<p>The equipment as designed and constructed is a workable solution to the problem of mixing air and oxygen at selectable oxygen concentrations and flow rates. Control of the flow of the individual gases is adequate ...

The effect of surface finish on the transfer of polychlorotrifluoroethylene (PCTFE) to mild steel was studied using a radio-tracer technique. A pin-on-disk apparatus was used in conjunction with neutron activation of ...

The effect of normal load, contact velocity, and dwell time on the coefficient of adhesion at slip in braking was investigated. A test rig that simulated locomotive wheel/rail interactions was used for the experimentation. ...

Second virial coefficient data for many pure substances with both spherical and nonspherical molecules are used to determine the characteristic parameters of two different three-parameter potential functions. Parameters ...

A microcomputer based system is described that controls the operation of a dual chamber, diaphragm-type pneumatic blood pump in both open-loop and closed-loop modes. The open-loop mode of operation allows selection of ...

A facility for the investigation of stall flutter in aircraft engine compressors and fans was designed. Stall flutter was achieved in the test fan and verified through sonic and photographic methods. The frequency components ...

A study was undertaken to determine the problems involved in applying wind-produced electric energy toward the needs of an apple storage facility, and to design an appropriate energy system. Fruit requirements, wind generator ...

Static pressure and mean velocity data were obtained in a relaxing shear driven three-dimensional incompressible turbulent boundary layer flow produced by a swept rectangular step. The nominally 10 cm (4 in.) thick boundary ...
