Abstract
Abstract A fluidic programming device for controlling the sequence of a cycle having successive phases. The programming device has a plurality of command connections for communicating with a device to be controlled so that a command signal may be applied to the device being controlled so as to initiate a phase. Information connections communicate between the device being controlled and the programming device to indicate when a phase is completed. Bistable switching devices receive the information from the information connections and supply fluidic command signals through the command connections. When one command signal is delivered to initiate a phase by one of the switching devices it operates to remove the command signal which initiated the preceding phase delivered by another switching device.
