Abstract: A surface plasma actuator includes a conducting wire attached to a surface of a target object and electrically insulated from the target object. Surface plasma is generated along a neighborhood of the conducting wire by applying a pulse voltage between the conducting wire and a conductive portion on a side of the target object. An induced gas flow is generated by the surface plasma.

Abstract: A bottom discharge open topped hopper car has a center sill with a bottom flange having laterally protruding edges. A shed plate assembly is provided to discourage accumulation of product on the exposed upwardly facing shelf otherwise presented by the bottom flange protrusions. The shed plate assembly may be mounted to the center sill in a manner that avoids impairment of the stress performance of the flanges of the center sill, whether by mechanical fastenings to other objects, or welding to objects that are not the center sill. The shed plate assembly may have walls having upper margins that are higher than the upper extremity of the hopper discharge opening such that the shelf of the center sill bottom flange is in the lee of, or sheltered by, the shed plate. The lading may thereby move under the influence of gravity past the shed plate to its desired unloading receptacle.

Abstract: The present invention discloses a two-level locking device, a hopper car bottom door and a hopper car. The device includes a first transmission shaft, a second transmission shaft, a clutch, a pressure mechanism and a reset mechanism, wherein under the pressure action of the pressure mechanism, the clutch separates the first transmission shaft from the second transmission shaft, and under the action of the reset mechanism, the clutch joints the first transmission shaft with the second transmission shaft. The bottom door includes the device. The hopper car includes the bottom door. By adopting the device, when the clutch is accidently separated by the pressure action of the pressure mechanism, the reset mechanism can re-joint the clutch to prevent the accidental rotation of the first transmission shaft and the second transmission shaft. By adopting the bottom door, the hopper car bottom door opened and closed by a planar four-bar linkage passing a dead point is more reliable to use.
