Abstract: A process for selectively reducing calcine from a copper/nickel containing sulfidic material includes subjecting the calcine to a mildly reducing atmosphere at relative high temperatures. CuO is selectively converted to Cu2O which can easily be separated by leaching from other metals which may be present in the material.

Abstract: A one-piece grommet able to receive auxiliary wires without a sacrifice in sound-dampening properties contains: a main body having a primary passageway for receiving a wire harness; an annular body having an acoustic chamber formed in a front flange portion thereof and an annular panel-fitting groove formed between intermediate and back flange portions thereof; a secondary passageway formed between the annular and main bodies and disposed for receipt of an auxiliary wire; and a back annular rim section defined between the main and annular bodies and having one or more through-holes and one or more hollow protruding members having removable ends and covering the through-hole(s), the through-holes and protruding members being disposed in communication with the secondary passageway. The secondary passageway does not pass through the acoustic chamber, the annular panel-fitting groove or the primary passageway.

Abstract: An automatic utility meter is provided for collecting, calculating, storing and displaying data correlative of consumption of utility commodities such as electric power, gas, water and the like. In addition, the automatic utility meter includes communication means which allows bi-directional communication of data to and from a remote computer. The automatic utility meter is a direct replacement for existing electric utility meters and uses direct read circuitry to sample and calculate power directly from the input voltage and current waveforms received from an electric utility company.

Abstract: An information display system uses data comprising graphical images of pages of a publication and text data. The images comprise images of both text and non-text matter, where the text matter includes a plurality of predefined passages of text, and the text data comprises the plurality of predefined passages of text. A display is provided to simultaneously display at least a part of a page of the image and a selected predefined passage of text. A user operable selector is provided to enable a user to select a portion of the page of the image displayed by the display whereby the display simultaneously displays the selected predefined passage of text as well as the page of the image.
