Abstract
1348928 Fluidic elements WESTERN ELECTRIC CO Inc 5 July 1971 [6 July 1970] 31301/71 Heading G4P A fluidic unit has two inputs 101, 102 associated nozzles 104, 105, and a number of outputs. As shown there are three outputs. If fluid is present at input 102 only, the jet from nozzle 105 attaches to the lowest wall of the chamber and exits at output 118 (Fig. 3). If fluid is present at input 101 only, the jet from nozzle 101 is directed by the opposite curved wall to exit also at output 118 (Fig. 2). If both jets are present and of equal velocity the jets interact to provide a resultant jet that, aided by the action of cusp 109, exits at 120. However, if the jet from nozzle 105 has substantially greater velocity than that from nozzle 104 the resultant jet takes the path shown and exits at 121. Output 118 represents an EXCL-OR output and output 120 an AND output. If one of the jets is present continuously, e.g. that from nozzle 104, the unit may be regarded as an analog-digital converter since the output from which fluid flows will depend upon the velocity of the jet from nozzle 105. The unit may be used to energize under-pressure and over-pressure alarms connected to outputs 118, 120 in response to variation in the velocity of the jet from nozzle 104, the other jet being of constant velocity.
