  • Pneumatic phase module locking device
    Patent number: 4364414
    Abstract: A locking device, for a pneumatic sequential control phase module, is constituted by an apparatus adapted to be placed between a base and a housing containing a bi-stable memory, and comprises a selector member receiving cancelling signals and auxiliary signals and the output of which is coupled to a locking input of an inhibitor element placed in series with the channel which transmits the control signals for placing the memory in logic state "1".
    Type: Grant

    Assignee: La Telemecanique Electrique
    Inventors: Daniel Bouteille, Hugues Marguet, Eric Petrimaux
  • Pneumatic logic circuit
    Patent number: 4245673
    Abstract: A sequencing logic circuit comprises a blocking means for preventing phase jumps caused by the untimely presence of a release signal. An inhibitor device is placed on one of the channels feeding a storage relay, placed upstream of said release signal, in such a manner as to prevent the transmission thereto of a pressure for placing it in logic state "1." This inhibitor device is actuated by the release signal and does not permit any communication between the latter and the channel controlled.
