  • Publication number: 20110083420
    Abstract: A ramjet engine (3, 4, 5), flying at Mach 3 has 64% efficiency, and at Mach 4 has 76% efficiency. Ramjet engines are currently only used for supersonic flight and have not been used as stationary engines with mechanical output. The present invention, in addition to subsonic flight, can be operated as a stationary engine, and can expand the use of the ramjet engine for mechanical output in vehicles, power plants, and in generator sets for large buildings, homes, and industry. The present invention provides the means to use ramjet engines as stationary engines by building nearly adiabatic compressors (1, 2, 12, 13, 14, 15) and expanders (6, 7, 8, 9, 10, 11) capable of (de-)compression ratios up to about 92:1 to supply the high energy gas/air required by ramjet engines, and shows how to replace de Laval nozzles with sonic converters (49, 50, 51) that convert supersonic to subsonic flow and sonic convertors (45, 46, 47) that convert subsonic to supersonic flow without having choke areas.

  • Publication number: 20060260183
    Abstract: A membrane enclosed fluid diffusion system for insect attractants and repellents, auto thermostatic heaters, and chemical delivery using an additive and/or selectively permeable membrane that interacts with the enclosed fluid to maintain steady delivery rates over a range of temperature and humidity. Systems can be formed with permeable membranes, impermeable membranes, chemical hydrates, wicks, scent fluids, fuel fluids, catalytic heaters, energy conversion devices, visible images, infrared images, trapping systems, sound systems, electronics, and apparel. The device results in efficient and effective devices for mosquito control drug delivery, and portable heaters.

  • Publication number: 20050186871
    Abstract: Photocatalysts, electrets, and hydrophobic surfaces are geometrically integrated to achieve a self-cleaning air filter, fabric, or surface. This can be incorporated into surfaces and apparel to wick, disinfect, deodorize, and clean their surfaces with the action of the photocatalyst, water, and light on absorbed chemicals, bacteria, funguses, viruses, and particulates. The photocatalysts can be electrically connected to achieve electro-osmotic control and electrical energy output. This leads to protection from chemicals, bacteria, funguses, viruses, and greater humidity control and comfort in apparel, structures, air cleaners, and in particular, eyewear.
