPC: C04B18/08
Filed: 1998-05-25
Abstract: An improvement is provided herein in cement for use in concrete of high strength and high flowability, mass concrete, shrinkage compensating concrete or concrete of high resistibility, which concretes are employed in the field of engineering and architecture or as building materials. The cement includes a cement clinker comprising A1 2O3 and Fe2O3, wherein the weight % ratio of A1 2O3 to Fe2O3 is 0.05 to 0.62, and a content of 3CaO-SiO2 is at least 35%. Thus, it has been found that, when the ratio of A1 2O3 to Fe2O3 is regulated to a value of 0.05 to 0.62, the strength of concrete of high strength and high flowability can further be improved, and the heat of hydration can be minimized, while the flowability of cement is improved and the long-term strength thereof can be maintained.

Title: Separation of minerals
Inventor: SENIOR GEOFFREY DAVID
IPC: B03B1/00
Filed: 2000-03-02
Abstract: A process for floating fine particles containing metal values of an iron-bearing sulphide mineral ore including the steps of conditioning the aqueous pulp of one at a pH of between about 7 and about 10 with a reducing agent which is preferably oxy-sulphur compound which dissociates to form oxy sulphur ions having the general formula:-S n O y z-where n is greater than 1; y is greater than 2; and z is the valance of the ion. A suitable collector is then added to the conditioned aqueous pulp to further condition the pulp and the pulp potential of the pulp raised to a sufficient level for the collector to adsorb onto the sulphide mineral ore. Gas is then bubbled through the aqueous pulp to subject the pulp to froth flotation. The froth from the flotation process is recovered to produce a concentrate of fine sulphide mineral and other metal values.    By conditioning the aqueous pulp at a pulp potential which dissolves the iron hydroxide film from the surface of the metal sulphide inclusions in the ore and subjecting the ore to froth flotation at a suitable pulp potential before the iron hydroxide can reform, the recovery of metal values in the fine ores can be greatly enhanced.
