Title: Method and apparatus for performing the register functions for a plurality of metering devices at a common node
Inventor: OUELLETTE MAURICE JOSEPH
IPC: H02J13/00
Filed: 1997-04-14
Abstract: A method and apparatus of the present invention includes a common node of a power line communications system for individually performing the register functions for a plurality of electrical metering devices operably connected to the node. The power line communications system includes at least one node having a plurality of registers, a respective one of which is associated with a respective electrical metering device. The electrical metering devices connected via the power lines to the node measure the power consumption of the electrical load associated therewith and transmit a signal indicative of the measured power consumption to the node and, in particular, to the respective register of the node associated with the electrical metering device. The node individually determines the power consumed by each electrical load operably connected to the node based upon the received signals. The results of such calculations are stored in the register associated with each respective electrical metering device. The stored results are also periodically transmitted to the system control center of the power line communications system. Thus, the register functions for a plurality of relatively simple electrical metering devices may be centralized at a common node.

Title: Process for the fluid catalytic cracking of heavy feedstocks
Inventor: MEDEIROS JORIVALDO
IPC: C10G11/16
Filed: 1997-09-16
Abstract: A process for the fluid catalytic cracking of heavy feeds under a heat balance regime is described, where one or more catalyst coolers external to the regenerator cool a stream of regenerated catalyst. A portion of said stream returns to the regenerator and a portion of the cooled regenerated catalyst is admixed to the non-cooled regenerated catalyst at a temperature substantially lower than the regenerator temperature, said admixture being brought into contact with the hydrocarbon feed to be cracked. As a result, the control of the catalyst circulation is rendered independent from the heat balance of the unit, with minimization of the thermal cracking, and therefore lower coke and fuel gas products.

Title: Intelligent control of aluminium reduction cells using predictive and pattern recognition techniques
Inventor: MEGHLAOUI ABDELHAMID
IPC: G05B13/02
Filed: 1998-03-02
Abstract: A neural control logic scheme based on prediction and pattern recognition techniques is used to control electrochemical processes such as aluminum electrolytic cells.  The predictive capacity of feedforward neural networks is used to predict the future values of decision variables to be used by the cell's control logic, enabling the control logic to apply anticipated actions to cells at different states, thus avoiding anode effects and improving cell stability. The pattern-recognition capacity of LVQ-type neural networks is used to provide a closed-loop control structure to the feeding of the cell as a function of cell resistance, alumina concentration and cell state. The closed-loop control structure enables the cell to operate at a near-optimal regime regardless of cell state.
