Abstract: The purpose of the present invention is to provide a method for producing a high-purity nickel sulfate with less impurities, especially with less magnesium or less chlorides by regulating the concentration of the extractant and the pH concentration during the processing in a step for obtaining a nickel sulfate solution with high nickel concentration by means of solvent extraction using an acidic organic extractant. A method for producing a high-purity nickel sulfate, which is characterized by processing an acidic solution containing nickel through at least the following steps: a sulfurization step wherein a sulfurizing agent is added into the acidic solution containing nickel, thereby obtaining a sediment of a nickel sulfide and a liquid after sulfurization; a redissolving step wherein a slurry of the nickel sulfide obtained in the sulfurization step is prepared and an oxidant is added into the slurry, thereby obtaining a concentrated solution of nickel; a liquid cleaning step wherein the concentrated solution of nickel obtained in the redissolving step is neutralized by adding a neutralizing agent thereto, thereby obtaining a neutralization sediment and a concentrated solution of nickel after deironization; and a solvent extraction step wherein the concentrated solution of nickel after deironization obtained in the liquid cleaning step is subjected to solvent extraction, thereby obtaining a back extraction liquid and a nickel sulfate solution.

Title: Location and monitoring of undersea cables
Inventor: MCEWEN-KING MAGNUS
IPC: H02G1/10
Filed: 2012-12-20
Abstract: The present application described methods an apparatus for locating and/or monitoring subsea cables (101) having an optical fibre (105) deployed along its length. The optical fibre (105) is connected to a distributed acoustic sensing (DAS) interrogator unit to interrogate the optical fibre to provide a fibre optic DAS sensor. To locate the cable an acoustic stimulus is transmitted into the water from one or more known locations. The time of arrival of an acoustic signal matching the stimulus at the sensing portions of the DAS fibre can be detected and used to determine information about the location of those sensing portions to the known location. The DAS signals returns can also be monitored under ambient conditions to detect any signals indicative of likely damage to the cable.

Abstract: A system and process for removing divalent cations from a rich MEG feed stream (15, 85) is presented. An ion exchange bed (20) containing a cation exchange resin adsorbs the divalent cations in the rich MEG feed stream (15, 85) as it flows through the ion exchange bed (20). After the divalent ions have been removed, the feed stream flows through a flash separator (30) and a distillation column (45) to reclaim MEG. Alternatively, the feed stream flows through a distillation column (45) to regenerate MEG. The spent cation exchange resin may be regenerated in place using a regeneration brine (65) comprised of sodium chloride (80) and water. After use, the regeneration brine (65) may be disposed as waste or recycled to the brine storage tank (60) and re-used to regenerate the cation exchange resin.

Abstract: An expandable threaded connection between segments of expandable tubulars that provides a high bearing pressure seal at a specific area along the pin and box members is disclosed. The invention utilizes a "groove" in a surface of the box member and a corresponding "rib" on the pin nose. The radial expansion of the tubulars causes the pin to become shorter in length, thereby causing the pin nose to retract from the back of the box member. As the pin nose retracts, an axial gap is formed between the pin elements of the mating tubulars.

Abstract: A low-power wireless communication device is in a sleep or standby mode of operation for extended periods of time, periodically becoming fully operational and issuing a "check in"  message to a base station, thereby inhibiting the ability of the base station to assist in the locating of device, and remotely updating the settings or operational programming of the device much of the time. Upon receipt of a command to locate a misplaced low-power wireless device or to update the device, a base station queues an associated command in a task queue. Upon receipt of a check-in message from an associated low-power wireless device, indicating it is in a fully powered and communicative state of operation, the base station searches its task queue for applicable commands relative to the specific wireless device and executes them via communication with the now fully-operational wireless device.
