摘要： Apparatus is disclosed for assisting in the unloading of a difficult to unload lading from a vessel. An accumulator is mounted adjacent the vessel. A first conduit connects the accumulator with a valve for periodic discharge of the accumulator. A self-indexing elbow is rotatably mounted on the vessel and extends within the vessel. A second conduit connects the valve with the elbow. The elbow includes an elbow conduit portion in fluid communication with the second conduit. The elbow conduit portion has a center line defining an axis about which the elbow is rotatable. The elbow also includes an elbow portion having an elbow center line passing therethrough. The elbow portion has a discharge end having a discharge opening through which the elbow center line passes. At the discharge end the elbow center line is offset with respect to the axis so as to define a moment arm between the elbow portion and the axis. The accumulator is pressurized with gas sufficient to dislodge bridged or clogged lading in the vessel and sufficient to cause said elbow to rotate relative to the axis. A bearing assembly is mounted between the elbow conduit portion and the vessel, having a frictional force sufficient to limit rotation of said elbow with respect to the vessel, such that rotation ceases at a new angular position relative to the axis prior to the next discharge of pressurized gas from the accumulator. The elbow may be attached so that the frictional force can be adjusted to vary the extent of elbow rotation after each blast of gas is discharged from the elbow. A check valve may be applied to the discharge end of the elbow to prevent lading from entering the elbow. Lading clearing openings in addition to the discharge opening may be provided in the elbow portion to facilitate removal of lading or other material which may tend to hold the elbow in place and prevent the same from rotating as a blast of gas is discharged from the discharge opening.

摘要： A vacuum relief valve assembly includes a vacuum valve member located below a top cover plate and is thus protected from the atmosphere. First passageways defined in part by a bottom cover plate provide communication between the outside atmosphere and the lower surface of the valve. Second passageways provide communication between the upper surface of the valve and the inside of the container. When the pressure in the container is below atmospheric, atmospheric pressure acting on the bottom of the valve lifts the valve and air flows through the first and second passageways until atmospheric pressure is reached in the tank. A pressure relief valve is mounted for pivotal movement relative to an opening providing communication between the pressure in the tank and the first passageways to vent pressure in the tank. The pressure relief valve is protected from the atmosphere by the top cover plate, and in one embodiment, by the vacuum relief valve.

摘要： A railway hopper car (H) has a bottom outlet (B). An outlet assembly (A) is attached to the outlet for lading to be discharged into the outlet. An outlet flange (OF) at the bottom of the hopper defines the lading discharge outlet. A mating flange (F1) is formed on the outlet assembly for attaching the outlet assembly to the railcar. Fasteners (L) are used to mount the outlet assembly to the hopper bottom. A gasket (3) installed between the respective flanges effects a seal between the hopper outlet and outlet assembly. The gasket extends circumferentially about the opening. One of the flanges has a circumferential groove (9) and the gasket has a raised portion (15) extending circumferentially of the gasket and sized to be received in the groove. This arrangement aligns the gasket with the flanges so when the outlet assembly is mounted to the bottom of the hopper, no cavities are formed in the between the hopper outlet and the outlet assembly. Similarly, an end adapter (E1, E2) is attached to the ends of the outlet assembly. A second gasket (5) is used to effect a seal between the adapter and outlet assembly. A groove (23) is formed in an outlet assembly flange (F2) to which an end adapter flange (MF) mates, and the gasket has a raised portion (25) fitting in the groove also align the gasket.

摘要： A hopper is provided having longitudinally spaced tapered end walls and transversely spaced tapered side walls. An opening is provided in one of the end walls and a discharge conduit is attached to the external surface of this end wall. On the internal surface of this end wall a discharge trough is attached. The front surface of the trough is tapered on the same incline as this end wall. Fluidizing membrane assemblies are attached to each of the side walls which are inclined downwardly toward the discharge conduit to facilitate lading flowing into the discharge conduit during unloading. The discharge trough is generally in the form of an inverted V, with the lower edges of the V spaced from the lower hopper wall a distance sufficient to allow air and lading to pass around the trough and into the discharge trough. The lower edges of the V are preferably tapered inwardly and downwardly toward the end wall to increase the velocity of the fluidized lading as it passes into the trough and then into the discharge conduit.

摘要： A pair of longitudinally spaced valve elements are provided in a pneumatic outlet. Each valve element includes a body portion, preferably a segment of a circle, including a body portion edge which seats on a body portion valve seat located adjacent the body portion edge, and a moment portion extending eccentrically away from the body portion, which seats on a moment portion valve seat. Each valve element is movable to a sampling position in which the body portion is spaced from the body portion valve seat and the moment portion is spaced from the moment portion valve seat to allow lading for sampling to flow into the discharge conduit. Each valve element includes a pair of operating shafts extending in opposite directions from the valve element, parallel to the discharge conduit, through opposite end walls of the outlet. Operating handles are attached to the operating shafts outside the end walls of the outlet. The discharge conduit end caps are held in place with a pair of large headed bolts which are pivotably mounted on the discharge conduit and which engage at least a portion of the adjacent end cap. The large headed bolts are attached to vertically extending locking members of generally inverted J shape which are rotatably mounted on a side of the discharge conduit. In accordance with the present invention, the lower locking surface on a pair of diagonally spaced inverted J bolts is spaced from its respective operating handle a distance sufficient that if the end cap on the near or sampling end of the outlet is removed, the operating handle on the sampling end may be rotated sufficiently to move the valve member away from its valve seat a distance sufficient to take a sample of lading, without removing the end cap on the opposite end of the discharge conduit.
