  • Patent number: 9752285
    Abstract: The sleeper block unit (1) for railway track systems consists of a sleeper block (2) and of a sleeper shoe (3) that partly surrounds the sleeper block (2). The sleeper block (2) has a head portion (4) and a base portion (6), the head portion (4) extending beyond the base portion (6) in length and in width, thus forming a step (10). At the upper edge of the sleeper shoe (3), a surrounding, upwardly and outwardly extending sealing lip (14) that lies against the step (10) is arranged. As a result, during vertical movements of the sleeper block (2) in the sleeper shoe (3), the sealing lip (14) is deformed substantially vertically in the elastic range rather than rubbing against an outer wall of the sleeper block as in known sleeper block units. In this manner the sealing lip is subject to reduced wear so that the sealing effect is maintained for a longer period and the sleeper block unit (1) has a longer lifetime.

  • Patent number: 6323441
    Abstract: An ultrasonic distance measuring system for monitoring railroad car loads. The system includes an ultrasonic transducer, a pulse generation and detection circuit and a measurement circuit. The transducer produces a transmitted ultrasonic pulse beam to be directed at a load in a railroad car and receives a return pulse beam from the load. The pulse generation and detection circuit is coupled to the transducer and causes the transducer to produce the transmitted pulse beam. A return pulse beam is detected by the pulse generation and detection circuit. The measurement circuit is coupled to the pulse generation and detection circuit and generates a measurement signal representative of the load as a function of the time delay between the transmitted and return pulse beams.

  • Publication number: 20010028001
    Abstract: A method of making a polymer coated rail in which a rail to be coated (10) is positioned on a mould base (11) in an inverted manner, so that the head (12) of the rail is immediately adjacent the base plate (11). Then, mould side pieces (13, 14) are secured to the base plate (11) to run parallel to the side of the rail (10). Antislip material such as bauxite or granite chippings (21) are positioned in the mould so that they lie on the base plate (11), and then the liquid polymer is poured into the mould to fill the spaces (19, 20) and so encapsulate the rail (10). The polymer is poured into the mould, until its surface (22) covers the foot (23) of the rail. In this state, the polymer is allowed to cure, so that it solidifies, and once the side plates (13, 14) have been removed, the rail together with its polymer coating can be lifted from the base plate (11).

  • Patent number: 5238734
    Abstract: This invention relates to the use of rubber fragments from discarded tires in railroad ties. Such ties are made using rubber fragments which contain steel, polyester, or other strands or fibers, and which therefor are less expensive to prepare than fragments from which the reinforcing strands have been removed. These fragments are mixed with an epoxy mixture comprising an oxirane-containing resin and an amine-containing hardening agent. Test samples made using the materials described herein have excellent hardness, strength, durability, and nail-gripping characteristics.

  • Patent number: 4781875
    Abstract: Prestressed concrete railroad ties are formed in molds which are supported by existing track near the area where they are to be installed. Each mold will form a number of ties. Reinforcing strands are located within a plurality of longitudinally spaced molds. Concrete is then poured into the molds and the ties are formed bottoms up in the molds. A group of ties are simultaneously removed from a given mold by a special extractor which first simultaneously clamps the reinforcing strands extending outwardly from a given mold, and then lifts the strands as a group from the mold by a suitable crane. Preferably the center of gravity of ties is spaced from a pivot point which will cause 180.degree. rotation locating the ties in upright position to be loaded on a railway car or other vehicle to take them to the site where they are to be installed.

  • Patent number: 4469277
    Abstract: A back-up guide for trucks or trailers is made of two elongated members attached perpendicularly to each other, with spikes on their underside to hold the device in a stationary position. The longer of the two members provides a guide for the side of a vehicle's rear wheel during backing up, and the other, shorter, member is laterally disposed and provides a wheel chock or stop member for the rear wheel, and also acts as a visual stop point for the driver. The lateral member has a rearward extension near each of its ends, which provides supports for wheels which allow easy movement of the device when the front end is raised to lift the spikes clear of the ground. Both members may be equipped with handles for ease of handling.

  • Patent number: 4265398
    Abstract: A variable thickness fabric mat for use in railroad track structures, and particularly at stress transition zones in the railroad track; the mat is preferably formed of non-woven, multi-layered fabric, with the layers connected together, as for instance by needle punching to form an integral member. The mats are applicable for use with poor load bearing soils, and form a generally stepped, resilient bed for conventional railroad track structure, to help support and progressively spread the stress from the wheeled traffic, over a wider area. The mats provide for effective passing of runoff water, and aid in drainage of water from the soil beneath the mats, to thus improve the track support. The invention also provides a method of forming a railroad track construction so as to spread the stress from wheeled traffic at stress transition zones, over wider areas.
