Pressure of Light Used as Restoring Force on an Ultramicrobalance,ble Varian ultrahigh-vacuum chamber with a pressure capability of 10. torr, has a sensibility of 10. g. The range and the sensitivity of the balance can be selected by external control. Since using magnetic restoring in the vicinity of the Vaclon® pump would require extensive shielding, the pressure

Wireless Temperature Measurement of a Sample in Vacuum, in which the sample temperature causes a change in frequency of the infrared emitted from a gallium arsenide photodiode. The oscillator unit is mounted in a small hermetically sealed box which in turn is moiunted on the microbalance as part of the sample weight. A thermistor is buried in the sample

Thermal Degradation of Piperazine Copolyamides,ified hangdown tube and thermocouple assembly. Experiments were carried out with block copolymers of terephthaloyl trans-2,5-dimethylpiperazine / isophthaloyl trans-2,5-dimethylpiperazine (abbreviated as t-2,5-DiMePipT / t-2,5-DiMePip-I), terphthaloyl trans-2,5-dimethylpiperazine / sebacyl trans-2,5

Thermal Degradation of an Anhydride-Cured Epoxy Resin by Laser Heating,on tube of a Cahn RG Electrobalance®. The beam was transmitted through an IRTRAN-4 entrance window into the system. Calibration of the laser was made with respect to temperatures attained by the platinum crucible and measured with a chromel — alumel thermocouple and a recorder. The electrobalance, w

Adsorption Studies with a Bakeable Quartz Automatic Recording Ultramicrobalance,ngmuir kinetics with a sticking coefficient of 0.38. This agrees with measurements made by flash filament desorption. Adsorption of ethylene is more complicated, but the results are consistent with more detailed mechanistic studies performed in this laboratory on 〈111〉 single-crystal platinum.
