Abstract

In this device, one or more globules 10 of liquid are indexed around a closed path, not shown. The liquid is one having a high surface tension. such as mercury. The closed path is defined by a plurality of cavities such as 0 and 1. These are interconnected via restricted passages and made of materials, like glass, that are not wetted by the liquid.

Fluid Counter

In this device, one or more globules 10 of liquid are indexed around a closed path, not shown. The liquid is one having a high surface tension. such as mercury. The closed path is defined by a plurality of cavities such as 0 and 1. These are interconnected via restricted passages and made of materials, like glass, that are not wetted by the liquid.

To add, a steady fluid bias stream is supplied via duct 12 toward duct 13. A counting fluid pressure pulse is supplied via duct 14 across cavity 0 to duct 15 and then to duct 16. Fluid from 16 diverts the flow from 12 in the direction 17 and against the liquid in cavity 1, for displacing the liquid rightward from the cavity. Excess fluid escapes via ducts 13 and 18.

To subtract, the globules of liquid are indexed leftward. A steady bias stream is supplied from 13 to 12. Counting pulses are supplied from duct 19 via duct 20, assuming cavity 1 is empty, and duct 18. The streams from 13 and 18 collide producing a stream 21 for forcing a globule, assumed now to be in cavity 0, leftward. Excess fluid is exhausted via 12 and 16.

During addition, fluid is exhausted via 18, junction 22 and exhaust duct 23. However, during subtraction, pressure fluid flows from 20 into 18 and fluid does not flow into 23. Junction 22, therefore, provides a valve or gate comprising three intersecting fluid ducts 18, 20 and 23. These are arranged so that fluid flowing toward junction 22 along one duct 20 enters a second duct 18. Flui...
