Abstract
A device for automatically carrying out the withdrawal and deposition of core samples of semi-solid media in which one or more hollow punches are mounted for movement in three mutually perpendicular directions, so that the punch can be brought above and lowered into the media, a vacuum applied to suck the media into a chamber in the punch, the punch then being raised and moved to a position above a second media, the vacuum then being removed and compressed air applied after the punch has been lowered over the other media, thereby to push the sample removed from the first media from the punch. The operations can all be controlled automatically.
