Abstract: A process and apparatus for preparing anisotropic metallic and ceramic compositions or material includes floating zone melting of eutectics and orientation of eutectoids, as well as melting, frittering, or homogenization of the eutectoids prior to orientation. The process includes solidification of a eutectic in the presence of a thermal gradient while displacing the solidification front of the eutectic along the direction of the gradient and orienting the solid eutectoid which results by imposing a direction of growth on it by displacement of the composition itself or the temperature gradient. The eutectoids are then prepared in a reactive atmosphere within a container and the surface thereof treated in gaseous atmosphere, after which the materials are compacted by displacing them again. The apparatus for performing the process includes a double heating and cooling system and structure for translating and rotating these systems. It additionally includes a support plate for supporting the elements being oriented, the plate being attached to a displacement shaft. Electronic controls for all of the structures are connected to temperature and displacement sensors.

Date Sep. 13, 1984.The compression molding of sections (15), bars, molded articles, or similar, consisting of vegetable particles mixed with binding media was uneconomical, because the relatively short molding time was overlapped by the disproportionate curing time. In order to considerably improve upon this deficiency, the inventor proposes to feed the molded section (15), or similar, along its longitudinal axis into a curing unit, while the sections (15) between the molding jaws (3 through 6) should remain in clamped position. The molding jaws (3 through 6), together with the cured section (15), are then returned through the press and the section is ejected after the unlocking of the molding jaws (3 through 6). Within the framework of the cyclic work, the individual operating processes can be adjusted to one another.
