Abstract

995, 828. Controlling fluid flow. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 21,1964 [May 28,1963], No. 20950/64. Heading G3H. [Also in Division G4] In a fluid amplifier a pressure pulse to one side of a laminar fluid stream discharging into a main outlet channel renders it turbulent and causes it to adhere to a wall and discharge into an auxiliary channel only while said pressure pulse is applied. In Fig. 1, fluid from a pipe 14 is rendered laminar by ribs 16 and a channel 17, then discharged to an outlet pipe 30 through a channel 29 unless a fluid pressure pulse is applied through one of two control ports 23, 24 in which case the outer layer (only) of the fluid stream becomes turbulent and it adheres to wall 20 or 19 respectively while the pulse lasts, and discharges into pipe 28 or 26 through channel 27 or 25 respectively. If a pulse is applied to both control ports 23, 24 the stream discharges to the central pipe 30. Escape ports 31, 32 are provided to bleed off excess pressure to prevent it separating the jet from a wall to which it is adhering. If the output is taken from pipes 26 and 28 the amplifier functions as an EXCLUSIVE OR gate. Fig. 4-7 (not shown) show a modification of the Fig. 1 arrangement comprising in addition another control channel inclined at 45 degrees to both channels 17, 22 and meeting the junction thereof. The extra control channel is fed by a Helmholtz resonator cavity actuated by an earphone operating, say, in the range 1. 5-3. 0 kc/s. Alternatively even more control channels may be OR'd together on one side to produce a pressure signal sufficient to render the outer layer of the fluid stream turbulent if any one or any certain number of the control channels are pulsed.
