Patent CA-2089315-C (CA)
Inventor: HALPERN B JAMES
IPC: H02J13/00
Filed: 1993-02-11
Granted: 2000-08-15
Abstract: A system for monitoring power usage of various devices at remote facilities is described. The system employs sensors at each facility to sense the on/off condition of the devices. A processor at each facility, under the control of a host computer at a central location, stores the output data of the sensors in stripped-down form. The host computer specifies to the processor at each facility the time and date at which it should begin polling the sensors, the interval between pollings of the outputs of the sensors, the time and date at which the processor should report to the host computer and transmit the stored data, and the address location to be used when the processor initiates polling of the data. A master clock/calendar at the central location is used to synchronize the clock/calendars at each facility. Thus, only stripped-down data and power outage information are required to be stored by the processor and transmitted to the host computer, without the need to store or transmit any other data such as sensor identification or time and date of polling with each sampling of data. This results in reduction of memory storage requirements and transmission time. Alternatively, rather than storing the on/off condition of the devices, sensors which generate analog currents of voltages representing the amount of power being consumed by the device can be used in conjunction with A to D converters to digitize the information for storage and transmission to the host computer.

Abstract: 1. A circuit analyzing system includes a current transformer for extracting current from a phase or neutral conductor of a three phase line, a filter connected to the output of the current transformer and functioning to substantially trap current at the fundamental frequency while substantially passing currents at various harmonic frequencies thereof, and signal processing circuitry connected to the output of the filter to perform various functions with the harmonic frequency current input thereto.

Other functions include a user or utility's connecting a demand circuit mechanism to the measured currents (preferably RMS/harmonic frequency currents), and/or using comparator circuitry to sense the measured harmonic frequency currents and, if they exceed a desired level set by the user or utility, to output a signal to a tripping device such as a power contactor or relay which will in turn institute load shedding.

Title: Method and system for designing a cutting tool
Inventor: WAYNE STEVEN F
IPC: G05B19/4097
Filed: 1992-06-12
Granted: 2001-12-11
Abstract: A method of designing a cutting tool uses finite element numerical models (14) to predict a response of the toot during a simulated cutting operation on a workpiece, and to simulate a chip-flow phenomenon occurring during the cutting operation. The chip-flow model (14) incorporates representations of a fracture mechanism describing a chip separation phenomenon, a heat-gen-erating mechanism describing a thermal coupling phenomenon, and a shear localization mechanism describing a shearing pheno-menon wherein these phenomena occur during the cutting operation. The predicted tool response and the chip-flow simulation are evaluated by an artificial intelligence system (18) to render rule-based judgments which are embodied in recommendations for continuously modifying the models (14) and input design variables until the simulation and response converge to an optimal re-sult.

Abstract: A process for the extraction of copper from a sulphide copper ore or concentrate comprises the steps of subjecting the ore or concentrate to agitation leaching at an elevated temperature and pressure to obtain a resulting acidic leach liquor containing dissolved copper and reducing the acidity of the resulting acidic leach liquor by effecting percolation leaching of a bed of low-grade copper ore or granular rock with the acidic leach liquor. In one embodiment, the agitation leaching is carried out in the presence of oxygen and water to obtain an acidic leach liquor containing sulphate and dissolved copper. In another embodiment, the agitation leaching comprises a first leaching step at an elevated temperature and pressure in the presence of oxygen and an acidic chloride solution as lixiviant and a second leaching step at atmospheric pressure with an acidic sulphate solution. In a preferred embodiment, the bed of low-grade copper ore or granular rock is in the form of a heap and the percolation leaching is a heap leaching process. Copper is extracted from the leach liquor by solvent extraction. Solvent extraction is effected either before or after the heap neutralization leach depending on the nature of the copper ore or concentrate being treated.
