Abstract: Provided is a negative electrode plate, comprising: a negative electrode current collector and a first negative electrode active material layer. The first negative electrode active material layer is arranged on at least one surface of the negative electrode current collector, wherein, components of the first negative electrode active material layer comprise, by mass: 30%-70% of a silicon-based material, 15%-40% of a binder and 15%-40% of a conductive agent.

Abstract: A symmetrical multi-unit railroad freight car, such as a 3-pack railroad intermodal well car, has body units that are connected symmetrically. The body units have a symmetrical arrangement of end trucks and shared trucks. The end trucks are 70 Ton Trucks. The shared trucks are 125 Ton trucks. The trucks have passive steering using geometric rocker stiffnesses. The rockers in the end trucks have a smaller radius of curvature than the rockers in the shared trucks. The spring groups in the shared trucks are stiffer than the spring groups in the end trucks. The spring groups in the end trucks have a different proportion of damping when empty, a shorter live load range of travel, and greater reserve travel than the shared trucks. The end trucks and the shared trucks have four-cornered damper groups that have the same sized damper wedges. The damper wedges have non-metallic wear pads.

Abstract: A railroad hopper car has a hopper carried between two trucks, and has convergent end and side slope sheets that feed a bottom discharge. The bottom discharge has a rectangular frame. The bottom discharge is lower than the center sill. The car has a flat bottom discharge having multiple arrays of louvers. All of the lading discharges through the flat bottom. The side sheets extend downwardly beyond the side sills, so that the side slope sheets terminate below the side sills. The car has laterally extending shear force transfer members, that provide a shear connection between the side walls of the car, and have openings to permit lading from the main containment volume of the car to pass therethough to the lading discharges. The louvers are joined to move together. Alternatively, the gate may include two opposed sliding doors separated by a beam that runs under the center sill.

Abstract: A railroad hopper car has a hopper carried between two trucks. The hopper has convergent end and side slope sheets that feed a flat bottom discharge. It has a rectangular frame at least half as wide as the car, and at least half as great as the truck center distance. The car capacity is over 5000 cu. ft. The bottom discharge is lower than the center sill. There are ring frames having a bottom reinforcement that passes clear under the center sill. The car has flat bottom discharge gates having multiple arrays of louvers. The side sheets extend downwardly beyond the side sills, so that the side slope sheets terminate at a transition below the side sills. The louvers have curved edges. The louvers move together. The gate may include two opposed sliding doors separated by a beam that runs under the center sill.

Abstract: An improved mechanism for evaluation of degradation criticality is described. Corresponding apparatuses, systems, methods, and computer readable media are provided. The evaluation of corrosion criticality is utilized to estimate a failure pressure of a pipeline that is subject to structural degradation (e.g., metal loss corrosion). The evaluation, in some embodiments, is utilized with a specific tool configured for controlling or otherwise regulate pipeline operations responsive to the estimated failure pressure. The evaluation is a specific technical process whereby multiple failure paths through anomalies (structural defects arising from degradation features) are utilized in concert to determine an estimated failure pressure. The failure pressure, in some embodiments, is used to control actuation of one or more valve regulator features or to guide excavation.
