Patent CA-2359593-C (CA)
Inventor: KIM JINMAN
IPC: H04L12/28
Filed: 2001-10-23
Granted: 2007-03-27
Abstract: To provide suitable QoS in a WLAN distributing voice, data and multimedia broadband in any end-to-end context, RF link errors are monitored in real time and applied as input to recovery and corrective procedures. The performance measures considered in normally evaluating a link QoS include throughput (bandwidth), delay, jitter and bit error rate (BER) but these alone. do not properly evaluate a QoS for real-time services. In the exemplary embodiment, the frame error rate (FER) is compared with a threshold to define quality. If the error threshold is exceeded recovery procedures are instituted to restore the desired signal quality. The exemplary WLAN system has a capacity for providing isochronous services, such as broadband multimedia (including high speed video) and real-time toll quality voice service, and includes real time error detection and recovery procedures to maintain a desired individualized Quality of Service (QoS) appropriate for individual services.

Title: Control of lead nitrate addition in gold recovery
Inventor: DESCHENES GUY
IPC: G01N31/16
Filed: 2002-01-16
Granted: 2009-05-26
Abstract: A method for controlling the extraction of gold from a gold ore by the cyanidation process in which a leaching step including the addition of a lead compound, which is typically lead nitrate or other lead salt, is used. In order to maintain stable conditions in the leaching process, and to use the leaching reagents efficiently, an analysis step is used to monitor the concentration of thiocyanate in the cyanidation step. This value has been found to be directly related to the rate of addition of the lead compound in the pre-leaching or leaching step. Further, the rate of addition of lead compound 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 thiocyanate concentration based on the properties of the ore being processed, optimal extraction conditions can be established in the leaching process and maintained by monitoring the thiocyanate concentration. By the use of an automated potassium permanganate titration procedure as the analysis step, the thiocyanate concentration can be measured on line with only a short delay.

Abstract: In a wireless system comprising a plurality of radio base station, each base station services a portion of the system. A cache is associated with each base station. The cache stores files regularly requested by the remote unit within the coverage area of the corresponding base station. When a base station receives a message from a remote unit, it parses the message to determine if the message comprises a file request. If so, the base station determines whether the file is available from the cache. If available, the base station responds to the request by forwarding the requested file from the cache. If the file is not available, the base station forwards the message to a central controller, which retrieves the file via the Internet from the appropriate content server and provides it to the base station.

A device for resonant excitation of liquid comprises a rotor with the working wheel, made as a disc and an annular wall with a series of outlet openings, and a stator with the intake opening, communicating with the cavity of the working wheel and a coaxial wall forming with the working wheel an annular chamber, communicating with the discharge opening.  At that R = 2.8477729 n-2/3.cndot.10 4 [mm], while the value of the internal radius of the coaxial wall constitutes R1 = R + B S (2 .pi.)-1 [mm], where B >=1 - the selected integer, S = 7.2973531 [mm] - the pitch of outlet openings of the working wheel.     A method of fractionation of liquid includes preliminary treatment thereof with the help of the above-described pre-installed device for resonant excitation, the supply of the preliminarily treated liquid into a fractionating tower and the discharge of distilled fractions and residual fraction. The preliminary treatment is applied preferably to a partial flow of liquid diverted from the main flow.   A plant for fractionation of liquid comprises a feeding pump, at least one fractionating tower and the above-described pre-installed device for resonant excitation, sequentially installed between the feeding pump outlet and the fractionating pump inlet.  Shut-off-control elements are provided for diverting of the partial flow of liquid and combining thereof with the general flow following the preliminary treatment.
