IPC: H01F27/245
Filed: 2000-03-28
Abstract: In a method of making a pencil core having a plurality of substantially flat laminations wherein at least one lamination at the center of the core is wider than the other laminations, a flat strip of core steel is fed into a progressive die, and a plurality of scrap region blanking stations is provided each of which blank out two spaced parallel regions from the strip, but with each of the scrap region blanking stations blanking out the regions at a different spacing. At an embossing station, at least one embossment is provided in at least each of the laminations preceding the last lamination.  After all of the scrap region blanking stations, a blanking and stacking station first blanks laminations free from the strip at and corresponding to the parallel scrap regions of different spacing, and as each lamination is blanked free from the strip, that lamination is stacked onto the previously blanked laminations to form completed cores, the completed cores being held in a choking section of the blanking and stacking station. This die can also have multiple rows.

Title: Distributed computer database system and method for performing object search
Inventor: BACLAWSKI KENNETH P
IPC: G06F17/30
Filed: 1999-07-23
Abstract: A distributed computer database system including one or more front end computers and one or more computer nodes interconnected by a network into a search engine for retrieval of objects including images, sound and video streams, as well as plain and structured text. A query is an object in the same format as the objects to be retrieved. A query from a user is transmitted to one of the front end computers which forwards the query to one of the computer nodes, termed the home node, of the search engine. The home node extracts features from the query and hashes these features. Each hashed feature is transmitted to one node on the network. Each node on the network which receives a hashed feature uses the hashed feature of the query to perform a search on its respective partition of the database. The results of the searches of the local databases are gathered by the home node.

Title: Calibration of subscriber terminal for wireless telecommunications system
Inventor: LYSEJKO MARTIN
IPC: H04B1/38
Filed: 1998-11-13
Abstract: The present invention provides a subscriber terminal for communicating over a wireless link with a central terminal of a wireless telecommunications system, the subscriber terminal comprising a first signal processing unit (110) associated with an antenna (100) to transmit and receive signals over the wireless link, a second signal processing unit (130) remote from the first signal processing unit (110) and associated with an item of telecommunications equipment (150) to pass signals between said item of telecommunications equipment and the first signal processing unit (110), and a connection medium (120) connecting said first and second signal processing units. In accordance with the present invention, calibration logic within said second signal processing unit (130) is arranged to provide on the connection medium (120) control signals used to control circuitry in the first signal processing unit (110) to cause signals to be passed on the connection medium from the first signal processing unit to the second signal processing unit to enable the calibration logic to determine a signal loss introduced by the connection medium (120). Compensation circuitry is then driven by the calibration logic to compensate for the signal loss determined by the calibration logic. By this approach, the amount of circuitry required within the first signal processing unit associated with the antenna can be reduced, thereby reducing the complexity of the first signal processing unit, whilst still allowing for determination of the compensation required to compensate for losses to received and transmitted signals resulting from the passing of those signals over the connection medium.
Patent CA-2313135-A1 (CA)
Inventor: HILDEBRAND MARTIN
IPC: B01F13/00
Filed: 2000-06-29
Abstract: A header for use in transmitting gases or fluids beneath the surface of a body of water is herein described. The header comprises a first pipe arranged for transmitting the gas or fluid, a second pipe arranged to hold either water or air and ballast means for adding weight to the header. Specifically, the ballast means is arranged such that the header floats on the surface of the body of water when the second pipe is filled with air. In use, the header is laid out across the surface of a body of water and the first pipe is connected to a source of the fluid to be transmitted, for example, air, oil, natural gas, or liquid hydrocarbons. Water is then pumped into the second pipe, which displaces the air in the second pipe and increases the specific weight of the header, thereby causing the header to sink below the surface of the body of water. As the header is below the surface, water traffic is not restricted by the transfer of fluid across the body of water. For maintenance, compressed air is pumped into the second pipe, replacing the water in the second pipe and causing the header to float to the surface of the body of water. This arrangement may also be used for aerating or de-icing bodies of water, such as, for example, lakes, channels and lagoons.

Title: An optimization tool for robot placement
Inventor: BARRAL DAVID
IPC: B25J13/00
Filed: 2000-10-03
Abstract: A method and system for optimizing the placement of a robot in a workplace so as to minimize cycle time is defined. A modified simulated annealing method (SA) is applied to the problem of robot placement in CAD systems, in the context of welding tasks. The objective function for optimization is cycle time, which can be obtained from available robotic CAD software. The research domains are simplified, and the SA method is applied to yield an optimal or near-optimal solution to each problem. To obtain the optimal placement of the robot, the research domain is first simplified by determining an acceptable base location domain, then obstacle shadows, which are subtracted from the previous domain to give the free acceptable base location domain. A modified SA method is applied to this domain, using task feasibility tests before simulating the cycle time, in order to save CPU time. The modified SA algorithm gives the global optimal placement, together with other local minima and an estimate of an efficient region where the robot may be positioned.
