  • Patent number: 11001973
    Abstract: A gauge spacing apparatus for positioning pot sleepers with respect to existing sleepers of a railway track has a pair of turnout rails, which are separated from one another by a desired gauge distance. The gauge spacing apparatus includes a first guide member aligned with and secured with respect to a portion of the existing rail; and a second guide member angled with respect to the first guide member at a turnout angle. The second guide member is aligned with a portion of a turnout rail to allow the turnout rail to be provided with supporting pot sleepers, such that the desired gauge between the turnout rails is maintained. Also provided are a rectangular gauge spacing apparatus, a shear plate arrangement for providing supported engagement between first and second sections of rail, and a support framework for supporting a planar supporting member spanning over an existing rail.

    Abstract: A system for selecting digital content from at least one content source employs a plurality of RFID enabled objects that are read by one or more RFID readers. The RFID enabled objects may be, for example, RFID enabled media objects or RFID enabled non-media objects, such as any suitable RFID enabled object. Specific combinations of RFID tags and RFID enabled objects, or RFID enabled media objects provide access to more (or different) digital content than the same tags provide alone. A method includes contactlessly reading a plurality of RFID tags associated with a plurality of RFID enabled objects to obtain a plurality of RFID tag information and determining whether each of the read plurality of RFID tag information has been read within a suitable time period with respect to each other. If so, the method includes sending the read plurality of RFID tag information for receipt by a content delivery authorization unit to determine if downloadable content is available for download.
