Book Description
Excerpt from The Brass World and Platers' Guide, 1913, Vol. 9: A Journal Devoted to the Art of Refining, Alloying, Casting, Rolling, Founding, and Electroplating of All the Non-Ferrous Metals That a gold plating solution should be run hot whenever possible as the deposit has a better color. And covers more thoroughly and more rapidly. That nickel solutions become alkaline by the introduction of potash or soda from the clean ing kettle and not from other causes. The tendency 6f a nickel solution is to become acid rather than alkaline unless an alkali is actually introduced. That a silver solution should be kept free from sediment or it will settle on the work and cause pits. That boracic acid is an excellent ingredient of nickel plating solutions as it produces a white deposit and prevents pitting. That sal-ammoniac in a nickel solution ih creases the conductivity and causes the anodes to dissolve more freely. That the amount of any metal deposited is dependent upon the number of amperes passing through the solution. Twice the number of amperes will give twice the weight of deposit in a given time.

Book Description
Excerpt from The Brass World and Platers' Guide, 1911, Vol. 7: A Monthly Journal The arrangement consists of two tackle blocks with a in. Rope in them. The top block is fastened to a jib crane and from it rod and breast-piece extend. This breast-piece and rod are for off - setting the strain exerted in pulling on the rope. The helper places the breast piece across his breast and then pulls on the rope. The caster steadies the tongs with his hands. The rod, attached to the breast piece, also serves to push the crane around to the molds. The rope does not burn as it is too far from the fire and a long hook is used to connect the crucible tongs and the lower tackle block. The advantage of the arrangement is that it provides a much more rapid means of pulling out the crucible than with a chain block, and it also is used for holding and steadying the crucible while it is being poured into the molds.
