An electrolytic cell comprising a plurality of anodes and cathodes and a separator positioned between each anode and adjacent cathode to form a plurality of anode compartments and cathode compartments, in which a barrier member is positioned at an upper part of the cell between an anode and an adjacent separator, or between a cathode and an adjacent separator, and which, in operation shields the separator from contact with a gaseous product of electrolysis which may collect in an upper part of t...

Disclosed is an improved electrolytic cell comprising a microporous separator of the diaphragm type, anolyte and catholyte compartments made of plastic materials and metal electrodes with a multipicity of perforations in the electrochemically active area made preferentially by punching perforations of pre-selected shapes. Also disclosed is the presence of a separation chamber located on top and being an integral part of the anolyte compartment for separating the anodic gases from the expent anol...

An electrolytic cell and electrolytic process wherein the cell includes a metal anode (such as a lithium anode), a cathode and an electrolyte. A surface layer which is applied to the metal anode enables transfer of ions from the metal anode to the electrolyte and thus allows the ions to pass back into contact with the metal anode. The surface layer is also electronically conductive so that the ions will be uniformally attracted back onto the metal anode during electrodeposition to, in turn, subs...

An electrolytic cell for the recovery of silver from a photographic fixer solution is of generally cylindrical configuration. The cell has a screw-on lid that carries the disposable cathode of the cell. Inlet and outlet for the solution are at the bottom of the cell. The anode is tubular and extends upwardly from the outlet at the base of the cell towards the lid. The cathode is easily replaced, together with the lid, and flow through and the dimensions of the cell are arranged to avoid entrapme...

An electrolytic capacitor utilizing a cannister with an indentation for compressing a silicone potting compound to supply pressure on a capacitor cartridge is described. The indentation includes a bead that extends around an outer surface of the cannister.

An electrolytic cell includes at least a first and a second, generally planar, membrane-supporting frame each having a plurality of through-holes. Each is sealed to a plurality of annular coupling members located between the frames and generally aligned with a respective through-hole of each frame to thereby define a plurality of sealed conduits through the frames. Each coupling member is attached in a sealed relationship to the first frame by a number of bolts passing through oversized holes in...

An electrolytic cell of the filter-press type which comprises plate-like anodes, cathodes, and gaskets of an electrically-insulating material, and an ion-exchange membrane between each anode and adjacent cathode to form in the cell a plurality of anode compartments and cathode compartments, the gaskets, and optionally the anodes and cathodes, each containing apertures therein which form headers from which liquors may be charged to the anode and cathode compartments of the cell and to which produ...
