“…Gravitational differential settling of the mixture tends to segregate grains in the compress, and some degree of cold welding occurs immediately upon formation of the powder compress which geqerates internal frictions that strongly impede further compaction. Considerable theoretical and practical analyses already exist to assist in understanding the packing of powders (Dexter and Tanner, 1972;Criswell, 1975;Powell, 1980aPowell, , 1980bShahinpoor, 1980;Spencer and Lewis, 1980;Visscher and Bolsterzi, 1972).…”

The painting was created by Mr. Rick Guidice. Jr captures the spirit of the space missions described in this study. In the center of the picture are human beings who, we believe, will continue to play a controlling role in future space missions. To the right of the circle are two space systems representing a partially automated Space Manufacturing Facility which would eventually utilize non terrestrial resources. In the upper-right corner is Saturn attended by its largest natural satellite Titan, the proposed destination of our advanced space-exploration mission. The upper-left corner depicts the deepest reaches of the Cosmos that humans someday may explore. At center left is the Earth, which is under intensive study by an intelligent Earthsensing information system that is able to obtain and deliver data in afar more effective manner than present-day methods. In the lower left corner, a lunar manufacturing facility rises from the surface of the Moon. Someday, such a factory might replicate itself, or at least produce most of its own components, so that the number of facilities could grow very rapidly from a single seed. / iii Research and Development in Artificial IntelligenceAt present, there is a great deal of Al theoretical research (and in some cases practical development) in progress at several institutions in the United States and throughout the world.

The size distribution of particles is of importance to a wide variety of particulate systems in the chemical process industries. The compacting and sintering behavior of metallurgical powders, flow characteristics of granular materials, hiding power of paint pigments, and the combustion efficiency of coal and sprayed liquids all depend on particle size. The various means of data representation in particle size measurements are defined and sampling procedures are presented. Methods of size measurement ranging from the historical yet still useful sieving, through the use of modern instrumentation such as laser diffraction equipment and optical counters, are discussed.
