1,214,771. Fluidic circuits. CORNING GLASS WORKS. 16 April, 1969 [23 April, 1968], No. 19379/69. Heading G4P. A fluidic circuit having n control inputs gives an output dependent on the number of inputs energized. In a first embodiment, Fig. 1, signals on control inputs C of monostables 12, 14, 16 switch jet P from output B to output A. Outputs B are combined at input C of bi-stable 18 and outputs A are combined at D, so that bi-stable 18 gives an output B only when there are less than two control signals present simultaneously. By replacing monostables 12, 14, 16 by bi-stables similar operation occurs in response to sequential input signals. Bi-stable 18 may be replaced by a proportional amplifier, giving an output proportional to the ratio of the number of energized to unenergized control inputs. In the latter modification n may be even. |
