摘要： A pneumatic system installed on a vehicle and method of using the system to preheat compressor oil and/or components of the system to promote operation in cold weather conditions. The pneumatic system includes a compressor that generates compressed air in which oil is entrained, a separation tank that separates the oil from the air prior to the oil being returned to the compressor, and a heating element located within the separation tank and contacting the oil within the separation tank. Engine coolant of an engine cooling system of the vehicle flows through the heating element and the heating element transferring heat from the engine coolant to the oil within the separation tank to increase the temperature of the oil.

摘要： A motor-driven centrifugal pump for circulating a coolant in a primary circuit of a nuclear reactor comprises a sealed motor unit, a hydraulic part and a shaft which is immersed in the coolant, turned by the sealed motor unit and pumping the coolant by an impeller of the hydraulic part secured to the shaft. The motor unit comprises a dry stator and an immersed rotor, mounted securely on the shaft. The motor-driven pump also comprises an immersed flywheel mounted securely on the shaft between the rotor of the motor unit and the impeller of the hydraulic part, allowing a minimum slowing-down time after the electrical power supply is cut; and an immersed anti-backspin device, configured to mechanically block the rotation of the shaft in a predetermined direction.

摘要： A system, apparatus, and method for transferring chemical solutions and synthesizing a tracer. For transferring chemical solutions, the system comprises a primary container; a secondary container; a first line in communication with the primary container and the secondary container. The first line facilitates the flow of gas and/or liquid between the primary container and the secondary container. A valve located upstream of the secondary container and downstream of the primary container regulates flow within the first line; a second line in communication with the secondary container. For synthesizing a tracer, the system includes a source of a solution having a radionuclide. A first container has a tracer precursor and is in communication with the source of solution.
