Abstract: A highly efficient water purification device includes a degasification apparatus, a distillation apparatus and an ion removal device to purify contaminated water. When a partial vacuum is applied to the degasification apparatus, dissolved gases leave the water, and a heat exchange process occurs which heats the gases and cools the degassed water. A gas exhaust channel transfers the warmed gases to a heating coil in the distillation apparatus to preheat water for evaporation therein while the cooled, degassed water is transferred to a condenser to condense vapor and steam. The degasification apparatus may include one or more towers in which a vacuum is formed by first filling the towers with water, sealing the tower top, and then draining water from the tower bottom; this vacuum may be applied to the distillation apparatus and a reservoir by transferring the vacuum from the towers through a depressurization conduit to thereby achieve boiling in the distillation apparatus at reduced temperatures.

Abstract: A device for removing dissolved gases from liquids is provided by utilizing a tall column initially filled with liquid which is then opened at the bottom allowing the liquid level to drop forming a vacuum above the liquid level. Dissolved gases migrate to the vacuum area and the purified liquid is then drained from the bottom of the column and the process repeated.

Abstract: An energy conserving electrical apparatus for driving a load and recovering otherwise wasted electrical energy utilizes an electric motor with field windings on one or more pole members and one or more rotors. During a first time interval whose duration is determined by motor speed, electric current is supplied to the field windings from a first charged battery, the current flowing through electrical switching circuitry to the field windings of the motor to thereby turn the rotor by establishing a magnetic field, as is well known in the motor art. During a second time interval, the duration of which is also determined by motor speed, the rotor's poles confront the poles of the field winding and the switching circuitry disconnects the first battery from the field windings and connects a second discharged battery to the field windings for charging of the second battery.
