摘要: Articles and methods for installing hook bolts on bridge decks constructed of timbers and structural steel members. A tether is lowered through a hole in a timber, captured below the bridge deck, and drawn upward around the timber or between timbers. A hook bolt is engaged with the end of the tether that was lowered through the hole and drawn upward, then lowered under the bridge deck and drawn upward through the hole in the timber. The hook bolt engages with a flange on a structural member of the bridge deck.

摘要: Methods, systems, and apparatus, including an apparatus that is a rail anchor comprising a head, a tail, and a belly section. The belly section comprises a top surface, a bottom surface, and two side surfaces. Each side surface comprises a contact-bearing surface area. The head comprises a bend along a length of the head. The tail comprises a notch. Each contact-bearing surface area has a surface area of at least 3 square inches and is adapted to extend at least 1.5 inches downward from the top of a railroad track crosstie along a side of the railroad track crosstie.

摘要: An AC motor is utilized to drive a closure on a vehicle. The use of the AC motor provides valuable benefits with regard to cost and size. Further, a three-phase AC motor may be utilized, and the pulses in its power supply monitored to determine an obstruction in the path of the closure. Frequency control may also be utilized to provide optimum control of the drive of the component at both start-up and stop.

摘要: An apparatus for controlling multiple vehicle systems includes a single power supply that provides a direct current source. The power supply is comprised of a thirty-six volt (36 V) battery power distribution system. A converter is electrically connected to the power supply to convert direct current to alternating current. A plurality of induction motors are used to operate various vehicle systems. The motors receive alternating current via electrical connections between the converter and the motors. A central processor is connected to relays sending power to each of the motors and provides control signals to the motors based on input from control members used to activate each of the various vehicle systems. At least one sensor is associated with each of the motors to monitor voltage or current of the respective motor and to generate a diagnostic signal that is sent to the processor. The processor generates a warning signal when any of the diagnostic signals indicates that voltage within the respective motor is outside a predetermined range. A piezoelectric material is associated with each of the motors to provide an internal control signal for the motor. The piezoelectric material can be used to control acceleration or deceleration of the motor based on the rotational force of a rotor within the motor or can be use to activate an auxiliary winding in the motor based on mechanical input to the respective controller.

摘要: A plurality of motors for use in driving accessories on a vehicle, are each powered by three-phase current. A single controller controls the supply three-phase current to the plurality of motors. In another aspect of the invention, pseudothree-phase current is created from a direct current voltage source. A chopping circuit chops the voltage into a plurality of pulses, and a phase shift circuit then creates phase-shifted power signals from those pulses. The present invention thus enables the use of three-phase alternating current motors on a vehicle to drive accessories. This reduces the cost and size of the required motors.

摘要: An improved fastener for attaching metal to wood is provided. The fastener is particularly suited for use as a railroad spike for attaching a metal rail to a wooden tie. The improved spike is adapted for installation by either driving or screwing the spike into the tie. A plurality of flutes are adapted to engage with the tie, thereby preventing loosening of the spike. The spike may be used with or without a metal boss or fishplate to secure a metal rail to a wooden tie.

摘要: A piercing grommet which pierces an insulation blanket. A snap-on retainer slides over a spiked portion of the piercing grommet and snaps in place adjacent the bottom of the spike. The spike can then be removed. A seal is created by contact adhesive between the insulation blanket and the grommet in order to prevent moisture ingress.
