  • Patent number: 10926781
    Abstract: Support frames and rail cars include first and second side drive plates, first and second cross members connecting the respective ends of the side drive plates, third and fourth cross members connecting the side drive plates at a select distance from the first and second cross members, a coupling assembly situated at the first cross member and adapted to connect another rail car thereto, and first and second diagonal support members connected to the first cross member at an angle sufficient to substantially direct forces from the coupling assembly to the third cross member and side drive plates. The support frames and rail cars may be used for conveying bulk materials on a rail transport system.

  • Patent number: 10583846
    Abstract: The present invention generally relates to a rail transport system having no internal drive, and in particular to an improved rail transport system for conveying bulk materials. The rail transport system includes horizontal and vertical drive stations that include a drive tire that rotates on a plane parallel to the track. In this arrangement, force is applied on a different plane than earlier systems, and the reaction force is separated out of the tensioning device. The improvements of the drive stations provide for a reduction of steel used in the system, improved manufacturability and, therefore, reduction in system component costs as compared to previous drive stations. Moreover, the drive stations allow for improved maintainability and access to the drive tires.

  • Publication number: 20180186384
    Abstract: Systems and methods for sensing a train position of a train with no internal drive operating in an automated train system are provided. According to one embodiment, a train system comprises a track extending in a travel direction, a plurality of cars riding on the track and connected to form a train, a position sensing unit, and a programmable logic controller (PLC) in signal communication with the position sensing unit and configured to determine a train position based on inputs therefrom.

  • Publication number: 20180127003
    Abstract: The present invention generally relates to a rail transport system having no internal drive, and in particular to an improved rail transport system for conveying bulk materials. The rail transport system includes improvements in functionality, manufacturability and/or modularity and, therefore, can result in a reduction in system component costs, manpower and/or implementation. The rail transport system includes a dump loop and components thereof for enabling unloading of the rail cars in a predetermined location. The components thereof may be designed to be modular to allow for ease of manufacture and installation of the dump loop. The components may be prefabricated for later use on site.

  • Patent number: 8186362
    Abstract: A concave finger nail file includes a retention base and an abrasive surface. The retention base may have any suitable shape, such as a cube, a cylinder or a D-shaped tube. The retention base may be solid or hollowed-out. A concave cavity is formed in a top of the retention base. The abrasive surface is applied to the concave cavity. The abrasive surface may also be applied to a bottom or to a side wall of the retention base. The retention base is held between a forefinger and thumb of one hand; a finger or thumb of the other hand is inserted into the concave cavity; and the retention base is pivoted about the finger or thumb of the other hand to file the end of a nail. A second embodiment of the concave finger nail file includes a removable peel and stick abrasive surface.

  • Publication number: 20110078604
    Abstract: An apparatus for reporting an alert state at any level of a hierarchy of managed objects in a computing system includes an arrange module that arranges the managed objects in a hierarchy. The hierarchy includes a top view and at least one sub-view, wherein the top view visually indicates an alert state representing the highest alert state of all managed objects and sub-views under the top view. A method for reporting an alert state at any level of a hierarchy of managed objects in a computing system includes arranging the managed objects in a hierarchy, having a top view and at least one sub-view, wherein the top view visually indicates an alert state representing the highest alert state of all managed objects and sub-views under the top view. A user display window for displaying an alert state at any level of a hierarchy of managed objects includes a navigation pane, a display pane, and a detail pane.

  • Patent number: 6733634
    Abstract: An improved system, apparatus and method is disclosed for transferring a running web from a first carrier fabric to a second carrier fabric in the manufacture of webbed products, such as tissue, paper toweling, and the like. A multi-stage vacuum process applies a vacuum to the running web. One or more auxiliary units apply a vacuum to one or more edge portions of the running web. The apparatus provides for a reliable and efficient transfer of the running web among carrier fabrics, in which the carrier fabrics may include topographical features upon their surface.
