Method of making glass filters

Claim 1

A METHOD OF MAKING A GLASS FILTER COMPRISING THE STEPS OF THREADING A METALLIC WIRE THROUGH A GLASS CAPILLARY, HEATING AND DRAWING THE GLASS CAPILLARY OVER THE WIRE REDUCING THE DIAMETER OF THE GLASS CAPILLARY; CUTTING THE GLASS COVERED WINE INTO LENGTHS, CUTTING PORTIONS OF SOLID GLASS ROD OF DIAMETER SUBSTANTIALLY EQUAL TO THE GLASS COVERED WIRE INTO LENGTHS EQUIVALENT TO THE CUT LENGTHS OF THE GLASS COVERED WIRE, CONFINING SAID GLASS COVERED WIRE LENGTHS AND GLASS ROD LENGTHS IN A PREDETERMINED PATTERN AND IN JUXTAPOSED AXIAL PARALLEL ALIGNMENT, AND SUBJECTING THE RESULTANT ASSEMBLY OF GLASS RODS AND GLASS COVERED WIRE LENGTHS TO SUFFICIENTLY HIGH TEMPERATURES TO MELT THE WHOLE TO A HOMOGENEOUS MASS, SLICING SAID MASS TRANSAXIALLY OF SAID WIRE LENGTHS AND REMOVING SAID WIRE IMMERSION OF THE SLICED PORTION IN AN ACID BATH REACTIVE WITH THE METAL OF THE WIRE TO FORM A SOLUBLE SALT THEREOF.
