Patented Jan. 19, 1943 HIGH VOLTAGE GENERATOR Nils E. Lindenbiad, Rocky Point, N. Y., casino: to Radio Corporation of America, a corporation of Delaware Original application August 9, 1933, Serial No. 684,328. Divided and this application January 23, 1940, Serial 170.815.1879

3 Claims. (Cl. 171-329) My present invention has as its main object the provision of methods and means for generating very high potentials or voltages at high energy levels.

In one way of carrying out my invention for the generation of high direct current voltages, I charge metallic units, preferably particles of metal, by actual conductive contact with a direct current source. Then, by moving the particles away from the source, the voltages of the charges thereon are increased, in a manner which will be explained more fully hereinafter, and the charges are ultimately deposited upon a low voltage gradient-section of a charge-storing device or container.

This application is one of several divisions of my original patent application, Serial No. 684,328, filed August 9, 1933, which has now matured into Patent #2,210,492, dated August 6, 1940, which contains, but does not claim, the identical disclosure of .the instant application. The parent patent application contains claims directed-to the belt system and also the combined belt and disc system. A first divisional application, Serial No. 4,475, filed February 1, 1935, which has matured into Patent 2,070,972, dated February 16, 1937, contains claims directed to the rotor system wherein an inductive principle is combined with centrifugal force and utilized to increase the output voltage. A second divisional application, Serial No. 8,236, filed February 26, 1935, which has now matured into Patent 2,119,588, dated June7,1938, contains claims directed to the high voltage generating system wherein charging units are arranged in parallel with means provided to discharge them in series. A third divisional application, Serial No. 81,360, filed May 23, 1936, which has matured into Patent 2,171,242, dated August 29, 1939, contains claim directed to a high voltage generator com-' applied to gases.

In another arrangement for producing high voltages according to my present invention, an induction electrode, either grounded or prefer- R ably maintained at a high voltage, is insulatingly separated from a chargeable medium which may be a solid, a liquid, or a gas, and, by the use of a point discharge electrode system connected to a direct current source or preferably to ground, ionization or corona is caused to .take place through and/or about the chargeable medium.

The charged medium is then moved or carried A further and more specific object of my" present invention is'to provide systems which utilize my improved contact and induction principles.

This description will be given in greater detail with the aid of the accompanying drawing which, however, is not to be considered in any way llmitative of my present invention but is to be considered only illustrative. Referring now in detail .to the drawing:

Fig. 1 is a sectional view wherein the high potential voltages are applied to gases;

Fig. 2 is another method of charging a metallic container to a high voltage by the use of gases.

As an example of the manner in which my improved induction system for generating high voltages may be applied to gases, particular reference is made to Fig. 1. By virtue of a motor 508 driving a pump 510, oil is sprayed through nozzle 5i2 vertically through glass pipe or insulating cylindrical chamber 5l4. Air sucked in or pumped in through ball valve Sit and orifices 5l8 forms bubbles with the oil. Instead of air, other gases such as helium, nitrogen or mixtures thereof may be used. By applying a high voltage to the electrode 520 through conductor 522 from a suitable source (not shown) corona discharge will take place at the metallic points 524 mounted on a metallic grounded electrode 526. As a consequence, the air in the oil bubbles becomes ionized, passes upwardly into the metallic elbow 528 and through metallic wire screen 530. Consequently, the charges are fed on to the metallic false bottom 532 to the interior zero gradient surface of the sphere 534, whose outer surface rapidly becomes charged to an exceedingly high potential. Excess oil may be carried ofl through glass pipe 536 to be repumped through pump M0.

The system shown in Fig. 1 may be applied to advantage in internal combustion engines. In that case, the air supply would be completely shut off but the gasoline sprayed past the corona points 524 would charge up the particles of gasoline. The gasoline could then be fed into the combustion portion of the engine with air and the resultant explosions should give relatively greater power and more complete combustion than that now available in the ordinary type of gasoline engine, due to the beneficial action of the ionization.

Another way of charging a metallic container to a high voltage by the use of gas is illustrated in Fig. 2. Air is blown through a pipe 550 past a plurality of discharge points 552 whose terminals, as illustrated, are connected to ground and to the high voltage side, of for example, an induction coil. I'he ionized air is then blown through a metallic screen 554 which may be maintained at a positive or negative potential, depending upon the character of ions desired. The screen 554 will remov ions of opposite polarity as a result of which ions blown through glass tube 556 impinge upon the shell 558 and lose their charge to charge up condenser or storage device 558 to a plurality opposite that of screen 554.

The ions emanating from glass tube 556 need not, however, be used for charging purposes but may be inhaled for medical treatment, that is to say, used therapeutically. If desired, a series of screens 554 may be arranged at the same polarity but of different values or at the same values of potential so as to insure obtaining ions of merely one polarity. For medical purposes, ions of either polarity may be used to the exclusion of others depe ding upon which type is found more helpful.

Various changes will readily suggest themselves in carrying out the principles of my present in vention. Accordingly, my present invention is not to be considered limited by the various illustrations given but on the other hand is to be given the full scope indicated in the appended claims.

l. A high voltage generating system comprising an insulating cylinder, a fluid inlet at one end of said cylinder and a fluid outlet at the other end thereof, a first electrode maintained at ground potential and located within said cylinder, a second electrode maintained at high voltage and located outside said cylinder and in the same zone as said first electrode, a metallic member located at the fluid outlet of said cylinder, and means for passing fluid through said insulating cylinder whereby the charge carried by said fluid increases in voltage as it reaches said metallic member.
