Abstract

A hydraulic jack is connected to the stopper rod and selectively supplied with fluid for raising and lowering the rod. An effort transduces produces a temposal control signal when it detects the variation of effort in the rod when it contacts the nozzle, and a hydraulic distributor simultaneously depressurises the jack locks the stopper rod, and is activated by the control signal at the expiry of the time delay.
