e claims.
The present invention relates to high voltage generators.
One of the objects of the present invention is to provide a simple and highly efficient generator for the production of extremely high voltages.
Another object is to enable the generation of high voltages by the continuous accumulation oi successively acting electrostatic charges upon a vessel or an electrode.
In brief, the invention comprises an arrangement in which small streams of conducting or semi-conducting liquid are broken up into drops which are subjected to an intense electric field in a direction parallel to the motion of the liquid. Each drop of the liquid as it is formed .acquires a considerable amount of electric charge which, as soon as the drop separates from the main stream, is bound upon the drop and cannot escape from it. These drops with their electrostatic charges are caught in a vessel of conducting material and give up their respective charges as soon as'they come in contact with the vessel or the liquid within it. In this manner the vessel continuously acquires charges from the conducting liquid drops and builds up a very high potential. The vessel in its preferred form is insulated from ground in order to prevent leak- Iage or energy dissipation, and the charge on the vessel utilized by any suitable circuit requiring extremely high voltage, such as X-ray apparatus.4
'Ihe invention is hereinafter described in more detail in connection with the accompanying drawing, showing, by way of example, a preferred form of apparatus embodying the principles of the invention.
'I'he single gure of the drawing is a schematic illustration of the invention.
In the drawing there is shown a storage vessel I containing a conducting or semi-conducting 46 liquid 2, which is pumped up to pressure tank 3 by means of a suitable pump 4. 'I'he liquid in tank -3 escapes in the form of small drops through small nozzles or holes 5 and falls upon an intermediate storage vessel 6. 'An intense electric y field caused by the application of voltage to a.
plate 1 through connection 8 and a variable voltage rectifier 9, the latter of which is supplied from a 60 cycle power source, as shown, causes the escaping liquid drops flowing from nozzles-5 to acquire an electric charge which is given up to vessel 6 when the conducting liquid drops contact either the vessel 6 or the liquid contained therein. The potential built up on vessel 6 is utilized by any suitable device I0, herein shown in conventional box form, connected to vessel 6 by means of conductor II.
In order that the production of the high voltage may be a continuous process, it is preferred to drain the liquid out of vessel 6 continuously but 5 under such conditions that the liquid leaving the intermediate vessel carries no charge with it. This is accomplished by allowing the liquid in vessel 5 to flow therefrom in the form of relatively large drops I2 which have a small elec-` 10 trostatic capacity per unit of volume compared with the small drops I3 originally falling into the vessel 6. Thus the arrangement functions because of the difference in size of the drops I2 and i3. In the preferred embodiment, the large drops 15 l2 are arranged to leave vessel 6 in such a location and under such conditions that there is no electrostatic potential gradient; in other words, drops i2 carry no charge, and all the charge carried to vessel 6 by small drops I3 are stored 25 in the electrostatic capacity of vessel 6, thus building up a maximum of voltage or delivering a maximum of power to utilization device Ill. As shown in the drawing, the drops leaving vessel do so at points which are electrically 25 shielded so that substantially no charge is carried by the drops when they sever contact with the vessel.
It will be understood, of course, that the invention is not limited to the precise arrangement of 30 parts shown since these may be modified without departing from the spirit and scope ofthe invention.
