Abstract

The upper drawing shows a pneumatic matrix configuration. The matrix comprises sixteen parallel pneumatic lines a... n extending in the X direction and sixteen parallel pneumatic lines a'... n' extending in the Y direction. Lines a'... n' respectively have electromagnetically actuated control valves 1'... 16' for switching low pressure from source line 50 to any of lines a'... n'. Likewise each X-line is connected to source line 50 through an electromagnetically actuated valve 1... 16, respectively. At each of the two hundred fifty-six line crossovers in the matrix, an output actuator valve A is provided which is actuated by inputs from the two lines crossing adjacently to the respective actuator A. If both lines connecting to an actuator A are connected by a valve 1... 16 and a valve 1'...

Pneumatic Matrix

The upper drawing shows a pneumatic matrix configuration. The matrix comprises sixteen parallel pneumatic lines a... n extending in the X direction and sixteen parallel pneumatic lines a'... n' extending in the Y direction. Lines a'... n' respectively have electromagnetically actuated control valves 1'... 16' for switching low pressure from source line 50 to any of lines a'... n'.

Likewise each X-line is connected to source line 50 through an electromagnetically actuated valve 1... 16, respectively. At each of the two hundred fifty-six line crossovers in the matrix, an output actuator valve A is provided which is actuated by inputs from the two lines crossing adjacently to the respective actuator A. If both lines connecting to an actuator A are connected by a valve 1... 16 and a valve 1'... 16' to low pressure line 50, the respective actuator is actuated. On the other hand, if neither or only one of the input lines to an actuator is connected to line 50, the actuator valve is not actuated.

The lower drawing shows an actuator valve A. Valve A is mounted on frame plate 20 and is enclosed in container 25. Input tube 23 connects a pressure source Pl to container 25. Output tube 24 passing through frame 20 also connects to box 25 but is blocked from pressure source P1 by a diaphragm 28. This is normally biased downwardly by coaxial tube springs 26 and 27 that respectively connect to coaxial tubes 21 and 22. Tube 21 connects to one of lines a... n cont...
