ABSTRACT:
A plurality of parallel rows of short flexible tubes lead from a housing. Each row is provided with an elongate bar in which each tube is provided with a transverse fluid passage leading to a port by means of which the respective tube may be connected to an outside fluid conduit. Each elongate bar, by virtue of the flexibility of the tubes, may be pivoted to one side, thereby giving access to connections at interior bars. The structure has particular utility in a system where a plruality of fluid pressure pickups are fed to individual pressure measuring transducers in the housing. Partitions and actuating bladders are interposed between the flexible tubes, so that inflation of a given bladder will pinch off a row of flexible tubes and allow a selected group or row of tubes to be selectively connected to the pickups. In this way a limited number of transducers in the housing may be used to successively measure a much larger number of fluid pressure pickup points, by time sharing use of the transducers.
