摘要： A heating system for a subsurface formation is described. The heating system includes a first heater, a second heater, and a third heater placed in an opening in the subsurface formation. Each heater includes: an electrical conductor; an insulation layer at least partially surrounding the electrical conductor; and an electrically conductive sheath at least partially surrounding the insulation layer. The electrical conductor is electrically coupled to the sheath at a lower end portion of the heater. The lower end portion is the portion of the heater distal from a surface of the opening. The first heater, the second heater, and the third heater are electrically coupled at the lower end portions of the heaters. The first heater, the second heater, and the third heater are configured to be electrically coupled in a three-phase wye configuration.

摘要： A method and system for determining a ground speed for locomotives (e.g., 12, 14) of a train (16) comprising at least two locomotives for use in controlling an operation of the train. The method includes selecting an axle of any one locomotive of the train for measuring a speed corresponding to the selected axle. The method also includes determining a ground speed for at least another locomotive of the train based on a measured speed corresponding to the selected axle of the one locomotive.

摘要： In order to provide a transport system with a conductor system, which includes at least one supply conductor, which is connected to an energy source, at least one transport carriage movable along a travel path relative to the conductor system and at least one device for the non-contact transmission of energy from the conductor system to the transport carriage, in which transport system the stationary conductor loop has an inductance that is as low as possible and in which ohmic losses are kept as low as possible, it is proposed that the transport system includes at least one induction conductor, which at least in sections is arranged so closely adjacent to the supply conductor that an electric current flowing in the supply conductor generates an induction current in the induction conductor, wherein the induction conductor has at least two end regions, which are short-circuited to one another, and/or wherein the induction conductor is closed in a ring shape.

摘要： A hybrid propulsion system. The system comprises one or more hybrid propulsion traction drives having an electric motor operable to produce mechanical power for propulsion. A hybrid propulsion traction drive is operable to receive power from an on-board power generation system. The electric motor is operable to receive power from an energy storage unit and operable to supply power to the energy storage unit. The energy storage unit may be coupled to the electric motor via a switch.

摘要： A monorail system for passenger and light freight transportation provides a support structure with an essentially planar top surface and a stabilizer guide rail having a vertical web portion supporting a head portion. The head guides a vehicle along the top surface while conductors secured to the web portion transmit electrical current to the vehicle through a current collector secured to the vehicle. A portion of the stabilizer guide rail may be flexible providing a simple, inexpensive device for switching the vehicle between a plurality of tracks. The system operates equally well with a variety of vehicle propulsion and suspension systems including electromechanical, magnetic levitation or linear electric motors. In addition, the system may be operated with a semi-maglev system, wherein the vehicle is partially supported by wheels and magnetic levitation.

摘要： An apparatus (10) for transporting a load, in particular for transporting a container, particularly of the gantry type, includes an electrical power user element (30a, 30b, 30c, 30d, 32a) which has a respective control element (30'a, 30'b, 30'c, 30'd, 32'a), and an element (34, 36) for supplying electrical power to the user element (30a, 30b, 30c, 30d, 32a). The element for supplying electrical power includes at least an internal combustion engine (34) and an element (36) for transforming the mechanical power generated by the internal combustion engine into electrical power to be supplied to the user element. Advantageously, there are elements which allow a change in the operating speed of the internal combustion engine (34) according to the power required by the user element.

摘要： A control system and method which includes storing the geographic location of the neutral sections along the path onboard the vehicle. A GPS system on the vehicle determines the geographic location of the vehicle. A program of the control system determines the position of the vehicle relative to the position of the neutral section from memory using the GPS to determine the location of the vehicle. Next, it provides a control for maintaining the circuit breaker of the vehicle open as the source collector passes through the neutral section.
