20100170955 | Concrete Tie Fastener - This invention addresses issue of rail seat abrasion by completely removing all elastomers from directly contacting the rail by utilizing a shoulder post with a lower portion that is coated or encapsulated with a nonconductive material and a rolled or cast tie plate design that introduces a tie plate to the rail seat of the concrete tie. The coated or encapsulated lower portion of the shoulder is then cast into the concrete. By having the pad between the plate and the tie, it is subjected to vertical compression only with no rubbing action. | 07-08-2010 |
20100219256 | MAGNETIC RAIL BOND - Magnetic means and apparatus for implementing rail bonds and rail feeds. A rail bond embodiment comprises an electrical conductor. Mechanically and electrically coupled to each end of the electrical conductor is a magnet that comprises a magnetic material that is plated with an electrically conductive material. In an alternative embodiment, the magnet comprises a magnetic material that is disposed between two pieces of steel or other metal. In operation, the two magnets are attached to two rail sections, across a joint separating the rails, via the attractive magnetic force between each magnet and its associated rail. In this way, the electrical circuit comprising the rails is maintained. | 09-02-2010 |
20120261482 | TRACK FOR A TRACK BOUND VEHICLE - A track for track bound vehicles, in particular for light rail vehicles. Includes a support element for supporting an electric conductor arrangement, which is adapted to produce an alternating electromagnetic field and—thereby—to transfer electromagnetic energy vehicle on the track. The support element confines spaces for receiving lines and/or wires of the conductor arrangement. An electrically conductive shield for shielding the alternating electromagnetic field extends along a plane below the spaces. A housing for receiving a power supply device for supplying electric power to the conductor arrangement is also provided. | 10-18-2012 |

20100187322 | STRIKE ATTACHMENT RAILROAD SIGNAL LINE CONNECTOR - A system and method for non-invasively attaching components to railroad track rails. More specifically, a connector is provided that can quickly and effectively electrically connect one or more signal lines with a surface of the track rail. In one embodiment, the non-invasive connector utilizes a spring clamp to form an electrical connection with a flange portion of the track rail. First and second opposing members of the spring clamp include teeth that mar the surface of the flange to form an electrical connection between the track rail and the spring clamp when the flange is forced between these opposing members. A signal line is electrically connected to the spring clamp. | 07-29-2010 |
20160040364 | RAILWAY SLEEPER COMPOSED OF FIBRE-REINFORCED STONEWARE - The invention describes a new type of railway sleeper composed of fiber-stabilized stoneware. By using a plurality of fiber-layered stone plates which are bonded to one another in such a way that prestress is generated in the stoneware, a permanently high-performance-capable sleeper is obtained, which is made of natural materials such as granite or basalt which occur almost everywhere on the earth in unlimited quantities and have a substantially longer service life and are substantially more resistant to influences of the weather and the environment than previous solutions. The material can be manufactured with substantially less consumption of energy than current systems. As a result, in the medium term, CO | 02-11-2016 |

20160090009 | RAIL BOND - A rail bond which achieves high durability and high reliability in response to vibration caused by running of trains is provided. [Solving Means] A rail bond according to the present invention includes a conductor that electrically connects rails separately adjacent to each other, terminals electrically connected to the conductor and welded on side surfaces of the rails, and end-edges at which the conductor is connected to the terminals. Each of the terminals has a welding region welded on the side surface of the rail, and, in a direction almost perpendicular to the side surface of the rail, the welding region, the terminal, the end-edge, and the conductor have a predetermined relationship with respect to at least one of positions, mutual shapes, lamination, and a lamination structure. | 03-31-2016 |
