<p>1,081,958. Pure fluid amplifier. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan.4, 1965 [Jan. 7, 1964], No.51755/64. Heading G3H. [Also in Division G4] A fluid pulsed-jet device comprises a pulsed power jet 1 leading to an interaction chamber 4 which receives control signals from inlets 5 or 6. The control signals are supplied as a low pressure steady flow and a signal from inlet 5 will form a clockwise vortex in the chamber 4 so that the pulsed jet issuing from nozzle 1 flows to the outlet 14, 7 and locks on to the wall 2. The control signal from inlet 6 has the reverse effect to direct the jet to the outlet 3, 8. However, if the control signal is changed from inlet 5 to 6 while the pulsed jet is flowing, this prevents the forming of the anti-clockwise vortex until the pressure pulse ceases and the vent pulse is then directed to outlet 3. Passages 9a, 9b are provided to equalise static pressures. In a modification, the device is asymmetrical and only one control signal passage is then necessary. Such a device may be used in a binary counter or shift register (see Division G4).</p> |
