Abstract
Abstract A system for the irradiation of a target with electromagnetic energies covering the region between approximately the infra-Xray and the trans-infrared portions of the spectrum comprises: light associated with a shock wave front aligned to strike a tape valve comprising a movable tape, impervious to said shock wave, having a mirror-like surface and also at least one aperture in spaced relation to said surface and means for moving said tape at a speed such that said light strikes the mirror-like surface and said shock wave front passes through said aperture; a shock sensitive irradiable target optically coupled to said mirror-like surface and said movable member, whereby to provide via said movable member a light-coupling between said target and light source.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
250 words
An apparatus comprising an irradiable target and means for the irradiation of said target with electromagnetic energies covering the region between approximately the infra-X-ray and the trans-infrared portions of the spectrum, said means comprising: means for generating light and an associated shock wave front and a gas flow passage which is aligned so that said light and a shock wave front can strike said tape valve, said tape valve comprising a movable tape member having a mirror-like surface and also at least one aperture in said tape and means for moving said member at a speed such that said light strikes the mirror-like surface and said shock wave front passes through said aperture; and wherein said irradiable target is optically coupled to said mirror-like surface and said movable member to provide via said movable member a light-coupling between said target and light source, and wherein said movable member is impervious to said shock wave and wherein said moving means comprises means for driving said tape at a high velocity between two aligned portions of said passage and for moving said tape transversely with respect to the length of said passage, said aperture which when moved into registry with said two aligned portions comprises the opening of said valve permitting communication between said aligned passage portions, and means for maintaining said tape centered in the gap between said aligned portions, as the tape moves, said means providing application of oppositely directed gas flows to the respective opposite faces of the tape.
Claim 2
Independent Claim
250 words
An apparatus comprising an irradiable target and means for the irradiation of said target with electromagnetic energies covering the region between approximately the infra-X-ray and the trans-infrared portions of the spectrum, said means comprising: means for generating light and an associated shock wave front and a gas flow passage which is aligned so that said light and a shock wave front can strike said tape valve, said tape valve comprising a movable tape member having a mirror-like surface and also at least one aperture in said tape and means for moving said member at a speed such that said light strikes the mirror-like surface and said shock wave front passes through said aperture; and wherein said irradiable target is optically coupled to said mirror-like surface and said movable member to provide via said movable member a light-coupling between said target and light source, and wherein said movable member is impervious to said shock wave and wherein said moving means comprises means for driving said tape at a high velocity between two aligned portions of said passage and for moving said tape transversely with respect to the length of said passage, said aperture which when moved into registry with said two aligned portions comprises the opening of said valve permitting communication between said aligned passage portions, and means for maintaining said tape centered in the gap between said aligned portions, as the tape moves, said means providing application of oppositely directed gas flows to the respective opposite faces of the tape.
Claim 3
Dependent Claim
50 words
The combination of claim 1 wherein said system includes critical flow orifices and wherein said oppositely directed gas flows are produced within said critical flow orifices thereby permitting equilization of the pressure on each side of said movable member and preventing contact of said movable member with said aligned portions.
Claim 4
Dependent Claim
20 words
The combination of claim 1 wherein said light and said shock wave front are produced within an internal combustion engine.
Claim 5
Dependent Claim
20 words
The combination of claim 1 wherein means are included for introducing xenon into the region behind the reflected shock wave.
Claim 6
Dependent Claim
17 words
The combination of claim 1 wherein means are included for maintaining carbon dioxide in the laser cavity.
Claim 7
Dependent Claim
18 words
The combination of claim 1 wherein said light and shock wave front are produced within a wave rEactor.
Claim 8
Dependent Claim
22 words
The combination of claim 6 wherein means are included for producing said shock wave front utilizing a gaseous hydrocarbon under high pressure.
Claim 9
Dependent Claim
29 words
The combination of claim 7 wherein means are included for causing said shock wave front to initiate a chemical reaction involving said hydrocarbon and at least one additional reagent.
