Electrical news and engineering . s the question of circulation of the electrolyte and this type of cell each small pair of elements forms a unitby itself, so arranged in a vertical position and surroundedby a circulating envelope in the form of a duct that thetendency of the electrolyte and gases to rise is nut oljstruct-ed nor countercurrented, the result being that the flow ofelectrolyte adjacent to each active surface is maintaineduniform by the natural tendency of the gas bubbles to riseand the electrolyte to ascend as its density changes. Inother types of cells this natural condition of circulation doesnot exist to anything like the same degree, as. due to un-equal activity and the disposal of the plates, there is a gooddeal of countercurrenting tending to retain the gas bubbleson the surface of the plates and to restrict the circulationof the electrolyte, thus reducing their action. This superiorcurrent action tends also towards the high discharge effi-ciency indicated under the heading ? A Sin^li-Ilitp ISirimitional .Viiiimnlator Ilate Ihc shedding of active material which is so objeclion-al, not only because of reduction in the capacity of the plates,but also because of the shortcircuiting action at the bottomof the cells if not cleaned frequently, should be greatlyminimized by the unique features of construction, and alsoby the uniform activity of the surfaces promoted l)y theirdimensions and the efficient action of the An examination of Messrs.
