Abstract
Abstract A pneumatic control assembly comprising a plurality of control valve printed circuit board pneumatic connectors disposed in a card cage in communication with a like number of control logic manifolds fixed to the card cage. The control logic manifolds are programmed to provide the actual control functions to the associated apparatus thereby permitting the conrol valve printed circuit board pneumatic connectors to be identical.

Claim 2
Dependent Claim
97 words
In a pneumatic control system for providing control functions to an associated apparatus, a card cage having having a back plate and a plurality of card slots permanently fixed to said apparatus, a like plurality of control logic manifolds fixed to said back plate for respective ones of said card slots, each of said control logic manifold being individually pneumatically programmed to perform specific control functions, a like plurality of identical control valve printed circuit board pneumatic connectors removably disposed in each of said card slots in pneumatic communication with respective ones of said control logic manifolds.
Claim 3
Dependent Claim
66 words
In a pneumatic control system according to claim 1 wherein each of said control valve printed circuit board pneumatic connectors comprises, a printed circuit board, at least one solenoid operated valve mounted on said printed circuit board, a pneumatic connector mounted on said printed circuit having a first face continguous to said solenoid operated valve pneumatically connecting said solenoid operated valve to said control logic manifold.
Claim 4
Dependent Claim
52 words
In a pneumatic control system according to claim 2 wherein, said solenoid operated valve includes a normally open port, a normally closed port and a common port, said common port connected to said normally open port when said valve is unactuated and to said normally closed port when said valve is actuated.
Claim 5
Dependent Claim
46 words
In a pneumatic control system according to claim 3 wherein, said pneumatic connector includes conduits extending through said first face and terminating at a second face for pneumatically connecting said normally open port, said normally closed port and said common port to said control logic manifold.
Claim 6
Dependent Claim
54 words
In a pneumatic control system according to claim 4 wherein, said control logic manifold includes ports pneumatically connected to said normally open port, said normally closed port, and said common port via said pneumatic connector with only said common port extending through said control logic manifold into said apparatus for controlling a function therein.
Claim 7
Dependent Claim
36 words

Claim 8
Dependent Claim
57 words
In a pneumatic control system according to claim 6 including means for securing said face of said control logic manifold against said second face of said pneumatic actuator and means for forming airtight fittings between the ports terminating at said second face of said pneumatic connector and the ports at the face of said control logic manifold.
Claim 9
Dependent Claim
42 words
In a pneumatic control system according to claim 5 wherein said control logic manifold includes, three channels extending through said control logic manifold, each of said three channels connected to a selected one of said ports in accordance with a predetermined program.
Claim 10
Dependent Claim
42 words
In a pneumatic control system according to claim 6 wherein said control logic manifold includes, three channels extending through said control logic manifold, each of said three channels connected to a selected one of said ports in accordance with a predetermined program.
Claim 11
Dependent Claim
42 words
In a pneumatic control system according to claim 7 wherein said control logic manifold includes, three channels extending through said control logic manifold, each of said three channels connected to a selected one of said ports in accordance with a predetermined program.
