Abstract
334,720. Gleichmann, W. Sept. 20, 1929. Fused quartz. - A method of preparing fused silica free from bubbles consists in feeding pieces of rock crystal, which have been preheated to about 600‹ C., into the flame of an oxyhydrogen blowpipe, so that they are projected by the flame against a surface where they gather to form a fused mass. The nozzle 2 of the blowpipe is fitted into an opening in the wall of a muffler furnace 1, and a funnel 3 is fitted into an opening above the nozzle 2. Pieces of rock crystal 7. stored in a hopper 8, are allowed to fall into an enlargement 5 formed on the higher end of an inclined tube 4. This tube is journaled in bearings 9, 10 and can be rotated by suitable means. The pieces of quartz move along the tube 4, and during their journey they are heated by the flame from a blowpipe 12 which is directed along the interior of the tube in opposite direction to that in which the pieces of quartz are moving. The hot quartz falls through the funnel 3 and is projected by the blowpipe jet 13 against the opposite wall of the furnace where a plastic mass 14 of fused quartz is built up. This is removed from time to time by gathering it on a tool.
