Abstract: Process for obtaining monodisperse microspheroidal particles, comprising spraying an electrostatically charged gellable liquid material through a spraying orifice and into a chamber, so as to produce macrodrops which break up into microdrops which fall in the chamber and within which gelling is produced after spraying. The microspheroidal particles thus obtained can be collected on a solid surface or preferably in a liquid medium and find application in the manufacture of silica-based microspheroidal particles. These microspheroidal particles can be employed as catalyst supports for alpha-olefin polymerization.

Abstract: Gel beads of microbial cells or enzymes enclosed in gels are produced by forming a surface liquid stream of a gelling agent flowing from the center toward the peripheral wall of a vessel containing the gelling agent by a lower rotor on the liquid surface of the gelling agent, and dispersing a colloidal suspension of microbial cells or enzymes into a droplets by an upper rotor and allowing the dispersed droplets to fall onto the surface liquid stream, thereby contacting the droplets with the gelling agent. The lower and upper rotors may have vanes radially provided at a periphery of a lower and upper sides, respectively. In place of separate rotors, a single rotor may be used with lower and upper surfaces which respectively provide the functions of the lower and upper rotors. The lower and upper surfaces may also have radially provided vanes. The lower and upper rotors or the lower and upper surfaces of a single rotor are spaced sufficiently from each other so that gelling agent is not splashed by the lower rotor or surface onto the upper rotor at surface. The bead size of gel beads can be adjusted by adjusting the number of revolutions of the rotor, and gel beads of smaller bead size can be produced in a mass production scale without any problem of nozzle clogging and without using a number of nozzles of smaller size.

Abstract: A simplified internal gelation process for the preparation of gel spheres of nuclear fuels. The process utilizes perchloroethylene as a gelation medium. Gelation is accomplished by directing droplets of a nuclear fuel broth into a moving volume of hot perchloroethylene (about 85.degree. C.) in a trough. Gelation takes place as the droplets float on the surface of the perchloroethylene and the resultant gel spheres are carried directly into an ager column which is attached to the trough. The aged spheres are disengaged from the perchloroethylene on a moving screen and are deposited in an aqueous wash column.

Abstract: Spheroidal polymer beads having a uniform size are prepared by polymerizing uniformly sized monomer droplets formed by vibratory excitation of a laminar jet of monomeric material flowing in a gas phase. For example, a laminar jet of a monomer mixture comprising styrene, divinylbenzene and a polymerization initiator can be subjected to vibratory excitation and the resulting monomer droplets polymerized to yield copolymer beads having a narrow particle size range distribution. The copolymer beads can be employed in applications where beads having diameters of 5 .mu.m to 100 .mu.m are useful.

Abstract: Ceramic pellets, which may have, or not, nuclear fuel materials embedded therein, are formed by first preparing a gel by precipitation of metallic salts from solutions of their compounds at a concentration of at least 10 grams per liter, said solutions being added dropwise to a coagulation bath which contains, for example, ammonium or sodium hydroxide, whereafter the precipitated gel are fired, in one or two stages, to precondition them prior to the compaction to form the final pellets which are subsequently sintered at an appropriate temperature.
