Abstract : The study was undertaken to evaluate the prototype model of a mixed-gas scuba regulator developed by the Detroit Controls Division of the American Radiator and Standard Sanitary Co. for use as a component part of a standard USN mixed-gas scuba. The units stability over long time flow appeared acceptable, but its reproducibility was not. Its flow characteristics as a function of supply pressure was not satisfactory. The constant-mass-flow characteristics with increasing depth at a given supply pressure appear to be acceptable, but when the supply pressure is reduced the flow falls off unacceptably. Continued development of this regulator, while feasible, appears to be rather impractical in view of some of the other developments in this area. (Author)
