1. A remote, completely self-contained, self-maintaining power supply apparatus for powering a pressurized-liquid distributing, and disseminating system, comprising:

  • a pressurized-liquid distriburing and disseminating system portion including at least a portion of a main pipe means provided with a pressurized liquid flowing therethrough and provided with at least one power utilization device, and controlling servo motor means, connected thereto and adapted to have a controlled amount of said pressurized liquid fed therethrough;

    electrical energy supply means including electrical generating means and electrical energy storage means and first energy-storing coupling means taking the form of an electric circuit means interconnecting said electrical generating means and said electrical energy storage means in an energy-storing manner, said electrical generating means being provided with fluid motor means coupled thereto and in driving relationship thereto and being positioned within the path of flow of at least a portion of said pressurized liquid flowing through said main pipe means and responsive to such flow for periodically producing electrical energy during periods when said pressurized liquid flows relative to said electrical generating means and for storing, by ways of said electric circuit means, said electrical energy in said electrical energy storage means during said periods, said electrical energy storage means being provided with second coupling means comprising electric circuit means controllably effectively connected in an energy-releasing manner with respect to said servo motor means coupled with Repect to said power utilization device associated with said main pipe means in a particular desired manner for modifying the flow of said liquid through said power utilization device;

    said first coupling means including coupling switch means provided with and controlled by activation means for causing said effective coupling of said first coupling means in said energy-storing manner with respect to said electrical energy storage means only when said electrical energy storage means has stored therein less than a predetermined magnitude of electrical energy, as indicated by the output voltage thereof, and including generator output modifying means, for modifying and controlling the output of said electrical generating means, effectively coupled with respect to said electrical generating means during said periods of flow of said perssurized liquid through at least a portion of said main pipe means and relative to said fluid motor means driving said electrical generating means, in a manner modifying the electrical output thereof as a direct function of, and in response to, the deficiency of said electrical energy stored in said electrical energy storage means, said generator output modifying means comprising an input portion effectively coupled with respect to said electrical energy storage means and an output portion effectively coupled with respect to said electrical generating means in a manner correspondingly modifying both the mechanical output of said fluid motor means and the electrical output of said electrical generating means, said output portion comprising a reversible servo motor means and generator output changing means coupled to said servo motor means, with said servo motor means being effectively electrically energized by said output error electrical signal produced by said input portion, said servo motor means effectively controlling input to the electrical generating means in inversely proportionate response to the charge output of said electrical energy storage means.
