Abstract

A high recovery rate binary counter having high-pressure sensitivity and independence to output loading. The counter embodies a bistable fluid amplifier, two exclusive gates, and a fluid pulse device for providing signal pulses of predetermined duration. The outlet of each exclusive gate is connected to opposing control ports of the bistable fluid amplifier while the input to the exclusive gates is connected to the outlet of the pulse device. Feedback is provided from the outlets of the bistable fluid amplifier to the control ports of the exclusive gates. A second embodiment employs AND gates in place of exclusive gates.

The outlet: of each exclusive gate is 235/200, g P g mp- Sens, connected to opposing control ports of the bistable fluid am- R f d plifier while the input to the exclusive gates is connected to 1 e erences I e the outlet of the pulse device. Feedback is provided from the UMTED STATES PATENTS outlets of the bistable fluid amplifier to the control ports of the 3,226,023 12/1965 Horton 137/81.5X exclusive gates. A second embodiment employs AND gates in 3,227,368 1/1966 Jacoby 235/201 place ofexclusive gates,

0 -60 l2 1 l4 1 l 32 38 outlet passage 20, whereupon the flow through feedback passage 64 is terminated and a similar feedback is caused to flow through feedback passage 62 to control nozzle 36 of exclusive gate 12. The remainder of the flow through passage 66 will pass to and be caused to be sensed by utilization device 68.

When the next pulse is transmitted through outlet passage 46 offluid pulse 44 it will similarily pass through both sections of passages 60 and be emitted through

inlet nozzles

32 and 38 of

exclusive gates

12 and 14 respectively. This time, however, that portion of the pulse emitted from inlet nozzle 32 will be deflected by the feedback flow emitted through control nozzle 36 of exclusive gate 12 and be vented, whereas that portion of the pulse emitted through inlet nozzle 38 of exclusive gate 14 will be intercepted by outlet passage 40 and be emitted through control nozzle 26 of bistable fluid amplifier 10. In this manner, the power stream emitted from inlet nozzle 16 of amplifier 10 will flop over from outlet passage 29 to outlet passage 18 whereupon the cycle will commence all over again.

Referring again to FIG. 1 it is seen that a pair of

second control nozzles

24 and 28 are provided in bistable fluid amplifier 10 for setting and resetting the binary counter in the present invention. For the purposes of the present description, it is assumed that is represented when the fluid passes through passage 70 and "l" is represented when the fluid stream passes through passage 66 to utilization device 68. When it is desired to reset the counter to "0" signal is provided from a suitable source, not shown, through reset control nozzle 28 of fluid amplifier 10. This will cause the power stream emitted from the inlet nozzle 16 to either remain passing through outlet passage 18 or be flipped over to outlet passage 18 from outlet passage 20 if it happens to be flowing'in outlet passage 20. On the other hand, when it is desired to preset the binary counter, a fluid set signal is provided from a suitable course, not shown, through set control nozzle 24. This procedure will cause the power stream emitted from inlet nozzle 16 to either continue flowing through outlet passage 20 or be flipped over from outlet passage 18 to outlet passage 20 if the stream originally flowing in outlet passage 18. In this manner, the utilization device will sense a signal representing l It should be noted that fluid pulse device 44 must provide a pulse of duration which is less than the total of the switching time of bistable fluid amplifier and feedback time through

passages

62 and 64 to prevent oscillation of the counter.

Another embodiment of the present invention is illustrated in H6. 2 wherein the exclusive gates of FIG. 1 are replaced by AND

gates

72 and 74. AND gate 72 has an inlet nozzle 76, a pair of

outlet passages

78 and 80, and a control nozzle 82. The power stream provided by a suitable source 83 is emitted through inlet nozzle 76 and ordinarily will flow in outlet passage 80. Control nozzle 82 is connected to two sources of signals and the device is designed such that a signal form both sources must be present in order to deflect the power stream from outlet passage 80 to AND outlet passage 78. Outlet passage 80 is vented while outlet passage 78 is connected to control nozzle 22 of bistable fluid amplifier 10. One control signal flow is provided by means of feedback passage 84 connected intermediate outlet passage 18 of bistable fluid amplifier 10 and control nozzle 82 of AND gate 72. The other source of control signal flow is provided by means of fluid pulse device 44 through passages 86.

Similarly, AND gate 74 has an inlet nozzle 88, a pair of

outlet passages

90 and 92 and a control nozzle 94. Outlet passage 92 of AND gate 74 is vented while AND outlet passage 90 is connected to control nozzle 26 of bistable fluid amplifier 10. Control nozzle 94 of AND gate 74 is connected to both outlet passage of bistable fluid amplifier 10 through feedback passage 96 and the outlet of fluid device 44 by means of passage 86. inlet nozzle 88 is connected to a suitable source 97 of fluid.

The operation of this embodiment of the binary counter of the present invention is as follows. For the purposes of this description it is assumed that initially the power stream emitted from inlet nozzle 16 will pass through outlet passage 18. Accordingly, a portion of this power stream will be bypassed by means of feedback passage 84 and be emitted through control nozzle 82 of AND gate 72. An AND gate is designed such that the power stream emitted from inlet nozzle 76 will be emitted through outlet passage 80 unless a signal is received at control nozzle 82 from two sources whereupon the power steam will be deflected to AND outlet passage 78. Ac cordingly, when a fluid pulse is provided by means of fluid pulse device 44 it is transmitted through passages 86 to control

nozzles

82 and 94 if AND

gate

72 and 74 respectively. Since AND gate 74 requires a signal from fluid pulse device 44 and a feedback signal from outlet passage 20 of bistable fluid amplifier 10 before its power stream is deflated from outlet passage 92 to AND outlet passage 90, it will be unaffected by the portion of the fluid pulse provided by device 44 alone. On the other hand, when-the portion of the fluid signal from device 44 is passed through control nozzle 82 of AND gate 72 it combines with the feedback pulse passed through passage 84 and causes the power stream of AND gate 72 to flop over from outlet passage 80 to AND outlet passage 78 whereupon it is transmitted through control nozzle 22 of bistable fluid amplifier 10. At this point, the power stream passing through outlet passage 18 of fluid amplifier 10 will flop over to outlet passage 20 whereupon a portion thereof will be fed back by means of feedback passage 96 to control nozzle 94 of AND gate 74. When the next pulse is provided by fluid pulse device 44, it will not affect the flow through AND gate 72 as heretofore described however, it will combine with the feedback signal passing through passage 96 and will be emitted through control nozzle 94 of AND gate 74 causing the power stream to flip over from outlet passage 92 to AND outlet passage 90. This signal will pass through control nozzle 26 of fluid amplifier l0 and cause the power stream to be deflected from inlet passage 20 to outlet passage 18. Utilization device 68 will sense these pulses as heretofore described providing a count thereof.

It is understood that only one stage of a fluid operated binary counter has been described herein and where higher counting levels are desired a plurality of interconnected stages will be required as known in the art.

One familiar with the art will readily understand that the final design parameters of specific fluid devices will at least be dependent upon the fluid density, temperature, and pressure as well as the characteristics of the outlet stream at the point of utilization.

Although the present invention has been described with respect to specific details of certain embodiment thereof, it is not intended that such details be limitations upon the scope of the invention.
