VERFAHREN ZUM HERSTELLEN VON SPHAERISCHEN GEGENSTAENDEN.

摘要

A process for manufacturing spherical objects comprises ejecting into a reaction medium layer a predetermined amount of liquid material to be made into spherical objects and allowing the spherical mass produced by the ejection to react to be set while floating in the reaction medium layer, the reaction medium layer being restricted by a blocking and protective liquid layer having a smaller specific gravity than that of the reaction medium layer and located above the level of the ejection and another blocking and protective layer having a greater specific gravity than that of the reaction medium and located below the level of the ejection.
