Abstract: Calcium formate is heated to a temperature in the range of from 300.degree. to 400.degree. C to form calcium carbonate, hydrogen and carbon monoxide and the gases are bled off. The calcium carbonate is then heated to about 825.degree. C whereby calcium oxide and carbon dioxide are formed and the gas is again bled off. The calcium oxide is then reacted with water to form calcium hydroxide and the calcium hydroxide is reacted with carbon monoxide to regenerate calcium formate and start the process over again. The process provides a convenient method for obtaining a mixture of hydrogen and carbon monoxide gases which are useful for many purposes. The carbon monoxide may be removed from the mixture of gases produced to obtain hydrogen which also finds many uses. Further, a mixture of hydrogen and carbon monoxide suitable for use in the Fischer-Tropsch reaction may be readily produced.

Abstract: A fluid polymeric ablator liner is cast onto the inner surface of a ramjet ombustion chamber which has been prepared with a screen liner substrate. A split mold is inserted through the nozzle and assembled inside the chamber allowing a thin layer of ablator to be cast and cured on the dome and nozzle regions of the combustion chamber.

Abstract: The warhead of a missile is loaded with a payload that can either be burned r exploded. If propulsion is lost and either aerodynamic steering is not present or the velocity level of the missile is degraded to a point where steering is marginal, steerage is maintained by igniting the warhead payload and exhausting gases through nozzles attached to the warhead.

Abstract: A device comprising an outer shell, open at one end, a charge carrier for carrying shaped charges suspended within the outer shell and means for releasing gas suspended within the outer shell used in the stimulation of geothermal wells.

Abstract: Methods for the dispersal of both warm and cold fogs with 1,1,1-tris-(hydymethyl)ethane. Warm fogs are dispersed by spraying hot aqueous solutions of the material into the fogged area. Cold fogs are dispersed by generating smokes containing submicron particles of the material and dispersing the smokes within the fogged area.

Abstract: A barrier layer made up of a suitable powder interspersed within either a trix of cured propellant binder or a matrix of silicone rubber is interposed between a silicone rubber insulator and a solid propellant grain in a rocket motor to prevent curatives from migrating from the propellant into the silicone rubber layer when the propellant is cast.

Abstract: 1,1,4,4-Tetrakis(trifluoromethyl)butan-1,4-diol and 1,1-bis (trifluoromethyl)propanol-1 are prepared by reacting gaseous hexafluoroacetone and ethane in a transparent container in the presence of sunlight. The diol is a crystalline solid and the propanol-1 is a liquid. The diol is useful as a monomer in the field of polymer chemistry. That is, polymers such as polyurethans and polyesters which find many applications in the chemical industry can be made by reacting the proper material with the diol of this invention. The propanol-1 is useful as a plasticizer for polyurethans and other plastics.

Abstract: Nitric acid and n-octane are injected into a gun and utilized to propel pectiles.
