English to Spanish Law/Patents Materials (Plastics, Ceramics, etc.) glass coatings

CONTEXT: " Certain example embodiments of this invention relate to techniques for debris reduction when performing edge deletion on coated articles having temporary protective coatings applied thereto. In certain example embodiments, a stationary (at least in operation), enlarged, and higher powered aspirator connected to flexible tubing, which itself has an enlarged diameter, that has a nozzle located proximate to a grinding wheel on an edge deletion unit is provided in connection with an edge deletion table. Advantageously, the edge deletion table and aspirator of certain example embodiments are capable of performing edge deletion and removal of a temporary protective coating substantially simultaneously, e.g., at a common area of interest, during which process the debris produced when edge deletion is performed is controlled and removed from the substrate of interest."

ATTEMPT: "en la zona de interés, en la zona en cuestión".
