Studies on ultrasonic coalescence of oil-in-water emulsions were continued in series operated annular treatment vessels. Results are in the range expected from Individual operation of the vessels and further geometry modifications are in process. Dissolution of uranium slugs in cadmium at 525 deg C was carried out in the high-temperature controlled-atmosphere ultrasonic treatment furnace. In four hours 30 grams of uranium were dissolved in contrast to none in a non-ultrasonic control. The propagation of ultrasonic energy in various ceramic, stainless steel, and cermet powder slips was estimated. Improvement in the fired density of a cermet composition was observed in preliminary experiments. A major improvement in the surface of alumina extrusion specimens was obtained. The finish was smoother and evidence of drag and surface pitting completely eliminated in contrast to the nonultrasonic control. It was also found that extrusions Could be accomplished at 0.2 wt.% plasticizer which were equivalent to those normally requiring over 2 wt.%. Sub-micron aerosols simulating those expected in the Idaho Falls calciner off-gas system were successfully coalesced in a Multi-stage apparatus. With the use of a standing wave system and low concentrations of additive aerosol, effluent concentration of 0.5 to 0.75 micrograms per cubic foot were attained. Linear velocities in the range of 33 to 325 feet per minute were examined with satisfactory removal of particulate matter. (For preceding period Bee NY02570.) (auth)
