Claim 1
Independent Claim
124 words
METHOD OF TRANSPORTING SOLID PARTICLES DISPERSED IN A LIQUID HAING A DENSITY DIFFERENT FROM THAT OF THE PARTICLES WHILE INHIBITING VERTICAL MIGRATION OF SAID PARTICLES THROUGH THE LIQUID, WHICH COMPRISES THE STEPS OF: (A) FORMING IN SAID LIQUID A COHERENT, INTERLACED, PUMPABLE MATRIX OF A MULTITUDE OF PIECES OF THIN, SOLID MATERIAL WHICH IS SUBSTANTIALLY INSOLUBLE IN SAID LIQUID HAVING THICKNESS UNDER 0.01 MM. AND LENGTHS UNDER 10 CM., BY INTRODUCING INTO SAID LIQUID A SUFFICIENT QUANTITY OF SAID PIECES TO FORM A COHERENT MASS WHICH HAS OVER 90% BY VOLUME OF SPACES, SAID SPACES BEING FILLED WITH SAID LIQUID, AND DISTRIBUTING SAID SOLID PARTICLES WITHIN SAID MATRIX, AND (B) FLOWING THE RESULTING DISPERSION OF SOLID PARTICLES, MATRIX AND LIQUID THROUGH A PIPE LINE.
