  • coffers of varied shapes such as for example: triangular or rectangular truncated prism of coffers with helical 8 lateral surfaces: when leaving a space between two adjacent coffers square channels 14 or round channels 15 which are formed parallel or narrow down toward the disc periphery.
  • Vanes 16a may be positioned in the entry collector.
  • the coffers may be formed solid and sealed against entry of the material to be treated, or hollow and sealed. In the latter case they form a buoy lifting the propeller even to the extent that propellers of appropriate dimensions may develop a lifting force capable of even supporting the propeller operating means.
  • FIG. 8 illustrates two propellers, separately fixed on the same shaft to which they are attached by a muff 17 which may serve as additional buoy.

Both these means represent a second motor axis for creating acceleration of the material in the conduits, by injection of compressed air, vapor or gas, or the mechanical action of a screw.
  • the design embodiments of the propellers defined hereinabove effecting radial ejection may also be constructed to procure axialejection.
  • shaft 10 is connected at least to a cylinder 2a which has the same function as the plates 2, FIG. 7.
  • coffers 4, 5 are fixed to the revolution surface of each cylinder hollow or solid, sealed or not, to form axial conduits similar to the radial conduits of the embodiments described above.
  • the coffers have similar shapes as those described heretofore: they may be rectangular as at 4, or helical as at 5, etc.
  • a second cylinder 3a which has the same function as plate 3, FIG. 7, is positioned with its inner surface on the coffers to form the axial conduits, closed except at their extremities.
  • Several concentric rows of conduits may be assembled on a single propeller.
  • the second cylinder may project to a higher level than the first cylinder to form the inlet collector.
  • this embodiment may be executed by taking as a starting point FIG. 5 and imagining that the two plates with their conduits are lowered so as to position them, no longer perpendicularly to the axis of shaft 10, but at an other angle and, for example, parallel to this shaft.
  • this embodiment effecting axial ejection of the material may be combined with one of the radial ejection embodiments, as illustrated in FIGS. 17 and 18, to jointly effect radial and axial ejection.
  • the plates may have a shape other than circular, for example rectangular, as illustrated at FIG. 15. These rectangular plates may be positioned to procure special effects, e.g., rotate in the same or in opposite directions.
  • the ejection conduits may be provided at their outlet with a deflector, (not shown), which deviates the ejected material in a direction other than the axis of the ejection conduits.
  • the radial ejection propeller Rotated in a material to be treated, the radial ejection propeller, with smooth surfaces, glides in the material, producing therein a minimum of friction and, therefore, requiring a minimum of motor power, particularly when starting.
  • the material to be treated is ejected by centrifugal force out of the peripheral conduit extremities: new quantities of material are thereupon sucked into the collector center and repelled toward the conduits in which they are subjected to an acceleration which is a function of the rotation speed, the angle formed by the conduits with their tangent to the propeller edge and their length.
  • Said liquid streaks start from the shaft center and are thus accelerated while sheltered from the ambiant media, but in the very midst of the latter, without being subjected to the disturbing swirls of the ambiant media capable of creating frictions which might disturb acceleration, and thus provide a high acceleration with a small motor power.
  • a given propeller rotating at a given speed, provided with a given number of conduits, is adjustable to a certain extent, in ejected volume and power absorbed by regulation of the number and size of the conduits.
  • the space or the inner volume of all conduits of one single row occupy a space or inner volume less than 33 percent of the space or volume generated by two planes essentially perpendicular to the motor shaft and positioned directly above and under said row of conduits, excluding the space or volume generated by the cylinder while the cylinder occupies a space or volume approximately equal to the space or volume of the said row of conduits.
  • the inner volume of one single row of conduits is 7,5 percent approximately in relation to the volume occupied by the two planes essentially perpendicular to the motor shaft and positioned directly above and under said row of conduits.
  • the apparatus When it is required to treat less fluid products, which are more viscous or pasty, the apparatus should be conditioned to operate with ratios close to the volumetric values indicated above while the propeller to container diameter ratio should be close to 1.5 or 1.2 at maximum while the rotation speed should be increased above 750 R.P.M. In this case the aforementioned ratio should be diminished in proportion to the increase of the rotation speed.
  • the propeller When rotating, the propeller provided with several plates, as, for example, in FIG. 10, sucks the material from the bottom, ejects it radially against ambient material present at the extremities of the conduits, and if desired projects the latter material with ejected material against the container wall. If the level of material to be treated is at the height of the upper disk, without adding or subtracting material, the latter circulates, tracing a circuit, somewhat ovoidal with multiple spirals, somewhat similar to the windings of electric motors.
  • every other disk operates similarly. However, as soon as the material ejected by the first disk travels downwards, for example, from a deflector down to the level of the second upper disk, the latter ejects neutral material against the primary material to form a mix designated as secondary. From this the downward movement of already ejected and mixed material, facing the peripheral edge of the disks, leads to production of more and more complex mixes.
  • each of the latter shall eject no more neutral material but material which has already been subjected to a number n of mixes, n representing the number of disks.
  • Said stator may for example be constituted by milling bodies, sand or glass beads etc added to the material to be treated and in which it forms a mobile or semi-fixed stator which acts similarly to a fixed stator.
  • FIG. 10 illustrates a sectional view on a single plane of a double oval trajectory of an idle machine.
  • said double oval trajectory is formed of two single ovals connected through one of their branches.
  • Each oval comprises two vertical branches of which one is located at the entry and the other at the outlet of the conduits which insure acceler- 311011.
  • the created trajectories may be illustrated as the wires of an electric motor wiring system.
  • the described apparatus execute a real treatment process such as heretofore, defined which may be executed by combining the aforementioned means in apparatus different from those already described and illustrated.
  • Apparatus for propelling fluids comprising:
  • a rotatable propeller disposed within a container
  • 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;
  • conduits associated with said holes, said conduits being aligned in at least one row and being rotatable with said motor shaft;
  • the inner volume of said entry collector being approximately equal to the cumulative inner volumes of said conduits of said one row.
  • Apparatus according to claim 1 including two entry collectors, opened at the top and the bottom respectively, each collector comprising at least one row of conduits.
  • conduits are in the shape of pipes.
  • each conduit has an inlet section and an outlet section, said inlet section differing from said outlet section.
  • Apparatus according to claim 1 including, in one container, a plurality of propellers.
  • Apparatus according to claim 1 including an injection nozzle to supply high speed fluid at the collector entry for applying motor power to the system.
