Abstract: A sorbent composition for reducing the stress buildup within sorbent alloys such as hydride powders being used to store hydrogen gas by imparting more of a fluid-like property to the alloys. Under the teachings of the present invention, a second powder is added to the powdered sorbent alloy to serve as a flow aid to the alloy powders so as to allow rearrangement and movement for the alloy powders with respect to each other and with respect to the sidewalls of the container. The flow aid powder which is chemically inert with respect to hydrogen and the sorbent alloys is mixed with the sorbent alloy powder and the amount of the flow aid powder is dependent upon the volume change of the particular hydride, the strength of the container, the geometry of the container, the orientation of the container, and the direction of the reaction front. The addition of the flow aid reduces densification, compaction, settling, and stress buildup during successive cycles of absorption and desorption.

Abstract: In processes utilizing a source of laser energy for achieving a thermonuclear fusion reaction, it is necessary to have fusion fuel prepared in a configuration with minute dimensions and the present invention contemplates preparing this fuel by introducing into hollow microspheres (typically comprised of glass) of predetermined size, in the range of 250 to 2,000 micrometers, a gaseous thermonuclear fuel. One way of accomplishing this is to cause diffusion of gaseous thermonuclear fuel through the walls of the microsphere under conditions of suitable temperature and pressure so that it may be achieved in a reasonable time, after which the fuel can be frozen out on the walls of the microsphere to provide a fusion fuel in a hollow spherical shape. Suitable coatings of additional materials may be applied to the fueled microsphere by appropriate coating methods to complete complex thermonuclear fuel pellet configurations.

Abstract: A material for reversibly storing hydrogen is formed from a lightweight matrix which is chemically and structurally modified to improve its hydrogen storage properties. The utilization of a material which can be any of a number of different disordered structures makes possible the modification of local order chemical environments of the material to increase hydrogen storage capacity and/or improve absorption and desorption properties. Lightweight modifier elements structurally modify the local chemical environments of the matrix to provide a material having an increased density of storage sites to increase hydrogen storage capacity. Transition and rare earth modifier elements structurally modify the local chemical environments to provide a material with an increased density of catalytically active sites for dissociating hydrogen molecules to increase the rate at which hydrogen absorption and desorption can be accomplished.

Abstract: A container made of synthetic material and comprising two compartments, one containing the liquid or other matter the container is to carry, and one, of smaller volume, containing a gas under pressure. The smaller pressurized container rigidifies the structure and may be shaped in such a way as to form a handle or grip for the container. A process and apparatus for manufacturing and filling rows of such containers is also disclosed, said process involving forming a strip of synthetic material into the shape of a letter W in transverse section and performing various welding operations on the strip to form individual containers and to divide off the two compartments.

Abstract: Shaped and fired, porous or impermeable nonvitreous ceramic microcapsules of metal oxide, preferably transparent and polycrystalline, are made by a non-melt process comprising the liquid-liquid extraction of aqueous metal oxide precursor with a dehydrating liquid having a limited water solubility, and drying and firing the resulting gelled microcapsules. For example, an aqueous titania sol is added to an agitated body of n-butanol to form a dispersion of droplets of said sol and water is rapidly extracted from the droplets to form gelled microcapsules; the latter are recovered by filtration, dried, and fired to convert them into transparent, sealed or heat-sealable, non-vitreous ceramic, spherical microcapsules of polycrystalline titania. The microcapsules can be used as fillers for plastic and other composites or filled with a selected solid, liquid or gas for purpose of storing, transporting, or facilitating the use of the same.
