Patent number: 8561545Abstract: A method is disclosed for constructing a locomotive, in part, from serviceable used parts from one or more other locomotives. The principal part that is used in this new locomotive configuration is a single, used locomotive truck assembly. The various embodiments and configurations of the present invention are directed generally to a purpose-built locomotive that incorporates parts from other locomotives in a unique way. The present invention can be summarized as a method creating a simple locomotive that is well adapted to switching and spotting functions that shares commonality with other larger locomotives both in terms of components and design. Because this new piece equipment is built in part from a plentiful supply of under-valued surplus components, it will be economical to construct and maintain. The locomotive may also include a self-elevating system so that the truck assembly can be accessed or removed rapidly for maintenance or repairs.Type: GrantFiled: January 28, 2011Date of Patent: October 22, 2013Inventor: Frank Wegner Donnelly

Patent number: 8244419Abstract: A marine power system comprises a motor for providing propulsion. It also comprises an energy storage unit (ESU) for storing and supplying energy to the motor. A prime power system is connected to the ESU and motor for selectively providing energy to these subsystems through a bus. The motor selectively receives energy from the prime power system and the ESU and can supply regenerative braking energy to the bus. The system can also accommodate multiple generator sets providing system power. The ESU can also provide starting power for the prime power system. Alternately, the prime power system drives a mechanical power system output shaft connected to the motor, and the marine system comprises an alternator driven by the prime power system output shaft. The ESU can transmit energy to the alternator. The prime power system can be located on a tugboat displacing a barge carrying the energy storage unit.Type: GrantFiled: October 24, 2007Date of Patent: August 14, 2012Assignee: Mi-Jack Canada, Inc.Inventors: Frank Wegner-Donnelly, John David Watson

Publication number: 20120201657Abstract: The present disclosure discloses an engine braking system, especially for vehicles powered by a gas turbine. The engine braking system allows for control of engine braking force; control of over-speed of the power turbine and further includes means of recovering some or all of the braking energy of the engine braking system. Dissipative engine braking devices include an auxiliary compressor, or electrical generator, or an eddy current clutch or an eddy current brake, or fluid pump. Several methods of controlling the engine braking force of a dissipative braking device are disclosed and include (1) a continuously variable transmission (“CVT”); (2) an electrical generator and an optional thermal storage device; (3) an eddy current clutch; and (4) a fluid pump system. The various control devices may be operated automatically by appropriate algorithms. One of these control methods utilizes an eddy current clutch assembly.Type: ApplicationFiled: August 15, 2011Publication date: August 9, 2012Applicant: ICR TURBINE ENGINE CORPORATIONInventors: Frank Wegner Donnelly, David William Dewis

Patent number: 8220572Abstract: Various control options are applied for selecting the number of operating power sources for a multi-power source vehicle having a number of prime power sources and, optionally including energy storage systems. This system and method are applicable to large vehicles such as locomotives, mining trucks, tugboats and large cranes. Selectable operating modes are provided for different locomotive speed ranges and work loads. The system and method are based on a common DC bus electrical architecture so that prime power sources need not be synchronized. Multiple-engine locomotives are included in which the engine systems may be electrically connected in parallel or in series or in combinations of parallel and series to a DC bus.Type: GrantFiled: June 15, 2007Date of Patent: July 17, 2012Assignee: Railpower, LLCInventor: Frank Wegner Donnelly

Publication number: 20120175886Abstract: A system of dense packaging of turbomachinery in a gas turbine engine by means of close-coupling of components and by the ability to rotate various engine components with respect to other engine components is disclosed. In addition, spool shaft rotational direction may be reversed to suit the application. In multiple engine configurations, the same ability to close-couple and rotate components and to reverse shaft rotational direction in order to rearrange the engine geometry package is used for packaging two or more gas turbine engines to achieve high power density. Dense-packing is possible because of a number of features of the basic engine.Type: ApplicationFiled: September 6, 2011Publication date: July 12, 2012Applicant: ICR TURBINE ENGINE CORPORATIONInventors: Frank Wegner Donnelly, David William Dewis

Publication number: 20120042656Abstract: A closed-loop organic Rankine cycle apparatus to extract waste heat from the exhaust gas from a gas turbine engine is disclosed wherein the closed loop includes at least one additional heat exchanger. An additional heat exchanger for heating fuel may be in one of three locations relative to the ORC turbine and condensing heat exchanger. One location is a preferred location for adding heat to all fuels (liquid, gaseous and/or cryogenic). Another location is a practical location for adding heat to very cold or cryogenic fuels such as CNG or LNG. The closed-loop organic Rankine cycle apparatus, besides extracting waste heat from the exhaust gases, may also include an additional heat exchanger to recover heat from a compressor on a gas turbine engine prior to entering an intercooler on a gas turbine engine. In another embodiment, the exhaust stream can be directed, in selected proportions, to a closed organic Rankine cycle, a heat exchanger for pre-heating fuel or directly out an exhaust stack.Type: ApplicationFiled: August 22, 2011Publication date: February 23, 2012Applicant: ICR TURBINE ENGINE CORPORATIONInventors: Frank Wegner Donnelly, David William Dewis, John D.

Publication number: 20110288738Abstract: The present invention discloses a method and enabling apparatus for integrating a new fuel or fuels into an operating transportation system in a continuous, seamless manner. The method disclosed overcomes the economic risk associated with developing a new fuel when there is little or no fuel distribution infrastructure in place for the new fuel. Integrating a new fuel into an existing transportation system can be implemented with two enabling technologies. The first is an engine capable of operating seamlessly on multiple fuels. The second is a system of determining a driving strategy that makes the transition from one fuel to another seamless to the driver. A compact, high-performance gas turbine engine is an enabling apparatus of the above strategy. The system of driving strategy disclosed herein allows the operator of the vehicle or the fleet manager to minimize operational costs by estimating the best combination of fuels, fuel dispensers and driving strategies.Type: ApplicationFiled: April 19, 2011Publication date: November 24, 2011Applicant: ICR TURBINE ENGINE CORPORATIONInventors: Frank Wegner Donnelly, David William Dewis, Douglas W.

Publication number: 20110215640Abstract: The placement of fully available prime movers having a DC output at a location inside or adjacent to an inverter-based intermittently available renewable energy site is disclosed. The fully available prime movers add reliability to an unreliable energy asset that is reaching its maximum penetration within the grid due to its unpredictability and the requirement for additional spinning reserves in other parts of the grid. The present invention can provide a portion or all of the power to an intermittently available renewable power generating facility so that the power output to the power grid is dispatchable power. In particular, a method and means are disclosed to utilize high-efficiency engines operated on various fuels some of which may be non-fossil fuels to maintain a constant power output from an otherwise intermittent power generating facility.Type: ApplicationFiled: March 2, 2011Publication date: September 8, 2011Applicant: ICR TURBINE ENGINE CORPORATIONInventors: Frank Wegner Donnelly, David William Dewis
