Porous gas diffusion electrodes design for electrochemical energy converters, noting contribution of theory of electrode kinetics
Temperature profiles variability for data obtained by rocketsonde thermistors launched with small time and spatial separation
Mercury-column electrochemical coulometer is a linear ampere-hour integrating device consisting of a sealed glass tube containing two columns of mercury separated by a gap containing an electrolyte. The drive circuit uses operational amplifier techniques to match nonlinear charge-discharge characteristics of an alkaline battery.

Electronic circuit for monitoring excessive ripple voltage on dc power lines senses voltage variations from few millivolts to maximum of 10 volts rms. Instrument is used wherever power supply fluctuations might endanger system operations or damage equipment. Device is inexpensive and easily packaged in small chassis.
Circuit, when used with decision table, permits relatively unskilled personnel to maintain effective quality control. Design determines required changes in calibration intervals. Interval readings are recorded to nearest integer, making high precision unnecessary. Specific required performance-history information is discussed.
