Definitions

  • the present invention relates to pure fluid logic elements and, more particularly, to a twin and-gate for use in fluid logic systems.
  • the apparatus of the present invention is related to pure fluid systems of the general type described in US. Patent No. 3,024,805 issued to Billy M. Horton; Patent Nos. 3,001,698 and 3,016,066 issued to Raymond W. Warren and Patent Nos. 3,001,539 and 3,004,547 issued to Hyman Hurvitz.
  • twin and unit of the present invention is of general applicability in pure fluid digital systems but is described in terms of its application to a pure fluid counter or shift register.
  • Still another object of the present invention is to provide a twin and unit which may be employed in pure fluid shift registers.
  • FIGURE 1 of the accompanying drawing illustrates the pure fluid twin and unit of the present invention.
  • FIGURE 2 illustrates two fluid flip-flops interconnected by a twin and-unit to provide a shift register.
  • a pure fluid device formed as channels in a plate 1 wihch may be of plastic, glass, or other suitable material.
  • the top surface of the plate 1, as viewed in FIGURE 1 is adapted to be covered by a further plate which forms a fluid-tight seal between the further plate and the surfaces of the plate 1 which are not recessed. In this way, fluid supplied to the apparatus is confined to the fluid paths formed as channels in the plate.
  • the apparatus of FIGURE 1 comprises a first nozzle 2 employed as a trigger or timing pulse input to the apparatus.
  • the fluid is supplied to the nozzle 2 through an input aperture 3 adapted to have fluid supplied thereto at relatively precisely timed intervals.
  • Located to the left of the nozzle 2 as viewed in FIGURE 1 of the accompanying drawing. is a second nozzle 4 lying at a predetermined angle relative to the centerline of the "ice nozzle 2.
  • the nozzle 4 is supplied with fluid through an aperture 6 and, when fluid is supplied through the aperture 6, the nozzle 4 issues fluid which intercepts fluid issued by the nozzle 2 if such fluid is being issued at that time.
  • a third nozzle 7 Positioned to the right of the nozzle 2, as viewed in FIGURE 1, is a third nozzle 7 adapted to have fluid supplied thereto through a passage 8 in the plate 1.
  • the centerline of the nozzle 7 lies at approximately the same angle relative to the centerline of the nozzle 2 as the centerline of the nozzle 4.
  • the fluid issued by the nozzle 2 follows a path indicated by an arrow 9; fluid issued by the nozzle 4 follows a path indicated by an arrow 11; and fluid issued by the nozzle 7 follows a path indicated by the arrow 12.
  • the apparatus is provided, in effect, with five outlet passages.
  • a center passage 13 is positioned downstream and along the centerline of the nozzle 2 so that fluid issued by this latter nozzle, if not intercepted by any other fluid stream, flows directly to the outlet passage 13.
  • the passage 13 is employed as a fluid dump; that is, the fluid entering this passage may be vented directly to the atmosphere through a passage 14 formed in the plate or may be returned to the pump supplying fluid under pressure if the system is to be employed as a closed system.
  • a further outlet passage 16 is positioned at the right side of the apparatus as viewed in FIGURE 1 and is employed to collect undeflected fluid issued by the nozzle 4. Fluid flowing to the outlet passage 16 may flow through a passage 17 in the plate 1 to the ambient atmosphere or to the return side of the pump.
  • the passage 16 also serves to defeat boundary layer effects in that it removes sidewalls from the apparatus which might otherwise be present and which, if present, might influence the paths of flow of the various fluid streams in the apparatus.
  • a third outlet channel or passage 18 is formed at the left side of the apparatus as viewed in FIG URE 1 and is generally a mirror image about the center line of the nozzle 2 of the outlet passage or channel 16. The passage 18 is adapted to receive an undeflected stream issued by the nozzle 7 and also serves to prevent boundary layer effects at the left side of the device.
  • the apparatus is provided with two further outlet passages having rather narrow inlet openings. These passages constitute signal output channels and are designated by reference numerals 19 and 21, respectively.
  • the input orifices to the channels 19 and 21 are quite narrow so as to minimize the possibility of fluid entering these passages in the absence of fluid streams being directed precisely at their openings. This feature is not absolutely essential to the operation of the system but does impart a high degree of reliability to its operation.
  • the input orifices 6 and 8 would normally be connected to sense the condition of some prior stage or stages of a pure fluid system. This is not an essential mode of operation of the apparatus since signals applied to these nozzles may be derived from transducers but, for purposes of explanation, it will be assumed that they receive fluid from pure fluid devices.
  • the system is such that, if fluid is applied initially to the nozzle 4 at a time T, when fluid is supplied to the nozzle 2, the fluids issued by nozzles 2 and 4 interact and the stream formed by the confluence and interaction of these two streams follows a path indicated by an arrow 22.
  • This path is directed at the entrance to the right output passage 21 and thus, under these circumstances, fluid is supplied during the interval T to this passage.
  • fluid supplied to the nozzle 4 follows the path indicated by the arrow 11, passes through the channel 16 and is dumped. If a signal is not applied to the passage 4 at the time T then the stream issued by the nozzle 2 enters passage 13 and is dumped.
  • the elements comprising nozzles 2 and 4 and passages 13, 16 and 21 constitute a two-input and gate.
  • the orifices 6 and 8 are connected to two output channels 24 and 26, respectively of a single flip-flop 27.
  • the output channels 19 and 21 are connected to two control nozzles 28 and 29, respectively of a subsequent flip-flop 31. If fluid is supplied to the nozzle 4, this indicates that the flip-flop 27 of the prior stage of the register has fluid supplied to its left output channel 24.
  • fluid flows through the passage 21 to a right control nozzle 29 of the next stage of the register and causes the flip-flop to switch its flow, if it is not already so directed, to its left output channel 32 of that stage.
  • the condition established in the stage prior to the illustrated apparatus is passed along to the stage following the illustrated apparatus.
  • nozzles 4 and 7 may be employed as an inhibiting input to the system, further extending the utility of the device.
  • a pure fluid logic element having and gate characteristics comprising a first nozzle for issuing a first stream of fluid, a first outlet passage positioned downstream of said first nozzle and generally aligned with the centerline of said first nozzle, a second nozzle disposed on one side of said first nozzle and posiitoned to issue a second stream of fluid into intercepting relationship with said first stream of fluid, a second outlet passage positioned downstream of said second nozzle and generally aligned with the centerline of said second nozzle for receiving said second stream when undeflected, a first output passage positioned to receive a first composite stream of fluid resulting from confluence and interaction of said first and said second stream of fluid, a third nozzle disposed on the other side of said first nozzle and positioned to issue a third stream of fluid into intercepting relationship with said first stream of fluid, a third outlet passage positioned downstream of said third nozzle and disposed generally along the centerline of said third nozzle for receiving said third stream of fluid, and a second output passage positioned to receive a second composite stream of

  • said outlet means comprises a plurality of channels including a first channel positioned to receive said second stream of fluid when undeflected, a second channel positionedto receive said third stream of fluid when undeflected and a third channel positioned to receive said first stream of fluid when undeflected and a sixth stream of fluid formed by the confluence of said second and thirdstreams of fluid.
