    Abstract: The present invention provides a novel, optionally surfactant-free process for controlling particle number, particle size, and/or particle size distribution. The method of the invention also significantly improves monomer to polymer conversion rates, as well as, increases the level of polymer solids which can be emulsified/dispersed in water without polymer flocculation. Specifically, the improved process provides an aqueous dispersion of up to about 48% polymer solids in water in the absence of surfactant. The resulting fluoropolymers dispersions may be used in resin and coating applications.

    Abstract: Apparatus and method are described for interoperatively determining, during a trailing procedure conducted in connection with total hip arthroplasty, a combination of neck length and femoral head offset required in a femoral component for establishing appropriate hip mechanics in a prosthetic hip joint to be implanted at an implant site. A trial femoral head is coupled for selective movement relative to a femoral stem component to move the trial femoral head longitudinally and laterally relative to a predetermined direction among selected combinations of trial distance and trial offset to evaluate hip mechanics and determine interoperatively an appropriate combination of trial distance and trial offset corresponding to the combination of neck length and femoral head offset required in the prosthetic hip joint.
