Two check valves prevent reverse flow through pilot-operated relief valves of differential area piston design. Title valves control pressure flow to ensure that the piston dome pressure is always at least as great as the main relief valve discharge pressure.
Spectral line-reversal measurements of excitation and electron temperature in shock tube
Spectrum line reversal measurements of free electron and coupled nitrogen vibrational temperatures in expansion flow of shock tube
Reversal errors of machine tool servomechanisms, and feedback control circuits
Spectrum line reversal measurements of excitation temperature of Na atoms in expansion flows of shock-heated Ar and one percent nitrogen plus Ar mixtures
Plasma measurements in cesium electron bombardment ion engine indicate that reversed cathode-anode configuration improves radial ion distribution
Population temperatures within argon-calcium plasma generated by reflected aerodynamic shock determined by spectral line-reversal method
Successive reversals involving cues of brightness and orientation
FORTRAN 2 computer program calculates maximum estimates of a monotonic non-decreasing response function. The program uses the method of reversals algorithm which applies to the analysis of univariate or multivariate sensitivity experiments.
Fatigue of reinforced concrete due to complete reversal loading
Gamma-ray angular correlation experiment of time reversal invariance
Large scale low speed wind tunnel tests of delta winged supersonic transport model to determine aerodynamic effects of forward and reverse thrust
Plasma measurements in cesium electron bombardment ion engine indicate that reversed cathode-anode configuration improves radial ion distribution
Reverse magnetization spike domains analyzed for nucleation and growth
