  • Patent number: 10550524
    Abstract: A beveled-end steel railroad. The use of small-acute-angle oblique-gap connection design and vertical gap reservation design can solve both the problem of impact between wheels and rails and the problem of thermal stress between steel rails. The design containing both beveled ends and flat ends that are complementary to each other can further greatly reduce railroad construction and reformation costs. The beveled-end steel railroad has a simple structure, is secure, reliable, and durable, can provide a fast, stable, and non-noisy driving effect, can implement highly-efficient and energy-saving operation, is easy to construct and reform, can be easily repaired and maintained, has a significant advantage in costs, and can implement both good performance and good profitability.

  • Patent number: 10138093
    Abstract: The passenger conveyor step flow adjusting apparatus includes: guiding pads that are disposed on two sides in a width direction of steps, and that contact facing wall surfaces of return path driving rails that are spaced apart in a width direction of a main frame, to suppress movement of the steps in the width direction; and a return path driving rail position adjusting portion that adjusts a position of each of the return path driving rails that are spaced apart in the width direction of the main frame in the width direction relative to rail supporting members.

  • Patent number: 9695555
    Abstract: The invention relates to a method to form a rail joint, in which staggerings (6, 7) corresponding to each other are made in joinable solid-profile rail ends (4, 5) of parts (2, 3) of a rail (1) so that when a completed rail joint is viewed from above the rail heads bond; both rail ends are secured to a corresponding mounting; the rail ends secured to the mountings are brought against each other whereby said bonding is established; and the mountings that are against each other are secured to one another. The staggerings (6, 7) are made in such a manner that the lower edges (4a, 5a) of the rail ends (4, 5) are left substantially unstaggered whereby the staggerings extend from these lower edges towards the top surfaces or the rail ends; and the rail ends (4, 5) are welded by their lower edges (4a, 5a) at their entire width to their mountings (8, 9). The invention also relates to a rail joint made by this method.

  • Patent number: 7289675
    Abstract: A scalable predictive coder in which the current frame of data is predicted at the enhancement-layer by processing and combining the reconstructed signal at: (i) the current base-layer (or lower layers) frame; and (ii) the previous enhancement-layer frame. The combining rule takes into account the compressed prediction error of the base-layer, and the parameters used for its compression.

  • Patent number: 5224575
    Abstract: A linear thermal expansion joint between two sections of power conductor rail formed of steel web and aluminum cladding about the web, each rail section longitudinally and vertically halved at the rail end through the center of the steel web creating a mating surface of selected expansion length. Each rail end includes an elongated slot and a guide block secured to the aluminum cladding and extending through the slot. The rail ends are slidingly secured together with bolts and spring washers on the guide blocks so that the rail ends overlap side by side with the mating surfaces facing each other sandwiching a brass slide plate which facilities longitudinal movement between the rail sections. Exposed ends of the rail contact surfaces are chamfered to eliminate snags or sharp surfaces and to compensate for small dimensional differences between rail sections during alignment and assembly of the expansion joint.

  • Patent number: 4702661
    Abstract: A robot carrier structure constituted by a portal wagon movable on rails and laterially supported by a pair of carriages each comprising a pair of wheels longitudinally coupled by motion transmission means actuated in synchronism by an electric motor. Further the two electric motors of the pair of carriages are so connected as to constitute an electric axis. Each wheel has a structure adapted to ensure a high adherence to the rail, particularly due to the provision of a pair of rings of elastomeric material engaging the rolling surface of the rail.

  • Patent number: 4381851
    Abstract: A track splice having finger members fixed to the spaced ends of two track sections. The finger members include adjoining, contacting surfaces which are configured to positively align the finger members and wheel support surfaces of the finger members and associated track sections, while enabling the ends of the track sections to be adjustably spaced. The track splice further includes a clamping device for firmly clamping the finger members together, once the desired spacing between the track ends is selected.
