  • Engine reformer systems for lower cost, smaller scale manufacturing of liquid fuels
    Patent number: 9909491
    Abstract: A reformer-liquid fuel manufacturing system that utilizes an engine to generate hydrogen-rich gas is disclosed. The engine operates at very rich conditions, such as 2.5<?<4.0. In doing so, it creates an exothermic reaction, which results in the production of syngas. In addition, the system utilizes the energy from the exothermic reaction to rotate a shaft and also utilizes the heat in the syngas to heat the reactants. A mechanical power plant is in communication with the rotating shaft and can be used to produce oxygen, provide electricity or operate a compressor, as require. The hydrogen-rich gas is supplied to a chemical reactor, which converts the gas into a liquid fuel, such as methanol.

  • Method and system for removing retentate from filters
    Patent number: 9873074
    Abstract: A cleaning system and method of cleaning filters that removes the ash in the plugged regions is disclosed. The filter is subjected to vibrations, which serve to loosen trapped and packed retentate from the filter. The loosened retentate is then captured by a collection bin. The cleaning system can be integral with the intended application, such as within an automobile. In another embodiment, the cleaning system is a separate cleaning station, where the filter is removing from its intended application, cleaned, and then reinstalled.

  • FUEL MANAGEMENT SYSTEM FOR VARIABLE ETHANOL OCTANE ENHANCEMENT OF GASOLINE ENGINES
    Publication number: 20180016998
    Abstract: Fuel management system for efficient operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder of the engine. A fuel management microprocessor system controls injection of the anti-knock agent so as to control knock and minimize that amount of the anti-knock agent that is used in a drive cycle. It is preferred that the anti-knock agent is ethanol. The use of ethanol can be further minimized by injection in a non-uniform manner within a cylinder. The ethanol injection suppresses knock so that higher compression ratio and/or engine downsizing from increased turbocharging or supercharging can be used to increase the efficiency or the engine.

  • Toroidal bending magnets for hadron therapy gantries
    Patent number: 9711254
    Abstract: Toroidal superconducting magnets can be used as lightweight rotating bending magnets in hadron therapy gantries. The toroidal bending magnets are self-shielded and do not require ferromagnetic material for field modification or shielding, decreasing both the magnet system weight, as well as overall gantry weight. Achromatic magnet can be made by combining two of these bending magnets. The simple geometry may allow the use of higher fields, making it attractive for carbon, as well as proton.

  • Phase-lock loop synchronization between beam orbit and RF drive in synchrocyclotrons
    Patent number: 9615441
    Abstract: The invention specifies the use of feedback in the radio frequency (RF) drive for a synchrocyclotron, controlling the phase and/or amplitude of the accelerating field as a means to assure optimal acceleration of the beam, to increase the average beam current and to alter the beam orbit in order to allow appropriate extraction as the beam energy is varied. The effect of space charge is reduced by rapid acceleration and extraction of the beam, and the repetition rate of the pulses can be increased. Several means are presented to monitor the phase of the beam in synchrocyclotrons and to adjust the phase and amplitude of the RF to optimize the acceleration of the beam and to adjust the extraction and injection of the beam. Also, the use of a pulsed ion source that matches the acceptance window of the synchrocyclotron is described.

  • REGENERATOR FOR SYNGAS CLEANUP AND ENERGY RECOVERY IN GASIFIER SYSTEMS
    Publication number: 20170009162
    Abstract: A rotating heat regenerator is used to recover heat from the syngas at it exits the reactor vessel of a waste or biomass gasifier. In some embodiments, three or more streams are passed through the heat exchanger. One stream is the dirty syngas, which heats the rotating material. A second stream is a cold stream that is heated as it passes through the material. A third stream is a cleaning stream, which serves to remove particulates that are collected on the rotating material as the dirty syngas passes through it. This apparatus can also be used as an auto-heat exchanger, or it can exchange heat between separate flows in the gasifier process.

  • Port Injection System For Reduction Of Particulates From Turbocharged Direct Injection Gasoline Engines
    Publication number: 20160326971
    Abstract: The present invention describes a fuel-management system for minimizing particulate emissions in turbocharged direct injection gasoline engines. The system optimizes the use of port fuel injection (PFI) in combination with direct injection (DI), particularly in cold start and other transient conditions. In the present invention, the use of these control systems together with other control systems for increasing the effectiveness of port fuel injector use and for reducing particulate emissions from turbocharged direct injection engines is described. Particular attention is given to reducing particulate emissions that occur during cold start and transient conditions since a substantial fraction of the particulate emissions during a drive cycle occur at these times. Further optimization of the fuel management system for these conditions is important for reducing drive cycle emissions.
