  • Publication number: 20080000215
    Abstract: The present invention relates generally or preferably to pulsed hypersonic compression waves and more particularly to shaped charge devices using pulsed hypersonic compression waves to create thrust, two-cycle internal and external combustion engines, rotary machines and more specifically to internal and external rotary combustion engines, fluid compressors, vacuum pumps, and drive turbines for expandable gases or pressurized fluid and water, as well as hydrogen. Other systems include machines and procedures employed during in-process drying of moisture-laden materials employing a reaction chamber forming a pressurized and heated gas.

  • Publication number: 20050284440
    Abstract: A rotary machine having a housing with rotary components disclosed within. The rotary machine is configurable as an internal combustion rotary engine, an external combustion rotary engine, a gas compressor, a vacuum pump, a liquid pump, a drive turbine, or a drive turbine for expandable gases or pressurized liquids. The combustion engine employs a new thermal cycle—eliminating the Otto cycle's internal compression of the combustion products as part of the cycle. The new combustion thermal cycle is intake, expansion and exhaust.
