(Cl. 171-97) protective grid about the cathode directly, or This invention relates to a method and means for generating and utilizing extremely high volt ages at high energy levels“ 4 This is a division of my copending application 5 Serial No.‘684,328, ?led August 9, 1933. This divisional application is speci?cally directed to a high-voltage generating system wherein charging devices are arranged in parallel,‘ and means be ing provided to discharge said devices in series. 10 In one way of carrying out my invention for the generation of high D. C. voltages, I charge metal lic'units, preferably particles of metal, by actual conductive contact with a D. C. source. Then, by moving the particles away from‘the source, 15 the voltages of the charges thereon are increased, in a manner which shall be eirplained more fully hereinafter, and the charges are ultimately de posited upon a low voltage gradient-section of a charge-storing device or container.) , 20' In another arrangement for producing high voltages vaccording to my present invention, an induction electrode, either grounded, or prefer ably maintained at a high voltage, is insulatingly separated froni- a chargeable medium which may 25 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 mediuin. through a bias source, to the cathode. Still further objects of my present invention are to provide an improved belt system for gen erating high voltages; to provide an improved 5 disk system for generating high voltages; to pro vide improved combinations of disks alone or ' combinations of disk or disks and belt or belts alone, arranged in such a way ‘as to have an eifective output voltage much higher than the 10 voltage generated by any one system; and to pro vide a symmetrical network system in which var ious elements are charged in parallel but dis charged in series so as-to obtain a much higher resultant output voltage as compared to the 'volt- 15 age applied to each element. This invention will be more fully understood by referring to the accompanying drawing, in . which . Fig. 1 illustrates a symmetrical system for charging condensers in parallel and discharging them in series, in order to obtain a high resultant output voltage; ‘ Fig. 2 is another modi?cation of Fig. 1; Fig. 3 illustrates a recti?er for rectifying and storing the pulsating voltages and energies de veloped in the apparatus illustrated in Fig. 2. Referring now to Fig. 1. the arrangement of this system shows a high-voltage source 400,, which may, for example, be any one of the sources or Thev charged medium is then moved or carried to combination of systems described in Figs. 1 to 10 a low gradient area on a chargeable element, the of my copending application Serial No. 684,328, ' ‘high voltage surface of which is brought up to an 1 ?led Aug. 9, 1933'. The high voltage source 400 exceedingly high voltage by the continued‘ de posits from the charged medium. . charges, through resistor 402, a balanced spark gap system. This spark 'gap system comprises 35 ' Other modi?cations of‘ my invention are that of spark gaps 404, 406, 4'08 symmetrically intercon the contact and induction principles for charg ing solid mediums such as belts and disks, for charging liquids such-as oil and 011 containing nected by resistoror reactors and condensers 4 I 0, ll 2, respectively. The source 400, which is either a high voltage A. C. of relatively low frequency, or metallic particlesin suspension and for charging , D. C. source, charges the condensers “2 through 40 gases. » ~ My ‘invention further contemplates, in connec tion with a cascaded transformer system, the recti?cation of the voltage of each stage. As it is desirable to make'the voltage of each stage as high as possible, it ‘will be found that ordinary tube recti?ers subjected to high A. C. voltages for ‘ recti?cation, will have their ?laments subjected to high electrostatic streses leading to their rapid destruction. Consequently, a further object of my present‘ invention is to provide an improved‘tube recti?er circuit. For this purpose I provide an arrangement wherein the cathodes or filaments are protected from subjection to high electrostatic forces by suitably connecting a resistors 402, llll in parallel. However, when dis charge of the spark gaps I“, 406, "8 occurs, the discharge, as well known to those skilled in the art, is of extremely rapid character and acts se rially through the condensers ‘i2, disregarding 4.5 resistors llli as too slow means for discharge, thus producing momentarily across the spheres 4“ an integrated voltage. That is to say, the charging takes place in parallel, whereas the discharge, taking'place in series, gives a much 50 greater effective output voltage. . - An arrangement somewhat similar to that shown ‘in Fig. 1, but somewhat _more re?ned, is illustrated in Fig. 2. as in connection with Fig. 1, the source “ll may be any one‘of the devices, I6 2,1 rates combination of devices or systems illustrated in ' Figs. 1 to 5 of my copending application Ser.
