发明名称 METHOD OF CORRECTING TYPEWRITTEN IMPRESSIONS
摘要 A method of correcting a typewritten impression comprising the steps of centering an applicator containing a correction liquid and having a liquid outlet and a valve head extending through the liquid outlet for controlling flow of correction liquid through the liquid outlet in overlying relationship relative to a typed impression with said valve head engaging substantially the center of said typewritten impression. Therefore, said correction liquid is ejected from said applicator to form a disc of correction liquid having a ring of greatest thickness adjacent the periphery of said disc and surrounding the impression to be corrected, and then allowing said disc of correction liquid to dry.
