Tests were made to check the reproducibility of readings from the high- velooity thermocouple (HVTC) and to determains the time necessarr for heat saturation of the thermocouple. The nsw helium recycle conapressor operated without difficulty for over 550 hours at lOOO deg F. Tests revealed that 5000 to 9000 ft/sup 3/ of helium per hour can be circulated through the loop at pressures of 100, 175, and 250 psig, and helium temperatures of 1600 and 2200 deg F. Results of tests with specimens of type-310 stainless-steel tabes, spraycoated with molybdenum and tungsten, indicate that the sprayed coatings provide no additional creep-rupture strength at 2000 deg F. An apparatus was constructed for lifetesting promising commercially-available alloys for use in coal gasification. Tests are continuing with the tungsten tester to determine traces of oxidizing impurities in helium. The helium-heated gasifier was redesigned to accommodate higher pumping rates. In tests on the electrostatic pracipitator at 900 deg F and 5 to 80 psig, more than 99% of the dast was removed from a gas flowing at 5 feet per second. (auth)
