SAMPLE REMOVING TOOL AND METHOD THEREFOR

摘要

A pair of openings are formed using an EDM technique. A pair of clamps are inserted into the openings and moved toward each other until such time as the inboard edges of the two openings are engaged. A pair of EDM cutters are used to cut a pair of slots which extend from one opening to the other. Upon completion of these slots, the sample, which remains clamped between the two clamps, is withdrawn and lowered back down the conduit to a remote collection point.
