    摘要: In the invention, an electrochemical cell including an oxygen reducing cathode, an oxygen generating anode and an electrolyte, and having both a deoxygenating function and an oxygen generating function is coupled to a chamber in such a manner that, when the oxygen concentration in the chamber is much higher than a predetermined value, the deoxygenating function is utilized to decrease the oxygen concentration and when the oxygen concentration in the chamber is much lower than the predetermined value, the oxygen generating function is utilized to increase the oxygen concentration so that the oxygen concentration in the chamber is maintained at the predetermined value.

    摘要: In accordance with the present invention, a microfluidic device and method of using the same is provided for self-regulating the flow of fluid therethrough. The microfluidic device includes a body defining first and second flow channels. The first flow channel has an input for receiving the fluid and an output. The second flow channel has an input for receiving a compensating fluid to modify the value of the property of the fluid and an output communicating with the first flow channel. A polymeric material is disposed in the first flow channel downstream of the output of the second flow channel. The polymeric material has a volume responsive to the value of the property of the fluid. A valve is disposed in the second flow channel and is movable in response to the volume of the material. The valve is movable between the first open position allowing the compensating fluid to flow past the valve into the first flow channel and a second closed position limiting the flow of compensating fluid therepast.

    摘要: An automatic feeder for infusing solid solutes into liquid solvents at an adjustable, predetermined, controlled rate to maintain an adjustable, predetermined, controlled concentration of solute in a solvent reservoir, the feeder including means for adjustably controlling the rate of infusion of solute into a circulating, solvent stream within a chamber by controlling the quantity of solvent in the chamber as well as surface area of solute immersed in the solvent, means for feeding solute into the solvent in the chamber in a programmed fashion over a relatively long period of time without attendance, means for preventing accidental syphoning of all of the solvent from the feeder, and means for automatically breaking contact between the solute and the solvent in the feeder during periods of dissolution; the feeder comprising a housing having solvent inlet and outlet ports, a float valve for adjustably controlling the level of solvent circulating in the housing; and an anti-syphoning device on the float valve to prevent total discharge of solvent from the feeder and a solid, solute supply canister mounted on the housing extending into the solvent therein, the canister having a narrowed neck at the bottom to release tablets of solid solute after a predetermined degree of dissolution.

    摘要: The invention relates to a method for controlling the water supply of a water-injected compressor, into the cooling water circuit of which is injected demineralized and non-demineralized water as fresh water. The method according to the invention is characterized in that the fresh water supplied is a mixture of demineralized and non-demineralized water, and the proportions of the demineralized and non-demineralized water in the fresh water are dependent on the conductivity of the demineralized and non-demineralized water. The invention also relates to a water-injected gas compressor that may be operated with such a method.
