Abstract
Abstract A container for containing a first fluid having conduit means leading from and to said container in a loop with the container together with a pump interposed in the conduit means for moving a fluid through the container means and the conduit means and means for creating an increase in the fluid velocity of the fluid moved through the conduit means with a resultant lower pressure area thereby creating an inducement area followed by an area of high turbulence further including means for subjecting a second fluid to the inducement area to introduce the second fluid into the first fluid and subject the mixture to the area of high turbulence.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
300 words
A device for mixing one fluid with another fluid in a manner to prevent the introduction of air into the mixture, comprising: a. a first tank for containing the first fluid; b. an impeller pump having an input for accepting fluid to be pumped and an output for providing fluid under pressure; c. a first conduit having a first end connected to the bottom of the first tank and a second end connected to the input to the impeller pump; d. a second conduit having a first end connected to the output of the impeller pump and a second end connected to the first tank; e. a second tank for containing a second fluid to be mixed with the first fluid outside the first tank without the introduction of air into the mixture; f. valve means connected to the second tank to control the flow of fluid out of the second tank; and g. a third conduit having a first end connected to the valve means and having a second end connected to the first conduit in a manner that the second end of the third conduit is immersed in any stream of fluid flowing in the first conduit to allow the mixing of the first fluid and the second fluid outside of the first and second tanks, and without the introduction of air into the mixture, at a position before the first fluid flowing from the first tank reaches the input to the impeller pump, the suction of the impeller pump drawing as much of the second fluid as the valve means will permit, and the turbulent condition within the impeller pump dispersing the second liquid into microdroplets with an increased surface area such that the second liquid is rapidly mixed with the first liquid within the impeller pump.

A device for mixing one fluid with another fluid in a manner to prevent the introduction of air into the mixture, comprising: a. a first tank for containing the first fluid; b. an impeller pump having an input for accepting fluid to be pumped and an output for providing fluid under pressure; c. a first conduit having a first end connected to the bottom of the first tank and a second end connected to the input to the impeller pump; d. a second conduit having a first end connected to the output of the impeller pump and a second end connected to the first tank; e. a second tank for containing a second fluid to be mixed with the first fluid outside the first tank without the introduction of air into the mixture; f. valve means connected to the second tank to control the flow of fluid out of the second tank; and g. a third conduit having a first end connected to the valve means and having a second end connected to the first conduit in a manner that the second end of the third conduit is immersed in any stream of fluid flowing in the first conduit to allow the mixing of the first fluid and the second fluid outside of the first and second tanks, and without the introduction of air into the mixture, at a position before the first fluid flowing from the first tank reaches the input to the impeller pump, the suction of the impeller pump drawing as much of the second fluid as the valve means will permit, and the turbulent condition within the impeller pump dispersing the second liquid into microdroplets with an increased surface area such that the second liquid is rapidly mixed with the first liquid within the impeller pump.
Claim 3
Dependent Claim
49 words
The device of claim 1, wherein the first conduit includes a union, and the second end of the third conduit connects with the union to allow a mixing of the first and second fluids outside of the first and second tanks without the introduction of air into the mixture.
