Abstract: A solar furnace receiving reflected solar energy from a battery of remote, positionable mirrors with the furnace having primary and secondary reflectors directing concentrated radiant energy toward a Fresnel lens. The focal point of the lens is located within a furnace chamber into which is advanced a carbon conduit, the advancing end of which is vaporized by focal point temperatures. The vaporized carbon serves as a catalyst for the production of hydrogen. The furnace chamber is in upstream communication with means for separating hydrogen and carbon dioxide.

Abstract: A purification system for producing extremely pure H.sub.2 from H.sub.2 gas streams containing water and small amounts of O.sub.2 comprises a single column with alternating layers of adsorbent and a catalyst for the reaction 2H.sub.2 + O.sub.2 .fwdarw. 2H.sub.2 O. The alternating layers are arranged so that the gas to be purified first meets an adsorbent layer, next a catalyst layer and finally an adsorbent layer. Two such columns can be operated alternatively, one being used to produce purified gas, while the other is backflushed with as little as 2% of the product gas of the operating column. By this technique, H.sub.2 gas can be produced having a purity as high as 99.9999% or higher. The inventive system can also be used to purify O.sub.2 gas streams containing water and small amounts of hydrogen.

Abstract: The invention relates to the gettering of hydrogen and its isotopes, the gettering materials being painted or coated onto, or otherwise disposed in an area or volume from which hydrogen is to be removed.

Abstract: Cyanogen chloride is purified and the service life of activated carbon is increased in the subsequent trimerization of the cyanogen chloride to cyanuric chloride by process comprising reacting hydrogen cyanide with chlorine, in a given case in the presence of cyanogen chloride produced in the presence of water, which in a given case contains chlorine. The improvement comprises passing the cyanogen chloride over granular commercial sodium aluminum silicate or a molecular sieve of the mordenite type, at 20.degree.-100.degree.C., preferably 30.degree.-60.degree.C.

Abstract: A recycle loop method and recuperative heating system is provided for thermally recombining hydrogen and oxygen, such as may be desired in connection with a dissociated gas stream from a containment vessel for a nuclear reactor under loss of coolant accident conditions. The dissociated charge stream is preferably heated by indirect heat exchange with a resulting water vapor containing combined stream to effect heat conservation and, also preferably, the recuperative heat exchange operation and the high temperature recombining reaction are carried out in a unitary zone incorporating electrical, non-flame, heat input means.

Abstract: A system for reducing radioactivity released to the biosphere in the course of producing natural gas from a reservoir stimulated by the detonation of nuclear explosives therein. Tritiated water produced with the gas is separated out and returned to a nuclear chimney through a string of tubing positioned within the well casing. The tubing string is positioned within the well casing in a manner which enhances separation of the water out of the gas and minimizes entrainment of water into the gas flowing out of the chimney.
