摘要： A compact diffuser for recovering pressure from a supersonic flow with boundary layers. Sharp splicer plates near the wails form boundary layer scoops and separate the flow into an inner coreflow chapel and outer chambers containing small supersonic ejector nobles. The coreflow without boundary layers undergoes a single near-normal shock to recover pressure. The boundary layers are pumped to the recovery pressure in the outer ejector chambers. The subsonic part of the boundary layer flow to the outer chambers can be choked against boundary layer scoop inlet corners to isolate the upstream flow. The leading edge angle of the splicers may be selected to help induce coreflow shocking.

摘要： A gas lens 10 for lensing a light beam 12. A first gas is injected through orifices 18-18.sup.n into enclosure 16 thereby forming a row of jets 14-14.sup.n. A second gas having a different index of refractivity than the first gas also is contained within the enclosure 16 in the form of a mantle 24 surrounding each jet 14-14.sup.n. The light beam 12 is lensed (either convergently or divergently) as it passes through the jet/mantle interfaces.

摘要： Material such as an oil slick floating on a body of liquid, ordinarily water, is collected by a mechanism comprising an impeller beneath the liquid surface and a rotatable tubular element which together form a free vortex as the surface of the body of liquid that draws the material into a vortex pocket from which it can be pumped.
