Title: Control of lead nitrate addition in gold recovery
Inventor: FULTON MICHAEL
IPC: C22B11/08
Filed: 2001-03-13
Abstract: A method for controlling the extraction of gold from a gold ore by the cyanidation process in which a pre-leach including the addition of lead nitrate is used. In order to maintain stable conditions in the leaching process, and to use the leaching reagents efficiently, a potassium permanganate titration step is used to monitor the apparent concentration of thiocyanate in the cyanidation step. This value has been found to be directly related to the rate of addition of lead nitrate in the pre-leach step. Further, the rate of addition of lead nitrate is also directly related to both the time required for, and the efficiency of, the cyanidation step. By establishing a target value, and a preferred range for the apparent thiocyanate concentration based on the properties of the ore being processed, optimal extraction conditions can be established and maintained by monitoring the apparent thiocyanate concentration.

Title: Sorting and acquiring image data for documents
Inventor: DEWITT ROBERT R
IPC: G06K9/00
Filed: 1999-09-24
Abstract: An apparatus (10) is provided for sorting a group of documents contained with an envelope into selected batches of documents. An envelope feeder (15) feeds a group of envelopes containing documents onto a document transport (75). A document extractor (50) extracts the documents from the envelopes. A system controller (95) identifies the documents extracted from each envelope along with the envelope as a single transaction along the path of movement. An orientation detector (135, 140) determines the orientation of selected documents. A document orientor (150, 170) changes the orientation of documents into a desired orientation. An image acquisition device (230) acquires an image of the envelopes and selected documents conveyed to enable the system controller to assign documents and the envelope from which it was extracted into selected transactions and batches. A non-volatile image storage medium stores the acquired images of the envelopes. A document sorter sorts the documents and envelopes of respective batches into selected output areas.

Title: Quality priority image storage and communication
Inventor: GOERTZEN KENBE D
IPC: H04N7/26
Filed: 2000-02-04
Abstract: An image processing scheme that minimizes (175) the amount of data required to process an input image signal (120) but which maintains a guaranteed desired  image quality level is disclosed. Transformation (185) and quantification (190) removes redundant data from the input image signal and provides a symb ol set that is represented by a determined total data content. A peak data rate  is determined from the total data content and any encoding overhead. The quality of image processing is determined based upon the transformation and quantification settings. Quality priority processing ensures that the available data rate is at least equal to the peak data rate. Transformation and quantification can be adjusted where a determination is made that the pe ak data rate exceeds the available data processing rate, or where the determine d quality level does not exceed the selected quality level.

Title: Methods and apparatus for selecting multicast ip data transmitted in broadcast streams
Inventor: COURTNEY JONATHAN D
IPC: H04N5/44
Filed: 2000-07-13
Abstract: Through the association of an unique IP address with each data stream, a single system may be used by a network card or a tuner to select multicast IP  data. More particularly, a locator adapted for identifying a data stream is obtained. The locator is then mapped to an IP address. Through the use of this mapping, a digital television receiver may obtain the appropriate locator to read the associated data stream. It is then determined whether the IP address corresponds to a data stream locator associated with a data stream. If this is the case, a tuner is instructed to read the data stream associated with the data stream locator. However, if the IP address does not correspond to a data stream locator, a network card identified by the IP address is instructed to read data from the associated network. Since each data stream may be associated with a plurality of multicast IP addresses, a multicast group address is specified to identify the appropriate multicast IP data transmitted in the data stream. Packets addressed to the multicast group address may then be received by either a tuner or a network interface card.

Title: Differential dense wavelength division multiplexing (ddwdm) in optical systems
Inventor: SARRAF MOHSEN
IPC: H04J14/02
Filed: 2002-04-04
Abstract: An apparatus provides an optical wavelength division multiplexed signal having 2M optical channels such that each of M information-bearing signals are differently encoded onto 2 of the 2M optical channels. In particular, the apparatus comprises M inverters, 2M electrical-to-optical converters and a multiplexer. Each electrical-to-optical converter provides an optical signal at a different one of 2M wavelenghts. The apparatus receives the M information-bearing signals and (a) creates M optical signals, each at a different wavelength, by converting each of the M information bearing signals onto the optical domain via M of the 2M electrical-to-optical converters, and (b) creates M inverted optical signals, each at a different wavelength, by first inverting each of the M information bearing signals (via the M inverters) before conversion into the optical domain via the remaining M electrical-to-optical converters. The M optical signals along with the M inverted optical signals are then applied to the multiplexer, which provides an optical wavelength division multiplexed (WDM) signal having 2M channels.
