Method of removing mercury from exhaust gases
InactiveUS6962617B2Effectively adsorbing and reacting mercurySimple methodGas treatmentUsing liquid separation agentHydrogenSorbent
Efficient removal of mercury from the exhaust gases of an industrial process or combustion process can be achieved using an adsorbent that can be regenerated by a simple and efficient method. The mercury is contacted with a sorbent material, the sorbent material being hydrogen mordenite or hydrogen clinoptilolite, for adsorbing mercury and causing the mercury to react with the sorbent material to produce mercury-laden sorbent material. The mercury-laden sorbent material can be heated to a temperature of at least about 400° C. so as to remove mercury from the mercury-laden sorbent material and to regenerate the sorbent material to allow reusing of the sorbent material for mercury removal.

Violation of time reversal invariance in living tissue
InactiveUS6592611B1Eliminate needSynergistic effectivenessSurgical instrument detailsLight therapyDiseaseWavenumber
The present invention provides for a device, a method, and a treatment system for chronic disease conditions. The present invention was designed using the theoretical concepts of Quantum Biology. The principles of operation are based on the device's ability to stimulate a Bose-Einstein condensate and excitation of Frolich resonance in living tissue The wavenumbers necessary for this excitation are derived from the solution to the equations for optical phonon scattering in living tissue generated by optical photon excitation. The establishment of this degeneracy condition induces a super conducting state in the tissue. This super conducting state facilitates DNA replication, transcription and translation, thereby allowing the proper formation or regeneration of healthy tissue. This superconducting state provides the conditions necessary for establishing the violation of time reversal invariance in living tissue.

Exhaust gas cleaning device for internal combustion engine
ActiveUS20050252198A1Efficient regenerationReduce fuel consumptionElectrical controlInternal combustion piston enginesParticulatesTop dead center
In an engine, when it is determined that catalyst, which is held on a filter substrate of a particulate filter, is not in an active state, an ECU executes a fuel injection for mainly obtaining an engine power near a top dead center of a crank. Then, the ECU executes a subsequent fuel injection after lapse of a sufficient injection interval, which does not cause misfiring, to increase the temperature of exhaust gas outputted from the engine. In this way, the temperature of the filter is rapidly increased.

Process and system for operating magnetron discharges
InactiveUS6340416B1Improve efficiencyReduce output lossCellsElectric discharge tubesLoad carryingSupply energy
Magnetron discharges are pulse-operated to avoid the so-called "arcing". In the case of magnetron discharges from alternating current-fed magnetrons, the process is limited to the minor power of the energy supply because of the load-carrying capacity of the required electric components. When the magnetron discharges are fed by direct current, their effectiveness deteriorates because of the deposition of layers on the anode surfaces. The new process should enable a high supply power and prevent arcing. In magnetron discharges with at least two magnetron electrodes, the energy is supplied in such a way that at least one magnetron electrode is a cathode or anode and a number n1 of direct current pulses of said polarity is supplied. The poles of at least one magnetron electrode are then reversed and a number n2 of direct currents of this polarity are supplied. The process is carried on in this manner, the frequency of the direct current pulses being higher than that of the polarity reversals. The energy supply effectiveness is thus improved. This process and system enable the production of layers having the most different properties, for example for the glass, packaging, electronic, and machine construction industries.

In a method and apparatus for regenerating a lean NOx adsorber, the NOx adsorber treats exhaust gases created during the combustion of gaseous fuels in general. A bypass line maintains a target regeneration flow of exhaust gas through the NOx adsorber during regeneration regardless of operating demands on the engine. Closed-loop and open-loop control are employed. The closed-loop control employs sensors that determine properties of the exhaust gas during regeneration, and the controller uses those properties to provide an efficient regeneration cycle. A regeneration map is also provided that uses creation of in-cylinder regeneration conditions for the exhaust gas in combination with in-line regeneration conditions for the exhaust gas.

A method and apparatus for converting thermal energy to mechanical energy which can use a wide range of fuels and perform with a high efficiency. Operating on a little utilized thermodynamic cycle of isentropic compression, isothermal expansion, isentropic expansion and finally constant pressure cooling and contraction. The external heat engine utilizes a heat exchanger carrying heat from the external energy source to the working parts of the engine. Pistons and cylinders are activated by appropriate means to adiabatically compress the working fluid, for example ambient air, to transfer the entire mass of the air through the heat exchanger to accomplish isothermal expansion followed by adiabatic expansion and, finally, exhaust the air to ambient to allow for constant pressure cooling and contraction. Valve pistons in conjunction with the cylinders form valves that allow for the exchange of working fluid with ambient. Energy is added to the engine during isothermal expansion, whereby the energy of compression is added by a flywheel or other appropriate energy storage means, said flywheel stores energy recovered during adiabatic expansion. The thermodynamic cycle described and the engine embodiments disclosed, when run in reverse, perform as a heat pump or refrigeration device.

An exhaust gas cleaning system of a diesel engine includes a diesel particulate filter (a DPF) disposed in an exhaust passage, and a diesel oxidation catalyst (a DOC) disposed upstream of the DPF. When an electronic control unit (an ECU) performs a temperature increasing operation such as post-injection to eliminate particulate matters accumulated in the DPF, a ratio (a duty ratio) between a performing period and an interrupting period of the temperature increasing operation is changed in accordance with temperature of the DPF. Thus, a quantity of hydrocarbon supplied to the DOC is controlled stepwise or continuously. Thus, the temperature of the DPF can be increased to target temperature quickly and can be maintained near the target temperature when the regeneration of the DPF is performed.
