Abstract
The invention provides a control circuit for a pneumatic shift register constituted by phase cells associated with an assembly of two threshold relays, each having a supply input and a control input which inhibits the output when the pressure that it receives is not lower than a pressure threshold which is low with respect to the control threshold of the memory contained in the cell.
