Abstract

1404992 Fluidic systems PROCESS SYSTEMS Inc 11 May 1972 [12 May 1971] 1077/75 Divided out of 1404991 Heading G4P The description is the same as that relating to Figs. 1-4 of the parent Specification. The claims are directed to a digital fluid flow control system in which digital valves control flow between upstream and downstream manifolds, and in which means is provided for rendering the pressure in the upstream manifold insensitive to pressure variations in the downstream manifold by ensuring that flow through the open valves is at sonic velocity.
