The Canola Council of Canada is calling on the federal government to “consider all available options” amid a trade dispute with China that has resulted in suspended seed shipments from two exporters.China suspended the licenses of Richardson International Ltd. and Viterra Inc., citing concerns about pests, and Chinese companies stopped buying seed from Canadian producers in recent months.The council’s president Jim Everson says in a statement that the group has seen little sign that China wants to engage in a science-based discussion and it needs Ottawa to consider all available options.It recommends Canada appoint an ambassador to China as soon as possible, and review diplomatic, technical and legal tools to engage Chinese officials in resuming trade, among other things.The seed dispute comes after Canadian authorities arrested Chinese tech executive, Meng Wanzhou, in Vancouver in December at the behest of the U.S.The council says China’s been a major market for Canadian canola and accounts for about 40 per cent of all seed, oil and meal exports.The Canadian Press
Chad has become the 100th nation to agree to give the United Nations International Atomic Energy Agency (IAEA) more information about its nuclear activities, which the agency hailed as a milestone in efforts to bolster global nuclear verification efforts.The so-called Additional Protocol furnishes IAEA inspectors with enhanced access to information and locations of nuclear activity.“I welcome this latest entry into force and call on all States that have not yet done so to bring into force Additional Protocols without delay,” IAEA Director General Yukiya Amano said in a press release issued in Vienna.The Protocol, he stressed, is of “vital importance,” since it allows the IAEA to determine both whether declared nuclear material is being diverted from peaceful uses and whether countries are in possession of undeclared nuclear material.More than four decades ago, the Nuclear Non-Proliferation Treaty (NPT) tasked the IAEA with verifying that nuclear material and activities in non-nuclear-weapons States are not used for military purposes.In 1997, the agency’s Board of Governors adopted additional measures to boost the effectiveness and efficiency of the safeguards system.Chad’s notification yesterday comes as more than 100 nations are taking part in the five-yearly review conference of the NPT, the cornerstone of the world’s nuclear non-proliferation regime, to discuss how to further full implementation and enhance the universality of the pact.At the start of the nearly month-long gathering last week, Secretary-General Ban Ki-moon exhorted countries to take decisive action to build a safer world.“We have a choice: to leave a legacy of fear and inaction… or to act with vision, courage and leadership,” he told the conference.“We all know it is possible,” the Secretary-General said of disarmament and non-proliferation, which have been among his top priorities since taking office in 2007.He characterized the NPT as one of the most important global treaties ever reached. With the nuclear threat still real, “we need this regime as much as ever,” Mr. Ban underscored.The last NPT review conference in 2005 was a failure, he said, having wrapped up without any substantive agreement having been reached. “This time, we can – and must – do better.” 14 May 2010Chad has become the 100th nation to agree to give the United Nations International Atomic Energy Agency (IAEA) more information about its nuclear activities, which the agency hailed as a milestone in efforts to bolster global nuclear verification efforts.
Chinese coal mining group Xishan Jinxing Energy is using three Voith fill-controlled 866 TPKL fluid couplings underground in the powerful 4.8 MW drive of the main belt conveyor in the Xiegou No 12 coal mine in Shanxi Province. The three 1,600 kW drives power the 1,900 m long main inclined belt conveyor. This conveyor transports 3,800 t/h of coal so powerful and reliable couplings are required and the company opted for the 866 TPKL Voith fluid coupling. Voith states: “Through controlled application of torque, the fluid coupling pretensions the belt slowly and permits smooth conveyor start-up. This controlled soft start protects the belt and driveline components and extends their lifetime. As a result, the Voith fluid coupling reduces unplanned downtime – the operator benefits from lower maintenance costs and continuous production. Regardless of the load state of the belt, start-up times of up to three minutes are possible. Thanks to stand by cooling of the operating oil, the 866 TPKL fluid coupling also permits multiple conveyor start-ups in succession, even when the belt is loaded.”The mine operator is described as being very satisfied with the performance of the 866 TPKL. In contrast to other solutions, the compact fluid coupling is also very capable of withstanding extreme environmental conditions such as dust, dirt, moisture, heat or cold. As in every hydrodynamic coupling, power transmission in the 866 TPKL is virtually wear-free. For the operator, this translates into lower maintenance and repair costs for the coupling. In addition, motors start up independent of the machine load, and through sequenced starting of the motors, the fluid coupling reduces the load on the power supply circuit.An additional benefit of the 866 TPKL is its ability to operate with reduced filling to drive an empty conveyor at a reduced speed. During the creep speed operation, less power is transmitted and the belt runs more slowly. This function is useful for the visual inspection of the belt and splices. In the Xiegou No 12 coal mine, the fluid couplings were operated in the partially filled mode during commissioning to be sure that the belt was tracking properly. With the fluid couplings operating in the partially filled mode, the belt speed could be reduced to 1.2-1.7 m/sec instead of operating at the rated speed of 4.5 m/sec. Until now, the coal mine has been operating at the initially planned production capacity of 15 Mt/y but the operator plans to increase production capacity in the next one to two years. This will require the main belt conveyor to be upgraded with a fourth drive. For this, the operator plans on installing an additional 866 TPKL fluid coupling from Voith.
