摘要： A locomotive control system for performance assessment of a locomotive engine includes a controller and at least one sensor coupled to the controller. The at least one sensor is located proximal to the locomotive engine so as to gather actual performance data from the locomotive engine. The controller monitors locomotive current operating conditions and utilizes the current operating conditions to calculate predicted performance. The controller compares the predicted performance output based upon the current operating conditions with the actual performance data to monitor any substantial deviations therefrom.

摘要： A rotary machine has a stationary component with circumferential grooves and a rotatable component, as well as annular packing or sealing ring segments movable toward and away from the rotating component. To prevent circumferential displacement of the lower side packing ring segments by gravity forces and enable the lowermost segment in the lower housing to be moved radially inwardly, the side segments of the lower housing are supported adjacent the casing midline in a manner preventing downward movement and enabling horizontal movement. In an exemplary embodiment, the lower side packing ring segment is elongated so as to extend above the horizontal joint of the housing and a key bar extends from a key bar groove in the housing to engage a corresponding groove in the segment. The key bar may be disposed to define a seal key for the horizontal joint.

摘要： In a steam turbine, a combined brush and labyrinth seal is provided between a diaphragm web and a sealing surface on a rotatable component radially outwardly of the rotor surface. The contact between the brush seal and sealing surface lies along an axially upstream projecting flange of an annular platform such that heat generated by frictional contact between the bristles and the sealing surface has minimal effect on the rotor surface and hence rotor dynamics. A backup labyrinth seal is provided between the web and platform. Additionally, axially upstream projecting flanges are provided on the downstream buckets and which flanges are spaced radially outwardly of the rotor surface and lie in registration with the diaphragm web. Labyrinth teeth seal between the diaphragm web and the bucket flanges serving as a backup seal.

摘要： Apparatuses useable in an offshore drilling installation close to the seabed for controlling well influx within a wellbore are provided. An apparatus includes a centralizer and flow constrictor assembly, a sensor and a controller. The centralizer and flow constrictor assembly are configured to centralize a drill string within a drill riser and regulate a return mud flow. The sensor is located close to the centralizer and flow constrictor assembly and configured to acquire values of at least one parameter related to the return mud flow. The controller is coupled to the centralizer and flow constrictor assembly and the sensor. The controller is configured to control the centralizer and flow constrictor assembly to achieve a value of a control parameter close to a predetermined value, based on the values acquired by the sensor.
