  • Patent number: 7793891
    Abstract: A modular railway diamond crossing incorporates sets of acute and obtuse angle castings. The rail connections to the castings have a fine taper to minimize joint impacts. The castings are spaced apart with a combination of rails and cast blocks. The outside block is a tapered design that maintains the flangeway and holds the castings and rails together. The inside block comprises a tapered common center casting. This unit also maintains the flangeway and a longitudinal distance between the castings. The center casting is a common part to all such crossings regardless of the crossing angle.

  • Patent number: 6971610
    Abstract: A railway crossing has a plate with a pocket that defines a crossing angle for enabling one railway line to cross over another at virtually any angle. The pocket closely receives continuous long beams and divided beams. The pocket also has protrusions for restricting longitudinal horizontal movement of the beams. Each divided beam has three separate, discontinuous segments, including two outer segments and one inner segment. The segments are reversible such that the inner segments may be interchangeably positioned with each other, and the outer segments may be interchangeably positioned with each other. Fasteners secure the beams to the plate and resist both vertical movement and lateral horizontal movement. Each fastener has a wedge brace, a clip, and a wedge. The wedge prevents pull-apart of the plate and the beams due to thermal forces, mechanical forces, and surface discontinuities.

  • Patent number: 6276643
    Abstract: The strength and reliability of railroad, track structures, such as frogs, crossings, and guardrails, is enhanced. Filler members and filler blocks are fitted in to support and strengthen the structures. The filler members and filler blocks provide better matching and alignment of load transfer surfaces. The track structures with the improved components are more easy to align and assemble. The strength of the assembled track and structures is also increased, and the structures are more easily maintained.

  • Patent number: 5957055
    Abstract: A container-transporting system with tracks, linear motors and rotatable wheels. The system includes a network of tracks which are arranged transversely at right angles with respect to one another and parallel to one another and form points of intersection. Guide rails are arranged in the tracks outside the points of intersection and have track-bound transporting carriages moving on them by way of running wheels which can be turned about a pivot spindle. The distances between the running wheels correspond to the distances between the tracks. The running wheels, which are enclosed by horizontal guide rollers, can be rotated in the points of intersection. Magnets are arranged on the transporting carriage in the longitudinal and transverse directions and, by way of stators of the track, move the transporting carriage in the longitudinal and transverse directions. Pivoting slides, which are arranged on the transporting carriage, turn the running rollers.

  • Patent number: 5845881
    Abstract: A railroad trackwork intersection assembly such as a crossing intersection or a turnout intersection is provided with at least one flange-bearing frog subassembly which has railcar wheel flangeways of uniform depth throughout the frog planform that co-operate with trackwork traffic rails, with easer subassemblies that are positioned exterior to but abut the frog subassembly, that have sloping flange support surfaces, and that may be removed from or adjusted in the assembly without moving or adjusting either the frog subassembly or the co-operating trackwork traffic rails.

  • Patent number: 5797565
    Abstract: A railway crossing, sometimes referred to as a diamond crossing, has four substantially identical crossing beams which have cutouts made for a wide range of crossing angles. At least two separate base plates are cut to fit the required crossing angle and positioned beneath the crossing beams. Each crossing beam has a flangeway groove extending along at least a portion of the beam length and each beam has integral rail shaped ends for connection to a standard rail section. The crossing beams have top cutouts and bottom cutouts that intersect and are set for a predetermined crossing angle. Boltless locator pins prevent horizontal movement of the top and bottom beams on the plates, and elastic fasteners hold the top and bottom beams to the plates to restrict vertical movement between the top and bottom beams and the plates.

  • Patent number: 5765785
    Abstract: An improved standard crossing for railroad track is provided, having an interchangeable insert. The interchangeable insert permits easy changing of the most commonly worn pieces in situ, and avoids the expense of having to remove and replace the entire crossing when only parts of it are worn or broken. A filler member for fitting in to support and strengthen the crossing, as well as turnouts and other railroad structures, is also provided. The filler member makes it easy to align and assemble the structure, while also supporting the head portion of the rail.

  • Patent number: 4825772
    Abstract: A pouring tank assembly and transfer tracks are provided whereby a transfer car holding a pouring tank filled with molten metal can be rolled from a loading station to a pouring station. The transfer tracks are of a double rail configuration, with two tracks forming an angle whose vertex is at the pouring station. A third guide rail parallels each set of tracks. The transfer car is equipped with flangeless wheels which roll along the transfer tracks, and has a support arm from which guide rollers extend. Such guide rollers contact the guide rail to provide lateral stability for the transfer car.

  • Patent number: 4352895
    Abstract: The present invention provides a process for the continuous production of plates, which are optionally laminated on all sides, from foamed synthetic resins and especially from polyurethane hard foams, in which a foaming synthetic resin is passed through a channel formed by endless running bands, wherein the side bands are subjected to external pressure and press towards the middle of the plate, said side bands being pressed in the course of the foaming by the foaming pressure thereby arising into their actual side-limiting positions, said side bands finally assuming the positions which correspond to the desired plate breadth and contour.The present invention also provides a device for taking up the lateral foam pressure in continuously operating band plants, comprising counterpressure devices which exert on the side bands, adapted to move in the plane of the plate, an optimum counterpressure for the reaction characteristics of the foaming synthetic resin.
