Title: Jiri Vodnansky: Innovator in Centrifugal Casting Technology
Introduction
Jiri Vodnansky is a notable inventor based in Prague, Czech Republic. He has made significant contributions to the field of centrifugal casting technology, particularly in the production of contact lenses. With a total of 2 patents, Vodnansky's work has advanced the methods used in this specialized area of manufacturing.
Latest Patents
Vodnansky's latest patents include a "Method and apparatus for spreading monomer mixtures in molds for the centrifugal casting of contact lenses." This innovative method involves rotating molds containing a monomer mixture around their axis at a frequency of 0.5 to 5 revolutions per minute. The molds are periodically tilted between extreme positions, enhancing the spreading of the monomer mixture. The angles of tilt range from 30 to 60 degrees in one extreme position to 70 to 100 degrees in the other, with the tilting frequency being significantly lower than the rotation frequency. Another patent, titled "Method and apparatus with automatic feed means for centrifugally casting," describes a centrifugal casting device that features a rotatable polymerization column. This device accommodates multiple vertically aligned molds and includes a mold-dispensing magazine that dispenses molds one at a time into the polymerization column.
