Beyond them, out near the end of the extension-arm, the electro- magnetic cranes of the huge main traveller were sorting and shifting forward a great heap of structural steel. The material thus handled came within the reach of the smaller traveller, which crouched upon the top-chords like a skeleton spider, swinging out the steel as wanted to the end of the unfinished suspension span.
The electro deposition of zinc has been subject to many patents, and the efforts to introduce it have been lamentable in both a mechanical and financial sense. Most authorities recommend a current density of 18 or 20 ampères per square foot of cathode surface, and aqueous solutions of zinc sulphate, acetate or chloride, ammonia, chloride or tartrate, as being the most suitable for deposition.
The tinfoil sticks to the back of the copper, and on the back of this is poured melted type-metal, until a solid plate has been formed, the surface of which is the copper facsimile and the body white metal. The electro metal plate, copper colored and bright on its surface, has now to go to the Here are two departments.
In fact, there seemed to be innumerable problems to warn Baron Kreiger, to get the list of the assassinations, to guard Miss Lowe against falling into the hands of her anarchist friends again, to find the murderer of Fortescue, to prevent the use of the electro- magnetic gun, and, if possible, to seize the anarchists before they had a chance to carry further their plans.
The wonderful completeness of Faraday's researches into the production of electricity from magnetism may be inferred from the fact that all the forms of magneto-electric induction known to-day namely, self-induction, or the induction of an active circuit on itself; mutual induction, or the induction of an active circuit on a neighboring circuit; and electro-magnetic induction, and magneto-electric induction, or the induction produced in conductors through which the magnetic flux from electro and permanent magnets respectively is caused to pass were discovered and investigated by him.
"In giving this very rough outline of the general mode of forming salts, the minutiae necessary for chemical work have altogether been avoided, and those parts alone are entered upon which are more immediately necessary for the electro metallurgist to know and practice for himself.
One-half the city itself tore loose and slid downward, lost in the debris of the avalanche of which it was a part. The remainder, wrenched and convulsed like a living thing in agony, cracked, crumbled and split, towers tumbling down and great fissures appearing in its walls. Its power plant and electro machinery went out of commission.
Consequently, it is not surprising to learn that wealthy iron-masters, the country gentry, and prosperous farmers no longer make the purchases of silver and fancy wares they did in the days that are no more. Black country magnates have discovered they can now do without many solid silver services, and even fairly well-to-do rural people find they can at a pinch put up with electro plate.
Impassive as Asiatics can be, I should much like for once just to watch the eyes of an eastern conjuror and magician when he saw the electro bath trick, and especially when done in the way and on the scale that may be witnessed at the Birmingham Newhall Street works. With regard to Mr.
With zinc the electrolytic and electro-thermal processes have not been able yet to compete with the older metallurgical method of distillation, but an important industry is electro- galvanizing, where a solution of zinc sulphate is deposited on iron and gives a protective coating.
