Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
70 words
THE PROCESS FOR PREPARING OXIDE GEL MICROSPHERES FROM A STABLE HYDROUS OXIDE SOL WHICH COMPRISES FORMING SAID SOL INTO DROPLETS IN AN ORGANIC LIQUID HAVING A WATER SOLUBILITY OF 0.3 TO 10 VOLUME PERCENT AND A SOLUBILITY IN WATER LESS THAN 1 VOLUME PERCENT AND CONTAINING A SURFACE-ACTIVE AGENT, MAINTAINING THE RESULTING DROPLETS IN CONTACT WITH SAID LIQUID UNIT SAID DROPLETS ARE CONGEALED AND RECOVERING THE RESULTING CONGEALED SPHERICAL PARTICLES.
Claim 2
Dependent Claim
70 words
THE PROCESS FOR PREPARING OXIDE GEL MICROSPHERES FROM A STABLE HYDROUS OXIDE SOL WHICH COMPRISES FORMING SAID SOL INTO DROPLETS IN AN ORGANIC LIQUID HAVING A WATER SOLUBILITY OF 0.3 TO 10 VOLUME PERCENT AND A SOLUBILITY IN WATER LESS THAN 1 VOLUME PERCENT AND CONTAINING A SURFACE-ACTIVE AGENT, MAINTAINING THE RESULTING DROPLETS IN CONTACT WITH SAID LIQUID UNIT SAID DROPLETS ARE CONGEALED AND RECOVERING THE RESULTING CONGEALED SPHERICAL PARTICLES.
Claim 3
Dependent Claim
177 words
THE PROCESS FOR PREPARING ACTINIDE CARBIDE MICROSPHERES OF A CONTROLLED SIZE IN THE RANGE OF 50 TO 1000 MICRONS IN DIAMETER FROM A STABLE HYDROUS ACTINIDE OXIDE SOL WHICH COMPRISES INTIMATELY MIXING SAID SOL WITH FINELY DIVIDED CARBON, CONCURRENTLY INTRODUCING A FINE STREAM OF THE RESULTING CARBON-CONTAINING SOL AND A SURROUNDING STREAM OF AN ORGANIC LIQUID HAVING A WATER SOLUBILITY OF 0.3 TO 10 VOLUME PERCENT AND A SOLUBILITY IN WATER LESS THAN 1 VOLUME PERCENT AND CONTAINING A SURFACEACTIVE AGENT INTO A DROPLET-FORMING ZONE, THE FLOW RATE OF SAID ORGANIC LIQUID BEING SUBSTANTIALLY HIGHER THAN THE FLOW RATE OF SAID CARBON-CONTAINING SOL AND ADJUSTED TO A PREDETERMINED VALUE IN RELATION TO SAID SOL FLOW RATE WHEREBY CARBON-CONTAINING SOL DROPLETS OF A PREDETERMINED SIZE ARE FORMED, PASSING THE RESULTING DROPLETS DOWNWARD THROUGH A VERTICALLY EXTENDING CONGEALING ZONE, COUNTERCURRENTLY PASSING A SECOND STREAM OF SAID ORGANIC LIQUID UPWARD THROUGH SAID CONGEALING ZONE, THE DIMENSIONS OF SAID CONGEALING ZONE AND THE FLOW RATE OF SAID SECOND STREAM BEING ADJUST TO MAINTAIN THE RESULTING CONGEALING MICROSPHERES IN SUSPENSION UNTIL THE

Claim 5
Dependent Claim
66 words
A PROCESS FOR MAKING INORGANIC MICROSPHERES FROM A STABLE HYDROSOL COMPRISING FORMING SAID HYDROSOL INTO DROPLETS IN AN ORGANIC LIQUID HAVING A WATER SOLUBILITY OF 0.3 TO 10 VOLUME PERCENT AND A SOLUBILITY IN WATER LESS THAN 1 VOLUME PERCENT AND CONTAINING A SURFACE-ACTIVE AGENT, MAINTAINING THE RESULTING DROPLETS IN CONTACT WITH SAID LIQUID UNTIL SAID DROPLETS ARE CONGEALED AND RECOVERING THE RESULTING CONGEALED SPHERICAL PARTICLES.
