*The discharge 4vor 'deliveryplpe 21aA conbra-nzched-so astoconnect with'a pipe 30 the nected with the mercury pump 21 communicates not-:only with the feed pipe 22 but is Y f pipe 22 may be closed by a valve 34, and when a proper vacuum has been effected within the vacuum chamber of the casing 18 the said valve 34 may be opened for the purpose of spraying the mercury between the electrodes and 17 thereby avoiding the use of a speber. Thus as soon as a propervacuum is obthus the transformer or rectifier is set intoV r voperation without the assistance of a special cialexhaust pump for the said vacuum chamtained in the vacuum chamber, the rectier is energized, and the valve 34 is opened; and
starter, as is required in mercury rectiiers now. generally in use. s
To prevent crossing currents between the di'erent sets of electrodes, as also to prevent vshort circuiting, due to mercury spray which may accidently reach the casing 18, barriers 37 are preferably interposed between the sets of electrodes and also between the electrodes and such casing.
f From the foregoing itwill be understood that the invention presents certain advantages over mercury rectiiiers or transformers novi in use in that by electrically connecting aplu- 46 rality of sets of electrodes by'a plurality ofconducting areas are presented that more kcurrent may be rectiied by an apparatus of atomized sprays offmercury so much surface a given size than is possible by the mercury rectiersnow in use.
' As another advantage'of the invention itl may be mentioned that in the use of this im-l proved rectifying apparatus, no rpreheating of the anodes isnecessary, as the mercury spray or vapor becomes incandescent and thus imparts suilicient heat to the anodes tol enable them to function properly. Also the invention eliminates the necessity of an auX- iliary maintaining electrode, as also the necesi the streams of atomized mercury spray in the l sity of a special exhaust pump for the vacuum chamber, or a special starter for the apparatus.
By so directing the mercury or confining A direction of the anodes, a greater number of positive or ionized bodies are produced, thus increasing the electron stream to the anodes, and thereby eliminating random velocities at the crater of the mercury pool of the cathode. Also sputtering and bombardment of these mercury molecules causes the liberation l sprays.`
prising a vacuum chamber, a plurality of sets of spaced-apart electrodes therein and cornof ions and electrons produced by friction, and also carries down and precipitates the foreign gases so that the rectifier is completely freed from such gases.
It will be understood that the invention is not necessarily limited to the details of construction herein shown, as it is believed to be broadly new to connect a plurality of sets of electrodes, in a rectifier vacuum chamber, by means of a plurality of atomized mercury Having thus described my invention, I claim an desire to secure by Letters Patent:
v1. An, electric rectifying apparatus comprising anodes made of solid material, and means for electrically connecting said electrodes by a plurality of atomized mercury sprays projected from the cathodes against the anodes.
2. An electric rectifying apparatus comprising a vacuum chamber, a plurality of sets kof spaced-apart electrodes therein,v a mercu receptacle, a mercury force pump commumeating with said receptacle, a plurality of spray nozzles through which the mercury is forced from the cathodes to the anodes to form a plurality of atomized mercury sprays, pipeconnections between said pump and said 9 nozzles, and meansfor driving said pump.
3.' An electric rectifying apparatus comprising a casing affording a vacuumchamber,
a plurality of sets of electrodes in said chamber, a mercuryreceptacle, a plurality of spray lo nozzles in said chamber, means for forcing mercury through said nozzles to form a plurality of atomized mercury sprays between said electrodes, barriers between the sets of electrodes and also between the sets of electrodes and said casing to prevent cross currents, and means for returning the condensed mercury to said receptacle.
- 4. An electric rectifying apparatus comprising a vacuum chamber, spaced-apart electrodes therein, a mercury receptacle, a mercury pump communicating with said receptacle, spray nozzles in said chamber, pipe connections between said pump and'said nozzles, means for driving said pump, and suction means, operated by mercury forced upward by said pump, for exhausting air from said vacuum chamber.
