Abstract: The present invention provides an improved method and apparatus for curing coatings on optical fibers, without creating additional heat and compromising the manufacturing speed of optical fibers. The present invention uses at least one ultrasonic transducer coupled to a component of the optical fiber draw tower, such as the coating die, curing stage device or sheath, to emit ultrasound to the coating of the fiber. The use of ultrasound with current coating cure techniques, such as UV radiation curing, aids in accelerating the coating cure process through the effects of sonolysis, allowing an increase in current manufacturing speeds of optical fibers.

Abstract: Techniques for precisely controlling the size of particles in a coating solution delivered to a coating apparatus involve continuous classification of coating particle size using a tangential flow filter assembly. The techniques may be particularly useful in the preparation of coating dispersions for manufacture of magnetic recording media. A classification technique makes use of a tangential flow filter assembly that permits delivery of coating particles below a maximum size threshold to a coating path. The filter assembly may be disposed in a circulation path that includes one or more processing devices to reduce the size of coating particles carried by a coating solution. The filter assembly enables coating particles above the maximum size threshold to be recirculated through the circulation path and subjected to repeated processing to reduce particle size to a desired size range.
