    Abstract: A pneumatic unit ventilator control system utilizing a diaphragm logic memory circuit for winter-summer changing over to allow the running of a single main from the pressure source to the units. Depending upon the magnitude of the main pressure input to the memory circuit, and upon previous alterations of the main pressure, either summer or winter control will be achieved. Recycling means are included in the system to assure the return of the system to the desired mode of operation after a fluid pressure failure or a changeover from one mode of operation to another.

    Abstract: A PNEUMATIC RELAY UTILIZING DIAPHRAGM LOGIC FOR PROVIDING AN OUTPUT PRESSURE TO A FRESH AIR DAMPER MOTOR OR THE LIKE. THE DAMPER IS HELD CLOSED UNTIL THE INPUT PRESSURE TO THE RELAY REACHES A FIRST LEVEL WHEREUPON THE DAMPER IS OPENED TO A PRESELECTED POSITION ADMITTING A PRESELECTED PERCENTAGE OF FRESH AIR, WHICH POSITION IS MAINTAINED UNTIL THE INPUT PRESSURE REACHES A PRESELECTED SECOND LEVEL, WHEREAFTER THE DAMPER CONTINUES TO OPEN AS THE INPUT PRESSURE CONTINUES TO INCREASE UNTIL 100% FRESH AIR IS ADMITTED.

    Abstract: A pneumatic pressure inverter with pilot bleed utilizing diaphragm logic to augment the supply and exhaust functions whereby a fast response and a linear output is achieved. The sum of the branch pressure input and the output pressure is continuously held equal to the main pressure input.
