Process and apparatus for polymerized surface coating

Claim 1

A PROCESS OF FINISH COATING AN ARTICLE COMPRISING THE STEPS OF (A) SUBJECTING TO HIGH ENERGY IRRADIATION A SOLUTION OF A POLYMERIZABLE COATING MATERIAL AND A VOLATILE THINNER, IN WHICH THE MATERIAL AND ENERGY ARE OF TYPES SUCH THAT THE IRRADIATION WILL EXCITE THE MOLECULES OF MATERIAL TO A STATE CAPABLE OF POLYMERIZING THE MATERIAL UPON SUBSEQUENT REMOVAL OF THINNER, AND IN WHICH THE CONCENTRATION OF COATING MATERIAL IN THE THINNER IS LOW ENOUGH TO SEPARATE THE EXCITED MOLECULAES OF THE MATERIAL SUFFICIENTLY TO PREVENT POLYMERIZATION FROM TAKING PLACE UNTIL SUBSEQUENT REMOVAL OF THINNER, (B) TRANSPORTING THE IRRADIATED SOLUTION INTO PROXIMITY WITH SAID ARTICLE, (C) ELECTRICALLY ISOLATING SAID SOLUTION FROM GROUND AND FROM SAID ARTICLE DURING THE STEPS OF IRRADIATION AND TRANSPORTION, THEREBY PREVENTING PREMATURE DISSIPATION OF ENERGY FROM SAID MATERIAL, (D) COATING SAID ARTICLE WITH SAID SOLUTION WITHIN SUCH TIME FOLLOWING IRRADIATION THAT USEFUL ENERGY IN SAID MATERIAL HAS NOT HAD AN OPPORTUNITY TO LEAK OFF, AND (E) FLASHING OFF SAID THINNER SHORTLY THEREAFTER WHEREBY POLYMERIZATION OF SAID MATERIAL OCCURS WHEN THE MOLECULES THEREOF ARE BROUGHT CLOSER TOGETHER ON EVAPORATION OF SAID THINNER.
