  • Patent number: 8201735
    Abstract: Electronic delivery of counterfeit-resistant documents exchangeable for value such as admission tickets, gift certificates, coupons, vouchers, etc. directly to the person who ordered the documents over an open communications network such at the Internet. A first party orders a document from a second party, and the second party electronically delivers the ordered, counterfeit-resistant document to a device designated by the first party. For example, the document may be electronically ordered using a PC, and a printer coupled to the PC may print the document. In one embodiment, the first party transmits unsolicited offers over the open communications network The document may be made counterfeit resistant by assigning unique information to each document of a given type, e.g., admission tickets, and checking the uniqueness of a document and whether the unique information was previously read prior to allowing it to be exchanged for value.

  • Patent number: 6068195
    Abstract: A railway crossing structure for a railway track including an elastomeric gauge insert (50) fitting between each rail (10) and the adjacent gauge panel (12). Elastomeric gauge insert (50) has a body portion (70) formed by upper and outer sides (72, 74) separated by an elasticity cavity (76) and joined to each other at juncture (78) defining an outer sealing surface (80). Hinge lines formed by notches (82, 84) in sides (72, 74) assist in the folding or flexing of body portion (70) as shown in FIG. 6 during installation of gauge insert (50) by a pushing force exerted against upper surface (62) of body (52). Body portion (70) snaps beneath head (16) of rail (10) upon the seating of gauge insert (50) with leg (54) engaging arcuate connecting surface (36) of base (18) as shown in FIG. 3. Sealing surface (80) of body portion (70) seals against undersurface (30) along a relatively large sealing area and a relatively large sealing force is provided by compressed sides (72, 74).

  • Patent number: 4606498
    Abstract: The invention provides a seal for rails in a road level railbed comprising inner and outer resiliently flexible elongate members secured about each rail. The seal members are contoured to fit snugly against the inner and outer sides of a rail and are provided with a flexible membrane accommodating rail spike heads. The inner members have a groove to allow clearance of the flange of a railcar wheel and a flexible membrane extends beneath the groove. Movement of the flexible membrane in response to the railcar wheel flange breaks up silt and detritus which has a tendency to settle and pack hard in the flange groove. The movement of the flexible membrane also allows for deicing in the winter.

  • Patent number: 4461421
    Abstract: The present invention contemplates a resilient pad mounted on the outside adjacent portion of a rail having sealing engagement with the rail along its base, the head and the interconnecting web of the rail with compression chambers located within the pad to permit the resiliency of the pad to cooperate with the movement of the rail in its vertical displacement as well as other movements imparted thereto by the passage of trains, thereover while maintaining a sealing contact with the rail to prevent water collecting along the rail and other foreign matter to minimize maintenance.

  • Patent number: 4203547
    Abstract: A railway level crossing (grade crossing) is described in which the road surface between the rails is, at least adjacent the rails, provided by flexible plates, e.g. rubber plates. The plates extend right to the rails and under their edge portions adjacent the rails are resilient support means which allow the plate to flex downwardly when engaged by the flange of a wheel passing on the rail. The resilient support may be a gas-filled tube extending parallel to the rail.
