Abstract: A dispenser container for a paste is provided. The dispenser container is formed from a cylinder open at one end for holding the paste, a displaceable tightly fitted follower plate means is arranged at the open end of the cylinder and a dispenser for transporting the paste from the container is arranged to cooperate with the follower plate. A motor and transmission are mounted near the center of the follower plate and has a shaft which extends through the follower plate and has mounted thereon a multiple blade stirrer. The stirrer rotates in the paste below the follower plate. The dispenser removes the paste from the container at a position away from the center of the follower plate in an area below which the multiple blade stirrer rotates. The multiple blade stirrer by rotating in the paste lowers the viscosity and permits the paste to be more easily transported from the container by the dispenser.

Abstract: This invention is directed to an apparatus for dosing a solution into a liquid conduit by means of a piston dosing pump mechanically driven by the liquid pressure, which comprises a dosing pump having a chamber containing liquid from the conduit and into which the solution is delivered from a supply source, a spring-biased nonreturn valve between the dosing pump chamber and the liquid conduit, and a second pump which supplies fresh liquid to the dosing pump chamber, the piston of the second pump being synchronized with the piston of the dosing pump.
