  • Fluidically-controlled air-conditioning system
    Patent number: 4211363
    Abstract: The present invention is one that uses the novel feature of fluidics to control the flow of conditioned air in an air-conditioning system. More specifically, in one species of the invention, fluidic amplifier apparatus controls the flow of hot water into the coils and, therefore, controls the changeover from cool to warm air in the main duct, and in a second species it not only controls the mentioned changeover but also the volume of the conditioned air flowing in the duct.

  • Fluidic-amplifier device having tube in outlet channel
    Patent number: 4181153
    Abstract: The present invention involves the insertion and use of a tube in one of the outlet channels of a pure fluid bistable amplifier. The amplifier will function so long as the cross-sectional area of the tube is less than twenty percent (20%) of the cross-sectional area of the outlet in which it is mounted. The advantage of the tube is that velocity-pressure recovery can be as high as eighty percent (80%) as compared to forty eight percent (48%) without it.
