Title: Procedure to leach copper concentrates, under pressure and at ambient temperature, by forming a colloidal mass in a sulfate - chloride medium
Inventor: FAINE JAIME RAULD
IPC: C22B15/14
Filed: 2004-07-28
Granted: 2011-02-01
Abstract: A chemical process to leach copper concentrates in the presence of a concentrated solution of sulfates and chlorides. The process includes forming a high reactivity chemical colloidal mass containing a high concentration of ions in the liquid phase of the colloidal mass which react with copper ores and forms a series of soluble salts. The salts are extracted by a simple wash. Mixing equipment for handling high viscosity liquids is used. The total mixing time is about 5 minutes, after which the colloidal mass is poured into a rectangular mold, of several hundred meters per side, and is left to settle and breathe. During settling, water and sulfuric acid are added at intervals to replace that consumed by the reactions taking place during the aeration, until the reactions have virtually end. This treatment results in a dry, very resistant mass, containing the copper extracted in form of chlorine salts, and sulfate.

Title: System and method for treating drilling mud in oil and gas well drilling applications
Inventor: DE BOER LUC
IPC: E21B21/00
Filed: 2004-03-16
Granted: 2011-08-23
Abstract: A system and method for controlling drilling mud density at a location either at the seabed (or just above the seabed) or alternatively below the seabed of wells in deep water and ultra deep water applications are disclosed. The present invention combines a base fluid of lesser density than the mud required at the wellhead to produce a diluted mud in the riser. By combining the appropriate quantities of drilling mud with base fluid, a riser mud density at or near the density of seawater may be achieved. The present invention also includes a wellhead injection device for injecting the base fluid into the rising drilling mud. The riser charging lines are used to carry the low density base fluid to the injection device for injection into the return mud. At the surface, the diluted return mud is passed through a treatment system to cleanse the mud of drill cuttings and to separate the heavier drilling mud from the lighter base fluid. The present invention further includes a control unit for manipulating drilling fluid systems and displaying drilling and drilling fluid data.

Title: Method and apparatus for scalable virtual private network multicasting
Inventor: NAPIERALA MARIA H
IPC: H04H20/00
Filed: 2005-12-21
Granted: 2012-03-20
Abstract: In one embodiment, the present invention is a method and apparatus for scalable virtual private network multicasting. In one embodiment a service network builds a new data multicast distribution tree for each high-bandwidth multicast data flow (e.g., multicast data flows that require an amount bandwidth meeting or exceeding a predefined threshold). However, if the multicast data flow is a low-bandwidth flow (e.g., if the required amount of bandwidth falls below the predefined threshold), the multicast data flow is routed over an existing multicast distribution tree in order to minimize an amount of state information that must be maintained by service provider core routers in the backbone network.

Abstract: A Virtual Access Core (VAC) manages and controls access to virtual machines. A Virtual Instruction Routine (VIR) protocol is used by all components of the system to pass instructions and information about a Virtual Session. The VAC issues commands in the VIR protocol language causing virtual machines to start and stop. A VIR host that hosts virtual machines responds to VAC commands. Web clients access the system via links, which a web server uses to send access requests to the VAC. The VAC responds by searching through process memory and database tables for information about free slots on a plurality of VIR hosts grouped into a Host Array. When one or more free slots have been identified, the VAC issues VIR Protocol commands instruction one or more VIR Hosts to load and start specific virtual machines in Specific Slots.

Granted: 2011-11-22
Abstract: In a mobile communication device, a scanning operation is performed with use of a wireless transceiver to identify one or more available wireless communication networks in a given coverage area. Each time the scanning operation fails to result in any connection between the mobile device and a wireless network, the scanning operation is repeated after delaying for a next delay period of a plurality of scanning delay periods n = [n1, n2, ..., upper limit]. Initially, an upper limit of the plurality of scanning delay periods n = [n1, n2, ..., upper limit] is established at a value of M. During operation, the mobile device monitors to identify whether a predetermined battery condition, such as a low battery capacity or high battery discharge rate, exists. If the predetermined battery condition exists, the upper limit of the plurality of scanning delay periods n = [n1, n2, ..., upper limit] is reestablished at a value of N > M. If a more severe battery condition exists, the upper limit of the plurality of scanning delay periods n = [n1, n2, ..., upper limit] is reestablished at a value of P > N > M. Advantageously, power consumption is reduced during adverse battery conditions of the mobile device.

Title: Method and device for decoupling and/or desynchronizing neural brain activity
Inventor: TASS PETER
IPC: A61B5/374
Filed: 2005-04-28
Granted: 2012-10-02
Abstract: The invention relates to a device for decoupling and/or desynchronizing neural, pathologically synchronous bra n activity, in which, according to the invention, the activities in a partial region of a brain area or a functionally associated brain area are stimulated by means of an electrode, surprisingly resulting in decoupling and desynchronizing the affected neuron population from the pathological area and suppression of the symptoms in a patient. In an alternative embodiment of the device, the pathologically synchronous brain activity due to the disease is desynchronized which also leads to the symptoms being suppressed. As a stimulus, the feedback stimulation signal, that is to say the measured, time delayed and processed neural activity is used, whereby the stimulation signal is controlled on demand in a self-regulating manner according to the invention as a result of which the intensity of the resultant stimulation influence on the neuron population to be decoupled or on the neuron population to be desynchronized is automatically minimized after successful decoupling and/or desynchronization. To operate successfully, the device needs neither elaborate calibration nor control of the stimulation parameters but these can be adapted and optimized preferably by the additional control system. The device comprises a stimulation electrode (2) and at least one sensor (3) which are driven by a control system in such manner that they produce decoupling and/or desynchronization i n their local environment.
