Abstract

Radioactive logging tool Sonde is linked to the electronic feeder for passing the signals to the analyser by means of a flexible tie bar which is hinged to both and can enclose their linking cable. A spring fitted on teh sonde presses it permanently to the hole wall and operates in the plane in which the sonde can itself move in relation to the electronic feeder.
