摘要： Cellulose nanofibers (CNF) act as a dispersing agent to directly exfoliate graphite in an aqueous solution using sonication. The resulting suspension has graphite flakes, each having 2-20 monolayers, a relatively large lateral dimension, and a plurality of CNF decorating its surfaces and edges. The dispersing effect of the CNF allows the graphite-CNF suspension to be stored without degradation until desired use. The graphite-CNF suspension can be used to form various composite structures, such as by spraying, coating, pouring, extruding, or printing the suspension, and then drying the suspension. The resulting composite structures have improved tensile strength and toughness due to hydrogen bond interactions between the CNF and graphite.

摘要： An IBC storage box assembly is elevated from a railcar. A vertical beam is used to elevate the storage box off the railcar so that the storage box is more easily accessed from a rail platform. Additionally, the vertical beam may provide some clearance for the storage box so that the storage box is not impacted by the railcar coupler during transport.

摘要： According to some embodiments, a railcar comprises at least two hoppers for transporting a commodity. Each hopper comprises a pair of side walls and a floor. The railcar further comprises a composite partition separating the hoppers. The composite partition comprises a frame comprising a first material coupled to the pair of side walls and the floor at a location separating hoppers. The frame comprises a center opening. The frame is configured to provide structural support for structural loads exerted on the pair of side walls and the floor. The composite partition further comprises a composite section comprising a second material coupled to the frame and covering the central opening of the frame. The composite section is configured to withstand loads exerted on the composite section by the commodity transported in the hoppers.

摘要： According to some embodiments, a discharge door locking system for a railcar discharge door comprises a lock piston configured to move between a first position (not engaged with an operating beam coupled to a discharge door) and a second position (engaged). The locking system comprises a first and second input. Activation of the first input moves the lock piston to the first position, and activation of the second input moves the lock piston to the second position. The first input of the locking system is coupled to a first input of an operating cylinder coupled to the operating beam. The first input of the operating cylinder is configured to move the discharge door to the open position.

摘要： According to some embodiments, a refrigerated railcar comprises a pair of side walls, a roof, a floor, and a refrigeration unit. The floor comprises a bottom structure comprising a plurality of channels for return air flow from an interior of the railcar to the refrigeration unit. The floor further comprises at least two top plates coupled to the bottom structure (e.g., via a pivot rod). Each of the top plates extends longitudinally along the bottom structure and is configured to rotate up and away from the bottom structure proximate one of the side walls of the pair of side walls. Lifting an edge of a top plate opposite the edge of the top plate pivotally coupled to the bottom structure causes the top plate to rotate to an upright position exposing the plurality of channels of the bottom structure.

摘要： A railcar comprises a first end, a second end, and a first longitudinal side and a second longitudinal side disposed between the first end and the second end. The first longitudinal side comprises a center panel and an intermediate panel. The center panel is disposed between a center of the railcar and the intermediate panel. The intermediate panel is disposed between the center panel and the first end or the second end. A width of the railcar at the intermediate panel is greater than a width of the railcar at the center panel. The center panel and the intermediate panel comprise generally straight panels coupled together at an angle. The first longitudinal side may further comprise an end panel disposed between the intermediate panel and the first end or the second end.
