Abstract

Apparatus consists of known means of attachment to and disconnection from the drill string. An intermediate transmission element is a first memory and there is a maximum control type of coupling, and a transmission element serving as a second memory. Specif., the disconnection may be performed automatically by a detector which responds to the removal and return of the weight of the drill string from and to the hook.
