Theoretically 36 parts by weight of carbon are oxidized in the production of 54 parts of aluminium; practically the anodes waste at the same rate at which metal is deposited.
The anodes are made of retort-carbon or other chlorine-resisting material, and they are mounted in cells which serve as diaphragms.
The anodes and cathodes are separated by the special diaphragms, and each vessel is thus divided into ten anode or chlorine sections and ten cathode or caustic soda sections.
The installation consists of five large electrolytic vessels, each of which is fitted up with five anodes and six cathodes arranged alternately.
The anodes and cathodes in each vessel are connected up in parallel similar to an ordinary storage battery, but the five electrolytic vessels are connected up in series.
The anodes A, several in number, are suspended around the cathode from above.
Above this layer in A is fused salt, into which dip carbon anodes D.
They are first dissolved, and the salts obtained are electrolyzed, employing anodes of coke.
In this arrangement, the mercury being the cathode, plates or wires of copper constituting anodes are brought into contact with the water passing over the mercury in each "riffle.
Both the cathode and the anodes are, of course, maintained in contact with the poles of a suitable source of electrical supply.
As odds and ends of silver (from old anodes and silver residues) generally accumulate in the laboratory, it is often more convenient to make the solder one's self.
Tubes of the focus pattern with large platinum anodes are in general (in my experience) much more difficult to exhaust than tubes of the kind first described.
Supplementary anodes are sometimes used in difficult cases of this kind.
The principle usually followed in the electrolytic refining of metals is to cast the impure metal into plates, which are exposed as anodes in a suitable solvent, commonly a salt of the metal under treatment.
It supplies low pressure currents to the starting anodes of the rectifier tube.
The static dischargers consisting of horn gaps in series with resistance, are connected between the anodes and the cathode in order to protect the tubes and other apparatus from excessive electrical strains.
Since there is always a pressure on one of the three anodes in the right direction, a reactance coil is not necessary.
The rectifier tube is an exhausted glass vessel in which are two graphite anodes A, A', and one mercury cathode B.
As shown in the figure, ~the rectifier consists essentially~ of a glass bulb into which are sealed two iron or graphite anodes and one mercury cathode, and a small starting electrode.
It consists of an exhausted glass vessel containing one anode or positive terminal in each of the two upper arms, two mercury starting anodes and a cathode or negative terminal of mercury at the bottom of the tube.
An inner casing of wood which projects a few inches above the lead lining is necessary in order to avoid any chance of "short circuiting" or damage to the lead from the accidental falling of anodes or any article which might cut the lead.
The tank should be sufficiently wide to take the largest article for plating, and to admit of the anodes being moved nearer to or further from the article.
The texture of the inner portions of these foreign anodes would lead one to infer that the metallurgy of nickel was very primitive.
If this is desired, it is far better to use a separate bath, using anodes of suitable composition.
If the copper has not been removed, it will deposit on the anodes when the bath is at rest.
All other anodes or cathodes of which we have obtained any knowledge belong to physical phenomena only.
The anodes consist of carbon blocks suspended in the molten bath, and the cathode consists of the carbon lining of the furnace.
In these processes the solution used consists either of zinc sulphate or of zinc chloride, the anodes consisting of metallic lead or of carbon, and the cathodes of pure zinc sheets.
For electroplating of copper, anodes of metallic copper, having a surface equal to that of the articles to be coated, are used.
As the operation proceeded, it was found that the voltage had to be raised until it became prohibitive, while the anodes rapidly became honeycombed through and, crumbling away, filled up the space at the bottom of the vat.
Six anodes were suspended, alternately with four cathodes, in a saturated solution of copper sulphate in a cylindrical fire-clay trough, all the anodes being connected in one parallel group, and all the cathodes in another.
The electrolyte, when too impure for further use, is commonly recrystallized, or electrolysed with insoluble anodes to recover the copper.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "anodes" in a variety of sentences. We hope that you will now be able to make sentences using this word.
