  • Patent number: 7629699
    Abstract: This invention overcomes the disadvantages of the prior art by providing a power generating system particularly suitable for field use in remote locations, which is fuel-efficient, relatively quiet, tolerant of dust, capable of operating on low-grade logistics and diesel-like fuels and capable of generating between 500 W and 2 KW of continuous electrical power. This generating system employs a two-cycle MICE generator having a piston that operates within a cylinder, and an interconnected, axially moving piston shaft that oscillates an alternator coil within a magnetic core. The piston shaft is attached to, and resisted by, the free end of a strong spring with a second, opposing end fixed to the MICE casing. To control operation of the MICE generator a clipper circuit is employed with a set threshold to resolve peaks and an adjustable harshness for applying load to the coil based upon an amps/volt harshness setting.

  • Publication number: 20050260468
    Abstract: A self-contained power generator comprises a fuel source, a solid oxygen source capable of releasing oxygen when heated, an engine capable of generating power by combusting the fuel with the oxygen so as to produce exhaust gases, and an exhaust gas absorbent. The oxygen source and the exhaust gas absorbent are preferably combined. The oxygen source may comprise potassium superoxide in combination with sodium peroxide, potassium oxide, or calcium oxide The engine may be any known heat engine. Fuel is fed to the engine at a desired rate so as to generate power at a desired rate. Heat from said combustion is preferably applied to the oxygen source and heat may be exchanged between the exhaust gases and oxygen. The exhaust gases are preferably absorbed at substantially the same rate as the rate at which they are generated such that pressure in the generator does not increase.

  • Patent number: 5672190
    Abstract: Process and furnace for the continuous production of a molten pool from particulate meltable batch materials such as glass-forming raw materials. The raw materials, in particulate form, are injected into and suspended in combustion gases within a combustor section to form a particle-laden gas flow. The gas flow is accelerated vertically downwardly into a refractory chamber to impact the surface of a molten pool, producing inertial separation of the molten particles into the pool and strong shear forces by the exiting combustion gases, resulting in pool circulation and improved fining and homogeneity.
