A hopper car discharge section may be wide at the top and narrow at the bottom. Outflow is controlled by closure members, at least one of which is movable. The closure members come together to a closed condition or position for retaining lading. When apart, in an open position or condition, lading may be discharged. A seal member or seal member assembly is mounted to one or both of the closure members. The closure member may have a lading discharge encouragement feature, which may be in the nature of a tine, or blade, or knife that extends upwardly through the throat of the discharge section. Movement of the door may tend to move the blade, thereby tending to dislodge lading that may be otherwise reluctant to move.

A railroad hopper car discharge gate is assembled from unitary stacked frames that provide unimpeded flow of lading during discharge. A low-wear glide system minimizes friction between the gate panels and other components of the apparatus, and an improved sealing system protects lading from contaminants such as rain, dust and insect infestation and provides enhanced vacuum sealing for greater efficiency during vacuum discharge.

A low elevational profile of each of a pair of first and second wheel chocks for restraining a current “low-drag” motor vehicle in a carrier, such as a railway car, is derived from each wheel chock having an internally webbed, elongated stepped-box body terminated with a relatively short rectangular box having its inner wall integrally formed with the stepped-box body. The body of the first chock is essentially a mirror-image of the second chock body. The low profile of a wheel chock allows each to be positioned under a vehicle the rocker panel of which has its lower edge only 148 mm (5.82 inches) above the surface upon which the vehicle's tire rests, so that the installed chock height is reduced to 47.6 mm (1.87″) under the components of the vehicle's body. The assembly may include a pair of “active” chocks; or, one active chock and one anchor chock. A single window in the upper portion of the stepped-box provides access for a strap of a wheel harness, which strap is wrapped around a torque tube in an active chock. The torque tube in one chock is rotatable in a direction opposite to that of the torque tube of the other chock. With a pair of active chocks, hooks on straps of a prior art harness are eliminated because it is difficult and time-consuming to manipulate a tire harness with its straps and hooks to secure the tire between the wheel chocks. When one chock is an anchor chock, one end of the strap is provided with a hook which is anchored to a rod or tube which is substituted for the rotatable torque tube.

The invention relates to a transportation method and a package system for transporting a set of large longitudinal items such as blades for a wind turbine (1) or a tower for a wind turbine. Taking wind turbine blades (1) as an example, the advantages of the invention reside in packaging a tip (3) of one blade and a base (2) of a second blade in the one and same package (5) such that two blades (1) may be transported in packages (5, 16) having an overall lateral extension, approximately the same as the base of only one blade (1) for the wind turbine. Thereby a very compact but also a very easy means of transportation of large longitudinal items such as wind turbine blades (1) is provided.

The methods and apparatus for transporting compressed gas includes a gas storage system having a plurality of pipes connected by a manifold whereby the gas storage system is designed to operate in the range of the optimum compressibility factor for a given composition of gas. The pipe for the gas storage system is preferably large diameter pipe made of a high strength material whereby a low temperature is selected which can be withstood by the material of the pipe. Knowing the compressibility factor of the gas, the temperature, and the diameter of the pipe, the wall thickness of the pipe is calculated for the pressure range of the gas at the selected temperature. The gas storage system may either be modular or be part of the structure of a vehicle for transporting the gas. The gas storage system further includes enclosing the pipes in an enclosure having a nitrogen atmosphere. A displacement fluid may be used to offload the gas from the gas storage system. A vehicle with the gas storage system designed for a particular composition gas produced at a given location is used to transport gas from that producing location to a receiving station miles from the producing location.

A method and system using a compressed display mode list is disclosed. In particular, the compressed display mode list includes a plurality of data representing the display modes.

The Personal Mass Transit (PMT) system utilizes a removable vehicle conveyance apparatus and method for conveying transit vehicle car-pods and their contents from one transit station to another autonomously. Vehicle conveyance apparatus are stored off-line in storage silos and other areas awaiting on-demand transit system instruction to pickup vehicles at loading points and convey them to different stations as requested by occupants or pre-programmed instructions. The PMT system further utilizes a number of transmitter-receivers nodes and control computers to manage all aspects of operation of the transportation system. Any number of different types of PMT vehicles could ride the transit system when equipped with the correct coupling points and remain under the maximum combined curb weight of any particular area or type of transit track in order to be transported on the PMT system.
