Air bearing system supports a shaker system slip table with minimum friction. At each corner of a square of grooves made on the table, a hole is drilled through the table and fitted with air connections. Air pressure is simultaneously fed to the four fittings forming an air bearing.
Evaluating miniature slip ring materials and design techniques for high vacuum operation
Sublimation technique to lubricate slip rings in high vacuum
Neutron activation analysis techniques were employed for the study of the wear and performance characteristics of slip ring and rotor assemblies and of the problems arising from environmental conditions with special reference to surface contamination. Results showed that the techniques could be successfully applied to measurement of wear parameters.
Slip table fixture design for cryogenic and vibration testing of liquid oxygen prevalve and flow meter
First slip time of phase locked loop of arbitrary order shown as solution of first order linear differential equation
Dynamic model for cycle slipping in first order locked loops
Cycle slipping performance of second order phase locked loop
Cycle slipping in first order phase locked loop determined by input carrier plus noise model based on induced steps of plus or minus 2 pi
Magnesium adapter ties in all of the attachment bosses on a horizontal slip table and makes a rigid coupling which terminates in a single row of attachment bosses at the edge of the horizontal plate. This eliminates ineffective dissipation of the driving force in vibration tests.
Influence of number of slip systems operating in magnesium on friction and effect of orientation of crystals on friction behavior
Combined conduction and radiation transfer equations solutions for absorbing-emitting gas, obtaining slip coefficient for diffusion solution correct boundary condition
