Abstract: Prioritization logic determines the final commmand applied to a process control component (3) from a plurality of commands generated by diverse independent control subsystems (5A, 5B, 5N), each utilizing different hardware and software to implement a common algorithm to preclude common mode failures. In one embodiment, priority is given to commands generated by one control subsystem, such as a safety grade subsystem, over commands provided by a second, non-safety grade control subsystem. In another embodiment, equal priority is given to commands from two control subsystems. In this case, ambiguous commands from either or both subsystems are ignored, but conflicting commands produce a final command which provides a safe state.

Abstract translation: 优先级逻辑确定从多个独立的控制子系统（5A，5B，5N）生成的多个命令中应用于过程控制组件（3）的最终的标记，每个命令都使用不同的硬件和软件来实现一种通用算法来排除共模故障 。 在一个实施例中，优先考虑由一个控制子系统（例如安全等级子系统）通过由第二非安全等级控制子系统提供的命令产生的命令。 在另一个实施例中，给予来自两个控制子系统的命令相同的优先级。 在这种情况下，来自任一个或两个子系统的不明确的命令将被忽略，但冲突的命令会产生一个提供安全状态的最终命令。

Abstract: A variable area restrictor is disclosed that is preferably used in a turbine engine to provide improved matching between the pressure required for aerofoil cooling and the somewhat lower pressure requirement for supplying air to the interstage seals and disc cavities. In a preferred embodiment, the valve of the present invention comprises a spring loaded valve assembly with a fixed minimum flow area controlled by pre-setting a minimum dimension for the opening between an inlet and the housing or body of the valve. A pre-loaded spring maintains the lift at this minimum dimension until the pressure drop across the flow area exceeds a certain value. Above this critical pressure drop, the valve lifts, causing the flow area to increase, and thereby reducing the supply pressure that would be otherwise necessary to achieve a disc cavity flow adequate to maintain the temperatures within specifications.

Abstract: A nuclear reactor plant has a nuclear reactor vessel in a containment vessel. Air ducts, sump discharge lines, service water lines and other non-process non-critical lines extending through the wall of the containment vessel can be isolated passively (i.e., without instrumentation and control systems or power) should a postulated event which raises the atmospheric temperature within the containment vessel occur. The passive containment isolation system includes an isolation valve disposed in the non-process line and an actuator responsive to the atmospheric temperature within the containment vessel. The actuator is operatively connected with the isolation valve for closing the non-process line in response to the atmospheric temperature. The actuator is preferably disposed in or adjacent a containment sump at the bottom of the reactor vessel or adjacent the reactor vessel cavity where the temperature of the local atmosphere will most rapidly rise.

Abstract: A method for removing scale, sludge, corrosion and other debris and deposits from the interior of a heat exchanger vessel such as a nuclear steam generator, includes generating pressure pulses in a non-corrosive, strongly basic, amine-containing chemical cleaning agent in aqueous solution after the agent has been introduced into the interior of the vessel. The chemical cleaning agent is an aqueous solution containing at least one of the group of lower alkyl amines and cyclic diimines or combinations thereof. The method further includes simultaneously recirculating the chemical cleaning agent through a filter assembly during the pressure pulsing operation in order to remove fluidized sludge and corrosion products dislodged by the pressure pulsing and chemical action. The method reduces the time required for a particular chemical cleaning agent to effectively clean the vessel and the number of times such chemicals need to be introduced into the vessel, which in turn results in the production of less radioactive liquid waste, and minimizes new corrosion through use of relatively non-corrosive cleaning agents.

Abstract: A process for recovering iron from an iron oxide bearing mass. The process includes forming a bed (27) of lump coke (28) in a vertical shaft furnace (11), feeding the iron oxide bearing mass and scrap metal onto the bed (27) of lump coke (28) and combusting the coke (28) in the coke bed (27) while injecting a plasma gas having a temperature greater than about 5,000 DEG F into the coke bed to form a reaction zone (33) within the coke bed (27) having a temperature in excess of 4,000 DEG F. The iron oxide bearing mass and scrap metal fed onto the bed (27) of lump coke (28) is molten to form a molten phase containing molten iron oxide and molten scrap metal. The molten phase flows into the reaction zone and a film is formed on the lump coke within the reaction zone, the iron oxide in the film being reduced by carbon from the coke to form molten iron (22) in a solid/liquid reduction. The molten iron (22) is discharged from the furnace (11).
