The Caltech Intermediate Form for LSI Layout Description

A passageway for hydraulic or other fluid is formed by rigid tubes within a snorkel-mast hoist-piston so as to connect operating means of the snorkel-mast head-valve with a source of operating fluid so that both snorkel-mast hoist and head-valve may be operated in combination and with only two rigid fluid lines directly connected to the snorkel mast hoist.
