DEFINITION
Classification: 235/200
(under subclass 61) Subject matter utilizing fluid which represents information content; the system as a whole being specialized to a calculating function and having (1) fluid flow varying components which are connected by fluid storage or flow passages which, for example, act as a "feed back", a "carry" between components, distribute pulsed flow between components or act as information memory means or (2) one or more means utilizing a fluid, combined with a calculation value indicator.

137, Fluid Handling,
803+, for devices of more general application in which fluid flow of one stream is effected by (1) fluid contact with another stream or by (2) use of an energy field and see the notes to Class 137, subclass 803 for the line between classes.
341, Coded Data Generation or Conversion, appropriate subclasses for code converters which are electrical at least in part.
364, Electrical Computers and Data Processing Systems, appropriate subclasses for electrical calculating systems in which an electrical signal and a fluid stream representing calculating information content form components of a systems.
