    摘要： A PLURALITY OF SEPARATE PNEUMATICALLY OPERATED ACTUATORS DISPOSED IN ALIGNED AND ABUTTING RELATION TO PROVIDE A LINEAR POSITIONING UNIT HAVING OPPOSED ENDS WITH EACH ACTUATOR BEING INDIVIDUALLY OPERABLE TO LINEARLY EXTEND ITSELF WHEN ACTUATED AND THEREAFTER TO LINEARLY COLLAPSE ITSELF WHEN DEACTUATED WHEREBY ONE END OF THE UNIT WILL BE CORRESPONDINGLY LINEARLY EXTENDED RELATIVE TO THE OTHER END THEREOF AND THEREAFTER BE LINEARLY COLLAPSED RELATIVE TO THE OTHER END THEREOF. A CONTROL DEVICE BEING OPERATIVELY INTERCONNECTED TO THE ONE END OF THE POSITIONING UNIT TO BE CONTROLLED IN RELATION TO THE POSITION OF THE ONE END RELATIVE TO THE OTHER END THEREOF AND CONTROL

    MEANS FOR DIRECTING A SOURCE OF PNEUMATIC FLUID TO AT LEAST ONE OF THE ACTATORS TO EXTEND THE ONE END OF THE UNIT BY THE DEGREE OF ACTUATION OF THE ONE ACTUATOR AND FOR THEREAFTER DISCONNECTING THE SOURCE FROM THAT ONE ACTUATOR TO COLLAPSE THE ONE END OF THE UNIT BY THE DEGREE OF DEACTUATION OF THE ONE ACTUATOR.

    摘要： A plurality of separate pneumatically operated actuators disposed in aligned and abutting relation to provide a linear positioning unit having opposed ends with each actuator being individually operable to linearly extend itself when actuated and thereafter to linearly collapse itself when actuated and thereafter to linearly collapse itself when deactuated whereby one end of the unit will be correspondingly linearly extended relative to the other end thereof and thereafter be linearly collapsed relative to the other end thereof. A control device being operatively interconnected to the one end of the positioning unit to be controlled in relation to the position of the one end relative to the other end thereof and control means for directing a source of pneumatic fluid to at least one of the actuators to extend the one end of the unit by the degree of actuation of the one actuator and for thereafter disconnecting the source from that one actuator to collapse the one end of the unit by the degree of deactuation of the one actuator.

    摘要： A pneumatic control system having a source of control fluid providing two different control pressure levels for respectively switching the control device of the system from one operating condition thereof to another operating condition thereof, the control device comprising a pair of condition controller means each having a sensor and a bleed-type pneumatic valve operated thereby together with relay means operatively interconnected to the source for directing a branch signal of the control fluid to the source for directing a branch signal of the control fluid to a pneumatically operated device in relation to a pilot signal directed to a pilot chamber of the relay means by one of the control means. A pressure responsive means is provided for switching the system from one condition controller means to the other in relation to the pressure level of the source, and a reset means is provided for overriding the pressure responsive means.
