Abstract
Abstract A pair of opposed spaced electrodes and dielectric medium between the electrodes, and means for changing the dielectric constant of the dielectric medium so as to vary the electrical capacitance of the electrodes with the changing of the dielectric constant. The electrodes are charged when the dielectric constant of the dielectric medium is high and discharged when the dielectric constant of the dielectric medium is low. The discharge voltage is increased by a factor proportional to the ratio of the capacitance during charging and the capacitance during discharging.

Claim 1
Independent Claim
149 words
In a device for increasing the voltage of a direct current voltage source, a set of spaced electrodes of constant effective surface area, said electrodes having alternative positive and negative polarities, a first dielectric medium of a single predetermined constant between said set of electrodes, a second dielectric medium of lower dielectric constant than that of said first dielectric medium being capable of combining with said first dielectric medium so that the combined dielectric media have a lower dielectric constant than that of said first dielectric medium, means to impart a charge of direct current electricity to said electrodes when said first dielectric medium is the only medium between said electrodes, and means to discharge said pair of electrodes when said dielectric media are combined, and means intermittently to combine said dielectric media for alternately lowering and increasing the dielectric constant between said electrodes respectively during discharging and charging.

Claim 3
Dependent Claim
102 words
The invention defined in claim 1 and a dielectric having a dielectric constant lower than said predetermined dielectric constant, means to introduce the dielectric of lower dielectric constant intermittently between said spaced set of electrodes and said dielectric medium of predetermined dielectric constant while said dielectric medium remains between said electrodes, said charging means to charge said pair of electrodes with direct current voltage from said direct current voltage source when said dielectric medium of predetermined dielectric constant is between said pair of electrodes, and said discharge means operating when said dielectric of lower dielectric constant is between said pair of electrodes.
Claim 4
Dependent Claim
67 words
The invention defined in claim 1, and said first dielectric medium including, separable sections of dielectrics having high dielectric constants movable apart by the respective electrodes, and said secoNd dielectric medium being of low dielectric constant and being capable of occupying the space between the sections when they are moved apart, thereby to lower the overall dielectric constant of the combined dielectrics between said pair of electrodes.
Claim 5
Dependent Claim
109 words
The invention defined in claim 1, and one of said electrodes being movable away from said first dielectric medium thereby to create a space between said movable electrode and said first dielectric medium and admitting said second dielectric medium of low dielectric constant in the space between the movable electrode and the first dielectric medium and thereby to lower the overall dielectric constant of the combined dielectrics between the pair of electrodes, means to connect said movable electrode to said charging means in its initial position, and means to connect said movable electrode to said discharging means when the electrode is spaced from said dielectric of high dielectric constant.
Claim 6
Dependent Claim
63 words
The invention defined in claim 1, and said first dielectric medium being capable of having its thickness decreased to be spaced from one of the electrodes for admitting said second dielectric medium thereby to lower the overall dielectric constant between said electrodes, and means alternately to decrease and increase the thickness of said dielectric medium between said electrodes respectively during discharging and charging.
Claim 7
Dependent Claim
89 words
The invention defined in claim 1, and said first dielectric medium being a liquid dielectric in an insulating container, said electrodes being formed by spaced conductor sides of said container, and means to alternately withdraw liquid from said container and refill said container for alternately creating a space between one of said electrodes and said liquid respectively admitting said second dielectric medium for decreasing the dielectric constant between said electrodes during said discharging and expelling said second dielectric medium for increasing the dielectric constant between said electrodes during charging.
