Abstract
A combination of means to detect rotation of a pipe string and means to detect flow of fluid through a pipe string is utilized to cause down hole apparatus to carry out preferred actions if the sequence of rotation rate change and flow rate change is of one character, other activities being carried out if different sequences occur. Alternately, a choice of several actions to be taken by down hole apparatus may be elected by sustaining a flow condition while rotational conditions are manipulated at the earth surface.
