Abstract
Abstract Apparatus for propelling any type of liquids which comprises in a container at least one motor shaft and one essentially central entry constituted by at least one entry collector having the shape of a hollow cylinder including one opening at one side and a bottom essentially closed on the other side, and holes disposed in at least one row concentric to the motor shaft in which are fixed a plurality of conduits preferably individual and closed, except at their extremities. The space or inner volume of one whole single row of conduits occupies a space or volume inferior to 33% of the space or volume comprised between two surfaces located tangentially to and fro of the conduits of the aforesaid row of conduits, and delimited by the peripheral extremities of the latter, excluding the space or volume of said hollow cylinder comprised between two aforesaid surfaces, and wherein said cylinder occupies a space or volume approximately equal to the space or volume of the row of conduits.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
212 words
Apparatus for propelling fluids comprising: a. a rotatable propeller disposed within a container; b. at least one rotatable motor shaft connected with said propeller; c. said propeller including at least one entry collector, said entry collector being in the form of a hollow cylinder which is open at one end and closed at the other end, said cylinder being concentrically disposed with respect to said motor shaft; d. a plurality of holes in said hollow cylinder, said holes being aligned in at least one row; e. a plurality of conduits associated with said holes, said conduits being aligned in at least one row and beiNg rotatable with said motor shaft; f. a top plate and a bottom plate, said plates being disposed, respectively, above and below said row of conduits and being tangential thereto; g. said plates extending from said entry collector to the outermost extremeties of said conduits; h. said entry collector, outermost conduit extremities and top and bottom plates defining a sealed-off area; i. the cumulative inner volumes of said conduits of one row being less than 33 percent of the volume of said sealed-off area, and; j. the inner volume of said entry collector being approximately equal to the cumulative inner volumes of said conduits of said one row.
Claim 2
Dependent Claim
