Conduit, Third Rail Or Trolley Patents (Class 246/419)
  • Patent number: 6025702
    Abstract: A signal processing unit for a controller of a trolley pole switch is disclosed. The trolley pole switch switches the path of travel that an energy collector takes through the switch at a junction of catenaries at which a turn catenary and a straight catenary diverge from the straight catenary. The signal processing unit includes an input stage, a detection stage, turn and straight signal demodulation stages and an output stage. The input stage conditions modulated signals, each of which indicating a request to switch the path of travel through the trolley pole switch to the desired catenary diverging therefrom. The detection stage generates a validation signal if the conditioned modulated signal falls within a predetermined band. If the turn demodulation stage receives a conditioned modulated turn signal from the input stage and the validation signal from the detection stage simultaneously, it generates a low logic signal.

  • Patent number: 5740025
    Abstract: An electronic controller for controlling a trolley pole switch is disclosed. The trolley pole switch switches the path of travel that an energy collector of a trolley pole takes through the trolley pole switch at a junction of power conduits diverging from the trolley pole switch. The electronic trolley pole switch controller includes a signal processing device and a power controlling device employed in tandem to control the frog solenoids of a trolley pole switch. The signal processing device detects and processes a plurality of modulated signals. Each modulated signal represents a request to switch the path of travel that the energy collector takes through the trolley pole switch to a desired one of the power conduits diverging therefrom.

  • Patent number: 5691888
    Abstract: A power controlling unit for use with a radio board of a trolley pole switch controller is disclosed. The trolley pole switch has at least one frog for switching the path of travel that an energy collector takes through a junction of catenaries. The power controlling unit includes three reduction stages, a chopper control stage, and two output stages. A first reduction stage reduces power received from one catenary to an initial power level. The chopper control stage outputs two pairs of alternating signals. Controlled by a first pair of alternating signals, a second reduction stage reduces the initial power level to a secondary power level to operate the radio board. As long as it receives the initial power level, the third reduction stage reduces the secondary power level to a primary power level to operate the power controlling unit.

  • Patent number: 4970964
    Abstract: A single turnout rotary guideway switch is provided with an elongated structural frame member having guidebeam, electric rail and tire path structure on each of two sides of the switch compatible with the guidebeam, electric rail and tire path structure of the guideway. Switching is achieved by rotating a movable part of the switch 180 degrees about its longitudinal axis. One elongated beam acts as a principal structural member of the frame and provides a tire path on one of the switch sides for main line car routing by the switch. Another curved beam is secured between the one beam and another elongated beam that extends generally parallel to the one beam. The curved beam cross-supports the frame and provides a tire path on the other switch side for car turnout routing by the switch. In a crossover switching station in a dual lane guideway, a pair of the single turnout rotary switches are combined with an interface guideway section to provide for lane-crossover car routing by the switches.

  • Patent number: 4969400
    Abstract: A tire path, guidebeam, electric rail configuration for a guideway in a people mover system comprises a roadway structure having a pair of spaced tire paths forming a vehicle running surface. A guidebeam is disposed along a centerline between the tire paths to provide generally vertical guidance surfaces above the tire running surface for generally horizontal guidewheels on the vehicles. First and second electric rail units are substantially identically structure and extend along the roadway structure between the tire paths to provide conductive surfaces above the tire running surface for electric collection by brush assemblies on the vehicles. Together, the electric rail units have a predetermined number of electric rails to provide power and signal circuits for the vehicles. The first and second electric rail units are supported on opposite sides of the tire path centerline and at substantially equal distances from the centerline to enable turnaround vehicle operation.

  • Patent number: 4774891
    Abstract: Cargo and passenger vehicles are pneumatically propelled by a system comprising a bifurcated rail module assembled on a beam, for establishing two alternative routes for the rail network, according to a position adopted by line changing equipment. Switch points in the rails are synchronized by an actuator located below the beam, the motion of which is transmitted by torque tubes that drive the switch points. The control motion of the switch points is transmitted further by connecting rods located below the beam, to a torque tube that moves segments of articulated rail for clearing the passage of driving vanes connected to the vehicle through a longitudinal slot in the beam, in the same direction established by the position of the switch points of the line changing equipment. Stop valves for the module are provided in the two bifurcated ends of the duct for interrupting the flow in the portion of the line not selected by the line changing equipment.
