Method of making molecular sieves

Claim 1

METHOD OF MAKING SPHERICALLY SHAPED BONDED ZEOLITIC MOLECULAR SIEVES USING CLAY AS BONDING AGENT, WHICH COMPRISES MIXING WATER, MOLECULAR SIEVE MATERIAL AND CLAY IN SUCH PROPORTIONS THAT A VISCOUS MIXTURE IS FORMED WHICH IS IN FLOWING CONDITION WHEREIN THE MICTURE BEHAVES LIKE A LIQUID UNDER SLIGHT MECHANICAL STRESS OR GRAVITY, AND LIKE A SOLID BODY UPON IMPACT AND IN A STATE OF REST; AND CAUSING THE THUS FORMED VISCOUS MIXTURE TO FLOW THROUGH APERTURES OF ABOUT 2-10 MM. DIAMETER AT A RATE SUCH THAT CONTINUOUS STRANDS FLOW THROUGH SAID APERTURES ONTO A MOVING SURFACE COVERED WITH A PULVERULENT MEDIUM, THE SPEED OF MOVEMENT OF SAID SURFACE BEING SUCH THAT THE STRANDS AFTER REACHING THE SAME ARE DIVIDED INTO GLOBULES WHICH ARE COVERED BY THE PULVERULENT MEDIUM, WHEREBY INDEPENDENT GLOBULES OF SUBSTANTIALLY CONSTANT DIAMETER ARE FORMED.
