be held together by a strap, 20.

The tank is divided into an upper portion 2l'and a lower portion 22 by means of a circular flange, 23, resting upon a shoulder, 24, extending around the inside of the tank.

In this form of apparatus the anode itself is shown at 25 as bemg suspended from the 1, -dome of the part 1, or otherwise supported 20 thereby. The anode, 25, is of some suitable metal and is provided with appropriate means for connecting it to the external circuit. Into the upper and lower space in the tank a cooling medium such as oil, water, glycerin, or a forced draft of air may be introduced. In some instances natural air currents may be relied upon. The cooling fluid in the upper portion may enter at the pipe, 35, and may ass out orbe removed throu h the exit pipe, 26, after absorbing heat from the dome shaped element, 1, and the anode, 25.- If desired the structure may be given suificient heat radiating capacity and the fluid merely circulated within the same, transferrin heat from the rectifier to the tank. In li e manner, the cooling fluid may enter the lower space at the entering tube, 29,'and leave by the exit tube, 28; or the renewal of the fluid may be omitted and the tank distribute the heat externally. The consideration of the design of this apparatus brings out two major principles as to the main positive electrodes, namely,

I claim as my invention:

1. A. vapor rectifier consisting of a case of conducting material, a positive electrode, a liquid negative electrode, means for insulating the said electrodes from the case and an insulating sleeve or cylinder projecting below and above the surface. of the liquid and means for initiating a flow of current from the ositive electrode to that portion of the liquid electrode lying inside of said sleeve or cylinder.

2. A vapor rectifier consisting of a case of conducting material, a positive electrode, a liquid negative electrode, means for insulating the said electrodes from the case, an insulating sleeve-or cylinder projecting below 1 and above the surface of the liquid, and :means for initiating a flow of current from 'ithe ositive electrode to that portionof the liquid electrode lying inside of said cylin- 'der or sleeve, and an auxiliary electrode also located within said sleeve or cylinder.
