Abstract: A process is provided that permits the rapid quenching of molten ceramics by passing a flow of the molten ceramic into a turbulent fluid flow such that the flow is broken up into particles which then solidify as they pass into and through a cyclone and are finally separated from the fluid flow and collected as dry particulate ceramic materials.

Abstract: An apparatus including an elongate flexible strip longitudinally aligned, including a first and second aperture directed through the strip adjacent a forward and rear end of the strip to receive a flexible tether line therethrough to secure a stack of frangible sheets against a support platform. A modification of the invention includes removal grommets directed through the openings to vary the effective diameter of each opening, and further may include a selectively securable positioning member onto a bottom surface of the strip to assist in alignment of the strip adjacent a corner of the aforenoted stack.

Abstract: A collapsible combined table and seat assembly including an improved collapsible linkage for rigidly supporting the seats and for supporting the table on the seats. The linkages rely on knock down rigid triangular structures, one for supporting each seat and one extending between the seats and the table top.
